Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to a wall vertical calibration device. Background Art

[0002] During the construction process of building walls, it is necessary to check the verticality of the walls to prevent the walls from tilting and affecting subsequent use functions.

[0003] For example, a verticality detection device for a building wall proposed in the publication (announcement) No. CN213209064U has a good limiting effect through the setting of a gear ring. The user pulls the pull rod, and the pull rod drives the card block to move along the movable groove. The pull rod drives the fixing plate to move upward, compresses the fixing spring, and the fixing plate is disengaged from the gear, so that the winding rod can rotate. The detection line is paid out downward under the action of the weight block. When the line is paid out to the moving position, the user releases the pull rod, and the fixing plate returns to its original position under the action of the fixing spring, so that the fixing plate is engaged with the gear to prevent the winding rod from rotating and affecting the use effect. When winding the line, the user pulls the pull rod, and the pull rod drives the card block to move out of the movable groove. The user rotates the pull rod so that the card block is engaged with the slot, thereby facilitating the limiting of the fixing plate. The user drives the winding rod to rotate by rotating the handle, so as to facilitate winding up the detection line.

[0004] However, there are still deficiencies in the management and maintenance of the cords, especially the automatic recovery mechanism of the cords often ignores the problem of uniform force on the cords during the winding process. Improper winding methods can easily cause the cords to twist and knot during storage, which not only affects the convenience of next use, but also causes premature aging due to the accumulation of internal stress, shortening the service life.

[0005] In this regard, the present application proposes a wall vertical calibration device to solve this problem. Summary of the invention

[0030] One end of the shaft 201 is connected to one end of the driving gear 204. The shaft 201 is provided with a motor 206. The output end of the motor 206 is connected to the shaft 201. The motor 206 is installed at one end of the bracket 1. The shaft 201 is driven by the motor 206 to reel in or reel out the line.

[0031] The cord 203 is made of nylon, has high toughness and is not easily damaged.

[0032] Further, such as Figures 5 and 6 As shown, in order to link the movement of the winding part and guide the wire rope during winding, a guide part is provided in the present application, and the guide part 3 includes a reciprocating screw rod 301, a driven gear 302, an inner ratchet 303, a pawl 304 and a slider 305, wherein the driven gear 302 is meshed with the driving gear 204, a transmission plate 306 is installed at one end of the reciprocating screw rod 301, and one end of the transmission plate 306 is installed at one end of the inner ratchet 303, and a ring is provided on the driven gear 302. The groove has its interior rotatably connected to the outside of the inner ratchet 303, a connecting rod is installed at one end of the driven gear 302, the pawl 304 is rotatably set on the connecting rod, a spring plate is arranged on one side of the pawl 304, one end of the spring plate is installed at one end of the driven gear 302, the slider 305 is threadedly set on the reciprocating screw rod 301, and a through hole 307 is opened at one end of the slider 305, the through hole 307 has a smooth inner wall, and the through hole 307 is in sliding contact with the rope 203.

[0033] The installation of the spring plate supports the pawl 304 so that the pawl 304 is always matched with the ratchet teeth of the inner ratchet wheel 303 .

[0034] Furthermore, the bracket 1 is concave as a whole, and a first connecting hole is opened on both sides thereof, and the internal rotation of the first connecting hole is set on the shaft rod 201. Second connecting holes are opened on both sides of the bracket 1, which are located below the first connecting hole, and the internal rotation of the first connecting hole is set on the reciprocating screw rod 301.

[0035] The installation of the limiting rod 4 limits the movement trajectory of the slider 305, so that the movement trajectory of the slider 305 is always maintained in a horizontal straight line.

[0036] A wall vertical calibration device, the working principle is as follows:

[0037] When in use, the shaft 201 is driven to rotate by the motor 206, and the shaft 201 drives the bobbin 202 to rotate, so as to release the line 203. The line 203 is always kept taut under the gravity of the plumb bob 205, and the plumb bob 205 and the line 203 are moved downward to the position to be detected. In this process, the shaft 201 synchronously drives the driving gear 204 to rotate, and the driving gear 204 drives the driven gear 302 meshing therewith to rotate, and drives the pawl 304 to move. However, under the installation direction of the inner ratchet 303 and the pawl 304, this rotation direction does not drive the inner ratchet 303 to rotate;

[0038] After use, the motor 206 drives the shaft 201 to reverse, drives the bobbin 202 to move, drives the wire rope 203 to be wound, and the shaft 201 synchronously drives the driving gear 204 to rotate, the driving gear 204 drives the driven gear 302 to rotate, and the driven gear 302 drives the pawl 304 to move. In this rotation direction, the pawl 304 drives the inner ratchet 303 to rotate, and then drives the reciprocating screw 301 to rotate, drives the slider 305 to reciprocate, and the slider 305 drives the wire rope 203 to move, so that the wire rope 203 is evenly wound.
