Abstract
The utility model discloses a limit switch, comprising a housing. The housing comprises a pedestal and an upper cover. The pedestal is internally provided with an inner cavity, and the inner cavity is internally provided with a switch body. The switch body comprises a base. The base is detachably connected with the pedestal. The limit switch is advantaged in that when the switch body fails to work and needs to be overhauled, the switch body can be dismounted and overhauled, and if the switch body needs to be replaced, only the switch body is replaced instead of the whole limit switch.
Description
Technical field
The utility model belongs to the construction of switch design field, is specifically related to a kind of limit switch.
Background technology
Limit switch claims again travel switch, is a kind of little electric current master control electrical apparatus commonly used.Utilize the collision of manufacturing machine moving component to make its contact action realize connecting or the disjunction control circuit, reach certain control purpose.Usually, this class switch is used to position or the stroke of limit mechanical motion, make movable machinery by certain position or stroke automatically stop, counter motion, variable motion or automatic back and forth movement etc.In electric control system, the effect of limit switch is the detection that realizes sequential control, positioning control and location status, is used for stroke and the position limitation protection of control plant equipment.
The structure of common limit switch is in the market: comprise the housing that is provided with inner chamber and the Switch main body that is arranged in the described inner chamber; Described Switch main body has pedestal; Described housing is made of base and loam cake, and described base and loam cake adopt metal material to make; Described pedestal and described base are the integral type structure.The defective that the limit switch of said structure exists is: (1) because pedestal adopts integral structure with base, and when Switch main body breaks down when needing maintenance, the maintenance difficulty is large, in the time of maybe need changing, need to whole limit switch replacing, cause waste; (2) base and loam cake adopt metal material to make, and easily cause electric shock accidents, have potential safety hazard.
The utility model content
For the deficiency of pointing out in the background technology, the purpose of this utility model provides more reasonably limit switch of a kind of structure, use this limit switch, when Switch main body breaks down the needs maintenance, Switch main body can be pulled down maintenance, when changing such as need, only need to change Switch main body, and whole limit switch need not be changed.
The technical scheme that realizes the utility model purpose is:
A kind of limit switch comprises housing, and described housing is made of base and loam cake, is provided with inner chamber in the described base, is provided with Switch main body in the described inner chamber; Described Switch main body includes pedestal; Described pedestal is connected with described base is dismantled and assembled.
In the technique scheme, described pedestal and described base clamping or fix by screw.
In the technique scheme, an end and the described base of described loam cake are hinged, and the other end of described loam cake is connected with described base by screw.
In the technique scheme, described base is plastic feet, and described loam cake is upper plastic cover.
In the technique scheme, described base is provided with entrance hole, is provided with waterproof plug in the described entrance hole.
In the technique scheme, be provided with sealing ring between described base and the described loam cake.
The utlity model has positive effect: in the limit switch of the present utility model, because the pedestal of Switch main body is connected dismantled and assembled mode to connect with base, thereby when breaking down, Switch main body Switch main body can be pulled down maintenance, service work is convenient, when changing such as need, only need to change Switch main body and get final product, and need not change whole switch.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Reference numeral shown in the figure is: the 1-inner chamber; The 11-base; The 12-loam cake; The 13-entrance hole; The 14-waterproof plug; The 2-Switch main body; The 21-pedestal; The 3-sealing ring.
Embodiment
A kind of embodiment to limit switch of the present utility model elaborates below in conjunction with Figure of description:
As shown in Figure 1, a kind of limit switch comprises housing, and described housing is made of base 11 and loam cake 12, is provided with inner chamber 1 in the described base 11, is provided with Switch main body 2 in the described inner chamber 1; Described Switch main body 2 includes pedestal 21; Described pedestal 21 and described 11 dismantled and assembled connections of base.In the limit switch of the present utility model, because being connected with base, the pedestal 21 of Switch main body 2 adopt dismantled and assembled mode to connect, thereby when breaking down, Switch main body 2 Switch main body 2 can be pulled down maintenance, service work is convenient, when changing such as need, only need to change Switch main body 2 and get final product, and need not change whole switch.
Described pedestal 21 in the present embodiment is fixed with described base 11 clampings or by screw, and preferred version is clamping, need not increase screw and be fixed, and is fixedly connected with convenient.
One end and the described base 11 of the described loam cake 12 in the present embodiment are hinged, and the other end of described loam cake 12 is connected with described base 11 by screw, adopt this structure can prevent that loam cake 12 from losing after base 11 is pulled down, and easy accessibility.
Described base 11 in the present embodiment is plastic feet, and described loam cake 12 is upper plastic cover, thereby the insulation property of the housing that is made of base 11 and loam cake 12 are good, use safer.
Described base 11 in the present embodiment is provided with entrance hole 13, is provided with waterproof plug 14 in the described entrance hole 13, can improve the sealing property of product by waterproof plug 14 is set.
In order further to guarantee the sealing property of product, in the limit switch of present embodiment, also be provided with sealing ring 3 between described base 11 and the described loam cake 12.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
