Abstract
The utility model discloses a limiting switch box which comprises a fixed box and a fixed box cover, wherein a plate is fixedly installed in the fixed box, a weight pendulum is obliquely and rotatably installed on the plate, two micro switch are installed, at the two sides of the weight pendulum, on the plate, and a sliding plate is arranged, between the two micro switches, on the plate. The limiting switch box is simple in structural design, equipment installation in the field is convenient, positioning is reliable, a limiting switch is installed inside the fixed box and thus has strong protective performance, the sensitivity of the limiting switch cannot be influenced by the change of the natural environment, and the limiting switch box adopts a modular form and has strong universality.
Description
Technical field
The utility model relates to mechanical device, is specifically related to a kind of limit switch box.
Background technology
According to market survey, after the cell panel price is tending towards rational state, need to improve to greatest extent the tracking means of solar power system efficient on the market.All need running part for single shaft, twin shaft, multi-shaft interlocked tracking support, it is that limit switch comes protective cradle that therefore every cover tracking support all needs position transducer, in order to avoid it is damaged.For in the market near switch, most job insecurity and install inconvenience, have a strong impact on install and cycle of debugging and switch almost all be exposed outside, be subject to the influence of external environment.
The utility model content
At the existing above-mentioned deficiency of existing limit switch technology, the utility model provides a kind of easy for installation, location reliably, not to be subject to the influence of natural environment and the limit switch box of highly versatile.
The technical scheme that the utility model adopts for achieving the above object is:
A kind of limit switch box, include fixed bin, fixing lid, it is characterized in that: be installed with a plate in the described fixed bin, described plate tilts and is rotatablely equipped with heavily pendulum, be positioned at and be separately installed with a sensitive switch on the plate of heavily putting both sides, on the plate between two sensitive switches, also be provided with a slide plate.
Described two sensitive switch balls are towards the inboard of plate.
Described heavy pendulum links together by double-screw bolt and plate, and double-screw bolt is screwed again.
Welding one slide plate on the plate between described two sensitive switches.
The upper right quarter of described plate is provided with a counterbore, and the top of described double-screw bolt just in time embeds wherein.
Described fixed bin is provided with four screwed holes, and described fixed bin covers and is provided with four corresponding with it through holes.
Operation principle of the present utility model:
This limit switch box is installed on the tracking support, and one can locate the tracking support, and two can protect tracking support and cell panel.It adopts gravity principle, utilizes heavily to put and touches sensitive switch, and what the sensitive switch here adopted is the normally closed type sensitive switch.Triggered a sensitive switch when heavily putting, this moment, sensitive switch can be left by normally closed often transferring to, meanwhile by light-coupled isolation signal is communicated to the I/O mouth of single-chip microcomputer, single-chip microcomputer is that signal of feedback makes the motor stop motion, makes corresponding response again according to real-time state then.
Advantage of the present utility model is:
(1) welds a slide plate by the relevant position between two sensitive switches, to the friction of plate, also can improve the tracking accuracy of limit switch when reducing heavily pendulum swing.
(2) be provided with a counterbore by the upper right quarter at plate, the top of double-screw bolt just in time embeds wherein, will heavily put with plate to be fixed up.
(3) be installed in various axle interlocks and follow the tracks of on the support, be used for controlling the elevating movement of support, guarantee that support meets the requirements of angle of pitch scope, prevent that support is damaged.
(4) the utility model structural design is simple, and is during erection unit, easy for installation at the scene, the location is reliable, and limit switch is mounted in the inside of fixed bin, and barrier propterty is strong, be not subjected to the change of natural environment and influence its sensitivity, what it adopted is modular form, highly versatile.

Embodiment
In an embodiment, referring to Fig. 1～Fig. 5, present embodiment provides a kind of reliable limit switch box, include fixed bin 1, fixedly lid 2, slide plate 3, plate 4, heavily put 5, double-screw bolt 6, sensitive switch 7, two sensitive switches 7 be fixed on the plate 4 by four 01 through holes on the plate 4 and fixedly the time two switches ball inwards, heavily put 5 and link together by double-screw bolt 6 and plate 4, double-screw bolt 6 is screwed again, and plate 4 is fixed on the fixed bin 1 by four 02 through holes on it.
A slide plate 3 is welded in the relevant position of two sensitive switches 7, to the friction of plate, also can improve the tracking accuracy of limit switch when reducing heavily pendulum swing.
The upper right quarter of plate 4 is provided with a counterbore, the top of double-screw bolt 6 just in time embeds wherein, realize heavily putting 5 with being connected of plate 4, fixed bin 1 is provided with four 03 through holes, be used for being installed in various axle interlocks and follow the tracks of support, be used for controlling the elevating movement of support, guarantee that support meets the requirements of angle of pitch scope, prevent that support is damaged.
Four 04 through holes establishing on four 04 screwed holes establishing on the fixed bin 1 and the fixing lid 2 are corresponding, and fixedly lid 2 is fixed on the fixed bin 1, fixes by the screw of four M4 * 10, and limit switch 7 is installed in 1 li of fixed bin, and barrier propterty is strong.
