DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-3 As shown, a tensile strength detection device for a display stand comprises a test bench 1, a support foot 2 is arranged at the bottom of the test bench 1, a positioning groove 3 is arranged at one side of the test bench 1, a mounting frame 4 is arranged at one side of the positioning groove 3, a bidirectional screw rod 5 is arranged on the mounting frame 4, a rotating wheel 6 is arranged at one end of the bidirectional screw rod 5, and a clamping plate 7 is symmetrically arranged at one side of the mounting frame 4, the clamping plate 7 is slidably connected to the mounting frame 4, the clamping plate 7 is threadedly connected to the bidirectional screw rod 5, a card slot is opened at one side of the clamping plate 7, an elastic lining layer 8 is arranged inside the card slot, a fixing frame 9 is arranged on the upper surface of the test bench 1 and located at one side of the mounting frame 4, a card plate 10 is slidably connected to the fixing frame 9, the lower end of the card plate 10 is opened, an extension plate 11 is arranged at one side of the card plate 10, a tension sensor 12 is arranged on the lower surface of the extension plate 11, a traction device 13 is arranged on the test bench 1, and the output end of the traction device 13 is fixedly connected to the tension sensor 12.

[0019] The monitor bracket has important components such as a fixing clamp 19, a column 16, a support arm 17, and a connector 18. The fixing clamp 19 is used to fix the bracket to the desktop, the column 16 is used to significantly increase the height of the monitor, the support arm 17 is used to make small adjustments to the height and position of the monitor, and the connector 18 is connected to the monitor. The fixing clamp 19 is placed in the positioning groove 3. Through the positioning groove 3, the placement position of the fixing clamp 19 can be quickly found. Since the inner side of the fixing clamp 19 has an arc-shaped surface, in order to improve the tightness of the fitting of the positioning groove 3 of the fixing clamp 19, an arc-shaped surface is provided on one side of the positioning groove 3. When the upper inner surface and the side surface of the fixing clamp 19 are in contact with the upper surface and the side surface of the test bench 1, the inner arc surface of the fixing clamp 19 coincides with the arc surface of the positioning groove 3, and through the subsequent clamping of the clamping plate 7, the fixing position of the bracket is the same each time.

[0020] The overlapping area between the lining layer 8 on the clamping plate 7 and the column 16 is close to the upper middle part of the column 16, which is beneficial to improving the stability of the bracket clamping. The thickness of the lining layer 8 at both ends is the same, and the thickness of the lining layer 8 at both ends is greater than the thickness in the middle of the lining layer 8. By increasing the thickness of the lining layer 8 at both ends, the clamping stability of the clamping plate 7 and the lining layer 8 on the column 16 can be increased, and the distance between the effective action point of the lining layer 8 and the column 16 is prevented from being short, which affects the stability of the column 16.

[0021] When the rotating wheel 6 rotates, it can drive the bidirectional screw rod 5 to rotate, thereby controlling the two clamping plates 7 and the inner lining layer 8 to approach or move away from each other. When the two clamping plates 7 are close to each other, the column 16 can be clamped. When the two clamping plates 7 are away from each other, it is convenient to take out the bracket. Since the height position of the test bench 1 is limited by the height of the supporting foot 2, and the supporting foot 2 is different from a normal office desk, the length of the supporting foot 2 is shorter, resulting in a shorter distance between the test bench 1 and the placement plane. The fixing clamp 19 needs to fix the bracket by bolting, and the bolt needs to be operated from the bottom of the test bench 1. Therefore, the installation of the fixing clamp 19 is limited. Through the cooperation of the bidirectional screw rod 5, the clamping plate 7 and the inner lining layer 8, not only the height of the test bench 1 can be reduced, but also the bracket can be quickly fixed conveniently, and the fixing efficiency is high. A fixing rod 14 is provided on one side of the rotating wheel 6. The fixing rod 14 is convenient for controlling the rotation of the rotating wheel 6. The outer surface of the fixing rod 14 is rotatably connected with a sleeve 15. Through the sleeve 15, the friction between the fixing rod 14 and the hand can be reduced.

[0022] Side panels are provided at both ends of the card board 10, and a slide groove is provided inside the fixing frame 9. The card board 10 slides on the fixing frame 9 through the slide groove. The card board 10 can only move vertically up and down on the fixing frame 9. When it is necessary to test the tensile strength of the bracket, the bracket is first fixed to the test bench 1, and then the connector 18 is moved to the fixing clamp 19, and the connector 18 is allowed to enter the inside of the card board 10 through the lower end opening of the card board 10. It is only necessary to enter the connector 18 into the inside of the card board 10, and then control the output end of the traction device 13 to move downward. The traction device 13 can be an electric telescopic rod or a hydraulic cylinder. The output end of the traction device 13 drives the tension sensor 12 and the extension plate 11 to move downward, and at the same time drives the card board 10 and the connector 18 to move downward. The tension sensor 12 transmits data to the computer and controls the traction device 13 to continue working until the tension sensor 12 reaches a predetermined value, and maintains it at this value for a certain period of time to observe whether the bracket is deformed or damaged.

[0023] Working principle: When in use, place the fixing clamp 19 into the positioning groove 3 of the test bench 1, and align the fixing clamp 19 with the upper surface and side of the positioning groove 3, then control the rotation of the bidirectional screw 5 to drive the two clamping plates 7 to approach each other, and continuously squeeze the inner lining layer 8 through the clamping plates 7 and the column 16. After the inner lining layer 8 is deformed, the column 16 on the bracket can be fixed, and then the connector 18 is moved to the inside of the card plate 10, and then the connector 18 is driven downward by the traction device 13. When the tension sensor 12 reaches a predetermined value, the traction device 13 stops working and maintains the value for a certain period of time to observe whether the bracket is deformed or damaged.

[0024] The device can improve the installation stability and convenience of the display bracket through the cooperation of the bidirectional screw rod 5, the positioning groove 3, the clamping plate 7 and the lining layer 8. At the same time, it can also fix the bracket for testing in the same position each time, preventing the installation position of the bracket from changing and the bracket from loosening, which may cause inaccurate test results, thereby ensuring the accuracy and efficiency of the test.

[0025] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
