DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present application, and the technical solutions of the present application are further described in conjunction with the accompanying drawings, but the present application is not limited to these embodiments, and the following embodiments do not limit the invention involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required by the solutions of the invention.

[0028] The principles and structures of the present application will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Embodiment one As Figure 1 , 2As shown, a power distribution box mounting device for mounting a power distribution box into a reserved slot 5 in a wall surface, comprising a long strip-shaped transverse guide rail 1, and horizontal rods 2 for lifting the power distribution box 14, two lifting mechanisms are arranged side by side on the transverse guide rail 1, the two lifting mechanisms are respectively a first lifting mechanism and a second lifting mechanism, the two lifting mechanisms are respectively connected to and drive one horizontal rod 2 to move up and down, the two horizontal rods 2 are rotatably connected through an axis hinge 13, a jacking head 3 vertically facing the transverse guide rail 1 is arranged on the axis hinge 13, the lifting mechanism can be controlled by a moving mechanism to move along the transverse guide rail 1, so as to adjust the position of the two lifting mechanisms or the distance between the two, by adjusting the position of the lifting mechanism, the corresponding position of the two horizontal rods 2 in the up-down direction can be adjusted, so that the power distribution box 14 on the two horizontal rods 2 corresponds to the reserved slot 5 up and down. By adjusting the distance between the two, the axis hinge 13 can be further close to or away from the transverse guide rail 1, so that the jacking head 3 pushes the power distribution box 14 towards the reserved slot 5 or away from the reserved slot 5. The jacking head 3 is connected with the rotating shaft of the axis hinge 13 through a jacking rod 4, so that the jacking head 3 protrudes forward by a certain length, so as to more effectively push the power distribution box 14 into the reserved slot 5.

[0030] As shown in Figure 3 , 4 , 5, in use, first make the horizontal rod 2 below the reserved slot 5, place the power distribution box 14 on the horizontal rod 2, then make the horizontal rod 2 rise to lift the power distribution box 14 to a height corresponding to the reserved slot 5, then adjust the distance between the two lifting mechanisms to be larger, so that the included angle of the two horizontal rods 2 is larger, and then the jacking head 3 pushes the power distribution box 14 towards the reserved slot 5, so as to push the power distribution box 14 into the reserved slot 5.

[0031] The horizontal rod 2 rotates a roller 6 for carrying the power distribution box 14, the rollers 6 of the two horizontal rods 2 are flush to support the bottom surface of the power distribution box 14, when the power distribution box 14 moves relative to the horizontal rod 2, the rolling of the roller 6 is beneficial to reduce the friction of the power distribution box 14. Of course, the end of the roller 6 should be kept a certain distance from the axis hinge 13 to avoid affecting the angle change of the two horizontal rods 2, so that the included angle of the two horizontal rods 2 can reach a certain small angle, so as to facilitate the lifting use of the power distribution box 14 with a certain thickness.

[0032] The first lifting mechanism and the second lifting mechanism are both lead screw 7 driving mechanisms, and the horizontal rod 2 is connected with the nut 8 of the lead screw 7 driving mechanism.

[0033] The screw rod 7 driving mechanism is a mechanical transmission system for converting rotary motion into linear motion, mainly composed of a screw rod 7, a nut 8, a driving motor 9 and a support and guide assembly. The motor 9 drives the screw rod 7 to rotate, and the nut 8 moves axially along the screw rod 7, thereby realizing the linear displacement of the workpiece. The trapezoidal screw rod 7 has simple structure and large carrying capacity, the ball screw 7 has small friction and high efficiency, and can be used for precise positioning and automatic transmission occasions.

[0034] The moving mechanism includes a telescopic cylinder 11 and a sliding sleeve 10 sleeved on the screw rod 7 of the screw rod 7 driving mechanism, and the sliding sleeve 10 is located below the nut 8. The telescopic cylinder 11 can be an electric cylinder, a gas cylinder, a hydraulic cylinder or other devices that can conveniently adjust the length, thereby conveniently adjusting the distance between the two screw rods 7, i.e. controlling whether the push head 3 pushes the distribution box 14. Of course, other methods that can control the movement of the screw rod 7 along the guide rail can also be used.

[0035] Further, the embodiment further includes a longitudinal guide rail 12 perpendicular to the transverse guide rail 1, and the front end of the longitudinal guide rail 12 is connected to the middle part of the transverse guide rail 1. A third lifting mechanism is arranged to slide on the longitudinal guide rail 12, the third lifting mechanism is connected with the shaft hinge 13 and drives the shaft hinge 13 to synchronously lift with the horizontal rod 2, and provides upward jacking force for the shaft hinge 13, so that the horizontal rod 2 is more balanced in force, and the lifting of the distribution box 14 is stable.

[0036] The third lifting mechanism is a screw rod 7 driving mechanism, the nut 8 of the screw rod 7 driving mechanism is connected with the rotating shaft of the shaft hinge 13, and the push head 3 is fixed on the rotating shaft of the shaft hinge 13.

[0037] The motors 9 of the screw rod 7 driving mechanism of the embodiment are arranged on the sliding block 15, and the sliding block 15 is arranged to slide on the guide rail.

[0038] Since the third lifting mechanism is freely arranged to slide on the longitudinal guide rail 12, the third lifting mechanism can automatically follow the movement of the horizontal rod 2, thereby always maintaining the lifting effect on the shaft hinge 13 and ensuring the stable lifting of the horizontal rod 2.

[0039] Further, the push surface of the push head 3 is provided with an anti-skid layer 16 to avoid the relative movement of the distribution box 14 in the horizontal direction with respect to the push head 3, and to ensure the stability of the movement direction of the distribution box 14.

[0040] Further, as shown in FIG. 6, the push head 3 is provided with a plurality of push rods 17, and the push rods 17 are arranged to be parallel to each other and arranged in the horizontal direction. Figure 6As shown, the transverse guide rail is provided with a telescopic adjusting rod 17 perpendicular to the transverse guide rail at both ends. The telescopic adjusting rod 17 can be an electric cylinder, a gas cylinder, a hydraulic cylinder or other devices capable of telescoping. The telescopic adjusting rod 17 can be used to support between the transverse guide rail and the opposite wall, thereby avoiding the movement of the transverse guide rail.

[0041] Embodiment two As Figure 7 , 8 As shown, unlike the above embodiment, two horizontal rods 2 are hingedly connected with two connecting rods 18 to form a parallelogram mechanism. Specifically, the end portions of the two horizontal rods 2 connected with the shaft hinge 13 extend outwardly by a certain length of rod body and are hingedly connected with the end portions of the two connecting rods 18 respectively. The other end portions of the two connecting rods 18 are both connected with a sliding sleeve 10 which is slidably sleeved on the lead screw 7, so that the two horizontal rods 2 and the two connecting rods 18 form a parallelogram mechanism.

[0042] The nut 8 of the lead screw 7 driving mechanism of the third lifting mechanism is located below the sliding sleeve 10, so that the nut 8 can push the sliding sleeve 10 upwardly, thereby realizing the upward pushing of the horizontal rod 2. The nut 8 is connected with one end of the pushing rod 4, and the other end of the pushing rod 4 is connected with the pushing head 3. The pushing rod is provided with a sliding groove 19, and the rotating shaft of the shaft hinge 13 is in sliding fit with the sliding groove 19. Thus, when the included angle of the two horizontal rods 2 changes, the parallelogram mechanism deforms synchronously. Therefore, the forward extension length of the pushing head 3 relative to the shaft hinge 13 changes, so that the closer the shaft hinge 13 is to the reserved groove 5, the longer the pushing head 3 extends forwardly relative to the shaft hinge 13, thereby facilitating the better pushing of the distribution box 14 into the reserved groove 5. When the first lifting mechanism and the second lifting mechanism move close to each other, the included angle of the two horizontal rods 2 becomes smaller, and then the parallelogram mechanism deforms, so that the pushing head 3 moves backwardly relative to the hinge shaft, thereby increasing the distance between the pushing head 3 and the transverse guide rail, and facilitating the placement of the distribution box 14 with greater thickness on the horizontal rod 2.
