Detailed Description

Referring to fig. 1, the utility model discloses an is provided with a desk plate 1 at the front end of a chair armrest 2, the upper side and the front side of the desktop 11 of the desk plate 1 are respectively provided with a pen slot 12 and a handheld device vertical slot 13, and the desk plate 1 is pivoted on a pivot fixing part 21 arranged at the front end of the chair armrest 2, and can perform the actions of rotation, turning and positioning, and the rear end of the chair armrest 2 is connected with a connecting part 22 through pivot fixing, and is connected with a frame body or chair legs of the chair to be fixed on .

In view of the installation method between the table 1 and the chair arm 2, as shown in fig. 2 to 4, pivot slots 210 are formed on the pivot fixing portion 21 at the front end of the chair arm 2, a accommodating space 14 is formed in the corner of the table 1, a pivot hole 17 is formed in the middle of the accommodating space 14, a positioning element 3 with a pivot portion 31 is accommodated in the accommodating space 14, the pivot portion 31 is pivotally disposed in the pivot hole 17, and a top cover 4 is disposed to pass through the positioning element 3 through the fixing element 5 at the same time, so as to lock the positioning element 3 on the pivot fixing portion 21.

The table 1 corresponding to the pivot slot 210 on the pivot fixing part 21 at the front end of the armrest 2 is provided with protruding pivot protruding parts 18 capable of being pivoted into the pivot slot 210, so that the table 1 is pivoted between the positioning element 3 and the pivot fixing part 21, and the table 1 can rotate horizontally, so that the table 1 can be pushed inward to be in a use state or pushed outward to be in an open state.

Furthermore, retractable positioning protrusions 33 with elastic expansion function are disposed at the front end of the positioning element 3, a th positioning groove 151 for the retractable positioning protrusions 33 to be inserted into is disposed at the opposite position of the table 1 in the accommodating space 14 of the table 1 when pushed into the use state, and a second positioning groove 152 for the retractable positioning protrusions 33 to be inserted into is disposed at the opposite position of the table 1 when pushed out to the open state.

The two sides of the positioning element 3 are respectively provided with first abutting portions 321 and second abutting portions 322, and similarly, the stopping portion 162 for the abutting portions 321 to abut against is provided at the opposite position where the table board 1 in the accommodating space 14 of the table board 1 is positioned when the table board 1 is pushed into the use state, and the second abutting portions 162 for the second abutting portions 322 to abut against is provided at the opposite position where the table board 1 is positioned when the table board 1 is pushed out to the open state.

Therefore, by the above-mentioned combination method between the desk board 1 and the chair armrest 2, the desk board 1 can perform the actions as shown in fig. 5 on the chair armrest 2, i.e. when the desk board 1 is pushed inward horizontally to be in the use state, the retractable positioning protrusion 33 on the positioning element 3 is just embedded into the -th positioning groove 151, and simultaneously the abutting portion 321 on the positioning element 3 is just abutted against the -th stopping portion 161 of the desk board 1, so that the desk board 1 will not rotate inward excessively, and the located desk board 1 will not be pushed outward easily.

On the contrary, when the table top 1 is pushed out in the horizontal direction to be in the open state as shown in fig. 6, the retractable positioning protrusion 33 on the positioning element 3 is just inserted into the second positioning groove 152, and the second stopping portion 322 on the positioning element 3 is also just stopped on the second stopping portion 162 of the table top 1, so that the table top 1 is not excessively rotated outwards, and the positioned table top 1 is not easily pushed inwards.
