Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a special gap verifying attachment of elevator inspection, including handheld pole 4 and detection main part, it includes first mounting panel 11 and the second mounting panel 12 that the face is parallel to each other to detect the main part, first mounting panel 11 carries out fixed connection through the bolt with second mounting panel 12, forms a measurement activity space between the face of first mounting panel 11 and the face of second mounting panel 12.

Two right-angle trapezoidal sliding blocks 7 and an isosceles right triangle sliding block 6 are arranged in the measuring movable space; a sliding groove 12a is formed in the first mounting plate 11 along the length direction, the acute angles of the two right-angled trapezoidal sliding blocks 7 are 45 degrees, the two right-angled trapezoidal sliding blocks 7 are symmetrically arranged, and the two right-angled trapezoidal sliding blocks 7 are matched in the sliding groove 12a in a sliding mode; every all be equipped with a pressure spring between the edge between right trapezoid slider 7 and the first mounting panel 11, the pressure spring is located in the spout 12a, and the both ends of pressure spring are fixed with right trapezoid slider 7 and first mounting panel 11 respectively.

As shown in fig. 1 and 2, after the second mounting plate 12 and the first mounting plate 11 are detached, the compression spring and the two right-angled trapezoidal sliders 7 can be taken out from the sliding groove 12 a. Thus, the two right-angled trapezoidal sliders 7 are substantially constrained within the slide groove 12a by the second mounting plate 12. This is primarily to facilitate later maintenance and calibration.

The isosceles right triangle slider 6 is positioned between the two right trapezoid sliders 7, and two inclined surfaces of the isosceles right triangle slider 6 are respectively in one-to-one correspondence with and in sliding fit with two inclined surfaces of the two right trapezoid sliders 7; two opposite planes of the isosceles right triangle slider are respectively in sliding fit with the plate surfaces of the first mounting plate 11 and the second mounting plate 12, and a limiting block 9 for preventing the isosceles right triangle slider from falling out of the measuring moving space is further arranged in the measuring moving space; the plate surface of the second mounting plate 12 is provided with a pull groove 11a and scale marks 11b, and the long directions of the pull groove 11a and the scale marks 11b are both parallel to the long direction of the sliding groove 12 a; the right-angle trapezoidal sliding block 7 is provided with a pointer 3, the pointer 3 is matched with a pull groove 11a in a sliding mode, the pointer 3 is located outside the measuring movable space, and the needle point of the pointer 3 is aligned with the scale mark 11 b; the handheld rod 4 is connected with the isosceles right triangle slider 6, and the isosceles right triangle slider 6 can be pushed to slide and protrude to the outside of the measurement activity space through the handheld rod 4.

Specifically, as shown in fig. 2 and 3, fig. 2 and 3 show two different states of the detection body in the present case, respectively. In fig. 2, the initial state of the test subject is shown for the measurement. When measuring, the isosceles right triangle slider 6 measures the gap outside the active space and inserted into the elevator door leaf 10 by pushing the hand lever 4. Through the mutual sliding fit and wedge effect of isosceles right triangle slider 6 and two right trapezoid sliders 7, impel two right trapezoid sliders 7 to slide simultaneously to the long direction of spout 12a respectively. As shown in fig. 3, the depth value h of the gap of the isosceles right triangle slider 6 inserted into the elevator is equal to the sliding distance of any one of the right trapezoid sliders 7 along the pull groove 11a, so that the acute angle of the right trapezoid slider 7 is set to 45 degrees, which is convenient for calculation and structural design, and the ratio is 1: 1.

Of course, the rubber sleeve 5 may be fitted over the hand-held lever 4 for easy operation. As shown in fig. 1, each right-angle trapezoidal slider 7 is provided with two pointers 3, the scale marks 11b and the pull grooves 11a are provided, one pointer 3 is correspondingly matched with one pull groove 11a in a sliding manner, and one pointer 3 is corresponding to one scale mark 11 b. The gap value of the elevator door leaf 10 is thus determined simultaneously by the two hands 3 for checking purposes.

It should be noted that: because the inclined plane of isosceles right triangle slider 6 does not have the step, the gap value of elevator door leaf 10 demonstrates with being linear proportion's state during the measurement, consequently can realize the measurement of high accuracy to the later stage elevator is maintained and is rectified and improved the debugging.

In a further optimization: the part of the isosceles right triangle slider 6, which is close to the hand-held rod 4, protrudes outwards to form a connecting part 6a, and the hand-held rod 4 is rotatably connected with the connecting part 6 a; and the parts of the two isosceles right trapezoid sliding blocks 7, which are far away from the measurement moving space, are fixedly connected with positioning substrates 2. In the presence of the positioning base plate 2, during measurement, the positioning base plate 2 is aligned with the planes on the two sides of the gap of the elevator door leaf 10, during operation, because the hand-held rod 4 is rotatably connected with the isosceles right triangle slider 6 through the connecting part 6a, an operator can not necessarily need to be over against the planes on the two sides of the gap of the elevator door leaf 10, even if the operator stands on the side, under the guide fiber of the positioning base plate 2, the isosceles right triangle slider 6 can still be inserted into the gap of the elevator door leaf 10 in a self-adjusting mode at an angle vertical to the planes on the two sides of the gap of the elevator door leaf 10 to complete gap measurement, and the operation is simpler and more convenient.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
