Description

Technical Field

[0001] This utility model relates to the technical field of gas spring installation tools, and in particular to a gas spring installation tool. Background Technology

[0002] Gas springs are primarily used for support and have a unique working condition, stabilizing only at their shortest and longest extreme positions. They cannot stop automatically within their stroke, making them widely used in various industries, such as crane booms in construction machinery and doors for large equipment. However, gas springs with large load-bearing capacities, due to their high internal energy storage, cannot be safely disassembled and assembled manually. They must be secured and pre-compressed with specialized tools to reduce the safety risks caused by popping out or retracting, ensuring safe and smooth operation.

[0003] Patent publication number "CN216543141U" discloses "a gas spring assembly / disassembly tool," comprising: a nut sleeve, mainly composed of a cylindrical hollow part and a nut part, with nut parts at both ends of the hollow part; the inner wall of the hollow part is smooth, and the inner wall of the nut part is threaded; and screws, with screws at both ends of the nut sleeve; each screw includes a screw part and a semi-circular rod part, with the screw parts of the two screws respectively engaging with the nut parts of the nut sleeve, and the semi-circular rod parts of the two screws slidingly engaging with each other within the hollow part of the nut sleeve. The overall design is reasonable and the structure is symmetrical, allowing for easy one-handed operation and greater convenience.

[0004] When installing the gas spring in the aforementioned patent, it needs to be secured between the hooks. If the length of both ends of the air spring is too long, the installation process will be extremely difficult to control. At this time, one end of the gas spring that has been secured between the hooks is very likely to suddenly lift up, which may damage the gas spring and surrounding equipment, or even injure the operator and cause safety accidents. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a gas spring installation tool.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas spring installation tool, including a nut sleeve, wherein control mechanisms are respectively provided at both ends of the nut sleeve;

[0009] The control mechanism includes a contact block and a working groove. The working groove is respectively opened on both sides of the inner wall of the contact block and extends through the interior. A detachable small screw is rotatably connected to the bottom wall of the working groove. A detachable auxiliary rod is fixedly installed on the bottom wall of the working groove. The top of the small screw and the top of the auxiliary rod are slidably connected through the top wall of the working groove and the top surface of the contact block, respectively. A control block is screwed to the outside of the small screw. One end of the control block is slidably connected to the outside of the auxiliary rod.

[0010] By adopting the above technical solution, when installing or disassembling a gas spring, rotating the small screw drives the outer screwed control block to move smoothly downwards. As the control block moves downwards, it can apply constraints and control to both ends of the gas spring during installation or disassembly, thus fundamentally preventing the phenomenon of one end of the gas spring suddenly lifting up during installation or disassembly. This solves the problem that when installing a gas spring, it is necessary to clamp it between hooks. If the length of both ends of the air spring is too long, the installation process will be extremely difficult to control. At this time, one end of the gas spring that has been clamped between the hooks is very likely to suddenly lift up, which may damage the gas spring and surrounding equipment, or even injure the operator and cause safety accidents.

[0011] In a preferred embodiment of the gas spring installation tool described in this utility model, the nut sleeve is screwed with a first screw and a second screw that penetrate the interior at both ends.

[0012] By adopting the above technical solution, the nut sleeve can effectively provide a stable screwing effect for the first screw and the second screw that are screwed to both ends respectively. When the work is finished, rotating the nut sleeve can effectively shrink the first screw and the second screw, making it highly portable and easy to store.

[0013] In a preferred embodiment of the gas spring installation tool described in this utility model, a lever is fixedly installed on the outer side of the nut sleeve.

[0014] By adopting the above technical solution, if a large force needs to be applied, it is often difficult to achieve the desired effect by simply turning the nut sleeve by hand. At this time, the actuating rods symmetrically installed on the outside of the nut sleeve can play a key role. With the advantage of the extended lever arm provided by the actuating rod, the operator can easily apply a larger force, thereby making the nut sleeve rotate efficiently and smoothly.

[0015] In a preferred embodiment of the gas spring installation tool described in this utility model, one end of the first screw and one end of the second screw are respectively rotatably connected to the rear end face of the contact block of the control mechanism.

[0016] By adopting the above technical solution, the first screw and the second screw extend and retract synchronously, which can efficiently push the abutment block to move synchronously to both sides. During the displacement process, the abutment block can accurately abut against the gas spring at the installation position, providing stable and powerful positioning support for the installation of the gas spring.

[0017] In a preferred embodiment of the gas spring installation tool described in this utility model, reinforcing ribs are fixedly installed on the rear side of the contact block of the control mechanism.

[0018] By adopting the above technical solution, the abutment block can effectively provide a stable installation position for the reinforcing ribs installed on the rear side.

[0019] In a preferred embodiment of the gas spring installation tool described in this utility model, the bottom ends of the reinforcing ribs are respectively fixedly installed on the bottom wall of the rear end of the contact block of the control mechanism.

[0020] By adopting the above technical solution, the bottom ends of the reinforcing ribs are respectively installed on the bottom wall of the rear end of the contact block, which can effectively strengthen the contact block.

[0021] (III) Beneficial Effects

[0022] This utility model provides a gas spring installation tool. It has the following advantages:

[0023] 1. By adding a control mechanism, during the installation or disassembly of the gas spring, rotating the small screw drives the outer screw-connected control block to move smoothly downwards. As the control block moves downwards, it can apply constraints and control to both ends of the gas spring during installation or disassembly, thus fundamentally preventing the phenomenon of one end of the gas spring suddenly lifting up during installation or disassembly. This solves the problem that when installing a gas spring, it is necessary to clamp it between hooks. If the length of both ends of the air spring is too long, the installation process will be extremely difficult to control. At this time, one end of the gas spring that has been clamped between the hooks is very likely to suddenly lift up, which may damage the gas spring and surrounding equipment, or even injure the operator and cause safety accidents.

[0024] 2. By adding a lever, if a larger force needs to be applied, it is often difficult to achieve the desired effect by simply turning the nut sleeve by hand. At this time, the levers symmetrically installed on the outside of the nut sleeve can play a key role. With the advantage of the extended lever arm provided by the lever, the operator can easily apply a larger force, thereby making the nut sleeve rotate efficiently and smoothly.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Reference Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides a gas spring installation tool including a nut sleeve 1, and control mechanisms 5 are respectively provided at both ends of the nut sleeve 1.

[0034] The control mechanism 5 includes a contact block 51 and a working groove 52. The working groove 52 is respectively opened on both sides of the inner wall of the contact block 51 and extends through the interior. The bottom wall of the working groove 52 is rotatably connected to a detachable small screw 53. The bottom wall of the working groove 52 is fixedly installed with a detachable auxiliary rod 54. The top end of the small screw 53 and the top end of the auxiliary rod 54 are slidably connected through the top wall of the working groove 52 and the top surface of the contact block 51, respectively. The outer side of the small screw 53 is screwed with a control block 55. One end of the control block 55 is slidably connected to the outer side of the auxiliary rod 54.

[0035] Specifically, the nut sleeve 1 has a first screw 2 and a second screw 3 that pass through its interior, respectively, screwed to both ends.

[0036] Furthermore, when the control mechanism 5 is installing or removing the gas spring, it rotates the small screw 53 to drive the outer screwed control block 55 to move smoothly downward. As the control block 55 moves downward, it can apply constraints and control to both ends of the gas spring that is in the installation or removal state, thus fundamentally preventing the phenomenon of one end of the gas spring suddenly lifting up during the installation or removal process. One end of the control block 55 is slidably connected to the outside of the auxiliary rod 54. The auxiliary rod 54 can play an effective limiting control role. The bottom end of the auxiliary rod 54 is detachably installed on the bottom wall of the working groove 52. The bottom end of the small screw 53 is also detachably rotatably connected to the bottom wall of the working groove 52. After the installation or removal of the gas spring is completed, simply pull out the insert that passes through the bottom end of the small screw 53 and the auxiliary rod 54, and the control block 55 can be smoothly detached from the gas spring that has been installed or removed. The operation is convenient and efficient. The working groove 52 is opened on both sides of the inner wall of the contact block 51 and passes through the interior.

[0037] The nut sleeve 1 can effectively provide a stable screwing effect for the first screw 2 and the second screw 3, which are screwed to both ends respectively. When the work is finished, rotating the nut sleeve 1 can effectively shrink the first screw 2 and the second screw 3, making it highly portable and easy to store.

[0038] Example 2

[0039] Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment is based on the previous embodiment. A toggle rod 4 is fixedly installed on the outside of the nut sleeve 1. One end of the first screw 2 and the second screw 3 are rotatably connected to the rear end face of the contact block 51 of the control mechanism 5.

[0040] Specifically, reinforcing ribs 6 are fixedly installed on the rear side of the contact block 51 of the control mechanism 5, and the bottom ends of the reinforcing ribs 6 are fixedly installed on the rear bottom wall of the contact block 51 of the control mechanism 5.

[0041] Furthermore, if a larger force needs to be applied, it is often difficult to achieve the desired effect by simply turning the nut sleeve 1 by hand. At this time, the actuating rod 4, which is symmetrically installed on the outside of the nut sleeve 1, can play a key role. With the advantage of the extended lever arm provided by the actuating rod 4, the operator can easily apply a larger force, thereby making the nut sleeve 1 rotate efficiently and smoothly.

[0042] The first screw 2 and the second screw 3 extend and retract synchronously, which can efficiently push the abutment block 51 to move synchronously to both sides. During the displacement, the abutment block 51 can accurately abut against the gas spring at the installation position, providing stable and powerful positioning support for the installation of the gas spring.

[0043] The bottom ends of the reinforcing ribs 6 are respectively installed on the bottom wall of the rear end of the contact block 51. In this way, the contact block 51 can be effectively reinforced.

[0044] Working principle: If a large force needs to be applied, it is often difficult to achieve the desired effect by simply turning the nut sleeve 1 by hand. At this time, the lever 4 symmetrically installed on the outside of the nut sleeve 1 can play a key role. With the advantage of the extended lever arm provided by the lever 4, the operator can easily apply a larger force, thereby making the nut sleeve 1 rotate efficiently and smoothly.

[0045] The first screw 2 and the second screw 3 extend and retract synchronously, which can efficiently push the abutment block 51 to move synchronously to both sides. During the displacement, the abutment block 51 can accurately abut against the gas spring at the installation position, providing stable and powerful positioning support for the installation of the gas spring.

[0046] When the control mechanism 5 is installing or removing the gas spring, it rotates the small screw 53 to drive the outer screwed control block 55 to move smoothly downward. As the control block 55 moves downward, it can apply constraints and control to both ends of the gas spring that is being installed or removed, thus fundamentally preventing the phenomenon of one end of the gas spring suddenly lifting up during the installation or removal process. One end of the control block 55 is slidably connected to the outside of the auxiliary rod 54. The auxiliary rod 54 can play an effective limiting control role. The bottom end of the auxiliary rod 54 is detachably installed on the bottom wall of the working groove 52. The bottom end of the small screw 53 is also detachably rotatably connected to the bottom wall of the working groove 52. After the installation or removal of the gas spring is completed, simply pull out the insert that passes through the bottom end of the small screw 53 and the auxiliary rod 54, and the control block 55 can be smoothly detached from the gas spring that has been installed or removed. The operation is convenient and efficient. The working groove 52 is opened on both sides of the inner wall of the contact block 51 and passes through the interior.

[0047] The nut sleeve 1 can effectively provide a stable screwing effect for the first screw 2 and the second screw 3, which are screwed to both ends respectively. When the work is finished, rotating the nut sleeve 1 can effectively shrink the first screw 2 and the second screw 3, making it highly portable and easy to store.

[0048] The bottom ends of the reinforcing ribs 6 are respectively installed on the bottom wall of the rear end of the contact block 51. In this way, the contact block 51 can be effectively reinforced.

[0049] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
