Description

Technical Field

[0001] This utility model relates to the field of equal diameter joint technology, and in particular to a composite equal diameter joint that is easy to install. Background Technology

[0002] An equal-diameter fitting is a pipe connector with both ends having the same outer or inner diameter (it's more common to say the outer diameter is the same, especially in pipe fitting naming). Its main function is to connect two pipes of identical diameter in a piping system, allowing fluid to flow smoothly from one pipe to another without changing the pipe's diameter. These fittings are typically right-angled (elbows) or at a certain angle, used to change the direction of the pipe while maintaining its nominal size, and are widely used in various fluid transport systems.

[0003] In existing pipe connection technologies, traditional composite equal-diameter fittings are widely used to connect two pipe sections of the same diameter. However, their operation has significant shortcomings. During use, operators typically need to tighten the threads of the fastening sleeves connected to the ends of both pipe sections separately. This process is not only cumbersome, requiring the operator to apply force to both components simultaneously or sequentially, but also time-consuming and labor-intensive due to the high tightening torque required for threaded connections. This reduces the efficiency of pipe installation and maintenance, especially in situations with limited space or frequent disassembly and assembly. Utility Model Content

[0004] One objective of this invention is to provide a composite equal-diameter joint that is easy to install. This invention addresses the issue mentioned in the background that, during use, operators typically need to tighten the threads of the fastening sleeves connected to the ends of the two pipe sections separately. This process is not only cumbersome, requiring the operator to apply force to both components simultaneously or sequentially, but also time-consuming and labor-intensive due to the large tightening torque required by the threaded connection itself. This reduces the efficiency of pipe installation and maintenance, especially in situations where space is limited or frequent disassembly and assembly are required.

[0005] A composite equal-diameter connector for easy installation according to an embodiment of the present invention includes a connector mechanism, a locking mechanism, and an anti-reverse mechanism. The connector mechanism includes a connector body and a connecting sleeve. The connecting sleeve is slidably installed on both sides of the surface of the connector body. The locking mechanism includes a locking block and an L-shaped top block. The L-shaped top block is fixedly installed on the inner side of the connecting sleeve, and the locking block is movably installed on the inner side of the connector body. The anti-reverse mechanism includes a first gear, a second gear, and a rotating rod. The rotating rod is rotatably installed inside the connector body. The first gear is fixedly installed at both ends of the rotating rod, and the second gear is fixedly installed on the outer surface of the first gear. A rack is fixedly installed on the inner side of the connecting sleeve.

[0006] Preferably, a fixing ring is fixedly installed on the side surface of the connector body, a limiting groove is formed on the outer surface of the connector body, a limiting block is slidably installed inside the limiting groove, and the inner surface of the connecting sleeve is fixedly installed on the limiting block.

[0007] Preferably, the inner surface of the connector body is provided with a groove, and the locking block is rotatably mounted inside the groove via a rotating shaft.

[0008] Preferably, a first spring is installed between the outer surface of the locking block and the inner wall of the groove, and a locking tooth is fixedly installed on the inner surface of the locking block.

[0009] Preferably, one side surface of the locking block and one end of the L-shaped top block are provided with inclined surfaces. When the L-shaped top block slides toward the locking block, the L-shaped top block presses the locking block inward through the inclined surfaces.

[0010] Preferably, a knob is fixedly installed on the outer surface of the second gear to facilitate manual rotation of the first and second gears.

[0011] Preferably, the second gear meshes with the rack, and when the second gear rotates, it drives the rack to make horizontal sliding motion through the meshing relationship.

[0012] Preferably, a locking block is rotatably mounted on the outer surface of the connector body, and a second spring is installed between one side surface of the locking block and one side surface of the fixing ring.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a locking mechanism and an anti-reverse mechanism. When not in use, the locking block is held inside the groove by a first spring, preventing the locking teeth from interfering with pipe insertion and removal. When two pipe sections need to be joined using a composite equal-diameter connector, the pipes to be joined are inserted into the connector body. Turning the knob of the anti-reverse mechanism counterclockwise causes the second gear to rotate counterclockwise. The second gear drives the racks and connecting sleeves on both sides to slide synchronously towards the center. Releasing the knob uses the spring force of the second spring to lock the locking block into the groove of the first gear, preventing the first gear from reversing and causing damage to the connection between the two sides. The sleeve slides outward, allowing it to slide and lock only towards the center. As the connecting sleeve slides towards the center, the inclined surface of the L-shaped top block contacts the inclined surface of the locking block. As the L-shaped top block slides inward, the inclined surface forces the locking block to rotate downward around the axis of rotation. The locking teeth at the lower end of the locking block insert into the outer surface of the pipe, locking the position of the pipe until the connecting sleeve slides inward to its limit and the locking teeth are completely submerged in the outer wall of the pipe, thus connecting the two pipe sections. This simplifies pipe connection, eliminates the need for tightening threads, saves effort and is highly efficient, and provides a secure lock after connection, improving installation efficiency.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] refer to Figure 1-5A composite equal-diameter joint that is easy to install includes a joint mechanism 1, a locking mechanism 2, and an anti-reverse mechanism 3. The joint mechanism 1 includes a joint body 101 and a connecting sleeve 102, which is slidably mounted on both sides of the surface of the joint body 101. The locking mechanism 2 includes a locking block 203 and an L-shaped top block 205, which is fixedly mounted on the inner side of the connecting sleeve 102 and movably mounted on the inner side of the joint body 101. The anti-reverse mechanism 3 includes a first gear 302, a second gear 305, and a rotating rod 301, which rotates... Installed inside the connector body 101, both ends of the rotating rod 301 are fixedly mounted with a first gear 302, and a second gear 305 is fixedly mounted on the outer surface of the first gear 302. A rack 307 is fixedly mounted on the inner side of the connecting sleeve 102. Through the locking mechanism 2 and the anti-reverse mechanism 3, when not in use, the locking block 203 is kept inside the groove 201 by the first spring 206. The locking teeth 204 will not affect the insertion and removal of the pipe. When two pipe sections need to be spliced ​​together through the composite equal diameter connector, the pipes to be spliced ​​are inserted into the connector body. After the inner side of body 101 is closed, the knob 306 of the anti-reverse mechanism 3 is rotated counterclockwise, causing the second gear 305 to rotate counterclockwise. The second gear 305 drives the racks 307 on both sides and the connecting sleeve 102 to slide synchronously towards the middle. When the knob 306 is released, the elastic force of the second spring 304 locks the locking block 303 into the tooth groove of the first gear 302, preventing the first gear 302 from reversing and causing the connecting sleeves 102 on both sides to slide outward. This ensures that the sliding sleeve can only slide towards the middle and locks it in place. During the process of the connecting sleeve 102 sliding towards the middle, the L-shaped top block 20... The inclined surface of the tip of the L-shaped top block 205 contacts the inclined surface on one side of the locking block 203. As the L-shaped top block 205 slides inward, the inclined surface presses the locking block 203 downward around the rotating shaft 202. The locking teeth 204 at the lower end of the locking block 203 are inserted into the outer surface of the pipe to lock the position of the pipe until the connecting sleeve 102 slides inward to its limit and the locking teeth 204 are completely submerged in the outer wall of the pipe, thus connecting the two sections of the pipe. This simplifies the pipe connection, eliminates the need to tighten threads, saves effort and is efficient, and ensures a stable lock after connection, improving installation efficiency.

[0024] Example 1: A fixing ring 103 is fixedly installed on the side surface of the connector body 101. A limiting groove 104 is opened on the outer surface of the connector body 101. A limiting block 105 is slidably installed inside the limiting groove 104. The inner surface of the connecting sleeve 102 is fixedly installed on the limiting block 105. A groove 201 is opened on the inner surface of the connector body 101. A locking block 203 is rotatably installed on the inner side of the groove 201 via a rotating shaft 202. A first spring 206 is installed between the outer surface of the locking block 203 and the inner wall of the groove 201. A locking tooth 204 is fixedly installed on the inner surface of the locking block 203. A slope is provided on one side surface of the locking block 203 and one end of the L-shaped top block 205. When the L-shaped top block 205 slides toward the locking block 203, the L-shaped top block 205 presses the locking block 203 inward through the slope.

[0025] Example 2: A knob 306 is fixedly installed on the outer surface of the second gear 305 to facilitate manual rotation of the first gear 302 and the second gear 305. The second gear 305 meshes with the rack 307. When the second gear 305 rotates, it drives the rack 307 to make horizontal sliding motion through the meshing relationship. A locking block 303 is rotatably installed on the outer surface of the connector body 101. A second spring 304 is installed between one side surface of the locking block 303 and one side surface of the fixing ring 103.

[0026] When not in use, the locking block 203 inside the connector body 101 is positioned inside the groove 201 under the action of the first spring 206. The locking teeth 204 on it do not obstruct the insertion and removal of the pipe, ensuring operational flexibility. When two pipe sections need to be connected, they are first inserted into the inner side of the connector body 101 respectively. Then, the operator rotates the knob 306 of the anti-reverse mechanism 3 counterclockwise. This action drives the second gear 305 to rotate counterclockwise as well. The meshing relationship between the second gear 305 and the racks 307 on both sides causes the racks 307 to drive the connecting sleeve 102 to slide synchronously towards the center. During the sliding of the connecting sleeve 102 towards the center, the tip of the L-shaped top block 205 on its inner side will contact the inclined surface on one side of the locking block 203. As the L-shaped top block 205 continues to slide inward, The sliding and inclined plane forces the locking block 203 downward around the rotating shaft 202, causing the locking teeth 204 at the lower end of the locking block 203 to insert into the outer surface of the pipe, initially locking the pipe position. After the operator releases the knob 306, the elasticity of the second spring 304 will cause the locking block 303 to be locked in the tooth groove of the first gear 302, effectively preventing the first gear 302 from reversing and avoiding the connecting sleeve 102 from sliding outward. This ensures that the connecting sleeve 102 can only slide stably towards the center to lock. The connecting sleeve 102 continues to slide inward until it reaches the limit position. At this time, the locking teeth 204 are completely submerged in the outer wall of the pipe, and the two pipe sections are firmly connected. Throughout the process, there is no need for tedious thread tightening operations, making the operation labor-saving and efficient. After connection, the locking is stable, greatly improving the efficiency of pipe installation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
