This type of gas spring is suitable for products that require angle adjustment, height adjustment, or position holding, such as medical beds, dental treatment chairs, passenger seats, office chairs, adjustable furniture, and industrial control panels.
In some product classifications, Gasoblock is commonly used for applications that require angle adjustment and position locking, while Gasohite is often used in chair and seat height adjustment mechanisms. This article explains the features, applications, and key differences between Gasoblock and Gasohite.
What Is a Locking Gas Spring?
A locking gas spring is a gas-assisted support component that can control movement during its stroke and hold a structure at a required position.Compared with a standard non-locking gas spring, a locking gas spring includes the basic components such as a pressure cylinder, piston rod, piston, seals, compressed gas, and a small amount of oil. In addition, it also includes a controllable valve mechanism.
When the valve is opened, the piston rod can extend or retract, allowing the user to adjust the angle, height, or position of the product. When the valve is closed, the internal medium is restricted from flowing, and the piston rod stops moving, keeping the structure in the selected position.
Locking gas springs are commonly used for:
● Angle adjustment
● Height control
● Position holding
● Load assistance
● Reducing operating force
● Equipment structures that require repeated positioning
How Does a Locking Gas Spring Work?
The supporting force of a locking gas spring mainly comes from compressed gas sealed inside the cylinder, commonly nitrogen. The key difference between a locking gas spring and a non-locking gas spring is the internal valve mechanism that controls whether the piston rod can move or stop.The Piston Rod Can Move When the Release Mechanism Is Operated
When the user presses a button, lever, cable, pedal, or other release mechanism, the internal valve opens.At this moment, the piston rod can extend or retract under external force and internal gas pressure. This allows the bed board, seat, backrest, tabletop, or control panel to be adjusted to the required position.
The Piston Rod Locks When the Release Mechanism Is Released
When the user releases the control mechanism, the valve closes, restricting the flow of the internal medium. The piston rod then stops at the current position.For example, a locking gas spring can help hold:
● The backrest angle of a medical bed
● The backrest position of a passenger seat
● The adjustment angle of a dental treatment chair
● The height of an office chair or work chair
● The position of an adjustable tabletop or control panel
Different Designs Affect Locking Rigidity
The stability of a locking gas spring after locking depends on its internal structure and medium configuration.Some products, such as leisure chairs or general furniture, may allow slight elastic movement after locking. However, medical equipment, examination beds, or structures that carry higher loads usually require higher locking rigidity and better positional stability.
Main Features of Locking Gas Springs
Position Holding During Adjustment
The main feature of a locking gas spring is that it can hold the product at the required angle or height after adjustment.For example, a medical bed backrest does not only need to be fully flat or fully raised. It may need to be adjusted to different angles according to the patient’s condition or care requirements.
Support and Reduced Operating Effort
A locking gas spring is not only a positioning component. It also uses internal force to share part of the structural load.When users adjust a heavier bed board, seat backrest, tabletop, leg support, or control panel, the gas spring helps reduce the required operating force and makes the adjustment smoother and easier.
Suitable for Products That Require Repeated Adjustment
Locking gas springs are especially suitable for structures that need frequent position changes, such as medical beds, passenger seats, office chairs, dental chairs, and adjustable furniture.These products do not only require support. They also need to be adjusted and fixed in different positions according to different usage scenarios.
What Is the Difference Between Locking and Non-Locking Gas Springs?
Both locking and non-locking gas springs can provide supporting force, but their design purposes are different.| Comparison Item | Non-Locking Gas Spring | Locking Gas Spring |
|---|---|---|
| English Name | Non-Locking Gas Spring | Locking / Lockable Gas Spring |
| Main Function | Opening assistance, support, damping | Position adjustment, angle holding, height control |
| Control Mechanism | Usually none | Valve or release mechanism |
| Position Holding | Cannot actively lock at any selected position | Can hold a required position depending on design |
| Common Operation | Extends and retracts with the lid or tailgate | Released by button, lever, cable, or pedal |
| Common Applications | Automotive tailgates, engine hoods, furniture lift-up doors, machine covers | Medical beds, passenger seats, office chairs, dental chairs, adjustable furniture |
If the product needs to be adjusted to a specific angle or height and then held in position, a locking gas spring should be considered.
What Is Gasoblock? Features and Applications
Gasoblock can be regarded as a type of locking gas spring application name. It is commonly used for products that require angle adjustment, backrest positioning, or structural locking.This type of gas spring uses a release mechanism to control the internal valve. When the user operates the control device, the piston rod can move. When the operation stops, the gas spring holds the selected position.
