Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a pipe connection sealing clamp that is easy to fix. Background Technology

[0002] Pipe clamps, as a key pipe connection device, are widely used in industrial production, municipal engineering, and household water supply and drainage.

[0003] When connecting pipe joints, the operator is required to alternately tighten the locking bolts and nuts on both sides of the pipe joint. This process is not only cumbersome, but also makes it difficult to ensure that the locking bolts on both sides of the joint reach the same tightening force, which affects the sealing performance of the clamp.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a pipe connection sealing clamp that is easy to fix in order to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a pipe connection sealing clamp that is easy to fix, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pipe connection sealing clamp for easy fixation includes a lower clamp, an upper clamp, a sealing ring, a chamfer, a lower connecting block, and an upper connecting block. One end of the lower clamp is hinged to the upper clamp. Sealing rings are provided on the inner walls of the lower and upper clamps. The other end of the upper clamp is fixedly connected to the upper connecting block, and the other end of the lower clamp is fixedly connected to the lower connecting block. The lower connecting block has multiple second sliding grooves, and the lower and upper connecting blocks have multiple first sliding grooves, which communicate with the corresponding second sliding grooves. Locking blocks are slidably connected in each of the first sliding grooves. Abutment plates are fixedly connected to the upper ends of each locking block. A slot is provided on the end faces of the locking blocks that are close to each other. A locking block is slidably connected in each of the second sliding grooves, and the locking block is slidably connected to the inner wall of the slot. A connecting component is provided between two locking blocks. The connecting component is used to control the synchronous movement of multiple locking blocks, and a thrust component is provided on the connecting component.

[0008] A further technical solution is that the upper hoop and the upper connecting block are an integral structure, the lower hoop and the lower connecting block are an integral structure, and the locking block and the abutment plate are an integral structure.

[0009] A further technical solution involves chamfering at one end of each card block.

[0010] In a further technical solution, the connecting component includes a connecting groove, a transition groove, a transition plate, and a sliding plate; the lower connecting block has a connecting groove and a transition groove, and the connecting groove is connected to the second sliding groove through the transition groove. The inner wall of the connecting groove is slidably connected to the sliding plate, and the inner wall of the transition groove is slidably connected to the transition plate. The two ends of the transition plate are respectively fixedly connected to the sliding plate and the locking block.

[0011] A further technical solution involves integrating the card block, transition plate, and slide plate into a single structure.

[0012] A further technical solution includes a threaded shaft, a placement groove, a spring, and a handle; the threaded shaft is threadedly connected to the slide plate, one end of the threaded shaft is fixedly connected to the handle, and the other end of the threaded shaft is rotatably connected to the inner wall of the connecting groove near the lower hoop; a plurality of evenly distributed placement grooves are provided at one end of the slide plate near the lower hoop, and a spring is provided in the placement groove, with the other end of the spring fixedly connected to the inner wall of the connecting groove near the lower hoop.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. The sliding plate is driven by the thrust assembly to slide along the inner wall of the connecting groove. Then, the sliding plate drives the locking block to slide along the inner wall of the second sliding groove through the transition plate. Then, the end of the locking block with a chamfer reaches the position of the locking groove. As the locking block continues to slide, the end of the locking block with a chamfer is locked into the inner wall of the locking groove. While sliding along the inner wall of the locking groove, it drives the locking block to descend. Then, the locking block drives the abutment plate to descend and press the upper connecting block and the lower connecting block until the chamfer is disengaged from the inner wall of the locking groove. At this time, the lower connecting block and the upper connecting block are firmly fixed, which can effectively control the tightening force of the abutment plate on both sides of the lower connecting block and the upper connecting block to be the same. The operation is simple.

[0015] 2. The spring always applies an elastic force towards the lower clamp to the slide plate, making it easier to rotate the throttle and reducing the force between the threaded shaft and the slide plate. This effectively alleviates thread wear between the threaded shaft and the slide plate, thereby extending the service life.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figure 1-6As shown in the figure, this utility model embodiment provides a pipe connection sealing clamp that is easy to fix, including a lower clamp 1, an upper clamp 2, a sealing ring 3, a chamfer 4, a lower connecting block 7, and an upper connecting block 8. One end of the lower clamp 1 is hinged to the upper clamp 2. The inner walls of the lower clamp 1 and the upper clamp 2 are provided with sealing rings 3. The other end of the upper clamp 2 is fixedly connected to the upper connecting block 8, and the other end of the lower clamp 1 is fixedly connected to the lower connecting block 7. The lower connecting block 7 has a plurality of second sliding grooves 11, and the lower connecting block 7 and the upper connecting block 8 have a plurality of first sliding grooves 9, and the first sliding grooves 9 and the corresponding first sliding grooves 11 are connected to each other. Two sliding grooves 11 are connected. Locking blocks 10 are slidably connected in the first sliding groove 9. Abutment plates 14 are fixedly connected to the upper end of each locking block 10. A slot 13 is opened on the end face of each locking block 10 that is close to each other. A locking block 6 is slidably connected in the second sliding groove 11. The locking block 6 is slidably connected to the inner wall of the slot 13. A connecting component 12 is provided between the two locking blocks 6. The connecting component 12 is used to control the synchronous movement of multiple locking blocks 6. A thrust component 5 is provided on the connecting component 12. The thrust component 5 is used to drive the connecting component 12 to move.

[0027] Furthermore, the upper hoop 2 and the upper connecting block 8 are an integral structure, the lower hoop 1 and the lower connecting block 7 are an integral structure, and the locking block 10 and the abutment plate 14 are an integral structure.

[0028] Furthermore, each end of the card block 6 is provided with a chamfer 4, which is used to facilitate the insertion of the card block 6 into the inner wall of the card slot 13, while driving the locking block 10 to descend.

[0029] like Figure 2-6 As shown, the connecting component 12 includes a connecting groove 1201, a transition groove 1202, a transition plate 1203, and a sliding plate 1204; the lower connecting block 7 is provided with a connecting groove 1201 and a transition groove 1202, and the connecting groove 1201 is connected to the second sliding groove 11 through the transition groove 1202. The sliding plate 1204 is slidably connected to the inner wall of the connecting groove 1201, and the transition plate 1203 is slidably connected to the inner wall of the transition groove 1202. The two ends of the transition plate 1203 are fixedly connected to the sliding plate 1204 and the locking block 6, respectively.

[0030] Furthermore, the card block 6, the transition plate 1203, and the slide plate 1204 are an integrated structure.

[0031] Specifically, the thrust assembly 5 drives the slide plate 1204 to slide along the inner wall of the connecting groove 1201, and then the slide plate 1204 drives the locking block 6 to slide along the inner wall of the second sliding groove 11 through the transition plate 1203.

[0032] like Figure 2-6As shown, the thrust assembly 5 includes a threaded shaft 501, a placement groove 502, a spring 503, and a handle 504; the threaded shaft 501 is threadedly connected to the slide plate 1204, one end of the threaded shaft 501 is fixedly connected to the handle 504, and the other end of the threaded shaft 501 is rotatably connected to the inner wall of the connecting groove 1201 near the lower clamp 1; a plurality of evenly distributed placement grooves 502 are opened at one end of the slide plate 1204 near the lower clamp 1, and a spring 503 is provided in the placement groove 502, and the other end of the spring 503 is fixedly connected to the inner wall of the connecting groove 1201 near the lower clamp 1.

[0033] Understandably, the spring 503 always applies an elastic force toward the lower clamp 1 to the slide plate 1204, making it easier to rotate the throttle 504 and reducing the force between the threaded shaft 501 and the slide plate 1204, thereby effectively alleviating thread wear between the threaded shaft 501 and the slide plate 1204 and extending their service life.

[0034] Specifically, rotating the throttle 504 drives the threaded shaft 501 to rotate, and then the threaded shaft 501 drives the slide plate 1204 to slide along the inner wall of the connecting groove 1201.

[0035] Specifically, the thrust assembly 5 drives the slide plate 1204 to slide along the inner wall of the connecting groove 1201. Then, the slide plate 1204 drives the locking block 6 to slide along the inner wall of the second sliding groove 11 via the transition plate 1203. Then, the end of the locking block 6 with the chamfer 4 reaches the position of the locking groove 13. As the locking block 6 continues to slide, the end of the locking block 6 with the chamfer 4 is engaged in the inner wall of the locking groove 13. While sliding along the inner wall of the locking groove 13, it drives the locking block 10 to descend. Then, the locking block 10 drives the abutment plate 14 to descend and press the upper connecting block 8 and the lower connecting block 7. Until the chamfer 4 disengages from the inner wall of the slot 13, the lower connecting block 7 and the upper connecting block 8 are securely fixed, which can effectively control the tightening force of the abutment plate 14 on both sides of the lower connecting block 7 and the upper connecting block 8 to be the same, making operation simple; the spring 503 always applies an elastic force towards the lower clamp 1 to the slide plate 1204, making it easier to rotate the handle 504 and reduce the force between the threaded shaft 501 and the slide plate 1204, thereby effectively alleviating the thread wear between the threaded shaft 501 and the slide plate 1204, and thus extending the service life.

[0036] The working principle of this utility model is as follows: the upper hoop 2 and the sealing ring 3 are wrapped around the pipe to be connected. Then the locking block 10 is inserted into the first sliding groove 9. Then the handle 504 is rotated. The handle 504 drives the threaded shaft 501 to rotate. Then the threaded shaft 501 drives the slide plate 1204 to slide along the inner wall of the connecting groove 1201. The spring 503 simultaneously applies an elastic force towards the lower hoop 1 to the slide plate 1204. The front end of the locking block 6 first abuts against the inner wall of the locking groove 13. Then the locking block 6 continues to slide along the inner wall of the second sliding groove 11 while driving the locking block 10 to descend. Then the locking block 10 drives the abutment plate 14 to descend, thereby pressing the lower connecting block 7 and the upper connecting block 8.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
