Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a quick-pressing and fixing clamp. Background Technology

[0002] When carving or processing the surface of some boards, appropriate clamps are used to fix the boards. However, traditional clamps usually clamp the boards on both sides or multiple sides, requiring adjustment of the fixing parts one by one, which is inconvenient. Therefore, it is necessary to develop a quick-pressing fixing clamp. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-6 The diagram shown is a structural schematic of an embodiment of the quick-pressing fixing clamp of this utility model. Please refer to [link / reference]. Figures 1-6 A detailed introduction is given to a quick-down pressing fixture.

[0027] A quick-down pressing fixture includes a base plate 100, on which a plate to be processed 110 is placed. At the top of the base plate 100, a down-pressing frame 120 for pressing and clamping the plate to be processed 110 is rotatably provided. The overall top-down cross-section of the down-pressing frame 120 is in the shape of a Chinese character 'hui'. An opening is provided on the down-pressing frame 120 for exposing the processing area of the plate to be processed 110. At the contact between the bottom of the down-pressing frame 120 and the top of the plate to be processed 110, an anti-slip rubber pad is provided. The top-down cross-section of the anti-slip rubber pad is in the shape of a Chinese character 'hui', which improves the friction when the down-pressing frame 120 presses the plate to be processed 110.

[0028] On the top of the base plate 100, fixing blocks 150 are symmetrically arranged before and after on the left side of the down-pressing frame 120. A rotating rod 160 is rotatably provided between the two fixing blocks 150. The rod body of the rotating rod 160 is connected to the left side of the down-pressing frame 120. A convex strip 130 protrudes from the right side edge of the down-pressing frame 120. Two jacks 140 are symmetrically opened in the front and back on the right side of the convex strip 130. The inner of the jack 140 is in the shape of a rectangular body. A convex block 170 protrudes from the right side wall of the down-pressing frame 120. The convex block 170 is in the shape of a 'T'. The protruding convex block 170 facilitates the user to hold and open or close the down-pressing frame 120.

[0029] Hollow mounting shells 200 are respectively provided near the two jacks 140 on the top of the base plate 100. Horizontally arranged inserting rods 210 are movably provided inside the two mounting shells 200. The rod body of the inserting rod 210 slidably penetrates through the left side wall of the mounting shell 200, and the outer side wall of the inserting rod 210 is fitted and inserted / extracted into the hole of the jack 140. Horizontally arranged screw rods 220 are rotatably provided inside the two mounting shells 200. The rod body of the screw rod 220 is screwed to the left side of the inserting rod 210. It should be noted that the outer side wall of the inserting rod 210 is fitted and slidably penetrates through the side wall of the mounting shell 200, so that the inserting rod 210 cannot rotate through the thread and can only move along the length direction of the screw rod 220.

[0030] A limiting plate 230 protrudes from the right end of the inserting rod 210 and is located inside the cavity of the mounting shell 200. The cross-sectional area of the limiting plate 230 is larger than that of the inserting rod 210. The limiting plate 230 limits the inserting rod 210 to ensure that the right part of the inserting rod 210 is always located inside the cavity of the mounting shell 200.

[0031] A hollow drive housing 300 is disposed between two mounting housings 200. The inner cavity of the drive housing 300 is symmetrically equipped with linkage rods 310. The ends of the two linkage rods 310 that are far apart rotate through the side wall of the mounting housing 200 and are equipped with first helical gears 320. The ends of the two screws 220 that are far away from the insertion rod 210 are equipped with second helical gears 330 that mesh with the first helical gears 320. The ends of the two linkage rods 310 that are close together are equipped with third helical gears 340. A vertical drive rod 350 is rotatably disposed through the top of the drive housing 300. A fourth helical gear 360 is disposed on the rod body of the drive rod 350 that meshes with both third helical gears 340. The upper end of the drive rod 350 is located at the top of the drive housing 300 and is equipped with a knob 370 at the upper end of the drive rod 350, which facilitates the rotation of the drive rod 350.

[0032] In practical use, the board to be processed 110 is placed on the substrate 100. The user rotates the pressure frame (120) with one hand through the protrusion 170, so that the pressure frame 120 presses the board to be processed 110 down onto the substrate 100. With the other hand, the user drives the drive rod 350 and the fourth helical gear 360 to rotate through the knob 370, and then drives the linkage rod 310 and the first helical gear 320 to rotate through the third helical gear 340. Then the second helical gear 330 drives the screw 220 to rotate, so that the insertion rod 210 moves and fits into the hole of the insertion hole 140, and fixes the pressure frame 120. The part of the board to be processed 110 that needs to be processed is exposed at the opening, which is convenient for subsequent engraving and other processes on the board to be processed 110.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
