Figures 1-5 The technical scheme in the embodiment of the utility model will be clearly and completely described below with specific embodiments and drawings.
[0022] The height adjustment auxiliary device in an extremely narrow case comprises a lower sliding piece 2 and an upper sliding piece 1, the upper sliding piece 1 is slidably connected to the lower sliding piece 2, the lower sliding piece 2 and the upper sliding piece 1 are both in the shape of a side-inverted triangular prism, the cross-sectional shape of the lower sliding piece 2 and the upper sliding piece 1 is a center-symmetrical two-triangle, the top end face of the lower sliding piece 2 is a slope, the bottom end face of the upper sliding piece 1 is also a slope, the two slopes contact each other, two guide sliding blocks 23 are further arranged on the top end face of the lower sliding piece 2, two guide sliding grooves 13 are correspondingly arranged on the bottom end face of the upper sliding piece 1, the guide sliding blocks 23 are slidably connected in the guide sliding grooves 13, so that the upper sliding piece 1 and the lower sliding piece 2 can reciprocally slide in the same direction and are not prone to relative rotation, which is beneficial to controlling the overall height of the device by controlling the relative sliding between the upper sliding piece 1 and the lower sliding piece 2.
[0023] The upper side of the lower slide 2 is provided with an adjusting through slot 21, and the lower side of the upper slide 1 is provided with an adjusting slot 11 corresponding to the adjusting through slot 21. Two mounting holes are oppositely provided on the two side walls of the adjusting through slot 21, and an internal thread connecting piece 22 is rotatably connected through the two mounting holes. The internal thread connecting piece 22 comprises a sleeve ring, which is a hollow cylindrical structure. Two rotating shafts are symmetrically arranged on the circular side surface of the sleeve ring. The internal thread connecting piece 22 is correspondingly assembled in the two mounting holes through the two rotating shafts, so as to realize the rotational connection of the internal thread connecting piece 22 relative to the lower slide 2. The internal thread connecting piece 22 can freely rotate in the adjusting through slot 21 of the lower slide 2, and a thread is provided on the inner surface of the sleeve ring. Two mounting holes are also provided on the two side walls in the adjusting slot 11 of the upper slide 1, and a rotating connecting piece 12 is rotatably connected through the two mounting holes. The connecting mode of the rotating connecting piece 12 is completely same as that of the internal thread connecting piece 22, and the rotating connecting piece 12 has the same result as the internal thread connecting piece 22. The rotating connecting piece 12 also comprises a sleeve ring and two rotating shafts symmetrically fixedly connected to the side surface of the sleeve ring. The difference lies in that a limiting slot is provided on the inner side surface of the sleeve ring. A regulating lead screw is further included. One end of the regulating lead screw 3 is provided with an end collar 31, the diameter of the end collar 31 is greater than the diameter of the regulating lead screw 3, the end collar 31 is rotatably connected in the limiting slot of the rotating connecting piece 12, the diameter of the end collar 31 is greater than the inner diameter of the sleeve ring and smaller than the inner diameter of the limiting slot, so that the end collar 31 can be limited in the limiting slot. The regulating lead screw 3 can move along the axial direction to drive the upper slide 1 to move. The regulating lead screw 3 is provided with external threads, and is screw-connected with the internal thread connecting piece 22 through the external threads. The internal thread connecting piece 22 is rotatably connected with the lower slide 2, so that the rotation of the regulating lead screw 3 will be shown as the relative movement of the regulating lead screw 3 relative to the lower slide 2. For the whole device, rotating the regulating lead screw 3 will make the regulating lead screw 3 move along the axial direction spirally due to the limitation of the internal thread connecting piece 22. The end collar 31 on the regulating lead screw 3 also rotates and moves. The movement of the end collar 31 will drive the rotating connecting piece 12, and the rotating connecting piece 12 will drive the upper slide 1 to move. The movement of the upper slide 1 will be along the upper end surface of the lower slide 2. The upper slide 1 slides along the inclined surface, which will change the distance between the top end surface of the upper slide 1 and the bottom end surface of the lower slide 2, so as to adjust the elevation by using the distance change.
