[0002] Plumbing is the system that delivers water to a building and removes wastewater from it, and sewer hookups are the process of connecting sewer pipes together so that wastewater can flow from fixtures, such as sinks, toilets, and showers, into the sewer system.

[0003] There are many ways to connect water supply and drainage pipes. Among them, adhesive connection is the simplest way to connect pipes. It is mostly used for connecting water supply and drainage pipes such as PVC, CPVC and ABS. During actual construction, the adhesive is applied as a bonding material on the outside of the edge of the pipe connection, and then the water supply and drainage pipe is inserted into one end of the connecting pipe. After the adhesive is cured, both ends of the connecting pipe are drawn into the water supply and drainage pipe to complete the connection.

[0004] In the prior art, after two water supply and drainage pipes are butt-jointed, the connecting pipe needs to be rotated so that the adhesive on the outside of the water supply and drainage pipes can be evenly applied. However, the connecting pipe is usually rotated directly by hand, and no supporting structure is provided for the connecting pipe. It is difficult to rotate a larger connecting pipe manually. If the rotation time is too long, the adhesive will dry out and the bonding effect will deteriorate, thereby affecting the sealing effect of the joint of the water supply and drainage pipes. Summary of the invention

[0005] The purpose of the utility model is to provide a drainage pipe auxiliary connection device, which can support the water supply and drainage pipe when it is docked with the connecting pipe, avoid manual rotation of the connecting pipe, so as to save physical strength. At the same time, the adhesive is applied in time and evenly to prevent the adhesive from drying and affecting the sealing effect, thereby ensuring the sealing effect of the joint between the connecting pipe and the water supply and drainage pipe, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drainage pipe auxiliary connection device, comprising a base and a screw drive unit arranged inside the base, characterized in that: a screw drive unit is provided with a twisting component on the upper side, and a locking component is provided on the upper side of the base;

[0008] Preferably, the two movable grooves are cross-opened on the outer surface of the drum, and the width of the movable groove is the same as the diameter of the cross section of the guide rod.

[0009] Preferably, the positioning assembly includes a through hole opened on the left side of the base, the through hole passes through the base, and anti-slip grooves are opened inside the through hole.

[0010] Preferably, a rotating groove is opened on the right side of the base, a rotating ring is rotatably connected inside the rotating groove, the right side of the rotating ring is fixedly connected to an end of the rotating drum close to the base, and the shape of the rotating groove is adapted to the shape of the rotating ring.

[0011] Preferably, the locking component comprises a plurality of sliding grooves provided on the outside of the positioning cylinder, a positioning block is slidably connected in each of the plurality of sliding grooves, and the shape of the sliding grooves matches the shape of the positioning block.

[0012] Preferably, the positioning block is in a trapezoidal shape, the sliding groove is opened obliquely from left to right, and the sliding groove and the positioning block are both arranged in a ring array on the outside of the positioning cylinder.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 5 , a drainage pipe auxiliary connection device, comprising a base 1 and a screw drive unit 2 arranged inside the base 1, characterized in that: a screw drive unit 2 is provided with a twisting component 3 on the upper side, and a locking component 4 is provided on the upper side of the base 1;

[0029] The screwing component 3 includes a sleeve 31 fixedly connected to the upper side of the screw drive unit 2, and two guide rods 32 are fixedly connected to the inner wall of the sleeve 31. A rotating cylinder 33 is arranged inside the sleeve 31, and two movable grooves 34 are provided on the outer side of the rotating cylinder 33. The two guide rods 32 are respectively slidably connected in the two movable grooves 34, and a positioning cylinder 35 is slidably connected inside the right end of the rotating cylinder 33. An installation groove 36 is provided at the end of the positioning cylinder 35 away from the base 1, and a positioning component 37 is provided at the end of the sleeve 31 close to the base 1.

[0030] Two moving grooves 34 are cross-shaped and opened on the outer surface of the rotating drum 33 . The width of the moving grooves 34 is the same as the diameter of the cross section of the guide rod 32 .

[0031] The positioning assembly 37 includes a through hole 371 formed on the left side of the base 1 . The through hole 371 passes through the base 1 , and an anti-slip groove is formed inside the through hole 371 .

[0032] A rotating groove 372 is provided on the right side of the base 1 , and a rotating ring 373 is rotatably connected inside the rotating groove 372 . The right side of the rotating ring 373 is fixedly connected to an end of the rotating drum 33 close to the base 1 , and the shape of the rotating groove 372 matches the shape of the rotating ring 373 .

[0033] By adopting the above technical solution, the connecting pipe is first placed in the installation groove 36 on the right side of the positioning cylinder 35, and then the connecting end of the water supply and drainage pipe coated with adhesive is inserted into the connecting pipe in the installation groove 36. After the connecting pipe is locked in the rotating cylinder 33 by the locking component 4, the connecting end of the other water supply and drainage pipe coated with adhesive is inserted from the through hole 371 on one side of the base 1, and then enters the rotating cylinder 33 and is inserted into the other end of the positioning cylinder 35, and the two water supply and drainage pipes are respectively inserted into the two ends of the connecting pipe;

[0034] The screw drive unit 2 can then be started. Since the screw drive unit 2 is composed of a servo motor, a screw and a screw nut, when the output end of the servo motor drives the screw to rotate, the screw nut on the outside of the screw will start to move inside the base 1 according to the thread direction of the outside of the screw. Since the screw nut is fixed on the outside of the sleeve 31, when the screw drives the screw nut to rotate, the sleeve 31 will also move with the screw nut. Then, during the movement of the sleeve 31, the two guide rods 32 inside the sleeve 31 are inserted into the two moving grooves 34 outside the rotating cylinder 33. Since the sleeve 31 always ensures linear movement, the two guide rods 32 generate a rotational force during the movement inside the two moving grooves 34, driving the rotating cylinder 33 to rotate inside the sleeve 31, and the positioning cylinder 35 is locked inside the rotating cylinder 33 by the locking component 4;

[0035] Anti-slip grooves are provided in the mounting groove 36. When the rotating drum 33 rotates, the positioning cylinder 35 inside the rotating drum 33 will also rotate synchronously with the rotating drum 33, and drive the connecting pipe to rotate on the outside of the two water supply and drainage pipes, so that the adhesive between the connecting pipe and the water supply and drainage pipe is evenly applied. During the rotation of the rotating drum 33, the rotating ring 373 on the left side of the rotating drum 33 will always rotate inside the rotating groove 372 on the right side of the base 1, and support the rotating drum 33. Since the two water supply and drainage pipes are respectively inserted into the two ends of the rotating drum 33, the two water supply and drainage pipes can be supported when docking with the connecting pipe, making the pipe connection step easier and avoiding manual rotation of the connecting pipe to save physical strength. At the same time, the adhesive is evenly applied in time to prevent the adhesive from drying up and affecting the sealing effect, thereby ensuring the sealing effect of the joint between the connecting pipe and the water supply and drainage pipe.

[0036] Specifically, Figure 4 and Figure 5 As shown, the locking component 4 includes a plurality of sliding grooves 41 disposed outside the positioning tube 35 , and a positioning block 43 is slidably connected in each of the plurality of sliding grooves 41 . The shape of the sliding grooves 41 matches the shape of the positioning block 43 .

[0037] The positioning block 43 is in a trapezoidal shape, and the sliding groove 41 is opened obliquely from left to right. The sliding groove 41 and the positioning block 43 are both arranged in an annular array on the outside of the positioning tube 35.

[0038] The inner wall of the rotating drum 33 is provided with a plurality of positioning grooves 42 , and positioning blocks 43 are slidably connected in the plurality of positioning grooves 42 . The shape of the positioning grooves 42 matches the shape of the positioning blocks 43 , and the plurality of positioning grooves 42 are respectively connected with the plurality of sliding grooves 41 .

[0039] Two return springs 44 are fixedly connected to one side of the positioning block 43 away from the positioning tube 35 , and the other end of the return spring 44 is fixedly connected to the inner cavity of the positioning groove 42 .

[0040] By adopting the above technical solution, first, when the right water supply and drainage pipe is inserted into the positioning cylinder 35, the positioning cylinder 35 will be squeezed and move in the direction of the positioning block 43. During the movement of the positioning cylinder 35, the positioning block 43 will be in the sliding groove 41 outside the positioning cylinder 35, and the positioning block 43 squeezed by the positioning cylinder 35 will enter the positioning groove 42. When the positioning block 43 cannot continue to move inside the positioning groove 42, the positioning cylinder 35 will be blocked by the part of the positioning block 43 that has not entered the positioning groove 42. At the same time, the return spring 44 in the positioning groove 42 will always squeeze the positioning block 43, so that the multiple positioning blocks 43 distributed on the outside of the positioning cylinder 35 clamp the positioning cylinder 35 and are restricted from moving by the water supply and drainage pipe.

[0041] Then, after the two water supply and drainage pipes are respectively inserted into the two ends of the connecting pipe from both sides of the rotating drum 33, the left water supply and drainage pipe enters the through hole 371 and contacts the anti-skid pattern, and the right water supply and drainage pipe enters the installation groove 36 and contacts the anti-skid pattern. When the rotating drum 33 drives the connecting pipe to rotate through the positioning cylinder 35, the two water supply and drainage pipes will be restricted by the anti-skid pattern and difficult to rotate smoothly. In the process of pulling the connecting pipe out of the positioning cylinder 35, as the positioning cylinder 35 loses the restriction of the water supply and drainage pipe, the positioning cylinder 35 will be pulled so that the positioning block 43 gradually slides in the sliding groove 41 outside the positioning cylinder 35. In this process, the return spring 44 will also push the positioning block 43 and push the positioning block 43 outward. The brake under the base 1 can drive the rotating drum 33 to disengage from the other water supply and drainage pipe. Since the locked positioning cylinder 35 can drive the connecting pipe to rotate, the docking of the two water supply and drainage pipes can be smoother, and the positioning cylinder 35 can be freely removed from the inside of the rotating drum 33, which can facilitate the replacement of positioning cylinders 35 with different inner cavity diameters, making the connection of water supply and drainage pipes with different diameters more convenient.

[0042] Working principle: First, the water supply and drainage pipe on the left side is drawn into the rotating drum 33 through the through hole 371 and connected to the connecting pipe inside the positioning cylinder 35, and the two water supply and drainage pipes are inserted from the installation groove 36 on the right side of the positioning cylinder 35 and the other end of the connecting pipe. When the water supply and drainage pipe on the right side pushes the positioning cylinder 35, as the positioning cylinder 35 moves inside the rotating drum 33, the positioning block 43 will slide into the positioning groove 42 through the sliding groove 41, and squeeze the positioning pipe block with the help of the return spring 44 inside the positioning groove 42, so that the positioning cylinder 35 is limited. When the screw drive unit 2 drives the sleeve 31 to move linearly After that, the guide rod 32 inside the sleeve 31 will slide in the movable groove 34 outside the rotating drum 33, and generate a rotational force to drive the rotating drum 33 to rotate. After the rotating drum 33 rotates, it will drive the connecting pipe to rotate outside the two water supply and drainage pipes, so that the adhesive between the water supply and drainage pipes and the connecting pipes is evenly spread. When taking out the right water supply and drainage pipe, the positioning cylinder 35 can be taken out after losing the restriction of the water supply and drainage pipe. At this time, the positioning block 43 will always slide in the movable groove 34 outside the positioning cylinder 35 through the reset spring 44, and the base 1 will be taken out from the other water supply and drainage pipe through the brake wheel below it.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
