DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 7 As shown:

[0023] Embodiment 1: The utility model provides a table and chair for the deaf-mute with an alarm device, comprising: a table and chair mechanism 1, comprising a table and chair body 11, a button 12 installed on the outside of the table and chair body 11, a warning component 13 fixedly installed on the upper side of the table and chair body 11, and a slide rail 14 arranged on the table and chair body 11; a writing mechanism 2, comprising a support frame component 21 slidably embedded on the slide rail 14, and a flat plate 22 arranged on the support frame component 21; a positioning mechanism 3 installed inside the table and chair body 11, and the positioning mechanism 3 can position the support frame component 21;

[0024] When in use, the warning component 13 can be activated by pressing the button 12 to alert other people. When the tablet 22 needs to be used, the support frame component 21 is moved close to the user. When the support frame component 21 is against the positioning mechanism 3, it will be fixed by the positioning mechanism 3, so as to facilitate the user to use it. After use, the positioning mechanism 3 releases the limit of the support frame component 21, and then the support frame component 21 is slid away from the user, which can facilitate the user to place books for study.

[0025] Specifically, the warning component 13 includes a support frame 131 , to which a warning bell 132 and a warning light 133 are fixedly connected; the button 12 and the warning bell 132 are electrically connected, and the button 12 and the warning light 133 are electrically connected.

[0026] Specifically, the support frame assembly 21 includes a slider 211 and a limiting frame 212 . The outer side of the slider 211 is fixedly connected with a rotating shaft 213 , and the bottom of the limiting frame 212 is fixedly connected with an axis hole frame 214 .

[0027] Specifically, the limiting frame 212 is embedded on the rotating shaft 213 through the shaft hole frame 214 for damping rotation, the slider 211 is embedded on the slide rail 14 for limiting sliding, and the flat plate 22 can be embedded on the limiting frame 212 .

[0028] As can be seen from the above, after pressing the button 12, the warning bell 132 and the warning light 133 will work together, thereby reminding nearby people to pay attention. The tablet 22 is placed on the limit frame 212. After the limit frame 212 is rotated around the slider 211 to a suitable angle, the tablet 22 can be used more conveniently. The slider 211 is slid to a specified position on the slide rail 14, which can facilitate the user to use the tablet 22.

[0029] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the bottom of the slider 211 is also fixedly connected to an external bracket 215, a positioning block 216 is fixedly connected to the external bracket 215, and a trapezoidal slot 217 is also provided at the bottom of the positioning block 216; the positioning mechanism 3 includes a positioning frame 31, a connecting rod 32 and a spring 33, the upper end of the positioning frame 31 is fixedly connected to a positioning plate 34, the upper end of the connecting rod 32 is fixedly connected to a trapezoidal positioning block 35, the lower end of the connecting rod 32 is fixedly connected to a handle 36, and the outer side of the connecting rod 32 is also fixedly connected to a limiting ring 37.

[0030] Specifically, the positioning frame 31 is fixedly installed inside the table and chair body 11 through the positioning plate 34, the spring 33 is sleeved on the outside of the connecting rod 32, the connecting rod 32 is limited and slidably embedded in the bottom of the positioning frame 31, the spring 33 drives the limiting ring 37 to drive the connecting rod 32 to move upward, and the trapezoidal positioning block 35 can be embedded in the trapezoidal slot 217.

[0031] As can be seen from the above, when the slider 211 slides and the positioning block 216 is inserted into the positioning frame 31, the trapezoidal positioning block 35 will be embedded in the trapezoidal slot 217, thereby limiting the movement of the slider 211. At this time, the user can use the tablet 22 more stably. When the lock needs to be released, pulling the handle 36 downward can make the connecting rod 32 drive the trapezoidal positioning block 35 to move downward and disengage from the trapezoidal slot 217, so that the slider 211 can slide away from the user again. At the same time, when the trapezoidal positioning block 35 moves downward, the limiting ring 37 will also drive the spring 33 to be compressed on the positioning frame 31. When the slider 211 is removed, the spring 33 will reset after releasing the handle 36, which will cause the limiting ring 37 to drive the connecting rod 32 and the trapezoidal positioning block 35 to move upward, thereby facilitating positioning and use next time.
