[0010] A glass bracket 7 that slides up and down is provided below the button clamp 4 , and the glass bracket 7 is connected to a displacement sensor 8 that measures the degree of up and down displacement of the glass bracket 7 .

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting the angle guide plate 2 and the tape angle adjustment plate 3, the conditions of the object under test at different angles can be simulated, and the most comprehensive test tape creep information can be obtained to the greatest extent.

[0013] 2. The tape to be tested is adhered to the nail buckle, and the nail buckle is disassembled and installed on the nail buckle fixture 4. In addition, the glass is also placed in the glass bracket 7 and limited by the glass clamping slot 5. There is no overly complicated fixing method, which is convenient for replacing the experimental object later. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings:

[0020] like Figure 1-4 As shown: a tape creep test fixture, which includes a base 1, an angle guide plate 2 and a tape angle adjustment plate 3;

[0021] The tape angle adjustment plate 3 is rotatably mounted on the base 1 so that the tape angle adjustment plate 3 can achieve a rotation of 0-90°;

[0022] The angle guide plates 2 are installed on both sides of the tape angle adjustment plate 3, and the angle guide plates 2 guide the change of the angle of the tape angle adjustment plate 3;

[0023] Wherein, a button clamp 4 is provided on the front of the tape angle adjustment plate 3, and the button clamp 4 is used to clamp the button, and the tape to be tested is adhered to the button;

[0024] A glass slot 5 that slides up and down is provided above the fastener fixture 4, and a weight barrel 6 for placing a weight 61 is provided above the glass slot 5;

[0025] A glass bracket 7 that slides up and down is provided below the button clamp 4 , and the glass bracket 7 is connected to a displacement sensor 8 that measures the degree of up and down displacement of the glass bracket 7 .

[0026] When using it, first stick the measuring tape on the buckle, then lock the buckle with the buckle clamp. Then stick the glass on the tape. At this time, the upper part of the glass is limited by the glass clamping groove and the lower part is supported by the glass bracket.

[0027] After completing the above steps, adjust the angle of the tape angle adjustment plate 3 and lock it, then start placing weights to increase the weight of the glass and perform the tape creep test.

[0028] It should be noted that the button clamp 4 is a common clamp currently available, that is, a base with threaded seats on both sides, and a screw is provided on the threaded seats on both sides, and the button is clamped by the screws moving toward each other. Since it is a common structure currently available, it will not be described in detail.

[0029] A slide rail 51 is provided on the front of the tape angle adjustment plate 3 , and a slide seat 52 cooperating with the slide rail is provided on the back of the glass slot 5 , so that the glass slot 5 can slide up and down guided by the slide rail 51 .

[0030] The glass holder 7 is provided with longitudinally arranged extension arms 71 on both sides, and the tape angle adjustment plate 3 is provided with a guide hole 31 corresponding to the position of the extension arm 71. The extension arm 71 is provided with a guide piece 72 that passes through the guide hole 31 and extends to the back of the tape angle adjustment plate 3. The back of the tape angle adjustment plate 3 is provided with a connecting rod 73 connecting the two guide pieces 72;

[0031] The displacement sensor 8 is fixed to the back of the tape angle adjustment plate 3 and is connected to the connecting rod 73. Here, the displacement of the glass can be detected by the glass bracket 7 and the displacement sensor 8, and the creep of the tape can be further sensed.

[0032] Specifically, the glass bracket 7 is connected to the displacement sensor 8 via the guide piece 72 and the connecting rod 73 , wherein the guide hole 31 can limit the displacement distance of the glass bracket 7 .
