Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance technology, and in particular to an elevator inspection ruler with an adjustment mechanism. Background Technology

[0002] In modern buildings, the widespread use of elevators makes their safe operation crucial. Elevator inspection is a key link in ensuring the safe and reliable operation of elevators, and elevator inspection rulers, as a commonly used inspection tool, play an indispensable role in the installation, maintenance, and periodic inspection of elevators.

[0003] Traditional elevator inspection rulers are usually simple in structure and have relatively limited functions. When measuring elevator gaps, the measuring rulers used can only measure gaps and cannot measure other lengths. This requires multiple measuring tools during elevator inspection, increasing the burden on the staff. Therefore, an elevator inspection ruler with an adjustment mechanism has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an elevator inspection ruler with an adjustment mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An elevator inspection ruler with an adjustment mechanism includes a housing. A baffle is fixedly connected to one side of one end of the outer wall of the housing. A strip-shaped hole is opened on the side of the housing near the baffle. Two guide rods are fixedly connected between the two ends inside the housing. The same L-shaped plate is slidably fitted on the circumferential surface of the two guide rods. A circular hole adapted to the guide rod is opened on the L-shaped plate. A spring is fitted on the end of each guide rod near the baffle. A first push block is fixedly connected to the top of the L-shaped plate. A triangular groove is opened on the end of the L-shaped plate away from the strip-shaped hole, and an anti-slip piece is fixedly connected to the triangular groove. An adjustment mechanism is provided on the side of the L-shaped plate near the strip-shaped hole. The adjustment mechanism includes two strip frames fixedly connected to the two ends of the side of the L-shaped plate near the strip-shaped hole. A vertical hole is opened on the side of each strip frame away from the L-shaped plate. A second stop block is slidably connected inside each of the two strip frames. An oblique hole is opened on each of the two second stop blocks, and the two oblique holes are in opposite directions. The setting of the two opposite oblique holes makes the two second stop blocks always move in opposite directions.

[0007] As a further embodiment of this utility model, the adjusting mechanism further includes two fixing blocks fixedly connected to the side of the L-shaped plate near the strip hole. T-shaped grooves are provided on the side of each fixing block away from the L-shaped plate. T-shaped blocks are slidably connected to the sides of each T-shaped block. Magnetic blocks are fixedly connected to the outer sides of each T-shaped block. A common stop rod is fixedly sleeved between the two magnetic blocks, and both ends of the stop rod are slidably connected to adjacent vertical and oblique holes. Iron blocks are fixedly connected to the top and bottom of the side of each fixing block away from the L-shaped plate, and the iron blocks are compatible with the magnetic blocks. The iron blocks facilitate the fixing of the stop rod.

[0008] As a further embodiment of this utility model, the outer shell is provided with a first scale and a second scale on the side near the strip hole.

[0009] As a further embodiment of this utility model, a limiting mechanism is provided on the inner side of the outer shell away from the strip hole. The limiting mechanism includes a fixed rod fixedly connected to one side of the inner wall of the outer shell. The same sliding plate is slidably sleeved on the circumferential surface of the two fixed rods. Both ends of the sliding plate are provided with round holes adapted to the fixed rods. The other ends of the two fixed rods are fixedly connected with protrusions. The ends of the two fixed rods near the side wall of the outer shell are sleeved with second springs. The end of the sliding plate near the L-shaped plate is fixedly connected with two connecting plates. The other ends of the two connecting plates are fixedly connected with the same strip plate, and the other end of the strip plate is fixedly connected with a triangular block. The side of the sliding plate near the L-shaped plate is also fixedly connected with a trapezoidal inclined block. Through the setting of the limiting mechanism, the L-shaped plate is controlled.

[0010] As a further embodiment of this utility model, the triangular block is adapted to the triangular groove, and anti-slip plates are provided at the top and bottom of the triangular block. Through the cooperation of the triangular block and the triangular groove, the L-shaped plate can be locked and will not be pushed by the spring.

[0011] As a further embodiment of this utility model, a top cover is fixedly connected to the top of the outer shell, and a rectangular hole adapted to the first push block is opened in the middle of the top cover. A straight hole is opened near the trapezoidal inclined block of the top cover, and the same square rod is fixedly connected between the two ends of the straight hole. A second push block is slidably sleeved on the square rod. A square hole adapted to the square rod is opened on the second push block. A push rod is fixedly connected to the bottom of the square rod, and the push rod is adapted to the trapezoidal inclined block.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model, by employing technical means such as adjustment mechanisms and limiting mechanisms, and through the cooperation of baffles and different second blocks, enables the measuring ruler to measure the width of smaller gaps as well as the width of other longer equipment. This effectively solves the problem of the single measurement function of the measuring ruler mentioned in the background art, and further realizes the adjustment of the measurement range by switching the adjustment mechanism, thereby expanding the functionality and practicality of the measuring ruler and enabling it to meet the measurement needs of different positions in elevator inspection.

Two guide rods 3 are fixedly connected between the two ends inside the housing 1. The same L-shaped plate 4 is slidably fitted on the circumferential surface of the two guide rods 3. A circular hole adapted to the guide rods 3 is opened on the L-shaped plate 4. A spring 301 is fitted on the end of each guide rod 3 near the baffle 101. A first push block 401 is fixedly connected to the top of the L-shaped plate 4. A triangular groove 402 is opened on the end of the L-shaped plate 4 away from the strip-shaped hole 104. An anti-slip plate is fixedly connected to 402. An adjustment mechanism 5 is provided on the side of the L-shaped plate 4 near the strip hole 104. The adjustment mechanism 5 includes two strip frames 501 fixedly connected to both ends of the side of the L-shaped plate 4 near the strip hole 104. Each of the two strip frames 501 has a vertical hole 502 on the side away from the L-shaped plate 4. A second stop block 503 is slidably connected inside each of the two strip frames 501. Each of the two second stop blocks 503 has an oblique hole 504, and the two oblique holes 504 are in opposite directions. The oblique holes 504 are designed so that when the stop bar 506 is at the top or bottom, only one second stop block 503 is always extended.

[0024] In this embodiment, the adjustment mechanism 5 further includes two fixing blocks 505 fixedly connected to the side of the L-shaped plate 4 near the strip hole 104. T-shaped grooves 507 are provided on the side of the two fixing blocks 505 away from the L-shaped plate 4. T-shaped blocks are slidably connected in the two T-shaped grooves 507. Magnetic blocks 509 are fixedly connected to the outside of the two T-shaped blocks. The same stop rod 506 is fixedly sleeved between the two magnetic blocks 509. Both ends of the stop rod 506 are slidably connected in the adjacent vertical hole 502 and oblique hole 504. Iron blocks 508 are fixedly connected to the top and bottom of the side of the two fixing blocks 505 away from the L-shaped plate 4. The iron blocks 508 are compatible with the magnetic blocks 509.

[0025] In this embodiment, the outer shell 1 is provided with a first scale 102 and a second scale 103 on the side near the strip hole 104. Through the cooperation of the first scale 102 and the second scale 103, different second stops 503 can measure different ranges of distance.

[0026] In this embodiment, a limiting mechanism 6 is provided on the inner side of the outer shell 1 away from the strip hole 104. The limiting mechanism 6 includes a fixing rod 601 fixedly connected to one side of the inner wall of the outer shell 1. The same sliding plate 603 is slidably sleeved on the circumferential surface of the two fixing rods 601. Both ends of the sliding plate 603 are provided with round holes that are adapted to the fixing rods 601. The other ends of the two fixing rods 601 are fixedly connected with protrusions. The ends of the two fixing rods 601 near the side wall of the outer shell 1 are each sleeved with a second spring 602. The end of the sliding plate 603 near the L-shaped plate 4 is fixedly connected with two connecting plates 604. The other ends of the two connecting plates 604 are fixedly connected with the same strip plate 605. The other end of the strip plate 605 is fixedly connected with a triangular block 606. The side of the sliding plate 603 near the L-shaped plate 4 is also fixedly connected with a trapezoidal inclined block 607.

[0027] In this embodiment, the triangular block 606 is adapted to the triangular groove 402, and anti-slip plates are provided on the top and bottom of the triangular block 606. The triangular block 606 is in close contact with the triangular groove 402, thereby fixing the L-shaped plate 4 and preventing it from being pushed by the spring 301.

[0028] In this embodiment, a top cover 2 is fixedly connected to the top of the outer shell 1, and a rectangular hole adapted to the first push block 401 is opened in the middle of the top cover 2. A straight hole is opened near the trapezoidal inclined block 607 of the top cover 2, and the same square rod 7 is fixedly connected between the two ends of the straight hole. A second push block 701 is slidably sleeved on the square rod 7. A square hole adapted to the square rod 7 is opened on the second push block 701. A push rod 702 is fixedly connected to the bottom of the square rod 7, and the push rod 702 is adapted to the trapezoidal inclined block 607. By pushing the second push block 701, the limiting mechanism 6 is controlled, and the L-shaped plate 4 is controlled.

[0029] Working principle: By pushing the stop bar 506 up and down, the magnetic block 509 attracts the iron block 508 at the bottom or top respectively. Under the action of the two opposite oblique holes 504, the two second stops 503 extend and retract into the strip frame 501 as the stop bar 506 is in different positions. When one second stop 503 extends, the other second stop 503 will retract. When needed, the first push block 401 pushes the L-shaped plate 4 close to one end of the baffle 101 until the L-shaped plate 4 abuts against the inner wall of the outer shell 1. The spring 301 is compressed. The anti-slip plate of the triangular groove 402 and the triangular block 606 prevents the L-shaped plate 4 from returning to its original position. When measuring gaps such as elevator doors, the second stop 503 near the baffle 101 is extended, so that the second stop... Insert 503 and the baffle 101 into the gap. By pushing the second push block 701, the push rod 702 pushes the trapezoidal inclined block 607, causing the second spring 602 to be compressed. The triangular block 606 moves away from the triangular groove 402, causing the spring 301 to rebound until the baffle 101 and the second baffle 503 contact the two ends of the gap. At this time, the second push block 701 is reset, so that the triangular block 606 continues to press the triangular groove 402, thus fixing the first push block 401. Then, remove the device. By observing the second baffle 503 and the first scale 102, the size of the gap can be checked. When it is necessary to measure other larger distances of the elevator, by moving the baffle rod 506, the second baffle 503, which is away from the baffle 101, extends out. By performing the same operation as above, the second scale 103 can be observed to check the size.
