Description

Technical Field

[0001] The utility model relates to the technical field of mattresses, in particular to a spring mattress with adjustable hardness. Background Art

[0002] Spring mattress is a common type of mattress, mainly composed of springs. According to the shape and structure of the springs, spring mattresses can be divided into two main types: continuous spring mattresses and independent spring mattresses. Spring mattress is a common type of mattress, suitable for users who need support and elasticity. When choosing, choose a suitable spring mattress according to your needs and preferences to ensure a comfortable sleeping experience.

[0003] During the use of existing spring mattresses, the hardness of the mattress itself is fixed due to the setting of the springs, and the hardness depends on the spring elasticity coefficient. Therefore, it is not convenient to adjust the hardness of the mattress according to needs, and it is difficult to provide users with certain cooling measures in hot weather such as summer vacation, which makes the user experience not good in hot weather. Therefore, it is necessary to design a spring mattress with adjustable hardness. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-5 As shown, a spring mattress with adjustable hardness comprises a frame 1, a rotating drum 2 is rotatably connected to the inner bottom wall of the frame 1, a screw 3 is threadedly connected to the inner wall of the rotating drum 2, a sleeve 4 is fixedly connected to the inner bottom wall of the frame 1, a sleeve rod 5 is slidably connected to the inner wall of the sleeve 4, and a cross plate 51 is fixedly connected to the top of the screw 3 and the sleeve rod 5;

[0023] In this embodiment, an independent spring 6 is disposed on the upper surface of the transverse plate 51 , an inner liner 7 is disposed on the top end of the independent spring 6 , and an outer pad 8 is disposed on one side of the outer surface of the frame 1 .

[0024] During specific use, the rotating drum 2 can perform threaded motion with the screw 3 when it rotates. Due to the sliding motion of the sleeve rod 5 and the sleeve 4 and the fact that the sleeve rod 5 and the screw 3 are fixedly connected to the cross plate 51, the screw 3 can be extended and retracted from the rotating drum 2 under the threaded motion of the rotating drum 4 and the screw 3. When the screw 3 is extended, the cross plate 51 can be driven to move. At this time, the sleeve rod 5 slides in the sleeve 2, and the cross plate 51 drives the independent spring 6 to move upward. Under the reverse force of the outer pad 8 and the inner pad 7, the independent spring 6 is compressed, thereby exerting a reverse force on the outer pad 8 and the inner pad 7. At this time, the hardness of the mattress increases, and the hardness of the mattress can be adjusted according to usage needs.

[0025] In this embodiment, a mounting groove 9 is formed on the lower surface of the frame 1 , and a twisting disk 10 is rotatably connected to the inner wall of the mounting groove 9 .

[0026] During specific use, the twisting disk 10 can be rotated on the inner top wall of the installation groove 9 by manually twisting it.

[0027] In this embodiment, one end of the rotating drum 2 passes through the inner bottom wall of the frame 1 and extends to the inner side wall of the mounting groove 9 , and one end of the rotating drum 2 is fixedly connected to the twisting disk 10 .

[0028] During specific use, when the twisting disk 10 rotates, it can drive the rotation of the rotating drum 2 through its fixed connection with the rotating drum 2 and make it perform threaded motion with the screw rod 3.

[0029] In this embodiment, a groove 11 is formed on the upper surface of the outer pad 8 , and a cooling pad 12 is disposed on the inner wall of the groove 11 .

[0030] During specific use, the cooling pad 12 is disposed inside the groove 11 to prevent the cooling pad 12 from affecting the smoothness of the outer pad 8 .

[0031] In this embodiment, the inner bottom wall of the groove 11 is provided with a Velcro velvet surface 13, the cooling pad 12 is made of PVC soft glue, and the inner wall of the cooling pad 12 is filled with polymer ice crystals.

[0032] During specific use, the polymer ice crystals filled in the cooling pad 12 can provide a certain cooling effect for the user when used in hot weather.

[0033] In this embodiment, the lower surface of the cooling pad 12 is provided with a Velcro adhesive surface 14 .

[0034] During specific use, the cooling pad 12 can be fixed in the groove 11 after the Velcro adhesive surface 14 is bonded to the Velcro velvet surface 13 , thereby fixing the position of the cooling pad 12 .

[0035] Working principle: In use, when the drum 2 rotates, it can perform a threaded motion with the screw 3. Due to the sliding motion of the sleeve rod 5 and the sleeve 4 and the fact that the sleeve rod 5 and the screw 3 are fixedly connected to the cross plate 51, the screw 3 can be extended and retracted from the drum 2 under the threaded motion of the drum 4 and the screw 3. When the screw 3 is extended, the cross plate 51 can be driven to move. At this time, the sleeve rod 5 slides in the sleeve 2, and the cross plate 51 drives the independent spring 6 to move upward. Under the reverse force of the outer pad 8 and the inner pad 7, the independent spring 6 is compressed, thereby A reverse force is applied to the outer pad 8 and the inner pad 7. At this time, the hardness of the mattress increases and the hardness of the mattress can be adjusted according to usage needs. The Velcro sticky surface 14 on the lower surface of the cooling pad 12 is bonded to the Velcro suede surface 13 on the inner bottom wall of the groove 11. At this time, the position of the cooling pad 12 can be fixed. The polymer ice crystal material filled in the cooling pad 12 can provide a certain cooling method for the user in hot weather such as summer, thereby improving the comfort of the user when using the mattress in hot weather and improving the user experience.
