Description

Technical Field

[0001] The present invention relates to the field of pipe connections, and more particularly to a water pipe connection structure. Background Art

[0002] The existing water pipe joint connection structures generally use clamp fixing connections or threaded connections to achieve sealed fixed connections. Both of these methods require the assistance of tools to complete disassembly and assembly during installation, which is relatively troublesome, time-consuming and laborious. Based on this, this application is designed. Summary of the Invention

[0003] The problem solved by the present invention is that the disassembly and assembly of the existing water pipe joint connection structure requires the assistance of tools and is not convenient enough.

[0004] To solve the above problems, the present invention provides a water pipe connection structure for connecting a first pipe joint and a second pipe joint. The water pipe connection structure includes an arc-shaped piece, and the arc-shaped piece can be clamped at the connection of the first pipe joint and the second pipe joint by its own elastic deformation.

[0005] The arc-shaped piece is provided with a clamping hole extending along the arc length direction. The first pipe joint and the second pipe joint are provided with clamping blocks. When the arc-shaped piece is clamped at the connection of the first pipe joint and the second pipe joint, the clamping blocks of the first pipe joint and the second pipe joint extend into the clamping hole and are inseparably close together to prevent the first pipe joint and the second pipe joint from separating.

[0006] The end of the first pipe joint is provided with an inner pipe, and a sealing ring is tightly sleeved outside the inner pipe. The sealing ring extends into the second pipe joint together with the inner pipe to make the first pipe joint and the second pipe joint be sealed and connected.

[0007] When the water pipe connection structure of the embodiment of the present invention is in use, first insert the inner pipe into the second pipe joint to make the first pipe joint and the second pipe joint be sealed and connected, then clamp the arc-shaped piece at the connection of the first pipe joint and the second pipe joint, and make the clamping blocks of the first pipe joint and the second pipe joint extend into the clamping hole. Since the clamping blocks of the first pipe joint and the second pipe joint are tightly close together and inseparable in the clamping hole, that is, it is equivalent to the fixed connection of the first pipe joint and the second pipe joint and inseparable, thereby realizing the sealed fixed connection of the first pipe joint and the second pipe joint. The whole disassembly and assembly process does not require the assistance of any tools and is very convenient.

[0008] Further, the arc corresponding to the arc-shaped piece is a major arc.

[0009] In this technical solution, the larger the radian of the arc corresponding to the arc-shaped piece, the more reliable the sealed fixed connection of the arc-shaped piece to the first pipe joint and the second pipe joint.

[0010] Further, the clamping hole is a through hole.

[0011] In this technical solution, the through hole design facilitates the blocking member to pass through the blocking hole to firmly connect the pipe joint 1 and the pipe joint 2 together.

[0012] Furthermore, a connecting piece 1 is provided in the middle of the arc-shaped piece, and the connecting piece 1 spans across the clamping hole and is fixedly connected to the arc-shaped pieces on both sides of the clamping hole;

[0013] The distance from the connecting piece 1 to the center of the circle corresponding to the arc-shaped piece is greater than the distance from the arc-shaped piece to the center of the circle.

[0014] In this technical solution, the design of the connecting piece 1 prevents the width of the clamping hole here from becoming larger and affecting the firm connection strength of the pipe joint 1 and the pipe joint 2.

[0015] Furthermore, the length of the clamping hole in the axial direction of the cylinder corresponding to the arc-shaped piece is equal to the sum of the lengths of the two clamping parts in the axial direction of the pipe joint.

[0016] In this technical solution, the two blocking members are designed so that they can be tightly attached together and cannot be separated after they are inserted into the blocking holes.

[0017] Furthermore, the blocking member is a circular ring, and the two circular rings are tightly sleeved on the pipe joint 1 and the pipe joint 2 respectively.

[0018] In this technical solution, the use of a circular ring as the blocking member can maximize the contact area between the blocking member and the blocking hole, which helps to ensure uniform force on all parts of the arc-shaped piece.

[0019] Furthermore, there are two arc-shaped pieces, the arc corresponding to each arc-shaped piece is a minor arc, the two arc-shaped pieces are fixedly connected by a second connecting piece, and the distance from the second connecting piece to the center of the circle corresponding to the arc-shaped piece is greater than the distance from the arc-shaped piece to the center of the circle.

[0020] In this technical solution, the presence of the second connecting piece enhances the mechanical strength of the water pipe connection structure, preventing the blocking member from pushing the clamping hole, causing the width of the clamping hole to increase and affecting the firm connection strength of the pipe joints one and two.

[0021] Furthermore, the second connecting piece is provided with a slot for the blocking member to be inserted into.

[0022] In this technical solution, if the blocking member passes through the blocking hole, a blocking groove must be provided on the second connecting piece to ensure the normal use of the water pipe connection structure.

[0023] Furthermore, the second connecting piece is U-shaped.

[0024] In this technical solution, the U-shaped connecting piece facilitates the processing of the slot.

[0025] Furthermore, the end of the arc-shaped piece extends in a direction away from the circle corresponding to the arc-shaped piece to form a paddle.

[0026] In this technical solution, the presence of the paddle makes it easy to open and clamp the arc-shaped piece into the connection between the pipe joint 1 and the pipe joint 2.

[0027] Beneficial effect: When the water pipe connection structure of the present application is used, the inner tube is first inserted into the pipe joint 2 to make the pipe joint 1 and the pipe joint 2 sealed and connected, and then the arc piece is clamped at the connection between the pipe joint 1 and the pipe joint 2, and the blocking parts of the pipe joint 1 and the pipe joint 2 are extended into the clamping hole. Since the blocking parts of the pipe joint 1 and the pipe joint 2 are tightly together and inseparable in the clamping hole, it is equivalent to the fixed connection between the pipe joint 1 and the pipe joint 2, which is inseparable, thereby realizing the sealed and fixed connection between the pipe joint 1 and the pipe joint 2. The entire disassembly and assembly process only requires the arc piece to be opened and clamped into the connection between the pipe joint 1 and the pipe joint 2 or the pipe joint 1 and the pipe joint 2 to be removed from the opened arc piece, without the aid of any tools, which is very convenient.

[0040] The present invention provides a water pipe connection structure, which is used to connect a pipe joint 1 and a pipe joint 2.

[0041] Embodiment 1:

[0042] Reference Figure 1 and Figure 3 As shown, the water pipe connection structure includes a clamp spring 7, and the clamp spring 7 includes an arc-shaped piece 71. The arc-shaped piece 71 can be clamped at the connection between the pipe joint 1 and the pipe joint 2 by means of its own elastic deformation. When in use, the arc-shaped piece 71 can be broken apart to be clamped at the connection between the pipe joint 1 and the pipe joint 2;

[0043] like Figure 1 and Figure 4As shown, the arc-shaped sheet 71 is provided with a clamping hole 8 extending in the arc length direction. Preferably, the clamping hole 8 is a through hole. The pipe joint 1 and the pipe joint 2 are provided with a clamping member. Preferably, the clamping member is a circular ring, which is tightly sleeved on the pipe joint 1 and the pipe joint 2. The length of the clamping hole 8 in the axial direction of the cylinder corresponding to the arc-shaped sheet 71 is equal to the sum of the lengths of the two clamping members in the axial direction of the pipe joint, that is, Figure 1 The thickness of the middle ring is half of the width of the clamping hole 8. With this design, the two clamping members can only be closely attached to each other and cannot be separated after they are inserted into the clamping hole 8. During installation, when the arc-shaped sheet 71 is clamped at the connection between the pipe joint 1 and the pipe joint 2, the clamping members of the pipe joint 1 and the pipe joint 2 are inserted into the clamping hole 8 and cannot be separated and tightly attached to each other, so as to prevent the pipe joint 1 and the pipe joint 2 from being separated, thereby realizing the fixed connection between the pipe joint 1 and the pipe joint 2;

[0044] In this embodiment, if Figure 2 As shown, an inner tube 5 is provided at the end of the pipe joint 1, and a sealing ring 6 is tightly sleeved on the outer side of the inner tube 5. The sealing ring 6 extends into the pipe joint 2 together with the inner tube 5 to make the pipe joint 1 and the pipe joint 2 2 sealed and connected.

[0045] When the water pipe connection structure of the embodiment of the present invention is used, the inner tube 5 is first inserted into the pipe joint 2 to make the pipe joint 1 and the pipe joint 22 sealed and connected, and then the arc piece 71 is clamped at the connection between the pipe joint 1 and the pipe joint 2, and the blocking parts of the pipe joint 1 and the pipe joint 2 are extended into the clamping hole 8. Since the blocking parts of the pipe joint 1 and the pipe joint 2 are tightly attached to each other in the clamping hole 8 and cannot be separated, it is equivalent to the fixed connection between the pipe joint 1 and the pipe joint 2, which is inseparable, thereby realizing the sealed and fixed connection between the pipe joint 1 and the pipe joint 2. The entire disassembly and assembly process only requires opening the arc piece 71, and no tools are required, which is very convenient.

[0046] In this embodiment, if Figures 1 - 4As shown, there are two arc-shaped pieces 71, and the arc corresponding to each arc-shaped piece 71 is a minor arc. The two arc-shaped pieces 71 are fixedly connected by a second connecting piece 73. The distance from the second connecting piece 73 to the center of the circle corresponding to the arc-shaped piece 71 is greater than the distance from the arc-shaped piece 71 to the center of the circle. In this way, the second connecting piece 73 will not block the blocking piece from passing through the blocking hole 8. In addition, the existence of the second connecting piece 73 enhances the mechanical strength of the water pipe connection structure, and avoids the blocking piece from pushing the blocking hole 8 to cause the width of the blocking hole 8 to increase and the arc The deformation of the sheet 71 affects the firm connection strength of the pipe joint 1 and the pipe joint 2. Furthermore, the connecting sheet 2 73 is provided with a slot 75 for the blocking piece to be inserted into. If the blocking piece passes through the hole 8, the slot 75 must be provided on the connecting sheet 2 73 to ensure that the connecting sheet 2 73 does not block the blocking piece from passing through the hole 8, thereby ensuring the normal use of the water pipe connection structure. Furthermore, the connecting sheet 2 73 is U-shaped, and the U-shaped structure of the connecting sheet 2 73 facilitates the processing of the slot 75.

[0047] In this embodiment, if Figures 1 - 4 As shown, the end of the arc piece 71 away from the connecting piece 2 73 extends in a direction away from the center of the circle corresponding to the arc piece 71 to form a paddle 72. The existence of the paddle 72 makes it convenient for fingers to open and clamp the arc piece 71 into the connection between the pipe joint 1 and the pipe joint 2.

[0048] Embodiment 2:

[0049] The difference between this embodiment and the first embodiment is that the arc corresponding to the arc-shaped piece 71 is a major arc. Figure 5 and Figure 6 As shown, the paddle 72 is provided at both ends of the arc-shaped piece 71. The water pipe connection structure of this structure is simpler in structural design and has lower manufacturing cost.

[0050] In this embodiment, further, a connecting piece 74 is provided in the middle of the arc piece 71, and the connecting piece 74 spans the card hole 8 and is fixedly connected to the arc pieces 71 on both sides of the card hole 8. Such a design can prevent the blocking member from expanding the width of the card hole 8 and affecting the firm connection strength of the pipe joint 1 and the pipe joint 2. Therefore, the structural strength of the middle part of the arc piece 71 is the lowest, and the structural strength of the two ends of the arc piece 71 is the highest. Therefore, in order to prevent the blocking members of the pipe joint 1 and the pipe joint 2 from expanding the width of the card hole 8, a connecting piece 74 is specially provided in the middle part of the arc piece 71. In addition, the distance from the connecting piece 74 to the center of the circle corresponding to the arc piece 71 is greater than the distance from the arc piece 71 to the center of the circle. With such a design, the connecting piece 74 does not affect the blocking member passing through the card hole 8.

[0051] When the water pipe connection structure of this embodiment is used, the inner tube 5 is first inserted into the pipe joint 2 to make the pipe joint 1 and the pipe joint 22 sealed and connected, and then the arc piece 71 is clamped at the connection between the pipe joint 1 and the pipe joint 2, and the blocking parts of the pipe joint 1 and the pipe joint 2 are extended into the clamping hole 8. Since the blocking parts of the pipe joint 1 and the pipe joint 2 are tightly together and inseparable in the clamping hole 8, it is equivalent to the fixed connection between the pipe joint 1 and the pipe joint 2, and cannot be separated, thereby realizing the sealed and fixed connection between the pipe joint 1 and the pipe joint 2. The entire disassembly and assembly process only requires the arc piece 71 to be opened and clamped into the connection between the pipe joint 1 and the pipe joint 2, or the pipe joint 1 and the pipe joint 2 are taken out from the opened arc piece 71, without the aid of any tools, which is very convenient.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
