Description

Power supply box Simple lock catch structure

Technical field

The utility model relates to a kind of buckle structure, is specifically related to a kind of power supply box Simple lock catch structure.

Background technology

Along with the progress of society, increasing electric equipment is widely used in people's living environment, and for these electric equipments, its common feature is all need to be driven by electric power.Electric power energy is as a kind of Power supply mode, and it has lot of advantages, but must utilize corresponding power transmission lines just can realize the supply of electric power.So using people must be by corresponding power transmission lines in the process of electric equipment, and must need auxiliary with corresponding pressure regulation, branch means in the power transmission lines transferring electric power, so that main power transmission lines can produce branch road in specific place again, use for different rooms or user.With regard to this electric power transfer application mode, all need to one power supply box be set to hold relevant circuit, transformer and other relevant power components in open air, specific room in concrete enforcement.

How a kind of buckle structure that matches with the outdoor power system case being provided, on the one hand guaranteeing the closely sealed of power supply box, guarantee that on the other hand power supply box can easily and timely open, is also a problem demanding prompt solution.Have in the market a kind of buckle structure, comprise catching groove, holder, active connection, movable lock ring, be provided with through hole on active connection, movable lock ring need to be tipped through hole and hinged with active connection after treatment in, active connection is hinged with holder again, its assembling and complex installation process, operation is trouble very, and cost of production is relatively high.

The utility model content

For the deficiency that prior art exists, the utility model provides a kind of power supply box Simple lock catch structure, and this power supply box Simple lock catch structure easily installs, simple in structure, reduces production costs.

For achieving the above object, the utility model provides following technical scheme: a kind of power supply box Simple lock catch structure, comprise casing drain pan and box cover, described box cover is fixedly installed catching groove, be provided with holder on described casing drain pan, be provided with on described holder by the hinged active connection of rotating shaft, described active connection is connected with catching groove by movable lock ring, described active connection is one-body molded, be provided with groove on active connection, described movable lock ring directly embeds described groove.

By adopting technique scheme, active connection is one-body molded, do not need hinged with movable lock ring and process, movable lock ring can directly embed in groove on active connection, reach locking effect by the active lock latch closure on the catching groove of box cover again, easily installation, simple in structure, reduce production costs.

The utility model further is set to, and described holder bottom is fixedly connected with the casing drain pan, and the holder two bottom sides is extended raised line.

By adopting technique scheme, raised line has been strengthened the bonding strength of holder and casing drain pan, can be in holder bottom be issued to better bonding strength with the less situation of casing drain pan contact surface, prevent from stressedly spending being connected of havoc holder and casing drain pan.

The utility model further is set to, and the described active connection back side and holder are inconsistent, and described holder and raised line form a resistance surface, and the shape at the shape of described resistance surface and the active connection back side is suitable.

By adopting technique scheme, when buckle structure is in locking state, active connection and catching groove produce a pulling force by movable lock ring and reach locking effect, the shape at the shape of resistance surface and the active connection back side is suitable, resistance surface is just inconsistent with the active connection back side when locking state, prevents the excessive excessive damage lock buckle structure of pulling force that causes of active connection rotation.

The specific embodiment

Referring to figs. 1 through Fig. 3, the utility model power supply box Simple lock catch structure embodiment is described further.

A kind of power supply box Simple lock catch structure, comprise casing drain pan 10 and box cover 1, box cover 1 is fixedly installed catching groove 2, be provided with holder 3 on casing drain pan 10, be provided with on holder 3 by the hinged active connection 5 of rotating shaft 4, active connection 5 is connected with catching groove 2 by movable lock ring 6, and active connection 5 is one-body molded, be provided with groove 7 on active connection 5, movable lock ring 6 directly embeds groove 7.

By adopting technique scheme, active connection 5 is one-body molded, do not need hinged with movable lock ring 6 and process, movable lock ring 6 can directly embed in groove 7 on active connection 5, be buckled on the catching groove 2 of box cover 1 by movable lock ring 6 again and reach locking effect, easily installation, simple in structure, reduce production costs.

Described holder 3 bottoms are fixedly connected with casing drain pan 10, and holder 3 two bottom sides are extended raised line 8.

By adopting technique scheme, raised line 8 has been strengthened the bonding strength of holder 3 with casing drain pan 10, can be issued to better bonding strength in holder 3 bottoms and the less situation of casing drain pan 10 contact surfaces, prevent from stressedly spending being connected of havoc holder 3 and casing drain pan 10.

Described active connection 5 back sides and holder 3 are inconsistent, and holder 3 forms resistance surfaces 9 with raised line 8, and the shape at the shape of resistance surface 9 and active connection 5 back sides is suitable.

By adopting technique scheme, when buckle structure is in locking state, active connection 5 produces a pulling force with catching groove 2 by movable lock ring 6 and reaches locking effect, the shape at the shape of resistance surface 9 and active connection 5 back sides is suitable, resistance surface 9 is just inconsistent with active connection 5 back sides when locking state, prevents the active connection 5 excessive excessive damage lock buckle structures of pulling force that cause of rotation.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model also not only is confined to above-described embodiment, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art, in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
