Abstract

The utility model relates to a distribution housing cover which comprises a board with a recess and a board gate which covers the recess. Wherein, the board gate is flexibly hinged with a board via, an articulated axle and an articulated bore. A raised elastic element which is fitted with the hinge edge between the board gate and the two articulated axles or articulated bores is arranged in the recess between the board and the two articulated bores or articulated axles. The utility model provides a distribution housing cover which is independent from the friction force as a result of squeezing of two parts and will not fall down when the board gate is opened.

Description

A kind of Distribution box cover

Technical field

The utility model relates to a kind of Distribution box cover.

Background technology

Existing Distribution box cover, panel door jointed shaft and panel hinge hole are movably hinged, when panel door is upwards opened, on the one hand, rely on the hinged edge between panel door two jointed shafts and the friction of the recess between panel two hinge holes, panel door is opened after, can not fall automatically, on the other hand, rely on the jointed shaft of making ellipse to rotate to the major axis position, make and form friction between jointed shaft and the hinge hole, after panel door is opened, can not fall automatically, above-mentioned two aspects all are to rely on external force, make the extruding of two parts form frictional force, this mode, wearing and tearing are big, damage parts easily, after using a period of time, because wearing and tearing after panel door is opened, fall very easily automatically.

Summary of the invention

The purpose of this utility model is exactly to propose a kind of frictional force that does not rely on the extruding of two parts to form, panel door is opened after, the Distribution box cover that can fall automatically not.

For achieving the above object, a kind of Distribution box cover, comprise panel that is provided with recess and the panel door that covers on recess, panel door is movably hinged by jointed shaft, hinge hole and panel, panel two hinge holes, or jointed shaft, between recess be provided with the projection elastic component, this elastic component and panel door two jointed shafts, or hinge hole, between hinged edge cooperate.

Can be at two hinge holes of panel recess, or jointed shaft, between offer hollow slots, the hollow slots two ends are positioned at the same side, the part that described elastic component is surrounded by hollow slots constitutes, constitute the root of elastic component between the hollow slots two ends, the end that root is relative constitutes the top of elastic component, and the top is provided with the projection of protruding recess surface.

The top of described elastic component, root can be successively along the rotation direction settings of panel door hinged edge, and the shape of described elastic component can be a strip.

The projection of described elastic component can be made as the lug of opening direction towards panel door gently, is made as precipitous towards the close lug of direction of panel door.

Described elastic component can be provided with two.

Because the utility model is provided with the elastic component of projection, when panel door is opened, the panel door hinged edge is through the projection of this elastic component, under elastic reaction, the boss of elastic component moves, and panel door is passed through, then, resetting fastens the panel door hinged edge, makes panel door stay open state, can not fall automatically.

Embodiment

As shown in Figure 1, be in the scheme of installation of open mode for the panel door 2 of the utility model embodiment.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of Distribution box cover of the utility model embodiment, be provided with the panel 1 and the panel door 2 that covers on recess 11 of recess 11, panel door 2 jointed shafts 21 and panel 1 hinge hole 12 are movably hinged, as shown in Figure 2, recess 11 between 1 liang of hinge hole 12 of panel is provided with the elastic component 13 of two projectioies 133, this elastic component 13 is the recesses 11 between 1 liang of hinge hole 12 of panel, offer hollow slots 14, hollow slots 14 two ends are positioned at the same side, the part of being surrounded by hollow slots 14 constitutes, constitute the root 131 of elastic component 13 between hollow slots 14 two ends, root 131 relative ends constitute the top 132 of elastic component 13, the top 132 of elastic component 13, root 131, successively when panel door 2 is opened, the direction setting that its hinged edge 22 rotates, the shape of elastic component 13 is strips, as shown in Figure 3, the top 132 of elastic component 13 is provided with the projection 133 of protruding recess 11 surfaces, this projection 133, the lug 1331 of opening direction towards panel door 2 is made as gently, is made as precipitously towards the close lug 1332 of direction of panel door, and the hinged edge 22 between 2 liang of jointed shafts 21 of elastic component 13 and panel door cooperates.

The jointed shaft 21 of panel door 2 inserts the hinge hole 12 of panel 1, when panel door 2 is upwards opened, the hinged edge 22 of panel door 2 is through the projection 133 at strip elastic component 13 tops 132, under elastic reaction, move at the top 132 of elastic component 13, panel door 2 hinged edges 22 are by after the projection 133 at elastic component 13 tops 132, elastic component 13 tops 132 reset, rely on the projection 133 at top 132, fasten the hinged edge 22 of panel door 2, make panel door 2 remain open mode, can not fall automatically, when needs close panel door 2, only need panel door 2 is exerted oneself a little downwards, move at the top 132 of elastic component 13, and panel door 2 hinged edges 22 are passed through, and panel door 2 closes immediately.

The jointed shaft 21 of panel door 2 makes hinge hole into, and corresponding therewith, the hinge hole 12 of panel 1 makes jointed shaft into, and mechanism is the same.
