DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a planar fan as shown in Figures 1-5 which includes a machine head 1. A support rod 2 is provided at the bottom of the machine head 1, and a chassis 3 is provided at the bottom of the support rod 2. It further includes;

[0025] An installation component 4 for replacing the chassis 3. The installation component 4 includes a fixed seat 401 fixedly connected to the bottom end of the chassis 3. A positioning groove 403 is opened at the top end of the fixed seat 401, and a positioning block 402 adapted to the positioning groove 403 is fixedly connected to the bottom end of the support rod 2;

[0026] A limiting component 5 is provided at the connection between the positioning block 402 and the positioning groove 403, and the limiting component 5 is used for installing and disassembling the positioning block 402;

[0027] A strengthening component 6 is provided at the bottom of the support rod 2, and the strengthening component 6 is used to strengthen the connection between the support rod 2 and the chassis 3.

[0028] Specifically, an insertion hole 404 is opened in the middle of the chassis 3, and the positioning block 402 is inserted and connected inside the insertion hole 404, and the insertion hole 404 communicates with the positioning groove 403.

[0029] It should be noted that the provided machine head 1 includes a motor, a fan blade and a mesh cover. During use, the fan blade is driven to rotate by the motor, and the fan is protected by the mesh cover to prevent people from contacting the rotating fan blade; the horizontal cross-section of the opened insertion hole 404 is the same as that of the opened positioning groove 403 and is adapted to the provided positioning block 402, so that the positioning block 402 can penetrate into the positioning groove 403 through the insertion hole 404; when the fan is being carried and the chassis 3 is damaged due to collision, a new chassis 3 is taken out again ， and the positioning block 402 at the bottom of the support rod 2 is inserted into the positioning groove 403 on the fixed seat 401, and the positioning block 402 is restricted inside the positioning groove 403 through the limiting component 5 to complete the fixation of the position of the positioning block 402, and the support rod 2 and the chassis 3 are fixed through the positioning block 402 at the fixed position.

[0030] Specifically, the limiting component 5 includes positioning holes 501 symmetrically opened on the inner walls of both sides of the positioning groove 403. Through slots 504 are symmetrically opened on both sides of the positioning block 402. A clamping block 502 is inserted and connected inside the through slot 504. The clamping block 502 is inserted and connected inside the positioning hole 501. A connecting block 503 is fixedly connected to one side of the clamping block 502. A spring 505 is arranged on one side of the connecting block 503. A cavity 506 is opened on the inner wall of one side of the through slot 504. Both the connecting block 503 and the spring 505 are inserted and connected inside the cavity 506.

[0031] It should be noted that the opened cavity 506 is adapted to the arranged connecting block 503, enabling the connecting block 503 to slide inside the cavity 506. Both ends of the arranged spring 505 are fixedly connected to one side of the connecting block 503 and the inner wall of one side of the cavity 506 respectively. The spring 505 is used to push the connecting block 503 to the side away from the spring 505 and push the connecting block 503 to fit against the inner wall of the other side of the cavity 506. The horizontal longitudinal section of the opened through slot 504 is smaller than the horizontal longitudinal section of the connecting block 503, so that the connecting block 503 cannot pass through the through slot 504 and out of the cavity 506, and the distance of the clamping block 502 is restricted by the connecting block 503 with a limited moving distance. The arranged clamping block 502 is fixedly connected to one side of the connecting block 503, and the moving distance of the clamping block 502 is restricted by the connecting block 503 with a limited moving distance. When the clamping block 502 is moved into the positioning hole 501, one side of the clamping block 502 is still inside the through slot 504, and the movement of the positioning block 402 is restricted by the clamping block 502.

[0032] Specifically, the strengthening component 6 includes a strengthening seat 601 sleeved on the bottom end of the support rod 2. The strengthening seat 601 is arranged on the top end of the chassis 3. Strengthening grooves 603 are symmetrically opened at the center of the top end of the chassis 3. Strengthening blocks 602 are symmetrically and fixedly connected to the center of the bottom end of the strengthening seat 601. The strengthening blocks 602 are inserted and connected inside the strengthening grooves 603.

[0033] It should be noted that the arranged strengthening seat 601 is a frustum of a cone with a through hole in the middle. When needed, the strengthening seat 601 is sleeved on the bottom end of the support rod 2 and fixed to the bottom of the support rod 2 by welding or other means. After the support rod 2 and the chassis 3 are installed, the bottom end of the strengthening seat 601 is made to fit against the top end of the chassis 3. When the support rod 2 tilts to one side, the situation of breakage at the connection between the support rod 2 and the chassis 3 is avoided by the blockage of the strengthening seat 601. The arranged strengthening blocks 602 are inserted and connected inside the strengthening grooves 603, and the connection between the support rod 2 and the chassis 3 is strengthened by the strengthening seat 601.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
