It therefore is the key that whole system is well run with well contacting for travel switch.
Previous travel switch mount scheme is that the sliding block on handcart is directly contacted with travel switch, this requires travel switch
Have very high installation accuracy, if installation accuracy is not high enough, just will appear sliding block to travel switch do not reach position or excessively
The case where contact, and then influence whole work operation.
Utility model content
The purpose of the utility model is to provide a kind of travel switch boxes, to realize in debugging process, to travel switch
Contact become more smooth, stablize, the operation that operator can be more convenient is reduced and is led since travel switch installation is not in place
A possibility that causing maloperation.
To achieve the above object, the utility model provides the following technical solutions:
A kind of travel switch box, including travel switch bottom plate, travel switch cover board, baffle, sliding block, guide rail, travel switch
Tension spring and two travel switches；Described two travel switches are mounted on travel switch bottom plate, and the guide rail includes can be opposite
The the first guide rail branch and the second guide rail branch of sliding, first guide rail branch are mounted on travel switch bottom plate, are located at two
The lower section of a travel switch, the sliding block are fixed in the second guide rail branch, and the travel switch tension spring is fixed on travel switch
Between bottom plate and sliding block, the baffle is mounted on sliding block, and the travel switch cover board and travel switch base plate cover close.
According to the one aspect of the utility model, the travel switch bottom plate installation is on the cabinet.
According to the one aspect of the utility model, the top of the sliding block has convex portion, and the convex portion is located at
Between two travel switches, the convex portion can be contacted with one of two travel switches or not contacted.
According to the one aspect of the utility model, the baffle includes baffle main body and perpendicular to the baffle main body
Push plate.
According to the one aspect of the utility model, have and two travel switches and baffle on the travel switch cover board
The corresponding hollow hole in position, the push plate are stretched out from hollow hole.
By adopting the above scheme, the beneficial effects of the utility model are:
The travel switch box of the utility model efficiently avoids the high accuracy install requirement of previous mounting means, so that
In operating process, the contact with travel switch is no longer hard collision, but more smoothly while also extending stroke with stabilization
The wear life of switch.Allow operator that can clearly judge the status information and operation information of cabinet inner breaker, it is effective anti-
Stop due to maloperation and bring hidden danger, has substantially increased the safe and stable of power supply system.
Detailed description of the invention
Fig. 1 is the exploded view of the utility model travel switch box.
Fig. 2 is the mounted inside figure of the utility model travel switch box.
Fig. 3 is the left view after the utility model travel switch capsule.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, the travel switch box of the utility model, by travel switch bottom plate 1, travel switch cover board 2, baffle 3,
Sliding block 4, guide rail 5, travel switch tension spring 6 and two travel switches 7 form.
As shown in Figure 1, Figure 2 and Figure 3, two travel switches 7 are mounted on travel switch bottom plate 1, and height and position is consistent.It leads
Rail 5 includes the first guide rail branch and the second guide rail branch that can be slided relatively, wherein the first guide rail branch is mounted on travel switch
On bottom plate 1, positioned at the lower section of two travel switches 7, sliding block 4 is fixed in the second guide rail branch, and the top of sliding block 4 has protrusion
Part 8, the convex portion 8 are located between two travel switches 7, and the height and position of convex portion 8 need to meet it can be with two rows
Cheng Kaiguan 7 is contacted.Travel switch tension spring 6 is fixed between travel switch bottom plate 1 and sliding block 4, both ends respectively with travel switch bottom
Plate 1 and sliding block 4 connect.Baffle 3 is mounted on sliding block 4, including baffle main body and is located at baffle body side and perpendicular to gear
