[0049] In the prior art, although there are a large number of seats with a sitting posture adjustment function, and they can all achieve a good sitting posture correction effect. However, their overall structure is relatively complex and the price is relatively high; at the same time, in some designs, in order to pursue the correction effect, there are too many restrictions on the user, which is likely to cause discomfort to the user.

[0050] In addition, the sitting posture correction seats in the prior art are inconvenient to use when used as regular seats, making the use scenarios of the seats relatively narrow.

[0051] The utility model aims to provide a sitting posture correction seat with a simple structure and low cost. And when the seat does not need to correct the sitting posture, it does not affect its use as a regular seat at all.

[0052] The following further describes the utility model with specific embodiments.

[0053] Embodiment 1

[0054] As Figure 1 shown, a sitting posture correction seat of this embodiment includes a seat body 1 and a correction mechanism 2 located on the seat body 1. Among them, the correction mechanism 2 is used to assist in correcting the sitting posture of the user.

[0055] Referring to Figure 2 shown, the seat body 1 is the same as a regular seat, and it includes a seat surface 11, a backrest 12, and a chair leg assembly 13.

[0056] The chair leg assembly 13 includes a support base 131 and support legs 132. Among them, the support base 131 is integrally in a "U" shape, and it serves as the support foundation of the entire seat.

[0057] There are two support legs 132, which are respectively arranged on two side edges of the support base 131. The seat surface 11 is arranged on the support legs 132, and the support legs 132 stably support it. And a receiving groove 111 cooperating with the correction mechanism 2 is provided on the seat surface 11.

[0058] Referring to Figure 3 shown, the correction mechanism 2 includes a telescopic member 21 and a stop block 22 arranged on the top of the telescopic member 21. After the telescopic member 21 drives the stop block 22 to rise, it can assist in correcting the sitting posture of the user; after driving the stop block 22 to descend, the stop block 22 just snaps into the receiving groove 111, and its top surface is not higher than the top surface of the seat surface 11.

[0059] Preferably, the shape of the stop block 22 matches the shape of the receiving groove 111, and when the stop block 22 is located in the receiving groove 111, the top surface of the stop block 22 is flush with the top surface of the seat surface 11.

[0060] Specifically in this embodiment, the side of the stop block 22 facing the chair back 12 is designed to be arc-shaped, and the receiving groove 111 is an arc-shaped notch provided on the side of the seat surface 11 away from the chair back 12 .

[0061] That is, when the stop block 22 is completely inserted into the receiving groove 111 , the gap can be filled, thereby forming a “complete” chair seat 11 .

[0062] Furthermore, the stop block 22 , the seat surface 11 and the seat back 12 are all provided with cushions.

[0063] It is worth noting that the telescopic member 21 in this embodiment can be an electric telescopic rod, a mechanical telescopic rod, or other forms in the prior art, which will not be described in detail here.

[0064] The embodiment of the posture correction chair is provided with a receiving groove 111 on the seat surface 11 that matches the correction mechanism 2. When the telescopic member 21 drives the stop block 22 to rise to a certain height (refer to Figure 1 The telescopic member 21 and the stopper 22 thereon can prevent the user from sitting in a bad posture due to the transition of the body forward without excessively restricting the user; in addition, after the stopper 22 is lowered, it can be just stuck in the receiving groove 111 on the seat surface 11 (refer to Figure 10 state) to form a "complete" chair surface 11. At this time, the sitting posture correction chair is the same as a normal chair and will not cause any interference to its normal use.

[0065] Example 2

[0066] This embodiment is an embodiment of the correction mechanism 2.

[0067] refer to Figure 3 、 Figure 4 As shown, the telescopic member 21 includes a first rod 211 and a second rod 212 that are sleeved together. The first rod 211 is sleeved on the second rod 212, and the two rods are locked and released by a locking assembly 23.

[0068] The locking assembly 23 includes a ferrule 231 and a locking bolt 232. The ferrule 231 is sleeved onto the first rod 211. Mounting holes for the locking bolt 232 are formed at corresponding positions on the ferrule 231 and the first rod 211, and at least one of the mounting holes is a threaded hole that mates with the locking bolt 232.

[0069] The end of the locking bolt 232 is connected to a limiting washer 233 , and a slot for the limiting washer 233 to move is formed on the inner wall of the first rod 211 .

[0070] In the posture correction chair of this embodiment, in the non-fastened state, the limiting gasket 233 is located in the groove on the inner wall of the first rod 211 and does not contact the second rod 212; at this time, the second rod 212 can move freely up and down.

[0071] When tightening is required, the locking bolt 232 is rotated to drive the limiting washer 233 to move toward the second rod body 212 and press against the outer surface of the second rod body 212 , thereby achieving a locking operation on the second rod body 212 .

[0072] In this embodiment, the setting of the limiting gasket 233 can increase the contact area with the second rod body 212, which is conducive to ensuring the stability of locking the second rod body 212; at the same time, the setting of the limiting gasket 233 can also effectively prevent the locking bolt 232 from falling off and causing the loss of parts.

[0073] In this embodiment, the correction mechanism 2 is arranged on the seat body 1 through the first rod 211. Figure 8 , a connection method is shown in FIG. 1 , in which the bottom of the first rod body 211 is arranged on the support seat 131 , and a reinforcing rod 24 is further connected between the first rod body 211 and the cross bar 133 .

[0074] Figure 9 , another connection method is shown in FIG. 1 , in which the bottom of the first rod body 211 is not connected to the support base 131 , but is directly connected to the cross bar 133 through the reinforcing rod 24 on one side thereof.

[0075] Of course, the bottom of the first rod 211 may be directly connected to the support base 131 , and the first rod 211 and the cross bar 133 may not be provided with the reinforcing rod 24 .

[0076] In summary, in this embodiment, the connection method between the correction mechanism 2 and the seat body 1 is not particularly limited. The main purpose is to reduce the amount of material used as much as possible while ensuring the stability of the connection, so as to further reduce the manufacturing cost.

[0077] Example 3

[0078] This embodiment is another embodiment of the correction mechanism 2.

[0079] refer to Figure 5 、 Figure 6 、 Figure 7 As shown, the telescopic member 21 includes a first rod 211 and a second rod 212 that are sleeved together. The first rod 211 is sleeved on the second rod 212, and the two rods are locked and released by a locking assembly 23.

[0080] The locking assembly 23 includes a group of limit rods 234 cross-hinged and arranged in the telescopic member 21, one end of the limit rod 234 is connected to the starting block 235 located outside the second rod body 212 through a connecting rod, and the other end extends into the first rod body 211 and is connected to the limit part 236.

[0081] The start block 235 is slidably mounted on the lower end surface of the stop block 22, and the two start blocks 235 are connected by an elastic member 238. The first rod 211 is provided with a space for the stopper 236 to engage. Of course, the second rod 212 is provided with a slot for the connecting rod to slide.

[0082] Preferably, the elastic member 238 is a spring.

[0083] In this embodiment, as an implementation method of the limiting space, the first rod body 211 is provided with a series of limiting holes along its length direction, and each mounting hole forms a limiting space.

[0084] Although the limiting hole can complete the limiting of the limiting portion 236 and complete the locking operation between the two rods, the locking position between the limiting portion 236 and the corresponding limiting hole requires a high precision requirement.

[0085] To this end, the limiting space in this embodiment can adopt another implementation method.

[0086] refer to Figure 7 As shown, the inner wall of the first rod body 211 is provided with a plurality of limiting blocks 237 along its length direction, and the limiting space is formed between adjacent limiting blocks 237 .

[0087] Furthermore, the limit block 237 is a limit ring arranged on the inner wall of the first rod body 211, and the outer end faces of the limit ring and the limit portion 236 are both arc-shaped or conical, or other shapes, to ensure that the limit portion 236 can be more smoothly inserted into the limit space.

[0088] Preferably, the limiting portion 236 is truncated cone-shaped as a whole, with the diameter of the smaller diameter end of the truncated cone being D1 and the diameter of the larger diameter end being D2. D2 is 2-6 times greater than D1. Furthermore, the spacing between two adjacent limiting blocks 237 is between D1 and D2. This design ensures that the limiting portion 236 can be smoothly inserted between the two limiting blocks 237, while also allowing the two sides of the limiting block 237 to collide with the corresponding limiting blocks 237 after insertion, thereby ensuring the stability of the limiting block 237 during the locking process.

[0089] In a sitting posture correction chair of this embodiment, when the height of the telescopic part 21 needs to be adjusted, the two starting blocks 235 are held by hand and brought closer to each other, so that the two limiting parts 236 at the bottom are close to each other and leave the original limiting space; at this time, the locking relationship between the two rods is released, and the spring is in a compressed state.

[0090] Move the second rod 212 to the desired height and then release it; under the action of the spring restoring force, the two limiting parts 236 move away from each other and are locked into the corresponding limiting spaces, thereby completing the locking operation between the two rods.

[0091] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
