Detailed Description
As shown in fig. 1 to 3, an embodiment of the present utility model provides a modular terminal assembly capable of positioning a cover plate, which includes a case 1, a cover plate 2, and a supporting member 3.
The front end face of the box body 1 is sunken with a control groove 11, and the rear end face of the control groove 11 is provided with a strip-shaped hole for exposing terminal appliances such as a switch, a circuit breaker, a fuse, an overvoltage protector, a leakage protector and the like.
The cover plate 2 is covered at the front end opening of the control groove 11, and the upper ends of the left side and the right side of the cover plate are respectively and rotatably connected with the upper ends of the left side and the right side of the control groove 11.
At least one of the left side and the right side of the control groove 11 is provided with a sliding groove 12, the supporting piece 3 and the sliding groove 12 are positioned on the same side, the upper end of the supporting piece is rotationally connected with the side edge of the cover plate 2 on the same side, and the lower end of the supporting piece slides in the sliding groove 12.
Specifically, the upper end of the supporting member 3 is close to the upper edge of the cover plate 2, and preferably, the distance between the upper end of the supporting member 3 and the upper edge of the cover plate 2 is smaller than one quarter of the side length of the cover plate 2 on one side thereof, so that the cover plate 2 can be supported at a sufficiently large angle without being obstructed for a user.
In this embodiment, the whole support member 3 is approximately zigzag, the upper end of the support member is bent toward the side of the cover plate 2 to form a connecting column 31, the side of the cover plate 2 is provided with a jack, and the connecting column 31 is inserted into the jack to be rotatably connected with the cover plate 2.
The lower end of the support 3 is bent toward the sliding groove 12 with a sliding column 32, and the sliding column 32 is inserted into the sliding groove 12 and moves in the sliding groove 12 as the cover plate 2 rotates up and down.
The connecting column 31 and the sliding column 32 are connected by a supporting plate 33, and the connecting column 31 and the sliding column 32 are vertically connected with the supporting plate 33.
The slide groove 12 specifically includes a rising groove 121, a supporting groove 122, and a retracting groove 123, the supporting groove 122 communicates with the upper end of the rising groove 121 and extends obliquely rearward and downward, and one end of the retracting groove 123 communicates with the lower end of the supporting groove 122, and the other end communicates with the rising groove 121 laterally.
More specifically, in order to enable the support 3 to move in the sliding groove 12 more smoothly in order, the upper portion of the rising groove 121 is obliquely bent rearward and upward, and the bending position is higher than the retraction groove 123. The sliding column 32 is limited by the inclined wall at the upper part of the rising groove 121 to move upwards and backwards to the upper end of the rising groove 121 when moving upwards in the rising groove 121, and at the moment, the sliding column 32 is biased to the supporting groove 122, so that the sliding column 32 can be limited by the lower side wall of the supporting groove 122 when moving downwards from the upper end of the rising groove 121, smoothly enters the supporting groove 122, and is prevented from moving back into the rising groove 121.
The lower portion of the supporting groove 122 is bent obliquely downward and forward, and when the sliding column 32 is positioned at the lower end of the supporting groove 122, the sliding column 32 is biased to the retraction groove 123, so that the sliding column 32 can be restrained from moving upward by the top wall of the retraction groove 123 and smoothly enter the retraction groove 123 under the action of a lateral component force when the cover plate 2 is retracted.
The lower edge of the communication port between the retraction groove 123 and the rising groove 121 is provided with an inclined chamfer. Since the downward tilting force is applied to the sliding column 32 when the cover plate 2 is rotated downward, there is a possibility that the sliding column 32 is caught by the lower edge of the communication port between the retraction groove 123 and the rising groove 121, and even is caught in the retraction groove 123, and thus the tilting chamfer can guide the sliding column 32 to move downward and smoothly move downward along the rising groove 121.
In this embodiment, the inclined chamfer angles of the upper portion of the rising groove 121, the lower portion of the supporting groove 122 and the retracting groove 123 are smaller than 45 degrees compared with the inclined angle of the front end surface of the case 1, so that the movement component force of the sliding column 32 along the tangential direction of the inclined surface is larger when the sliding column moves along the inclined surface, and the sliding column 32 can move in the sliding groove 12 conveniently.
In the present embodiment, the groove widths of the rising groove 121 and the retraction groove 123 are the same as the diameter of the slide column 32.
The width of the lower end of the supporting slot 122 is the same as the diameter of the sliding column 32, but the width of the upper end is larger than the diameter of the sliding column 32, so that when the sliding column 32 is positioned at the upper end of the rising slot 121, the axis of the sliding column is positioned above the lower side edge of the supporting slot 122 and above the rear side of the lower side edge of the supporting slot 122, which is close to one end of the rising slot 121, so that the sliding column 32 can fall on the lower side wall of the supporting slot 122 when the cover plate 2 rotates downwards, and can enter the supporting slot 122 more smoothly.
In order to prevent the sliding column 32 from moving to the upper end of the rising groove 121 due to the excessive rotation of the cover plate 2 by the user when the cover plate 2 is retracted, the present application provides a protruding strip 124 on the rear side wall of the upper portion of the rising groove 121, and the protruding strip 124 is located higher than the retraction groove 123.
When the user rotates the cover plate 2 too much, the sliding column 32 is blocked by the convex strips 124, so as to remind the user; in addition, when the cover plate 2 needs to be lifted, a slightly larger force needs to be applied to overcome the resistance caused by the raised strips 124, so that the sliding column 32 can enter the upper end of the rising groove 121 and further smoothly enter the supporting groove 122, and the situation that the user cannot support the cover plate 2 due to insufficient rotation angle of the cover plate 2 can be reminded and avoided.
In order to cooperate with the supporting member 3 and to make the cover plate 2 have a set-up angle as large as possible, the slide groove 12 is provided in the center of the side face of the operation groove 11 near the front end face, and the ratio of the distances of the supporting groove 122 and the retracting groove 123 from the upper and lower faces of the operation groove 11 is about 1:3.
In this embodiment, the left and right sides of the control slot 11 are respectively provided with a sliding slot 12, a supporting member 3 is connected between each sliding slot 12 and the corresponding side edge of the cover plate 2, and the sliding slots 12 and the supporting members 3 on the two sides are respectively symmetrically arranged so as to stably support the cover plate 2, and meanwhile, the cover plate 2 can be rotated more smoothly.
In the present embodiment, when the cover plate 2 is covered on the front port of the control slot 11, the sliding column 32 is located at the lower end of the rising slot 121;
With the cover plate 2 lifted, the sliding column 32 moves upwards in the lifting groove 121, overcomes the resistance of the raised strips 124 during the lifting, and enters the upper end of the lifting groove 121, and when the sliding column is positioned at the upper end of the lifting groove 121, the lifting angle of the cover plate 2 is the largest, and the angle is preferably 90-120 degrees;
the sliding column 32 moves backward and downward under the gravity of the cover plate 2 or the force of a user turning down the cover plate 2, and moves downward along the supporting groove 122 to the lower end of the supporting groove 122 to be limited to move, so that the cover plate 2 is supported;
When the cover plate 2 needs to be retracted, the cover plate 2 is firstly rotated upwards, at the moment, the sliding column 32 moves along the retraction groove 123 under the inclined pulling force of the cover plate 2 to the ascending groove 121 until entering the ascending groove 121, at the moment, the cover plate 2 is rotated downwards, and the sliding column 32 moves along the ascending groove 121 until the cover plate 2 covers the front port of the control groove 11.
According to the modular terminal combined electrical appliance with the positionable cover plate, the cover plate 2 can be lifted up and then supported by the support column without being held by hands when in use or maintenance, so that a user can operate or maintain the modular terminal combined electrical appliance with both hands conveniently.
