Abstract

A traffic signal lamp shell includes a bottom shell (1) and an anterior cover (2). Four corners of the bottom shell (1) are respectively provided with a splinter (4); each splinter is bent to a flat part (41) and a bend part (42); corresponding four corners of the anterior corners (2) are respectively provided with an axle pin (3); the bend part (42) of the splinter (4) is opened with a hole (43) matching with the axle pin (3); four corners of the bottom shell (1) are respectively provided with a groove (11) for containing the splinter (4); each splinter (4) is respectively laid in each groove (11) of the bottom shell (1); when the anterior cover (2) is covered on the bottom shell (1), the axle pin (3) of four corners of the anterior cover (2) respectively goes through each axle pin hole (43). Compared with the prior art, the utility model has the following technical effects: open anterior cover and flexible locking; convenient installation and maintenance; long service life.

Description

The traffic signals lamp housing

Technical field the utility model relates to a kind of traffic lights, particularly relates to the opening device of traffic lights housing.

The opening device of traffic signals lamp housing generally is to adopt screw that protecgulum is fastened on the housing drain pan in the background technology prior art.The installation, maintenance of traffic lights need be unloaded whole protecgulum could work like this, and this is extremely inconvenient and is breakneck for work high above the ground.

The summary of the invention the technical problems to be solved in the utility model be to avoid above-mentioned the deficiencies in the prior art part and propose that a kind of traffic lights protecgulum is opened easily, installation and maintenance traffic signals lamp housing easily.

The technical problems to be solved in the utility model can be by solving by the following technical solutions:

Design, a kind of traffic signals lamp housing of use comprise drain pan, protecgulum and four shell fragments, and each shell fragment all is bent into straight portion and sweep; Four jiaos of described protecgulum are equipped with pivot pin, have the pin hole that matches with pivot pin on the sweep of described shell fragment, and described drain pan has the groove that holds described shell fragment for four jiaos; When described protecgulum and drain pan covered, described each shell fragment embedded respectively in each groove of described drain pan, and the pivot pin that described protecgulum is four jiaos passes through each pin hole respectively.

The utility model all adopts shell fragment as the pivot pin seat because of four angles, compares with prior art, has following technique effect: the traffic lights protecgulum is opened, is fastened flexibly; Installation, maintenance is convenient; Long service life.

The specific embodiment is described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.

A kind of traffic signals lamp housing as shown in Figure 1 and Figure 2, comprises drain pan 1, protecgulum 2 and four shell fragments 4, and each shell fragment all is bent into straight portion 41 and sweep 42; Four jiaos of described protecgulum 2 are equipped with pivot pin 3, have the pin hole 43 that matches with pivot pin 3 on the sweep 42 of described shell fragment 4, and described drain pan has the groove 11 that holds described shell fragment 4 for 1 four jiaos; When described protecgulum 2 covered with drain pan 1, described each shell fragment 4 embedded respectively in each groove 11 of described drain pan 1, and the pivot pin 3 that described protecgulum is 2 four jiaos passes through each pin hole 43 respectively.

As shown in Figure 3, when allowing protecgulum 2 fasten, the elastic force minimum of 4 pairs of drain pans 1 of described shell fragment, the sweep 42 of described shell fragment 4 is designed to the right angle bending with respect to straight portion 41.Sweep 42 owing to described shell fragment 4 is designed to the right angle bending with respect to straight portion 41 again, and protecgulum 2 described shell fragment 4 when buckling state does not deform, thereby shell fragment 4 is durable in use.

To shown in Figure 5,, be equipped with projection 45 up and down as Fig. 3 at the pin hole 43 of described shell fragment 4 for the pivot pin 3 of protecting protecgulum 2 is opened when fastening by described shell fragment 4 cuttings at protecgulum.

As shown in Figure 8, the end 46 of described each shell fragment 4 sweep 42 stretches out outside the described protecgulum 2, and wherein Yi Bian two shell fragment ends part of stretching out protecgulum is shorter than the part that on one side two shell fragments in addition stretch out protecgulum.When the maintenance traffic lights need be opened protecgulum 2, two long shell fragments of part that will stretch out protecgulum 2 unloaded, and as rotating shaft described protecgulum 2 are dug on one side with two shell fragments that the part of stretching out protecgulum 2 is short.
