Description

Technical Field

[0001] The present invention relates to the technical field of fixtures, and specifically provides a rotatable pipe fixture. Background Art

[0002] When bonding UPVC pipes, the pipe ends should be cut flat and perpendicular to the pipe axis. Generally, a pipe fixing box and a handsaw or pipe cutter can be used for operation. After cutting, clean the inside and outside of the pipe from debris and chamfer (10 - 15 degrees), wipe off the dust, oil stains and moisture inside and outside the pipe (moisture, dust and oil stains will affect the bonding strength), measure the insertion depth of the fitting with a measuring tool, and mark the measured size on the socket of the pipe. When starting the bonding, first apply the pre-bonding glue forcefully on the inner wall of the socket of the fitting. This operation strictly prohibits the pre-bonding glue from flowing into the inside of the fitting. Then apply the pre-bonding glue forcefully on the marked range of the socket of the pipe, and apply the glue evenly on the socket of the pipe. The length of the glue application is the marked range. Immediately, use the brush of the pipe with the applied glue to apply glue on the inner wall of the socket of the fitting. When the glue is still wet, immediately insert the pipe into the fitting and push the pipe to the bottom of the fitting with sufficient force. And rotate the pipe and the fitting relative to the circumference by 15° - 45°. After connecting the pipe interface tightly, keep it static until the fitting will not be pushed out. When the interface pipe work is completed, there should be a circle of glue at the interface. Wipe off the excess glue at the interface with a cloth.

[0003] According to the above pipe bonding process, two actions of inserting and bonding the pipes to be bonded and related circumferential rotation are required. However, when the pipe diameter is large, it will be time-consuming and laborious to complete the insertion and bonding work manually. In this case, the bonding quality of the pipe will be greatly affected.

[0004] Therefore, according to the above bonding requirements, the inventor of the present invention has studied a pipe fixture that can assist workers in completing two functions of pipe insertion and rotation simultaneously. Summary of the Invention

[0005] The present invention provides a rotatable pipe fixture, aiming to solve the technical problems of inserting and bonding and related circumferential rotation of large-diameter plastic pipes during bonding.

[0006] The technical solution of the present invention is as follows:

[0007] A rotatable pipe fixture, characterized by comprising a thrust rod 1, a rotating clamping ring 2, and a fixed clamping ring 3;

[0008] The thrust rod 1 includes a main rod 11 and a sub-rod 12 hinged to the lower part of the main rod. Transverse connecting rods one 111 and two 121 are respectively arranged at the heads of the main rod and the sub-rod;

[0009] The described rotating clamping ring 2 includes an upper rotating clamping ring 21 and a lower rotating clamping ring 22, which are two semi - rings that are buckled together, and a handle 23, a clamping groove 24, and a fixing bolt 25 provided on the ring. When the two semi - rings are buckled together, one side is connected together by the fixing bolt 25, and the other side is connected by a pin hinge connection;

[0010] The described fixed clamping ring 3 includes an upper fixed clamping ring 31 and a lower fixed clamping ring 32, which are two semi - rings that are buckled together, a pulling groove 33, a shaft 34, and a first fixing bolt 35; when the two semi - rings are buckled together, one side is connected together by the first fixing bolt 35, and the other side is connected by a shaft 34 hinge connection;

[0011] The fixed clamping ring 3 is clamped on the outer wall of the interface on the first pipe body, and the rotating clamping ring 2 is clamped on the outer wall of the interface on the second pipe body to be bonded. The pulling groove 33 and the clamping groove 24 open in opposite directions. The transverse connecting rod 111 of the main rod 11 of the thrust rod 1 is stuck in the pulling groove 33 of the fixed clamping ring 3, and the transverse connecting rod 121 of the secondary rod 12 is stuck in the clamping groove 24 of the rotating clamping ring 2. Pushing the thrust rod 1 between the fixed clamping ring 3 and the rotating clamping ring 2 causes the connected pipes to be inserted into each other.

[0012] In the described rotatable pipe clamp, the clamping groove 24 and the pulling groove 33 are correspondingly arranged.

[0013] In the described rotatable pipe clamp, two thrust rods 1 are symmetrically arranged.

[0014] In the operation method of the described rotatable pipe clamp, first, open the fixed clamping ring 3 and position it. After positioning, fix the fixed clamping ring 3 on the first pipe body through the first fixing bolt 35. Use the same method to fix the rotating clamping ring 2 on the second pipe body to be bonded. After the fixture is fixed, the transverse connecting rod 111 at the front end of the main rod 11 of the thrust rod 1 is stuck in the pulling groove of the fixed clamping ring 3, and then the transverse connecting rod 121 at the front end of the secondary rod 12 of the thrust rod is stuck in the clamping groove of the rotating clamping ring 2. When the upper and lower two thrust rods are fixed, manually clamp the thrust rods towards the middle. At this time, the second pipe body will complete the insertion action towards the first pipe body side. After the insertion action is completed, remove the upper and lower two thrust rods, and then hold the handle 23 of the rotating clamping ring 2 to complete the rotation action of the second pipe body.

[0015] The beneficial effects of the present invention:

[0016] The fixture of the present invention can assist manual labor to complete the two actions of inserting and rotating the pipes to be bonded, so as to save manpower, improve efficiency, and ensure the bonding effect. Description of the Drawings

[0025] Refer to Figures 6 - 9 shown, which is the single-piece and assembled schematic diagrams of the main rod 11 and the sub-rod 12 of the thrust rod 1. The thrust rod 1 includes a main rod 11 and a sub-rod 12 hinged to the lower part of the main rod. The head parts of the main rod and the sub-rod are respectively provided with a first lateral connecting rod 111 and a second lateral connecting rod 121;

[0026] Among them, after the main rod 11 and the sub-rod 12 are hinged, they are connected in a V shape as shown in Figure 9 , and the included angle formed between the main rod 11 and the sub-rod 12 can become larger or smaller as the main rod 11 or the sub-rod 12 rotates around the hinge point, and the V shape also changes with the change of this included angle; the hinge connection structure between the main rod 11 and the sub-rod 12 is to provide a connecting ear with a hinge hole on the sub-rod 12 as shown in Figure 6 and 7, and is hinged to the main rod 11 through a pin shaft. The hinged connection method of the hinge point is a conventional structure in the prior art and will not be elaborated here; for the first transverse link 111 and the second transverse link 121, a pair of double connection ears are correspondingly arranged at the head of the main rod 11 or the auxiliary rod 12, and the first transverse link or the second transverse link is connected between the double connection ears. The connection method of the double connection ears to the cross bar is also a conventional structure in the prior art and will not be elaborated here;

[0027] See Figure 2 , 3 As shown in, the rotating clamping ring 2 includes two parts of a semi-ring, namely an upper rotating clamping ring 21 and a lower rotating clamping ring 22, a handle 23, a clamping groove 24, and a fixing bolt 25 arranged on the ring. When the two parts of the semi-ring are buckled, one side is connected together through the fixing bolt 25, and the other side is hinged through a pin shaft;

[0028] Among them, the fixing bolt 25 is connected to the pin shaft rod. See Figure 2 , 3 As shown in, one side of the upper rotating clamping ring 21 is provided with a double hinged ring with a spaced gap, and the other side is provided with a single hinged ring. One side of the lower rotating clamping ring 22 is provided with a connecting ear with a notch, and the other side is provided with a double hinged ring one with a spaced gap. When the two parts of the semi-ring are buckled, the single hinged ring of the upper rotating clamping ring 21 is inserted into the gap of the double hinged ring one of the lower rotating clamping ring 22 and is hinged through a pin shaft. The pin shaft rod connected by the fixing bolt 25 is hinged inside the double hinged ring of the upper rotating clamping ring 21, and the fixing bolt 25 is located in its spaced gap. The lower end of the fixing bolt is inserted into the notch of the connecting ear of the lower rotating clamping ring 22 and is connected and fixed through a nut; the handle 23 and the clamping groove 24 are symmetrically distributed on the two parts of the semi-ring. Figure 3 In, each of the two parts of the semi-ring is provided with a clamping groove 24 and two handles 23. The handles are rods for easy grasping and turning;

[0029] See Figure 4 , 5 As shown in, the fixed clamping ring 3 includes two parts of a semi-ring, namely an upper fixed clamping ring 31 and a lower fixed clamping ring 32, a pulling groove 33, a shaft 34, and a first fixing bolt 35; when the two parts of the semi-ring are buckled, one side is connected together through the first fixing bolt 35, and the other side is hinged through the shaft 34;

[0030] Among them, the connection method of the first fixing bolt 35 of the fixed clamping ring 3 and the hinged connection method of the other side through the shaft 34 are the same as the bolt connection and hinged connection methods and principles of the rotating clamping ring 2. See Figure 4 , 5 As shown in, it will not be elaborated here. The positions of the double hinged ring, the single hinged ring, and the connecting ear with a notch arranged in the two parts of the semi-ring are not limited, and the principle is to facilitate installation and use;

[0031] See Figure 1As shown, the fixed clamping ring 3 is clamped on the outer wall of the interface on the pipe body 100, and the rotating clamping ring 2 is clamped on the outer wall of the interface on the pipe body 200 to be bonded, leaving an insertion section. The draw groove 33 and the opening of the clamping groove 24 face away from each other in the reverse direction. The transverse connecting rod 111 of the main rod 11 of the thrust rod 1 is stuck in the draw groove 33 of the fixed clamping ring 3, and the transverse connecting rod 121 of the secondary rod 12 is stuck in the clamping groove 24 of the rotating clamping ring 2. Push the thrust rod 1 between the fixed clamping ring 3 and the rotating clamping ring 2 to pull the connected pipes to be inserted into each other.

[0032] See Figure 1 As shown, in the rotatable pipe clamp, the clamping groove 24 and the draw groove 33 are correspondingly arranged, which is convenient for applying axial force after the main rod 11 and the secondary rod 12 of the thrust rod 1 are stuck in.

[0033] See Figure 1 As shown, in the rotatable pipe clamp, two thrust rods 1 are symmetrically arranged, which is convenient for applying force with both hands to synchronously push forward on the circumference of the pipe.

[0034] See Figure 1 As shown, in the operation method of the rotatable pipe clamp, first open and position the fixed clamping ring 3. After positioning, fix the fixed clamping ring 3 on the pipe body 100 through bolts. The pipe body 1 is the connecting pipe section of the three-way pipe fitting pipeline. Use the same method to fix the rotating clamping ring 2 on the pipe body 200 to be bonded. The pipe body 2 is the straight pipe section pipeline. After the fixture is completed, the front end of the main rod 11 of the thrust rod 1 is stuck in the draw groove of the fixed clamping ring 3, and then the front end of the secondary rod 12 of the thrust rod is stuck in the clamping groove of the rotating clamping ring 2. After the upper and lower thrust rods are fixed, manually clamp the thrust rod towards the middle. At this time, the straight pipe section will complete the insertion action towards the three-way pipe fitting side. After the insertion action is completed, remove the upper and lower thrust rods, and then hold the handle 23 of the rotating clamping ring 2 to complete the rotation action of the straight pipe section.

[0035] After the rotation action is completed, loosen the bolts and remove the fixed clamping ring and the rotating clamping ring, and then perform the next operation of pipe bonding until the bonding is completed.
