Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

Example one

As shown in fig. 1, a special pipe fitting, including at least one person in charge 1, person in charge 1 includes body 2 and a plurality of reinforcement 3, and a plurality of reinforcement 3 are arranged along the axial of body 2 interval in proper order, and reinforcement 3 includes pillow 31 and arc strengthening rib 32, body 2 is located between pillow 31 and arc strengthening rib 32, the one end of arc strengthening rib 32 is connected with the one end of pillow 31, the other end of arc strengthening rib 32 is connected with the other end of pillow 31, pillow 31 is equipped with the appearance groove that is used for holding body 2, the cell wall that holds the groove and the internal surface of arc strengthening rib 32 all are connected with the surface of body 2, the transversal rectangle that personally submits of pillow 31.

The reinforcement 3 is formed integrally with the pipe body 2. The reinforcement 3 is intended, on the one hand, to improve the pressure resistance of the tubular body 2 and, on the other hand, to prevent the tubular body 2 from rolling on its own. The upper end of the reinforcing part 3 is provided with an arc-shaped reinforcing rib 32, the cross section of the arc-shaped reinforcing rib 32 is semicircular, and compared with a rectangle with the same diameter, the cross section area is smaller, so that the occupied space is small. The lower extreme of reinforcement 3 is the bolster 31 of personally submitting the rectangle for the cross section, prevents effectively that body 2 from rolling by oneself to make the workman need not to utilize other instruments to restrict body 2 and roll, reach the effect that improves workman efficiency of construction.

As shown in fig. 1, a fillet 331 is arranged at a corner of the pillow block 31, and the fillet 331 is located at one end of the pillow block 31 far away from the arc-shaped reinforcing rib 32, so that the edge of the pillow block 31 is effectively prevented from scratching workers.

Example two

In this embodiment, can plug into so that the pipe fitting adapts to different use occasions to the pipe fitting. As shown in fig. 2, fig. 3, fig. 6 and fig. 7, the number of the main pipes 1 is a plurality of, all main pipes 1 are sequentially connected end to end, all main pipes 1 are provided with the connecting groove 21 and the clamping groove 22 communicated with the connecting groove 21, the connecting groove 21 and the clamping groove 22 are both located at one end of each main pipe 2, all main pipes 1 further include the connecting sleeve 4, all main pipes 1 are provided with one end of the connecting sleeve 4 rotatably connected with the other end of the main pipe 1, all main pipes 1 are provided with the other end of the connecting sleeve 4 respectively provided with the fixture block 41, and all fixture blocks 41 are connected with the clamping groove 22 after entering the adjacent main pipe 1 along the connecting groove 21 in the adjacent main pipe 1. When two main pipes 1 need to be plugged, the fixture block 41 of one main pipe 1 enters the connecting groove 21 of the other main pipe 1 and moves in the connecting groove 21 of the other main pipe 1 along the axial direction of the pipe body 2, and then the connecting sleeve 4 is rotated to enable the fixture block 41 to move along the circumferential direction of the pipe body 2 and enter the clamping groove 22, so that the connection between the two main pipes 1 is realized. When a user pulls the two adjacent main pipes 1 along the axial direction of the pipe body 2, the two main pipes 1 cannot be separated. When the two main pipes 1 need to be detached, the connecting sleeve 4 is rotated to enable the clamping block 41 to exit from the clamping groove 22, and the two main pipes 1 are pulled along the axial direction of the pipe body 2, so that the two main pipes 1 can be separated.

As shown in fig. 2 and fig. 3, the connecting sleeves 4 in all the main pipes 1 are sleeved on the periphery of the pipe 2 in the main pipe 1 and the periphery of the pipe 2 in the adjacent main pipe 1; body 2 the other end is equipped with spacing groove 23, and all be responsible for adapter sleeve 4 in 1 all is equipped with the stopper 42 that is used for stretching into this spacing groove 23 of being responsible for in 1, and stopper 42 moves along body 2's circumference in spacing groove 23, and spacing groove 23 is used for restricting stopper 42 along body 2's axial displacement to make adapter sleeve 4 enough rotate for this body 2 of being responsible for in 1, can not break away from this body 2 of being responsible for in 1 again.

As shown in fig. 3 to 5, all the main pipes 1 further include a waterproof elastic ring 5, one end of the waterproof elastic ring 5 in all the main pipes 1 is connected to the end of the pipe 2 in the main pipe 1, and the other end of the waterproof elastic ring 5 in all the main pipes 1 is used for abutting against the end of the pipe 2 in the adjacent main pipe 1. In this embodiment, the waterproof elastic ring 5 prevents water from entering the pipe body 2 from the junction of the two main pipes 1.

As shown in fig. 3 to 5, the other end of the waterproof elastic ring 5 is provided with a matching groove 51, one end of the pipe body 2 in the main pipe 1, which is far away from the waterproof elastic ring 5 in the main pipe 1, is provided with a protrusion 24, the protrusion 24 is located at the end of the main pipe 1, the protrusions 24 in the main pipe 1 are all used for interference fit with the matching groove 51 in the adjacent main pipe 1, and the waterproof performance of the pipe is further improved by tightly matching the waterproof elastic ring 5 in the main pipe 1 with the end of the main pipe 1 in the adjacent main pipe 1.

As shown in fig. 5, the free end of the projection 24 is provided with an insertion portion 25, and the cross-sectional area of the insertion portion 25 gradually decreases from the end of the insertion portion 25 close to the tube 2 in the main tube 1 to the end of the insertion portion 25 far from the tube 2 in the main tube 1. Since the fitting groove 51 needs to be interference-fitted with the projection 24, the clearance between the wall of the fitting groove 51 and the projection 24 is very small, and it is difficult for a user to insert the projection 24 into the fitting groove 51. In this embodiment, the cross-sectional area of the end of the insertion portion 25 away from the tube body 2 is smaller, so that the insertion portion can be easily inserted into the fitting groove 51, and the user can more conveniently insert the protrusion 24 into the fitting groove 51 through the insertion portion 25.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, but all the technical solutions of the present invention are within the scope of the present invention.
