Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box convenient for installation. Background Art
[0002] The distribution box is the terminal equipment of the power distribution system, and electrical components such as air switches that can control the closing and opening of the circuit can be installed inside. In the prior art, the distribution box often needs to be installed on columns such as utility poles. In this case, a C-shaped steel section is provided at the rear side of the distribution box. The heads of two bolts are inserted into the C-shaped steel section from both ends. The two bolts respectively pass through the through holes at both ends of the pipe clamp and are connected to nuts. Tightening the nuts can clamp the column between the C-shaped steel section and the pipe clamp, thereby fixing the distribution box. During actual installation, it is necessary to first place the distribution box at the designated position on the column and hold it by hand. Then, insert the heads of the bolts into the C-shaped steel section from both ends. Then, respectively set the two through holes of the pipe clamp on the bolts. Then, screw the nuts onto the bolts by hand. When starting to screw the nuts onto the bolts, the nuts and bolts are not yet connected together. It is necessary to pinch the nut with the thumb and index finger and turn it. Due to the limitation of the joints, the nut can be turned more than 90° at a time. After that, release the nut with the fingers and return the wrist, and then pinch the nut to continue turning. However, due to reasons such as misalignment and inconvenient operation in aerial work, often after turning the nut about 90° for the first time, the nut is not successfully connected to the bolt, and the installer does not notice. Then, when the fingers are released, the nut will fall to the ground, and it is necessary to take out a new nut or go down to the ground to pick up the nut, which reduces the installation efficiency. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a distribution box convenient for installation in view of the above-mentioned existing technical deficiencies.
[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a distribution box convenient for installation, including a box body and a pipe clamp with through holes provided at both ends. A C-shaped steel section is provided at the rear side of the box body. It also includes a plug-in bolt. One end of the plug-in bolt is provided with a head. The width of the head is not greater than the distance between the two legs of the C-shaped steel section. The length of the head is not greater than the distance between the two middle legs of the C-shaped steel section. An angle is provided at a set of diagonals of the head. The distance between the two angles is not greater than the distance between the two middle legs of the C-shaped steel section. The distance between the other set of diagonals of the head is greater than the distance between the two middle legs of the C-shaped steel section. It also includes a nut used for threaded connection with the plug-in bolt.
[0005] Preferably, the angle is arc-shaped, and the center of the arc is on the axis of the plug-in bolt.
[0006] Preferably, chamfers are provided on two edges in the width direction on the side of the head away from the screw rod on the plug bolt.
[0007] Preferably, a groove penetrating the upper and lower surfaces is provided in the middle of the C-shaped steel section, and the cross-section of the groove is an isosceles triangle.
[0008] Beneficial effects: Since the width of the head of the plug bolt is not greater than the distance between the two calves of the C-shaped steel section, and its length is not greater than the distance between the two middle legs of the C-shaped steel section, a set of diagonals of the head is provided with a corner, and the distance between the other set of diagonals of the head is greater than the distance between the two middle legs of the C-shaped steel section, so that installers can insert the two plug bolts into the two through holes of the pipe clamp and connect the nuts on the ground. Therefore, when installing the distribution box on the column, the nuts will not fall off, saving steps and improving efficiency. Brief Description of the Drawings

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0015] Detailed Embodiments: In combination with Figures 1-4As shown in the figure, a distribution box that is easy to install includes a box body 1 and a pipe clamping plate 4 with through holes provided at both ends. A C-shaped steel section 2 is provided at the rear side of the box body 1. The number of C-shaped steel sections 2 is preferably two and they are respectively located at the upper and lower parts of the box body 1. It also includes a plug-in bolt 3. One end of the plug-in bolt 3 is provided with a head 31. The width of the head 31 is not greater than the distance between the two legs (i.e., the two short sides away from the box body 1 and parallel to the rear side of the box body 1) of the C-shaped steel section 2, so that the head 31 can be inserted into the C-shaped steel from between the two legs (without having to insert from both ends). The length of the head 31 is not greater than the distance between the two middle legs (i.e., the two sides perpendicular to the rear side of the box body 1) of the C-shaped steel section 2. A set of diagonals of the head 31 is provided with corners 311. The distance between the two corners 311 is not greater than the distance between the two middle legs of the C-shaped steel section 2, so that the included angle formed between the head 31 and the C-shaped steel section 2 can be relatively large, and thus the head 31 is not easily detached from the two legs of the C-shaped steel section 2. The distance between the other set of diagonals of the head 31 is greater than the distance between the two middle legs of the C-shaped steel section 2, so that when tightening the nut, the plug-in bolt 3 will not continuously rotate and thus the nut can be tightened. It also includes a nut for threadedly connecting with the plug-in bolt 3. During installation, when the installer is on the ground, the two plug-in bolts 3 can be respectively inserted into the two through holes of the pipe clamping plate 4, and then the bolts are screwed onto the plug-in bolts 3. Then one installer places the box body 1 at the designated position on the column 5 and holds it by hand. Then another installer holds one pipe clamping plate 4 with one hand and inserts the head 31 (with its length direction parallel to the extension direction of the C-shaped steel section 2) of a plug-in bolt 3 between the two legs of the C-shaped steel section 2 with the other hand. When the plug-in bolt 3 has a right-hand thread, the left corner 311 is located at its upper left corner and the right corner 311 is located at its lower right corner. When the plug-in bolt 3 has a left-hand thread, the left corner 311 is located at its lower left corner and the right corner 311 is located at its upper right corner. Then the plug-in bolt 3 is rotated by a certain angle until it can no longer rotate, and then the nut can be tightened. Then the head 31 (with its length direction parallel to the extension direction of the C-shaped steel section 2) of the other plug-in bolt 3 can be inserted between the two legs of the C-shaped steel section 2, and the nut tightening work can be completed according to the above steps. Then the installation work of the other pipe clamping plate 4 can be completed according to the above steps. Since the installer can insert the two plug-in bolts 3 into the two through holes of the pipe clamping plate 4 and connect the nut when on the ground, steps are saved when installing the distribution box in the air, and the nut will not fall off, improving the efficiency.
[0016] In this embodiment, the corner 311 is arc-shaped, and the center of the arc is on the axis of the plug-in bolt 3. The radius of the arc is close to half of the distance between the two middle legs of the C-shaped steel section 2. And the length of the head 31 is preferably close to the distance between the two middle legs of the C-shaped steel section 2, so that the length direction of the head 31 can be close to perpendicular to the extension direction of the C-shaped steel section 2.
[0017] In this embodiment, chamfers 312 are provided on two edges of the head 31 in the width direction on the side away from the screw on the plugging bolt 3, so that the head 31 can be more easily inserted between the two calves of the C-shaped steel section 2.
[0018] In this embodiment, a groove 21 penetrating the upper and lower surfaces is provided in the middle of the C-shaped steel section 2. The cross-section of the groove 21 is an isosceles triangle. When the box body 1 is placed at the designated position of the column 5, the column 5 is located in the groove 21, and at this time, the column 5 is located in the middle of the box body 1.
[0019] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
