Abstract

Laser leveler self-locking battery case, including box body, the left and right sides of box body are respectively equipped with guide groove, the limit protrusion that the box body bottom is equipped with along its length.The limit protrusion that the battery is equipped with is made of the plush copper of built-in spring and outer spring end.Water proof rubber bar is provided with the guide groove groove.The utility model is simple in structure, versatile, is easily assembled, and avoids battery and is fastened only by a battery cover, and battery connection is insecure, and circuit and shell are there are gap, the situation easily intake or made moist;And influence measurement result and the situation of construction effect.Battery case edge track slot structure nested with charging box uses the fabricated structure that convex-concave fastens, substantially increase the seal of control battery inside circuit, the supplying cell and control module for making level meter are in relatively closed environment, reduce the chance of control circuit board and air contact, the damage efficiency of control board is reduced, improves the service life of product.

Description

Laser leveler self-locking battery case
Technical field
The utility model is a kind of laser leveler self-locking battery case, belongs to laser level applied technical field.
Background technology
It is to determine horizontal line, horizontal plane in fields such as building, finishings, the survey horizontal tool used has board foot, plastic flexible pipe Linker, ordinary level, laser leveler etc., laser leveler are built due to having the advantages that measurement is accurate, rapid by large-scale Build and fitting-out work extensive use, but its is complicated, expensive, and be typically all use battery power, when measurement is regional When working environment is bad, such as:When misty rain, humidity or underwater operation, usually because control circuit is because humidity is by reasons such as oxidation short circuits It can not work normally, cause unnecessary construction delay, equally, in order to improve the cruising ability of portable level instrument, only lean on The lithium battery of machine itself can not meet to use, therefore just need to use external power supply unit, that is, external lithium electricity Pond, the thing followed are exactly how outside lithium battery realizes same environmental requirement.And often because battery capacity deficiency causes Battery is replaced at work, causes level meter position to change, and influences measurement result and construction effect.
The content of the invention
The utility model overcome the deficiencies in the prior art, the technical problem to be solved is that provide a kind of laser leveler to use Self-locking battery case, solves traditional power supply mode, avoids battery and is fastened only by a battery cover, battery and battery case It is directly connected to insecure, circuit and shell are there are gap, the situation easily intake or made moist.
A kind of laser leveler self-locking battery case, it is characterised in that the battery case includes box body, the left and right two of box body Side is respectively equipped with guide groove, the limit protrusion that the box body bottom is equipped with along its length.
Laser leveler self-locking battery case, it is characterised in that the limit protrusion that the battery is equipped with is by interior Put the plush copper composition of spring and outer spring end.
Laser leveler self-locking battery case, it is characterised in that be provided with water proof rubber in the guide groove groove Bar.
The utility model has an advantageous effect in that compared with prior art:It is simple in structure, it is versatile, it is easily assembled, Solve traditional power supply mode, avoid battery and fastened only by a battery cover, battery connection is insecure, circuit with it is outer Shell is there are gap, the situation easily intake or made moist;And influence measurement result and the situation of construction effect.The battery case edge Track slot structure nested with charging box uses the fabricated structure that convex-concave fastens, and substantially increases the close of control inside battery circuit Closing property, the supplying cell and control module for making level meter are in relatively closed environment, reduce control circuit board and air The chance of contact, reduces the damage efficiency of control board, improves the service life of product.
Brief description of the drawings

Fig. 2 is the stereogram of the utility model.
Fig. 3 is the use state diagram of the utility model.
Wherein, 1, charging box, 2, box body, 3, limit protrusion, 4, limit hole, 5, guide groove, 6, level meter, 7, fin.
Embodiment
As shown in Figure 1, 2, 3, a kind of laser leveler self-locking battery case, it is characterised in that the battery case includes one Box body 2, the left and right sides of the box body 2 are respectively equipped with guide groove 5 along its length, and 2 bottom of box body is additionally provided with limit protrusion 3。
Laser leveler self-locking battery case, it is characterised in that the limit protrusion 3 that the box body 2 is equipped be by The plush copper composition of built-in spring and outer spring end.
Laser leveler self-locking battery case, it is characterised in that be provided with waterproof rubber in 5 groove of guide groove Adhesive tape.
Embodiment
The box body 2 battery internal with it can use integral type enclosed construction, can also add box on box body 2 Lid, formed detachable structure, in order to replace the battery in battery case, in use, can according to the service condition of level meter 6, Delivery as required, by the box body 2 of the battery insertion battery case of different capabilities, forms independent battery box, avoids Steam enters.
The laser leveler of the utility model self-locking battery case, can be used cooperatively with charging box 1, described to fill such as Fig. 1 Electric 1 open at one end of box, for being inserted into this self-locking battery case, charging box(1)The left and right side of inner wall is equipped with two along 1 length of charging box Bar fin 7, the fin 7 is corresponding with the guide groove 5, and 1 bottom of charging box is equipped with and box body(2)On limit protrusion 3 limit holes 4 corresponded.Ensure battery case without departing from charging box 1 by the fastening of limit protrusion 3 and limit hole 4.
When charging for battery, it can both be charged by charging box 1 to the battery in this battery case, such as Fig. 1;Again can be with This battery case is installed in level meter 6 as shown in Figure 3 together with the battery in it, is charged by level meter 6 to battery.
