Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to a buckle type clamp. Background Art

[0002] A clamp is a fixing part commonly used in pipelines, such as pipes, grooved pipes, valves, etc. Usually, the left and right clamps are threadedly connected by bolts and threaded holes. In order to ensure the tightness between the clamp and the fastener to be fastened and prevent the clamp from falling off, the bolts and threaded holes are tightly connected, which makes it difficult to disassemble the left and right clamps without tools such as screwdrivers. In particular, rust may form at the connection between the bolts and threaded holes after long-term use, further increasing the difficulty of disassembly.

[0003] Therefore, how to design a snap-on hoop that can be quickly disassembled without using tools is a technical problem that needs to be solved. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a snap-on hoop, which solves the problem that the existing clamp is fixed by threads and bolts and is difficult to disassemble without tools, resulting in a certain degree of difficulty in disassembly.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises a left hoop and a right hoop, one end of the left hoop is provided with a connecting column, and one end of the right hoop is provided with a connecting tube, and the left hoop and the right hoop are connected by a hinge at one end away from the connecting column and the connecting tube; the rear end of the connecting column is fixedly arranged on the outer surface of the left hoop end; the outer wall of the connecting column is also movably sleeved with a rotating tube and the rotating tube is flush with the outer surface of the connecting column, and a limit plate is fixedly provided on the rotating tube; an installation groove is provided on the outer side wall of the front end of the connecting column, and a return spring and a limit block are provided in the installation groove, one end of the return spring is fixedly connected to the inner side wall of the installation groove, and the other end is fixedly connected to the outer surface of the limit block; a sliding groove matching the thickness of the limit plate is provided on the outer peripheral wall of the connecting tube, and a limit groove matching the length of the limit plate is provided on the top of the sliding groove on the outer peripheral wall of the connecting tube.

[0006] Furthermore, the front end and the rear end of the connecting column are both provided with pulling pieces, and the top end of the pulling piece is provided with a pulling ring.

[0007] Furthermore, a semi-cylindrical limiting strip is provided on the outer peripheral wall of the connecting column along the circumference of the connecting column, and a guide groove matching the shape and size of the limiting strip is opened on the inner side wall of the connecting tube.

[0008] Furthermore, the length of the connecting column is greater than the length of the connecting pipe.

[0009] The utility model has the following beneficial effects:

[0010] 1- The utility model provides a connecting column and a connecting pipe that are matched and connected to each other at the ends of the left hoop and the right hoop. The connecting column is passed through the connecting pipe by pressing the limit block. After the limit block is extended from the rear end of the connecting pipe, the position between the connecting column and the connecting pipe is relatively fixed. Compared with fixing the left hoop and the right hoop with bolts, the utility model can realize the function of convenient disassembly and assembly of the left and right hoops without using tools such as screwdrivers, and is highly practical.

[0016] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0017] See also Figure 1-2 As shown, the scheme includes a left hoop 1 and a right hoop 2, wherein one end of the left hoop 1 is provided with a connecting column 11, and one end of the right hoop 2 is provided with a connecting tube 21, and the left hoop 1 and the right hoop 2 are connected by a hinge at one end away from the connecting column 11 and the connecting tube 21.

[0018] The rear end of the connecting column 11 is fixedly arranged on the outer surface of the end of the left hoop 1; a rotating tube 111 is movably sleeved on the outer wall of the connecting column 11, and the rotating tube 111 is flush with the outer surface of the connecting column 11, and a limiting plate 1111 is fixedly arranged on the rotating tube 111; a mounting groove 112 is opened on the outer wall of the front end of the connecting column 11, and a return spring 1121 and a limit block 1122 are arranged in the mounting groove 112, one end of the return spring 1121 is fixedly connected to the inner wall of the mounting groove 112, and the other end is fixedly connected to the outer surface of the limit block 1122;

[0019] The outer wall of the connecting tube 21 is provided with a slot 211 matching the thickness of the limiting plate 1111, and the top of the slot 211 on the outer wall of the connecting tube 21 is also provided with a limiting slot 212 matching the length of the limiting plate 1111. The inner diameter of the connecting tube 21 is equal to the outer diameter of the connecting column 11.

[0020] In order to facilitate dragging of the connecting column 11, in this embodiment, a pulling member 114 is provided at both the front and rear ends of the connecting column 11, and a pulling ring 11411 is provided at the top of the pulling member 114. The outer diameter of the pulling member 114 is preferably smaller than the inner diameter of the connecting tube 21.

[0021] A semi-cylindrical limiting strip 113 is provided on the outer peripheral wall of the connecting column 11 along the circumference of the connecting column 11 , and a guiding groove 213 matching the shape and size of the limiting strip 113 is opened on the inner side wall of the connecting tube 21 .

[0022] The length of the connecting column 11 is greater than that of the connecting tube 21 . After the connecting column 11 is connected to the connecting tube 21 , the limit block 1122 is outside.

[0023] The working principle is roughly as follows:

[0024] Before installation, the left hoop 1 and the right hoop 2 are arranged outside the part to be engaged, the limit block 1122 is pressed to move the limit block 1122 in the direction of the installation groove 112, the connecting column 11 is inserted into the connecting tube 21, and the connecting column 11 is pushed from the rear end of the connecting column 11 to move in the connecting tube 21. At the same time, the limit plate 1111 passes through the slide groove 211 until the limit block 1122 passes through the connecting tube 21 and is placed on the outside of the connecting tube 21. At this time, the limit block 1122 is reset under the action of the reset spring 1121, and the rotating tube 111 is rotated in the direction of the limit groove 212 to place the limit plate 1111 in the limit groove 212. At this time, the connecting column 11 and the connecting tube 21 are relatively fixed.

[0025] The above description is only a specific implementation method of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the utility model.
