Description
Technical Field
[0001] This utility model relates to the field of buffer technology, specifically to an integrated bidirectional buffer with an aluminum shell and slide groove. Background Technology
[0002] Referring to the technical solution disclosed in publication number CN215671706U, the bidirectional buffer includes a bidirectional buffer body, which comprises a steel shell, plastic clips, and a buffering mechanism. The plastic clips are composed of two plastic shells, a first plastic shell and a second plastic shell, which are placed inside the steel shell and interlocked. The buffering mechanism includes a damping cylinder, with its fixed end inserted into a first slider and its telescopic end inserted into a second slider. A buffer spring is installed between the first and second sliders, and when the first and second sliders are respectively placed at both ends of the plastic clips, the distance between the first and second sliders is the same as the length of the buffer spring when relaxed. The first and second sliders are slidably installed on the inner ends of the first and second plastic shells, respectively. Sliding posts are also fixedly connected to the first and second sliders, with both ends of the sliding posts inserted into the sliding grooves of the first and second plastic shells, respectively. The above structure provides sliding grooves in the first and second plastic shells, allowing the first and second sliders to buffer along the guide grooves.
[0003] However, since the chute is entirely set on the plastic shell, and the plastic shell and the chute are quite long, they are prone to injection deformation and shrinkage during the injection molding process, resulting in a poor yield rate and high production costs. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an integrated bidirectional buffer with an aluminum shell and slide groove.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] An integrated bidirectional buffer with an aluminum shell and sliding groove includes a metal shell, a sliding hook block, a first end seat and a second end seat located at the left and right ends of the metal shell, respectively. The metal shell has a buffer cavity and a sliding port. The lower end of the sliding hook block extends into the buffer cavity from the sliding port. The buffer cavity is provided with a damping cylinder and a buffer spring connected to the sliding hook block. The buffer cavity is characterized by: a straight sliding groove extending from left to right on the cavity wall; mounting ports on the left and right ends of the buffer cavity; both the first end seat and the second end seat include a seat body fixed in the mounting port; a sliding groove is provided on the seat body of the first end seat and / or the second end seat; the sliding groove communicates with the straight sliding groove and forms a guide groove; and a sliding pin is provided on the sliding hook block that slides in the guide groove.
[0007] In this invention, two sliding hook blocks are distributed left and right, and the damping cylinder and buffer spring are arranged from top to bottom between the two sliding hook blocks. The two ends of the damping cylinder and the two ends of the buffer spring are respectively connected to the two sliding hook blocks.
[0008] In this invention, a limiting block is provided in the buffer cavity between two sliding hook blocks, and both ends of the limiting block are fixedly installed on the metal shell.
[0009] In this utility model, the front and rear walls of the buffer cavity are provided with positioning slots, which extend from left to right. The front and rear ends of the limiting block are provided with isolation positioning parts that are inserted into the positioning slots. The isolation positioning parts are fixedly connected to the metal shell by isolation bolts.
[0010] In this utility model, the damping cylinder and the buffer spring are located at the upper and lower ends of the limiting block, respectively. The upper end of the limiting block is provided with a damping avoidance groove for avoiding the damping cylinder, and the lower end is provided with a spring avoidance groove for avoiding the buffer spring.
[0011] In this utility model, the front and rear walls of the buffer cavity are provided with the linear sliding grooves, and the front and rear sides of the seat are provided with the sliding grooves. The two ends of each linear sliding groove are respectively connected to a sliding groove on the first end seat and a sliding groove on the second end seat. The front and rear ends of the sliding hook block are provided with two sliding columns.
[0012] In this utility model, the first end seat further includes a first connecting block integrally formed and connected to the seat body. The first connecting block abuts against the end of the metal shell, and a first guide wheel device is fitted on the first end seat.
[0013] In this utility model, the second end seat further includes a second connecting block integrally formed and connected to the seat body. The second connecting block abuts against the end of the metal shell, and a second guide wheel device is installed on the second connecting block.
[0014] In this utility model, the base is provided with a positioning insert, which is inserted into one end of the positioning slot.
[0015] In this invention, the seat body is provided with a seat clearance groove for the sliding hook block, so that the sliding column of the sliding hook block can slide into the groove.
[0016] The beneficial effects of this utility model are as follows: First, a straight groove is provided on the buffer cavity wall of the metal shell, and then a groove is provided on the base. When the connecting base is installed in the mounting socket, the groove and the straight groove are connected to form a guide groove.

[0028] Reference Figure 1-6 An integrated bidirectional buffer with an aluminum shell and sliding groove includes a metal shell 1, two sliding hook blocks 2, a first end seat 3 and a second end seat 4 located at the left and right ends of the metal shell 1, respectively. The metal shell 1 has a buffer cavity 11 located inside it and a sliding port 12 located at its top. The lower end of the sliding hook block 2 extends into the buffer cavity 11 from the sliding port 12. The buffer cavity 11 is provided with a damping cylinder 5 and a buffer spring 6 connected to the sliding hook block 2. The cavity wall of the buffer cavity 11 is provided with a straight sliding groove 13 extending from left to right. The left and right ends of the buffer cavity 11 are provided with mounting sockets 14 penetrating the metal shell 1. The first end seat 3 and the second end seat 4 both include a seat body 100 installed and fixed in the mounting socket 14. The seat body 100 of the first end seat 3 and / or the second end seat 4 is provided with a sliding groove 101. The sliding groove 101 communicates with the straight sliding groove 13 and forms a guide groove. The sliding hook block 2 is provided with a sliding post 21 that slides in the guide groove.
[0029] This invention first provides a linear groove 13 on the wall of the buffer cavity 11 of the metal shell 1, and then provides a groove 101 on the seat 100. When the connecting seat 100 is installed in the mounting socket 14, the groove 101 communicates with the linear groove 13 and forms a guide groove. In this way, the linear groove 13 of the guide groove is set on the metal shell 1. By utilizing the rigidity and stability of the metal shell 1, not only are the problems caused by injection molding shrinkage or thermal deformation when the guide groove is completely set on the plastic shell in the traditional way solved, but the structural stability of the guide groove is also guaranteed. This provides a stable guiding effect for the sliding hook block 2 and enhances the stability of the bidirectional buffer.
[0030] In this embodiment, the metal shell 1 is made of aluminum profile, which is lightweight, has good structural strength, and stable processing accuracy, so that structures such as the linear groove 13 and the positioning slot 15 can be formed simultaneously during the extrusion production of aluminum profile; the first end seat 3 and the second end seat 4 are both made of PA66 injection molding, which has excellent properties such as wear resistance, heat resistance and impact resistance.
[0031] In this embodiment, the lower end of the chute 101 is a vertically arranged straight segment, and the upper end is a transition arc segment that bends upward toward the straight chute 13. The upper end of the transition arc segment is connected to the straight chute 13, and the lower end is connected to the straight segment. The transition arc segment facilitates the sliding column 21 to slide into and out of the straight segment.
[0032] In this embodiment, two sliding hook blocks 2 are arranged left and right, and the damping cylinder 5 and the buffer spring 6 are arranged from top to bottom between the two sliding hook blocks 2. Both ends of the damping cylinder 5 and both ends of the buffer spring 6 are respectively connected to the two sliding hook blocks 2. Further, each end of the damping cylinder 5 is provided with a damping latch 51, and the sliding hook block 2 is provided with a damping latch position 22 that snaps into the damping latch 51. The damping latch 51 is fastened into the damping latch position 22 to connect the damping cylinder 5 to the sliding hook block 2. The buffer spring 6 is a tension spring, and both ends of the buffer spring 6 are provided with spring latches 61. The sliding hook block 2 is provided with spring latch positions 23 that snap into the spring latches 61. The spring latches 61 at both ends of the buffer spring 6 are respectively fastened into the spring latch positions 23 of the two sliding hook blocks 2 to connect the buffer spring 6 to the sliding hook blocks 2. This structure allows the sliding hook block 2 to snap into the damping cylinder 5 and the buffer spring 6, facilitating their assembly and installation.
[0033] In a preferred embodiment, the buffer cavity 11 is provided with a limiting block 7 located between the two sliding hook blocks 2. The front and rear ends of the limiting block 7 are fixedly installed on the metal shell 1, thereby strengthening the structural stability of the metal shell 1 and avoiding the risk of the sliding hook blocks 2 falling off due to the expansion, contraction and deformation of the metal shell 1. Moreover, since the limiting block 7 is located between the two sliding hook blocks 2, it can limit the movement stroke of the sliding hook blocks 2. That is, during the movement and buffering process of the sliding hook blocks 2, when the sliding hook blocks 2 are blocked by the limiting block 7 and cannot continue to move, the working stroke of both the sliding hook blocks 2 and the damping cylinder 5 is limited, avoiding the damping cylinder 5 from bursting and failing due to the strong impact when closing the door.
[0034] In this embodiment, in order to improve the installation quality of the limiting block 7, the front and rear walls of the buffer cavity 11 are provided with positioning slots 15, which extend from left to right. The front and rear ends of the limiting block 7 are provided with isolation positioning parts 71 that are inserted into the positioning slots 15. The isolation positioning parts 71 are fixedly connected to the metal shell 1 by isolation bolts 72. The screw end of the isolation bolt 72 passes through the mating through hole on the metal shell 1 and is threaded into the isolation screw hole on the isolation positioning part 71, thereby completing the combined installation between the limiting block 7 and the metal shell 1.
[0035] In this embodiment, the damping cylinder 5 and the buffer spring 6 are located at the upper and lower ends of the limiting block 7, respectively. The upper end of the limiting block 7 is provided with a damping avoidance groove 73 for avoiding the damping cylinder 5, and the lower end is provided with a spring avoidance groove 74 for avoiding the buffer spring 6, thereby reducing the space occupied by the limiting block 7 in the buffer cavity 11, so as to make the structure of the buffer more compact.
[0036] In a preferred embodiment, the front and rear walls of the buffer cavity 11 are provided with linear grooves 13, and the front and rear sides of the seat body 100 are provided with grooves 101. The two ends of each linear groove 13 are respectively connected to a groove 101 on the first end seat 3 and a groove 101 on the second end seat 4. The front and rear ends of the sliding hook block 2 are provided with two sliding pillars 21.
[0037] In this embodiment, the first end seat 3 further includes a first connecting block 31 integrally formed and connected to the seat body 100. The first connecting block 31 abuts against the end of the metal shell 1, thereby limiting the depth of the seat body 100 of the first end seat 3 inserted into the buffer cavity 11. Further, the first end seat 3 is provided with a connecting slot 32. The first end seat 3 is coupled with a first guide wheel device 8 through the connecting slot 32. The first guide wheel device 8 includes a first wheel seat 81, two first wheel axles 82, and four first rollers 83. One end of the first wheel seat 81 is inserted into the connecting slot 32 and simultaneously connected to the first end seat 3 and the metal shell 1 through a first fastener 84. The first fastener 84 is a rivet riveted to the first wheel seat 81, the first end seat 3, and the metal shell 1. The two first wheel axles 82 are arranged from left to right on the first wheel seat 81. The two ends of the first wheel axles 82 are respectively provided with first rollers 83 located on both sides of the first wheel seat 81. The first wheel seat 81 is provided with a hanging hole 811 for connecting a door panel.
[0038] In this embodiment, the second end seat 4 further includes a second connecting block 41 integrally formed and connected to the seat body 100. The second connecting block 41 abuts against the end of the metal shell 1, thereby limiting the depth to which the seat body 100 of the second end seat 4 is inserted into the buffer cavity 11. A second guide wheel device 9 is mounted on the second connecting block 41. The second guide wheel device 9 includes a second wheel axle 91 and two second rollers 92. The second wheel axle 91 is mounted on the second connecting block 41, and the second rollers 92 are mounted on the second wheel axle 91 and are respectively located on both sides of the second connecting block 41. In addition, the seat body 100 of the second end seat 4 is combined and connected to the metal shell 1 by a second fastener 93, which is a rivet riveted to the second end seat 4 and the metal shell 1.
[0039] In this embodiment, the base 100 is provided with a positioning insert 102, which is inserted into one end of the positioning slot 15 to enhance the mass of the first end seat 3 and the second end seat 4 mounted on the metal shell 1.
[0040] In this embodiment, the seat 100 is provided with a seat avoidance groove 103 for avoiding the sliding hook block 2, so that the sliding column 21 of the sliding hook block 2 can slide into the sliding groove 101.
[0041] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
