DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: a folding escort chair, including a seat bracket 100, a folding seat 200 rotatably connected to the seat bracket 100, and an anti-theft lock 300 installed on the seat bracket 100 for limiting the folding bracket;

[0026] The seat bracket 100 includes two groups of support side plates 101 and a limit connection beam 105. The two ends of the limit connection beam 105 are respectively fixedly connected to the lower ends of the two groups of support side plates 101 on the opposite side. A fixed support beam 106 is fixedly connected to the upper ends of the two groups of support side plates 101 on the opposite side. Two groups of connection hinges 107 are fixedly connected to one side of the fixed support beam 106. Support feet 103 are fixedly connected to the upper ends of the two groups of support side plates 101 on the opposite side. A limit card slot 104 is provided on the upper surface of the support foot 103;

[0027] The folding seat 200 includes a third bottom frame 205. Limit blocks 212 are symmetrically and fixedly connected to the lower surface of the third bottom frame 205. The limit blocks 212 are triangularly arranged. The support feet 103 and the fixed support beam 106 are used to improve the stability of the support for the unfolded folding seat 200.

[0028] The folding seat 200 further includes a first bottom frame 201 and a second bottom frame 202. The first bottom frame 201 is rotatably connected to the two groups of connection hinges 107. First connecting plates 203 are rotatably connected to both sides of the second bottom frame 202. Second connecting plates 204 rotatably connected to the first connecting plates 203 are rotatably connected to both sides of the third bottom frame 205. One end of the first bottom frame 201 is hinged to one end of the second bottom frame 202. The first bottom frame 201 is hinged to the second bottom frame 202 by a hinge to facilitate the unfolding of the first bottom frame 201 and the second bottom frame 202 when the position of the third bottom frame 205 moves.

[0029] A first cushion plate 206 is detachably connected to the upper surface of the first bottom frame 201. A head cushion plate is provided on one side of the first cushion plate 206. A second cushion plate 207 is detachably connected to one side of the second bottom frame 202. A third cushion plate 208 is detachably connected to one side of the third bottom frame 205. The detachable structure can detach the backrest and the pillow seat plate, and can also detach the overall frame, saving freight, being convenient for on-site operation and maintenance assembly, and facilitating the replacement of the thickness and material of the cushion plate.

[0030] A support frame 209 is fixedly connected to the lower surface of the third bottom frame 205. One end of the support frame 209 is arranged below the limit connection beam 105. Multiple groups of moving wheels 210 are detachably connected to the lower end of the support frame 209. The moving wheels 210 are used to facilitate the stability of the movement of the support frame 209 on the third bottom frame 205, and the moving wheels 210 are silent wheels, reducing the noise during unfolding. The overall structure is simple, improving the practicality.

[0031] On the opposite sides of the two groups of supporting side plates 101, guiding grooves 109 are respectively formed. A movable supporting beam 108 is detachably connected in the two groups of guiding grooves 109. The movable supporting beam 108 and the fixed supporting beam 106 are arranged in the same plane. At one end of the upper surfaces of the two groups of supporting side plates 101, armrests 102 are respectively arranged. The guiding grooves 109 are used to conveniently adjust the position of the movable supporting beam 108, thereby improving the stability of the folding seat 200 after it is unfolded. The comfort of the accompanying personnel sitting on the folding seat 200 is increased through the armrests 102.

[0032] At the corners of the opposite sides of the two groups of supporting side plates 101, casters 110 are respectively arranged. Anti-slip pads are arranged on the lower surfaces of the two groups of supporting side plates 101. On one side of one group of supporting side plates 101, a side groove 111 for installing the anti-theft lock 300 is formed. The casters 110 are used to conveniently move the whole accompanying chair without manual handling, improving the moving convenience of the accompanying chair.

[0033] The anti-theft lock 300 includes a lock body 301 installed in the side groove 111. A battery cover 302 is detachably connected to one side of the lock body 301. An anti-theft steel bar lock hole 303 is formed on the side of the lock body 301 adjacent to the battery cover 302. An operation panel 211 is arranged on one side of the support frame 209, and a steel bar chain inserted into the anti-theft steel bar lock hole 303 is fixedly connected to one side of the operation panel 211. The anti-theft lock 300 is convenient for people to unlock when in use, avoiding misuse by accompanying personnel. Moreover, the anti-theft lock 300 has concealed wiring, greatly reducing the probability of damage, improving the utilization rate, having a large battery space, convenient battery replacement, and reducing the operation and maintenance times and costs.

[0034] When the caregiver does not lie down for accompanying, the caregiver can directly sit on the accompanying chair to perform the accompanying work. When the caregiver needs to lie down for accompanying, first operate according to the operation steps on the operation panel 211, so that the end of the steel bar chain disengages from the anti-theft steel bar lock hole 303, in order to release the locking of the folding seat 200. First, lift the first bottom frame 201 upward, and then the limit block 212 on the first bottom frame 201 disengages from the limit card slot 104 of the support foot 103. At the same time, under the limiting action of the limit connecting beam 105, the first bottom frame 201 is prevented from being lifted too high. After the first bottom frame 201 is lifted, pull it outwards, so that the second connecting plate 204 drives the first connecting plate 203 to flip. At the same time, the inclination angle between the first bottom frame 201 and the second bottom frame 202 changes. The first bottom frame 201 rotates around the connecting hinge 107 as the axis. When the first bottom frame 201, the second bottom frame 202 and the third bottom frame 205 are all in the same plane, the unfolding of the folding seat 200 is completed, and the first bottom frame 201 is located above the fixed support beam 106 and the movable support beam 108. At the same time, the second bottom frame 202 is located on the support foot 103, which improves the stability of the support, so that the caregiver can lie on the unfolded folding seat 200 for accompanying, improving the comfort of the accompanying personnel. And the accompanying chair makes less noise when unfolding and storing, thus creating a quiet accompanying environment and improving the practicability.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
