Detailed Description

The present invention is specifically illustrated below by three examples:

example 1

As shown in fig. 1, the present invention relates to a dust guard, which comprises an outer plate 5, an inner plate 14, and a sandwiched flexible plate 12 disposed between the outer plate 5 and the inner plate 14. The sandwich ductile plate 12 is parallel to the outer plate 5 and the inner plate 14 such that the outer plate 5 and the sandwich ductile plate 12 form an outer gap 6 therebetween and the inner plate 14 and the sandwich ductile plate 12 form an inner gap 13 therebetween. The top of the inner side plate 14 is provided with mounting seats 16 that are distributed towards the outer side plate 5, and similarly, the bottom of the inner side plate 14 is also provided with mounting seats 16 that are distributed towards the outer side plate 5.

All seted up first slot 10 on the inner wall that is located the relative distribution of inner panel 14 top and bottom assembly seat 16, first slot 10 supplies sandwich toughness board 12 joint fixed fit, and sandwich toughness board 12 has the toughness of certain bending deformation to clamp sandwich toughness board 12 in first slot 10 between outer panel 5 and inner panel 14. After the upper end of the sandwich flexible panel 12 is clamped in the first slot 10 of the top assembly seat 16 of the inner side panel 14, a force is applied to bend the sandwich flexible panel 12 by a certain extent, and the lower end of the bent sandwich flexible panel 12 is clamped and fixed in the first slot 10 of the bottom assembly seat 16 of the inner side panel 14.

A second slot 8 is formed in the assembly seat 16 at the bottom of the inner side plate 14, a rib 7 is arranged at the lower end of the outer side plate 5, and the rib 7 and the second slot 8 are in clamping fit, so that the outer side plate 5 is stably clamped on the assembly seat 16 along the vertical direction, and the subsequent fixing of the upper end of the outer side plate 5 is facilitated. The left side surface of the assembly seat 16 positioned at the top of the inner side plate 14 and distributed towards the outer side plate 5 is provided with an L-shaped second positioning step 1, and correspondingly, the top of the outer side plate 5 is provided with an L-shaped first positioning step 3 attached to the second positioning step 1. And screws 2 are arranged on the outer side plate 5 and the assembly seat 16 at the aligned joint of the first positioning step 3 and the second positioning step 1, and the screws 2 are used for fixing the outer side plate 5 on the assembly seat 16.

The outer side plate 5 is provided with outer side vent holes 4 at even intervals, and the outer side vent holes 4 are straight holes. An inner side vent hole 15 which is distributed side by side with the outer side vent hole 4 is arranged on the inner side plate 14, and the inner side vent hole 15 is a straight hole. The sandwich toughness plate 12 is provided with communicating holes 11 which are respectively distributed with the outside vent holes 4 and the inside vent holes 15 in a staggered way, and the communicating holes 11 are straight holes. The outside ventilation hole 4, the communication hole 11 and the inside ventilation hole 15 are straight holes, so that sand dust indicated by arrows in fig. 1 directly impacts the sandwich flexible plate 12 after entering the sandwich flexible plate from the outside ventilation hole 4, the sandwich flexible plate 12 is bent and deformed under the impact force of the sand dust to block the inside ventilation hole 15, and the sand dust is prevented from penetrating into the inside ventilation hole 15.

Arc-shaped dust exhaust holes 9 are formed in the assembling seat 16 at the bottom of the inner side plate 14 from top to bottom, the dust exhaust holes 9 are communicated with the outer side gap 6 and are located between the first slot 10 and the second slot 8, so that sand and dust entering the outer side gap 6 from the outer side vent holes 4 can be settled under the blocking of the sandwich toughness plate 12 and can be discharged from the dust exhaust holes 9 through the outer side gap 6.

Example 2

The present embodiment is similar to embodiment 1 in overall structure, and the main difference is that: as shown in fig. 2, the outer vent hole 4 of the outer plate 5 is an inclined hole, the communication hole 11 of the sandwich flexible plate 12 is an inclined hole, and the inner communication hole 11 of the inner plate 14 is a straight hole corresponding to the inner vent hole 15 of example 1. The arrangement that the outside ventilation hole 4 and the communicating hole 11 are inclined holes can facilitate the sand and dust falling into the outside ventilation hole 4 and the communicating hole 11 to slide into the outside gap 6 and then be discharged from the dust discharging hole 9.

Example 3

The utility model relates to a dustproof block terminal, including adopting the left and right both sides board of the dust guard in embodiment 1 as the block terminal equipment, as the both sides board of dust guard respectively with the top panel of block terminal top, the bottom panel of block terminal bottommost, back panel and anterior panel mutual fixed connection.

The utility model discloses a concrete mode as follows: when the distribution box is in sand storm weather, wind and sand impact the outer side wall of the outer side plate 5 from the direction indicated by an arrow in fig. 1, part of the sand enters the outer side gap 6 through the outer side vent holes 4 and beats the sandwich flexible plate 12, and the sand subsides along the outer side gap 6 under the blocking of the sandwich flexible plate 12 and is discharged through the dust discharge holes 9. Meanwhile, the sandwich flexible panel 12 is deformed to bend toward the inner panel 14 under the impact of sand and dust, and the deformed sandwich flexible panel 12 closes the inner vent hole 15. After the inner side vent hole 15 is sealed, workers can rapidly detach the outer side plate 5 and the sandwich toughness 12 plate, so that dust in the outer side vent hole 4 and the communication hole 11 can be cleaned conveniently. Under the normal operating condition of block terminal, the heat of the inside production of block terminal passes through inside ventilation hole 15 and gets into in inboard clearance 13, and the heat gets into outside clearance 6 in passing through the intercommunicating pore 11 again, arranges to the block terminal outside through outside ventilation hole 4 at last, realizes the heat dissipation of block terminal.
