Description

Technical Field

[0001] This utility model relates to the field of seat cushion technology, specifically a seat cushion that is easy to install and replace. Background Technology

[0002] A seat cushion is a mat used to enhance comfort, typically placed on chairs, sofas, or other furniture. Their primary function is to provide extra comfort, and they also serve a decorative purpose. Seat cushions are often square, round, or oval in shape, and are made from materials such as cotton, velvet, brocade, nylon, or linen, with memory foam considered a particularly comfortable material.

[0003] Currently, most wheelchair seat cushions on the market are directly fixed to the frame. When the cushion is damaged or needs cleaning, it is difficult to remove it, resulting in reduced maintenance efficiency. Therefore, a seat cushion that is easy to install and replace is proposed.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides a technical solution: a seat cushion that is easy to install and replace, including a seat cushion 1;

[0025] A groove and ventilation hole are formed on the top surface of the seat cushion 1;

[0026] The seat cushion 1 and the mounting base 2 located below it are characterized in that: a connecting component 30 is provided between the seat cushion 1 and the mounting base 2; the connecting component 30 includes a rotating rod 304, the top surface of which extends through the bottom surface of the mounting base 2 into the interior of the mounting base 2; a double-threaded rod 305 and two sliders 307 are provided above the rotating rod 304, the two sliders 307 are symmetrically arranged; bevel gears 306 are fixedly sleeved on both the surface of the double-threaded rod 305 and the surface of the rotating rod 304; the two bevel gears 306 are engaged at an inclined surface; the left end face of the double-threaded rod 305 extends through the right side of the two sliders 307 to the left side of the two sliders 307. The mounting base 2 has through slots on both its left and right sides. A connecting plate 308 is fixedly connected to the left end of the slider 307. The left end of the connecting plate 308 extends through the inner side of the mounting base 2 and the through slot to the left side of the mounting base 2. A C-shaped frame 309 is fixedly connected to the left side of the connecting plate 308. The seat cushion 1 is connected to the mounting base 2 by the connecting assembly 30, the connecting rope 301 and the connecting base 302. At the same time, the double-ended threaded rod 305 drives the two sliders 307 to move, so that the connecting plate 308 drives the C-shaped frame 309 to move and fix it on the frame, thereby installing the seat cushion 1. This facilitates the subsequent installation and removal of the seat cushion 1 and improves the efficiency of seat cushion maintenance.

[0027] A connecting rope 301 is provided above the seat cushion 1. Both ends of the connecting rope 301 pass through the top surface of the seat cushion 1 and the ventilation hole and extend to the bottom of the seat cushion 1. There are two connecting ropes 301, which are symmetrically arranged on the left and right sides of the rotating rod 304.

[0028] The bottom surface of the mounting base 2 is fixedly connected to the connecting base 302, and the inner bottom surface of the connecting base 302 is fixedly connected to the protective pad 303.

[0029] The surface of the rotating rod 304 is perpendicular to the double-threaded rod 305, and both the surface of the rotating rod 304 and the surface of the double-threaded rod 305 are rotatably connected to the inner wall of the mounting base 2 through the bearing seat.

[0030] Example 2: Based on Example 1, a preferred embodiment of the present invention provides a seat cushion that is easy to install and replace. Figure 1 , Figure 3 , Figure 4 and Figure 6As shown: It also includes a locking component 31; the locking component 31 includes a support plate 311 fixedly connected to the bottom surface of the mounting base 2, an electric push rod 312 fixedly connected to the right side of the support plate 311, the left end of the output rod of the electric push rod 312 extending through the right side of the support plate 311 to the left side of the support plate 311, a fixing block 313 fixedly connected to the left end of the output rod of the electric push rod 312, a locking plate 314 fixedly connected to the left end of the fixing block 313, and a rotating plate 315 fixedly connected to the bottom end of the rotating rod 304. The surface of the rotating plate 315 has a through slot adapted to the locking plate 314, and the left end of the locking plate 314 slides through the surface of the rotating plate 315 to the inside of the slot. By using the locking component 31, the locking plate 314 moves into the slot, thereby locking the rotating plate 315 and the rotating rod 304, preventing the rotating rod 304 from rotating after adjustment, improving the stability of the connection of the mounting base 2, and thus improving the stability of the connection of the cushion 1.

[0031] In use, the connecting rope 301 is passed through the vent and tied between the connecting seats 302; the seat cushion 1 is placed on the frame, and the rotating plate 315 is rotated, causing the rotating rod 304 to rotate and drive the connected bevel gear 306 to rotate. Through the meshing transmission of the two bevel gears 306, the double-threaded rod 305 is rotated, thereby causing the two sliders 307 to move away from each other, and driving the connecting plate 308 and the C-shaped frame 309 to move outward, so that the two C-shaped frames 309 are locked on the frame, thus realizing the installation of the seat cushion 1; after installation, the electric push rod 312 is turned on, and the output rod of the electric push rod 312 extends, driving the connected fixing block 313 to move to the left, so that the locking plate 314 moves into the locking slot, thereby locking the rotating plate 315 and the rotating rod 304;

[0032] When it is necessary to remove the seat cushion 1, rotate the rotating plate 315 in the opposite direction so that the C-shaped brackets 309 come closer to each other and slide off the frame, thereby removing the mounting base 2 from the frame, and then untying the connecting rope 301, so that the seat cushion 1 can be removed for replacement.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
