Abstract

A distribution box face covering consists of a panel fixed to a distribution box, a door panel which is articulated with the panel and can make rotation movement around a hinge-axis compared with the panel, a locking mechanism arranged between the panel and the door panel. When the door panel starts rotating relative to the panel, the locking mechanism generates a friction between them, thus the door panel is locked under the opening state. The distribution box face covering has features of simple structure, reliable locking of the door panel and convenient operation.

Description

The distribution box cover

Technical field

The utility model relates to a kind of distribution box cover that has improved.

Background technology

The distribution box cover that uses is made up of panel and door closure usually at present, and panel is fixed on the distribution box, and door closure and panel are hinged, can rotate relative to panel.When electric component is operated in to distribution box, tilt-up door lid, and need to be fixed with hand steered door closure, this brings a lot of inconvenience to the operator.And existing can with on the distribution box cover of the door closure locking of turning over, has complicated locking mechanism more, and it is not firm to lock, and the temporary impact that door closure goes out of lock and produces when the position covers on the panel can cause damage to the electric component in distribution box cover, distribution box and the distribution box.

Summary of the invention

Main purpose of the present utility model provides a kind of simple in structure, distribution box cover that can the tilt-up door cover lock is fixed;

Another purpose of the present utility model provides the reliable and easy to operate distribution box cover of a kind of door closure locking.

To achieve these goals, the distribution box cover that the utility model provides comprises that is used for fixing the door closure that panel on distribution box is hinged with panel with, can rotate around hinge relative to panel, also has a locking mechanism, locking mechanism is arranged between door closure and panel, produce frictional force between the two at door closure when rotating relative to the panel unlatching, door closure is locked under opening.

The projection relative with groove on above-mentioned locking mechanism comprises the groove that is arranged on the door closure and is arranged at panel, it is on the circular arc in the center of circle that groove is positioned at the hinge.Projection locks door closure with making the frictional force that produces between panel and door closure cooperating of groove.

By such scheme as seen, this practical distribution box cover that provides, the frictional force of utilizing locking mechanism to make to produce between panel and door closure is with the locking of the door closure under the opening, and simple in structure, processing and assembling save production cost easily.

Further scheme is, the groove on the door closure is diminished gradually by origin or beginning to terminal groove depth, and door closure is in last process of turning over, and increasing by door closure and the frictional force between panel that locking mechanism produces, door closure locks more and more tightlyer.Like this, with the locking of tilt-up door lid be one by pine to tight progressive process, easy to operate, locking is reliably.

Further, the notch end on door closure is provided with a mortar, and when turning over to the extreme higher position on the door closure, the projection on the panel drops in the mortar, and mortar plays positioning action to projection, makes the locking of door closure more reliable.

The utility model is described in further detail below in conjunction with embodiment.

Embodiment

Referring to Fig. 1, the distribution box cover that the utility model provides comprises panel 1 and door closure 2, and panel 1 is used for fixing on distribution box.Panel 1 and door closure 2 are the left-right symmetric structure, and only the right side structure of counter plate 1 and door closure 2 explains below.

Fig. 2 is the right diagrammatic sketch of door closure 2, and Fig. 3 is the A partial enlarged drawing of Fig. 2; Fig. 4 is the back diagrammatic sketch of door closure 2, and Fig. 5 is the B partial enlarged drawing of Fig. 4.There is shown right side hinge 21, groove 22 and mortar 23 on the door closure 2.For clearly demonstrating the purpose of hinge 21 and mortar 23 structures, sightless hinge 21 and mortar 23 dot among Fig. 5.Referring to Fig. 3 and Fig. 5, hinge 21 is protruding from the side of door closure 2.Groove 22 is arranged on the side of door closure 2, and is positioned at hinge 21 rear, and groove 22 is for being the circular groove of center line to cut with scissors 21 axis, and the groove depth of groove reduces to end gradually from top.Mortar 23 is hemispherical, is arranged on the end of groove 22.

Referring to Fig. 6 and Fig. 7, the sidewall of panel 1 is provided with the fraising 11 that cooperates with hinge 21 on the door closure 2, and projection 12 internal faces from this sidewall inwardly stretch out, and projection 12 is substantially cylindrical, and its head is hemispherical, the parallel axes of axis and fraising 11.

Door closure 2 is installed to panel 1 time, with the fraising 11 that the hinge on the door closure 2 21 injects on the panels 1, it is hinged to be about to panel 1 and door closure 2, and door closure 2 can rotate relative to panel around the axis of fraising 11.The locking mechanism of distribution box cover comprises groove 22 on the door closure 2 and the projection 12 that cooperates with groove 22 on the panel 1.

Up stir door closure 2 to certain height, projection 12 falls into 22 li of grooves, continues tilt-up door lid 2, and projection 12 is in 22 li slips of groove.Because the groove depth of groove 22 reduces to end gradually from top, along with the angle of turning on the door closure 2 increases, the head of projection 12 contacts with groove 22 gradually, the frictional force that projection 12 and groove are 22 is also increasing, when frictional force during more than or equal to the gravity of door closure 2, thereby the moment of torsion that latter's countershaft produces will be less than or equal to the moment of torsion that the former countershaft produces, and door closure 2 just can be locked.From the beginning latched position, the angle of turning on the door closure 2 is big more, and door closure 2 is locked tightly more.When turning over to maximum angle on the door closure 2, projection 12 drops on 23 li in mortar.Mortar 23 cooperates with projection 12 head, positioning action is arranged to protruding 12, makes the locking of door closure 2 more comfortable, more reliable.At this moment, need not with hand steered door closure, the electric component in the distribution box that can be relieved is operated.When end of operation, door closure is closed with hand.

The foregoing description only is used for the understanding to the utility model design, be not to qualification of the present utility model, design can also have the simple change of many structures according to the utility model, for example, the groove of locking mechanism is arranged on the panel, and correspondingly, be arranged on the door closure with the projection of groove fit.
