Description

Technical Field

[0001] The utility model relates to the technical field of mattresses, in particular to a tension-adjustable twill mattress. Background Art

[0002] At present, the tension of the trampoline mattress on the market is fixed after the trampoline is installed on the bed frame. If the trampoline is stretched tightly, the bed will feel hard, and if it is stretched loosely, the bed will feel soft. For different consumers, the same tension of the trampoline will give different experiences, making it difficult to sell and promote the trampoline mattress. Moreover, as the use time of the trampoline mattress increases, the trampoline will gradually loosen, seriously affecting the service life of the trampoline mattress. Utility Model Content

[0003] The utility model aims to provide a tension-adjustable mattress.

[0004] The purpose of the utility model is achieved in this way.

[0005] A tension-adjustable mattress, comprising a bed frame and a stretch net installed on the top of the bed frame, wherein the bed frame has an elastic deformation range, and a fixing bracket is respectively provided on two opposite sides of the inner side of the bed frame along the longitudinal direction and the transverse direction, and a nut seat is provided on each fixing bracket.

[0006] It also includes a screw rod, and the screw holes of two nut seats that are longitudinally or transversely opposite are threadedly connected by the screw rod. The screw rod rotates through the nut seat and the fixed bracket to drive the bed frame to deform elastically.

[0007] The utility model enables the bed frame to be elastically deformed through the cooperation of the screw rod and the nut seat, thereby adjusting the tension of the stretch net to adapt to different consumers. At the same time, after the stretch mattress has been used for a period of time, the stretch net can be tensioned again to extend the service life.

[0008] The above technical solution can be further improved as follows.

[0009] Furthermore, a screw rod is provided longitudinally or transversely, and both ends of the screw rod are respectively threadedly connected with a corresponding nut seat. The elastic deformation of two opposite bed frames is realized longitudinally or transversely by a screw rod, and the operation is simpler.

[0010] Furthermore, the two nut seats corresponding to the rotation of the screw rod synchronously move in directions toward or away from each other to drive the bed frame to deform elastically. The threads at both ends of the screw rod are arranged in opposite directions.

[0011] Furthermore, the screw rods in the longitudinal and transverse directions are staggered in the height direction, so that the screw rods in the longitudinal and transverse directions of the bed frame are not easy to interfere with each other.

[0012] Furthermore, an inner frame is fixed inside the bed frame, the inner frame is provided with a clearance hole, the fixing bracket passes through the clearance hole, the top surface of the inner frame is lower than the top surface of the bed frame, there is a preset height difference between the top surface of the inner frame and the top surface of the bed frame, when the tension net is pressed down to a depth exceeding the preset height difference, the top surface of the inner frame supports the tension net. The inner frame further maintains the tension in the middle part of the tension net.

[0013] Furthermore, it also includes a connecting seat, the connecting seat is respectively provided with through holes corresponding to the longitudinal and transverse screws, and the longitudinal and transverse screws pass through the corresponding through holes. The connecting seat connects the middle parts of the longitudinal and transverse screws through the connecting seat, and the middle parts of the screws are not easily deformed.

[0014] Furthermore, the connection seat is provided with a connection screw hole corresponding to each screw rod, and the other end of the screw rod is threadedly connected to the corresponding connection screw hole. Either side of the bed frame can be adjusted separately.

[0015] Furthermore, the connecting seat is annular, which is convenient for screw connection and fixing.

[0016] The utility model makes the bed frame elastically deformed by the cooperation of the screw rod and the nut seat, thereby adjusting the tension of the stretch net to suit different consumers. At the same time, after the stretch mattress has been used for a period of time, the stretch net can be re-tightened to extend the service life. The inner frame further maintains the tension of the middle part of the stretch net. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1, see Figure 1 and 3As shown, a tension-adjustable twill mattress comprises a bed frame 1, a twill 2 mounted on the top surface of the bed frame 1, a screw rod 3 and a connecting seat 4. The bed frame 1 has an elastic deformation range, and two side surfaces of the inner side of the bed frame 1 opposite to each other in the longitudinal direction and the transverse direction are respectively provided with a fixing bracket 5, and a nut seat 6 is provided on the fixing bracket 5, and the screw holes of the nut seat 6 are threadedly connected to one end of the screw rod 3, and the screw holes of two nut seats 6 opposite to each other in the longitudinal direction or the transverse direction are connected through a screw rod 3.

[0024] The connecting seat 4 is provided with through holes 41 corresponding to the longitudinal and transverse screw rods 3. The middle parts of the longitudinal and transverse screw rods 3 pass through the corresponding through holes 41, and the longitudinal and transverse screw rods 3 are staggered in height direction on the connecting seat 4, so that the longitudinal and transverse screw rods 3 are connected through the connecting seat 4.

[0025] In this way, the longitudinal or transverse screw rod 3 rotates, and the corresponding two nut seats 6 synchronously move in the direction of approaching or separating to drive the bed frame 1 to elastically deform through the nut seat 6 and the fixing bracket 5, thereby achieving the tensioning of the stretching net 2. The adjustment range of the screw rod 3 and the nut seat 6 needs to be within the elastic deformation range of the bed frame 1, and there are scale marks to guide the actual use.

[0026] Example 2, see Figure 2-4 As shown, the difference between the embodiment 1 and the embodiment 1 is that an inner frame 7 is fixed inside the bed frame 1, the inner frame 7 is provided with a clearance hole 71, the fixing bracket 5 passes through the clearance hole 71, the top surface of the inner frame 7 is lower than the top surface of the bed frame 1, and there is a preset height difference between the top surface of the inner frame 7 and the top surface of the bed frame 1. When the tension net 2 is pressed down to a depth exceeding the preset height difference, the top surface of the inner frame 7 supports the tension net 2, and the inner frame 7 tensions the middle part of the tension net 2.

[0027] Example 3, see Figure 3 and Figure 5 As shown, the difference between it and embodiment 2 is that the connection seat 4 is annular, and each nut seat 6 is connected to a screw rod 3. The connection seat 4 is provided with connection screw holes corresponding to the screw rods 3 connected to each nut seat 6, that is, the two ends of each screw rod 3 are separately connected to the connection seat 4 and the nut seat 6. In this way, each screw rod 3 can be adjusted separately, and the elastic deformation of the corresponding frame of the bed frame 1 can be adjusted by rotating the corresponding screw rod 3.

[0028] In the present invention, the bed frame 1 can be made of wood or metal, and the fixing bracket 5 and the nut seat can be integrally formed. The stretch net 2 is made of a single chemical fiber material, metal wire or natural silk material (such as palm rope), and the stretch net 2 can also be made of two or three kinds of chemical fiber materials, metal wire or natural silk materials.
