[0030] First embodiment:

[0031] like Figure 1-Figure 12 As shown, a sitting posture corrector includes a pad 1, a connecting portion 3, and a supporting portion 2. The pad 1 is provided with a table edge 101 on one side, and the table edge 101 is provided with a socket 102 for inserting the connecting portion 3. One end of the connecting portion 3 is fixedly connected to the pad 1 through a magnetic suction component, and the other end is connected to the supporting portion 2. The supporting portion 2 is used to support the human body in front.

[0032] The magnetic attraction component includes a first magnetic attraction component 301 fixedly connected to the lower end of the connecting part 3 and a second magnetic attraction component 103 fixedly connected to the pad 1 and located in the socket 102 or at the bottom of the socket 102; the first magnetic attraction component 301 is a magnet, and the second magnetic attraction component 103 is a magnetic material.

[0033] The first magnetic member 301 is attracted to the second magnetic member 103 by magnetic force, so that the connecting portion 3 is fixedly connected to the table edge portion 101. Figure 2 As shown, when it is necessary to switch to the hidden state, pull the connecting part 3 upward to disengage the connecting part 3 and the socket 102, then make the supporting part 2 face the table, and move the first magnetic component 301 close to the lower surface of the second magnetic component 103. The first magnetic component 301 is attracted to the second magnetic component 103 by magnetic force, so that the supporting part 2 is hidden under the table and will not affect people's activities on the table.

[0034] The connecting portion 3 is provided with a plurality of guide ribs 302, and the inserting hole 102 is provided with corresponding guide grooves 104. The guide ribs 302 not only play a guiding role, but also enhance the stability of the connection between the connecting portion 3 and the table edge portion 101.

[0035] The connecting portion 3 includes a first outer tube 311 , in which a first inner tube 312 is sleeved. The first inner tube 312 can move axially in the first outer tube 311 . A first limiting mechanism is provided between the first outer tube 311 and the first inner tube 312 , and the first limiting mechanism is used to limit the movement of the first inner tube 312 .

[0036] The first limiting mechanism includes a first rack 313 arranged axially on the first inner tube 312 and a locking part 314 arranged on the first outer tube 311. One end of the locking part 314 is provided with a latch tooth 315 corresponding to the first rack 313, and the other end is provided with a pressing part 316. The locking part 314 is hinged to the first outer tube 311 through a first rotating shaft 317 arranged between the latch tooth 315 and the pressing part 316, and a spring 318 is provided between the pressing part 316 and the first outer tube 311.

[0037] The tooth shape of the first rack 313 is low at the top and high at the bottom, so that the first inner tube 312 is easy to pull up and will not move when pressed down. When the position of the first inner tube 312 needs to be adjusted, one hand presses on the pressing part 316 to disengage the latching teeth 315 from the first rack 313, and the other hand moves the first inner tube 312 up and down to the required height, and then releases the pressing part 316. Due to the action of the spring 318, the latching teeth 315 abut against the first rack 313 again, and the first inner tube 312 is limited.

[0038] The first inner tube 312 is also provided with a first sliding groove 319 in the axial direction, and the first outer tube 311 is provided with a first pin shaft 320, which is located in the first sliding groove 319. When the first inner tube 312 moves upward to the upper limit position, the first pin shaft 320 abuts against the bottom end of the first sliding groove 319. The first pin shaft 320 can prevent the first inner tube 312 from being completely pulled out when the first inner tube 312 is pulled upward.

[0039] A second outer tube 321 is provided on the first inner tube 312. The second outer tube 321 is sleeved with a second inner tube 322. The second inner tube 322 can move axially in the second outer tube 321. A second limiting mechanism is provided between the second outer tube 321 and the second inner tube 322. The second limiting mechanism is used to limit the movement of the second inner tube 322.

[0040] The second limiting mechanism can use the same structure as the first limiting mechanism, or can use other conventional limiting structures such as screw rod tightening, pin hole matching, etc. Similarly, a second pin shaft is also provided to prevent the second inner tube 322 from being completely pulled out.

[0041] The support portion 2 includes two support blocks 201 and a bracket component 202. The bracket component 202 is used to connect the connection portion 3 and the support block 201. The distance between the two support blocks 201 can be adjusted in the left-right direction.

[0042] The support block 201 is connected to the bracket component 202 via a buckle 203. The buckle 203 is provided with a convex tooth portion 204, and the bracket component 202 is provided with a corresponding tooth groove 205. The convex tooth portion 204 is clamped in the tooth groove 205 to limit the sliding of the support block 201.

[0043] The support block 201 includes a soft pad 206, a middle plate 207, and a bottom plate 208 which are connected in sequence. The soft pad 206 can be made of soft materials such as silica gel to improve the comfort of use.

[0044] Second embodiment:

[0045] The second embodiment is different from the first embodiment in that the first magnetic attraction member 301 is made of magnetic material, and the second magnetic attraction member 103 is a magnet.

[0046] Third embodiment:

[0047] like Fig.13 As shown, the difference between the third embodiment and the first embodiment is that the magnetic attraction component includes a first magnetic attraction member 301 fixedly connected to the lower end of the connecting portion 3, and a third magnetic attraction member 105 and a fourth magnetic attraction member 106 fixedly connected to the pad 1 and located in the socket 102 or at the bottom of the socket 102. The first magnetic attraction member 301, the third magnetic attraction member 105 and the fourth magnetic attraction member 106 are all magnets, and the outward pole of the third magnetic attraction member 105 and the fourth magnetic attraction member 106 is the opposite pole of the outward pole of the first magnetic attraction member 301. By setting the structure of magnet attracting magnet, compared with the structure of the first embodiment, the magnetic force is stronger and the adsorption is more firm.

[0048] Fourth embodiment:

[0049] like Fig.14As shown, the fourth embodiment is different from the first embodiment in that: the connection part 3 is fixedly connected to the pad 1 through a mechanical connection component, the mechanical connection component includes a pin 107, the connection part is provided with a first through hole 108, a partition 109 is provided in the socket, and a second through hole 110 and a third through hole 111 corresponding to the first through hole are provided above and below the partition, respectively. When in use, the pin 107 passes through the first through hole 108 and the second through hole 110 to fix the connection part 3 and the pad 1. When it is necessary to switch to a hidden state, the pin 107 is first pulled out, and then the connection part 3 is pulled out upward from the socket 102, and then the support part 2 is facing the table, and the connection part 3 is inserted into the socket 102 from the bottom, and the pin 107 passes through the first through hole 108 and the third through hole 111 to fix the connection part 3 and the pad 1. The mechanical connection component can also adopt conventional structures such as snap-fit ​​components, which will not be described here.

[0050] The above shows and describes the basic principle, main features and advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, simple changes and substitutions by ordinary technicians in this field are within the protection scope of the utility model.
