Description

[Technical field]

[0001] The utility model mainly relates to a guide rail buffer structure. [Background technology]

[0002] The buffer structure plays a vital role in mechanical equipment. It can effectively reduce the impact and vibration of the equipment during movement, protect the equipment from damage, and improve the service life and stability of the equipment. In addition, a good buffer structure can also improve the handling performance of the equipment and improve the comfort and satisfaction of users.

[0003] The most commonly used existing impact buffers are gas rods or hydraulic rods, which absorb kinetic energy by compressing gas or liquid to achieve the effect of reducing the buffer. For gas rods, each gas rod has a corresponding impact limit value. When the limit value is exceeded, the gas rod is easily damaged and the impact resistance is lost. Therefore, how to improve the impact resistance of gas rods to improve the buffering effect has become the direction of our research. [Contents of the utility model]

[0004] In order to solve at least one of the above problems, the utility model proposes a new structural solution. The guide rail buffer structure adopts the following technical solution:

[0005] A guide rail buffer structure comprises a cylinder, a rotating nut and a spring;

[0006] The cylinder comprises a cylinder body and a piston rod, the cylinder body is provided with threads, and the rotating nut is provided with threads screwed to the cylinder body; the spring is sleeved with the cylinder body, the end of the spring is connected to the rotating nut, and the head end of the spring is movably abutted against the piston rod to push the rotating nut through the compression spring.

[0007] Preferably, the edge of the rotating nut is provided with teeth, and the teeth are provided with through holes for the spring end to be connected and fixed.

[0008] Preferably, the piston rod has a baffle, and the piston rod is movably connected to the head end of the spring through the baffle.

[0009] Preferably, both the cylinder and the piston rod are provided with locking holes.

[0010] Compared with the background technology, the utility model has the following beneficial effects:

[0011] The utility model proposes a guide rail buffer structure, which includes a cylinder, a rotating nut and a spring. The structure adopts a double-layer buffering measure. The first is that the cylinder cooperates with the piston rod to form a buffer, and the second is that the spring, the rotating nut and the thread of the cylinder cooperate. When the piston rod is impacted, the piston rod retracts to make the baffle contact with the head end of the spring, and the spring is compressed. The compressed spring force drives the rotating nut to rotate on the thread of the cylinder body through its end, thereby achieving the purpose of unloading, thereby improving the impact resistance of the piston rod. At the same time, the spring can also play a certain buffering role when the cylinder is damaged. It has the advantages of simple structure, compact cooperation, fast fixation, and easy disassembly; therefore, it is a product with superior performance in both technical and economic aspects.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, but cannot be understood as limiting the utility model.

[0017] The preferred embodiment provided by the utility model is as follows: Figure 1 and Figure 2 As shown, a guide rail buffer structure includes a cylinder 1, a rotating nut 2 and a spring 3. The cylinder 1 and the piston rod 5 are both provided with a locking hole 11 so as to be installed on other components.

[0018] The cylinder 1 includes a cylinder body 4 and a piston rod 5. The cylinder body 4 is provided with a thread 41, and the rotating nut 2 is provided with a thread 41 screwed to the cylinder body 4. The spring 3 is sleeved on the cylinder body 4, and the end of the spring 3 is connected to the rotating nut 2. The spring is compressed to cause the spring to deform, and the force transmitted to the end of the spring will provide a rotational force to the rotating nut. The head end of the spring 3 is movably in contact with the piston rod 5 to push the rotating nut 2 by compressing the spring 3.

[0019] The edge of the rotating nut 2 is provided with teeth 21, and the teeth 21 is provided with a through hole 22 for the end of the spring 3 to be connected and fixed. The end of the spring 3 passes through the through hole 22 and is bent to be fastened to the rotating nut 2. The piston rod 5 has a baffle 51, and the piston rod 5 is movably connected to the head end of the spring 3 through the baffle 51.

[0020] The utility model proposes a guide rail buffer structure, which includes a cylinder 1, a rotating nut 2 and a spring 3. The structure adopts a double-layer buffering measure. The first is that the cylinder 1 cooperates with the piston rod 5 to form a buffer, and the second is that the spring 3, the rotating nut 2 and the thread 41 of the cylinder 1 cooperate. When the piston rod 5 is impacted, the piston rod 5 retracts to make the baffle 51 contact with the head end of the spring 3, and the spring 3 is compressed. The compressed spring 3 drives the rotating nut 2 to rotate on the thread 41 of the cylinder body 4 through its end, thereby achieving the purpose of unloading force, thereby improving the impact resistance of the piston rod 5. At the same time, when the cylinder 1 is damaged, the spring 3 can also play a certain buffering role.
