Description

Technical Field

[0001] This utility model belongs to the technical field of gas spring connection structure, specifically relating to a gas spring connection structure. Background Technology

[0002] A gas spring, also known as a gas valve, is a device that uses the pressure of compressed gas within a sealed cavity to provide support or cushioning. Its core components typically include a cylinder, piston rod, piston, and sealing structure. Gas springs are widely used in numerous fields due to their advantages, such as providing constant support force, smooth movement, and long service life, including the automotive industry (trunk lids, hoods, seat adjustments), the furniture industry (cabinet doors, office chair height adjustments), medical devices (hospital bed adjustments), and industrial equipment (equipment doors, protective cover opening and closing). Their main functions are to achieve relative movement between components, provide support force, or assist in lifting and positioning.

[0003] In practical applications of gas springs, both ends (cylinder end and piston rod end) need to be reliably connected to equipment or structural components. Common connection methods include threaded connections, ball joint connections (such as ball head pins and ball sockets), and pin connections. However, these gas springs are not convenient to install and disassemble (especially during maintenance or replacement). For example, threaded connections usually require special tools for tightening or loosening, which is particularly inconvenient when operating space is limited; ball head or pin connections often require aligning at a specific angle or position and applying considerable force to press the ball head into the socket or insert the pin during installation, and disassembly is equally laborious and may require special tools to pry. These operations are not only time-consuming and labor-intensive, increasing maintenance costs and workload, but their inconvenience is even more pronounced in situations with limited space or requiring frequent disassembly and assembly (such as production line equipment maintenance or the interior of complex mechanical structures), affecting the overall maintenance efficiency of the equipment. Therefore, we propose a gas spring connection structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that current gas springs are not convenient to disassemble and assemble in situations with narrow spaces or where frequent disassembly and assembly are required, which affects the overall maintenance efficiency of the equipment.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A gas spring connection structure includes a gas spring body, connecting ends fixedly installed at both ends of the gas spring body, and two connecting components adapted to the connecting ends. The connecting components include an L-shaped fixing seat, a threaded post, a fixing post fixedly installed on the L-shaped fixing seat, and a locking member disposed on the fixing post. The threaded post is fixedly installed at the lower end of the L-shaped fixing seat.

[0007] Further defining the locking component, the locking element includes a fixed cylinder, a sleeve movably fitted onto the fixed cylinder, two connecting blocks fixedly installed on the inner wall of the sleeve, a toggle ring, and multiple movable balls. The fixed cylinder has an annular groove and multiple mounting grooves adapted to the movable balls. The mounting grooves are connected to the annular groove and the inner side of the fixed cylinder. The toggle ring is movably installed in the annular groove. The fixed cylinder has a strip-shaped opening connected to the annular groove. The end of the connecting block passes through the strip-shaped opening and is fixedly connected to the toggle ring. The multiple movable balls are movably installed in the multiple mounting grooves. The end of the fixed cylinder away from the sleeve has an annular protrusion. A compression spring is fitted on the fixed cylinder between the sleeve and the annular protrusion. The fixed post has an annular groove. With this structural design, when the fixed sleeve is fitted onto the fixed post, and the sleeve abuts against the wall of the annular groove under the elastic force of the compression spring, multiple movable balls will be pushed into the mounting groove by the push ring. The ends of the movable balls will be locked into the annular groove on the fixed post through the mounting groove, thereby locking the connecting end located on the fixed post.

[0008] Furthermore, the actuating ring has a chamfered edge on the side closest to the movable ball. This structural design allows the chamfered edge of the actuating ring to smoothly push the movable ball into the mounting groove when the actuating ring moves.

[0009] Furthermore, a force-bearing ring is fixedly installed at the end of the sleeve, and the surface of the force-bearing ring is coated with an anti-slip rubber layer. This structural design allows the anti-slip rubber layer to increase the friction between the hand and the force-bearing ring, facilitating the movement of the sleeve.

[0010] Furthermore, the L-shaped fixing seat has reinforcing ribs at the bend, and the L-shaped fixing seat is made of carbon steel. This structural design leverages the high hardness and strength of carbon steel, and the reinforcing ribs further enhance the structural strength of the L-shaped fixing seat.

[0011] Furthermore, a bearing is provided on the inner side of the connecting end, and the connecting end is rotatably connected to the fixed column through the bearing. This structural design reduces the resistance when the connecting end rotates, making the use of the gas spring smoother.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] In this invention, when installing the gas spring body, simply attach the connecting ends at both ends to the fixing posts of the two connecting components, and lock the connecting ends with the locking parts. The locking parts can be disassembled without the aid of other auxiliary tools, making it suitable for occasions with narrow spaces or where frequent disassembly and assembly are required, and more convenient to use.

[0030] like Figures 1-5 As shown, a gas spring connection structure of this utility model includes a gas spring body 1, connecting ends 2 fixedly installed at both ends of the gas spring body 1, and two connecting components 3 adapted to the connecting ends 2. The connecting components 3 include an L-shaped fixing seat 31, a threaded post 32, a fixing post 33 fixedly installed on the L-shaped fixing seat 31, and a locking member 34 provided on the fixing post 33. The L-shaped fixing seat 31 is provided with reinforcing ribs at the bend. The L-shaped fixing seat 31 is made of carbon steel. The threaded post 32 is fixedly installed at the lower end of the L-shaped fixing seat 31. A bearing is provided on the inner side of the connecting end 2. The connecting end 2 is rotatably connected to the fixing post 33 through the bearing.

[0031] The locking component 34 includes a fixed cylinder 341, a sleeve 342 movably fitted onto the fixed cylinder 341, two connecting blocks 343 fixedly installed on the inner wall of the sleeve 342, a toggle ring 344, and multiple movable balls 345. The fixed cylinder 341 has an annular groove and multiple mounting grooves adapted to the movable balls 345. The mounting grooves communicate with the annular groove and the inner side of the fixed cylinder 341. The toggle ring 344 is movably installed in the annular groove. The side of the toggle ring 344 closest to the movable balls 345 is chamfered. The fixed cylinder 341 has a strip-shaped opening communicating with the annular groove. The end of the connecting block 343 passes through the strip-shaped opening and is fixedly connected to the toggle ring 344. The multiple movable balls 345 are movably installed in the multiple mounting grooves. The end of the fixed cylinder 341 away from the sleeve 342 has an annular protrusion. A compression spring 346 is fitted between the sleeve 342 and the annular protrusion on the sleeve 341. An annular groove 331 is provided on the fixing post 33. When the actuating ring 344 abuts against the groove wall of the annular groove under the action of the compression spring 346, the actuating ring 344 has a limiting effect on the movable ball 345, which can push the movable ball 345 to fit tightly against the groove wall of the mounting groove. At this time, part of the movable ball 345 enters the inner cylinder wall of the fixing sleeve 341 through the mounting groove. If the fixing sleeve 341 is fitted on the fixing post 33, the movable ball 345 will be stuck into the annular groove 331, producing a locking effect, thereby locking the connecting end 2. A force-bearing ring 4 is fixedly installed at the end of the sleeve 342. The surface of the force-bearing ring 4 is coated with an anti-slip rubber layer, which can increase the friction between the operator's hand and the force-bearing ring 4, making it easy to use.

[0032] The method of using this utility model is as follows:

[0033] During installation, the two connecting components 3 are fixed to two installation points (such as the inner panel of the tailgate and the side panel of the car body) by threaded post 32. Then, the connecting ends 2 at both ends of the gas spring body 1 are respectively fitted onto the fixing posts 33 of the two connecting components 3. After fitting, take the locking part 34, align the sleeve 342 end of the fixing cylinder 341 with the fixing post 33, and move the sleeve 342 away from the fixing post 33 and squeeze the compression spring 346 with your finger through the force ring 4. Then push the locking part 34 as a whole to fit the fixing cylinder 341 onto the fixing post 33. At this time, release your finger, and the sleeve 342 will rebound under the elastic force of the compression spring 346. The movable ball 345 is subjected to the force of the actuating ring 344 and is inserted into the annular groove 331 of the fixing post 33 through the installation groove. At this time, the installation is completed.

[0034] When disassembly is required, hook the force ring 4 with your finger to compress the compression spring 346 until the actuating ring 344 in the annular groove releases its resistance to the movable ball 345. At this point, the locking part 34 can be easily removed from the fixing post 33, thus completing the disassembly of the gas spring body 1.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
