Detailed ways

As shown in Figures 1 and 2, the utility model is mainly composed of a mobile frame 1, a fixed frame 2, and an operating mechanism 3, wherein the mobile frame 1 and the fixed frame 2 are configured in an overlapping manner, and the fixed frame 2 is fixed at a predetermined position of the chair 4 and does not move. The moving frame 1 is used to engage with the bottom surface of the seat 40 of the chair 4. It forms a cooperative relationship with the fixed frame 2 so that it can move in the fixed frame 2. Change to the position, and be positioned by the driving of the operating mechanism 3 and the interference between the fixed frame 2 and the moving frame 1; wherein,

The surface 10 of the mobile frame 1 is provided with a plurality of positioning holes 11 for fixed connection with the seat portion 40 of the chair 4. It has at least two opposite sides and respectively forms a frame groove 12, 13 for corresponding to the fixed frame 2, and wherein A frame slot 12 is provided with an operation hole 14 for the operation mechanism 3 to intervene;

The fixed frame 2 has at least two opposite sides 20, 21 which are contained by the frame grooves 12, 13 of the aforementioned mobile frame 1, and a plurality of slide blocks 22 are connected outside it to facilitate relative movement with the mobile frame 1, and wherein One side 20 has several tooth grooves 24 formed by several tooth portions 23 at intervals;

The operating mechanism 3 is a crank, at least has an operating end 30 and an operating end 31, which is attached to the outer side of the frame groove 12 provided with the operating hole 14 of the aforementioned mobile frame 1, and the end of the operating end 30 forms an oblique The cut surface 301 extends into the operation hole 14 and falls on one of the tooth slots 24 of the fixed frame 2. As for the operation end 31, it is used to drive the oblique cut surface 301 to rotate. The spring 32 forms a link to increase its rotational torque.

When assembling, first fix the fixed frame 2 at the predetermined position of the chair 4, and then use the mobile frame 1 connected with the seat 40 to pass through the frame grooves 12, 13 to contain the fixed frame 2, so that the mobile frame 1 is subjected to an external force relative to the The fixed frame 2 moves axially;

In addition, at least one set of tension springs 5 can be added between the mobile frame 1 and the fixed frame 2. As shown in FIG. , the other end 51 is fixed on the fixed frame 2, so that the moving frame 1 is pulled by the spring 5 when it moves relative to the fixed frame 2, and tends to be more stable.

As shown in FIG. 3 , the active end 30 of the operating mechanism 3 is in a normal state against the bottom 241 of the tooth groove 24 with its beveled surface 301 , so that the active end 30 interferes with the movable frame 1 and the fixed frame 2 . The moving frame 1 cannot be moved by an external force; on the contrary, as shown in Figure 4, when the operating end 31 is subjected to an external force action, it will drive the acting end 30 to rotate and break away from the interference with the tooth groove 24, and the moving frame 1 will be The axial position can be changed relative to the fixed frame 2 until the active end 30 falls into the other tooth groove 25 .

In the above, by means of the action end 30 of the operating mechanism 3, under the normal state (that is, when the position of the seat is fixed), the torsion force generated by the torsion spring 32 through the torsion spring 32 with its oblique surface 301 is against the bottom surface 241 of the tooth groove 24, which will make the fixed frame 2 The matching relationship with the mobile frame 1 is tighter, that is, the seat position 40 of the chair 4 is less likely to shake after being fixed, and compared with the previous technology disclosed earlier, the interference method of the bolt and the positioning hole is more effective. Progress and practicality.

To sum up, it can be seen that the utility model should meet the requirements of the patent law, but the description and related drawings are only preferred embodiments of the utility model, and are not used to limit the scope of implementation of the utility model, that is, All equivalent changes and modifications made according to the content of the patent scope of the utility model shall be within the technical scope of the utility model, and shall be limited by the following requirements of the scope of the patent application.
