DETAILED DESCRIPTION

[0021] See also Figure 1-6The utility model provides the following technical solutions: a multifunctional pressure-reducing cushion, comprising a connecting plate 3, a connecting belt 4 and a strap 5, and also comprising a main body 1 and a bottom plate 2. The bottom surface of the main body 1 is provided with a bottom plate 2, and the bottom surface of the bottom plate 2 is provided with a plurality of slide rails 21. The top and bottom surfaces of the connecting plate 3 are provided with protrusions that match the slide rails 21. Both ends of the inner wall of the slide rail 21 are provided with symmetrical grooves. A fixing block 22 is installed on the inner wall groove of the slide rail 21 through a spring 25. Both ends of the protrusion of the connecting plate 3 are provided with fixing grooves 23 that match the fixing block 22. The two main bodies 1 are connected by a plurality of connecting belts 4.

[0022] The main body 1 includes a breathable layer 11, a sponge pad 12, a support column 13, a soft pad 14 and an installation layer 15. The breathable layer 11 is provided on the top surface of the main body 1, and the sponge pad 12 is provided on the bottom surface of the breathable layer 11. The soft pad 14 is installed on the main body 1, and the soft pad 14 and the sponge pad 12 are connected by several support columns 13.

[0023] The two main bodies 1 are connected together by a connecting belt 4. When the two main bodies 1 are folded together, the connecting belt 4 can be used as a handle. The length of the connecting belt 4 should be convenient for the user to hold the connecting belt 4 and to carry the cushion. The thickness of the connecting belt 4 should ensure that the connecting belt 4 will not hinder the slide rails 21 on the two main bodies 1 from docking together after the device is unfolded. When the device is in a folded state, the two main bodies 1 can be fixed together by the protrusions at the top and bottom of the connecting plate 3 and the slide rails 21 on the two main bodies 1, thereby ensuring the stability of the cushion in the folded state. When the cushion is unfolded, the slide rails 21 on the two main bodies 1 are docked together, and the slide rails 21 on the two main bodies 1 can be connected together by the connecting plate 3. The connecting plate 3 plays a supporting role, thereby ensuring the stability of the cushion after unfolding, making it convenient for the user to place his legs on the unfolded cushion so that the user can rest in a semi-reclining state, thereby improving the patient's comfort when resting. By setting a number of slide rails 21, the working effect of the connecting plate 3 is ensured The fixing grooves 23 provided on the two ends of the connecting plate 3 are positioned to ensure that the fixing grooves 23 can cooperate with the fixing blocks 22 on the two slide rails 21 at the same time, ensuring the stability of the connecting plate 3. The side wall of the fixing block 22 is shaped as an inclined surface inclined toward one end of the slide rail 21 extending toward the fixing block 22, and the inclined surface of the fixing block 22 faces the connecting plate 3, ensuring that the connecting plate 3 can push the fixing block 22 when the user moves the connecting plate 3, avoiding obstruction in the process of the user moving the connecting plate 3. The spring 25 ensures that the pushed fixing block 22 can quickly return to its original position, ensuring the working effect of the fixing block 22.

[0024] The breathable layer 11 and the sponge pad 12 are breathable structures. During the use of the seat cushion, a large amount of heat can be prevented from accumulating in the part where the user contacts the breathable layer 11 due to the poor air permeability of the device, which affects the comfort of the user. The support column 13 plays a role in supporting the breathable layer 11 and the sponge pad 12, and prevents the breathable layer 11 and the sponge pad 12 from being over-squeezed during use, which affects the working effect of the breathable layer 11 and the sponge pad 12. By setting a number of support columns 13, the working effect of the support columns 13 is guaranteed. When the user sits on the seat cushion, the support column 13 in contact with the user presses down, and the breathable layer 11, the sponge pad 12 and the soft pad 14 are deformed, thereby ensuring the decompression effect of the device. The breathable layer 11 and the sponge pad 12 also play a buffering role, preventing the support column 13 from affecting the comfort of the device. The breathable layer 11, the sponge pad 12 and the soft pad 14 are made of materials with strong elasticity, which ensures that the breathable layer 11, the sponge pad 12 and the soft pad 14 can return to their original positions after deformation, thereby ensuring the decompression effect of the device.

[0025] Specifically, the material of the support column 13 is rubber.

[0026] The material of the support column 13 ensures that the support column 13 will deform when compressed, thereby preventing the support column 13 from hindering the deformation of the breathable layer 11 and the sponge pad 12, which would affect the decompression effect of the device. The material of the support column 13 also reduces the damage to the support column 13 caused by collisions between the support columns 13 during movement, thereby increasing the service life of the support column 13.

[0027] Specifically, a mounting layer 15 is provided on the opposite surfaces of the sponge pad 12 and the soft pad 14 , the support column 13 is installed on the mounting layer 15 , and a protrusion is provided on the portion of the support column 13 located inside the mounting layer 15 .

[0028] The mounting layer 15 is used to mount the support column 13, which reduces the damage to the sponge pad 12 and the soft pad 14 during use and extends the service life of the sponge pad 12 and the soft pad 14. The mounting layer 15 is a breathable structure to prevent the breathability of the device from being affected. The protruding side wall of the support column 13 ensures the stability of the support column 13 after being installed on the mounting layer 15.

[0029] Specifically, a plurality of reinforcing plates 24 are provided between the slide rails 21 .

[0030] The reinforcing plates 24 improve the strength of the bottom plate 2, ensure the stability of the device after unfolding, and prevent the unfolded main body 1 from being unable to support the user's legs. By providing a plurality of reinforcing plates 24, the working effect of the reinforcing plates 24 is ensured.

[0031] Specifically, a reinforcing block 32 that matches the space between the slide rails 21 is provided on the bottom surface of the connecting plate 3 , and a moving groove 31 is provided on the side wall of the reinforcing block 32 .

[0032] The reinforcing block 32 improves the strength of the connecting plate 3 and ensures the stability of the connection between the slide rails 21 on the two main bodies 1. The shape of the reinforcing block 32 ensures that the reinforcing plate 24 will not hinder the user from moving the connecting plate 3. The moving groove 31 facilitates the user to move the connecting plate 3, and is convenient for the user to move the connecting plate 3 when the two main bodies 1 are folded together, and is convenient for the user to release the coordination between the fixed block 22 and the fixed groove 23. The shape of the edge of the slide rail 21 is an arc, which improves the comfort of the user when moving the connecting plate 3. The position of the moving groove 31 is located on the side wall of the reinforcing block 32 away from the connecting belt 4, which is convenient for the user to move the connecting plate 3 through the moving groove 31.

[0033] Specifically, a protrusion is provided on the side wall of the fixing block 22 , and a groove matching with the protrusion on the side wall of the fixing block 22 is provided on the side wall of the groove in which the slide rail 21 is installed to install the fixing block 22 .

[0034] The cooperation between the side wall protrusion of the fixed block 22 and the side wall groove of the groove of the slide rail 21 for installing the fixed block 22 plays a limiting role, preventing the fixed block 22 from escaping from the groove for installing the fixed block 22 during movement, which affects the working effect of the fixed block 22.

[0035] Specifically, a plurality of straps 5 are provided on both sides of the main body 1 .

[0036] The user can fix the seat cushion on the seat by means of the strap 5, thus ensuring the stability of the seat cushion during use.

[0037] The working principle and use process of the utility model are as follows: when the device is used, the seat cushion is fixed to the seat by the strap 5. When the user sits down, the support column 13 in contact with the user is compressed, the support column 13 starts to move, the breathable layer 11, the sponge pad 12 and the soft cushion 14 are deformed, and the shape of the main body 1 is deformed to a shape suitable for the user, which plays a role in decompression. When the user lies down to rest, the fixation of the strap 5 is released, and the connecting plate 3 is pulled by the moving groove 31. The connecting plate 3 pushes the fixing block 22 during the movement, and the cooperation between the connecting plate 3 and the slide rail 21 is released. The connecting plate 3 is pulled out of the slide rail 21, and the main body 1 is moved to make the slide rails 21 on the two main bodies 1 dock together, and the slide rails 21 on the two main bodies 1 are connected together by the connecting plate 3, and the connecting plate 3 is fixed by the cooperation of the fixing block 22 and the fixing groove 23, and the unfolded seat cushion is fixed to the seat by the strap 5.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
