The fixed structure of optoelectronic switch
Technical field
The utility model relates to a kind of optoelectronic switch, particularly mainly is applicable to the fixed structure of the optoelectronic switch that evaporation type cooling fan uses.
Background technology
At present, evaporation type cooling fan is unique because of its outward appearance, and exportable cold wind and warm braw, and the characteristics such as noise is little in the use procedure more and more are subject to consumer's favor.Safe handling and the maintenance of evaporation type cooling fan in order to guarantee product commonly used mostly arranges the power-off protection apparatus that is comprised of optoelectronic switch or dry-reed tube switch in product.After opening fan drum and taking off filter assemblies, optoelectronic switch or dry-reed tube switch can play the effect of control complete machine outage, to realize the power-off protection function of complete machine.But the optoelectronic switch of existing evaporation type cooling fan and its support adopt screw mostly or the mode of playing glue fixes, and these two kinds of fixed forms are complex steps, operating difficulties not only, and easily damage optoelectronic switch and support thereof in fixation procedure is installed.Therefore, be necessary to make further improvements.
The utility model content
The purpose of this utility model aim to provide a kind of simple in structure, install conveniently, be used for the fixedly optoelectronic switch fixed structure of evaporation type cooling fan, to overcome the deficiencies in the prior art part.
Press the fixed structure of a kind of optoelectronic switch of this purpose design, comprise optoelectronic switch and support thereof, its architectural feature is that described support is provided with the empty avoiding breach, and the empty avoiding indentation, there is provided with fixed mechanism, optoelectronic switch snaps in the empty avoiding indentation, there, and cooperates directly with fixed mechanism and to be fixed on the support.
Described fixed mechanism comprises limit sliding chutes and elastic fastening hook, and limit sliding chutes is arranged on the top of the empty avoiding breach of ㄇ shape, and the bottom of elastic fastening hook is fixed on the horizontal edge middle part of the empty avoiding breach of ㄇ shape.
Described limit sliding chutes is arc, and the vertical edge of empty avoiding breach and horizontal edge consist of the cell wall of limit sliding chutes one side.
The lateral surface of described elastic fastening hook hook portion is wedge shape.
The base of described optoelectronic switch snaps in the empty avoiding breach along the conduit of limit sliding chutes, and a side of base props up the bottom of limit sliding chutes, and opposite side and elastic fastening hook are fixed.
The utility model has the empty avoiding breach at the support of optoelectronic switch, and in the empty avoiding indentation, there limit sliding chutes and elastic fastening hook is set.By optoelectronic switch is slipped into the empty avoiding breach along limit sliding chutes, and the hook portion of elastic fastening hook is matched with the base of optoelectronic switch, thereby optoelectronic switch and support are fixed.Need not to use screw or play glue, greatly saved installation time, improved efficiency of assembling.
The utlity model has simple in structure, easy to assembly, dependable performance, the characteristics such as applied widely.
Description of drawings
Fig. 1 is the utility model one embodiment decomposition texture schematic diagram.
Fig. 2 is an example structure schematic diagram.
Among the figure: 1 is support, and 2 is optoelectronic switch, and 2.1 is base plate, and 3 are the empty avoiding breach, and 3.1 is horizontal edge, and 3.2 is vertical edge, and 3.3 is elastic fastening hook, and 4 is limit sliding chutes.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 2, a kind of fixed structure of optoelectronic switch comprises optoelectronic switch 2 and support 1 thereof.Have the empty avoiding breach 3 of ㄇ shape on the support, the top of empty avoiding breach is provided with limit sliding chutes 4.Limit sliding chutes is arc, and it is symmetricly set on the top of 3 liang of vertical edges 3.2 of empty avoiding breach, and the cell wall of the horizontal edge 3.1 of empty avoiding breach and vertical edge 3.2 formation limit sliding chutes 4 one sides.Middle part at empty avoiding breach horizontal edge 3.1 is provided with elastic fastening hook 3.3, and the bottom of elastic fastening hook is fixed on the horizontal edge 3.1, and the lateral surface of grab hook portion is wedge shape.
When mounted, the base 2.1 of optoelectronic switch 2 conduit along limit sliding chutes 4 is slipped in the support; In this process, base 2.1 moves down elastic fastening hook to the hook portion of lower compression elastic fastening hook 3.3.When a side of base 2.1 propped up the bottom land of limit sliding chutes 4, elastic fastening hook 3.3 resetted; Elastic fastening hook cooperates with the opposite side of base, and optoelectronic switch is fixed in the support 1.
This technical scheme also is applicable to fan, warmer, the optoelectronic switch of tower fan product or the fixing of dry-reed tube switch of similar structures.
