[0003] In the prior art, PE pipes are usually connected by hot melt connection. When performing hot melt connection, it is necessary to use a positioning tool to position the PE pipe, and then perform operations such as grinding and cutting the edges of the pipe connection. Finally, after using hot melt equipment to hot-melt the connection ports of the two PE pipes to be connected, the two PE pipes are quickly docked, so that the two PE pipes are installed and connected, and the PE pipes have better sealing after connection. However, when using hot melt connection, due to the positioning, grinding, cutting and hot melting of the pipes, it takes a lot of time, which makes the pipe connection efficiency low. At the same time, the above operations usually require a large number of operators to perform together, so it is more labor-intensive.

[0004] Therefore, there is an urgent need for a PE pipe quick installation clamp to make the connection speed of PE pipe faster. Utility Model Content

[0052] Example 1

[0053] It should be understood that when using a hot melt connection method to connect two PE pipes 100 (hereinafter referred to as pipes 100), due to the positioning, grinding, cutting and hot melting of the pipes 100, it takes a lot of time, which makes the connection efficiency of the pipes 100 low. At the same time, the above operations usually require more operators to perform together, so it is more manpower-consuming.

[0054] Therefore, in order to improve the above problems, this embodiment provides a pipeline quick installation fixture, such as Figure 1and Figure 2 As shown, it mainly comprises an upper half casing 200, a lower half casing 300 and a plurality of clamping members 400. This structure allows the connection speed of two pipes 100 to be faster.

[0055] The upper half sleeve 200 and the lower half sleeve 300 are connected by a plurality of clamping members 400. Specifically, Figure 1 and Figure 2 As shown, the upper sleeve 200 and the lower sleeve 300 can both adopt a semi-circular structure. When the upper sleeve 200 and the lower sleeve 300 are clamped together, the upper sleeve 200 and the lower sleeve 300 form a cylinder with a through hole, and the pipe 100 can be inserted from both ends of the cylinder.

[0056] Among them, Figures 1-6 As shown, upper connecting bosses 210 are provided on both sides of the upper half sleeve 200. Specifically, the upper connecting bosses 210 adopt a rectangular structure.

[0058] The two lower connecting bosses 310 are both provided with a plurality of clamping members 400 of the same number, and the clamping members 400 are rotatably connected to the connecting bosses, so that the clamping members 400 rotate to the upper connecting boss 210, thereby clamping the upper half sleeve 200 and the lower half sleeve 300.

[0059] Among them, the end faces of both ends of the upper sleeve 200 extend along the radial direction of the upper sleeve 200 to adapt to the pipe 100, and the end faces of both ends of the lower sleeve 300 extend along the radial direction of the upper sleeve 200 to adapt to the pipe 100, so that when the upper sleeve 200 and the lower sleeve 300 clamp the pipe 100 between the upper sleeve 200 and the lower sleeve 300, the ends of the upper sleeve 200 and the lower sleeve 300 abut against the pipe 100, thereby fixing the two pipes 100, and thus making the connection of the two pipes 100 stable.

[0060] In this embodiment, the upper connecting platform and the lower connecting platform are both provided with a plurality of snap-fit grooves 500. The snap-fit groove 500 provided on the upper connecting boss 210 has a notch facing away from the upper connecting boss 210, and the snap-fit groove 500 provided on the lower connecting boss 310 has a notch facing away from the lower connecting boss 310. Specifically, the plurality of snap-fit grooves 500 of the upper connecting boss 210 and the lower connecting boss 310 connected to each other are respectively provided in a one-to-one correspondence.

[0061] Among them, Figure 11-14 As shown, the clamping member 400 also includes an upper side plate 410, a lower side plate 420, a driving plate 430, a guide rod 440, a connecting rod 450 and a compression spring 460, wherein the driving plate 430, the upper side plate 410 and the lower side plate 420 can all be cylindrical or rectangular in shape. In this embodiment, the driving plate 430, the upper side plate 410 and the lower side plate 420 are all rectangular, and the areas of the driving plate 430, the upper side plate 410 and the lower side plate 420 are the same.

[0062] Among them, Figures 1-14 As shown, when the clamping member 400 clamps the upper plate sleeve and the lower half sleeve 300, the upper half sleeve 200 is located directly above the lower half sleeve 300, and the upper plate sleeve and the lower half sleeve 300 are both placed horizontally on the horizontal ground, the driving plate 430, the upper side plate 410 and the lower side plate 420 are sequentially spaced along the direction of gravity, wherein the connecting rod 450 vertically passes through the lower side plate 420, and the lower side plate 420 can slide up and down relative to the connecting rod 450, and one end of the connecting rod 450 is in contact with the lower surface of the upper side plate 410. The other end of the connecting rod 450 is rotatably connected to the clamping groove 500, the guide rod 440 is passed through the upper side plate 410, and the guide rod 440 can slide up and down relative to the upper side plate 410, and the two ends of the guide rod 440 are respectively connected to the lower surface of the driving plate 430 and the upper surface of the lower side plate 420, and the compression spring 460 is arranged between the upper side plate 410 and the lower side plate 420, and the two ends of the compression spring 460 are respectively connected to the lower surface of the upper side plate 410 and the upper surface of the lower side plate 420.

[0063] When the guide rod 440 slides up and down relative to the upper plate 410, since the lower plate 420 can slide up and down relative to the connecting rod 450 and the guide rod 440 is connected to the lower plate 420, the guide rod 440 can drive the lower plate 420 to move up and down.

[0064] In this embodiment, Figure 11-14 As shown, a rotating shaft 470 is provided at one end of the connecting rod 450 facing away from the driving plate 430, wherein the rotating shaft 470 is passed through the bottom end of the connecting rod 450, and the two ends of the rotating shaft 470 are rotatably connected to the two side inner walls of the clamping groove 500, so that the connecting rod 450 can rotate relative to the lower connecting boss 310 and the upper connecting boss 210.

[0065] In this embodiment, there are multiple compression springs 460, and the multiple compression springs 460 are arranged in sequence and at intervals between the upper side plate 410 and the lower side plate 420, and the multiple compression springs 460 are evenly arranged on both sides of the connecting rod 450. There are multiple guide rods 440, and the multiple guide rods 440 pass through the upper side plate 410, and the two ends are respectively connected to the driving plate 430 and the lower side plate 420, and the multiple guide rods 440 are evenly arranged on both sides of the connecting rod 450, wherein the multiple compression springs 460 and the guide rods 440 arranged on the same side of the connecting rod 450 are arranged in sequence and at intervals, and the multiple compression springs 460 are arranged between the multiple guide rods 440 and the connecting rod 450, wherein the multiple guide rods 440 are symmetrically arranged on both sides of the connecting rod 450, and the multiple compression springs 460 are symmetrically arranged on both sides of the connecting rod 450.

[0066] A pull ring 480 is provided on the upper surface of the driving plate 430 , thereby making it easier to pull the driving plate 430 .

[0067] In this embodiment, when the upper half sleeve 200 and the lower half sleeve 300 are connected by using the clamping member 400, the driving plate 430 is first pulled by pulling the pull ring 480 on the driving plate 430, so that the driving plate 430 is displaced relative to the upper side plate 410 along the axial direction of the connecting rod 450 away from the rotating shaft 470. At the same time, the driving plate 430 drives the lower side plate 420 to slide relative to the connecting rod 450 along the axial direction of the connecting rod 450 through the guide rod 440. At this time, the compression spring 460 is squeezed by the upper side plate 410 and the lower side plate 420 and is in a compressed state. Finally, the connecting rod 450 is rotated relative to the clamping groove 500, so that the clamping member 400 rotates as a whole, thereby causing the upper side plate 410, the lower side plate 420 and the driving plate 430 to rotate. Rotate to the top of the upper connecting boss 210. At this time, loosen the pull ring 480 and the compression spring 460 extends, thereby squeezing the lower side plate 420 to abut against the upper surface of the upper connecting boss 210. At this time, the compression spring 460 is still in a compressed state, thereby continuously applying force to the lower side plate 420, thereby making the connection between the upper connecting boss 210 and the lower connecting boss 310 stable. When clamping, the upper half sleeve 200 and the lower half sleeve 300 can be stably connected by pulling the pull ring 480 and rotating the clamping part 400. The operation steps are few and the operation is simple, so that the connection speed of the upper half sleeve 200 and the lower half sleeve 300 is faster, and the connection speed between the two pipes 100 is faster.

[0068] In this embodiment, when it is necessary to install and connect two pipes 100, first, the two pipes 100 need to be placed on the lower half sleeve 300 from both ends thereof, so that the end faces of the two ends of the lower half sleeve 300 abut against the outer wall of the pipe 100. After the end faces of the two pipes 100 abut against each other, the upper half sleeve 200 is covered on the pipe 100 and the lower half sleeve 300, and the two end faces of the upper half sleeve 200 facing downwards abut against the two end faces of the lower half sleeve 300 facing upwards, and the upper half sleeve 200 is The left and right end faces of 0 are against the outer wall of the pipe 100, wherein the upper connecting bosses 210 on both sides of the upper half sleeve 200 and the lower connecting boss 310 of the lower half sleeve 300 are aligned, and the lower surface of the upper connecting boss 210 and the upper surface of the lower half sleeve 300 are in contact. Finally, the upper connecting boss 210 and the lower connecting boss 310 are connected by multiple clamping parts 400, so that the connection between the upper half sleeve 200 and the lower half sleeve 300 is stable and the connection speed is fast, thereby making the connection speed of the two pipes 100 faster.

[0069] Furthermore, due to the irreversible nature of the hot melt connection, if quality problems such as misalignment occur during the connection of the pipe 100 and the pipe 100 needs to be replaced or reconnected, the pipe 100 needs to be cut at the connection before it can be reconnected, making it difficult to reconnect the pipe 100 after it is connected. In this embodiment, since the upper half sleeve 200 and the lower half sleeve 300 are detachably connected by snap-fitting, the two pipes 100 can be disassembled and reconnected by disassembly.

[0070] Example 2

[0071] According to the clamp described in the above embodiment, in order to make the connection between the upper half sleeve 200 and the lower half sleeve 300 more stable, thereby making the connection between the two pipes 100 more stable, in this embodiment, as shown in FIG Figure 11-14 As shown, the lower side plate 420 is provided with a plurality of fixing rods 490 , which are evenly and symmetrically arranged on both sides of the connecting rod 450 , and the fixing rods 490 arranged on the same side of the connecting rod 450 are arranged in sequence and spaced apart.

[0072] like Figures 1-6 As shown, a plurality of fixing holes 230 are symmetrically and evenly provided on both sides of the clamping groove 500 provided on the upper connecting boss 210 , wherein the plurality of fixing holes 230 are arranged along the vertical direction.

[0073] In this embodiment, when the upper half sleeve 200 and the lower half sleeve 300 are connected, multiple fixing rods 490 are respectively inserted into the multiple fixing holes 230, so that the position of the clamping member 400 is stable, and the clamping of the upper half sleeve 200 and the lower half sleeve 300 is stabilized. In addition, the fixing rod 490 also has a positioning function, so that the clamping member 400 can be rotated to a fixed position for clamping.

[0074] Example 3

[0075] It should be understood that when two pipes 100 need to be connected, the end faces of the two pipes 100 need to be aligned before connecting the two pipes 100, so as to avoid a gap in the connection between the two pipes 100, which may cause water leakage.

[0076] Therefore, in order to connect and align the two pipes 100, according to the clamp described in the above embodiment, in this embodiment, please refer to FIG. Figure 1-Figure 2 As shown, the end surfaces at both ends of the upper sleeve 200 extend along the axial direction of the upper sleeve 200 to form an upper fixed sleeve 220, and the end surfaces at both ends of the lower sleeve 300 extend along the axial direction of the lower sleeve 300 to form a lower fixed sleeve 320, and upper connecting bosses 210 and lower connecting bosses 310 are provided on both sides of the upper fixed sleeve 220 and the lower fixed sleeve 320, wherein the upper connecting boss 210 provided on the upper fixed sleeve 220 and the lower connecting boss 310 provided on the lower fixed sleeve 320 also adopt the same clamping structure as the upper sleeve 200 and the lower sleeve 300.

[0077] In this embodiment, when the upper fixed sleeve 220 and the lower fixed sleeve 320 are clamped, the inner walls of the upper fixed sleeve 220 and the lower fixed sleeve 320 are both against the outer wall of the pipe 100, so that the contact area between the upper fixed sleeve 220 and the lower fixed sleeve 320 and the pipe 100 is larger, thereby more stably supporting the pipe 100, so that the position of the pipe 100 is stable when connected, and the two pipes 100 can be more accurately aligned when connected.

[0078] Among them, Figure 2 As shown, a sealing gasket 900 is provided between the upper fixed sleeve 220 and the lower fixed inner wall sleeve and the outer wall of the pipe 100. The sealing gasket 900 is made of rubber material, so that the connection between the upper fixed pipe and the lower fixed pipe and the pipe 100 is tight, thereby preventing water leakage.

[0079] In this embodiment, in order to further stabilize the positions of the two pipes 100 and thus make the alignment of the two pipes 100 more accurate, as shown in FIG. Figure 2 and 7As shown, the pipeline quick installation fixture also includes a sealing sleeve 600, wherein the sealing sleeve 600 adopts a cylindrical structure, and the sealing sleeve 600 is adapted to the cylinder formed after the upper sleeve 200 and the lower sleeve 300 are clamped together. Specifically, when the upper sleeve 200 and the lower sleeve 300 are clamped together, the end faces at both ends are against the outer wall of the pipeline 100, and the middle tube bodies are clamped together to form a cylindrical cavity, and the sealing sleeve 600 is arranged in the cavity.

[0080] The end surfaces of both ends of the sealing sleeve 600 extend along the radial direction of the sealing sleeve 600 until they abut against the outer wall of the pipe 100 , thereby stabilizing the position of the pipe 100 and facilitating the alignment of the two pipes 100 .

[0081] At the same time, in order to make the distances between the two pipes 100 inserted into the sealing sleeve 600 consistent, and thus make the two pipes 100 receive the same force, in this embodiment, Figure 2 、 Figure 7 、 Figure 9 and 15 As shown, the clamp also includes two limit rods 700, and two limit sleeves 610 are provided at the center of the inner wall of the sealing sleeve 600. The two limit sleeves 610 are symmetrically arranged, and the two limit rods 700 are respectively inserted into the two limit sleeves 610, and the end face of one end of the limit rod 700 inserted into the limit sleeve 610 is connected to the end face of the limit sleeve 610 through a limit spring 800. When the pipe 100 is inserted into the sealing sleeve 600, the end face of the pipe 100 is against the limit rod 700, thereby making the insertion distance of the pipe 100 controllable.

[0082] A limiting boss 611 is provided in the limiting sleeve 610, and a limiting end 710 is provided at one end of the limiting rod 700. The limiting end 710 is arranged between the inner wall of the sealing sleeve 600 and the limiting boss 611, and the outer wall of the limiting end 710 is in contact with the inner wall of the limiting sleeve 610. A semicircular ring 720 is provided at the end of the limiting rod 700 away from the limiting sleeve 610, and the limiting rod 700 is arranged at the center of the semicircular ring 720. Specifically, the two semicircular rings 720 are both semicircular structures. When the end faces of the two semicircular rings 720 facing the same direction are against each other, the two semicircular rings 720 form a cylinder, and the cylinder is adapted to the pipe 100. At the same time, the inner wall of the pipe 100 close to the end face is in contact with the outer wall of the cylinder formed by the two semicircular rings 720.

[0083] The end face of the semicircular collar 720 is bent toward the limiting rod 700, so that the end face of the semicircular collar 720 has an arc surface. When the pipe 100 is inserted into the sealing sleeve 600, the end face of the pipe 100 contacts the arc surface of the semicircular collar 720 and squeezes the arc surface, so that the semicircular sleeve is displaced in a direction away from the corresponding limiting sleeve 610, thereby pulling the limiting spring 800, so that the limiting spring 800 is in a stretched state. When the end face of the pipe 100 is displaced along the arc surface of the semicircular collar 720 to the outer wall of the semicircular collar 720, and continues to displace to the position aligned with the limiting rod 700, the semicircular collar 720 is in a stretched state. When the sides are fitted together, since the limit spring 800 is always in a stretched state, the limit spring 800 applies a pulling force to the semicircular ring 720 through the limit rod 700, so that the outer wall of the semicircular ring 720 fits tightly with the inner wall of the pipe 100, thereby making the seal between the two pipes 100 better and not prone to water leakage. Moreover, due to the limit boss 611, even if the semicircular ring 720 is impacted by water pressure, the semicircular ring 720 will not produce a large gap with the pipe 100 under the action of the limit boss 611, further making the sealing effect of the two pipes 100 better after being connected.

[0084] It should be understood that even if the end faces of both ends of the pipe 100 are adapted to the sealing sleeve 600, due to manufacturing precision issues and in order to allow the pipe 100 to be inserted into the sealing sleeve 600, there may still be small gaps between the inner walls of the end faces of the sealing sleeve 600 and the pipe 100, and between the semicircular sleeve and the inner wall of the pipe 100, which may cause water leakage.

[0085] Therefore, in order to solve the above problems, in this embodiment, two sealing rings 620 are provided in the sealing sleeve 600, and the two sealing rings 620 are evenly arranged on both sides of the limiting rod 700. When the pipe 100 is inserted into the sealing sleeve 600, the end faces of the two sealing rings 620 are in contact with the outer wall of the pipe 100, thereby further improving the sealing effect between the clamp and the pipe 100. At the same time, the sealing ring 620 can also support the pipe 100, so that the position of the two pipes 100 is stable when connected.

[0086] A plurality of rubber ring gaskets 630 are provided between the end face of the sealing sleeve 600 and the sealing ring 620 on the same side of the limiting rod 700. The plurality of rubber ring gaskets 630 are arranged in sequence at intervals. When the pipe 100 is inserted into the sealing sleeve 600, one end of the rubber ring gasket 630 bends and abuts against the outer wall of the pipe 100. Specifically, the rubber ring gasket 630 is made of rubber or other materials, and the diameter of the circle formed by the inner wall of the rubber sealing ring 620 is smaller than the diameter of the outer wall of the pipe 100. Therefore, when the pipe 100 is inserted into the sealing sleeve 600, the pipe 100 squeezes the sealing ring 620 gasket, causing the sealing ring 620 gasket to bend, and the bent end is in close contact with the outer wall of the pipe 100, thereby achieving a better sealing effect between the clamp and the pipe 100.

[0087] The side of the rubber ring gasket 630 facing away from the limiting rod 700 is an inclined surface, so that the contact area between the rubber ring gasket 630 and the outer wall of the pipe 100 is larger, thereby achieving a better sealing effect.
