Description

Technical Field

[0001] This utility model belongs to the field of buffer pins, and specifically relates to an impact-resistant adaptive buffer pin. Background Technology

[0002] In the field of mechanical transmission, traditional pins have many problems under conditions of high impact and frequent vibration.

[0003] Traditional pins are typically rigid structures, unable to effectively absorb and disperse impact forces, making them prone to damage under high-impact conditions. Furthermore, traditional pins lack effective cushioning mechanisms, leading to fatigue damage of the pins and connecting components in environments with frequent vibrations, significantly shortening their service life. In addition, the lack of cushioning increases friction between the pins and connecting components, accelerating wear and further reducing system stability and reliability, severely impacting the mechanical system's lifespan and operating efficiency, and increasing maintenance costs and downtime.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide an impact-resistant adaptive buffer pin. Through the buffer components distributed in a ring inside the pin A seat, effective buffering of radial impact is achieved; at the same time, the liquid storage chamber inside the pin B tube, in conjunction with the hydraulic oil, allows the hydraulic oil to disperse the pressure when the pin B tube is squeezed, thus avoiding excessive local pressure and damage to local areas.

[0006] Technical Solution: To achieve the above objectives, this utility model provides an impact-resistant adaptive buffer pin, comprising: a pin A seat and a pin B tube, wherein a connecting pipe is provided in the middle of the pin A seat; the pin B tube is inserted into the connecting pipe to form a complete pin, and the two are connected by threads; several sets of buffer components are radially arranged inside the wall of the connecting pipe; the two ends of the buffer components respectively abut against the inner wall of the connecting pipe and the outer wall of the pin B tube; a liquid storage chamber is provided inside the pin B tube; the liquid storage chamber is arranged axially along the pin B tube and has several branches radially along the pin B tube; hydraulic oil is provided in the liquid storage chamber. The buffer components can automatically adjust the buffering force according to different impact forces to achieve adaptive buffering, so that the pin can maintain a good buffering effect under different working conditions; at the same time, when the hydraulic oil in the liquid storage chamber is under pressure, it will distribute the impact force to the entire pin B tube through hydrostatic transmission, effectively buffering the impact and improving the impact resistance.

[0007] Furthermore, the buffer assembly includes: an upper moving block, a lower moving block, a telescopic rod, and a spring; the upper and lower moving blocks are connected by the telescopic rod; the spring is mounted on the telescopic rod, with its two ends abutting against the upper and lower moving blocks respectively; the upper end of the upper moving block abuts against the inner wall of the connecting pipe; the lower end of the lower moving block abuts against the outer wall of the pin B pipe. The combination of the telescopic rod and the spring gives the buffer assembly a certain degree of self-adaptability, enabling it to automatically adjust the buffering force according to different pressures; simultaneously, through the elastic deformation of the spring, it can effectively absorb and disperse impact forces, protecting the connecting pipe and the pin B pipe from excessive impact.

[0008] Furthermore, the upper moving block has an elliptical rubber component at its upper end. This rubber component ensures that the inner wall of the connecting pipe is not damaged, while increasing the contact area with the inner wall of the connecting pipe, resulting in a more even distribution of force.

[0009] Furthermore, the lower end of the moving block is provided with a contour groove; the contour groove is set to fit the outer wall of the pin B tube. The contour groove increases the contact area with the outer wall of the pin B tube, disperses stress, and improves impact resistance.

[0010] Furthermore, the inner walls of the connecting pipe are provided with internal threads at both ends that mate with the external threads on the pin B pipe. The threaded connection ensures a stable connection between the pin A seat and the pin B pipe.

[0011] Furthermore, the plurality of buffer components are arranged in a ring within the connecting pipe. This ring-shaped arrangement ensures that the pin is effectively buffered when subjected to impacts in all radial directions, thus improving the buffering capacity.

[0012] Furthermore, several support plates are provided on the upper circumferential surface of the end of the pin A seat away from the pin B tube. The support plates provide more stable support for one end of the pin A seat, improving the pin's impact resistance.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. This utility model provides an impact-resistant adaptive buffer pin, which effectively buffers radial impacts through a ring-shaped buffer assembly distributed within the pin A seat.

[0015] 2. This utility model provides an impact-resistant adaptive buffer pin. The hydraulic oil reservoir inside the pin B tube is designed to disperse the pressure when the pin B tube is compressed, thus preventing excessive local pressure from causing damage to the local area.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0025] In this embodiment, as Figures 1 to 3 This utility model discloses an impact-resistant adaptive buffer pin, including a pin A seat 1 and a pin B tube 2. The pin A seat 1 has a connecting tube 11 in the middle. The pin B tube 2 is inserted into the connecting tube 11 to form a complete pin, and the two are connected by threads. Several sets of buffer components 3 are arranged radially inside the tube wall of the connecting tube 11. The two ends of the buffer components 3 respectively abut against the inner wall of the connecting tube 11 and the outer wall of the pin B tube 2. A liquid storage chamber 21 is provided inside the pin B tube 2. The liquid storage chamber 21 is arranged axially along the pin B tube 2 and has several branches radially along the pin B tube 2. Hydraulic oil is contained in the liquid storage chamber 21.

[0026] Specifically, anti-loosening measures can be taken at the threaded connection between pin B tube 2 and connecting tube 11, such as applying thread-locking adhesive to prevent the threads from loosening under vibration and impact.

[0027] Specifically, the hydraulic oil completely fills the reservoir 21. When subjected to impact, the hydraulic oil acts as a force transmission medium, transmitting pressure to the pin B tube 2 as a whole through hydrostatic transmission.

[0028] Specifically, the branch shape of the reservoir 21 is preferably circular; the radially arranged branches of the reservoir 21 can be curved as another preferred feature; the curved branches extend outward from the center to form a mesh structure to improve the hydrostatic transmission efficiency of the hydraulic oil.

[0029] In this embodiment, as Figure 3 and Figure 4 The buffer assembly 3 includes: an upper moving block 31, a lower moving block 32, a telescopic rod 33, and a spring 34; the upper moving block 31 and the lower moving block 32 are connected by the telescopic rod 33; the spring 34 is mounted on the telescopic rod 33, and its two ends abut against the upper moving block 31 and the lower moving block 32 respectively; the upper end of the upper moving block 31 abuts against the inner wall of the connecting pipe 11; the lower end of the lower moving block 32 abuts against the outer wall of the pin B pipe 2.

[0030] In particular, surface treatment of the telescopic rod 33 is optional, such as hard chrome plating or spraying a wear-resistant coating, to improve its wear resistance and corrosion resistance and extend its service life.

[0031] In this embodiment, as Figure 3 and Figure 4 The upper end of the upper moving block 31 is provided with an elliptical rubber part 311.

[0032] Specifically, it is preferable to coat the surface of the rubber part 311 with a wear-resistant coating or an anti-slip coating to improve its wear resistance and anti-slip performance and extend its service life.

[0033] In this embodiment, as Figure 3 and Figure 4 The lower end of the moving block 32 is provided with a contour groove 321; the contour groove 321 is set to fit the outer wall of the pin B tube 2.

[0034] Specifically, a rubber pad can be preferably installed in the contour groove 321 to provide additional cushioning and shock absorption.

[0035] In this embodiment, as Figures 1 to 3 The middle part of the pin B tube 2 and one end near the pin A seat 1 are provided with external threads; the two ends of the inner wall of the connecting tube 11 are provided with internal threads that cooperate with the external threads on the pin B tube 2.

[0036] Specifically, thread-locking adhesive can be applied to the external thread surface of pin B tube 2 to enhance the stability of pin B tube 2 after it is locked to pin A seat 1.

[0037] In this embodiment, as Figure 3 The plurality of buffer components 3 are arranged in a ring within the connecting pipe 11.

[0038] Specifically, the plurality of buffer components 3 are evenly distributed along the inner wall of the connecting pipe 11 to form a complete ring structure, ensuring that a certain buffering effect can be provided in all directions.

[0039] In this embodiment, as Figure 1 The pin A seat 1 is provided with several support plates 12 on the upper circumferential surface of the end away from the pin B tube 2.

[0040] Specifically, the support plate 12 is preferably set as a triangle, which can play a certain role in dispersing the force when the end face and circumference of the pin A seat 1 are subjected to impact force.

[0041] The working principle of the above embodiments is as follows:

[0042] This utility model discloses an impact-resistant adaptive buffer pin. When subjected to impact, the distance between the upper moving block 31 and the lower moving block 32 between the connecting pipe 11 and the pin B pipe 2 becomes shorter, causing the telescopic rod 33 to contract and compress the spring 34 at the same time. Simultaneously, the hydraulic oil in the reservoir 21 of the pin B pipe 2 is pressurized, and the concentrated input force is transmitted and distributed to the entire pin B pipe 2 through static pressure transmission, thereby achieving buffering and impact resistance.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
