Detailed Implementation

[0031] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0032] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0033] like Figures 1-5 As shown, an embodiment of the present invention provides a handheld quick clamping device, including a mounting bracket 100, a clamping mechanism 200 and a pressing mechanism 300 mounted on the mounting bracket 100.

[0034] Specific reference Figure 1 and Figure 2 The mounting bracket 100 specifically includes an upper mounting bracket 110, a lower mounting bracket 120, and a side mounting bracket 130 connected between the upper mounting bracket 110 and the lower mounting bracket 120.

[0035] The clamping mechanism 200 is used to clamp and fix the first fastening member 400.

[0036] Specific reference Figure 1 and Figure 3 The clamping mechanism 200 includes at least one jaw unit, which includes a connecting shaft 210, a connecting rod mounting block 220, two connecting rods 230, and two jaws 240. The upper end of the connecting shaft 210 passes through the upper mounting base 110 and is connected to a handle 250. The lower end of the connecting shaft 210 is connected to the connecting rod mounting block 220. A spring 260 is fitted on the connecting shaft 210 and supports it between the upper mounting base 110 and the connecting rod mounting block 220. The two connecting rods 230 are respectively hinged to the lower end of the connecting rod mounting block 220. The middle parts of the two jaws 240 are respectively hinged to the two sides of the lower mounting base 120. The upper ends of the two jaws 240 are respectively hinged to the lower ends of the two connecting rods 230. The lower end of the jaws 240 has a hook 241 that can engage with the side of the first fastening member 400.

[0037] In practice, such as Figure 5 As shown, we can provide slots on the first fastening member 400. When the clamping mechanism 200 clamps and fixes the first fastening member 400, the spring 260 presses down on the connecting rod mounting block 220, causing the connecting rods 230 on both sides of the connecting rod mounting block 220 to push the upper ends of the two claws 240 outwards, thereby causing the hooks 241 at the lower ends of the two claws 240 to be locked into the slots on both sides of the first fastening member 400. When it is necessary to release the clamping mechanism 200, pull the handle 250 upwards. The handle 250 drives the connecting shaft 210 to move upwards, and the connecting rod mounting block 220 moves upwards along with the connecting shaft 210. The spring 260 is compressed. At this time, the connecting rod mounting block 220 pulls the upper ends of the two claws 240 inwards through the connecting rods 230 on both sides, thereby causing the hooks 241 at the lower ends of the two claws 240 to rotate outwards and exit the slots on both sides of the first fastening member 400.

[0038] In one embodiment, to ensure balance when clamping and fixing the first fastening member 400, the clamping mechanism 200 includes two sets of claw units, which are symmetrically arranged on both sides of the pressing mechanism 300. The handle 250 adopts a U-shaped structure, with both ends of the handle 250 bent downwards and connected to the upper ends of the connecting shafts 210 of the two sets of claw units, so that the two claw units can be lifted simultaneously through the handle 250.

[0039] The clamping mechanism 300 is used to clamp the second fastening member 500 onto the first fastening member 400.

[0040] Specific reference Figure 1 and Figure 4The clamping mechanism 300 includes a telescopic cylinder 310, an upper connecting block 320, and a lower clamping block 330. The telescopic cylinder 310 is fixed to the lower side of the upper mounting base 110. The telescopic cylinder 310 can be a pneumatic telescopic cylinder 310 or an electric telescopic cylinder 310, preferably a pneumatic telescopic cylinder 310. The upper connecting block 320 is located on the upper side of the lower mounting base 120 and fixed to the output shaft of the telescopic cylinder 310. The lower clamping block 330 is located on the lower side of the lower mounting base 120, and a plurality of guide posts 340 passing through the lower mounting base 120 are provided between the lower clamping block 330 and the upper connecting block 320.

[0041] like Figure 5 As shown, after the clamping mechanism 200 clamps the first fastening member 400, the telescopic cylinder 310 pushes the pressing block 330 to press the second fastening member 500 in the direction of the first fastening member 400, so that the first fastening member 400 and the second fastening member 500 are fastened together. The operation is simple, quick and labor-saving, and the pressing effect is stable.

[0042] To facilitate the installation of the telescopic cylinder 310, a telescopic cylinder mounting seat 111 is provided on the lower side of the upper mounting base 110, and the upper end of the telescopic cylinder 310 is fixed to the telescopic cylinder mounting seat 111 by bolts.

[0043] Continue to refer to Figure 1 The upper connecting block 320 is connected to several adjusting screws 321. The adjusting screws 321 are used to abut against the lower mounting base 120 to control the downward stroke of the upper connecting block 320. In actual operation, we can adjust the downward stroke of the upper connecting block 320 by adjusting the height of the lower end of the adjusting screw 321, thereby controlling the downward position of the lower pressing block 330, so as to adapt to the needs of different first fastening parts 400 and second fastening parts 500.

[0044] Preferably, the lower mounting base 120 is connected to two sides of a guide member 121 that extends downward and is respectively attached to both sides of the lower clamping block 330. The guide member 121 can guide the lower clamping block 330.

[0045] Preferably, the lower clamping block 330 has a downwardly extending workpiece shape positioning member 331 on its periphery. The lower clamping block 330 can be pre-positioned with the workpiece by the workpiece shape positioning member 331, and then the clamping mechanism 200 performs a clamping action. This makes it easy to align the jaws 240 of the clamping mechanism 200 with the clamping position.

[0046] To reduce the weight of the entire device, weight-reducing holes are provided on the upper mounting base 110, the lower mounting base 120, and the lower clamping block 330.

[0047] When the first fastening member 400 and the second fastening member 500 are fastened together, the clamping mechanism 200 of the clamping device can clamp and fix the first fastening member 400, and the pressing mechanism 300 can press and fasten the second fastening member 500 onto the first fastening member 400. When fastening, the device will apply a clamping force that squeezes the first fastening member 400 and the second fastening member 500 towards the middle, rather than pressing the second fastening member 500 against the first fastening member 400. When fastening, no pressure will be generated on the base on which the first fastening member 400 is installed, and the base will not be squeezed and damaged.

[0048] In this embodiment, the workpiece fastened by the clamping device is a junction box in a solar photovoltaic module. The first fastening member 400 is the junction box body, and the second fastening member 500 is the junction box top cover. The junction box body is fixed to one side of the photovoltaic panel. By using this device to fasten the junction box top cover onto the body, no pressure is applied to the photovoltaic panel, thus preventing damage to the photovoltaic panel when fastening the junction box top cover.

[0049] Of course, in other embodiments, the workpiece fastened by the clamping device can also be other workpieces that require two parts to be fastened together.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
