[0082] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0083] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0084] Combine the following Figure 1 The structure of a pipe bending device 1000 provided in the present application is described.

[0085] The pipe bending device 1000 is used to bend the part of the pipe that needs to be bent. The bending operation usually requires a device for fixing the pipe and a device for providing bending force to the pipe. First, the part of the pipe bending device 1000 provided in the present application that is used to fix the pipe is described.

[0086] like Figure 1 As shown, the pipe bending device 1000 of the present application includes a pipe bending member, which further includes a first bending portion 101 and a second bending portion 102, wherein the first bending portion 101 and the second bending portion 102 cooperate with each other to provide a accommodating space for the portion to be bent of the target pipe 2000, where the accommodating space is referred to as a pipe accommodating cavity, and the formation of the pipe accommodating cavity is described below.

[0087] Among them, the first bending portion 101 includes multiple faces, and the multiple faces can be surrounded by a solid structure or a hollow structure, which is not limited here. One face of the first bending portion 101 that cooperates with the second bending portion 102 to form a pipe accommodating cavity is an arc surface. The reason why it is set as an arc surface is that when the part to be bent of the target pipe 2000 is bent from a straight state to an arc state, that is, when the part to be bent moves from away from the arc surface to the arc surface, the arc surface can increase the force-bearing area of ​​the part to be bent, ensuring that the outer wall of the part to be bent will not be deformed, dented, etc. At the same time, the design of the arc surface does not have a stress concentration point when the part to be bent is fitted, which can ensure the fluidity of the part to be bent.

[0088] Exemplarily, if the first bending portion 101 includes a first surface, a second surface, a third surface, and a fourth surface, one side of the first surface is connected to one side of the second surface, and the angle between the first surface and the second surface is greater than 90 degrees. Another side of the first surface is connected to one side of the third surface, and the angle between the first surface and the third surface is 90 degrees. The fourth surface is a curved surface, one side of the curved surface is connected to another side of the second surface, and another side of the curved surface is connected to another side of the third surface. It should be noted here that setting the angle between the first surface and the second surface to be greater than 90 degrees can make the second surface an inclined surface relative to the horizontal plane, so that the edge where the second surface meets the fourth surface will form a convex point 1014, and the part to be bent can be bent with the convex point 1014 as the starting point. Because the clockwise direction of the convex point 1014 is an arc surface, the height of the surface that is in contact with the part to be bent starting from the convex point 1014 and moving in a clockwise direction is in a continuously decreasing state, so it can cooperate with the part to be bent to be bent. In addition, compared with the setting of a plane plus an arc surface, this setting can shorten the bending distance and improve the bending efficiency.

[0089] It should be noted here that the shape of the first bending portion 101 is not limited to the above-mentioned shape, as long as it can cooperate with the second bending portion 102 to form a structure that can accommodate the part to be bent, and can cooperate with the second bending portion 102 to bend the part to be bent.

[0090] It is understandable that if the part to be bent is placed directly on the arc surface for bending, the part to be bent may be displaced when the second bending portion 102 provides a downward bending force, affecting the bending accuracy of the part to be bent. Based on this problem, the present application has only a first positioning structure 1011 on the arc surface where the part to be bent is placed, and the first positioning structure 1011 is used to limit the position of the part to be bent to prevent it from shifting. Exemplarily, the first positioning structure 1011 is, for example, a limiting groove provided on the arc surface, and the size of the limiting groove matches the part to be bent, so that the part to be bent will be stuck in the limiting groove to fix its position and avoid displacement under force. The opening range of the limiting groove can be from the raised point 1014 where the second surface and the fourth surface meet to the point where the fourth surface and the third surface meet.

[0091] In another embodiment, the first positioning structure 1011 is, for example, a limiting column arranged on the surface of the arc surface, and the number of the limiting columns includes at least two, and the two limiting columns can be arranged in a straight line along the width direction of the arc surface, or can be arranged in a staggered manner, which is not limited in the present application. Of course, in order to prevent the setting of the limiting column from affecting the bending effect of the portion to be bent, the height of the limiting column can be set to be slightly smaller than the diameter of the target pipe 2000.

[0092] The first positioning structure 1011 may also have other forms, which are not listed here in this application.

[0093] In another embodiment, since the prior art cannot control the bending angle of the tube when bending the tube, the manufactured medical tube has a poor performance when in use. In order to solve this problem, the present application provides a first angle scale area 1012 on the side adjacent to the first positioning structure 1011 and close to the side of the first positioning structure 1011 of the first bending portion 101. The first angle scale area 1012 is provided to facilitate the user who processes the tube to control the processing angle of the tube, so the first angle scale area 1012 is specifically provided on the side of the first bending portion 101 facing the user.

[0094] Exemplarily, from the above description of the structure of the first bending portion 101, it can be seen that the range of setting the first angle scale area 1012 can be from the raised point 1014 where the second surface and the fourth surface meet to the junction of the fourth surface and the third surface, that is, matching the length of the above-mentioned limit groove.

[0095] Continue as Figure 1 As shown, the second bending portion 102 is arranged at the upper part along the width direction of the pipe bending part, and its shape is similar to a horseshoe, including a fifth surface arranged opposite to the first positioning structure 1011 of the first bending portion 101. Since the fifth surface needs to cooperate with the surface where the first positioning structure 1011 is located to complete the bending operation of the part to be bent, the positional relationship between the fifth surface and the surface where the first positioning structure 1011 is located can be that the two surfaces are in conflict. It can be understood that since the surface where the first positioning structure 1011 is located is an arc surface, the fifth surface only conflicts with a part of the arc surface where the first positioning structure 1011 is located, and the other part is in a suspended state like the arc surface. When the fifth surface moves toward the arc surface, its movement trajectory is an arc, thereby realizing the bending of the part to be bent.

[0096] In order to better limit the position of the portion to be bent in the target pipe 2000 in cooperation with the first positioning structure 1011 provided on the first bending portion 101, a second positioning structure 1021 matching the first positioning structure 1011 is provided on the fifth surface of the second bending portion 102, and the second positioning structure 1021 is, for example, a linear groove, a limiting column, etc., which is not limited in the present application. The range of the linear groove is the length between the two side edges of the fifth surface along the length direction.

[0097] It can be understood that the arcuate movement of the fifth surface of the second bending portion 102 toward the first bending portion 101 is not just a single movement of the fifth surface, and the entire second bending portion 102 will move in the clockwise direction toward the arcuate movement of the first bending portion 101, but the movement directions of each surface of the second bending portion 102 will be different. Therefore, a force in the width direction is required to support the clockwise rotation of the second bending portion 102. In order to provide this force for the convenience of the user, continue as shown Figure 1 As shown, a gripping sub-portion 1023 is provided on the right side of the second bending portion 102 , and the user can place the force output part on the gripping sub-portion 1023 , and drive other parts of the second bending portion 102 to rotate through the gripping sub-portion 1023 .

[0098] In one embodiment, the gripping sub-portion 1023 may be detachably connected to the sixth surface on the right side of the second bending portion 102 or may be an integral part. The gripping sub-portion 1023 may be, for example, a cylindrical structure, and the position where it is connected to the sixth surface of the second bending portion 102 may be a structure matching the structure of the sixth surface, such as a rectangular connection block, a square connection block, etc., which are not limited here. The gripping sub-portion 1023 may be connected to the sixth surface by welding, bolt connection, clamping, embedded connection, etc., which are not limited here.

[0099] It can be understood that setting the holding sub-portion 1023 as a cylindrical structure can better match the user's output part (such as a hand) and improve the user's holding comfort.

[0100] In another optional embodiment, Figure 2 As shown, in order to further improve the convenience and comfort of holding, the present application provides an extended handle 1024 in the direction of the holding sub-portion 1023 away from the second bending portion 102. The function of the extended handle 1024 is to increase the length of the holding sub-portion 1023 to match the use of different users. Specifically, the shape of the extended handle 1024 matches the shape of the holding sub-portion 1023, and it is also a cylindrical structure. A force arm mounting groove 10241 is provided on its outer wall. In order to be able to fix the parent handle rod on the holding sub-portion 1023, a mounting protrusion matching the structure of the force arm mounting groove 10241 can be provided on the outer wall of the holding sub-portion 1023. Then, the protrusion can be clamped in the force arm mounting groove 10241 to achieve the connection between the holding sub-portion 1023 and the extended handle 1024.

[0101] It is understandable that the extended handle 1024 can be installed on the holding sub-portion 1023 and can also be removed from the holding sub-portion 1023, so it is more flexible to use. The user can selectively install or remove the extended handle 1024 according to the use environment, usage habits, etc.

[0102] In addition, in order to more accurately control the bending angle of the part to be bent, the present application can also be provided with a second angle scale area 1022 on the seventh surface on which the second bending portion 102 and the first angle scale area 1012 are located on a plane, and the range of the second angle scale area 1022 starts from the side end of the seventh surface away from the sixth surface until the line where the seventh surface intersects with the sixth surface. It can be understood that, because the second angle scale area 1022 needs to cooperate with the first angle scale area 1012 only to determine the bending angle of the part to be bent, the setting of the second angle scale area 1022 is the same as that of the first angle scale area 1012, that is, the first scale line of the second angle scale area 1022 and the first scale line of the first angle scale area 1012 are on the same straight line in the width direction, and the second scale line of the second angle scale area 1022 and the second scale line of the first angle area are on the same straight line in the width direction, and so on, which are not listed one by one.

[0103] After the first angle scale area 1012 and the second angle scale area 1022 are set, the user can obtain the bending angle of the portion to be bent by checking the angle scale at the intersection of the first angle scale area 1012 and the second angle scale area 1022 .

[0104] Illustratively, the pipe bending device 1000 provided in the present application can implement a bending of 0-105° on the portion to be bent.

[0105] The position where the second bending portion 102 intersects with the eighth surface opposite to the sixth surface and the ninth surface opposite to the seventh surface can be arc-shaped. Such a setting can improve the safety of the pipe bending device 1000.

[0106] In another embodiment, the eighth surface is the near-axial surface of the second bending portion, and the distance between the near-axial surface and the rotation axis of the second bending portion is smaller than the distance between the second positioning structure and the rotation axis of the second bending portion. With this arrangement, when placing the portion of the target pipe to be bent, the second bending portion can be first rotated counterclockwise so that the near-axial surface faces the arc-shaped first positioning structure side of the first bending portion, so that the gap between the surface to which the first positioning structure belongs and the second bending portion can be increased to facilitate the placement of the target pipe. After the target pipe is placed in place, the second bending portion is rotated clockwise to perform the bending operation on the target pipe.

[0107] In another optional embodiment, Figure 3 As shown, in order to make the first bending portion 101 and the second bending portion 102 better cooperate with each other, the first bending portion 101 and the second bending portion 102 can be both arranged on the bottom plate 20 to fix the positions of the first bending portion 101 and the second bending portion 102.

[0108] The bottom plate 20 is, for example, a rectangular parallelepiped structure, and includes a first mounting position, that is, a mounting position pre-set for mounting the first bending portion 101 and the second bending portion 102. The surface of the first bending portion 101 opposite to the surface where the first angle scale area 1012 is located is connected to the surface of the bottom plate 20 corresponding to the first mounting position, and the connection is, for example, welding, clamping, bolting, plugging, etc. Similarly, the surface of the second bending portion 102 opposite to the surface where the second angle scale area 1022 is located is connected to the surface of the bottom plate 20 corresponding to the first mounting position, and the connection is, for example, welding, clamping, bolting, plugging, etc.

[0109] In another optional embodiment, since the second bent portion 102 is provided with a gripping sub-portion 1023 on the right side surface along the width direction of the bottom plate 20, if the second bent portion 102 is directly mounted on the surface of the bottom plate 20 according to the above-mentioned mounting method, the gripping sub-portion 1023 may be too close to the surface of the bottom plate 20, which may cause the gripping part to be inconvenient. Figure 4As shown, the present application may be to set a mounting portion 80 between the first bending portion 101, the second bending portion 102 and the surface of the bottom plate 20, first connect the first bending portion 101 and the second bending portion 102 with the mounting portion 80, and then install the mounting portion 80 on the first mounting position. It is understandable that the mounting portion 80 needs to have a certain height to generate a certain distance between the second bending portion 102 and the surface of the bottom plate 20, so as to facilitate the user to use the gripping sub-portion 1023. Among them, the mounting portion 80 and the surface of the bottom plate 20 can be connected by welding, plugging, clamping, bolting, etc.

[0110] For example, the structure of the mounting portion 80 is an elliptical structure, and the mounting portion 80 can be formed integrally with the first bending portion 101 and rotatably connected to the second bending portion 102; the mounting portion 80 can also be plugged into the first bending portion 101 and rotatably connected to the second bending portion 102, etc. Of course, the mounting portion 80 can also be a rectangular parallelepiped, a cube, a polyhedron, etc., which is not limited here.

[0111] If the first bending portion 101 is plugged into the mounting portion 80, and the second bending portion 102 is rotatably connected to the mounting portion 80, then the mounting portion 80 may be provided with a first mounting axis and a second mounting axis, a first mounting through hole is opened at the center of the first bending portion 101, and a second mounting through hole is opened at the center of the second bending portion 102. The first mounting through hole is inserted into the first mounting through hole, and the second mounting through hole is inserted into the second mounting through hole, so that the first bending portion 101 and the second bending portion 102 can be connected to the mounting portion 80.

[0112] It is understandable that, since the second bending portion 102 is to perform a rotation operation, the second installation shaft is a cylinder, and the second installation through hole is also a cylindrical through hole matching the shape of the second installation shaft. Here, the shapes of the first installation shaft and the first installation through hole are not limited.

[0113] In another embodiment, Figure 5 As shown, in order to further fix the position of the pipe bending member 10 on the bottom plate 20, a connecting structure 1013 may be provided on the side of the lower bottom plate 20 near the bottom plate 20 of the first bending portion 101, and the connecting structure 1013 includes:

[0114] Mounting column 10131;

[0115] A first fixing structure 10132, the mounting column 10131 is slidably connected to the first fixing structure 10132, and the first fixing structure 10132 is mounted on a first mounting structure 201 disposed on the bottom plate 20;

[0116] The first fixed structure 10132 comprises a first structure 101321, a second structure 101322 and a third structure 101323, wherein the second structure 101322 is disposed between the first structure 101321 and the third structure 101323, wherein one long side of the first structure 101321 is connected to one long side of the second structure 101322, and another long side of the second structure is connected to one long side of the third structure 101323;

[0118] A through hole is provided inside the second structure 101322, and a slide groove is provided on the side wall of the through hole along the width direction of the bottom plate 20. The mounting column 10131 passes through the through hole and is slidably connected with the slide groove.

[0119] The first fixing structure 10132 is used to fix the mounting column 10131 on the surface of the bottom plate 20. The first fixing structure 10132 includes a first structure 101321 and a third structure 101323 that are in direct contact with and fixed to the surface of the bottom plate 20. The first structure 101321 and the third structure 101323 are, for example, rectangular parallelepiped structures. The surfaces of the first structure 101321 and the third structure 101323 facing the bottom plate 20 are in contact with the surface of the bottom plate 20. The first structure 101321 and the third structure 101323 may be provided with a plurality of bolt connection holes, and the surface of the bottom plate 20 corresponding to the bolt connection holes may also be provided with a plurality of bolt connection holes. After the first structure 101321 and the third structure 101323 are placed at predetermined positions on the bottom plate 20, the connection between the two can be achieved by screwing bolts into the bolt connection holes provided in the first structure 101321, the third structure 101323 and the bottom plate 20.

[0120] In another optional embodiment, Figure 6 As shown, a first mounting structure 201 is provided at a position on the base plate 20 for setting the first structure 101321 and the third structure 101323. The first mounting structure 201 is, for example, a mounting groove in which a slide rail is provided. The first structure 101321 and the second structure 101322 may be provided with a slide rail connecting portion matching the slide rail on the surface close to the base plate 20. The connection between the first structure 101321 and the second structure 101322 and the base plate 20 may be achieved by connecting the slide rail connecting portions of the first structure 101321 and the third structure 101323 to the slide rail in the mounting groove.

[0121] In addition, the first structure 101321 and the third structure 101323 can also slide along the slide rail to adjust the position of the first fixed structure 10132, so as to adapt to more application scenarios. It should be noted here that the slide rail connection portion provided on the first structure 101321 and the second structure 101322 also has a hovering function, so that the first structure 101321 and the second structure 101322 can be stationary on the slide rail after being adjusted to a predetermined position.

[0122] The second structure 101322 is arranged between the first structure 101321 and the third structure 101323, and the two sides of the second structure 101322 are respectively connected to one of the sides of the first structure 101321 and the third structure 101323, and the three can be integrally formed or can be connecting parts. The second structure 101322 includes three surfaces, two of which are arranged perpendicularly to the surface of the bottom plate 20, and the other surface is arranged parallel to the surface, and the three surfaces form a gate-shaped structure with a through hole facing the bottom plate 20, and the size of the through hole matches the mounting column 10131 arranged on the side of the lower bottom plate 20 of the first bending portion 101 close to the bottom plate 20, so that the mounting column 10131 can fix the first bending portion 101 by inserting it into the through hole of the second structure 101322.

[0123] In another optional embodiment, the second structure 101322 includes a first surface, a second surface and a third surface, one side of the second surface is movably connected to the side of the first surface or the third surface, or the second surface is snap-fitted to the first surface and hinged to the third surface. This arrangement can realize the opening or closing of the second surface, so as to facilitate the adjustment, cleaning and other operations of the first installation structure 201 when the second surface is opened.

[0124] In another optional embodiment, Figure 7 As shown, a resisting column 30 is arranged on the side opposite to the holding sub-portion 1023 near the second bending portion 102, and the resisting column 30 is installed on the bottom plate 20 or the mounting portion 80, and the surface of the resisting column 30 facing the lower bottom edge of the bottom plate 20 is on the same horizontal plane as the surface of the second bending portion 102 where the second positioning structure 1021 is arranged; a third positioning structure 301 is arranged on the surface of the resisting column 30 facing the lower bottom edge of the bottom plate 20, and the third positioning structure 301 can be the same structure as the second positioning structure 1021, that is, both are semicircular grooves. By arranging the resisting column 30, the part to be bent or other parts of the target pipe 2000 that is lifted into the first bending portion 101 and the second bending portion 102 can be further guided and limited in position, so as to prevent the target pipe 2000 from shifting. Exemplarily, the abutment column 30 is a rectangular parallelepiped structure, and the height of the rectangular parallelepiped structure in a direction perpendicular to the bottom plate 20 is the same as the height of the first bending portion 101 and the second bending portion 102, but the length and width of the rectangular parallelepiped are not limited.

[0125] In another alternative embodiment, continue as Figure 6 As shown, a second mounting structure 202 is also provided on the bottom plate 20, and the second mounting structure 202 includes at least two parallel sliding rails;

[0126] like Figure 8 As shown, the first support block 40 and the second support block 50 are installed on the second mounting structure 202, the first support block 40 is arranged between the second support block 50 and the pipe bending member 10, and the first support block 40 and the second support block 50 are slidably connected with the sliding track;

[0127] The first support block 40 comprises a first connecting portion 401 and a first boss 402, and a first limiting structure 4021 is arranged on the upper surface of the first boss 402;

[0128] The second supporting block 50 includes a second connecting portion 501 and a second boss 502 . A second limiting structure 5021 is disposed on the upper surface of the second boss 502 .

[0129] The first support block 40 and the second support block 50 are provided to support other parts of the target pipe 2000 that do not need to be bent, so as to better fix the position of the target pipe 2000 and improve the bending accuracy of the part to be bent in the target pipe 2000.

[0130] The first support block 40 and the second support block 50 are both T-shaped structures, the widths of the first support block 40 and the second support block 50 along the width direction of the bottom plate 20 are the same (that is, the widths of the first connection portion 401 and the second connection portion 501 are the same), and the upper side edges and lower side edges of the first connection portion 401 and the second connection portion 501 along the width direction of the bottom plate 20 are flush, and further, the upper side edges of the first connection portion 401 and the second connection portion 501 along the width direction of the bottom plate 20 are flush with the side edges of the second bending portion 102 close to the upper bottom edge of the bottom plate 20, and the lower side edges of the first connection portion 401 and the second connection portion 501 along the width direction of the bottom plate 20 are flush with the side edges of the first bending portion 101 close to the lower bottom edge of the bottom plate 20. Of course, this setting range can also be exceeded, and this application does not limit this. As long as the first limiting structure 4021 and the second limiting structure 5021 provided on the surface parallel to the bottom surface of the first supporting block 40 and the second supporting block 50 can support other parts of the target pipe 2000 without changing the original shape of the target pipe 2000. Exemplarily, the first limiting structure 4021 provided on the first boss 402 of the first supporting block 40 includes a first part 40211 and a second part 40212, the first part 40211 and the second part 40212 are connected, the size of the first part 40211 matches the size of the operating part (such as the cutting grinding head) provided in the target pipe 2000, and is used to support the operating part in the target pipe 2000, and the size of the second part 40212 matches the outer tube diameter of the target pipe 2000, and is used to support the outer tube connected to the operating part, then the sizes of the first part 40211 and the second part 40212 can be different. Of course, the shapes of the first portion 40211 and the second portion 40212 may also be the same as the shape of the end of the target pipe 2000 for operation when necessary. However, the target pipe 2000 may also have other shapes, and the specific shape of the first limiting structure 4021 is not limited here.

[0131] It is understandable that the first limiting structure 4021 is used to support the target pipe 2000, so the first limiting structure 4021 is an open structure, that is, the first limiting structure 4021 is a semicircular groove. Exemplarily, a fixing clip can also be provided on the first limiting structure 4021, and the soft head of the fixing clip is in contact with the first limiting structure 4021. The fixing effect of other parts of the target pipe 2000 is improved by providing a quick clip.

[0132] Similarly, the second limiting structure 5021 provided on the second boss 502 of the second support block 50 is also used to support other parts of the target pipe 2000. The second support block 50 is provided to prevent the target pipe 2000 from being too long. The part of the target pipe 2000 between the pipe bending part 10 and the first limiting structure 4021 sinks due to its own gravity, causing the target pipe 2000 to shift along the length direction of the base plate 20.

[0133] If the other parts of the target pipe 2000 supported by the second limiting structure 5021 are linear, then the second limiting structure 5021 is a linear semicircular groove, so the shape of the second limiting structure 5021 is related to the shape of the target pipe 2000, so the specific structure of the second limiting structure 5021 is not limited here.

[0134] Exemplarily, if the other parts of the target pipe 2000 are a straight line, then the outlet of the second limiting structure 5021 and the inlet of the first limiting structure 4021 can be arranged on a straight line, and the second limiting structure 5021 and the pipe accommodating cavity are on a straight line in the length direction of the bottom plate 20.

[0135] In another embodiment, continuing as Figure 6 As shown, the bottom plate 20 may be provided with a second mounting structure 202, and the second mounting structure 202 includes at least two parallel sliding rails, and the first connection portion 401 and the second connection portion 501 of the first support block 40 and the second support block 50 are slidably connected to the sliding rails. Therefore, the positions of the first support block 40 and the second support block 50 can be adjusted left and right according to the application scenario, etc., so as to better match the bending operation of the target pipe 2000 and improve the accuracy of the bending operation. It can be understood that the structure in which the first connection portion 401 and the second connection portion 501 are connected to the sliding rail also has a hovering function, so that the first support block 40 and the second support block 50 can be adjusted and fixed at a predetermined position.

[0136] In yet another alternative embodiment, continue as Figure 8 As shown, the third mounting structure 203 for mounting a limit slider 60 may be provided at the lower right corner of the bottom plate 20. The limit slider 60 is used to limit the range of rotation of the gripping sub-portion 1023 or the extended gripping handle 1024 in the clockwise direction toward the lower bottom edge of the bottom plate 20, that is, the gripping sub-portion 1023 or the extended gripping handle 1024 can only rotate to a position in contact with the limit slider 60.

[0137] The setting of the limit slider 60 is related to data such as the range of the first angle scale area 1012, the range of the second angle scale area 1022, the length of the gripping sub-portion 1023, the length of the extended handle 1024, etc. The setting position of the limit slider 60 on the base plate 20 can be set according to the specific application scenario, which is not limited here.

[0138] The limiting slider 60 includes a third connecting portion 601 and a third boss 602. The third connecting portion 601 is slidably connected to the third mounting structure 203. The third boss 602 is vertically arranged along the height direction of the base plate 20 at an end of the third connecting portion 601 away from the holding sub-portion 1023. The third connecting portion 601 and the third boss 602 form an L-shape. The third connecting portion 601 is used to fix the limiting slider 60 on the base plate 20, and the third boss 602 is used to limit the movement range of the holding sub-portion 1023 or the extended handle 1024.

[0139] Specifically, the movement range of the gripping sub-portion 1023 or the extended gripping handle 1024 is from the initial position to the side of the third boss 602 facing the third connecting portion 601. The initial position is the position where the gripping sub-portion 1023 or the extended gripping handle 1024 is disposed on the second bending portion 102 without being stressed.

[0140] In yet another alternative embodiment, continue as Figure 8 As shown, the pipe bending device 1000 provided by the present application can not only perform accurate bending operation on the to-be-bent portion of the target pipe 2000, but also detect the accuracy of the bent portion after bending, and the detection device is arranged on the fourth mounting structure 204 of the bottom plate 20. The fourth mounting structure 204 is located on the side of the bottom plate 20 close to the first support block 40, and the fourth mounting structure 204 is an open door-shaped structure, specifically, a door-shaped groove is opened along the side of the bottom plate 20 close to the first support block 40, and the groove faces the pipe bending part 10. The groove includes three inner arms, the first inner wall is close to the upper edge of the bottom plate 20, the third inner wall is close to the lower edge of the bottom plate 20, and the second inner wall is vertically arranged with the first inner wall and the second inner wall, and the two sides of the second inner wall are respectively connected with one end of the first inner wall close to the pipe bending part 10 and one end of the third inner wall close to the pipe bending part 10.

[0141] The angle measuring block 70 includes a first measuring block 701 and a second measuring block 702 . The first measuring block 701 is a rectangular parallelepiped structure, and the second measuring block 702 is a door-shaped structure. The shape of the second measuring block 702 matches the door-shaped groove opened in the fourth mounting structure 204 .

[0142] The inner walls of the second measuring block 702 are flush with the inner walls of the groove in the fourth mounting structure 204, and the first measuring block 701 is arranged on the upper surface of the second measuring block 702 close to the upper edge of the bottom plate 20. The first measuring block 701 and the second measuring block 702 can be an integral part or a connecting part.

[0143] The lower surface of the first measuring block 701 is fitted and connected to the base plate 20, and the upper surface of the first measuring block 701 is provided with a first placement area 7011 and a second placement area 7012 connected to the first placement area 7011. The first placement area 7011 is, for example, cylindrical, and the second placement area 7012 is, for example, trumpet-shaped. The purpose of setting the second placement area 7012 to the trumpet shape is to allow a certain error in the part to be bent.

[0144] like Fig. 9 As shown, Fig. 9 This is an application scenario diagram of the pipe bending device 1000 provided in this application, Fig. 9 It can be known that, currently, it is necessary to bend the portion of the target pipe 2000 close to the handle, and the target pipe 2000 can be inserted into the pipe accommodating cavity formed on the pipe bending piece from the right side of the pipe bending piece. Before the target pipe 2000 is inserted into the pipe accommodating cavity, the mounting column 10131 can be first slid downward along the slide rail provided on the inner wall of the first fixing structure 10132, so that a relatively large space is formed between the first bending portion 101 and the second bending portion 102, which is convenient for the insertion of the target pipe 2000. The target pipe 2000 is inserted into the pipe accommodating cavity and passes through the second limiting structure 5021 provided on the abutting column 30 and the second supporting block 50, and its end away from the handle is placed in the first limiting structure 4021 provided on the first supporting block 40, and the target pipe 2000 is inserted into the pipe accommodating cavity. 000 is successfully placed, and then the mounting column 10131 of the first bending portion 101 is slid upward to make the first bending portion 101 contact with the second bending portion 102, and the extended handle 1024 is held by hand to provide a force for the extended handle 1024 to move toward the lower bottom edge of the base plate 20, thereby driving the second bending portion 102 to move around the second mounting axis of the mounting portion 80 toward the arc surface of the first bending portion 101. At this time, the second angle scale area 1022 set on the second bending portion 102102 is respectively connected with different scales of the first angle scale area 1012, until the position where the second angle scale area 1022 intersects the first angle scale area 1012 is the predetermined bending angle of the part to be bent of the target pipe 2000, and then the force provided to the extended handle 1024 is stopped.

[0145] After the part to be bent of the target pipe 2000 is successfully processed through the above steps, the mounting column 10131 may be slid downward again along the slide rail provided on the inner wall of the first fixed structure 10132 to form a relatively large space between the first bending portion 101 and the second bending portion 102. After the target pipe 2000 is removed, the processed bent part of the target pipe 2000 is placed in the first placement area 7011 and the second placement area 7012 provided on the angle measuring block 70 to measure the bent part. When it is determined that the bent part can be placed in the first placement area 7011 and the second placement area 7012, it is determined that the processing of the target pipe 2000 is successful.

[0146] It is understandable that there may be multiple portions to be bent on the target pipe 2000 , and the bending operation and measurement operation of each portion to be bent can be found in the above description, which will not be elaborated here.

[0147] The present application provides a pipe bending device, which includes a pipe bending member, which further includes a first bending portion and a second bending portion; the first bending portion includes an arc-shaped first positioning structure and a first angle scale area arranged on a side adjacent to the first positioning structure; the second bending portion, the second positioning structure is arranged on the side opposite to the first positioning structure, the second angle scale area is arranged on the side connected to the first angle scale area, and a holding sub-portion is arranged on the side adjacent to the large angle area in the second angle scale area; when the part to be bent of the target pipe extends into the pipe accommodating cavity formed between the first positioning structure and the second positioning structure, the holding sub-portion drives the second bending portion to rotate when it moves toward the arc surface of the first bending portion, so as to form a preset bending angle of the part to be bent according to the first angle scale area and the second angle scale area. The part used for bending pipes in the pipe bending device provided in the present application is provided with an angle scale area. When the user is bending the part to be bent of the pipe, the user can control the bending angle of the part to be bent through the angle scale area, so that the error between the set angle of the part to be bent and the preset bending angle is smaller, thereby improving the processing accuracy of the pipe.

[0148] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of disclosure involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the aforementioned disclosed concept.
