Description

Technical Field

[0001] This utility model relates to the technical field of clamping devices, and in particular to a clamping device that can quickly adjust the locking mechanism. Background Technology

[0002] While existing clamping devices for holding camera equipment (such as mobile phones and cameras) can meet certain usage requirements, they still have some structural shortcomings. For example, Chinese patent CN 221121645U discloses a novel clamping device in which the locking of the adjusting rod is achieved by turning the screw to drive the drive screw to rotate, and the drive screw to drive the locking block to abut against the adjusting rod. This method requires the use of a wrench to drive the screw to rotate in order to lock or unlock the adjusting rod, which is relatively cumbersome. Therefore, how to design a clamping device that can quickly lock or unlock the adjusting rod has become an urgent technical problem to be solved. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a clamping device that can quickly adjust the locking to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a clamping device capable of rapid adjustment and locking is designed, comprising: a clamping frame, an adjusting rod, a clamping block, a locking block, and a cam locking handle. The adjusting rod is movably engaged with the through hole at the upper end of the clamping frame. The clamping block is connected to the lower end of the adjusting rod. When the clamping block moves down and engages with the lower part of the clamping frame, a clamping action can be performed. The locking block is laterally engaged in the mounting groove provided at the top of the clamping frame. The cam locking handle is located on the left side of the clamping frame, and a connecting rod on it passes through the through hole on the clamping frame and is connected to the locking block. When the handle of the cam locking handle is turned, the connecting rod can drive the locking block to move left and right to abut or separate from the adjusting rod, so as to lock or release the adjusting rod.

[0006] Using the above technical solution, when it is necessary to adjust the height of the clamping block to clamp another camera device, pulling the handle of the cam locking handle upward will drive the connecting rod to move the locking block away from the adjusting rod, thus releasing the locking of the adjusting rod. Then the adjusting rod can be moved up and down to adjust the height of the clamping block to clamp another camera device. When it is necessary to lock the adjusting rod, pulling the handle of the cam locking handle downward will drive the connecting rod to move the locking block to abut against the adjusting rod, thus locking the adjusting rod. Compared with the need to use a wrench to drive the screw to rotate in order to lock or unlock the adjusting rod, the cam locking handle structure can quickly lock or unlock the adjusting rod. The adjustment is simple, convenient and quick, and the effect is good.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, a compression spring is provided on the left side of the locking block. The left end of the compression spring abuts against the wall of the mounting groove, and the right end abuts against the locking block. When the adjusting rod is in the unlocked state, the compression spring can drive the locking block to not contact the adjusting rod, facilitating the adjustment of the adjusting rod. In addition, when the adjusting rod is in the locked state and the handle is turned to unlock, the elastic force applied by the compression spring to the locking block facilitates the rotation of the handle to unlock.

[0009] In some embodiments, the locking block is provided with a locking groove, which, when the locking block is driven to move, causes the sidewall of the locking groove to abut against the adjusting rod to lock and fix it. The locking groove can achieve a good locking and fixing effect on the adjusting rod.

[0010] In some embodiments, the locking block has a through groove in the middle, the mounting groove has an extension block extending into the through groove, the through hole passes through the right side of the extension block, and the locking groove is located on the right side of the through groove.

[0011] In some embodiments, the top of the clamping frame is connected to a cover plate that covers the mounting slot, and the cover plate has a through hole for the adjustment rod to pass through.

[0012] In some embodiments, a screwing part is fixedly connected to the upper end of the adjusting rod, and the clamping block is rotatably connected to the adjusting rod.

[0013] In some embodiments, the locking groove has an internal thread on its wall that mates with the external thread on the adjusting rod. This provides a better locking and fixing effect on the adjusting rod.

[0014] In some embodiments, the connecting rod is threaded into a threaded hole on the locking block.

[0015] In some embodiments, the lower end of the clamping block is provided with an upper clamping groove with an inverted V-shaped structure, and the top of the lower end of the clamping frame is provided with a lower clamping groove with a V-shaped structure that corresponds vertically to the upper clamping groove.

[0016] In some embodiments, the locking block has two blind holes on its left end, and the right ends of the two compression springs are respectively placed in the two blind holes. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, and fixing should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] refer to Figures 1 to 4 As shown, the present invention provides a clamping device capable of quick adjustment and locking, comprising: a clamping frame 1, an adjusting rod 2, a clamping block 3, a locking block 4, and a cam locking handle 5.

[0027] The adjusting rod 2 is movably engaged with the through hole 10 at the upper end of the clamping frame 1. The adjusting rod 2 can move up and down along the through hole 10 to adjust the height. The upper end of the adjusting rod 2 is fixedly connected to a screwing part 21. Rotating the screwing part 21 drives the adjusting rod 2 to rotate. The clamping block 3 is fixedly connected to the lower end of the adjusting rod 2 by screws, or the clamping block 3 is rotatably connected to the lower end of the adjusting rod 2 by a hinge screw 6. In this embodiment, it is preferred that the clamping block 3 is rotatably connected to the lower end of the adjusting rod 2 by a hinge screw 6. Specifically, the upper end of the hinge screw 6 passes through the through hole on the clamping block 3 and is threadedly engaged with the threaded hole on the adjusting rod 2. The screw head at the lower end of the hinge screw 6 is located in the countersunk groove at the bottom of the clamping block 3. The clamping block 3 can rotate relative to the adjusting rod 2.

[0028] The clamping block 3 has an inverted V-shaped upper clamping groove 31 at its lower end, and a V-shaped lower clamping groove 11 at the top of the lower end of the clamping frame 1. The lower clamping groove 11 corresponds to the upper clamping groove 31. When the clamping block 3 moves down, the camera device can be clamped by the cooperation of the upper clamping groove 31 and the lower clamping groove 11.

[0029] The clamping frame 1 has a mounting groove 12 at the top and a connecting hole 13 at the left end to connect the outside with the mounting groove 12. The locking block 4 is laterally movable and fits in the mounting groove 12. A compression spring 7 is provided on the left side of the locking block 4. The left end of the compression spring 7 abuts against the groove wall of the mounting groove 12, and the right end of the compression spring 7 abuts against the locking block 4. Furthermore, the left end of the locking block 4 has two blind holes 41, and the right ends of the two compression springs 7 are placed in the two blind holes 41 respectively and abut against the locking block 4.

[0030] The locking block 4 has a through groove 42 in the middle. An extension block 14 extending into the through groove 42 is provided in the mounting groove 12. The through hole 10 passes through the right side of the extension block 14. The locking block 4 has a locking groove 40 on the right side of the through groove 42.

[0031] The cam locking handle 5 is located on the left side of the clamping frame 1. The connecting rod 52 on the cam locking handle 5 passes through the connecting hole 13 on the clamping frame 1 and is connected to the locking block 4. When the handle 51 of the cam locking handle 5 is turned, the connecting rod 52 can drive the locking block 4 to move left and right. The left and right movement of the locking block 4 can cause the side wall of the locking groove 40 to abut or separate from the adjusting rod 2, so as to lock or unlock the adjusting rod 2. Specifically, when the adjusting rod 2 is in the locked state, the handle 51 is turned 90° clockwise. After the connecting rod 52 drives the locking block 4 to move to the right, the locking groove 40 separates from the adjusting rod 2 and does not contact it, so the locking of the adjusting rod 2 can be released. After release, the adjusting rod 2 can be quickly adjusted up and down. When the adjusting rod 2 is in the unlocked state, the handle 51 is turned 90° counterclockwise. The connecting rod 52 drives the locking block 4 to move to the left so that the locking groove 40 abuts against the adjusting rod 2, thereby locking the adjusting rod 2.

[0032] The cam locking handle 5 is a conventional component, including a handle 51, a connecting rod 52, and a hinge shaft 53. The upper end of the handle 51 is provided with a cam part 511, and the cam part 511 is provided with a hinge hole. The hinge shaft 53 is hinged to the hinge hole on the cam part 511. The distance between the hinge shaft 53 and the top surface of the cam part 511 is less than the distance between the hinge shaft 53 and the right side surface of the cam part 511. There is an arc-shaped surface between the top surface and the right side surface of the cam part 511. The left end of the connecting rod 52 has a screw head 521 and the right end has an external thread. The right end of the connecting rod 52 passes through the through hole on the cam part 511, the through hole on the hinge shaft 53, and the connecting hole 13 on the clamping frame 1, and is threaded to the threaded hole on the locking block 4 or welded to the locking block 4. In this embodiment, the right end of the connecting rod 52 is preferably threadedly fastened to the threaded hole on the locking block 4.

[0033] The adjusting rod 2 is a smooth rod lock or a threaded rod with external threads. When the adjusting rod 2 is a smooth rod, the groove wall of the locking groove 40 is not provided with internal threads. When the adjusting rod 2 is a threaded rod with external threads, the groove wall of the locking groove 40 is provided with internal threads that can cooperate with the external threads on the adjusting rod 2. In this embodiment, the adjusting rod 2 is preferably a threaded rod with external threads, and the groove wall of the locking groove 40 is provided with internal threads. When the internal threads on the locking groove 40 cooperate with the external threads on the adjusting rod 2, and the adjusting rod is not locked and fixed by 2, the rotating screw part 21 is rotated to drive the adjusting rod 2 to rotate, thereby adjusting the adjusting rod 2 up and down, realizing fine adjustment of the height of the clamping block 3, so as to clamp the camera equipment more stably and firmly.

[0034] The top of the clamping frame 1 is connected to a cover plate 8 that covers the mounting slot 12. The cover plate 8 is fixed to the clamping frame 1 by multiple screws. The cover plate 8 has a through hole for the adjusting rod 2 to pass through.

[0035] The above descriptions are merely some embodiments of this utility model.
