Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinet installation, in particular to a pole device and a distribution box system supporting the pole device. Background Art

[0002] In the pole fixing operations in fields such as electric power and communication, traditional devices have significant technical defects: common rigid clamps have poor adaptability, are difficult to flexibly match cylindrical objects with different diameters, and require multiple people to cooperate in installation, resulting in low efficiency. For example, the currently widely used rigid clamps are formed by metal casting or welding, and their inner diameter sizes are fixed, and they can only adapt to cylindrical poles with specific diameters (such as Φ150mm or Φ200mm standard poles). When encountering non-standard poles or tapered poles (such as the 1:75 taper poles commonly used in communication towers), multiple sets of clamps with different specifications need to be configured, resulting in a material cost increase of more than 30%. Generally, at least two operators need to cooperate in the operation. This cooperation mode not only has low efficiency (the single installation takes about 25 minutes), but also greatly increases the risk of falling; Although the rope or chain bundling method can achieve circumferential fixation, there are hidden dangers of uneven tightening force and easy slippage, and adjusting the tightness requires repeated knotting or adjustment, which is time-consuming and laborious, and the uneven stress distribution is extremely likely to cause damage to the anti-corrosion layer on the pole surface; Although some bolt pressing devices can provide a large clamping force, the operating space is limited, and special tools are required for cooperation, making it difficult to meet the rapid clamping requirements in complex outdoor environments. In addition, the corresponding supporting distribution boxes are mostly located at high places outdoors. After long-term use, the conventional flat installation method is likely to become loose due to the thermal expansion and contraction caused by temperature changes.

[0003] In view of the above problems, we propose a pole device and a supporting distribution box system. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a pole device and a distribution box system supporting the pole device. By observing the tension degree of the steel belt and adjusting the rotation amount of the screw rod until the required tightening force is reached, rapid clamping and release of cylindrical objects are realized.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A pole holding device includes a fixing plate (1) and a steel belt (2). Both ends of the steel belt (2) are provided with hanging holes (201). One end of the fixing plate (1) is fixedly connected with a fixing pin (3), and the other end of the fixing plate (1) is provided with a vertical pole (4). A sleeve (5) is slidably sleeved on the vertical pole (4), and a movable pin (7) is fixedly connected to the side wall of the sleeve (5). The two ends of the steel belt (2) are respectively hung on the fixing pin (3) and the movable pin (7) through the corresponding hanging holes (201). A lead screw (6) is arranged on the vertical pole (4). The threaded end of the lead screw (6) is meshed and connected inside the vertical pole (4). A threaded hole adapted to the threaded end of the lead screw is opened inside the vertical pole (4). The threaded hole is coaxially arranged with the vertical pole (4). The threaded end of the lead screw (6) is meshed and connected in the threaded hole. When the lead screw (6) is rotated, the threaded end of the lead screw (6) is screwed into or out of the threaded hole. The end of the lead screw (6) is fixedly connected with a pressing cap (601) for pressing the sleeve (5). The threaded end of the lead screw (6) passes through the inner cavity of the sleeve (5) and is meshed in the threaded hole. A hexagonal convex block is fixedly connected to the center position of the pressing cap (601). The hexagonal convex block is adapted to an external wrench. Thus, by the cooperation of the external wrench and the hexagonal convex block, the lead screw (6) can be driven to rotate forward and backward. The lead screw can be adjusted by single - hand operation without complex tools. A inner support frame (10) is fixedly connected to the side of the fixing plate (1) close to the steel belt (2). Two abutting walls (1001) are symmetrically arranged on the inner support frame (10). The two abutting walls (1001) form a V - shaped structure, which is convenient for contacting the external rod body. In addition, gaskets can be additionally arranged on the surfaces of the two abutting walls (1001) to increase the friction force.

[0007] In a preferred embodiment: The fixing pin (3) includes a thin column (301) and a thick column (302), and the thin column (301) is fixedly connected with the thick column (302). The end of the thin column (301) away from the thick column (302) is fixedly connected to the fixing plate (1). The structure of the movable pin (7) is the same as that of the fixing pin (3). Among them, the hanging hole (201) includes a large hole (2011) and a small hole (2012). The large hole (2011) is communicated with the small hole (2012). The aperture of the large hole (2011) is larger than the outer diameter of the thick column (302). The aperture of the small hole (2012) is larger than the outer diameter of the thin column (301). The aperture of the small hole (2012) is smaller than the outer diameter of the thick column (302).

[0008] In a preferred embodiment: a receiving groove (101) is formed in the fixing plate (1). The receiving groove (101) is formed on the side of the fixing plate (1) away from the steel belt (2), and the receiving groove is formed along the length direction of the fixing plate (1). Two ends of the steel belt (2) respectively extend from the corresponding ends of the receiving groove (101) into the receiving groove (101). Preferably, the number of hanging holes at both ends of the steel belt (2) is multiple, and the multiple hanging holes at each end of the steel belt (2) are evenly distributed along the length direction of the steel belt (2). The fixing pin (3) and the movable pin (7) are respectively connected to the corresponding hanging holes (201).

[0009] In a preferred embodiment: a rotating block (8) is rotatably connected to the fixing plate (1), and the vertical rod (4) is fixedly connected to the rotating block (8).

[0010] The present invention also provides a distribution box system supporting the pole device, including a pole device. A base (11) is arranged outside the fixing plate (1), and the base (11) is fixedly connected by being inserted into the positioning plate (13) on the distribution box (12) in a matching manner.

[0011] In a preferred embodiment: the positioning plate (13) includes a bearing member (1301) and a moving member (1302). A movable pressing plate (1101) is arranged on the base (11), and the pressing plate (1101) moves to push against the abutting wall (1001), thereby ensuring the stability of the installation and fixation.

[0012] In a preferred embodiment: after the moving plate (1302) moves downward, it pushes the pressing plate (1101) to approach the abutting wall (1001), so as to make the pole device more stable synchronously when installing the distribution box.

[0013] In a preferred embodiment: the outer side surface of the abutting wall (1001) is thick at the top and narrow at the bottom. When the abutting wall (1001) is attached to the external rod body, the top of the distribution box (12) inclines downward, so that an included angle is formed between the force received by the distribution box in cooperation with the steel belt and the external rod body, improving the long-term stability of the installation.

[0014] In a preferred embodiment: a buffer spring (14) is arranged between the pressing plate (1101) and the abutting wall (1001) to achieve flexible fixation and relieve the stress change caused by thermal expansion and contraction.

[0015] In a preferred embodiment: a corrugated rib (202) is integrally stamped on the upper side edge of the middle part of the steel belt (2), which can open with the application of the pre-tightening force during the pre-tightening process, so as to meet the actual requirements of the inclined included angle and increase the contact area, improving the stability.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the present invention passes the steel belt around the cylindrical object to be fixed, hangs one end of the steel belt on the fixed pin, and hangs the other end on the movable pin. The operator rotates the screw rod clockwise, and the threaded end of the screw rod is screwed inward along the internal threaded hole of the vertical pole. The sleeve is pressed toward the vertical pole through the pressure cap. During the sliding process of the sleeve, the movable pin moves accordingly, pulling the steel belt to tighten, so that the steel belt fits tightly to the surface of the object being held. By observing the tension of the steel belt, adjust the rotation amount of the screw until the required tightening force is reached. When it needs to be loosened, rotate the screw counterclockwise to make the pressure cap eliminate the pressure on the sleeve. The sleeve can slide in the opposite direction on the vertical pole, and the steel belt can become loose, realizing the rapid clamping and release of cylindrical objects. It is suitable for temporary fixation of poles in the fields of electricity, communications, etc. In order to increase the stability of the installation, a matching distribution box system is proposed. The entire installation is achieved by squeezing and hanging the positioning plate and the base on the fixing plate. The operation during squeezing and hanging is used to push against the wall to further ensure the installation of the external pole. In addition, a structure with a certain tilt angle is set to increase the installation stability. In addition, the spring is used to buffer the pre-tightening and can also alleviate the stress changes caused by thermal expansion and contraction. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further descriptions of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0021] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application; as used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.

[0022] Please refer to Figures 1 - 16 , the present invention provides a technical solution: a holding rod device, including a fixed plate 1 and a steel strip 2. One end of the fixed plate 1 is fixedly connected with a fixed pin 3. As Figure 5 and Figure 6 shown, the fixed pin 3 is horizontally fixed on the fixed plate 1. The other end of the fixed plate 1 is provided with a vertical rod 4. A sleeve 5 is slidably sleeved on the vertical rod 4. A lead screw 6 is arranged on the vertical rod 4. The threaded end of the lead screw 6 is meshed and connected inside the vertical rod 4. As Figure 7As shown, a threaded hole adapted to the threaded end of the lead screw 6 is provided inside the vertical rod 4. The threaded hole is coaxially arranged with the vertical rod 4. The threaded end of the lead screw 6 is engaged and connected in the threaded hole. When the lead screw 6 is rotated, the threaded end of the lead screw 6 is screwed into or out of the threaded hole. A pressure cap 601 for pressing the sleeve 5 is fixedly connected to the end of the lead screw 6. The threaded end of the lead screw 6 passes through the inner cavity of the sleeve 5 and is engaged in the threaded hole. A hexagonal protrusion is fixedly connected to the central position of the pressure cap 601. The hexagonal protrusion is adapted to an external wrench. Thus, under the cooperation of the external wrench and the hexagonal protrusion, the lead screw 6 is driven to rotate forward and backward, and the lead screw 6 can be adjusted by single - hand operation without complex tools. And a movable pin 7 is fixedly connected to the side wall of the sleeve 5; Wherein, hanging holes 201 are provided at both ends of the steel belt 2. Both ends of the steel belt 2 are respectively hung on the fixed pin 3 and the movable pin 7 through the corresponding hanging holes 201. As Figures 2 - 4 and Figure 6 As shown, in order to further increase the stability of the holding pole, an inner support frame 10 is fixedly connected to the side of the fixed plate 1 close to the steel belt 2. Two abutting walls 1001 are symmetrically arranged on the inner support frame 10. The two abutting walls 1001 form a V - shaped structure, which can be adapted to most cylindrical external rod bodies.

[0023] During installation, the steel belt 2 is wound around a cylindrical object to be fixed (such as a telegraph pole). One end is hung into the fixed pin 3, and the other end is not connected temporarily. The threaded end of the lead screw 6 passes through the sleeve 5 and is screwed into the threaded hole of the vertical rod 4. At this time, the steel belt is in a relaxed state.

[0024] During fixation, the operator clips the external wrench onto the hexagonal protrusion of the pressure cap 601 and rotates the lead screw 6 clockwise. The threaded end of the lead screw 6 is screwed inward along the internal threaded hole of the vertical rod 4. The sleeve 5 is pressed towards the vertical rod 4 through the pressure cap 601. During the sliding process of the sleeve 5, the movable pin 7 moves accordingly, pulling the steel belt 2 to tighten, so that the steel belt 2 closely adheres to the surface of the object held by the pole. By observing the tension degree of the steel belt 2, the rotation amount of the lead screw 6 is adjusted until the required tightening force is reached. When it needs to be loosened, rotating the lead screw 6 counterclockwise can eliminate the pressing of the pressure cap 601 on the sleeve 5. The sleeve 5 can slide reversely on the vertical rod 4, and the steel belt 2 can become loose, realizing the rapid clamping and release of the cylindrical object, which is applicable to the scenario of temporary fixation of rod bodies in the fields of electric power, communication, etc.

[0025] As Figures 1 - 7 As shown, in order to enable the stable connection between the fixed pin 3 (or the movable pin 7) and the hanging hole 201, the fixed pin 3 includes a thin column 301 and a thick column 302. The thin column 301 and the thick column 302 are fixedly connected. The end of the thin column 301 away from the thick column 302 is fixedly connected to the fixed plate 1. The structure of the movable pin 7 is the same as that of the fixed pin 3; Wherein, the hanging hole 201 includes a large hole 2011 and a small hole 2012. The large hole 2011 communicates with the small hole 2012. The aperture of the large hole 2011 is larger than the outer diameter of the thick column 302. The aperture of the small hole 2012 is larger than the outer diameter of the thin column 301, and the aperture of the small hole 2012 is smaller than the outer diameter of the thick column 302.

[0026] When one end of the steel belt 2 is hung on the fixed pin 3, first move the end of the steel belt 2 so that the hanging hole 201 moves to the position of the fixed pin 3, align the large hole 2011 with the thick column 302, then pass the thick column 302 into the large hole 2011 and relatively move the steel belt 2 and the fixed pin 3. At this time, the thin column 302 moves into the interior of the small hole 2012. In this state, it can ensure the stable connection between the hanging hole 201 and the fixed pin 3 and prevent the two from falling off. The connection method between the movable pin 7 and the hanging hole 201 is the same as that between the fixed pin 3 and the hanging hole 201.

[0027] As Figures 1 - 6 shown, in order to enable the steel belt 2 to hoop cylindrical objects of different sizes, the number of hanging holes 201 at both ends of the steel belt 2 is multiple. The multiple hanging holes 201 at each end of the steel belt 2 are evenly distributed along the length direction of the steel belt 2. The fixed pin 3 and the movable pin 7 are respectively connected to the corresponding hanging holes 201.

[0028] As Figures 4 - 7 shown, in order to be able to accommodate the redundant parts at the ends of the steel belt 2, a receiving groove 101 is provided on the fixing plate 1. The receiving groove 101 is opened on the side of the fixing plate 1 away from the steel belt 2. The receiving groove 101 is opened along the length direction of the fixing plate 1. The two ends of the steel belt 2 respectively extend from the corresponding ends of the receiving groove 101 into the receiving groove 101.

[0029] As Figure 7 shown, in order to conveniently extend the end of the steel belt 2 close to the movable pin 7 into the receiving groove 101, a rotating block 8 is rotatably connected to the fixing plate 1. The vertical rod 4 is fixedly connected to the rotating block 8. Before hanging the movable pin 7 on the hanging hole 201, first rotate the rotating block 8. At this time, the rotating block 8 drives the vertical rod 4 to turn to one side, so as to expose the end of the receiving groove 101, which is convenient for extending the redundant part at the end of the steel belt 2 into the receiving groove 101. Then rotate the rotating block 8 again and reset the vertical rod 4. In this state, hang the movable pin 7 on the corresponding hanging hole 201, and then rotate the screw rod 6 to realize the tightening of the steel belt 2.

[0030] As Figure 7As shown, in order to prevent the lead screw 6 from driving the sleeve 5 to rotate during rotation, thereby achieving the limitation of the angular position of the movable pin 7 relative to the hanging hole 201, two guide rods 9 are symmetrically and fixedly connected to both sides of the rotating block 8 and located on both sides of the column 4, and two ear blocks 501 are symmetrically and fixedly connected to both sides of the sleeve 5, and the two ear blocks 501 are respectively sleeved on the two guide rods 9.

[0031] Specifically, the installation and connection method of the holding pole device and the supporting distribution box system is that a base 11 is arranged outside the fixing plate 1, and the base 11 is fixedly connected by being inserted into the positioning plate 13 on the distribution box 12 in a matching manner.

[0032] The fixing methods at least include the following two: Method 1: As Figure 8 shown, two groups of positioning plates 13 are arranged on the back of the distribution box 12, and the two groups of positioning plates 13 are driven by a lead screw 15. As Figure 7 shown, threads with opposite directions are respectively arranged at both ends of the lead screw 15, that is, by rotating the lead screw 15 (the position at the top or bottom can be used for operation, similar to the operation of the compression cap 601), the positioning plates 13 can move closer to the middle (the upper plate and the lower plate of the positioning plate 13 move closer), thereby clamping the base 11; Of course, similarly, the number of the positioning plates 13 can also be one or more, and the principle is similar to the operation of the compression cap 601.

[0033] In actual use, the actual distance between the two fixing plates 1 is fixed in this way of using two groups of positioning plates 13. Therefore, for this reason, when using two or more fixing plates 1 (corresponding to the same number of steel belts 2), a connecting rod 16 with a fixed length can be pre-connected between the two fixing plates 1. As Figure 8 shown, the length of the connecting rod 16 here is equal to the distance between the two fixing plates 1 when they are clamped by the positioning plates 13, so that the cumbersome measurement steps during installation can be omitted.

[0034] When two or more fixing plates 1 (corresponding number of steel belts 2, etc.) are used in actual application, obviously the operation amount doubles, and since the external rod bodies are all horizontally squeezed, the increase in the number does not have a very obvious effect on increasing the pre-tightening friction effect.

[0035] Therefore, a more advantageous way of supporting the distribution box system is proposed: using a single positioning plate 13, wherein the positioning plate 13 includes a bearing member 1301 and a moving member 1302. As Figure 16As shown, the carrier 1301 is stationary and fixedly connected to the back of the distribution box 12. The moving part 1302 is movable and slidably connected to the back of the distribution box 13. The moving part 1302 is driven up and down by the rotation of the wire shaft 15 (similar to the previous method, guide rods for sliding and limiting are also provided on both sides).

[0036] And an active pressing plate 1101 is provided on the base 11 (at a different height from the storage groove 101, which does not affect the winding of the steel strip 2). The structures of the moving plate 1302 and the pressing plate 1101 are as Figure 12 shown. The contact positions of both are inclined planes. In this way, after the moving plate 1302 moves downward, it pushes the pressing plate 1101 closer to the abutting wall 1001 (the abutting wall 1001 is slidably connected to the inner support 10 but cannot be separated). That is, the pressing plate 1101 moves to push the abutting wall 1001, and the abutting wall 1001 moves to further press the external rod, completing the more stable fixation of the distribution box system.

[0037] Since distribution boxes are mostly installed and fixed in open-air locations, and when the temperature difference changes greatly after installation, thermal expansion and contraction may cause loosening, and the extrusion contact between the abutting wall 1001 and the external rod is a hard extrusion. Therefore, a further optimization method is proposed.

[0038] Specifically: a buffer spring 14 is provided between the pressing plate 1101 and the abutting wall 1001, that is, the force is transmitted between the two through the buffer spring 14 to achieve a buffering effect. And when the temperature difference changes greatly, for example, when the temperature decreases, the steel strip 2 shrinks and becomes tighter. At this time, the buffer spring 14 will also shrink, so as to compensate for a certain amount of deformation of the steel strip 2 and reduce the stress, preventing the steel strip 2 from breaking due to excessive force; when the temperature rises, the steel strip 2 becomes longer and the pre-tightening force becomes looser. At this time, the buffer spring 14 will also become larger, that is, it exerts a greater elastic force on the abutting wall 1001 to make up for the loosening caused by the elongation of the steel strip 2.

[0039] Of course, in order to prevent the buffer spring 14 from being overly bent, a thin rod 1102 is fixedly provided on the pressing plate 1101, and corresponding holes are provided on the abutting wall 1001. The thin rod 1102 is slidably inserted into the holes, and the buffer spring 14 is sleeved outside the thin rod 1102.

[0040] On the basis of the above method, an installation method of a single fixing plate 1 (steel strip 2) is proposed to improve the safety efficiency while ensuring stability. Specifically, the outer side surface of the abutting wall 1001 is thicker at the top and narrower at the bottom, that is, it has an angle (5 - 10 degrees). When the abutting wall 1001 is close to the external rod, the top of the distribution box 12 tilts downward, and the tilting angle is as Figure 15Within the range of 5 to 10 degrees, it is a slightly inclined installation prevention method where the bottom edge of the distribution box contacts the external rod (which can be correspondingly set). In this case, the steel belt 2 is not horizontally strapped. Due to the inclination, the weight of the distribution box will generate a certain overturning force, which will further squeeze the external rod, thereby further improving the installation stability. To avoid the reduction of the contact area between the steel belt 2 and the rod caused by the inclination, a corrugated rib 202 is integrally stamped on the upper side edge of the middle part of the steel belt 2. During the process of tightening the steel belt 2 and pressing down the moving part 1302, it can deform to increase the contact with the external rod and improve the friction strength. The flattened drawing of the steel belt 2 before stamping is as follows Figure 13 , and the perimeter difference between its inner and outer arcs provides a margin for forming the corrugated rib. Moreover, this steel belt 2 with different upward and downward stretching amounts can be applied to the installation of some tapered rods.
