Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools for decoration engineering, and particularly relates to a straightedge corrector. Background Art

[0002] At present, in decoration projects, it is often necessary to use a straightedge to detect the perpendicularity of the decorative surface, and the perpendicularity of the straightedge is usually corrected using an infrared level. The method is as follows: First, use the infrared level to project a vertical light on a flat wall surface. Hold the straightedge against the wall surface and align it with the light, and check whether the pointer returns to zero. If it does not return to zero, use a screwdriver for mechanical zero adjustment to correct it.

[0003] However, in the above method, it mainly relies on the infrared level, and there are the following drawbacks:

[0004] (1) Environmental limitations: In a strong sunlight or bright light environment, the infrared rays may not be easily visible, affecting the accuracy;

[0005] (2) Equipment cost: Infrared levels are usually more expensive than traditional tools and are easily worn out, increasing the project cost;

[0006] (3) Difficulty in leveling: The infrared level itself needs to be leveled. If the ground is uneven or the leveling is not in place, the level may not reach a completely horizontal state, resulting in a deviation of the projected laser line;

[0007] Based on this, it is necessary to research a straightedge corrector. Content of the Utility Model

[0008] In view of this, the purpose of the utility model is to provide a straightedge corrector, which can effectively solve the problems of being limited by environmental conditions, cumbersome operation, and high equipment cost when using an infrared level to correct a straightedge.

[0009] To achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A straightedge corrector includes an upper fixing member, a lower fixing member, a hanging wire, and a plumb bob;

[0011] The upper fixing member includes an upper fixing portion, an upper cantilever, and an upper positioning portion;

[0012] The upper cantilever is vertically and fixedly connected to the upper fixing portion and extends horizontally to the right. The upper positioning portion is vertically fixed on the lower surface of the upper cantilever;

[0013] The lower fixing member includes a lower fixing portion, a lower cantilever, and a positioning slider;

[0014] The lower cantilever is vertically and fixedly connected to the lower fixing part and is parallel to the upper cantilever. A chute is formed in the middle of the lower cantilever, which runs through from left to right and from top to bottom.

[0015] The positioning slider is vertically slidably arranged on the upper end surface of the lower cantilever through the chute.

[0016] The upper end of the suspension line is fixedly connected to the upper fixing part and contacts the upper positioning part. The lower end of the suspension line passes through the chute and is fixedly connected with a plumb bob.

[0017] When the positioning slider moves to the position where it contacts the suspension line, a correction calibration area is formed among the upper cantilever, the lower cantilever, the upper positioning part and the positioning slider.

[0018] Further, a wire post is arranged on the upper surface of the upper cantilever, and a wire passing hole is formed in the upper cantilever. The wire passing holes are distributed above the upper positioning part, and the suspension line passes through the wire passing holes and contacts the upper positioning part.

[0019] Further, the wire post is located on the right side of the wire passing hole. The wire passing hole is a semi-circular hole, and the right side wall of the wire passing hole is a vertical plane and is in the same plane as the left end face of the upper positioning part, so that the suspension line contacts the left end face of the upper positioning part.

[0020] When the inner surface of the positioning slider contacts the suspension line, the left end face of the positioning slider and the left end face of the upper positioning part are in the same vertical plane.

[0021] Further, the wire post is a bolt, and a threaded hole is formed in the upper cantilever. The wire post is threadedly connected to the upper cantilever through the threaded hole.

[0022] Further, the positioning slider includes a lower positioning part, a slider part and a locking part. The slider part is slidably arranged in the chute. The lower positioning part is vertically fixed above the sliding part. The locking part is fixed on the side wall of the lower positioning part and extends to the side wall of the lower cantilever. A setscrew is threadedly connected to the locking part, and the setscrew abuts against the side wall of the lower cantilever to lock the positioning slider.

[0023] Further, a support frame is also included. The support frames are arranged vertically. The upper fixing part and the lower fixing part are both provided with fixing holes, and the upper fixing part and the lower fixing part are both fixedly connected to the support frame through the fixing holes.

[0024] Further, the support frame is a telescopic frame, including an upper frame and a lower frame. The upper frame is slidably sleeved in the lower frame and is locked by a fastening screw. The upper fixing part is fixedly connected to the upper frame, and the lower fixing part is fixedly connected to the lower frame.

[0025] The beneficial effects of the above technical solutions are:

[0026] The utility model obtains a vertical plumb line by using a suspension line and a plumb bob. The upper end of the plumb line contacts the upper positioning part of the upper fixing part. By moving the positioning slider of the lower fixing part to contact the plumb line, two contact points can form a stable vertical calibration plane, so as to form a correction calibration area among the upper cantilever, the lower cantilever, the upper positioning part and the positioning slider, and convert the vertical feature of the plumb line into the geometric position feature in the correction calibration area. By placing the straightedge in the correction calibration area for alignment, the straightedge can be placed vertically and mechanically calibrated without using an infrared level. It can effectively solve the problems of being limited by environmental conditions, cumbersome operation and high equipment cost when using an infrared level to calibrate the straightedge. Compared with using an infrared level, the utility model has low cost, simple operation, flexible use, is not affected by strong light, and can adjust the straightedge to a vertical state more precisely by using the plumb line.

The left and right directions refer to Figure 4 the left and right directions of

[0039] ; the positioning slider 203 is vertically slidably arranged on the upper end surface of the lower cantilever 202 through the chute 204. Damping or friction is provided in the sliding connection so that the positioning slider 203 can slide left and right and stay in a specific position.

[0040] Both the upper fixing part 101 and the lower fixing part 201 are connected to a relatively flat and vertical fixing foundation such as a wall surface, a column, or a cabinet wall. The connection method can be bonding, anchoring, magnetic attraction, etc., so that the upper fixing member 1 and the lower fixing member 2 are arranged up and down. The distance between the upper cantilever 102 and the lower cantilever 202 is two meters, which is used to correct a two-meter-long spirit level. The upper end of the suspension line 3 is fixedly connected to the upper fixing member 1 and contacts the upper positioning part 103. The lower end of the suspension line 3 passes through the chute 204 and is fixedly connected to a plumb bob 4; a line post 5 is arranged on the upper surface of the upper cantilever 102. The line post 5 is mainly used for binding and fixing the upper end of the suspension line 3. The line post 5 is located on the right side of the wire passing hole 104. The line post 5 is a bolt, and a threaded hole is provided on the upper cantilever 102. The line post 5 is threadedly connected to the upper cantilever 102 through the threaded hole. In other embodiments, the line post 5 may not be provided, and the upper end of the suspension line 3 may be directly fixed to the upper positioning part 103 to achieve the contact between the suspension line 3 and the upper positioning part 103.

After the suspension wire 3 and the plumb bob 4 are stable, move the positioning slider 203 until its left end face contacts the suspension wire 3, and tighten the setscrew 6 to fix the positioning slider 203. Then hold the leveling rod by hand, and use the geometric position features in the correction calibration area as a reference to vertically align the leveling rod, so that the upper and lower ends of the leveling rod are respectively attached to the right end faces of the upper positioning portion 103 and the positioning slider 203. When the leveling rod and the suspension wire 3 are parallel, the leveling rod is in the vertical position. Finally, correct and zero the leveling rod.
