Description

Technical Field

[0001] This utility model relates to the field of steel-plastic composite pipe technology, and in particular to a steel-plastic composite pipe that is easy to connect. Background Technology

[0002] Steel-plastic composite pipe is a composite pipe material that combines the high strength of steel with the corrosion resistance of plastic. It is made by combining steel pipes with plastic layers. When the composite pipes are connected, they can be easily connected by fixing them with flanges. However, the length of each composite pipe is fixed when they are connected, so the overall length after the connection cannot be increased, which cannot meet the installation requirements when connecting. Utility Model Content

[0003] The main purpose of this utility model is to provide a steel-plastic composite pipe that is easy to connect, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A steel-plastic composite pipe that is easy to connect includes a first composite pipe and a second composite pipe. A fixed flange is fixedly fitted on the surface of the first composite pipe and the second composite pipe at one end, and a movable flange is movably fitted on the surface of the first composite pipe and the second composite pipe at the other end. A bolt and nut assembly is installed between the movable flange of the first composite pipe and the fixed flange of the second composite pipe. Fasteners are embedded at the upper and lower rear ends of the movable flange.

[0005] More preferably, an annular embedding groove is formed inside one end of the first composite pipe and the second composite pipe, and a clamping plate is fixedly installed on the upper and lower surfaces of the other end of the first composite pipe and the second composite pipe. A stop block is fixedly installed on one end surface of the clamping plate, and a threaded groove is formed on the upper surface of the clamping plate. A connecting pipe is fixedly installed on the other end surface of the first composite pipe and the second composite pipe.

[0006] More preferably, the inner surface of the movable flange has grooves on the top and bottom, and the rear surface of the movable flange has a retainer fixedly installed on the top and bottom. The upper surface of the retainer has a socket, and the number of sockets is several.

[0007] More preferably, the ferrule is fitted onto the ferrule plate, the fastener passes through the insertion hole and is embedded in the threaded groove, and the connecting pipe of the first composite pipe is embedded in the annular embedding groove of the second composite pipe.

[0008] Compared with the prior art, this utility model proposes a steel-plastic composite pipe that is easy to connect, and has the following beneficial effects: In this invention, by setting up a first composite pipe, a second composite pipe, a movable flange, and fasteners in a cooperative manner, the overall length of the first and second composite pipes after docking is adjustable. By moving the movable flange forward a certain distance, the fastener is inserted into a threaded groove through a socket, thus limiting the movement of the movable flange. Since the movable flange is not flush with the end of the first composite pipe, when the movable flange of the first composite pipe and the fixed flange of the second composite pipe are fixed together by the bolt and nut assembly, the docking pipe can be embedded into the annular groove to a certain depth. This ensures that the sum of the lengths of the first and second composite pipes after docking is greater than or equal to the original sum of the lengths of the first and second composite pipes.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0013] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0014] like Figure 1-3As shown, a steel-plastic composite pipe that is easy to connect includes a first composite pipe 1 and a second composite pipe 2. A fixed flange 3 is fixedly sleeved on the surface of the first composite pipe 1 and the second composite pipe 2 at one end. A movable flange 4 is movably sleeved on the surface of the first composite pipe 1 and the second composite pipe 2 at the other end. A bolt and nut assembly 5 is installed between the movable flange 4 of the first composite pipe 1 and the fixed flange 3 of the second composite pipe 2. Fasteners 6 are embedded at the upper and lower rear ends of the movable flange 4.

[0015] In a preferred embodiment: an annular embedding groove 104 is provided inside one end of composite pipe 1 and composite pipe 2; a clamping plate 101 is fixedly installed on the upper and lower surfaces of the other end of composite pipe 1 and composite pipe 2; a stop block 102 is fixedly installed on one end surface of clamping plate 101; a threaded groove 103 is provided on the upper surface of clamping plate 101; and a connecting pipe 105 is fixedly installed on the other end surface of composite pipe 1 and composite pipe 2.

[0016] In the above structure, when the movable flange 4 moves on the clamping plate 101, the baffle 102 restricts the distance that the movable flange 4 moves backward.

[0017] In a preferred embodiment: the inner surface of the movable flange 4 is provided with grooves 401 at the top and bottom, and the rear surface of the movable flange 4 is fixedly installed with a ferrule 402 at the top and bottom. The upper surface of the ferrule 402 is provided with a socket 403, and the number of sockets 403 is several.

[0018] In a preferred embodiment: the sleeve 402 is fitted onto the card plate 101, the fastener 6 passes through the insertion hole 403 and is embedded in the threaded groove 103, and the connecting pipe 105 of the first composite pipe 1 is embedded in the annular embedding groove 104 of the second composite pipe 2.

[0019] In the above structure, the cooperation between the ferrule 402 and the clamping plate 101 allows the movable flange 4 to maintain linear movement during movement, and the fastener 6 can limit the movable flange 4 when it is embedded in different insertion holes 403.

[0020] When this utility model is in use, during the docking process of composite pipe 1 and composite pipe 2, the overall length of composite pipe 1 and composite pipe 2 after docking is adjustable. By moving the movable flange 4, the movable flange 4 moves forward a certain distance, and then the fastener 6 is inserted into the threaded groove 103 through a hole 403. This can limit the movement of the movable flange 4. Since the movable flange 4 is not flush with the end of composite pipe 1, when the movable flange 4 of composite pipe 1 and the fixed flange of composite pipe 2 are fixed together by the bolt and nut assembly 5, the docking pipe 105 can be embedded into the annular groove 104 to a certain depth. Furthermore, the sum of the lengths of composite pipe 1 and composite pipe 2 after docking is greater than the sum of their original lengths.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
