Abstract

The utility model relates to a traffic signal light box. The utility model is characterized in that the edge of the box cover is provided with an opening; the inner wall of the box is provided with a spring in the position which is corresponding with the opening of the box cover; the spring is bent toward the opening direction and extends out of the box through the opening; the part of the spring out of the box is bent toward the outer side of the box and is provided with a heave on the outer surface of the box cover. The utility model has the advantages that the utility model needs no tools to open and close the box cover, needs not to drill on the spring and the utility model has a simple structure.

Description

The traffic signals lamp box

Technical field

The utility model relates to the lamp box structure of traffic lights.

Background technology

The traffic lights case includes casing and case lid, and casing is used to install control circuit and signal lamp, and case lid has loophole, and signal light penetrates from loophole.In prior art, many between casing and the case lid with screw locking, so just necessary tool using ability opening and closing case lid, very inconvenience, and, therefore have more danger with instrument folding case lid at the scene because the installation and maintenance work of traffic lights belongs to work high above the ground.For this reason, ZL96222851.6 number, are called the utility model patent of " opening device of traffic lights case lid " and have done improvement, this patent locks case lid with spring leaf, overcome shortcoming with screw locking case lid, but because it is designed to the usefulness that double as is the pivot pin seat with spring leaf, have pin hole on spring leaf, therefore this syndeton is still simple inadequately.

Summary of the invention

The purpose of this utility model provides a kind of case lid and is easy to folding, and the simpler traffic signals lamp box of the syndeton between casing and the case lid.

The utility model is achieved in that the traffic lights case comprises casing and case lid, especially, edge at case lid has breach, position corresponding with the case lid breach on the inwall of casing is fixed with spring, spring is towards the direction elastic buckling of case lid breach, and extend out to outside the casing through the case lid breach, spring stretches out the outer part of casing towards the casing outside curve, and is provided with the projection that is contacting the case lid external surface.When covering case lid, as long as case lid is pushed on casing, the crooked position that makes the case lid edge bend towards the casing outside along the spring top slides, and spring is finally sprung in the breach at case lid edge, and the spring boss will contact the case lid external surface, thereby case lid is locked; When opening case lid, spring is stretched out the outer part of casing break off with the fingers and thumb, make the spring boss that originally contacts on case lid leave case lid, just case lid can be separated with casing towards the casing outside.This shows that the utility model not only is easy to the folding case lid, and owing to need not perforate on spring, so structure is simpler.

The utility model has the advantages that not only the case lid folding is easy, simple in structure, and, therefore can adopt spring wire to replace spring leaf, help reducing cost owing to need not perforate on spring.

Description of drawings

Below in conjunction with drawings and Examples the utility model is elaborated, wherein:

Fig. 1 is the structural representation of the traffic signals lamp box seen from the front;

Fig. 2 is the A portion enlarged drawing of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 2;

Fig. 4 is the right view of the whole spring among Fig. 3;

Fig. 5 is the left view of Fig. 4;

Fig. 6 is another embodiment of spring structure.

The specific embodiment

Referring to Fig. 1, the traffic lights case comprises casing 1 and case lid 2, and two drift angles of the case lid of present embodiment are hinged by jointed shaft 3 and casing 1, and two drift angles connect by spring in addition, can certainly be that four drift angles all adopt spring connecting structure.The spring connecting structure at each drift angle place is identical, with the A portion among Fig. 1 is example, referring to Fig. 2,3, have breach 4 at the edge of case lid 2, position corresponding with breach 4 on the inwall of casing 1 is fixed with spring leaf 5, and spring leaf 5 is towards the direction elastic buckling of case lid breach 4, and process case lid breach 4 extend out to outside the casing 1, referring to Fig. 4,5, spring leaf 5 stretches out the outer part of casing towards the casing outside curve, and is provided with the projection 6 that is contacting the case lid external surface simultaneously.When covering case lid, as long as case lid 2 is pushed on casing 1 as closing the door, the crooked position that makes the edge of case lid 2 bend towards the casing outside along the spring leaf top slides, spring leaf 5 is finally sprung in the breach 4 at case lid edge, and the boss 6 of spring leaf is contacting the external surface of case lid 2, form state shown in Figure 3, thereby with case lid 2 lockings; When opening case lid, break off with the fingers and thumb towards the casing outside as long as spring leaf is stretched out the outer part of casing, that is the left side in Fig. 3 breaks off with the fingers and thumb, make the spring boss 6 that originally contacts on case lid 2 leave case lid 2, just can remove the locking of 5 pairs of case lids 2 of spring leaf, so far case lid 2 can be opened.For the boss 6 that increases spring leaf the area that contacts with case lid 2, weigh the case lid external surface wounded with the boss 6 that prevents spring leaf, referring to Fig. 3, Fig. 5, present embodiment also is provided with flanging 7 at the boss of spring leaf 5.

Referring to another embodiment shown in Figure 6, this figure is represented, and to analyse and observe the position all identical with Fig. 3 with direction.Present embodiment replaces the spring leaf 5 of previous embodiment with spring wire 8, but the design feature of spring wire 8 is the same with spring leaf 5, that is all be direction elastic buckling towards case lid breach 4, and process case lid breach 4 extend out to outside the casing 1, and stretch out the outer part of casing, and also be provided with the projection 9 that is contacting the case lid external surface towards the casing outside curve.

Claims

1. traffic signals lamp box, comprise casing and case lid, it is characterized in that: the edge at case lid has breach, position corresponding with the case lid breach on the inwall of casing is fixed with spring, spring is towards the direction elastic buckling of case lid breach, and extend out to outside the casing through the case lid breach, spring stretches out the outer part of casing towards the casing outside curve, and is provided with the projection that is contacting the case lid external surface.

2. traffic signals lamp box as claimed in claim 1 is characterized in that described spring is a spring leaf, and is provided with flanging at the boss of spring leaf.
