[0004] However, when the bolts are used to fasten the product to be assembled, not only a large number of turns are required to reach the fixed effect, but also rust is prone to occur between the bolts and the nuts with the increase of the use time, and it is difficult to screw or not to reach the position when the bolts are fastened, which is prone to occur, and the assembly process of the product to be assembled is inconvenient, and the processing time of the product is greatly wasted, and the production progress is delayed. CONTENT OF THE UTILITY MODEL
[0005] In view of the deficiencies in the related art, the application provides a shock-absorbing bracket, which clamps and fixes the product to be assembled through the rotating connection of the load-bearing plate assembly and the clamping arm and the cooperation of the fixed beam and the guide hole, deletes the operation of fastening with bolts, saves the assembly time and speeds up the production progress.
[0006] The application provides a shock-absorbing bracket, which comprises:
[0007] a main frame, which is hollow inside and has at least one open end, and the open end of the main frame is used for loading or unloading a product to be assembled;
[0008] at least two fixed beams, which are oppositely arranged in the main frame and located at one end close to the open end of the main frame;
[0009] a load-bearing plate assembly, which is movably arranged in the main frame and used for moving away from or close to the open end of the main frame along with the product to be assembled;
[0010] at least two clamping assemblies, which are rotatably arranged on the load-bearing plate assembly, and each clamping assembly comprises a clamping arm, a guide hole is arranged on the clamping arm, the fixed beam passes through the guide hole, one end of each clamping arm is rotatably arranged on the load-bearing plate assembly, and the other end of each clamping arm is clamped or released on the product to be assembled through the cooperation of the guide hole and the fixed beam.
[0011] In some embodiments, the load-bearing plate assembly comprises:
[0012] a load-bearing member, the load-bearing member having a maximum cross-section at an end thereof closer to the opening of the main frame, the clamping arm being pivotally connected to the load-bearing member at the end thereof closer to the opening of the main frame;
[0013] a resilient member, the resilient member being disposed at an end of the load-bearing member further away from the opening of the main frame, the resilient member being located between the load-bearing member and the main frame.
[0014] In some embodiments, the clamping arm is closer to the longitudinal centerline of the main frame at the pivotally connected end of the clamping arm to the load-bearing member than at the end of the clamping arm further away from the load-bearing plate assembly.
[0015] In some embodiments, the clamping assembly comprises:
[0016] an extension arm, the extension arm being disposed at an end of the clamping arm further away from the load-bearing plate assembly;
[0017] a clamp, the clamp being disposed at an end of the extension arm further away from the clamping arm.

[0040] Reference Appendix Figures 1 to 5 , Figure 1 This is a perspective view of the shock-absorbing bracket of this application; Figure 2 This is a front view of the shock-absorbing bracket of this application; Figure 3 This is a top view of the shock-absorbing bracket of this application; Figure 4 This is a perspective view of the clamping assembly 400 of the shock-absorbing bracket of this application; Figure 5 This is a schematic diagram of the connection structure between the main frame 100 and the fixed beam 200 of the shock-absorbing bracket of this application; the specific embodiments are described below with reference to the above-mentioned drawings.
[0041] Reference Appendix Figure 1 and Figure 2This application provides a shock-absorbing bracket, including a main frame 100, at least two fixed beams 200, a load-bearing plate assembly 300, and at least two clamping assemblies 400. The main frame 100 is hollow internally and open at least one end. The opening of the main frame 100 is used to load or unload a product to be assembled. The two fixed beams 200 are disposed opposite each other within the main frame 100 and located near the opening of the main frame 100. The load-bearing plate assembly 300 is movably disposed within the main frame 100 and is used to adjust the load-bearing plate assembly 400 according to the load-bearing capacity of the main frame. The product to be assembled moves toward the end away from or toward the opening of the main frame 100. The two clamping components 400 are rotatably mounted on the load-bearing plate assembly 300. The clamping components 400 include clamping arms 401, and guide holes 4011 are provided on the clamping arms 401. The fixed beam 200 passes through the guide holes 4011. One end of the two clamping arms 401 is rotatably mounted on the load-bearing plate assembly 300. The other end of the two clamping arms 401 cooperates with the fixed beam 200 through the guide holes 4011 to clamp or release the product to be assembled.
[0042] When the product to be assembled is inserted into the main frame 100 through the opening, the weight of the product to be assembled pushes the load-bearing plate assembly 300 to move away from the opening of the main frame 100. At the same time, one end of the two clamping arms 401 rotates relative to the load-bearing plate assembly 300, and the other end of the two clamping arms 401 moves towards each other under the guidance of the fixed beam 200 and the guide hole 4011, thereby clamping and fixing the product to be assembled between the two clamping arms 401.
[0043] Reference Appendix Figure 1 , Figure 2 , Figure 3 as well as Figure 5 In some embodiments, the main frame 100 is hollow inside and open at least one end, and the opening of the main frame 100 is used to load or unload a product to be assembled; the main frame 100 is also provided with four weight reduction holes on the side wall, and the four weight reduction holes are arranged around one end of the opening of the main frame 100.
[0044] Specifically, the main frame 100 is a rectangular component with a hollow interior and five of its six sides having holes or openings. This reduces the weight of the main frame 100, making it easier to move for assembly. It also allows operators to easily observe the interior of the main frame 100 from the outside, facilitating assembly.
[0045] The remaining side of the six sides of the main frame 100 serves as the bottom wall, and the opening or hole relative to the bottom wall serves as the top surface for loading or unloading products to be assembled.
[0046] Reference Appendix Figure 1 , Figure 3 as well as Figure 5In some embodiments, two fixed beams 200 are disposed opposite to each other within the main frame 100 and located at one end near the opening of the main frame 100; the two ends of the fixed beams 200 are respectively fixed between two adjacent side walls of the main frame 100.
[0047] Specifically, the fixed beam 200 is located inside the main frame 100 and between two adjacent side walls of the main frame 100. The fixed beam 200 and the two adjacent side walls of the main frame 100 together form a stable triangular structure, which is used to enhance the stability of the main frame 100. The central area of the triangular structure supports the clamping arm 401 to pass through, thereby restricting the horizontal displacement of the clamping arm 401.
[0048] Reference Appendix Figure 1 In some embodiments, the rotatable connection between the clamping arm 401 and the load-bearing member 301 is closer to the longitudinal centerline of the main frame 100 relative to the fixed beam 200.
[0049] Specifically, by passing the fixed beam 200 through the guide hole 4011 on the clamping arm 401, the clamping arm 401 is displaced in the longitudinal direction relative to the fixed beam 200 when rotating relative to the load-bearing component 301. At the same time, since the rotating connection between the clamping arm 401 and the load-bearing component 301 is closer to the longitudinal centerline of the main frame 100 relative to the fixed beam 200, the clamping arm 401 also rotates relative to the fixed beam 200 through the guide hole 4011 when rotating relative to the load-bearing plate assembly 300. This causes the angle between the clamping arm 401 and the longitudinal centerline of the main frame 100 to increase or decrease, thereby causing the end of the clamping arm 401 away from the load-bearing plate to move relative to the longitudinal centerline of the main frame 100 in a direction away from or closer to the longitudinal centerline of the main frame 100, so as to unload or clamp the product to be assembled.
[0050] It should be noted that the number of fixed beams 200 should be set to at least two according to the actual situation. The two fixed beams 200 are arranged opposite each other to guide the two clamping components 400 to clamp the product to be assembled. For spherical products with smooth surfaces to be assembled, the number of fixed beams 200 is set to three. The three fixed beams 200 are arranged at equal intervals to guide the three clamping components 400 to clamp the product to be assembled. In some embodiments, the number of fixed beams 200 is set to four. The four fixed beams 200 are arranged at equal intervals to guide the four clamping components 400 to stably clamp the product to be assembled.
[0051] Reference Appendix Figures 1 to 3In some embodiments, the load-bearing plate assembly 300 is movably disposed within the main frame 100. The load-bearing plate assembly 300 is used to move away from or towards the opening of the main frame 100 as the product to be assembled moves. The load-bearing plate assembly 300 includes a load-bearing member 301 and an elastic member 302. The maximum cross-section of the load-bearing member 301 faces the opening of the main frame 100. The clamping arm 401 is rotatably disposed at the end of the load-bearing member 301 near the opening of the main frame 100. The elastic member 302 is disposed at the end of the load-bearing member 301 away from the opening of the main frame 100. The elastic member 302 is located between the load-bearing member 301 and the main frame 100.
[0052] Specifically, the load-bearing component 301 is used to support the product to be assembled when it is installed inside the main frame 100, moving the product away from the opening of the main frame 100. At the same time, the elastic component 302 is compressed to store elastic potential energy and provides a certain supporting force to the load-bearing component 301 to counteract the gravity of the product to be assembled, thereby achieving the technical effect of shock absorption and buffering.
[0053] Since the load-bearing component 301 is rotatably connected to the clamping arm 401, and the clamping arm 401 is restricted by the cooperation between the guide hole 4011 and the fixed beam 200, although the load-bearing component 301 is movably located within the main frame 100, its movement direction is mainly along the longitudinal centerline of the main frame 100, away from or close to the end of the opening of the main frame 100; the elastic component 302 includes, but is not limited to, springs, tension springs, and rubber. The elastic coefficient of the elastic component 302 should be set according to the actual situation to avoid the supporting force being too small, causing the weight of the product to be assembled to cause impact damage to the main frame 100, or the supporting force being too large, failing to provide shock absorption and buffering function.
[0054] Reference Appendix Figures 1 to 4 In some embodiments, at least two clamping assemblies 400 are rotatably mounted on the load-bearing plate assembly 300. Each clamping assembly 400 includes a clamping arm 401, an extension arm 402, and a clamp 403. The clamping arm 401 has a guide hole 4011, through which the fixing beam 200 passes. One end of the two clamping arms 401 is rotatably mounted on the load-bearing plate assembly 300, and the other end of the two clamping arms 401 engages with the fixing beam 200 through the guide hole 4011 to clamp or release the product to be assembled. The extension arm 402 is located at the end of the clamping arm 401 away from the load-bearing plate assembly 300. The clamp 403 is located at the end of the extension arm 402 away from the clamping arm 401.
[0055] Specifically, the guide hole 4011 is provided on the clamping arm 401 and extends along the length of the clamping arm 401. The fixing beam 200 passes through the guide hole 4011 to restrict the movement of the clamping arm 401 in the horizontal direction and guides the clamping arm 401 to move relative to the fixing beam 200 in the longitudinal direction.
[0056] The clamping arm 401, through the cooperation of the fixed beam 200 and the guide hole 4011, transmits the rotation of one end relative to the load-bearing member 301 to the other end, thereby driving the extension arm 402 and the clamp 403 at the other end to move away from or towards the longitudinal centerline of the main frame 100.
[0057] The extension arm 402 is located at the end of the clamping arm 401 away from the load-bearing member 301. It is used to convert the arc movement of the clamping arm 401 away from the load-bearing member 301 into horizontal movement, so as to correct the clamping angle of the clamping arm 401 and clamp and fix the product to be assembled.
[0058] The clamp 403 is located at the end of the extension arm 402 away from the clamping arm 401, and is used to increase the contact area with the product to be assembled, thereby maintaining clamping stability.
[0059] Reference Appendix Figures 1 to 4 In some embodiments, the extension arm 402 is tilted toward the longitudinal centerline of the main frame 100 to achieve the technical effect of amplifying the rotation angle of the clamping arm 401 relative to the load-bearing member 301, thereby reducing the travel of the end of the clamping arm 401 away from the load-bearing member 301, and thus quickly clamping the product to be assembled.
[0060] It should be noted that, based on the shape and size of the product to be assembled, the operator should adjust the extension arm 402 according to the actual situation. When the size of the product to be assembled is small, the tilt angle of the extension arm should be increased to reduce the stroke; or, when the size of the product to be assembled is large, the tilt angle of the extension arm should be decreased to increase the stroke.
[0061] Reference Appendix Figure 1 and Figure 4 In some embodiments, the clamping assembly 400 further includes a buffer 404, which is fixed on the clamp 403 and close to one end of the product to be assembled. The buffer 404 includes, but is not limited to, felt or rubber. The buffer 404 is used to increase the friction between the clamp 403 and the product to be assembled, prevent slippage, and protect the product to be assembled, preventing the movement of the clamp 403 from scratching it.
[0062] In some embodiments, the minimum distance between the two fixed beams 200 is not less than the maximum outer diameter of the load-bearing member 301. The longitudinal movement of the load-bearing member 301 is restricted by the two fixed beams 200 arranged opposite to each other, so as to avoid the situation where the elastic member 302 releases its maximum elastic potential energy to push the load-bearing member 301 out of the main frame 100 after unloading the product to be assembled from the main frame 100, thus ensuring the efficiency and safety of the assembly process.
[0063] In some embodiments, the minimum inner diameter of the guide hole 4011 is not less than the maximum outer diameter of the fixed beam 200, even if the minimum inner diameter of the guide hole 4011 is greater than or equal to the maximum outer diameter of the fixed beam 200, in order to improve the relative flexibility between the clamping arm 401 and the fixed beam 200, thereby avoiding the situation where the relative movement is not smooth enough and the assembly efficiency is reduced.
[0064] When the shock-absorbing bracket of this application clamps the product to be assembled, the product to be assembled is lifted by a lifting device so that the bottom end of the product to be assembled first enters the main frame 100 and contacts the load-bearing component 301. The load-bearing component 301 moves away from the opening of the main frame 100 based on the weight of the product to be assembled, thereby compressing the elastic component 302. During the process of the product to be assembled entering the main frame 100, the clamping component 400 rotates relative to the load-bearing component 301, and with the cooperation of the guide hole 4011 and the fixed beam 200, the end of the clamping arm 401 away from the load-bearing component 301 drives the extension wall and the clamp 403 to gradually move towards the longitudinal center line of the main frame 100, thereby completing the clamping and fixing of the product to be assembled.
[0065] When unloading the product to be assembled, the product is lifted by a lifting device so that the top of the product extends out of the main frame 100 first. Based on the reduction of the downward gravity of the product, the elastic element 302 releases its elastic force to push the load-bearing element 301 to move towards the end of the opening of the main frame 100. During the process of the product extending out of the main frame 100, the clamping assembly 400 rotates relative to the load-bearing element 301. With the cooperation of the guide hole 4011 and the fixed beam 200, the end of the clamping arm 401 away from the load-bearing element 301 drives the extension wall and the clamp 403 to gradually move away from the longitudinal centerline of the main frame 100, thereby releasing the clamping of the product to be assembled.
[0066] This application provides a shock-absorbing bracket. When the product to be assembled is inserted into the main frame 100 through the opening, the weight of the product pushes the load-bearing plate assembly 300 to move away from the opening of the main frame 100. At the same time, one end of the two clamping arms 401 rotates relative to the load-bearing plate assembly 300, and the other end of the two clamping arms 401 moves towards each other under the guidance of the fixed beam 200 and the guide hole 4011. This clamps and fixes the product to be assembled between the two clamping arms 401, eliminating the need for bolt fastening, saving assembly time, and speeding up production. Through the cooperation of the elastic element 302 and the load-bearing element 301, the clamping arms 401 are pushed back to their original position when the product to be assembled is removed from the main frame 100, facilitating the next clamping operation and improving assembly efficiency.
[0067] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0068] The above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in this application.
