DETAILED DESCRIPTION

[0025] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Embodiments of the present utility model: Figure 1-Figure 2 As shown, the utility model proposes a clamping device for anti-glare plate wind load specimens, comprising a first clamping plate 1, a second clamping plate 2, two screw rods 3, a clamping bolt 4 and a clamping head 5; the first clamping plate 1 and the second clamping plate 2 are both long strip-shaped plates; the first clamping plate 1 and the second clamping plate 2 are arranged opposite to each other; first mounting holes 101 are provided at both ends of the first clamping plate 1, and second mounting holes 201 are provided at both ends of the second clamping plate 2; the first mounting hole 101 on the first clamping plate 1 and the second mounting hole 201 on the second clamping plate 2 are arranged opposite to each other, and the first mounting hole 101 and the second mounting hole 201 are both through holes.

[0027] The screw rod 3 passes through the corresponding first mounting hole 101 and the second mounting hole 201; two locking nuts 6 cooperating with the screw rod 3 are arranged on the screw rod 3, and the two locking nuts 6 are respectively located on the side of the first clamping plate 1 and the second clamping plate 2 away from each other; in order to facilitate manual screwing of the nuts, the locking nuts 6 are butterfly nuts. By turning the two locking nuts 6 on the screw rod 3, the first clamping plate 1 and the second clamping plate 2 can be clamped on the anti-glare plate. The length of the screw rod 3 is relatively long, between 30-50cm. In this way, the first clamping plate 1 and the second clamping plate 2 can be located on both sides of the anti-glare plate to be clamped without removing the screw rod 3, that is, the first clamping plate 1, the second clamping plate 2 and the two screw rods 3 form a circle. When in use, the clamping device is set on the anti-glare plate to be clamped through this loop, so that the first clamping plate 1 and the second clamping plate 2 are located on both sides of the anti-glare plate to be clamped. The diameter of the screw 3 ranges from 8 to 12 mm, and here the screw 3 having a length of 34 cm and a diameter of 10 mm is taken as an example.

[0028] In order to improve the clamping effect and adapt to the anti-glare plates of different shapes, locking holes 7 are provided on the first clamping plate 1 and the second clamping plate 2; the clamping bolt 4 is threadedly connected to the locking hole 7, and there are multiple locking holes 7; the locking holes 7 on the first clamping plate 1 are distributed along the length direction of the first clamping plate 1, and the locking holes 7 on the second clamping plate 2 correspond to the locking holes 7 on the first clamping plate 1 one by one. Here, the first clamping plate 1 and the second clamping plate 2 are each provided with seven locking holes 7, and the clamping bolt 4 adopts a 4.8-grade M10 high-strength bolt. The clamping head 5 is installed on the clamping bolt 4, and the clamping head 5 is located between the first clamping plate 1 and the second clamping plate 2. The anti-glare plate can be further fixed by the clamping bolt 4 and the clamping head 5, thereby increasing the clamping contact surface of the anti-glare plate and improving the clamping effect of the anti-glare plate. The clamping head 5 and the clamping bolt 4 can be fixedly connected or detachably connected.

[0029] During specific use, the clamping device is firstly put on the anti-glare plate to be clamped, so that the first clamping plate 1 and the second clamping plate 2 are located on both sides of the anti-glare plate to be clamped, and the locking nut 6 is rotated to make the first clamping plate 1 and the second clamping plate 2 clamp and fix the anti-glare plate from both sides of the anti-glare plate to be clamped, and then the clamping bolt 4 is rotated to make the clamping head 5 press against the anti-glare plate to be clamped, thereby increasing the clamping effect of the anti-glare plate and completing the clamping and fixation of the anti-glare plate to be clamped.

[0030] The number of clamping bolts 4 can be adjusted according to the shape of the anti-glare plate to be clamped. If the anti-glare plate to be clamped is wavy, the clamping bolts 4 on the first clamping plate 1 and the second clamping plate 2 can be staggered. Figure 3 shown.

[0031] In order to avoid the anti-glare plate being damaged due to the small contact area when the clamping head 5 contacts the anti-glare plate, the following method is adopted. Figure 5 As shown, the clamping head 5 includes a clamping block 51, and the clamping block 51 is ball-jointed with the clamping bolt 4. Specifically, the clamping block 51 is a rectangular block, and a connecting column 52 is fixedly installed on one side of the clamping block 51, and a ball head 53 is fixedly installed on the end of the connecting column 52 away from the clamping block 51; a ball socket 8 that cooperates with the ball head 53 is fixedly installed on the end of the clamping bolt 4 close to the clamping block 51. When in use, the arrangement of the clamping block 51 can increase the contact area with the anti-glare plate to be clamped, and by ball-jointing the clamping block 51 with the clamping bolt 4, the angle of the clamping block 51 can be adjusted, so that the clamping block 51 can better fit the anti-glare plate to be clamped.

[0032] In order to further make the clamping block 51 fit closely with the anti-glare plate to be clamped, a rubber layer 54 is provided on the side of the clamping block 51 away from the clamping bolt 4 .

[0033] See also Figure 4As shown, in order to avoid the limitation of the distance adjustment between the clamping block 51 and the corresponding first clamping plate 1 and second clamping plate 2 due to the influence of the ball head 53 and the ball socket 8 structure during actual use, the following measures are adopted: the locking hole 7 includes a first hole 71 and a second hole 72, the first hole 71 is located on the side close to the clamping head 5, the diameter of the first hole 71 is larger than the diameter of the second hole 72, and the ball head 53 and the ball socket 8 structure can be received in the first hole 71.

[0034] In order to further improve the application range of the clamping device and avoid the influence of the redundant clamping bolts 4 and clamping blocks 51 on the experiment when clamping the anti-glare plates of different shapes and specifications, the diameter of the first hole 71 can be set larger and the hole depth can be set deeper so that the clamping block 51 can be received in the first hole 71. In specific use, the unused clamping block 51 can be received in the first hole 71 by rotating the corresponding clamping bolt 4.

[0035] See also Figure 1 As shown, a pull ring 9 is provided on one side of the first clamping plate 1 away from the second clamping plate 2; the pull ring 9 is located at the midpoint of the first clamping plate 1. The pull ring 9 is provided to facilitate the connection between the traction device and the clamping device, and to facilitate the experiment. Further, the pull ring 9 is threadedly connected to the first clamping plate 1.

[0036] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
