Description

Technical Field

[0001] This utility model relates to the field of feeler gauge technology, specifically a feeler gauge for elevator testing. Background Technology

[0002] A feeler gauge, also known as a thickness gauge or gap gauge, is a precision measuring tool used to measure the gap between two mating surfaces. In elevator inspection, feeler gauges are mainly used to measure whether the gaps between various elevator components meet safety standards. It is one of the important tools to ensure the safe operation of elevators. It is commonly used to measure the gaps between the car and guide rails, the gaps between the landing door and the sill, the gaps between the door lock device and the buffer. There are two common types of feeler gauges: single-piece feeler gauges and combination feeler gauges. Single-piece feeler gauges are composed of metal sheets of a single thickness and are often used for fixed gap testing. Combination feeler gauges are made of multiple metal sheets of different thicknesses stacked together, which can measure precise gaps by stacking layers of sheets of different thicknesses.

[0003] The elevator inspection combined feeler gauge uses the "gap filling method". By matching the total thickness of the stacked metal sheets to the gap to be measured, the combined sheet is inserted vertically into the gap and slowly pushed until it contacts the two sides of the surface. It is appropriate to pass through with slight resistance. If the insertion is too loose, the sheet thickness needs to be increased; if it is too tight, the sheet thickness should be reduced.

[0004] In traditional elevator testing, multiple feeler gauges are used in close contact during operation. Over time, the friction between the gauges causes scratches on the surface, resulting in uneven thickness and affecting the accuracy of the test. Utility Model Content

[0005] The purpose of this invention is to provide a feeler gauge for elevator testing, so as to solve the problem mentioned in the background art where feeler gauges rub against each other and cause scratches, affecting the testing accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeler gauge for elevator testing, comprising a U-shaped handle, a slide bar, and a feeler gauge body, and further comprising a relief structure to reduce the friction between the feeler gauge bodies;

[0007] The release structure includes a pressure ring, which is sleeved on the outer wall of the slide rod. Multiple movable rods are installed on one side of the pressure ring. A pull torsion is installed at one end of each movable rod. A fixing spring is sleeved on the outer wall of the slide rod between the U-shaped grip and the pressure ring.

[0008] The U-shaped handle has a sliding rod installed horizontally inside, and multiple feeler gauge bodies are sleeved on the outer wall of the sliding rod on the side away from the fixed spring. The front end of the U-shaped handle has a groove.

[0009] Preferably, the inner diameter of the pressure ring is larger than the outer diameter of the slide rod, and the pressure ring can slide on the outer wall of the slide rod.

[0010] Preferably, the fixing spring is fixedly installed between the pressure ring and the U-shaped grip handle, and the fixing spring is in a compressed state.

[0011] Preferably, one end of each of the movable rods passes through the U-shaped handle, and one end of each of the movable rods extends to one side of the U-shaped handle.

[0012] Preferably, the feeler gauge bodies are all in close contact with each other, and the feeler gauge bodies can slide on the outer wall of the slide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by holding the U-shaped handle and pulling the pull knob, the pull knob drives the movable rod, which in turn drives the pressure ring, causing the pressure ring to slide away from the feeler gauge body on the outer wall of the slide rod. The pressure ring compresses the fixing spring, thus releasing the state of multiple feeler gauge bodies being tightly pressed together. Under the action of the release structure, the distance between the feeler gauge bodies is reduced, thereby reducing the friction between the feeler gauge bodies and preventing wear of the feeler gauge bodies after repeated use, which would lead to inaccurate detection.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-5An elevator inspection feeler gauge includes a U-shaped handle 1, a slide bar 8 and a feeler gauge body 4, and also includes a relief structure to reduce the friction between the feeler gauge bodies 4;

[0022] The release structure includes a pressure ring 6, which is sleeved on the outer wall of the slide rod 8. Multiple movable rods 5 are installed on one side of the pressure ring 6. A pull torque 3 is installed at one end of the movable rod 5. A fixing spring 7 is sleeved on the outer wall of the slide rod 8 between the U-shaped grip handle 1 and the pressure ring 6.

[0023] The U-shaped handle 1 has a slide bar 8 installed horizontally inside, and multiple feeler gauge bodies 4 are sleeved on the outer wall of the slide bar 8 on the side away from the fixed spring 7. The front end of the U-shaped handle 1 has a groove 2.

[0024] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, one end of the movable rod 5 passes through the U-shaped handle 1, and one end of the movable rod 5 extends to one side of the U-shaped handle 1. The inner diameter of the pressure ring 6 is larger than the outer diameter of the slide rod 8, and the pressure ring 6 can slide on the outer wall of the slide rod 8. In use, the movable rod 5 is driven by the pull and twist 3, so that the movable rod 5 drives the pressure ring 6, and the pressure ring 6 slides on the outer wall of the slide rod 8 in a direction away from the feeler gauge body 4.

[0025] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the fixing spring 7 is fixedly installed between the pressure ring 6 and the U-shaped grip handle 1, and the fixing spring 7 is in a compressed state. When in use, the fixing spring 7 is compressed by the pressure ring 6, so that the state of multiple feeler gauge bodies 4 sticking together can be released.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the feeler gauge bodies 4 are all in close contact with each other, and the feeler gauge bodies 4 can slide on the outer wall of the slide bar 8. When in use, the pressure ring 6 moves away from the feeler gauge bodies 4, the friction between the feeler gauge bodies 4 is reduced, and the feeler gauge bodies 4 are pushed out from the inside of the U-shaped grip handle 1 through the groove 2, so that the feeler gauge bodies 4 rotate with the slide bar 8 as the fulcrum.

[0027] Working principle: The operator holds the U-shaped handle 1 and pulls the pull knob 3. The pull knob 3 drives the movable rod 5, which in turn drives the pressure ring 6. The pressure ring 6 slides away from the feeler gauge body 4 on the outer wall of the slide rod 8. The pressure ring 6 compresses the fixing spring 7, which releases the tight contact between the multiple feeler gauge bodies 4. The friction between the feeler gauge bodies 4 is reduced. The operator pushes the feeler gauge body 4 out of the U-shaped handle 1 through the groove 2, allowing the feeler gauge body 4 to rotate around the slide rod 8. Then, the pull knob 3 is released. Under the reaction force of the fixing spring 7, the pressure ring 6 slides closer to the feeler gauge body 4 on the outer wall of the slide rod 8, and the feeler gauge body 4 is tightened again. This prevents the gap between the feeler gauge bodies 4 from being too large, which would lead to inaccurate detection. The elevator gap can then be detected by pushing out the feeler gauge body 4.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
