Description

Technical Field

[0001] This utility model relates to the field of electrical conduit bending technology, and in particular to a building electrical conduit bending and shaping device. Background Technology

[0002] During the construction of building electrical conduits, bending and shaping tools are needed to bend PVC pipes, KBG pipes, etc., to specific angles to adapt to wiring requirements. Traditional bending and shaping tools have two major problems: First, the bending sleeve and the holding rod are mostly fixed connections, and one set of equipment can only adapt to two specifications of conduits. When the construction scenario requires bending conduits of different diameters, the entire bending and shaping tool must be replaced, which not only increases the cost of tool purchases but also requires carrying multiple bending and shaping tools. Second, the traditional holding rod has a fixed length and cannot be adjusted according to the construction worker's hand size, force application habits, or working space (such as narrow corners or high ceilings). This leads to inconvenience in applying force in some scenarios, easy deviation in bending angle, or increased operator fatigue due to uneven force on the hand, affecting construction quality and safety. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a building electrical conduit bending and shaping device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a building electrical conduit bending and shaping device, comprising a pipe bender, the pipe bender consisting of a holding rod and two bending sleeves, the holding rod comprising a rod body one and a rod body two, with one end of rod body one and rod body two fixedly connected, the bending sleeves being fixedly connected to one end of rod body one and rod body two via a locking assembly, each of the opposite ends of rod body one and rod body two having a slot, the bottom surface of the slot having a sliding groove, the locking assembly comprising a snap-fit ​​post, an L-shaped snap-fit ​​plate one, an L-shaped snap-fit ​​plate two, and a spring disposed inside the slot, and a first pressure rod and a second pressure rod fixedly connected to one side of L-shaped snap-fit ​​plate one and L-shaped snap-fit ​​plate two, the two ends of the spring being fixedly connected to L-shaped snap-fit ​​plate one and L-shaped snap-fit ​​plate two, and L-shaped snap-fit ​​plate one and L-shaped snap-fit ​​plate two being slidably disposed inside the sliding groove, the end of the snap-fit ​​post having a slot, the transverse sections of L-shaped snap-fit ​​plate one and L-shaped snap-fit ​​plate two being inserted into the slot and engaging with the slot.

[0005] Preferably, one end of the first rod is fixedly connected to a threaded rod, and one end of the second rod has a threaded groove, with the threaded rod threadedly connected inside the threaded groove.

[0006] Preferably, the pressing surfaces of the first and second pressure rods are evenly distributed with anti-slip protrusions.

[0007] Preferably, the transverse sections of both L-shaped card plate one and L-shaped card plate two have inclined surfaces facing the card slot.

[0008] Preferably, the inner wall of the slot is provided with a guide groove, and the outer wall of the snap-fit ​​post is fixedly connected with a guide rod, which is snapped inside the guide groove.

[0009] Preferably, the outer walls of both rod one and rod two are provided with anti-slip ribs distributed in a circular pattern.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a locking component, quick disassembly and assembly of the bent pipe sleeve and specification adaptation are achieved. When installing the bent pipe sleeve, the locking pin of the locking component is inserted into the slot. The end face of the slot at the end of the locking pin presses the inclined surface on the transverse section of L-shaped plate one and L-shaped plate two, causing the two plates to slide in opposite directions along the slide groove and compress the spring. When the locking pin is fully inserted, the spring returns to its original position and pushes the transverse section of the two plates into the slot, thereby fixing the locking pin to the holding rod and completing the installation of the bent pipe sleeve. When replacing, press the first and second pressure rods to drive the transverse section of the two plates out of the slot, and the locking pin can be pulled out to replace the bent pipe sleeve of the corresponding specification. This breaks the limitations of traditional fixed connection. One set of holding rods can be used with multiple specifications of bent pipe sleeves without replacing the entire equipment, greatly reducing tool procurement costs. The disassembly and assembly process does not require additional tools and can be completed simply by pressing the pressure rod.

[0011] 2. In this utility model, a threaded rod is fixed at one end of rod body one, and a threaded groove adapted to the threaded rod is opened at one end of rod body two. By rotating rod body one or rod body two, the depth of the threaded rod screwing into the threaded groove can be changed, thereby adjusting the overall length of the gripping rod according to the user's usage needs.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a building electrical conduit bending and shaping device, including a pipe bender, which consists of a holding rod 1 and two bending sleeves 2. The holding rod 1 includes a first rod body 101 and a second rod body 102, and one end of the first rod body 101 and the second rod body 102 are fixedly connected. The bending sleeves 2 are fixedly connected to one end of the first rod body 101 and the second rod body 102 through a locking assembly 3. The opposite ends of the first rod body 101 and the second rod body 102 are each provided with a slot 4. The bottom surface of the slot 4 is provided with a sliding groove 5. The locking assembly 3 includes a snap-fit ​​post 306, an L-shaped snap plate 301, an L-shaped snap plate 302 and a spring 303 installed inside the slot 4, and a first pressure rod 3 fixedly connected to one side of the L-shaped snap plate 301 and the L-shaped snap plate 302. 04 and the second pressure rod 305, the two ends of the spring 303 are fixedly connected to the L-shaped clamping plate 1 301 and the L-shaped clamping plate 2 302, and the L-shaped clamping plate 1 301 and the L-shaped clamping plate 2 302 are slidably arranged inside the slide groove 5. The end of the clamping post 306 is provided with a clamping groove 6. The transverse section of the L-shaped clamping plate 1 301 and the L-shaped clamping plate 2 302 is inserted into the groove 6 and engaged with the groove 6. One end of the rod body 101 is fixedly connected with a threaded rod 9, and one end of the rod body 2 102 is provided with a threaded groove 8. The threaded rod 9 is threadedly connected inside the threaded groove 8. The pressing surfaces of the first pressure rod 304 and the second pressure rod 305 are evenly distributed with anti-slip protrusions 11. The transverse section of the L-shaped clamping plate 1 301 and the L-shaped clamping plate 2 302 facing the groove 6 is provided with an inclined surface 12.

[0017] The beneficial effects achieved in this embodiment 1 are as follows: By setting the locking component 3, the bending sleeve 2 can be quickly disassembled and adapted to different specifications. When installing the bending sleeve 2, the locking pin 306 of the locking component 3 is inserted into the slot 4. The end face of the slot 6 at the end of the locking pin 306 presses the inclined surface 12 on the transverse section of the L-shaped plate 1 301 and the L-shaped plate 2 302, causing the two plates to slide in opposite directions along the slide groove 5 and compress the spring 303. When the locking pin 306 is fully inserted, the spring 303 returns to its original position and pushes the transverse section of the two plates into the slot 6, thus fixing the locking pin 306 to the holding rod 1, thereby completing the installation of the bending sleeve 2. This breaks the limitations of traditional fixed connections. One set of holding rod 1 can be used with multiple specifications of bending sleeve 2 without replacing the entire equipment, greatly reducing tool procurement costs. The threaded rod 9 is fixed at one end of the rod body 101, and the threaded rod 9 is opened at one end of the rod body 2. A threaded groove 8 adapted to the threaded rod 9 is provided. By rotating rod body 101 or rod body 102, the depth to which the threaded rod 9 is screwed into the threaded groove 8 can be changed, thereby adjusting the overall length of the grip rod 1 according to the user's needs. The anti-slip protrusions 11 on the pressing surfaces of the first pressure rod 304 and the second pressure rod 305 can increase the friction between the fingers and prevent slippage when pressing the first pressure rod 304 and the second pressure rod 305. Through the design of the inclined surface 12, when fixing the locking post 306, the end face of the locking groove 6 at the end of the locking post 306 presses the inclined surface 12 of the transverse section of the L-shaped locking plate 1 301 and the L-shaped locking plate 2 302, so that the two locking plates slide in opposite directions along the slide groove 5 and compress the spring 303, eliminating the need to press the pressure rod and reducing the operation steps. By inserting the guide rod 7 into the guide groove 13, the locking groove 6 and the slide groove 5 can be quickly aligned without further adjustment.

[0018] Example 2: Figure 2 - Figure 3 As shown, the inner wall of the slot 4 is provided with a guide groove 13, and the outer wall of the snap-fit ​​post 306 is fixedly connected with a guide rod 7, which is snapped inside the guide groove 13.

[0019] The beneficial effect achieved in this embodiment 2 is that the anti-slip ribs 10 on the outer walls of rod body 101 and rod body 202 can increase the friction when the hand grips the grip rod 1. This allows the anti-slip ribs 10 to increase the friction between the hand gripping rod body 1 and rod body 202 when the length of the grip rod 1 is adjusted by rotating the threaded rod 9, thus avoiding slippage when rotating the threaded rod 9 and affecting the adjustment efficiency.

[0020] The working principle of this embodiment is as follows: Before using the building electrical conduit bending and shaping tool, first select a suitable bending sleeve 2 according to the specifications of the conduit to be bent. When installing the bending sleeve 2, align the snap-fit ​​post 306 connected to the bending sleeve 2 with the slot 4 at the end of the holding rod 1, so that the guide rod 7 on the outer wall of the snap-fit ​​post 306 is aligned with the guide groove 13 on the inner wall of the slot 4. Then, insert the snap-fit ​​post 306 into the slot 4. During the insertion process, the end face of the snap groove 6 at the end of the snap-fit ​​post 306 presses against the inclined surface 12 of the transverse section of the L-shaped snap plate 1 301 and the L-shaped snap plate 2 302. This forces the two clamping plates to slide in opposite directions along the slide groove 5 and compress the spring 303. When the clamping post 306 is fully inserted into the slot 4, the spring 303 returns to its original shape, pushing the transverse sections of L-shaped clamping plate 1 301 and L-shaped clamping plate 2 302 into the slot 6 of the clamping post 306, thus completing the fixation of the bent pipe sleeve 2 and the holding rod 1. Then, according to the hand size, force application habits and working space of the construction personnel, rotate rod 1 101 or rod 2 102. By changing the screw depth of the threaded rod 9 in the threaded groove 8, the overall length of the holding rod 1 is adjusted. When it is necessary to replace the bent pipe sleeve 2 of different specifications, press the first pressure rod 304 and the second pressure rod 305 to drive the transverse sections of L-shaped clamping plate 1 301 and L-shaped clamping plate 2 302 out of the slot 6. Then pull out the clamping post 306. Repeat the above installation steps to complete the assembly of the bent pipe sleeve 2 of the new specification.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
