[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

Figure 3 This utility model Figure 2 A magnified view of the local structure at point A, Figure 4 It is a partial structural diagram of the utility model.

[0020] The utility model provides a snap-fit groove pipe structure, including a groove pipe body 101, a snap-fit pipe 102, two snap-fit components and a rubber ring 103, each of the snap-fit components including an insertion rod 104, a shell 105, a limiting rod 106, a spring 107, a ring 108, a fixing plate 109, a slide rail 110, a slider 111 and a handle 112, the fixing plate 109 has a limiting hole 113, the upper end of the snap-fit pipe 102 has two slide grooves 114, the upper end of the snap-fit pipe 102 has a groove 115, the lower end of the limiting rod 106 has a beveled surface 116, and the groove 115 has an annular groove 117.

[0021] When the locking rod 104 is in the innermost position of the slot 114, the locking rod 106 is released, and the locking rod 106 is driven back to its original position by the elastic force of the spring 107, and fits into the limiting hole 113, thereby limiting the slot tube body 101, so that the locking rod 104 is always fixed in the corresponding slot 114, thereby connecting the locking tube 102 and the slot tube body 101, thereby the device can stably connect the two tubes, and the operation is simple and convenient for the staff to operate; when the limiting rod 106 moves, the slider 111 and the slide rail 110 cooperate to make the locking rod 106 move back to the innermost position of the slot 114. The limit rod 106 is more stable when moving, making it more accurately adapted to the limit hole 113; through the setting of the beveled surface 116, when the groove tube body 101 and the insertion rod 104 are rotated, there is no need to pull the limit rod 106 upward, only the beveled surface 116 is required to press against the fixing plate 109, thereby pushing the limit rod 106 to move upward, and then the limit rod 106 can adapt to the limit hole 113; when the groove tube body 101 and the engaging tube fitting 102 are to be disassembled, the pull handle 112 is used to facilitate pulling the limit rod 106 upward, thereby canceling the adaptation of the limit rod 106 to the limit hole 113, thereby facilitating the disassembly and separation of the groove tube body 101 and the engaging tube fitting 102; through the setting of the rubber ring 103, the sealing effect of the device is improved.

[0022] Among them, the insertion rod 104 is fixedly connected to the lower end of the groove tube body 101, the shell 105 is fixedly connected to the outer wall of the groove tube body 101, the insertion rod 104 is slidably adapted to the corresponding slide groove 114, the groove tube body 101 is adapted to the groove 115, the fixing plate 109 is fixedly connected to the outer wall of the locking tube 102, the limiting rod 106 passes through the shell 105 and is adapted to the limiting hole 113, the ring 108 is fixedly sleeved on the outside of the limiting rod 106 and is located inside the shell 105, and the two ends of the spring 107 are respectively fixedly connected to the inner wall of the shell 105 and the ring 108. When engaging, the insertion rod 104 is inserted into the corresponding sliding groove 114, and then the insertion rod 104 is rotated and the limiting rod 106 is pulled upward. When the insertion rod 104 is rotated to the innermost part of the sliding groove 114, the limiting rod 106 is released, and then under the elastic force of the spring 107, the limiting rod 106 is driven to return to its original position and adapt to the limiting hole 113, thereby limiting the groove pipe body 101, so that the insertion rod 104 is always fixed in the corresponding sliding groove 114, thereby connecting the engaging pipe fitting 102 and the groove pipe body 101. In this way, the device can stably connect the two pipe fittings, and the operation is simple, which is convenient for the staff to operate.

[0023] Secondly, the slide rail 110 is fixedly connected to the inner wall of the housing 105, one end of the slider 111 is slidably adapted to the slide rail 110, and the other end of the slider 111 is fixedly connected to the limiting rod 106. When the limiting rod 106 moves, the cooperation between the slider 111 and the slide rail 110 makes the limiting rod 106 move more stably and more accurately adapted to the limiting hole 113.

[0024] At the same time, the lower end of the limiting rod 106 has a beveled surface 116, and the beveled surface 116 is located at the lower end of the limiting rod 106. Due to the provision of the beveled surface 116, when the slot tube body 101 and the insertion rod 104 rotate, there is no need to pull the limiting rod 106 upward. Instead, the beveled surface 116 can be pressed against the fixing plate 109 to push the limiting rod 106 upward, and then the limiting rod 106 can adapt to the limiting hole 113.

[0025] In addition, the pull handle 112 is fixedly connected to the upper end of the limiting rod 106. When the trough tube body 101 and the engaging tube 102 are to be disassembled, the pull handle 112 facilitates pulling the limiting rod 106 upward, thereby canceling the engagement of the limiting rod 106 with the limiting hole 113, thereby facilitating the disassembly and separation of the trough tube body 101 and the engaging tube 102.

[0026] Furthermore, the groove 115 has an annular groove 117, the rubber ring 103 fits into the annular groove 117, and the upper end of the rubber ring 103 contacts the lower end of the groove tube body 101. The provision of the rubber ring 103 improves the sealing effect of the device.

[0027] When the locking rod 104 is in the innermost position of the slot 114, the locking rod 106 is released, and the locking rod 106 is driven back to its original position by the elastic force of the spring 107, and fits into the limiting hole 113, thereby limiting the slot pipe body 101, so that the locking rod 104 is always fixed in the corresponding slot 114, thereby connecting the locking pipe 102 and the slot pipe body 101. In this way, the device can stably connect the two pipes, and the operation is simple and convenient for the staff to operate. When the limiting rod 106 moves, the slider 111 and the slide rail 110 can be used to lock the locking rod 106. The cooperation makes the limit rod 106 more stable when moving, and makes it more accurately adapt to the limit hole 113; through the setting of the beveled surface 116, when the groove tube body 101 and the insertion rod 104 are rotated, there is no need to pull the limit rod 106 upward, only the beveled surface 116 is required to press against the fixing plate 109, thereby pushing the limit rod 106 to move upward, and then the limit rod 106 can adapt to the limit hole 113; when the groove tube body 101 and the engaging tube fitting 102 are to be disassembled, the pull handle 112 is used to facilitate the pulling of the limit rod 106 to move upward, so that the limit rod 106 cancels the adaptation with the limit hole 113, thereby facilitating the disassembly and separation of the groove tube body 101 and the engaging tube fitting 102; through the setting of the rubber ring 103, the sealing effect of the device is improved.
