Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

In a first embodiment, referring to fig. 1-2, a fastener includes a case 1, a movable member 2, a spring 3, a snap ring 4, and a key cap 5. The lateral wall of 1 bottom of box body is equipped with first through-hole 11 and second through-hole 12 respectively, is equipped with third through-hole 13 and fourth through-hole 14 on the lateral wall at 1 top of box body, and first through-hole 11 and third through-hole 13, second through-hole 12 and fourth through-hole 14 align, and 1 front portion of box body opens in order to form spring mounting mouth 15, and the lateral wall of the 1 left and right sides of box body all is equipped with installation screw 16.

The movable member 2 includes a first support arm 21, a second support arm 22 and a connecting section 23, and first ends of the first support arm 21 and the second support arm 22 are connected and fixed by the connecting section 23, so that the movable member 2 is U-shaped. The second end of the second support arm 22 is inserted through the second through hole 12 and extends out of the fourth through hole 14, and the second end of the first support arm 21 is inserted through the first through hole 11 and extends out of the third through hole 13 and then is fixedly connected with the key cap 5, so that the box body 1 is simultaneously sleeved on the first support arm 21 and the second support arm 22.

The spring 3 is arranged in the box body 1 from the spring mounting opening 15, and the first support arm 21 also passes through the spring 3 when passing through the box body 1, so that the spring 3 is sleeved on the first support arm 21. The position of the first support arm 21 in the box body 1 is provided with a clamping groove 24, the clamping ring 4 is clamped into the clamping groove 24 through the spring mounting hole 15, one end of the spring 3 is abutted against the clamping ring 4, and the other end of the spring 3 is abutted against the box body 1. Preferably, box body 1, moving part 2, spring 3, snap ring 4 and button cap 5 are made by the metal, improve fastener overall structure intensity.

Under normal conditions, the elastic force of the spring 3 makes the snap ring 4 abut against the box body 1, so that the second end of the second support arm 22 extends out of the box body 1, i.e. the second end of the second support arm 22 is used as a plug pin part of the fastener. According to the button cap 5, the moving part 2 moves integrally, when the moving part 2 moves, the spring 3 is compressed through the snap ring 4, so that the second end part of the second support arm 22 moves towards the box body 1, namely, the second end part of the second support arm 22 extends out of the inner part of the box body 1 and becomes short. When the key cap 5 is released, the elastic force of the spring 3 pushes the movable member 2 to return, i.e. the second end of the second support arm 22 extends out of the case 1 again. The whole fastener can be manufactured alone and assembled into the range hood, and the fastener is in modular design, so that the production cost is reduced.

Referring to fig. 3-5, a range hood comprises a shell 6, a rectifying plate 7 and the fastener, wherein a support 8 is arranged on the back of the rectifying plate 7. Specifically, cowling panel 7 is made for a monoblock toughened glass, and support 8 passes through the silica gel viscose to be fixed in cowling panel 7. In order to stably fix the rectifying plate 7, brackets 8 are arranged on the left side and the right side of the rectifying plate 7. The mounting screw hole 16 on the box body 1 of the fastener is fixedly connected with the front end of the bracket 8 through a screw, so that the key cap 5 of the fastener is arranged towards the front end of the shell 6, and the second support arm 22 is positioned above the first support arm 21. The rear end of the bracket 8 extends out of a hook 81, and the hook 81 and the rear end of the bracket 8 form a T-shaped slot 82.

The shell 6 is provided with a first fixing position 61 corresponding to the front end of the bracket 8 and a second fixing position 62 corresponding to the rear end of the bracket 8. First fixed position 61 is including preceding spacing baffle 9, and preceding spacing baffle 9 bottom still is equipped with oblique deflector 91, is equipped with jack 92 on the preceding spacing baffle 9. The second holding station 62 comprises a capped pin 10.

The rear end of the bracket 8 is first seated on the pin 10, so that the pin 10 is disposed in the T-shaped slot 82, i.e., the rear end of the bracket 8 and the second fixing portion 62 form a detachable connection. The rectifying plate 7 is moved backwards, the pin 10 abuts against the front end of the T-shaped groove 82, the support 8 cannot move up and down relative to the pin 10, at this time, the front end of the rectifying plate 7 is moved upwards, namely the fastener at the front end of the support 8 is close to the first fixing position 61 until the fastener moves to the inclined guide plate 91, the second end of the second support arm 22 abuts against the inclined guide plate 91, the front end of the rectifying plate 7 is moved continuously, the inclined guide plate 91 guides the second end of the second support arm 22 to retract into the box body 1, so that the fastener moves to the rear of the front limit baffle 9, the second end of the second support arm 22 abuts against the front limit baffle 9, when the second end of the second support arm 22 aligns with the insertion hole 92, the second end of the second support arm 22 is inserted into the insertion hole 92 by the elastic force of the spring 3, and the fixing of the rectifying plate 7 is completed.

When the key cap 5 is pressed down, the second end of the second support arm 22 is separated from the jack 92, the front end of the rectifying plate 7 moves to drive the support 8 to slide downwards forwards, the T-shaped groove 82 moves to enable the pin 10 to be arranged at the rear end of the T-shaped groove 82, namely the hook portion 81 is hooked with the pin 10, the rectifying plate 7 rotates around the pin 10, and therefore the rectifying plate 7 is hung, and therefore the rectifying plate 7 cannot generate danger due to the fact that the shell 6 is removed at one time. The rectifying plate 7 is moved upward to separate the hook 81 from the pin 10, and the rectifying plate 7 can be removed.
