Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a clamping mechanism for water valve processing. Background Art

[0002] Water valves are a common control structure in modern society, which regulate and control the on / off status of each node in the water network and the water flow passing through.

[0003] In the prior art, a knob structure is usually provided on the top of the water valve. The water valve needs to be clamped and fixed during the processing of these knobs. As the water valve models change, the water valve sizes vary, and the curvature of the water valve surface also varies. The common clamping mechanism cannot be adjusted according to the changes in the water valve size and shape, resulting in insufficient fit between the clamping part and the curved surface of the water valve, affecting the stability of the clamping.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model discloses a clamping mechanism for water valve processing, comprising a base 1, and a positioning clamp 2 is arranged above the base 1:

[0021] A through slot 11 is provided inside the base 1, a slider 12 is slidably connected inside the through slot 11, a threaded rod 13 is rotatably connected inside the through slot 11, a rotary handle 14 is provided on the side of the base 1, a positioning platform 15 is fixedly connected to the upper surface of the base 1, a clamping slot 16 is provided on both sides of the slider 12 and the positioning platform 15, and a positioning slot 17 is provided inside the slider 12 and the positioning platform 15;

[0022] The clamp arm of the positioning clamp 2 is connected with a clamp piece 21 by bolts, and the end of the clamp piece 21 away from the positioning clamp 2 is rotatably connected with a connecting ring 22, and the internal thread of the connecting ring 22 is connected with an adjusting bolt 23. The bottom of the positioning clamp 2 is fixedly connected with a connecting seat 24, and a positioning bolt 25 is inserted into the interior of the connecting seat 24.

[0023] Specifically, the threaded rod 13 is arranged along the through slot 11 , passes through the slider 12 and is threadedly connected to the slider 12 , and the rotary handle 14 is coaxially connected to the threaded rod 13 .

[0024] In this embodiment, the slider 12 is slidably arranged inside the through groove 11 and cannot rotate due to the restriction of the opening of the through groove 11. During the rotation process, the threaded rod 13 drives the slider 12 to slide along the through groove 11 through the action of the thread, thereby adjusting the distance between the slider 12 and the positioning platform 15.

[0025] Specifically, the positioning groove 17 is a threaded groove, which passes through the slider 12 and the positioning platform 15 and is provided with an opening on the inner wall of the slot 16; the connecting seat 24 is overlapped above the slider 12 and the positioning platform 15, and a protrusion corresponding to the slot 16 is provided at the bottom of the connecting seat 24, and the connecting seat 24 is clamped with the slider 12 and the positioning platform 15; the positioning bolt 25 is inserted into the protrusion of the connecting seat 24, and the positioning bolt 25 is threadedly connected to the positioning groove 17.

[0026] In this embodiment, when the connecting seat 24 is combined with the slider 12 or the positioning platform 15, the protrusion at the lower end of the connecting seat 24 and the slot 16 are mutually engaged, which plays a preliminary fixing role in the combined connection between the connecting seat 24 and the slider 12 or the positioning platform 15. The threaded connection between the positioning bolt 25 and the positioning slot 17 plays a fixing role in the connection between the connecting seat 24 and the slider 12 or the positioning platform 15, thereby improving the ability of the clamping mechanism to withstand various forces during the water valve processing process.

[0027] Specifically, the clamping pieces 21 are arranged in an arc shape, and the clamping pieces 21 are symmetrically arranged in groups of two on the two clamp arms of the two positioning clamps 2 .

[0028] In this embodiment, the arc-shaped clip 21 is combined on the two clamp arms of the positioning clamp 2 to form an arc-shaped clamping structure. By replacing the clip 21, the inner arc surface of the clamping structure and the approximately cylindrical parts near the flanges at both ends of the water valve are fit together, thereby expanding the contact area between the clamping structure and the water valve and improving the stability of the clamping.

[0029] When in use, select the corresponding clip 21 according to the size of the water valve and the shape of the arc surface at both ends of the water valve close to the flange. Select four corresponding clips 21, respectively combine them on the two clamp arms of the positioning clamp 2 and fix them by bolts, and clamp the connecting seats 24 under the two positioning clamps 2 on the slider 12 and the positioning platform 15 respectively and bolt them into the positioning bolts 25 to fix them, so as to complete the combined installation of the device. During the clamping process, rotate the handle 14 to drive the threaded rod 13 to rotate, drive the slider 12 to approach or move away from the positioning platform 15, adjust the distance between the two positioning clamps 2 to make it match the positioning points at both ends of the water valve, use the cylindrical parts at both ends of the water valve as the positioning points, clamp it in the two positioning clamps 2, rotate the adjusting bolts 23 to tighten the jaws, so that the clip 21 fits tightly on the surface of the water valve, and complete the clamping and fixing.

[0030] To sum up, the clamping mechanism for processing water valves drives the slider 12 to slide by setting a threaded rod 13, which adjusts the distance between the two ends of the clamping mechanism so that the clamping mechanism can adapt to water valves of different lengths. The clamping piece 21 is movably connected with the positioning clamp 2. The clamping surface can be more closely fitted to the shape of the water valve by replacing the clamping piece 21, thereby expanding the contact area between the clamping structure and the water valve, thereby improving the stability of the clamping, expanding the scope of application of the clamping structure, and improving the clamping effect.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
