Description

Technical Field

[0001] The utility model belongs to the technical field of test bench frames, and particularly relates to a damping test bench frame with an adjustable angle. Background Technique

[0002] A bench frame is a test workbench, which is a table used by enterprises and institutions such as hospitals, schools, chemical plants, and scientific research institutes for experimental testing and instrument storage. There are mainly the following types: all-steel structure experimental benches, steel-wood structure experimental benches, aluminum-wood structure experimental benches, all-wood structure experimental benches, PP structure experimental benches, etc.

[0003] At present, the test bench frames on the market are generally fixedly arranged, and it is rather troublesome to adjust their table tops when needed, and it is difficult to meet various tests in different environments and situations. Content of the Utility Model

[0004] The purpose of the utility model is to provide a damping test bench frame with an adjustable angle, which solves the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a damping test bench frame with an adjustable angle, which includes a base. Universal wheels are arranged at the bottom of the base, a hydraulic cylinder is arranged at the top of the base, and an angle adjustment mechanism is arranged at the top of the hydraulic cylinder. The angle adjustment mechanism includes a bracket and a plug post. The bottom of the bracket is fixedly connected to the output end of the hydraulic cylinder. A rotating shaft is rotatably connected inside the bracket. A table board is fixedly connected to the top of the rotating shaft. Slots are formed on the side surface of the rotating shaft. Compression springs are arranged inside the slots. Card slots are formed on the inner side walls of the slots. The plug post penetrates through and is slidably connected to the bracket. One end of the compression spring away from the inner wall of the slot is fixedly connected to the plug post. A pull block is fixedly connected to the end of the plug post away from the compression spring. A groove is formed at the top of the plug post. A telescopic spring is arranged inside the groove. An arc-shaped block is slidably connected inside the groove through the telescopic spring. A speed reduction mechanism is arranged on the side surface of the bracket.

[0007] Furthermore, the end of the plug post away from the pull block is located inside the slot. Initially, one-third of the arc-shaped block is located inside the card slot, and the arc-shaped block being stuck in the card slot makes the rotating shaft unable to rotate.

[0008] Furthermore, the arc-shaped block is made of stainless steel material, and the arc surface of the arc-shaped block faces left. The arc-shaped block made of stainless steel material has high strength and is not easy to rust and damage. When the arc surface of the arc-shaped block is squeezed, it will move into the groove.

[0009] Further, the opening sizes of the card slot and the groove are the same, and the depth of the groove is greater than the length of the arc-shaped block, so that the arc-shaped block can be completely retracted into the groove.

[0010] Further, the speed reduction mechanism includes a support plate, a hinge rod, and a contact block. The support plate is fixedly connected to the side of the bracket. A speed reduction block is fixedly connected to the top of the support plate. The contact block is hinged to the bottom of the pull block through the hinge rod. An elastic cord is fixedly connected to the side of the contact block, and the end of the elastic cord away from the contact block is connected to the bottom of the pull block.

[0011] Further, the overall shape of the speed reduction block is semi-cylindrical, and the material of the speed reduction block is rubber. When the contact block is squeezed against the rubber speed reduction block, resistance will be generated.

[0012] Further, the length of the contact block is greater than the distance from the bottom of the pull block to the top of the speed reduction block, so that the contact block will contact the speed reduction block when following the pull block to move.

[0013] The utility model has the following beneficial effects:

[0014] 1. By providing an angle adjustment mechanism, the utility model can achieve that when it is necessary to rotate the rotating shaft to adjust the angle of the table board, the pull block can be pulled to the left to make the plug post move to the left. At this time, the rotating shaft can be rotated to adjust the angle of the table board. When the pull block is released, the plug post will automatically move to the right to restore. At this time, the arc-shaped block is inserted into the corresponding card slot, making the rotating shaft unable to rotate and fixing the angle of the main table board. The angle adjustment is convenient and is beneficial for testing in different environments.

[0015] 2. By providing a speed reduction mechanism, the utility model can achieve that through the cooperation of components such as the support plate, the hinge rod, the contact block, and the speed reduction block, the speed of the compression spring rebounding and driving the plug post to move to the right to restore can be slowed down, preventing the oscillation caused by the too fast speed of the compression spring rebounding and driving the plug post to move to the right, which affects the service life of the overall device.

[0016] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1-6, the utility model relates to a damping test bench frame with an adjustable angle, which comprises a base 1. Universal wheels 2 are arranged at the bottom of the base 1. A hydraulic cylinder 3 is arranged at the top of the base 1. An angle adjustment mechanism 4 is arranged at the top of the hydraulic cylinder 3. The angle adjustment mechanism 4 includes a bracket 41 and an insertion post 47. The bottom of the bracket 41 is fixedly connected to the output end of the hydraulic cylinder 3. A rotating shaft 42 is rotatably connected to the inner side of the bracket 41. A table board 43 is fixedly connected to the top of the rotating shaft 42. A slot 44 is formed on the side surface of the rotating shaft 42. A compression spring 45 is arranged inside the slot 44. A clamping groove 46 is formed on the inner side wall of the slot 44. The insertion post 47 penetrates through and is slidably connected to the bracket 41. One end of the compression spring 45 away from the inner wall of the slot 44 is fixedly connected to the insertion post 47. A pulling block 48 is fixedly connected to the end of the insertion post 47 away from the compression spring 45. A groove 49 is formed at the top of the insertion post 47. A telescopic spring 410 is arranged inside the groove 49. An arc-shaped block 411 is slidably connected to the inside of the groove 49 through the telescopic spring 410. A speed reduction mechanism 5 is arranged on the side surface of the bracket 41.

[0028] One end of the insertion post 47 away from the pulling block 48 is located inside the slot 44. One-third of the arc-shaped block 411 is located inside the clamping groove 46 in the initial state. The arc-shaped block 411 being stuck in the clamping groove 46 makes the rotating shaft 42 unable to rotate.

[0029] The arc-shaped block 411 is made of stainless steel material, and the arc surface of the arc-shaped block 411 faces left. The arc-shaped block 411 made of stainless steel material has high strength and is not easy to rust and damage. When the arc surface of the arc-shaped block 411 is squeezed, it will move into the groove 49.

[0030] The opening sizes of the clamping groove 46 and the groove 49 are the same. The depth of the groove 49 is greater than the length of the arc-shaped block 411. The arc-shaped block 411 can be completely retracted into the groove 49.

[0031] The speed reduction mechanism 5 includes a support plate 51, a hinge rod 53 and a contact block 54. The support plate 51 is fixedly connected to the side surface of the bracket 41. A speed reduction block 52 is fixedly connected to the top of the support plate 51. The contact block 54 is hinged to the bottom of the pulling block 48 through the hinge rod 53. An elastic rope 55 is fixedly connected to the side surface of the contact block 54. One end of the elastic rope 55 away from the contact block 54 is connected to the bottom of the pulling block 48.

[0032] The overall shape of the speed reduction block 52 is semi-cylindrical, and the speed reduction block 52 is made of rubber material. When the contact block 54 is squeezed with the rubber material speed reduction block 52, resistance will be generated.

[0033] The length of the contact block 54 is greater than the distance from the bottom of the pulling block 48 to the top of the speed reduction block 52. When the contact block 54 moves following the pulling block 48, it will contact the speed reduction block 52.

[0034] A specific application of this embodiment is as follows: The entire device is moved to a suitable position through the universal wheels 2, and the hydraulic cylinder 3 is activated to drive the support 41 to rise or fall, thereby adjusting the height of the table board 43. When the angle of the table board 43 needs to be adjusted, the pull block 48 is pulled to the left, causing the insertion post 47 to move to the left. The compression spring 45 is stretched. When the insertion post 47 moves to the left, it drives the arc-shaped block 411 to move to the left and leave the card slot 46. At this time, the arc surface of the arc-shaped block 411 will be squeezed and retracted into the groove 49 without affecting the leftward movement of the insertion post 47. When the arc-shaped block 411 leaves the card slot 46, the restriction on the rotating shaft 42 is lost, allowing the rotating shaft 42 to rotate. At this time, rotating the rotating shaft 42 can adjust the angle of the table board 43, and the rotation amplitude is small and will not affect the operation of the compression spring 45. When the angle of the table board 43 is adjusted, the pull block 48 is released. At this time, the compression spring 45 rebounds, driving the insertion post 47 and the pull block 48 to move to the right and return to their original positions. When the groove 49 fits with the corresponding card slot 46 at this time, the telescopic spring 410 rebounds, driving the arc-shaped block 411 to snap into the card slot 46 at this time, thereby restricting the rotating shaft 42 from rotating any further, facilitating the adjustment of the angle of the table board 43, which is beneficial for testing in different environments and situations. When the pull block 48 is pulled to the left to drive the insertion post 47 to move to the left, the contact block 54 will contact the deceleration block 52 when it moves to the left following the pull block 48. At this time, the contact block 54 will deflect and will not be squeezed by the deceleration block 52. Subsequently, the elastic rope 55 drives the contact block 54 to return to its original position. When the compression spring 45 rebounds and drives the insertion post 47 and the pull block 48 to move to the right and return to their original positions, the contact block 54 contacts the deceleration block 52 and cannot deflect. At this time, extrusion will occur, generating a certain amount of resistance to slow down the speed of the insertion post 47 and the pull block 48 when they move to the right and return to their original positions, preventing the insertion post 47 from moving too quickly to the right due to the rebound of the compression spring 45, which may cause oscillations and affect the service life of the entire device.
