Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipe connection, and in particular relates to an anti-slipping fixed gear ring. Background Art
[0002] Compression fittings are a type of connector that uses a socket fitting with a special sealing ring, isolating ring and gear ring to connect pipes, and uses special tools to compress the pipe mouth to achieve sealing and fixing.
[0003] At present, the anti-slip and fixing tooth ring commonly used in compression pipe fittings generally adopts a steel ring with a row of sharp teeth embedded inside to ensure its anti-slip performance. However, since there is only one row of sharp teeth on the steel ring, it cannot effectively ensure that the pipe inserted in the pipe fitting will not slip out under the action of internal pressure or external tension. The anti-slip performance of the steel ring is poor, and it is very easy to slip out when the pipeline pressure is too high; and there is only one row of sharp teeth when it is used for compression, it is very easy to be pressed off and affect the use.

[0006] An embodiment of the utility model provides an anti-slip fixed gear ring, comprising a gear ring body, a plurality of sharp teeth are arranged on the edges of both sides of the gear ring body, and a right-angle protrusion is arranged between two adjacent sharp teeth.
[0007] Furthermore, the gear ring body is a C-shaped structure.
[0008] Furthermore, the pointed teeth protrude toward the inner side of the gear ring body.
[0009] Furthermore, the pointed teeth are integrally formed with the gear ring body.
[0010] Furthermore, the pointed teeth are evenly distributed on the gear ring body, and a plurality of pointed teeth are staggeredly distributed on the two side edges of the gear ring body.
[0011] Furthermore, the sharp teeth on both side edges of the gear ring body are symmetrically arranged.
[0012] Furthermore, the right-angle protrusion is integrally formed with the gear ring body.
[0013] Furthermore, the width of the right-angle protrusion is smaller than the distance between two adjacent sharp teeth, and the distance between two adjacent right-angle protrusions is the same.
[0014] Furthermore, the height of the right-angle protrusion is greater than the height of the sharp tooth, and the right-angle protrusion protrudes from the outer side of the sharp tooth.
[0015] Furthermore, the right-angle protrusion is matched with the straight stop on the socket end face of the compression type pipe fitting.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] The utility model provides a double-row sharp tooth structure on the gear ring and provides right-angle protrusions on the gear ring, thereby greatly ensuring the anti-loosening performance and the parallelism of the pipeline, and improving the quality and service life of the clamping type gear ring.

[0019] Figure 2 This is a structural diagram of the socket of the compression type pipe fitting in the embodiment of the utility model;
[0020] Among them, 1. gear ring body; 2. sharp teeth; 3. right-angle protrusion; 4. socket of compression type pipe fitting; 5. straight stop; 6. connecting pipe fitting. DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] A typical implementation of the present utility model is as follows Figure 1 As shown, an anti-slip fixed gear ring includes a gear ring body 1. The gear ring body 1 is a C-shaped structure, so that the gear ring body 1 has the ability to shrink radially, thereby ensuring that there is a certain amount of shrinkage during crimping. The side wall of the gear ring body 1 is fixed with sharp teeth 2 protruding inward, and the sharp teeth 2 are integrally formed with the gear ring body 1, so that the gear ring body 1 can firmly fasten the connecting pipe 6 after shrinking, which plays a good tensile resistance role and enhances the connection stability between the gear ring and the connecting pipe 6.
[0023] There are multiple sharp teeth 2 equidistantly distributed on the gear ring body 1 . The multiple sharp teeth 2 are staggeredly distributed on the two side edges of the gear ring body 1 , and the two rows of sharp teeth 2 on both sides of the gear ring body 1 are symmetrically arranged.
[0024] By arranging two rows of symmetrically arranged sharp teeth 2 protruding toward the inner side of the gear ring body 1 on the gear ring body 1, the anti-loosening performance of the gear ring and the parallelism of the pipeline are greatly guaranteed, avoiding the situation where the single row of sharp teeth is easily removed after being pressed and is easily flattened during pressing.
[0025] A plurality of right-angle protrusions 3 are also provided on the side wall of the gear ring body 1. The right-angle protrusions 3 are integrally formed with the gear ring body 1. The right-angle protrusions 3 are located between two adjacent sharp teeth 2. The width of the right-angle protrusions 3 is smaller than the distance between the two adjacent sharp teeth 2. The distances between two adjacent right-angle protrusions 3 are the same.
[0026] The height of the right-angle protrusion 3 is greater than the height of the sharp tooth 2, so that the right-angle protrusion 3 can protrude from the outer side of the sharp tooth 2, and the right-angle protrusion 3 is integrally formed with the gear ring body 1.
[0027] The right-angle protrusion 3 can be matched with the straight stop 5 on the end face of the socket 4 of the press-fit pipe fitting. After the pipe fitting is pressed, the straight stop 5 on the end face of the socket 4 of the press-fit pipe fitting can abut against the right-angle protrusion 3, thereby preventing the gear ring from moving after pressing, thereby further ensuring its anti-loosening performance.
[0028] How it works
[0029] Insert the connecting pipe fitting into the socket of the compression type pipe fitting, and use the compression tool to press the toothed ring onto the connecting pipe. After the pipe fitting is compressed, the diameter of the toothed ring decreases as the inner diameter of the compression type pipe fitting decreases, thereby holding the pipe fitting tightly. The two rows of symmetrical sharp teeth on the inner surface of the toothed ring are pressed into the connecting pipe, which greatly ensures its anti-loosening performance and the parallelism of the pipeline. The right-angle protrusion on the toothed ring and the straight stop at the end of the socket of the compression type pipe fitting cooperate with each other, further ensuring its loosening performance.
[0030] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
