Technical Field
[0001] This utility model belongs to the field of display screens, and specifically relates to a substrate bearing shock absorption device. Background Technology
[0002] As a core component, the display substrate is characterized by high precision, high value, fragility, and extreme sensitivity to vibration.

[0003] The existing technology involves fixing the substrate to a carrier, which is then mounted on a guide rail for transport. The carrier and the guide rail are connected using fasteners made of resin / metal. While this fixing method is simple, it is not very effective at damping vibrations. Utility Model Content

[0022] Figure 2 yes Figure 1 Schematic diagram of the cross-section structure;
[0023] Figure 3 yes Figure 2 Enlarged view of the part
[0024] Among them, the bearing device 1, through hole 1a, hole 1b, guide rail 2, compression spring 3, first bushing 4, second bushing 5, bolt 6, third bushing 7, spring washer 8, and flat washer 9. Detailed Implementation
[0025] like Figure 1-3 As shown, this embodiment includes a bearing device 1, a guide rail 2, a compression spring 3, a first bushing 4, a second bushing 5, and a bolt 6.
[0026] The support device 1 is plate-shaped, and the base plate is mounted on the support device 1. A hole 1b is provided at the bottom of the support device 1, and a through hole 1a is provided at the bottom of the hole 1b.
[0027] The through hole 1a is specifically an oblong hole. The oblong hole can serve to adjust and align the mounting hole position, and at the same time, it is convenient to insert the bolt 6 into the through hole 1a at an inclined angle.
[0028] The guide rail 2 is located below the bearing device 1 and is parallel and coplanar with the bearing device 1. The guide rail 2 has a threaded hole at the position corresponding to the through hole 1a.
[0029] The compression spring 3 is coaxial with the through hole 1a, and the compression spring 3 is located between the bearing device 1 and the guide rail 2.
[0030] The first bushing 4 includes a sleeve portion and a flange portion. The sleeve portion of the first bushing 4 is inserted into the upper end of the compression spring 3 from top to bottom. The two sides of the flange portion of the first bushing 4 abut against the bottom surface of the bearing device 1 and the upper end surface of the compression spring 3, respectively.
[0031] The second bushing 5 also includes a sleeve portion and a flange portion. The sleeve portion of the second bushing 5 is inserted into the lower end of the compression spring 3 from bottom to top, and the two sides of the flange portion of the second bushing 5 abut against the lower end face of the compression spring 3 and the top surface of the guide rail 2, respectively.
[0032] In this embodiment, the first bushing 4 and the second bushing 5 are made of stainless steel.
[0033] Bolt 6 passes through through hole 1a, first bushing 4, compression spring 3, and second bushing 5 from top to bottom, and then connects to the threaded hole to fix the bearing device 1 on the guide rail 2.
[0034] In this embodiment, the flange portion of the first bushing 4 and the second bushing 5 can increase the contact area between the compression spring 3 and the bearing device 1 and the guide rail 2. While reducing vibration, the bearing device 1 can be stably fixed on the guide rail 2.
[0035] In this embodiment, the bottom of the support device 1 is provided with several through holes 1a, and the guide rail 2 is provided with several threaded holes corresponding to the through holes 1a. Several bolts 6 pass through the through holes 1a and are threadedly connected to the threaded holes to fix the support device 1 on the guide rail 2. Furthermore, the through holes 1a are arranged in a linear array.
[0036] In this linear structure, the first bushing 4 and the second bushing 5 can support the load-bearing device 1 relatively stably and smoothly.
[0037] Preferably, in this embodiment, the guide rail 2 is cylindrical, and a step with a certain depth is provided on the arc surface of the guide rail 2, with a threaded hole provided on the step.
[0038] In addition to providing a smooth and stable support for the flange of the second bushing 5, the upper arc surface of the guide rail 2 can also limit the compression amount of the compression spring 3, thus preventing the compression spring 3 from oscillating too much and reducing the amplitude of vertical vibration of the substrate.
[0039] Preferably, this embodiment also includes a third bushing 7, which also includes a sleeve portion and a flange portion. The sleeve portion of the third bushing 7 is inserted into the through hole 1a from top to bottom, and the flange portion of the third bushing 7 abuts against the nut of the bolt 6 and the upper end face of the through hole 1a respectively. The bolt 6 passes through the third bushing 7.
[0040] The presence of the third bushing 7 allows the through hole 1a to be made larger, making it easier for the bolt 6 to pass through the through hole 1a.
[0041] Furthermore, this embodiment also includes a spring washer 8 and a flat washer 9, which are fitted onto the bolt 6, positioned one above the other between the nut of the bolt 6 and the flange of the third bushing 7. The spring washer 8 and the flat washer 9 can increase the preload of the bolt 6. The flange of the third bushing 7 can increase the contact area with the flat washer 9.
[0042] Preferably, in this embodiment, the guide rail 2 is provided with a stepped hole, wherein the small-diameter hole is a threaded hole. The bolt 6 is a stepped shaft corresponding to the stepped hole, and the thread is provided on the small-diameter shaft of the bolt 6. During installation, the thread on the small-diameter shaft of the bolt 6 is threadedly connected to the threaded hole, and the end face of the large-diameter shaft of the bolt 6 exactly abuts against the bottom surface of the large-diameter hole of the stepped hole. This structure limits the tightening stroke of the bolt 6, and several bolts 6 can maintain the same height, avoiding uneven force on the bearing device 1.
