DETAILED DESCRIPTION

[0028] 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.

[0029] As attached Figure 1 To Attachment Fig. 9The pipe splicing device for municipal drainage engineering shown in the figure includes a frame 1, on which a slide plate 103 is slidably installed through a slide groove 104 structure, and both the slide plate 103 and the frame 1 are provided with a clamp 3 that can clamp the pipe 4. When in use, the two pipes 4 that need to be spliced ​​are clamped by the clamp 3 respectively, and a proper spacing is reserved at the connection of the pipes 4 for installing an expansion sleeve 5. One end of the expansion sleeve 5 is sleeved on one end of the pipe 4, and the other end is inserted into one end of another pipe 4 during the movement of the slide plate 103 to expand the inner diameter of one end of the pipe 4. After expansion, it is convenient to splice the two pipes 4, and the connection of the pipe 4 is locked by tools such as a clamp. The expansion sleeve 5 is a prior art and is not used as an improved technical solution for this application. Suitable expansion sleeves 5 can be matched according to various types of pipes 4 in the market.

[0030] like Figure 1-Figure 5 As shown, two groove structures connected to the slide groove 104 are provided on the side of the frame 1, namely, the assembly groove 101 and the assembly groove 2. A toothed disc 105 is rotatably provided in the assembly groove 101. The circumferential surface of the toothed disc 105 is a disc structure and a gear structure is provided. At the same time, a rocker 102 is also provided on the circumferential surface of the toothed disc 105 structure. The rocker 102 extends from the assembly groove 101 to the outside, so that the operator can hold one end of the rocker 102. A step structure (such as Figure 4 As shown), a rack 201 structure is provided at the step structure, and the gear teeth on the toothed disc 105 can mesh with the rack 201. By holding one end of the rocker 102 to rotate the toothed disc 105, the slide plate 103 can be driven to slide in the slide groove 104, so that the pipe 4 on the slide plate 103 can move toward the direction of another pipe 4, so that the expansion sleeve 5 can open the pipe 4.

[0031] The assembly groove 101 has an axis groove 106 on the upper and lower sides, and the axis groove 106 is arranged in an arc shape as a whole (such as Figure 5 As shown in FIG. 1 , a force-bearing portion a and a retreat portion b are formed at both ends of the shaft groove 106. The upper and lower surfaces of the toothed disc 105 cooperate with the shaft groove 106 through the shaft, so that the toothed disc 105 can rotate in the shaft groove 106 through the shaft. When the rocker 102 is rotated to move the slide 103, the end of the rocker 102 is held to press the rocker 102. Figure 2 When rotating in the direction shown, the shaft on the toothed disc 105 will slide into the force-bearing part a of the shaft groove 106, and the gear teeth on the toothed disc 105 will mesh with the rack 201. Continuing to rotate the rocker 102 will allow the slide plate 103 to slide in the slide groove 104. In order to allow the slide plate 103 to continue to move at the same end, the rocker 102 is rotated in the opposite direction to allow the shaft of the toothed disc 105 to move to the retreat part b. At this time, the toothed disc 105 and the rack 201 are out of meshing, and then the rocker 102 is rotated again. The slide plate 103 can be moved continuously by repeatedly rotating in the above manner.

[0032] like Figure 2 , Figure 3 , Figure 6 As shown, in order to ensure that the slide plate 103 will not automatically reset after moving to one end, a locking rod 202 is arranged inside the frame 1 and on one side of the slide groove 104. The locking rod 202 is rotatably assembled in the assembly groove 22 through the shaft. A pawl structure is arranged at one end of the locking rod 202, and a lever 203 structure is vertically arranged at the other end. The pawl structure can be stuck in the rack 201 to limit the unidirectional movement of the slide plate 103. A spring 204 is arranged on the side of the assembly groove 22, and one end of the spring 204 contacts the side of the lever 203. In the initial state, the locking rod 202 is subjected to the force of the spring 204 on the lever 203, so that the pawl structure of the locking rod 202 is stuck in the rack 201 to prevent the slide plate 103 from automatically resetting after moving. When active resetting is required, the lever 203 is pressed to one side, the locking rod 202 rotates, and the pawl withdraws from the limit position on the rack 201, so that the slide plate 103 can be pulled to reset.

[0033] like Figure 7 and Fig. 9 As shown, in the present embodiment, the clamp 3 is specifically an upper clamping plate 301 and a lower clamping plate 302, and the upper clamping plate 301 and the lower clamping plate 302 are correspondingly provided with arc-shaped openings, and the pipe 4 can be placed in the openings. The lower clamping plate 302 is fixedly assembled on the frame 1 and the top of the slide plate 103, and the upper clamping plate 301 and the lower clamping plate 302 are connected at one end by an axis rotation, and a tension plate 303 is arranged at one end of the lower clamping plate 302 by an axis rotation, and a threaded hole is opened on the tensioning plate 303, and a bolt 304 is arranged at one end of the upper clamping plate 301, and the bolt 304 can be movable through the upper clamping plate 301 and can be screwed into the threaded hole of the tensioning plate 303, and a waist hole 305 is opened at one end of the lower clamping plate 302, and the shaft used for assembly at one end of the upper clamping plate 301 can move in the waist hole 305, so that the upper clamping plate 301 and the lower clamping plate 302 can be used to clamp pipes 4 of different diameters within a certain range.

[0034] In the implementation manner of the present application, the technical solution of the clamp 3 is not the only implementation manner, and other structures can be used to fix the pipe 4.

[0035] like Figure 1 and Figure 8 As shown, a plurality of independently rotatable rollers 7 are provided on the top surface of one end of the slide plate 103 , so as to facilitate moving a longer pipe 4 into the fixture 3 before fixing the pipe 4 .

[0036] A support bracket 6 is provided at the bottom of the rack 1. Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which can be a mechanical connection or an electrical connection, or the internal connection of two components, or a direct connection.
