Technical Field

[0001] The utility model relates to the technical field of pipe bending, in particular to a simple small pipe bender. Background Art

[0002] For some metal pipes, they need to be bent into different shapes according to the actual usage scenarios during use, such as U-shape, arc shape, etc., which requires the use of mechanical equipment such as pipe benders or pipe bending machines. However, most of the existing sales and factory use are hydraulic pipe bending machines, CNC pipe bending machines or fully automatic pipe bending machines. However, since these devices are controlled by electric hydraulics, the equipment size is often large, so they are only suitable for use in large spaces such as maintenance workshops. They are not suitable for small spaces such as aerial construction platforms, and they do not have the characteristics of flexible operation.

[0003] Therefore, it is necessary to invent a simple small pipe bender to solve the above problems. Utility Model Content

[0004] In order to solve the shortcomings of the prior art, the purpose of the utility model is to provide a simple small pipe bender, which solves the problem that the pipe bending equipment in the prior art is often large in size due to electric hydraulic control, and is therefore only suitable for use in large space venues such as maintenance workshops, and is not suitable for use in small spaces such as high-altitude construction platforms, and does not have the characteristics of flexible operation.

[0005] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0006] A simple small pipe bender comprises a table plate which can be detachably mounted on a high-altitude construction platform and a retaining ring welded to a non-mounting surface of the table plate, a lever member is rotatably provided on the portion of the non-mounting surface of the table plate located inside the retaining ring, the rotation center of the lever member is concentric with the retaining ring, a U-shaped retaining ring which can lock the sliding distance is longitudinally slidably provided on the portion of the non-mounting surface of the table plate located above the retaining ring, the pipe to be bent is clamped between the outer side surface of the retaining ring and the end support surface of the U-shaped retaining ring, the lever member comprises a rotating column which is rotatably abutted against the non-mounting surface of the table plate and is concentric with the retaining ring, a cross bar connected to the peripheral side wall of the rotating column, and an extrusion column which is connected to the peripheral side wall of the cross bar close to the table plate and contacts the side wall of the pipe to be bent, and dials which can record the bending curvature of the pipe are detachably embedded at symmetrical positions on the non-mounting surface of the table plate.

[0007] As a preferred solution of the utility model, a portion of the non-installation surface of the table plate located inside the retaining ring is welded with an internally hollow positioning cartridge, and the positioning cartridge is concentrically arranged with the retaining ring, and the rotating column is rotatably inserted into the positioning cartridge.

[0008] As a preferred solution of the utility model, the portion of the platform located above the retaining ring is longitudinally provided with two guide grooves, the slider can slide longitudinally along the guide grooves, and the slider is locked in the longitudinal sliding position in the guide grooves by a first locking bolt.

[0009] As a preferred solution of the utility model, the table top is detachably mounted to the aerial construction platform via second locking bolts at four corners.

[0010] As a preferred solution of the utility model, the side of the extrusion column away from the cross bar is in sliding contact with the non-installation surface of the table plate.

[0011] As a preferred solution of the utility model, the longitudinal sliding range of the slider is 0-30 mm, and the scale range of the dial is 0-90 degrees.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] Compared with hydraulic pipe bender, CNC pipe bender or full-automatic pipe bender and other equipment, the pipe bender in the utility model has a smaller shape and lighter weight. Under the premise of meeting the requirements of simple and small structure, it does not require electric hydraulic control, so it can be more easily moved or installed on high-altitude construction platforms, and is more suitable for sites with narrow spaces such as high-altitude construction platforms. In actual use, the longitudinal spacing between the U-shaped retaining ring and the retaining ring can be changed by forcing the U-shaped retaining ring to slide longitudinally, that is, changing the distance between the clamping surfaces of the two, so as to facilitate flexible clamping adjustment according to the diameter of the pipe fitting, and at the same time, it can be manually applied to the horizontal force to change the longitudinal spacing between the retaining ring and the retaining ring. The rod is used to drive the rotating column to rotate, thereby driving the extrusion column to rotate, thereby gradually contacting the clamped pipe and forcing the pipe to gradually fit the U-shaped butt ring clamping surface through further rotation, and the rotating column can rotate in both clockwise and counterclockwise directions, thereby squeezing and fitting the pipe to the U-shaped butt ring clamping surface on both sides, and the clockwise or counterclockwise rotation angle can be read by the dial, and finally the initial straight pipe is bent into U-shaped, arc-shaped and other curved pipes with various angles and shapes by manual force. Therefore, it has the characteristics of flexible pipe bending operations in narrow space sites such as high-altitude construction platforms. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0019] The utility model provides Figure 1-Figure 2 The simple small pipe bender shown in the figure comprises a table plate 1 which can be detachably mounted on a high-altitude construction platform and a retaining ring 4 welded to a non-mounting surface of the table plate 1. The portion of the non-mounting surface of the table plate 1 located inside the retaining ring 4 is rotatably provided with a lever member, the rotation center of the lever member is concentric with the retaining ring 4, and the portion of the non-mounting surface of the table plate 1 located above the retaining ring 4 is longitudinally slidably provided with a U-shaped retaining ring 10 with a lockable sliding distance, the pipe to be bent is clamped between the outer side surface of the retaining ring 4 and the end support surface of the U-shaped retaining ring 10, and the lever member comprises a rotating A rotating column 5 is movably abutted against the non-installation surface of the table 1 and concentric with the retaining ring 4, a cross bar 6 is connected to the side wall of the rotating column 5, and an extrusion column 7 is connected to the side wall of the cross bar 6 close to the table 1 and in contact with the side wall of the pipe to be bent. A dial 2 for recording the bending curvature of the pipe can be removably embedded in the symmetrical position of the non-installation surface of the table 1. The rotating column 5, cross bar 6 and extrusion column 7 of the lever member are F-shaped as a whole, have the characteristics of flexibility and detachability, and can greatly reduce the manual force required for bending the pipe through the lever principle.

[0020] The portion of the non-installation surface of the table plate 1 located inside the retaining ring 4 is welded with an internal hollow positioning cartridge 3, and the positioning cartridge 3 is concentrically arranged with the retaining ring 4. The rotating column 5 is rotatably inserted into the positioning cartridge 3, and manual force is applied to the cross bar 6 to drive the rotating column 5 to rotate in the positioning cartridge 3, thereby forcing the extrusion column 7 to make an arc motion around the center of the rotating column 5, so that the extrusion column 7 gradually contacts the pipe fitting and forces the pipe fitting to gradually fit the clamping surface of the U-shaped retaining ring 10 through further rotation.

[0021] Two guide grooves 8 are longitudinally provided on the portion of the table 1 above the retaining ring 4, and the slider 9 can slide longitudinally along the guide groove 8, and the slider 9 is locked in the longitudinal sliding position in the guide groove 8 by a first locking bolt 11. The longitudinal sliding of the slider 9 along the guide groove 8 can change the longitudinal distance between the U-shaped retaining ring 10 and the retaining ring 4, that is, change the distance between the two clamping surfaces, to adapt to pipe fittings of different diameters.

[0022] The table plate 1 is detachably mounted on the aerial construction platform via second locking bolts 12 at four corners.

[0023] The side of the extrusion column 7 away from the cross bar 6 is in sliding contact with the non-installation surface of the table 1, and the end face of the extrusion column 7 is always in contact with the non-installation surface of the table 1, thereby ensuring the distance between the cross bar 6 and the table 1 and preventing the rotating column 5 from deviating during rotation.

[0024] The longitudinal sliding range of the slider 9 is 0-30 mm, and the scale range of the dial 2 is 0-90 degrees.

[0025] Compared with hydraulic pipe bender, CNC pipe bender or fully automatic pipe bender, the pipe bender in the utility model has a smaller shape and lighter weight. Under the premise of meeting the requirements of simple and small structure, it does not require electric hydraulic control, so it can be more easily moved or installed on high-altitude construction platforms, and is more suitable for sites with narrow spaces such as high-altitude construction platforms. In actual use, the longitudinal spacing between the U-shaped retaining ring 10 and the retaining ring 4 can be changed by forcing the U-shaped retaining ring 10 to slide longitudinally, that is, changing the distance between the clamping surfaces of the two, so as to facilitate flexible clamping adjustment according to the diameter of the pipe fitting, and at the same time, it can be manually applied to the cross bar 6. The rotating column 5 is driven to rotate, thereby driving the extrusion column 7 to rotate, thereby gradually contacting the clamped pipe and forcing the pipe to gradually fit the clamping surface of the U-shaped butt ring 10 through further rotation, and the rotating column 5 can rotate in both clockwise and counterclockwise directions, thereby squeezing and fitting the pipe to the clamping surface of the U-shaped butt ring 10 on both sides, and the clockwise or counterclockwise rotation angle can be read by the dial 2, and finally the initial straight pipe is bent into U-shaped, arc-shaped and other curved pipes of various angles and shapes by manual force. Therefore, it has the characteristic of flexible pipe bending operation in narrow space sites such as high-altitude construction platforms.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
