Therefore, it is necessary to design a height-adjustable pillow to meet the requirements of different people or different sleeping postures on the height of the pillow.
Disclosure of Invention
The utility model aims at overcoming the defects of the prior art and providing a pillow with adjustable height, which can meet the requirements of different people or different sleeping postures on the height of the pillow.
The technical scheme of the utility model is that: the height-adjustable pillow comprises a pillow body; it also comprises a lifting mechanism embedded in the pillow body; the lifting mechanism comprises a base, a lifting platform, a screw rod, a nut, a connecting rod and a transmission assembly; the base is rectangular, a sleeve is fixedly connected at the four corners of the upper end of the base, and the sleeve is vertically arranged and is open at the upper end; the lifting platform is rectangular, the four corners of the lower end of the lifting platform are fixedly connected with butt-joint rods, and the lifting platform is movably sleeved in the sleeves at the four corners of the upper end of the base through the butt-joint rods at the four corners of the lower end of the lifting platform; two ends of the screw rod are movably arranged on the base and are horizontally arranged, a thread section A and a thread section B are respectively arranged at two ends of the screw rod, the rotating directions of the thread section A and the thread section B are opposite, the number of the screw rods is two, and the two screw rods are parallel to each other and are arranged at equal height; the four nuts are respectively in threaded connection with the threaded sections A of the two screw rods and the threaded sections B of the two screw rods; one ends of the four connecting rods are respectively hinged with the four nuts, and the other ends of the four connecting rods are respectively hinged at four corners of the lower end of the lifting platform; the transmission assembly is associated with the two screw rods to drive the two screw rods to synchronously rotate in the same direction, and then the lifting platform is driven to move up and down along the sleeve of the base through the power transmission of the nut and the connecting rod.
The utility model discloses further technical scheme is: the transmission assembly comprises a gear A, a gear shaft, a gear B and a gear C; the gear A is movably arranged on the base through a gear shaft; the gear B and the gear C are respectively and fixedly arranged on the two screw rods, symmetrically arranged on two sides of the gear A and meshed with the gear A.
The utility model discloses still further technical scheme is: it also comprises a handle arranged outside the pillow body; the handle is fixedly connected to the gear shaft.
Compared with the prior art, the utility model have following advantage:
1. the height of the pillow can be adjusted by rotating the handle, the requirement of different people or different sleeping postures on the height of the pillow can be met, and the adjusting process is convenient and smooth without pause and frustration.
2. The lifting platform is sleeved on the sleeve of the base through the butt joint rod; on one hand, the structure can play a role in guiding the lifting process of the lifting platform; on the other hand, when the user sleeps, the weight of the head cannot be evenly distributed on the lifting platform, the lifting platform tends to incline due to single-side compression, the structure can offset the single-side compression inclination tendency of the lifting platform, and the hinge structures at two ends of the connecting rod are prevented from being damaged due to long-time unbalanced stress of the lifting platform.
The invention is further described below with reference to the figures and examples.

fig. 2 is a top view of the present invention;
fig. 3 is a schematic structural diagram of the lifting table.
Description of the drawings: the lifting table and connecting rods in fig. 2 are not shown for ease of illustration of the internal structure.
Detailed Description
Example 1:
as shown in fig. 1-3, the pillow with adjustable height comprises a pillow body (not shown), a lifting mechanism embedded in the pillow body, and a handle arranged outside the pillow body.
The lifting mechanism comprises a base 1, a lifting platform 2, a screw rod 3, a nut 4, a connecting rod 5 and a transmission assembly.
The base 1 is rectangular, a sleeve 11 is fixedly connected to four corners of the upper end of the base, and the sleeve 11 is vertically arranged and is open at the upper end. The lifting platform 2 is rectangular, the four corners of the lower end of the lifting platform are fixedly connected with butt-joint rods 21, and the lifting platform 2 is movably sleeved in the sleeves 11 at the four corners of the upper end of the base 1 through the butt-joint rods 21 at the four corners of the lower end of the lifting platform. Two ends of the screw rod 3 are movably arranged on the base 1 and are horizontally arranged, two ends of the screw rod 3 are respectively provided with a thread section A31 and a thread section B32, the thread directions of the thread section A31 and the thread section B32 are opposite, the number of the screw rods 3 is two, and the two screw rods 3 are parallel to each other and are arranged at the same height.
