Description

A kind of shot-light structure

Technical field

The utility model relates to the projecting lamp technical field, is specifically related to a kind of simple in structure, easy to assembly and be convenient to the shot-light holder structure of demolition and maintenance.

Background technology

Shot-light because its brightness height, handsome in appearance, style is fashionable is well received by consumers.Most on the market shot-light all is to change formula before the light source, and client uses very inconvenient, the lamp body front shroud must be unloaded during installation and maintenance, again light source is loaded onto or is unloaded, and the shot-light structure staff that has is difficult to stretch into to be installed light source or unload light source in the lamp body.So not only the consumer uses inconvenience, and dangerous.

Though change the formula structure after having few part shot-light to adopt light source at present on the market, all be knob type.This structure client uses also inconvenient, sprains power line easily, causes power line to get loose, and causes security incident.

The utility model content

Technical problem to be solved in the utility model provide easy installation and removal between a kind of bulb socket and the lamp body cover can after change light source a kind of shot-light structure.

For solving the problems of the technologies described above, the technical scheme that the utility model is realized is:

A kind of shot-light structure includes bulb socket and the lamp body cover that is connected with bulb socket, and the bulb socket sidewall is provided with lug, and lamp body cover inwall is provided with clamping or decontrols the resilient clamp device of lug.The bulb socket outer wall is provided with guiding rib, and lamp body cover inwall is provided with the gathering sill that cooperates with the bulb socket guiding rib, and lug is arranged on the bigger guiding rib of bulb socket, and the resilient clamp device is arranged at a gathering sill bottom in the lamp body cover.Clamper includes base and the sleeve body that is connected with base, is provided with clamping part, lead, rotor and return spring assembly in the inner space between sleeve body and the base.

The utility model has following remarkable result compared to existing technology:

Be connected by snap fit between the shot-light structure provided by the utility model, its bulb socket and lamp body cover, make to be easy to dismounting between bulb socket and the lamp body cover and to separate.When needing the installation or removal light source, push bulb socket, bulb socket leaves the lamp body cover, just can get off light source installation or removal from the spliced eye of bulb socket.The utility model shot-light changes the formula structure after adopting light source, and it is not only convenient but also fast and not sprain power line, safe and practical to use.

Description of drawings

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing;

Fig. 1 is the utility model surface structure schematic diagram;

Fig. 2 is a decomposing schematic representation of the present utility model;

Fig. 3 is the schematic appearance of clamper 3 among Fig. 2;

Fig. 4 is the decomposing schematic representation of Fig. 3 clamper.

The specific embodiment

Referring to Fig. 1～4, a kind of shot-light structure, include bulb socket 1, the guiding rib 11 of four protrusions is set on the bulb socket outer wall, have four gathering sills 21 that can cooperate on corresponding lamp body cover 2 inwalls with the bulb socket guiding rib, the bigger guiding rib that on the bulb socket is provided with is provided with lug 4, and lug is two.Corresponding is fixed with clamper 3 in bigger gathering sill bottom of lamp body cover.When the guiding rib of bulb socket when the gathering sill of lamp body cover slips in the lamp body cover, lug on the bulb socket is just in time aimed at clamper, and when pushing bulb socket repeatedly, the lug of bulb socket can be held device and clamp or loosen, thereby can make bulb socket arbitrarily leave the lamp body cover, the convenient installation changed light source.

Clamper includes base 36 and sleeve body 32, is respectively arranged with earhole on the outer wall of sleeve body and base, passes its earhole by screw 100 between sleeve body and the base both are fixed together.Clamping part 31, lead 33, rotor 34 and back-moving spring 35 are installed in the inner space between sleeve body and the base successively.Wherein the sleeve body inwall is evenly distributed with fin 321, and the lower end of fin is the inclined-plane.Lead is placed in the sleeve body, and convex tendon 331 is set on the lead outer wall, the groove interlock mutually that the fin of this convex tendon and sleeve lining forms.

Centre at lead also is provided with recess, be horizontally disposed with through hole 332 on recess two walls, the V-arrangement retaining part is in the recess of lead, described clamping part bottom also is provided with perforation 311, pin 200 passes the through hole of lead and the perforation of clamping part combines the two, can make clamping part along with lead slides up and down in sleeve body.

Simultaneously, the lead bottom also is connected with the column rotor by pin 300, makes clamping part, lead and rotor to move together.Be furnished with big spacing fin 341 on the described rotor outer wall, big spacing fin number is half of lead outer wall convex tendon, and also is the inclined-plane on the big spacing fin, and this inclined-plane is consistent with the direction on the inclined-plane of fin 321 lower ends of sleeve body inwall.The rotor upper end has the helical teeth snappable tooth set with the lead lower end.The rotor lower end contacts with the taper back-moving spring 35 that is fixed in base inside.

When bulb socket was placed on the lamp body cover, the tooth of the helical teeth of the lead lower end in the sleeve body and rotor upper end is mistake half just, and V-arrangement clamping part major part is exposed outside sleeve body, is connected with spring 312 between clamping part two folders refer to.When pushing bulb socket, lug on the bulb socket promotes clamping part and lead and slides along the groove of sleeve body inwall between clamping part two folder refers to, the just interlock of tooth of the helical teeth of the lead lower end in the sleeve body and rotor upper end, rotor moves down in the process of compression reseting spring and also rotates to an angle, push end, back-moving spring restores to the original state under the effect of elastic force, make that rotor is upwards passed, at this moment, the tooth of the helical teeth of the lead lower end in the sleeve body and rotor upper end is returned to wrong half position again, the inclined-plane of the big spacing fin upper end on the rotor outer wall, be involutory with the inclined-plane, lower end of sleeve body inwall fin 32, stop on the rotor and move, thereby the lug portion of being held is clamped firmly.

When pushing bulb socket once more, rotor can continue rotation, removes the prevention of sleeve body inwall to it, and rotor and lead move on together, finally make clamping part unclamp lug, and bulb socket leaves the lamp body cover.

The utility model installation and maintenance light source is convenient, safety.Click the bulb socket end face with light finger when needing light source is installed, promptly hear the sound of " click ", bulb socket is held device immediately and ejects a height, with hand bulb socket is taken out, load onto light source the light source spliced eye in the middle of bulb socket, be on the bulb socket among four guiding ribs with bulb socket by direction again, a gathering sill of broad in four gathering sills on the guiding rib rough alignment lamp body cover of broad is wherein put into the lamp body cover, make lug aim at the clamping part of clamper just, flicking is bulb socket once, promptly hear the sound of " click ", lug is held device when clamping, and bulb socket also is fixed in the lamp body cover thereupon.
