Abstract

The utility model relates to a convenient battery box. The utility model comprises an outer shell, an inner core and a locking device, wherein, the locking device is composed of a mounting buckle arranged on the outer shell, a clamping hook and a torsion spring, and the clamping hook is movably sheathed on the mounting buckle via a pin shaft. The torsion spring is arranged between the outer shell and the clamping hook via the pin shaft, the shell body of the inner core is provided with a corresponding clamping position corresponding to the hook head of the clamping hook, and the inner core is inserted in the inner chamber of the outer shell and clamped in the outer shell via the locking device. Due to the adoption of a double-layer box body structure with the locking device and a release device, the utility model can fully ensure that the batteries can be taken out and put in conveniently and simply in the process of replacement.

Description

A kind of battery case that makes things convenient for

The utility model relates to a kind of full-automatic gas-fired water heater battery case, belongs to the improvement of household electrical appliance.

At present, the battery case that matches with full-automatic gas-fired water heater mainly is made up of box body and the enclosing cover of band both positive and negative polarity conducting strip on the market, is installed in bottom the water heater, and under normal circumstances people's vision is difficult to see clearly its concrete position.Finish by the elasticity that overcomes positive/negative plate when taking, and can only hold one or two finger and operate, bring great inconvenience and trouble for like this replacing battery, its appearance and modeling is quite coarse, not attractive in appearance.

The purpose of this utility model provides and a kind ofly changes conveniently, easily, the full-automatic gas-fired water heater of simple, good looking appearance is with making things convenient for battery case.

The utility model comprises shell, inner core and locking device, wherein locking device installing tache, grab and torsion spring on the shell formed by being located at, grab by the bearing pin movable set on installing tache, torsion spring is arranged between shell and the grab by bearing pin, the one end withstands side wall of outer shell, the other end withstands the grab back, the corresponding grab gib head of inner core housing position is provided with corresponding screens, and inner core is inserted into shell inner cavity and tightens in the enclosure by locking device.

Corresponding grab tail position is provided with releasing device on the above-mentioned shell, and this releasing device is made up of mount pad, knob, a bar and back-moving spring, and back-moving spring is sleeved on the push rod, and the push rod top is connected with button, and its bottom contacts with the grab afterbody.

The utility model is because employing has the double-layer box structure of locking device and releasing device, battery can be inserted in the inner core outside machine very easily, and easily push in the shell and tighten, and when taking out, only need one to press gently, promptly can automatically inner core be ejected from overcoat by the elastic device in the shell, fully guarantee to change the convenience of cell process with light, simple, the structure that is nested inside and outside simultaneously this, its outward appearance can be made and have fairshaped style beautiful, attractive in appearance, reach the purpose of this utility model.

Describe basic structure of the present utility model and basic principle in detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model inner core;

Fig. 3 is that the P of Fig. 1 is to view;

Fig. 4 is that the M of Fig. 2 is to view.

As Fig. 1-shown in Figure 4, the utility model comprises shell (1), inner core (2), locking device (3) and releasing device (4), wherein locking device (3) is made up of the installing tache (31), grab (32) and the torsion spring (33) that are located on the shell (1), grab (32) is movably arranged on the installing tache (31) by bearing pin, torsion spring (33) is arranged between shell (1) and the grab (32) by bearing pin, the one end withstands shell (1) sidewall, and the other end withstands grab (32) back.The corresponding grab (32) of inner core (2) housing gib head position is provided with corresponding screens (21), this screens (21) can be arranged on protrusion fixture blocks such as the triangle boss on inner core (2) sidewall, also can be arranged on depression bayonet sockets such as breach on inner core (2) sidewall, inner core (2) be inserted in the shell (1) and the grab (32) by locking device (3) be clamped in the shell (1) the cooperating of screens (21) of inner core (2).Releasing device (4) is arranged on shell (1) and goes up corresponding grab (32) tail position place, this releasing device (4) is made up of mount pad (41), button (42), push rod (43) and back-moving spring (44), back-moving spring (44) is sleeved on the push rod (43), push rod (43) top is connected with button (42), its bottom contacts with grab (32) afterbody, push rod (43) front portion is provided with spacer, to guarantee that push rod (43) is fixed on mount pad (41) and upward can break away from mount pad (41).For guarantee that inner core (2) can eject easily from shell (1), be provided with rebound spring (11) in the shell (1), rebound spring (11) is arranged between the positive/negative plate of shell (1) bottom, for making things convenient in inner core (2) the turnover shell (1), corresponding inner core (2) screens (21) position is provided with breach (12) between shell (1) top installing tache (31).For guaranteeing the good of electric conductivity between inner core (2) and the shell (1), inner core (2) base plate is provided with the conducting strip (22) of positive and negative electrode outward, and the positive and negative plate of conducting strip (22) bottom shell (1) is corresponding.

Basic functional principle of the present utility model is: when need are packed into, inner core (2) plug-in mounting that battery is housed is advanced shell (1) inner chamber, the screens (21) of inner core (2) tightens with the grab (32) that shell (1) is gone up locking device (3), simultaneously, the conducting strip (22) of inner core (2) is connected with the positive/negative plate of shell (1), forms a complete battery case; When need take out, only need press the button (42) of releasing device (4) gently, push rod (43) backs down grab (32), grab (32) and screens (21) are broken away from, under the elastic force effect of rebound spring (11) and shell (1) positive/negative plate, the screens (21) of inner core (2) is withdrawed from along the breach (13) on the shell (1), and whole inner core (2) is ejected from shell (1) inner chamber, reaches the purpose of taking out battery.
