Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-7: the utility model provides a heat dissipation box structure of cable branch case, includes box 1, is provided with two cooling blower 2 in the inside of box 1 side by side, and a door body 3 articulates at the front end of box 1 through the hinge to through locking mechanical system 4 and 1 locking connection of box. At the both sides of box, respectively detachable installs heat dissipation filter core 5, heat dissipation filter core 5 constitute by the shell body 51 and the interior casing 52 that can peg graft the combination each other, all be formed with a plurality of heat dissipation fretworks holes on shell body 51 and the interior casing 52, shell body 51 and interior casing 52 are formed with a cavity after the combination, the laminating is provided with a filter core cloth 53 in the cavity.

As shown in fig. 4, the inner housing 52 is detachably fixed on the sidewall of the housing 1 in an inserting manner, the end of the inner housing is integrally formed with a tightly-pressed protruding edge 521 which can be attached to the inner wall of the housing 1, a limiting portion 11 is disposed on the outer side of the housing 1, and when the inner housing 52 is pulled out from the inside of the housing 1, the outer wall of the inner housing can be attached to the limiting portion 11, so as to avoid the shaking. Certainly, the limiting portion can be made of plastic material alone and is disposed outside the box 1 in a locking and fixing manner, and the plastic material can reduce the noise generated during the insertion of the inner housing 52. The limiting part 11 is further sleeved with a sealing element 12, the sealing element 12 is used for preventing dust from flowing into the box body 1 from a gap between the limiting part 11 and the heat dissipation filter element 5, and the sealing element 12 can be made of an elastic material and is provided with an easy-to-detach notch 121 so as to be convenient to detach.

As shown in fig. 5, a plurality of filter cloth limiting strips 511 are integrally formed on the inner side of the outer shell 51, and after the outer shell 51 and the inner shell 52 are spliced with each other, the filter cloth limiting strips 511 can abut against the surface of the filter cloth to prevent the filter cloth from falling down and affecting the filtering effect.

Preferably, the outer housing 51, the inner housing 52, the stopper 11, and the seal member 12 are all circular. Of course, other shapes, such as square, triangular, etc., may be selected according to the actual situation.

In the middle of current cable branch box, its door body generally adopts key and tool to lock and locks, but if cable branch box installed in the eminence, this kind of mode of unblanking through the key is obviously too loaded down with trivial details, is not convenient for the constructor to operate. Therefore, in the present embodiment, the locking mechanism 4 includes a U-shaped locking block 41, a screw 42, a screw connecting shaft 43, a rotating shaft seat 44 and a hand wheel 45; the U-shaped locking block 41 is fixed on one side of the door body 3, the rotating shaft seat 44 is correspondingly fixed on the box body 1, the screw connecting shaft 43 is rotatably arranged on the rotating shaft seat 44, one end of the screw 42 is fixedly connected with the screw connecting shaft 43, the other end of the screw is in threaded connection with the hand wheel 45, and the hand wheel 45 can be mutually abutted with the U-shaped locking block 41 after being rotated, so that the door body 3 is locked on the box body 1. Of course, in order to reduce the friction between the hand wheel 45 and the U-shaped locking piece 41, a washer may be disposed on the hand wheel 45. Through this locking mode, the action of the door body can easily be opened to the one hand to the constructor, and need not to reuse tiny accessory of key this type, and is more convenient and fast when the eminence is operated, and the degree of safety is higher.

As another preferable anti-friction manner, in the locking mechanism 4 of the present design, a bearing 46 may be movably sleeved on the screw 42, and the spacers are disposed on two sides of the bearing 46, so that when the hand wheel 45 rotates to tightly push against the U-shaped locking block 41, the bearing 46 may be located between the U-shaped locking block 41 and the hand wheel 45, and when the hand wheel 45 needs to be screwed out, the bearing 46 may avoid a damping feeling generated by direct contact between the hand wheel 45 and the U-shaped locking block 41, and the hand wheel 45 may easily implement a rotation action (the bearing 46 belongs to an existing product, and is not described herein in detail).

Foretell heat dissipation filter core when the installation, insert to spacing portion in the middle of the interior casing of follow box with earlier, make the tight protruding edge in top and the tight laminating in inside top of box, then place the filter core cloth in interior casing again to fix with procapsid grafting, the sealing member is established to the cover at last, can accomplish the installation of heat dissipation filter core. When the pollution degree of the filter element cloth is higher, a constructor only needs to disassemble the front shell, and then the filter element cloth can be replaced.

When the inside high temperature of cable branch box, the inside radiator fan work of accessible circuit drive box, the outside flow of hot-air in the box is driven by radiator fan to reach the effect of cooling, in the middle of the process of circulation of air, filter core cloth can filter outside dust, avoids the dust to flow into the inside to cable branch box.
