Each support leg 2 is provided with an adjustment mechanism, which is connected to the telescopic leg 5. The adjustment mechanism is provided with a limit component to adjust the telescopic leg 5 to extend out of the telescopic hole 201 to a preset length. The adaptive vertical pull-out testing construction method of the working surface in this utility model patent is similar in structure to existing external wall testing equipment, such as the bonding strength tester of model LR-6000C. Figure 2 - Figure 4 As shown, the adjustment mechanism includes an adjustment screw 6 disposed in the telescopic hole 201, a longitudinally arranged threaded hole 501 on the telescopic leg 5, the adjustment screw 6 being threadedly connected to the threaded hole 501, and a drive mechanism being connected to the upper end of the adjustment screw 6, the drive mechanism being rotatably connected to the support leg 2.

[0029] like Figure 1 - Figure 6 As shown, the drive mechanism includes a drive rod 7, the lower end of which is fixedly connected to an adjusting screw 6. A sliding hole 202 is provided on the support leg 2, which extends through to the telescopic hole 201. A hand-tightening cap 8 is fixedly connected to the upper end of the drive rod 7 through the sliding hole 202. The hand-tightening cap 8 is exposed on the support leg 2 for easy height adjustment. A limiting groove 203 is provided on the support leg 2 at the middle position of the sliding hole 202, which is connected to the sliding hole 202. A limiting ring 9 is provided in the limiting groove 203. The limiting ring 9 is sleeved on the drive rod 7 and fixedly connected to the drive rod 7. The limiting ring 9 is connected to the limiting component.

[0030] By twisting the hand cap 8, the driving rod 7 is driven to rotate. When the driving rod 7 rotates, the driving rod 7 can be kept from being deviated in position when rotating in the sliding hole 202 by rotating in the limiting groove 203. Then, when the adjusting screw rod 6 is driven to rotate, the adjusting screw rod 6 is kept from moving up and down, so that the telescopic leg 5 is driven to move in and out in the telescopic hole 201, and after the telescopic adjustment of the telescopic leg 5 is completed, the limiting ring 9 is fixed by the limiting assembly, so that the position of the telescopic leg 5 is fixed.

[0031] As shown in Figure 1 Figure 11 The supporting leg 2 is provided with a control hole 205 and a limiting sliding groove 204 communicating with the control hole 205, and the limiting sliding groove 204 is arranged through the limiting groove 203. The limiting assembly comprises a limiting plate 10 slidingly connected in the limiting sliding groove 204, a plurality of clamping grooves 901 are annularly arranged on the outer wall of the limiting ring 9, a plurality of clamping blocks 11 adapted to the clamping grooves 901 are arranged on the side of the limiting plate 10 close to the limiting ring 9, a rotating hole 101 is arranged in the middle of the limiting plate 10, a T-shaped rotating block 12 is rotatably connected in the rotating hole 101, the vertical part of the T-shaped rotating block 12 penetrates through the rotating hole 101 and is connected with a control rod 13, and the other end of the control rod 13 penetrates through the control hole 205. A plurality of positioning grooves 206 are annularly arranged on the supporting leg 2 along the control hole 205, the positioning grooves 206 are connected with the control hole 205 and communicate with the limiting sliding groove 204, and a positioning block 14 adapted to the positioning groove 206 is arranged on the outer wall of the control rod 13.

[0032] After the telescopic adjustment of the telescopic leg 5 is completed, the control rod 13 is rotated and pressed towards the limiting ring 9, then the two positioning blocks 14 are driven to slide into the positioning grooves 206 and slide into the limiting sliding groove 204 from the positioning grooves 206, at this time, the control rod 13 drives the limiting plate 10 and the clamping blocks 11 to move towards the limiting ring 9 through the T-shaped rotating block 12, and the plurality of clamping blocks 11 are inserted into the corresponding clamping grooves 901 on the limiting ring 9, so as to prevent the rotation of the limiting ring 9, and the telescopic leg 5 is fixed in the telescopic hole 201 by cooperating the driving rod 7 and the adjusting screw rod 6. Then, the control rod 13 is rotated again, the two positioning blocks 14 are misaligned with the two positioning grooves 206, and abut against the limiting sliding groove 204, so as to prevent the limiting assembly from moving outward and keep the fixing effect of the telescopic leg 5.

[0033] As shown in Figure 1 Figure 11 The end of the control rod 13 away from the limiting plate 10 is fixedly connected with a control cap 15, and the outer wall of the control cap 15 is provided with a plurality of anti-skid grooves 102. When the control rod 13 is rotated, the control cap 15 is twisted by hand, so that the control rod 13 can be more conveniently rotated, and the anti-skid grooves 102 can prevent the control cap 15 from slipping when being twisted, so that the twisting and rotating are easier.​​

[0034] As shown in Figure 5 - Figure 11 When the detection is completed, the control rod 13 is rotated to drive the two positioning blocks 14 to move to the position of the positioning groove 206, and the contraction spring 16 always provides elastic force to the limiting plate 10, so that when the two positioning blocks 14 move to the position of the two positioning grooves 206, the positioning blocks 14 are slid out of the positioning grooves 206 through the elastic force, so that the limiting plate 10 and the clamping block 11 are separated from the limiting ring 9, and at this time, the telescopic leg 5 can be retracted into the telescopic hole 201 of the supporting leg 2 by rotating the hand screw cap 8.

[0035] As shown in Figure 2 - Figure 4 The inner walls of the two sides of the telescopic hole 201 are provided with anti-falling grooves 207, and the two sides of the end of the telescopic leg 5 close to the positioning disc 1 are fixedly connected with anti-falling blocks 17 which are slidingly connected in the anti-falling grooves 207. During the process of the telescopic leg 5 extending out of the telescopic hole 201, the connection between the anti-falling block 17 and the anti-falling groove 207 can prevent the telescopic leg 5 from extending too much out of the telescopic hole 201 and falling off from the telescopic hole 201, thereby improving the connection stability between the telescopic leg 5 and the telescopic hole 201.

[0037] Step one: after the pulling block 4 is bonded with the detection block, the positioning disc 1 is installed and connected with the pulling block 4 through the pulling rod 3.

[0038] Step two: the telescopic leg 5 is driven by the driving mechanism on the supporting leg 2 to extend out of the telescopic hole 201 in the supporting leg 2 and abut against the working surface, and cooperates with the other telescopic leg 5 to finally make the pulling rod 3 and the pulling block 4 keep vertical; when adjusting, first, ensure that the positioning block 14 of the control rod 13 in the limiting assembly is located outside the supporting leg 2, that is, the clamping block 11 on the limiting plate 10 is not clamped in the clamping groove 901 of the limiting ring 9, and the adjusting mechanism is not limited, then, rotate the hand screw cap 8 to drive the adjusting screw 6 to rotate through the driving rod 7, at this time, the limiting ring 9 rotates with the adjusting screw 6 in the limiting groove 203; the telescopic leg 5 slides in the telescopic hole 201, and is adjusted to the appropriate position.

[0039] More specifically, when the adhesion strength detection is carried out on the uneven work surface, the length of the telescopic leg 5 can be adjusted and fixed on the supporting leg 2 through the adjusting mechanism and the limiting assembly, and the positioning disc 1 can be adjusted on the uneven work surface by cooperating with another telescopic leg 5, and finally the pulling rod 3 and the pulling block 4 are kept vertical, so that the pulling force after the detection is more accurate.

[0040] Step three: limiting the telescopic leg 5 through the limiting assembly; specifically, by rotating the control rod 13, and sliding the two positioning blocks 14 through the positioning groove 206 to the limiting sliding groove 204, at the same time, by the T-shaped rotating block 12, the limiting plate 10 is close to the limiting ring 9, finally the clamping block 11 on the limiting plate 10 is inserted into the clamping groove 901 on the limiting ring 9, then the control rod 13 is rotated again, the two positioning blocks 14 are dislocated with the positioning groove 206, and abut against the inner wall of the limiting sliding groove 204, the position of the limiting ring 9 is fixed, the driving rod 7 and the adjusting screw 6 no longer rotate, and the position of the telescopic leg 5 is fixed.

[0041] Step four: the pulling block 4 is peeled off from the bonding position of the pulling block 4 through the pulling rod 3, and the corresponding pressure reading is displayed through the tension sensor.

[0042] The adhesion strength detection device can adjust and fix the length of the telescopic leg on the supporting leg through the adjusting mechanism and the limiting assembly, and can adjust the positioning disc on the uneven work surface by cooperating with another telescopic leg, and finally the pulling rod and the pulling block are kept vertical, so that the pulling force after the detection is more accurate; the continuous adjustment of the telescopic leg is realized through the adjusting screw, the operation precision of the device is improved, and the device is suitable for the work surface with any flatness.

[0043] Although the embodiments of the utility model patent have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model patent.
