Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

The closet door opening and closing device comprises an expansion link 1, a slide block 2, a thimble 3, a base 4, a spring 5 and a rubberizing 6. FIG. 1 shows, base 4 is hollow cuboid, and slider 2 is the cuboid, and slider 2's size matches with base 4's cavity square groove size, and slider 2 can the horizontal slip in base 4's square groove, has the recess that one section closed curve formed in the slider 2. The thimble 3 is an elastic long rod, one end of the thimble 3 is fixed with the base 4, the other end of the thimble 3 is provided with a contact 31, and the contact 31 is vertical to the axis of the long rod of the thimble 3. Preferably, the contact 31 is provided with a movable head that can rotate. The contacts 31 are sized to match the grooves on the slider 2.

Five key positions of a groove A, B, C, D and an E formed by a closed curve on the sliding block 2, wherein A is arranged at one end edge of the sliding block 2, the position A is directly connected with a horizontal straight line and the position B through an incline, the position B is directly connected with the horizontal straight line and the position C through an incline, the position C is connected with the position D through a horizontal straight line, the position D is connected with the position E through a horizontal straight line, and the position E is connected with the position A through a horizontal straight line.

One end of the sliding block 2 is provided with a telescopic rod 1, the telescopic rod 1 penetrates through a small hole in the base 4 and extends out of the base 4, and the telescopic rod 1 and the sliding block 2 move together. Two ends of the spring 5 are respectively fixed on one end of the sliding block 2 and the base 4.

The working principle of the utility model is as follows:

as shown in fig. 5, a cabinet door opening and closing device is installed in a cabinet body, when the door of the cabinet body is closed, the door touches a telescopic rod 1 to move, and the telescopic rod 1 drives a sliding block 2 to move.

Fig. 1 shows an initial state of the cabinet door opening and closing device, in which the contact 31 is at the position a in fig. 3, and the extension rod 1 is extended. When the door of the box body is closed, the telescopic rod 1 can be touched to move, the telescopic rod 1 can drive the sliding block 2 to move towards the other end of the base 4, the groove formed by the closed curve on the sliding block 2 enables the contact 31 to move towards the left lower side along the groove and then move towards the left to the position B, and the position B is shown in fig. 6. Because of the elasticity of the metal material of the thimble 3 and the elasticity provided by the spring 5, the contact 31 moves upward, then moves to the right upper direction, and then moves to the C position, as shown in fig. 7. At this time, the telescopic rod 1 is completely arranged in the base 4, and the door of the box body is tightly closed. When the door of the box body needs to be opened, the door of the box body is pushed inwards, the door of the box body pushes the telescopic rod 1 rightwards again, and the contact 31 moves leftwards to the position D (at the moment, the telescopic rod is in a contraction state), as shown in fig. 8. Because of the elasticity of the metal material of the thimble 3 and the elastic force provided by the spring 5, the contact 31 moves to the position E, as shown in fig. 9. Because of the spring force provided by the spring 5, the contact 31 will move to the a position, back to the starting position. At the moment, the sliding block 2 and the telescopic rod 1 move leftwards to jack the door of the box body, and a cycle action is completed.

The utility model discloses during the installation of cupboard door switch device, only need to tear the surface film of rubberizing 7, paste in cupboard or similar department can.
