Technical Field

[0001] The utility model relates to the technical field of protection devices, in particular to a protection device for a pipe joint. Background Art

[0002] A pipe joint protector is a device or structure designed to protect pipe joints from damage or external factors. This device can ensure the stability and safety of pipe joints, thereby extending the service life of the pipeline system.

[0003] During use, the existing pipe joint protection device can protect the joints of the pipes, but it is not convenient to install the protection shell, resulting in a lot of time required for installation. At the same time, the protection effect on the pipes is not good, resulting in damage to the pipes after the protection shell is squeezed, thereby reducing the convenience of installation and protection of the traditional pipe joint protection device. For this reason, a pipe joint protection device is introduced. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The protective device for the pipe joint, when installing the protective shell, the staff rotates the limit block to make the threaded rod and the inner wall of the threaded groove threadedly connected, and at the same time the limit block is vertically limited at the notch of the limit groove, and then the rotating plate is rotated to make the rotating plate rotate on the outer wall of the rotating column.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 A protective device for a pipe joint includes a pipe 1, a protective shell 2 is provided on the top of the pipe 1, a limiting groove 4 and a clamping groove 12 are respectively provided on the top of the protective shell 2, a threaded groove 13 is provided on the top of the pipe 1, an installation component 3 is provided on the inner wall of the limiting groove 4, and a fixing rod 6 and a spring 7 are respectively fixedly assembled inside the protective shell 2.

[0023] It should be noted that the installation component 3 is limited by the limiting groove 4 and the clamping groove 12 to prevent the installation component 3 from being offset as a whole during the placement process, causing the protective shell 2 to fall during the placement process and damage the pipe 1. The protective plate 5 is limited by the fixing rod 6 so that the protective plate 5 can only work at one height.

[0024] In a preferred embodiment, the outer wall of the fixed rod 6 is slidably connected to a moving block 8, the outer wall of the moving block 8 is fixedly equipped with a fixed block 9, the inner wall of the fixed block 9 is rotatably connected to a rotating rod 10, the outer wall of the rotating rod 10 is fixedly equipped with one end of an extrusion rod 11, and the other end of the extrusion rod 11 is fixedly equipped with a protective plate 5.

[0025] It should be noted that when the protective shell 2 is squeezed, pressure is applied to the protective plate 5 to make it move backward, thereby driving the extrusion rod 11 to rotate on the outer wall of the rotating rod 10, and pressure is applied to the moving block 8 through the rotating rod 10 to make the moving block 8 slide on the outer wall of the fixed rod 6. When the moving block 8 applies pressure to the spring 7, the elastic potential energy of the spring 7 is released, thereby realizing the buffering effect of the protective plate 5 on the pipe 1. During the buffering process, the protective plate 5 protects the pipe 1 to prevent the protective shell 2 from directly colliding with the pipe 1, thereby reducing the service life of the pipe 1.

[0026] In a preferred embodiment, the mounting assembly 3 includes a threaded rod 301, a limit block 302 is fixedly assembled on the top of the threaded rod 301, a placement block 303 is fixedly assembled on the top of the limit block 302, the inner wall of the placement block 303 is rotatably connected to a rotating column 304, the outer wall of the rotating column 304 is fixedly assembled with one end of a rotating plate 305, and the other end of the rotating plate 305 is fixedly assembled with a clamping block 306 on the bottom.

[0027] It should be noted that when installing the protective shell 2, the staff needs to ensure that the threaded rod 301 is tightly connected to the inner wall of the threaded groove 13 by rotating the limit block 302 component. At the same time, it is necessary to ensure that the limit block 302 is vertically placed in the notch of the limit groove 4 to achieve an effective limiting effect. Subsequently, by rotating the rotating plate 305 component, it is made to perform a circular motion on the outer wall of the rotating column 304. When the rotating plate 305 rotates to the top position of the snap-in groove 12, a certain downward pressure needs to be applied to the rotating plate 305 so that the snap-in block 306 is firmly snap-fitted with the inner wall of the snap-in groove 12, thereby achieving the limiting fixation of the limit block 302. Through the above steps, the protective shell 2 can be quickly installed.

[0028] In a preferred embodiment, the threaded rod 301 is threadedly connected to the threaded groove 13 , and the clamping block 306 is clamped to the inner wall of the clamping groove 12 .

[0029] It should be noted that the connection between the pipe 1 and the protective shell 2 is achieved by threading the threaded rod 301 and the threaded groove 13 , and the position limiting of the limit block 302 is achieved by the clamping block 306 and the clamping groove 12 .

[0030] In a preferred embodiment, the spring 7 is fixedly assembled with the moving block 8 , and the limiting block 302 is matched with the inner wall of the limiting groove 4 .

[0031] It should be noted that the spring 7 and the moving block 8 are fixedly assembled so that the spring 7 will not separate from the outer wall of the fixed rod 6 when releasing the elastic potential energy, and the limit block 302 is limited by adapting the limit block 302 to the inner wall of the limit groove 4.

[0032] In a preferred embodiment, there are four groups of mounting components 3 , and the four groups of mounting components 3 are respectively located on the top of the protective shell 2 .

[0033] It should be noted that, by using four sets of mounting components 3, a more stable connection between the pipe 1 and the protective shell 2 is achieved, thereby preventing the protective shell from falling off from the top of the pipe 1 twice.

[0034] Working principle: when the protective shell 2 is squeezed, the protective plate 5 applies pressure to the pipe 1, so that the protective plate 5 drives the squeezing rod 11 to rotate on the outer wall of the rotating rod 10 during the backward movement, and then applies pressure to the moving block 8 through the rotating rod 10, so that the moving block 8 slides on the outer wall of the fixed rod 6. When the moving block 8 applies pressure to the spring 7, the elastic potential energy of the spring 7 is released, so that the protective plate 5 buffers the pipe 1, protects the pipe 1 from direct collision with the protective shell 2, and prevents the pipe 1 from being damaged, thereby extending its service life. When installing the protective shell 2, the operator rotates the limit block 302 to make the threaded rod 301 threadedly connected to the inner wall of the threaded groove 13, and at the same time, the limit block 302 is vertically placed in the notch of the limit groove 4 for positioning, and then the rotating plate 305 is rotated to make it rotate on the outer wall of the rotating column 304. When the rotating plate 305 is rotated to the top of the snap-in groove 12, it is pressed to make the snap-in block 306 snap-in to the inner wall of the snap-in groove 12, thereby achieving the limit fixation of the limit block 302, thereby achieving the quick installation of the protective shell 2.

[0035] 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.
