Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] See also Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a clamp after clamping a plate 1 according to an embodiment is shown. Figure 2 FIG. 2 shows a schematic diagram of the structure of a clamp according to an embodiment of the present invention. Figure 1 and Figure 2 In one aspect, an embodiment of the present application discloses a clamp, including a support table 100, a first clamping assembly, a second clamping assembly and an adjustment mechanism.

[0038] Among them, the support platform 100 is used to support the first clamping component, the second clamping component and the adjustment mechanism. The second clamping component and the second clamping component are used to fix the plate 1 that needs to be spliced ​​at a preset angle. The adjustment mechanism is used to adjust the interval between the second clamping component and the first clamping component to facilitate clamping the plate 1 to the fixture or removing the plate 1 from the fixture.

[0039] The support platform 100 is provided with angle scale lines, and the first plate 210 and the second plate 220 are arranged on the support platform 100. The angle scale lines are arranged with the rotation axis of the first plate 210 and the second plate 220 as the center, and the angle between the first plate 210 and the second plate 220 can be reflected by the angle scale lines.

[0040] See also Figure 1 and Figure 2 The first clamping assembly includes a first plate 210, a second plate 220 and a first rotating shaft 230. The first plate 210 and the second plate 220 are rotatably connected through the first rotating shaft 230, and the first rotating shaft 230 is provided with a first connecting portion fixedly connected to the support platform 100. The support platform 100 is provided with a first connecting hole 130, and the first connecting portion is threadedly connected to the first connecting hole 130. Specifically, one end of the first rotating shaft 230 is provided with the first connecting portion, and the other end is provided with a limiting structure. The diameter of the circumscribed circle of the limiting structure is greater than the diameter of the first rotating shaft 230, so as to prevent the first rotating shaft 230 from being separated from the first plate 210 and the second plate 220 from the side where the limiting structure is provided.

[0041] In practical applications, rotating the first rotating shaft 230 can make the limiting structure move along the axial direction of the first rotating shaft 230 toward the direction close to the first connecting hole 130. In this way, the first plate 210 and the second plate 220 can be abutted against the support platform 100 with the help of the limiting structure, which can effectively prevent the first plate 1 and the second plate 1 from rotating. Reversely rotating the first rotating shaft 230 makes the distance between the limiting structure and the support platform 100 greater than the height of the first plate 1 and the second plate 1. In this way, the first plate 1 and the second plate 1 can be loosened, and at this time, the angle of the first plate 210 and the second plate 220 can be adjusted.

[0042] Please continue to see Figure 1 and Figure 2The second clamping assembly includes a third plate 310, a fourth plate 320, a second rotating shaft 330 and a connecting block 340. The third plate 310 and the fourth plate 320 are rotatably connected via the second rotating shaft 330. The third plate 310 is disposed on one side of the first plate 210, and the fourth plate 320 is disposed on one side of the second plate 220. The second rotating shaft 330 is provided with a second connecting portion 321. The connecting block 340 is movably disposed on the support platform 100, and the connecting block 340 is provided with a second connecting hole 341 threadedly connected to the second connecting portion 321.

[0043] Specifically, a second connecting portion 321 is provided at one end of the second rotating shaft 330, and a limiting structure is provided at the other end. The diameter of the circumscribed circle of the limiting structure is larger than the diameter of the second rotating shaft 330 to prevent the second rotating shaft 330 from detaching from the third plate 310 and the fourth plate 320 from the side where the limiting structure is provided.

[0044] In practical applications, rotating the second rotating shaft 330 can make the limiting structure move along the axial direction of the first rotating shaft 230 toward the direction close to the first connecting hole 130. In this way, the third plate 310 and the fourth plate 320 can be abutted against the support platform 100 with the help of the limiting structure, which can effectively prevent the third plate 1 and the fourth plate 1 from rotating. Reversely rotating the second rotating shaft 330 makes the distance between the limiting structure and the support platform 100 greater than the height of the third plate 1 and the fourth plate 1. In this way, the third plate 1 and the fourth plate 1 can be loosened, and at this time, the angle of the third plate 310 and the fourth plate 320 can be adjusted.

[0045] It is worth understanding that the angle between the first plate 210 and the second plate 220 can be set as needed. For example, the angle between the first plate 210 and the second plate 220 can range from 0 to 180 degrees. In practical applications, the angle between the two can be adjusted to 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, etc., which is not limited here.

[0046] Please continue to see Figure 1 and Figure 2 The adjusting mechanism is connected to the connecting block 340, and the adjusting mechanism drives the connecting block 340 to move to change the positions of the third plate 310 and the fourth plate 320. In this way, the third plate 310 and the fourth plate 320 can press the plate 1 to be spliced ​​onto the first plate 210 and the second plate 220.

[0047] The working principle of the clamp in the embodiment of the present application is as follows:

[0048] When clamping the plate 1 to be spliced, the adjustment mechanism is used to drive the second clamping assembly to move in the direction away from the first clamping assembly, and the angle between the first plate 210 and the second plate 220 is adjusted according to the preset splicing angle of the plate to be spliced. Then, the plate 1 to be spliced ​​is placed between the first clamping assembly and the second clamping assembly, and the plate 1 to be spliced ​​is made to fit with the first plate 210 and the second plate 220. Then, the adjustment mechanism is used to drive the second clamping assembly to move toward the side close to the first clamping assembly. In this process, the first clamping assembly and the second clamping assembly can gradually clamp and tighten the plate 1 to be spliced.

[0049] In the embodiment of the present application, the components of the clamp are simple in structure and easy to connect, so that the user can assemble the clamp at the construction site, which can effectively improve the portability of the clamp. When in use, the angles of the first plate 210 and the second plate 220 can be adjusted to achieve assembly of the plate 1 according to a preset angle, which can improve the splicing efficiency of the plate 1 and also help improve the splicing quality of the plate 1.

[0050] In some embodiments of the present application, see Figure 3 , Figure 3 FIG. 2 shows an exploded structural diagram of a clamp according to an embodiment of the present invention. Figure 3 As shown, the support platform 100 includes a base plate 110 and a protractor plate 120, wherein the protractor plate 120 is mounted on the base plate 110, and the angle scale is set on the protractor plate 120. Specifically, the first connecting hole 130 is set on the base plate 110, and the protractor plate 120 is provided with a through hole for the first rotating shaft 230 to rotate, so that the first rotating shaft 230 can pass through the through hole and connect with the first connecting hole 130 located on the base plate 110. Among them, the first clamping assembly and the second clamping assembly are arranged on the protractor plate 120.

[0051] In a possible implementation manner, the protractor plate 120 is provided with a plurality of fastening holes, and the plurality of fastening holes are used to penetrate fasteners so that the protractor plate 120 is fixedly connected to the base plate 110 .

[0052] In some other embodiments, the support platform 100 is only provided with a bottom plate 110 , and the angle scale lines and the first connection holes 130 are directly provided on the bottom plate 110 .

[0053] In some embodiments of the present application, the first clamping assembly further includes a locating pin (not shown in the figure), the angle plate 120 is provided with an angle groove 121, at least one of the first plate 210 and the second plate 220 is installed with a locating pin, and the locating pin is at least partially disposed in the angle groove 121. Specifically, the locating pin is disposed on the first plate 210 and / or the second plate 220, and the locating pin is at least partially disposed in the angle groove 121 and is movably connected to the angle groove 121. Among them, the edge of the angle groove 121 is provided with an angle scale line. The provision of the locating pin can effectively position the plate and is also convenient for accurate positioning of the angle.

[0054] In a possible implementation, positioning pins are connected to both the first plate 210 and the second plate 220 , and the positioning pins are partially inserted into the angle grooves 121 , so as to adjust the plates to a position of a preset splicing angle.

[0055] In some embodiments of the present application, the bottom plate 110 is provided with an active groove 111 at a position corresponding to the angle groove 121, and the extension track of the active groove 111 is consistent with the angle groove 121. The positioning pin is at least partially embedded in the active groove 111, and the positioning pin is slidably connected to the active groove 111.

[0056] In some embodiments of the present application, see Figures 3 to 5 The first rotating shaft 230 is a first screw rod. The first plate 210 and the second plate 220 are both provided with a first hinge portion for connecting to each other. The first hinge portion is provided with a first through hole 221. The first screw rod is inserted into the first through hole 221, and the first screw rod is threadedly connected to the first connecting hole 130.

[0057] Specifically, the outer periphery of the first screw has a thread that can be threadedly connected to the first connecting hole 130. The end of the first screw away from the first connecting hole 130 has a limiting structure, and the limiting structure cannot pass through the first through hole 221. In this way, by rotating the first screw, the distance between the limiting structure and the support platform 100 can be gradually reduced, thereby clamping the first plate 210 and the second plate 220 between the limiting structure and the support platform 100 to prevent the first plate 210 and the second plate 220 from loosening after the angle is adjusted.

[0058] It is worth understanding that the first plate 210 has a first hinge structure, the second plate 220 has a second hinge structure, the first hinge structure and the second hinge structure are staggered, both the first hinge structure and the second hinge structure are provided with a first through hole 221, and the first hinge structure and the second hinge structure together constitute a first hinge part.

[0059] In some embodiments of the present application, the second rotating shaft 330 is a second screw, and the second plate 220 and the third plate 310 are both provided with a second hinge portion for connecting to each other, the second hinge portion is provided with a second through hole 311, the second screw is passed through the second through hole 311, and the second screw is threadedly connected to the second connecting hole 341.

[0060] Specifically, the outer periphery of the second screw has a thread that can be threadedly connected to the second connecting hole 341. The end of the second screw away from the second connecting hole 341 has a limiting structure, and the limiting structure cannot pass through the second through hole 311. In this way, by rotating the second screw, the distance between the limiting structure and the support platform 100 can be gradually reduced, thereby clamping the first plate 210 and the second plate 220 between the limiting structure and the support platform 100 to prevent the first plate 210 and the second plate 220 from loosening after the angle is adjusted.

[0061] It is worth understanding that the third plate 310 has a third hinge structure, the fourth plate 320 has a fourth hinge structure, the third hinge structure and the fourth hinge structure are staggered, the third hinge structure and the fourth hinge structure are both provided with a second through hole 311, and the third hinge structure and the fourth hinge structure together constitute a second hinge part.

[0062] In this embodiment, a driving structure for driving the first screw and the second screw is provided at the top of the first screw and the second screw. The staff can dock the driving tool in the driving structure to drive the rotation. In practical applications, the driving structure can be a slot, a cross slot or an inner polygonal hole. Correspondingly, the driving tool can be a slotted screwdriver, a cross screwdriver, etc.

[0063] In some embodiments of the present application, see Figures 1 to 5 The adjustment mechanism includes a fixed block 410, a pull rod 420, an elastic member, and a support block 430.

The elastic member is used to drive the pull rod 420 to move toward the direction close to the first clamping assembly.

[0064] It is worth understanding that, in the absence of external force, the elastic member can drive the second clamping assembly connected to the connecting block 340 to fit with the first clamping assembly to ensure that the second clamping assembly and the first clamping assembly can clamp the plate 1 to be spliced.

[0065] In some embodiments of the present application, the elastic member is a spring (not shown in the figure), which is sleeved on the outer periphery of the pull rod 420, and one end of the spring abuts against the fixed block 410, and the other end of the spring abuts against the support block 430.

[0066] It is worth understanding that when the spring is in a free state, the third plate 310 abuts against the first plate 210 , and the fourth plate 320 abuts against the second plate 220 .

[0067] In this embodiment, the fixing block 410 is specifically a nut, which is fixedly connected to the connecting block 340 , and one end of the pull rod 420 is threadedly connected to the nut.

[0068] In some embodiments of the present application, the support block 430 is provided with a through hole for the pull rod 420 to pass through, and a pull ring 440 is provided at one end of the pull rod 420 away from the fixed block 410, and the size of the pull ring 440 is larger than the size of the through hole.
