Description

Technical Field

[0001] The utility model relates to the field of plastic pipe processing tools, in particular to a pipe bending tool used for plastic pipes. Background Art

[0002] Plastic pipe bending equipment is mainly used to bend plastic pipes into specific angles for easy assembly.

[0003] At present, since plastic pipe bending equipment is usually a pipe bending machine, it has a large size and is difficult to carry and use. Therefore, when performing assembly work on site, the pipe bending operation is generally performed manually by assembly workers. The shape accuracy of the pipe after bending is low, and it is easy to have a bending shape close to a right angle at the bending part, which affects the strength of the bent part of the plastic pipe after bending, is inconvenient for plastic pipe assembly operations, and the pipe bending process is relatively laborious, which affects the improvement of assembly efficiency.

[0004] Based on this, the utility model provides a pipe bending tool for plastic pipes, which improves its portability so that it can be conveniently carried and used outside, thereby achieving the purpose of improving the strength of the plastic pipe after bending and improving on-site assembly efficiency. Utility Model Content

[0005] Based on this, it is necessary to provide a pipe bending tool for plastic pipes, comprising a horizontally arranged base plate, the upper surface of the base plate forming a mounting surface, the mounting surface being vertically provided with a support rod, the support rod being provided with a cross rod, the cross rod being arranged along the left and right directions, and the left end of the cross rod being connected to the support rod; a first mounting groove is also formed on the mounting surface of the base plate, the first mounting groove is formed by a local recess of the base plate, the first mounting groove is located on the right side of the cross rod, and the length direction of the first mounting groove is arranged along the front-back direction; a mounting bracket is fixedly arranged in the first mounting groove, the mounting bracket is rotatably provided with a mounting rod, the surface of the mounting rod is provided with an external thread and the mounting rod is arranged along the front-back direction, and the mounting rod is also provided with a connecting seat, the connecting seat is sleeved on the mounting rod and threadedly connected to the external thread on the mounting rod; a stop rod is vertically provided on the top of the connecting seat, the stop rod is cylindrical, and the left and right side walls of the connecting seat are in contact with the side walls of the first mounting groove and are slidably matched with the side walls of the mounting groove.

[0006] The present invention has a simple structure for a pipe bending tool that is convenient for carrying and using. The crossbar of the pipe bending tool is fixed to the base plate via a support rod. The crossbar is used to insert the plastic pipe to be bent. After the plastic pipe is inserted onto the crossbar, a stopper provided on the connecting seat can block and limit the plastic pipe. The plastic pipe can be bent by contacting the stopper and bending the plastic pipe around the stopper. The entire process is simple to operate and saves time and effort. During this process, due to the blocking of the stopper, the bent portion of the plastic pipe bends along the surface of the stopper. Therefore, the cylindrical stopper guides the bending of the plastic pipe, making the bent portion of the plastic pipe an arc. Compared to a bend formed by manual bending that is approximately a right angle, the present invention can improve the strength of the bent portion of the plastic pipe after it is bent. It is worth noting that the bent portion of the pipe to be bent needs to be heated during the bending process, for example, by using a heat gun to heat the bent portion.

[0007] In the present invention, the connecting seat where the baffle rod is located is connected to the mounting rod by threaded cooperation. Therefore, the connecting seat can be moved forward and backward by rotating the mounting rod, thereby realizing the adjustment of the front and rear position of the baffle rod and adjusting the distance between the baffle rod and the cross bar. Then, the baffle rod can just abut the surface of the pipe sleeved on the cross bar. It can be seen that the present invention can be applied to the bending operation of plastic pipes of different thicknesses.

[0009] In the present invention, the blocking rod can be set on the connecting seat so as to swing backward, and the support rod can be set on the first mounting seat so as to swing forward. Therefore, the blocking rod and the support rod can both swing toward the mounting surface of the base plate, so as to achieve the blocking rod and the support rod being close to the mounting surface, which can effectively reduce the space occupied by the pipe bending tool, thereby improving its portability. Among them, the blocking rod can be set on the connecting seat so as to swing backward. Therefore, when bending the plastic pipe, it is necessary to make the plastic pipe abut against the rear side of the blocking rod and bend the plastic pipe in the forward direction so that the blocking rod can block and limit the plastic pipe. At this time, the force exerted by the plastic pipe on the cross bar is backward. Therefore, the movable structure that allows the support rod to swing forward will not affect the pipe bending process.

[0010] Furthermore, a threaded mounting hole is provided on the connecting seat corresponding to the mounting rod, and the threaded mounting hole is sleeved on the mounting rod and is threadedly matched with the mounting rod; a first socket is vertically provided on the top of the connecting seat, and the first socket extends backward from the connecting seat, and a first receiving groove is formed on the connecting seat, and a first rotating shaft is rotatably provided in the first receiving groove, and the first rotating shaft is arranged along the left and right directions, and the bottom end of the blocking rod is fixedly provided on the first rotating shaft, and the front side of the blocking rod abuts against the front side wall of the first receiving groove.

[0011] In the present invention, the connecting seat is threadedly connected to the mounting rod through the threaded mounting hole thereon. Therefore, through the rotation of the mounting rod and the limiting effect of the side wall of the first mounting groove on the connecting seat, the connecting seat can drive the blocking rod thereon to move back and forth in the front and rear directions.

[0012] In the present invention, the blocking rod is fixedly connected to the first rotating shaft through its bottom end so that it can be swung backward on the connecting seat, wherein the front side wall of the first accommodating groove blocks the blocking rod to prevent the blocking rod from swinging forward.

[0013] Furthermore, a second socket is provided at the top of the first mounting seat, and the second socket extends forward from the first mounting seat, forming a second receiving groove on the first mounting seat, and a second rotating shaft is rotatably provided in the second receiving groove, and the second rotating shaft is provided along the left and right directions, and the bottom end of the support rod is fixedly provided on the second rotating shaft, and the rear side of the support rod abuts against the rear side wall of the second receiving groove.

[0014] In the present invention, the support rod is fixedly connected to the second rotating shaft through its bottom end so that it can be set on the connecting seat in a forward swinging manner, wherein the rear side wall of the second accommodating groove has a blocking effect on the blocking rod to prevent the blocking rod from swinging backward.

[0015] Furthermore, a second mounting groove is provided on the mounting surface corresponding to the first mounting seat, the second mounting groove is formed by a partial recess of the bottom plate, and the first mounting seat is fixedly arranged at the bottom of the second mounting groove; a second accommodating cavity is also formed on the mounting surface corresponding to the second mounting groove, the second accommodating cavity is formed by a partial recess of the bottom plate, the second accommodating cavity is located at the front side of the second mounting groove and is communicated with the second mounting groove, and the second accommodating cavity matches the shape of the combined structure of the support rod and the cross rod, and is used to accommodate the support rod and the cross rod; a first accommodating cavity is also formed on the mounting surface corresponding to the first mounting groove, the first accommodating cavity is formed by a partial recess of the bottom plate, the first accommodating cavity is located at the rear side of the first mounting groove and is communicated with the first mounting groove, and the first accommodating cavity matches the shape of the baffle rod, and is used to accommodate the baffle rod.

[0016] In the present invention, the second accommodating cavity is used to accommodate the support rod and the cross bar thereon when the support rod swings forward, so that the support rod and the cross bar can be completely stored in the bottom plate. Similarly, the baffle bar can also be completely stored in the first accommodating cavity when it swings backward. Therefore, the present invention can further reduce the space occupancy rate of the pipe bending tool. At the same time, it can also make the surface structure of the pipe bending tool smoother, which can further facilitate the carrying of the pipe bending tool.

[0017] Furthermore, a threaded mounting hole is provided at the top end of the support rod corresponding to the cross rod, and a threaded section is provided at the left end of the cross rod corresponding to the threaded mounting hole. The cross rod is detachably mounted on the threaded mounting hole of the support rod through the threaded section at its left end.

[0018] In the present invention, the cross bar is detachably fixedly connected to the support bar through the threaded section at its left end. Therefore, the cross bar on the support bar is replaceable. By preparing cross bars of different diameters, cross bars of different diameters can be selected when bending plastic tubes of different inner diameters, so that the outer wall of the cross bar and the inner wall of the plastic tube can fit more closely, thereby achieving the purpose of reducing the deformation of the plastic tube during the bending process.

[0021] Furthermore, it also includes a storage box, which includes a bottom box and a top box. The rear ends of the bottom box and the top box are pivotally connected to each other through a hinge structure, and the front ends of the bottom box and the top box are connected to each other through a snap structure.

[0027] 2. In the utility model, the cross bar of the pipe bending tool is fixed to the base plate through the support bar, and the cross bar is used to insert the plastic pipe to be bent. After the plastic pipe is put on the cross bar, the stop bar arranged on the connecting seat can block and limit the plastic pipe. At this time, the plastic pipe is abutted against the stop bar and the plastic pipe is bent around the stop bar, so the pipe bending operation of the plastic pipe can be completed. The whole process is simple to operate, saving time and effort. During this process, due to the obstruction of the stop bar, the bent part of the plastic pipe will bend along the surface of the stop bar. Therefore, the cylindrical stop bar will guide the bending of the plastic pipe, making the bent part of the plastic pipe an arc shape. Compared with the bent part formed by manual bending and approximately at a right angle, the utility model can make the bent part of the plastic pipe have better strength after being bent and formed.

[0028] 3. In the present invention, the connecting seat where the baffle rod is located is connected to the mounting rod by threaded cooperation.

The surface of the mounting rod 331 is provided with an external thread and the mounting rod 331 is arranged along the front and rear directions. A connecting seat 31 is also provided on the mounting rod 331, and the connecting seat 31 is sleeved on the mounting rod 331 and is threadedly connected to the external thread on the mounting rod 331; a blocking rod 32 is vertically provided on the top of the connecting seat 31, and the blocking rod 32 is cylindrical, and the left and right side walls of the connecting seat 31 fit into the side walls of the first mounting groove 12 and are slidably matched with the side walls of the mounting groove.

[0036] The pipe bending tool of the present invention has a simple structure and can be conveniently carried and used. The crossbar 23 of the pipe bending tool is fixed to the base plate 1 through the support rod 22. The crossbar 23 is used to insert the plastic pipe to be bent. After the plastic pipe is inserted into the crossbar 23, the stopper 32 provided on the connecting seat 31 can block and limit the plastic pipe. At this time, the plastic pipe is abutted against the stopper 32 and the plastic pipe is bent around the stopper 32 to complete the pipe bending operation. The whole process is simple to operate and saves time and effort. During this process, due to the obstruction of the stopper 32, the bent portion of the plastic pipe will bend along the surface of the stopper 32. Therefore, the cylindrical stopper 32 will guide the bending of the plastic pipe, so that the bent portion of the plastic pipe is in an arc shape. Compared with the bent portion formed by manual bending and approximately at a right angle, the present invention can make the bent portion of the plastic pipe have better strength after being bent. It is worth noting that during the bending process, the bent portion of the pipe to be bent needs to be heated, for example, by using a hot air gun to heat the bent portion.

[0037] In the present invention, the connecting seat 31 where the baffle rod 32 is located is threadedly connected to the mounting rod 331. Therefore, the connecting seat 31 can be moved forward and backward by rotating the mounting rod 331, thereby adjusting the front and rear positions of the baffle rod 32 and adjusting the distance between the baffle rod 32 and the cross bar 23, so that the baffle rod 32 can just abut the surface of the pipe sleeved on the cross bar 23. It can be seen that the present invention is suitable for bending operations of plastic pipes of different thicknesses.

[0038] In one embodiment, the blocking rod 32 is vertically arranged on the connecting seat 31, and the blocking rod 32 can be pivotally connected to the connecting seat 31 so as to swing backward; a first mounting seat 21 is fixedly arranged on the mounting surface corresponding to the support rod 22, and the support rod 22 is vertically arranged on the first mounting seat 21, and the support rod 22 can be pivotally connected to the mounting seat so as to swing forward.

[0039] In this embodiment, the blocking rod 32 can be set on the connecting seat 31 so as to swing backward, and the support rod 22 can be set on the first mounting seat 21 so as to swing forward. Therefore, the blocking rod 32 and the support rod 22 can both swing toward the mounting surface of the base plate 1, so that the blocking rod 32 and the support rod 22 are close to the mounting surface, which can effectively reduce the space occupied by the pipe bending tool, thereby improving its portability. Among them, the blocking rod 32 can be set on the connecting seat 31 so as to swing backward. Therefore, when bending the plastic pipe, it is necessary to make the plastic pipe abut against the rear side of the blocking rod 32 and bend the plastic pipe in the forward direction so that the blocking rod 32 can block and limit the plastic pipe. At this time, the force exerted by the plastic pipe on the cross bar 23 is backward. Therefore, the movable structure of the support rod 22 that can swing forward will not affect the pipe bending process.

[0041] In this embodiment, the connecting seat 31 is threadedly connected to the mounting rod 331 through the threaded mounting hole thereon. Therefore, through the rotation of the mounting rod 331 and the limiting effect of the side wall of the first mounting groove 12 on the connecting seat 31, the connecting seat 31 can drive the blocking rod 32 thereon to move back and forth in the front and rear directions.

[0042] In this embodiment, the blocking rod 32 is fixedly connected to the first rotating shaft through its bottom end so that it can be swung backward on the connecting seat 31, wherein the front side wall of the first accommodating groove 311 blocks the blocking rod 32 to prevent the blocking rod 32 from swinging forward.

[0046] In this embodiment, the second accommodating chamber 13 is used to accommodate the support rod 22 and the cross bar 23 thereon when the support rod 22 swings forward, so that the support rod 22 and the cross bar 23 can be completely stored in the base plate 1. Similarly, the blocking rod 32 can also be completely stored in the first accommodating chamber 14 when it swings backward. Therefore, the utility model can further reduce the space occupancy rate of the pipe bending tool. At the same time, it can also make the surface structure of the pipe bending tool smoother, which can further facilitate the carrying of the pipe bending tool.

[0048] In this embodiment, the cross bar 23 is detachably fixedly connected to the support rod 22 through the threaded section 231 at its left end. Therefore, the cross bar 23 on the support rod 22 is replaceable. By preparing cross bars 23 of different diameters, cross bars 23 of different diameters can be selected when bending plastic tubes of different inner diameters, so that the outer wall of the cross bar 23 can fit more closely with the inner wall of the plastic tube, thereby achieving the purpose of reducing the deformation of the plastic tube during the bending process.
