Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Example (b):
referring to fig. 1-4, the present invention provides a technical solution: a fan air door limiting and adjusting device comprises a fan air inlet pipe 1, an air inlet baffle door 2 and two supports 3, wherein the two supports 3 are arranged on two sides of the fan air inlet pipe 1, sliding grooves are formed in the supports 3, sliding blocks 5 are embedded in the sliding grooves, and the sliding blocks 5 on the two sides are respectively connected with the bottoms of the two sides of the air inlet baffle door 2;
the sliding blocks 5 on the two sides can drive the air inlet baffle door 2 to move upwards or downwards, the upper dead point limit switch and the lower dead point limit switch are arranged inside the support 3, and when the sliding blocks 5 move upwards or downwards, the sliding blocks 5 and the steel wire rope 7 are driven to stop moving the sliding blocks 5 by touching the upper dead point limit switch and the lower dead point limit switch.
The upper side of the sliding block 5 is connected with a lower adjusting screw 10, the upper side of the lower adjusting screw 10 is provided with a frame 11, the upper side and the lower side of the interior of the frame 11 are fixedly welded with adjusting nuts 12, the lower adjusting screw 10 is in threaded connection with the adjusting nut 12 on the lower side, and the adjusting nut 12 on the upper side is in threaded connection with an upper adjusting screw 9;
when the existing steel wire rope 7 is used for a long time, the existing steel wire rope 7 can be stretched and deformed, so that the sliding block 5 is in poor contact with a dead point limit switch when rising to the maximum position (when the length of the initial steel wire rope 7 is set to be completely rolled, the sliding block 5 is in contact with the dead point limit switch; when the steel wire rope 7 is completely released, the sliding block 5 is in contact with the dead point limit switch, and when the steel wire rope 7 is stretched, the sliding block 5 cannot be in contact with the dead point limit switch and the dead point limit switch due to the complete rolling or complete release of the steel wire rope 7), so that a power mechanism continues to operate, and the steel wire rope 7 is replaced or the steel wire rope 7 is disassembled;
according to the scheme, the screw thread directions of the lower adjusting screw 10 and the upper adjusting screw 9 are set to be opposite, so that when the frame 11 drives the adjusting nut 12 to rotate relative to the lower adjusting screw 10 and the upper adjusting screw 9, the lower adjusting screw 10 and the upper adjusting screw 9 move towards the frame 11 simultaneously or the lower adjusting screw 10 and the upper adjusting screw 9 move towards the outside of the frame 11 simultaneously, the effect of adjusting the distance between the sliding block 5 and the steel wire rope 7 is achieved, and the defects of the existing mode are overcome.
Go up adjusting screw 9's upper end welding and have connector link 8, the upside fixedly connected with steel wire rope 7 of connector link 8, the upper end of steel wire rope 7 runs through the top of support 3 and extends to the upside of support 3.
Further, the upper ends of the two brackets 3 are fixedly connected through a transverse support frame 4.
Further, a linear bearing is embedded at the joint of the support 3 and the steel wire rope 7, and the linear bearing is sleeved on the outer wall of the steel wire rope 7.
Further, both sides wall of slider 5 all is connected with anticreep shelves strip 6, and anticreep shelves strip 6 imbeds in the spout for slider 5 can not drop from the spout, as shown in fig. 3, this spout is the cross spout, and slider 5 is located the comparatively wide big space in middle part, and anticreep shelves strip 6 is located the less space in both sides, and the cooperation of anticreep shelves strip 6 and spout makes slider 5 can not drop from the spout.
Furthermore, all horizontal spiro union has set screw on the downside on the lateral wall of frame 11, and set screw extends to the inside of frame 11 and supports on adjusting screw 10 down, the outer wall of last adjusting screw 9, through set screw's setting, prevents to appear not hard up the condition between frame 11 and adjusting screw 10 down, the last adjusting screw 9, when the adjustment, unscrews set screw, can be to preventing to rotate the adjustment between frame 11 and adjusting screw 10 down, the last adjusting screw 9.
The working principle is as follows: the sliding block 5 and the anti-dropping stop bar 6 are pre-installed in a sliding groove in the bracket 3, an upper dead point limit switch and a lower dead point limit switch are respectively installed on the upper side and the lower side in the bracket 3, and the upper dead point limit switch and the lower dead point limit switch are used for cutting off a power supply of a power mechanism for pulling the steel wire rope 7, so that when the sliding block 5 reaches the positions of the upper dead point limit switch and the lower dead point limit switch, the power mechanism does not drive the sliding block 5 to continue moving;
the power mechanism pulls the sliding blocks 5 and the air inlet baffle door 2 between the two sliding blocks 5 to ascend or descend through the steel wire ropes 7, so that the air inlet baffle door 2 adjusts the plugging area of the mouth of the air inlet pipe 1 of the fan;
the frame 11 is rotated, and the frame 11 drives the adjusting nut 12 to rotate relative to the upper adjusting screw 9 and the lower adjusting screw 10, so that the distance between the upper adjusting screw 9 and the lower adjusting screw 10 is adjusted, and the steel wire rope 7 is adjusted.
Having shown and described the basic principles and principal features of the invention and advantages thereof, it will be apparent to those skilled in the art that the invention is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof; the present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
