[0002] Sleeping takes up one-third of a person's life. Sufficient sleep is the guarantee of a healthy life, and pillows play an indispensable role in this process. With the improvement of living standards, people's requirements for quality of life are getting higher and higher. In order to meet the needs of different users, various pillows have appeared on the market, including bamboo pillows, cotton pillows, memory foam pillows, latex pillows, etc. However, these pillows cannot remain elastic after long-term use, and the height of the pillows cannot be effectively adjusted, which affects the comfort of use.

[0003] In order to solve the problem of deformation of pillows after long-term use, the prior art such as CN210276705U-an adjustable pillow includes a hollow pillow body, an adjustment device is provided in the pillow body, the adjustment device includes a support seat and a threaded rod, the support seat is fixedly connected to one end of the pillow body, one end of the threaded rod is threadedly connected to the support seat, the other end of the pillow body is provided with a through hole, and the other end of the threaded rod is inserted into the through hole. By providing the adjustment device in the pillow body, it is helpful to adjust the tightness of the pillow skin, and solves the problem that the existing pillows cannot reach the optimal use state due to long-term use, resulting in poor sleep quality. However, the other end of the threaded rod extends out of the pillow body. When the adjustment amount is large, the other end of the threaded rod will protrude further from the pillow body, which not only reduces the aesthetics of the pillow, but also poses a risk of scratching the human body.

[0004] Therefore, how to provide a pillow with adjustable pillow surface tightness that is not only aesthetically pleasing but also safe to use is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0005] In view of this, the utility model provides a pillow with adjustable tightness of the pillow surface which is not only capable of adjusting the tightness of the pillow surface but also aesthetically pleasing and highly safe to use.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A pillow with adjustable tightness of pillow surface, comprising: a first support frame, a second support frame, an adjustment square rod, an adjustment bolt, a pillow surface elastic sleeve, and two side sleeves, wherein the sleeve openings at both ends of the pillow surface elastic sleeve are respectively fixed to the first support frame and the second support frame, and the two side sleeves are respectively sleeved at both ends of the pillow surface elastic sleeve;

[0008] A first fixed square tube is fixed on the first support frame, one end of the adjusting square rod is inserted into a pipe opening at one end of the first fixed square tube, the adjusting bolt passes through one end of the first fixed square tube and is threadedly connected to one end of the adjusting square rod, and a second fixed square tube is fixed on the second support frame, the other end of the adjusting square rod is inserted into a pipe opening at one end of the second fixed square tube.

[0009] It can be seen from the above technical scheme that compared with the prior art, the utility model discloses a pillow with adjustable pillow surface tightness. When the pillow surface, i.e., the height (tightness) of the pillow surface elastic cover needs to be adjusted, the side cover on one side is removed, and then the adjusting bolt is rotated with a tool. Since the adjusting bolt and the adjusting square rod are threadedly connected, and the adjusting square rod can only move but not rotate under the limit of the first fixed square tube and the second fixed square tube, the adjusting square rod is extended or retracted under the drive of the adjusting bolt, thereby lengthening or shortening the distance between the first support frame and the second support frame, so that the tightness of the pillow surface elastic cover connected to the first support frame and the second support frame is in a tight or relaxed state, thereby achieving adjustable tightness (height) of the pillow surface elastic cover.

[0010] Therefore, the pillow adopts an adjusting bolt to drive the adjusting square rod to extend or retract to adjust the tightness of the elastic cover of the pillow surface, and the adjusting square rod is completely placed inside the pillow, so that when the adjusting square rod is retracted for adjustment, its end will not protrude from the outside of the pillow, which not only makes the pillow beautiful as a whole, but also does not pose a risk of scratching the human body, thereby improving safety in use.

[0011] Furthermore, the number of the first fixed square tube, the adjusting square rod, the adjusting bolt, and the second fixed square tube are all two;

[0012] The first support frame comprises:

[0013] A first support plate, one end of the pillow elastic sleeve is fixedly connected to the first support plate, and two ends of the first support plate are butted and connected by bolts to form a ring-shaped structure;

[0021] Furthermore, a spacing adjustment member is fixed between the two first fixed square tubes and the two second fixed square tubes.

[0022] The beneficial effect of adopting the above technical solution is: since an adjusting square rod needs to be connected between the first fixed square tube and the second fixed square tube, it is necessary to ensure that the positions of the first fixed square tube and the second fixed square tube are centered. Therefore, a spacing adjustment member is designed. The positions of the first fixed square tube and the second fixed square tube in the width direction of the pillow can be adjusted through the corresponding spacing adjustment member, so that the positions of the first fixed square tube and the second fixed square tube can be centered, which is convenient for the installation of the adjusting square rod.
