Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering pipelines, and in particular relates to a tool for connecting large-diameter tongue and groove pipe joints. Background Technology

[0002] The common method for handling large-diameter tongue and groove pipe joints is to apply pipe tape. However, this method is prone to causing disturbance at the pipe joint during subsequent backfilling, resulting in horizontal displacement between the pipes. This affects the tightness of the subsequent pipes and causes water leakage at the pipe joint. Therefore, it is necessary to solve the problem of horizontal displacement between pipes caused by backfilling disturbance. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a tool for connecting large-diameter tongue and groove pipes.

[0004] This invention is achieved through the following technical solution:

[0005] A large-diameter tongue-and-groove pipe fitting tool includes a connecting ring A and a connecting ring B. The inner diameters of both connecting ring A and connecting ring B are equal to the outer diameter of the tongue-and-groove pipe. Several bendable connecting rods are evenly arranged around the outer circumference of connecting ring A. The connecting rods are divided into fixed sections and bent sections. The fixed sections are fixed to connecting ring A, and the bent sections have a locking block integrally formed downward at the end facing connecting ring B. The outer circumference of connecting ring B is evenly arranged with slots corresponding to the locking blocks. The locking blocks can be inserted into the slots to connect connecting ring A and connecting ring B together.

[0006] Preferably, the outer periphery of the connecting ring A is provided with a hoop or cable tie.

[0007] Preferably, the gap between the card block and the card slot is filled with concrete or cement mortar.

[0008] Preferably, the connecting rod is a PVC rod, a PP rod, or a PU rod.

[0009] Preferably, the fixed segment and the bent segment are hinged together.

[0010] Preferably, the fixed section and the bent section are hinged together by a hinge or a pin.

[0011] Preferably, the width of both connecting ring A and connecting ring B is 10-30cm.

[0012] This invention tool can eliminate the problem of horizontal displacement at the tongue and groove pipe joint caused by backfill disturbance. It is simple and convenient to operate, low in cost, ensures the tightness of the connection between pipes, eliminates one of the important factors that cause water leakage at the pipe joint later, and ensures the quality of pipe installation.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0020] This embodiment includes connecting ring A1 and connecting ring B2. The inner diameter of both connecting ring A1 and connecting ring B2 is equal to the outer diameter of the tongue and groove pipe. Connecting ring A1 and connecting ring B2 are respectively fitted onto the ends of the two tongue and groove pipe sections to be connected. Preferably, the width of both connecting ring A1 and connecting ring B2 is 10-30cm.

[0021] A plurality of bendable connecting rods 3 are evenly arranged around the outer periphery of the connecting ring A1. The connecting rods 3 are divided into a fixed section 4 and a bent section 5 along the width direction of the connecting ring A1. The fixed section 4 is fixed to the connecting ring A1, and the bent section 5 can be bent outwards at the connection point between the fixed section 4 and the bent section 5. Here, "outwards" refers to the direction away from the connecting ring A1. In this embodiment, the fixed section 4 and the bent section 5 of the connecting rod 3 can be made of a single, bendable material, as shown in the attached figure. Figure 4 As shown, for example, connecting rod 3 can be a PVC rod, PP rod, or PU rod, etc. PVC (polyvinyl chloride), PP (polypropylene), PU (polyurethane), and other materials all have good bendability, allowing the bent section 5 to be pressed against connecting ring A1 so that it is on the same plane as the fixed section 4. In this embodiment, the fixed section 4 and the bent section 5 of connecting rod 3 can also be hinged, as shown in the attached figure. Figure 5As shown, the fixed section 4 and the bent section 5 are hinged together by a hinge 9 or a pin, etc. The bent section 5 can be rotated outward at the hinge point to bend. When the hinge method is used, the fixed section 4 and the bent section 5 of the connecting rod 3 can be made of plastic or metal.

[0022] A locking block 6 is integrally formed and downwardly positioned at the end of the bent section 5 of the connecting rod 3 facing the connecting ring B2. A corresponding locking groove 7 is evenly distributed around the outer circumference of the connecting ring B2. When the connecting rings A1 and B2 come into contact, the locking block 6 can be precisely engaged into the locking groove 7, connecting the connecting rings A1 and B2 together. In this embodiment, four connecting rods 3 are provided, evenly distributed around the connecting ring A1. Four corresponding locking grooves 7 are also provided on the connecting ring B2. The locking grooves 7 do not penetrate the connecting ring B2, and their dimensions match the locking block 6, allowing the locking block 6 to be precisely embedded within the locking groove 7. To prevent the locking block 6 from slipping out of the locking groove 7, it is preferable to fill the gap between the locking block 6 and the locking groove 7 with concrete or cement mortar.

[0023] To further ensure the stability of the tool, it is preferable to provide a ring clamp 8 or cable tie on the outer periphery of the connecting ring A1. The ring clamp 8 is used to firmly fix the connecting ring A1 and the connecting rod 3 on it to the tongue and groove pipe. Alternatively, cable ties, such as common nylon cable ties, can also be used.

[0024] In use, before connecting two tongue-and-groove pipe sections, first slip connecting ring A1 and connecting ring B2 onto the two pipe sections respectively. After connecting the two pipe sections, move connecting rings A1 and B2 to the corresponding joints of the pipe sections, aligning them together. While moving them, you can use a tool to gently tap connecting rings A1 and B2 horizontally to gradually move them to the outer edge of the joint. Once connecting rings A1 and B2 are aligned, then... Press down on the bent section 5 of the connecting rod 3, making the bent section 5 and the fixed section 4 on the same horizontal plane. At this time, the locking block 6 at the end of the bent section 5 just fits into the slot 7 on the connecting ring B2. Then, the connecting ring A1 and the connecting ring B2 are connected together by the connecting rod 3. Then, concrete or cement mortar is poured into the gap between the locking block 6 and the slot 7, thereby connecting the two tongue and groove pipes together. Then, a ring hoop 8 or binding strap is fixed to the outer circumference of the connecting ring A1 to firmly fix the connecting ring A1 to the tongue and groove pipe. Finally, backfilling is performed. The tool of this invention is a disposable tool and is buried in the backfill soil along with the tongue and groove pipe. After installing the tool of this invention, the connected tongue and groove pipes are unlikely to have relative horizontal displacement, which greatly improves the leakage problem at the pipe and pipe joint caused by horizontal displacement.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
