the unlocking piece comprises a second conical block 22, a fixed ring 23 and a second resetting piece, wherein the second conical block 22 is movably sleeved on the sliding rod 13, the maximum radius of the second conical block 22 is smaller than or equal to the maximum distance between the inclined surface and the axis of the first hole 9, the maximum diameter of the second conical block 22 is larger than or equal to the maximum diameter of the first conical block 14, the tip of the second conical block 22 is arranged back to the first conical block 14, the second conical block 22 is arranged between the first conical block 14 and the fixed ring 23, the fixed ring 23 is fixedly connected with the sliding rod 13, the second conical block 22 and the fixed ring 23 are provided with the second resetting piece, the second resetting piece is used for driving the second conical block 22 to move towards the direction of the fixed ring 23, and the second resetting piece is arranged to separate the first conical block 14 from the second conical block 22 after unlocking, so that the phenomenon that a sliding fan 8 cannot be locked with the frame body 1 in the later period is effectively avoided.
The second locking unit 4 further comprises a second through hole 24 and two second connecting rods 25, the second through hole 24 is communicated with the third hole 12 and is vertically arranged, the second connecting rods 25 are connected in a sliding mode in the second through hole 24, the two second connecting rods 25 are respectively arranged on the front side and the rear side of the sliding rod 13, and the two second connecting rods 25 are fixedly connected with one end, far away from the first hole 9, of the sliding rod 13.
When locked, the conical bottom surface of the first conical block 14 and the clamping block 11 are in clearance fit or transition fit.
The unlocking process of the clearance fit between the conical bottom surface of the first conical block 14 and the clamping block 11 is as follows: the staff utilizes slide bar 13 to drive second toper piece 22 to move left for fixture block 11 gradually along deviating from the axial direction of first hole 9 removal, continues to utilize slide bar 13 to make second toper piece 22 and first toper piece 14 butt, moves sliding sash 8 to the left simultaneously, can release the locking between sliding sash 8 and the framework 1.
The unlocking process of the transition fit of the position relationship between the conical bottom surface of the first conical block 14 and the clamping block 11 is as follows: the staff drives the second conical block 22 to move leftwards by utilizing the sliding rod 13, so that the clamping block 11 gradually moves along the axial direction deviating from the first hole 9, the second conical block 22 is abutted against the first conical block 14 by utilizing the sliding rod 13 continuously, and the process needs to ensure that the acting force, applied by the clamping block 11 to the second conical block 22 along the direction of the sliding rod 13, is larger than the acting force, applied by the second reset piece to the second conical block 22 along the direction of the sliding rod 13. The locking between the sliding fan 8 and the frame body 1 can be released by only moving the sliding fan 8 leftwards by a worker, and the operation process can be realized by step operation without synchronous operation in the unlocking process.
Preferably, the second reset element comprises at least one of:
mode one: the second reset piece is a second stretching spring (not shown in the figure), the tip of the second conical block 22 is connected with one end of the second stretching spring, and the side wall of the fixed ring 23 close to the second conical block 22 is connected with the other end of the second stretching spring;
mode two: the second reset piece is a third magnet 26 and a fourth magnet 27, the tip of the second conical block 22 is embedded with the third magnet 26, the side wall of the fixed ring 23 close to the second conical block 22 is embedded with the fourth magnet 27, and the magnetic poles of the third magnet 26 and the opposite surface of the fourth magnet 27 are opposite.
Preferably, the third hole 12 is a first stepped hole, a small hole of the first stepped hole is slidably connected with the slide rod 13, the small hole of the first stepped hole is communicated with the second through hole 24, the axle center of the small hole of the first stepped hole is perpendicular to the central line of the second through hole 24, a large hole of the first stepped hole is arranged towards the first hole 9, a second conical block 22 and a fixed ring 23 are arranged in the large hole of the first stepped hole, one end of a third tension spring 28 is connected to the side wall of the large hole of the first stepped hole far away from the fixed ring 23, and the other end of the third tension spring 28 is connected with the fixed ring 23. The third tension spring 28 is provided to assist the return of the slide bar 13 to the original state after unlocking.
