Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a general explosion-proof lighting distribution box for factories. Background Art

[0002] Explosion-proof distribution box is a kind of distribution box with explosion-proof characteristics. It is a kind of safety electrical equipment used in industrial environment. It is designed to provide safe power distribution for lighting and power lines in flammable, explosive or explosion-risk workplaces.

[0003] Most of the existing explosion-proof distribution boxes are not convenient for wiring work during use. A patent has also appeared in the prior art, which limits the wiring harness by changing the structure of the distribution box and setting a limit component, thereby reducing the influence of the wiring harness's own gravity on the wiring harness connection, so that the connection will not loosen easily. For example, a utility model patent with application number CN216436520U discloses an explosion-proof distribution box, including a distribution box body, the distribution box body includes a box body, four groups of sliding rods are installed on the inner wall of the box body, and fixed plates are slidably installed on the four groups of sliding rods. A limiting block is detachably installed on one end of the sliding rod, and the limiting block is set to a cylindrical structure. A handle is fixedly installed on one side of the fixed plate, and the handle is set at the edge position of the fixed plate. A wire threading hole is opened on one side of the bottom of the box body, and three groups of vertical plates are fixedly installed on one side of the bottom of the box body. The above-mentioned prior art uses a limit assembly to fix the wiring harness, but its fixing effect is not as good as the clamping and fixing effect, and when the wiring harness is not connected to the threading hole, the threading hole is in an open state. The unconnected threading hole will become an entry channel for external impurities. External dust and humid gas can enter the distribution box through the threading hole, increasing safety risks such as electrical failure and equipment damage. At the same time, when the lines are too long or too many, there is not enough storage space inside the distribution box, which can easily cause the internal line layout to be messy, lack of planning and organization, increase the risk of short circuit and fire, and pose a safety hazard, seriously endangering personal safety.

[0004] In view of this, the utility model proposes a universal explosion-proof distribution box for factories, which solves the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figure 1-2As shown, a general explosion-proof lighting distribution box for factories includes an explosion-proof distribution box body 1, a box cover 2 is installed on one side of the explosion-proof distribution box body 1, the box cover 2 can be rotatably connected to the explosion-proof distribution box body 1 in a hinged manner, and mounting blocks 3 are installed on both sides of the explosion-proof distribution box body 1, and the explosion-proof distribution box body 1 can be fixed to the factory wall by bolts penetrating the mounting blocks 3, and a fixing mechanism 4 is installed at the bottom of the explosion-proof distribution box body 1, and the fixing mechanism 4 can be fixed to the bottom of the box body 1 by bolts or welding, and a plurality of wiring holes 8 connected thereto are opened at the bottom of the explosion-proof distribution box body 1.

[0024] like Figure 3-4 As shown, the fixing mechanism 4 is fixed to the bottom of the explosion-proof distribution box body 1, and a plurality of wire entry holes 43 are provided on the fixing mechanism 4, and the plurality of wire entry holes 43 correspond to the plurality of wiring hole positions 8 one by one. A slide groove 42 is provided horizontally inside the fixing mechanism 4, and a plurality of balls 44 are arranged on the inner wall edge of the plurality of wire entry holes 43, and the plurality of balls 44 are distributed in a ring-shaped and equidistant manner. After the line passes through the wire entry hole and is connected to the electrical equipment in the explosion-proof distribution box body 1, when the line is too long, the excess line can be inserted into the accommodation area through the wiring hole 8, and the transverse partition 5 divides the interior of the box body 1 into a distribution room and a reserved chamber, and the top of the vertical partition 7 is fixedly connected to the bottom of the transverse partition 5, and the bottom of the vertical partition 7 is fixedly connected to the bottom of the box body 1, and the accommodation chamber is divided into a plurality of accommodation areas, and each accommodation area corresponds to a wiring hole 8, so as to achieve the purpose of storage and avoid mutual influence between adjacent lines.

[0025] like Figure 3-5 As shown, a slide groove 42 is horizontally opened inside the fixing mechanism 4, and a pair of movable plates 46 that can move toward or away from each other are arranged inside the slide groove 42. The fixing mechanism 4 is formed into a whole by welding after the movable plate 46 is installed. A plurality of springs 462 are installed on the outer side of the movable plate 46. The movable plate is fixedly connected to the inner wall of the slide groove 42 on each side through the spring 462, and a plurality of semicircular grooves 464 are respectively opened inside the movable plate 46. The wire holes formed by the semicircular grooves 464 correspond to the wire entry holes 43 one by one. An installation groove 465 is also opened in the semicircular groove 464. A sealing plate 466 is slidably connected inside the installation groove 465. A spring 2 467 is installed on the inner wall of the installation groove 465. The two ends of the spring 2 467 are respectively fixedly connected to the inner wall of the installation groove 465 and the sealing plate 466.

[0026] A rotating shaft 45 is installed on the opposite side of the movable plate 46. The rotating shaft 4 is fixed with connecting bolts through a round rod and exposed at the outer bottom of the fixing mechanism 4. The abutment block 47 is located between the two movable plates 46 and is connected to the rotating shaft 45. The corners of the abutment block 47 are chamfered. The other end of the two movable plates 46 close to each other is provided with a reserved groove 463 matching the abutment block 47. By rotating the rotating shaft 45 90°, the abutment block 47 is synchronously driven to slide.

When a line is connected to the wiring hole 8, the sealing plate 466 will be squeezed by the line and move into the installation groove 465 until the clamping cavity formed by the corresponding two semicircular grooves 464 abuts against the line, thereby achieving the effect of fixing multiple lines at the same time. However, when some wiring holes 8 are not connected to the line, the corresponding two sealing plates abut against each other under the elastic force of the spring 2 467, which can block the wire entry hole 43 to form a sealing structure, thereby reducing the probability of dust and humid gas entering the explosion-proof distribution box body 1.

[0028] It should be noted that the two movable plates 46 abut against each other under the elastic force of spring 1 462, and the elastic force of spring 1 462 is greater than the elastic force generated by spring 2 467, to ensure that when a line is connected to the wiring hole 8, the sealing plate 466 will be squeezed and moved by the line, and the two movable plates 46 can abut against each other.

[0029] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
