Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mechanical buffer devices, specifically a novel guide rail buffer structure. Background Technology
[0002] Guide rail dampers are widely used in various mechanical equipment to reduce the impact force on moving parts and improve operational smoothness. However, in practical applications, traditional guide rail dampers often adopt mechanical or hydraulic structures, which have a slow response speed and are difficult to meet the precise control requirements under complex working conditions, resulting in problems such as low efficiency and inconvenience in operation.
[0003] A Chinese patent discloses a linkage structure for a three-section telescopic guide rail buffer (publication number CN108323970B). This design achieves linkage functionality through the meshing of gears and racks, enabling the guide rail to open upon pressure and automatically close. However, due to its reliance on a complex gear transmission system, wear or jamming may occur after long-term use, affecting the stability of the buffering performance. Furthermore, this structure requires high installation precision, increasing assembly difficulty and maintenance costs.
[0004] A Chinese patent also discloses a damping system for the collision of two inner doors of a sliding door (publication number CN106869664B). This design uses a buffer on a pulley block to work with a stopper hook to achieve a buffering and resetting function when the two doors close at any position. Although this solution solves the impact problem when the two doors close simultaneously, the connection method between the buffer and the stopper is relatively simple, making it difficult to adapt to the needs of doors of different weights and sizes, thus limiting its application range. Furthermore, the sliding stopper requires additional space to install the movable rail, which may increase the overall structural volume, making it unsuitable for scenarios with limited space.
[0005] The aforementioned prior art demonstrates that traditional guide rail dampers have limitations when dealing with complex operating conditions, particularly in terms of precise damping control and rapid response, which still require improvement. Therefore, this invention aims to provide a novel guide rail damper structure to overcome these shortcomings and meet the demands for efficient applications in varying environments. Utility Model Content
[0006] The purpose of this invention is to provide a novel guide rail buffer structure to solve the problems mentioned in the background art, such as slow response speed, high assembly accuracy requirements, poor adaptability, and insufficient stability of traditional guide rail buffers under complex working conditions.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A novel guide rail buffer structure includes a base, an elastic adjustment component, a sliding bracket, and a limiting device. The base is fixedly installed on one side of the guide rail. The sliding bracket is slidably connected to the base via a sliding groove. The elastic adjustment component is disposed inside the sliding bracket and movably cooperates with it. The limiting device is fixedly installed at the end of the sliding bracket and abuts against the base. Through the cooperation of the elastic adjustment component and the limiting device, the sliding stroke of the sliding bracket along the base and its buffering effect are controlled.
[0009] The upper surface of the base has a sliding groove running through its length. Multiple sets of positioning holes are symmetrically arranged on both sides of the sliding groove. Each set of positioning holes is fitted with a reinforcing rib to enhance the rigidity of the base. The two ends of the reinforcing rib are fixedly connected to the base by bolts. A wear-resistant coating made of polytetrafluoroethylene (PTFE) is applied to the bottom of the sliding groove to reduce friction between the sliding support and the sliding groove, thus extending its service life.
[0010] As a further embodiment of this invention, the elastic adjustment assembly includes a spring cylinder, an adjusting rod, and a pressure sensor. The spring cylinder is fixedly installed inside the sliding bracket. One end of the adjusting rod is inserted into the spring cylinder and contacts the compression spring inside the spring cylinder, while the other end is connected to the outer wall of the sliding bracket via a thread. By rotating the adjusting rod, the preload of the compression spring is changed, thereby adjusting the buffering effect. The pressure sensor is embedded in the bottom of the spring cylinder and is used to monitor the pressure value borne by the compression spring in real time and transmit the data to an external control system.
[0011] As a further improvement of this invention, multiple guide wheels are symmetrically arranged on both sides of the sliding bracket. Each guide wheel is rotatably connected to the sliding bracket via a bearing. The outer edge of the guide wheel is tightly fitted against the inner wall of the slide groove, ensuring smooth movement of the sliding bracket within the groove. A mounting plate for mounting external equipment is also provided on the top of the sliding bracket. The mounting plate is fixedly connected to the sliding bracket by bolts, and its surface has multiple mounting holes to facilitate adaptation to external equipment of different specifications.
[0012] As a further embodiment of this invention, the limiting device includes a limiting block, a buffer pad, and a locking mechanism. The limiting block is fixedly installed at the end of the sliding bracket, and the buffer pad is fixed to the front end face of the limiting block by adhesive bonding. The buffer pad is made of rubber material and is used to absorb the impact force generated when the sliding bracket collides with the base. The locking mechanism includes a locking bolt and a locking sleeve. The locking bolt passes through the limiting block and is threadedly connected to a positioning hole on the base. The locking sleeve is fitted onto the outer wall of the locking bolt. By rotating the locking sleeve, the locking bolt is tightly engaged with the positioning hole, thereby fixing the position of the sliding bracket.
[0013] As a further embodiment of this utility model, anti-detachment baffles are symmetrically arranged at both ends of the base. Each anti-detachment baffle is rotatably connected to the base via a hinge. A magnetic adsorption component is provided on the inner side of the anti-detachment baffle. When the anti-detachment baffle is closed, the magnetic adsorption component is attracted to the metal sheet on the surface of the base, preventing the sliding bracket from detaching from the groove of the base.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model, by incorporating an elastic adjustment component and utilizing the cooperation of an adjusting rod and a compression spring, can adjust the buffering effect according to actual needs, solving the problem of limited application range caused by the inability of traditional guide rail buffers to adapt to equipment of different weights and sizes. Simultaneously, the introduction of a pressure sensor enables real-time monitoring of the buffering process, providing data support for subsequent optimization.
[0016] 2. This utility model significantly reduces the friction between the sliding bracket and the sliding groove by setting a wear-resistant coating inside the base groove, which not only improves the smoothness of operation but also extends the service life of the overall structure. Furthermore, the design of the guide wheel further enhances the motion accuracy of the sliding bracket and avoids jamming.
[0017] 3. This utility model effectively reduces the impact force when the sliding bracket collides with the base through the buffer pad and locking mechanism in the limiting device. At the same time, the adjustability of the locking mechanism allows the sliding bracket to be fixed in any position, meeting the diverse needs under complex working conditions.
[0018] 4. This utility model, through the design of the anti-detachment baffle and the use of magnetic adsorption components, ensures the safety of the sliding bracket at its extreme position and avoids equipment damage or safety accidents caused by accidental detachment.
[0019] In summary, this utility model, through reasonable structural design and innovative technical means, solves the problems of slow response speed, high assembly precision requirements, and poor adaptability of traditional guide rail buffers under complex working conditions, and has high practicality and promotion value.

[0026] This utility model relates to a novel guide rail buffer structure, which achieves efficient and stable buffering function through the coordinated operation of multiple components. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Figure 1 As shown, the guide rail buffer structure includes a base 1, a sliding bracket 2, an elastic adjustment component 3, and a limiting device 4. The connection relationship, positional relationship, and mutual cooperation relationship between each component will be described one by one.
[0027] The base 1 is the foundation of the overall structure, and its upper surface has a groove 5 running through its length. The groove 5 is used to accommodate and guide the movement of the sliding support 2. Figure 2 As shown, multiple sets of positioning holes 6 are symmetrically arranged on both sides of the slide groove 5. Reinforcing ribs 7 are embedded within the positioning holes 6, and both ends of the reinforcing ribs 7 are fixedly connected to the base 1 by bolts, thereby enhancing the overall rigidity of the base 1. A wear-resistant coating 8 made of polytetrafluoroethylene is coated on the bottom of the slide groove 5. This coating directly covers the metal surface of the slide groove 5, reducing friction during the movement of the sliding bracket 2. Anti-detachment baffles 17 are symmetrically installed at both ends of the base 1. The anti-detachment baffles 17 are rotatably connected to the base 1 via hinges, and magnetic adsorption components are provided on their inner sides. When the anti-detachment baffles 17 are closed, the magnetic adsorption components are adsorbed onto the metal sheet on the surface of the base 1, preventing the sliding bracket 2 from accidentally detaching from the slide groove 5.
[0028] The sliding bracket 2 is slidably connected to the base 1 via a sliding groove 5. Multiple guide wheels 12 are symmetrically arranged on both sides of the bracket, each guide wheel 12 being rotatably connected to the sliding bracket 2 via a bearing. The outer edge of the guide wheel 12 is in close contact with the inner wall of the sliding groove 5, ensuring smooth movement of the sliding bracket 2 within the groove 5. A mounting plate 13 is provided on the top of the sliding bracket 2, and the mounting plate 13 is fixedly connected to the sliding bracket 2 by bolts. Multiple mounting holes are provided on its surface to facilitate adaptation to external equipment of different specifications. An elastic adjustment assembly 3 is provided inside the sliding bracket 2, which includes a spring cylinder 9, an adjusting rod 10, and a pressure sensor 11. Figure 3As shown, the spring cylinder 9 is fixedly installed inside the sliding bracket 2. One end of the adjusting rod 10 is inserted into the spring cylinder 9 and contacts the compression spring, while the other end is connected to the outer wall of the sliding bracket 2 via a thread. Rotating the adjusting rod 10 changes the preload of the compression spring, thereby adjusting the buffering effect. A pressure sensor 11 is embedded in the bottom of the spring cylinder 9, and its signal line passes through a pre-reserved channel in the sliding bracket 2 to connect to an external control system for real-time monitoring of the pressure value borne by the compression spring.
[0029] The limiting device 4 is installed at the end of the sliding bracket 2, and includes a limiting block 14, a buffer pad 15, and a locking mechanism 16. Figure 2 As shown, the limiting block 14 is fixedly installed at the end of the sliding bracket 2, and the buffer pad 15 is fixed to the front end face of the limiting block 14 by adhesive. The buffer pad 15 is made of rubber material with uniform thickness and smooth surface, which can absorb the impact force generated when the sliding bracket 2 collides with the base 1. The locking mechanism 16 includes a locking bolt and a locking sleeve. The locking bolt passes through the limiting block 14 and is threadedly connected to the positioning hole 6 on the base 1. The locking sleeve is sleeved on the outer wall of the locking bolt. By rotating the locking sleeve, the locking bolt is tightly engaged with the positioning hole 6, thereby fixing the position of the sliding bracket 2.
[0030] In practical applications, the working process of this guide rail buffer structure is as follows: First, the base 1 is fixedly installed on one side of the guide rail. The sliding bracket 2 is slidably connected to the base 1 through the slide groove 5. The movement of the sliding bracket 2 is guided by the guide wheel 12, which rolls along the inner wall of the slide groove 5 to ensure smooth movement. The top mounting plate 13 of the sliding bracket 2 is used to fix external equipment. The weight of the external equipment is transmitted to the elastic adjustment component 3 through the sliding bracket 2. The adjusting rod 10 in the elastic adjustment component 3 adjusts the preload of the compression spring by rotation to accommodate external equipment of different weights and sizes. When the sliding bracket 2 moves to its limit position in the slide groove 5, the buffer pad 15 of the limiting device 4 contacts the base 1 to absorb the impact force. At the same time, the locking mechanism 16 fixes the sliding bracket 2 in the designated position through the cooperation of the locking bolt and the locking sleeve. During this process, the pressure sensor 11 monitors the pressure value of the compression spring in real time and transmits the data to the external control system to provide a basis for subsequent optimization.
[0031] Through the above structural design, the guide rail buffer of this utility model can achieve rapid response and high-precision assembly under complex working conditions, while possessing strong adaptability and stability. The reinforcing ribs 7 and wear-resistant coating 8 of the base 1 significantly improve the rigidity and service life of the overall structure. The design of the guide wheel 12 avoids jamming of the sliding bracket 2 during movement, while the buffer pad 15 and locking mechanism 16 of the limiting device 4 effectively reduce collision impact and achieve flexible position fixation. The design of the anti-detachment baffle 17 further enhances the safety of the sliding bracket 2 at extreme positions, avoiding equipment damage or safety accidents caused by accidental detachment.
[0032] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.
[0033] In a guide rail system of a mechanical device, this novel guide rail damper structure is used to control the movement of sliding components and reduce impact forces. First, a base 1 is bolted to one side of the equipment guide rail. A groove 5 on the base 1 accommodates a sliding bracket 2 and provides a guide path for the movement of the sliding bracket 2. For example... Figure 2 As shown, the positioning holes 6 on both sides of the slide groove 5 are fitted with reinforcing ribs 7, which are fastened to the base 1 by bolts, thereby significantly enhancing the overall rigidity of the base 1 and ensuring that it is not easily deformed during long-term use. At the same time, the polytetrafluoroethylene wear-resistant coating 8 applied to the bottom of the slide groove 5 directly covers the metal surface, reducing the friction generated when the sliding bracket 2 moves in the slide groove 5, making the sliding smoother and extending its service life.
[0034] Subsequently, the sliding bracket 2 is connected to the slide groove 5 via guide wheels 12 symmetrically arranged on both sides. The guide wheels 12 are rotatably connected to the sliding bracket 2 via bearings, and their outer edges are tightly fitted against the inner wall of the slide groove 5, such as... Figure 4 As shown. This design not only ensures the smooth movement of the sliding bracket 2 within the slide groove 5, but also effectively avoids operational problems caused by friction or jamming. The mounting plate 13 on the top of the sliding bracket 2 is fixedly connected to external equipment by bolts. The multiple mounting holes on the surface of the mounting plate 13 can be flexibly adapted to meet the needs of different equipment specifications, thereby satisfying diverse assembly requirements.
[0035] When an external device applies a load, the sliding bracket 2 transfers the load to the elastic adjustment component 3. For example... Figure 3As shown, the spring cylinder 9 in the elastic adjustment assembly 3 is fixedly installed inside the sliding bracket 2. One end of the adjusting rod 10 is inserted into the spring cylinder 9 and contacts the internal compression spring, while the other end is connected to the outer wall of the sliding bracket 2 via a thread. By rotating the adjusting rod 10, the preload of the compression spring can be changed, thereby adjusting the buffering effect to adapt to external equipment of different weights and sizes. The pressure sensor 11 is embedded in the bottom of the spring cylinder 9, which monitors the pressure value borne by the compression spring in real time and transmits the data to the external control system, providing a basis for subsequent optimization. This process realizes dynamic control of the buffering effect, solving the problem that traditional guide rail buffers are difficult to adapt to complex working conditions.
[0036] When the sliding bracket 2 moves to its limit position along the slide groove 5, the limiting device 4 activates. For example... Figure 2 As shown, the limiting block 14 is fixedly installed at the end of the sliding bracket 2, and a rubber buffer pad 15 is bonded to its front end. When the sliding bracket 2 contacts the base 1, the buffer pad 15 absorbs the impact force generated by the collision, effectively reducing the impact on the equipment. The locking mechanism 16 includes a locking bolt and a locking sleeve. The locking bolt passes through the limiting block 14 and is threadedly connected to the positioning hole 6 on the base 1. By rotating the locking sleeve, the locking bolt is tightly engaged with the positioning hole 6, thereby fixing the sliding bracket 2 in the designated position. This design not only achieves flexible positioning of the sliding bracket 2, but also significantly improves the adaptability of the equipment under complex working conditions.
[0037] Furthermore, the anti-detachment baffles 17, symmetrically installed at both ends of the base 1, are rotatably connected to the base 1 via hinges. Magnetic adsorption components on their inner sides adhere to the metal sheet on the surface of the base 1 when closed, preventing the sliding bracket 2 from accidentally detaching from the slide groove 5. This safety design further enhances the safety of the sliding bracket 2 at its extreme positions, avoiding equipment damage or safety accidents caused by accidental detachment.
[0038] As can be seen from the above steps, the guide rail buffer structure of this utility model can effectively meet the buffering needs under complex working conditions in practical applications. The reinforcing ribs 7 and wear-resistant coating 8 of the base 1 improve the rigidity and service life of the overall structure; the design of the guide wheel 12 ensures the smooth movement of the sliding bracket 2; the elastic adjustment component 3 achieves dynamic adjustment of the buffering effect through the synergistic action of the adjustment rod 10 and the pressure sensor 11; the buffer pad 15 and locking mechanism 16 of the limiting device 4 effectively reduce the impact force and achieve flexible position fixation; the design of the anti-detachment baffle 17 further enhances safety. These technical means work together to enable this utility model to achieve efficient and stable buffering function in various application scenarios, and has strong adaptability and stability.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
