[0002] With the acceleration of the urbanization process and the popularization of high-rise buildings, elevators, as an important tool for vertical transportation, have received extensive attention for their safety performance. During the operation of elevators, there are gaps between the car and the hoistway wall, between the car and the landing door, and between the landing door and the hoistway wall. If these gaps are too large, it may cause passengers or objects to accidentally fall or be pinched, leading to serious safety accidents. Therefore, regularly inspecting these gaps to ensure they are within a safe range is a key measure to ensure the safe operation of elevators.

[0003] The existing detection methods are usually electronic detections. They use advanced electronic sensors and measuring instruments to quickly and accurately measure the gap widths between the elevator door and the car, and between the car and the hoistway wall in a non-contact manner. The laser rangefinder calculates the distance by emitting a laser beam and receiving the reflected light, while the ultrasonic rangefinder measures the distance by emitting and receiving ultrasonic pulses. The capacitive sensor and the photoelectric sensor respectively determine the distance by measuring the capacitance change and the light blockage.

[0004] However, the existing electronic detection methods increase the dependence on electronic devices. When there are equipment failures, battery depletion, or signal interference, it may lead to the inability to obtain data or incorrect data, and it will also affect the subsequent maintenance and rectification work. For this reason, an inspection mechanism for inspecting elevator gaps is proposed to solve the above problems. Content of the Utility Model

[0022] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 As an embodiment provided by the utility model, an inspection mechanism for inspecting elevator gaps includes a measuring body 1. A knob 2 is rotatably connected to the top of the measuring body 1. A worm 3 is fixedly connected to the bottom of the knob 2. A worm gear 4 is rotatably connected inside the measuring body 1. A transmission column 5 is fixedly connected to one side of the outer wall of the worm gear 4. A first transmission rod 6 is rotatably connected inside the transmission column 5. A second transmission rod 7 is rotatably connected to one side of the outer wall of the transmission column 5. A first sliding groove 9 is formed inside the measuring body 1. A scale line 8 is provided on the top of the measuring body 1. The outer wall of the second transmission rod 7 is slidably connected inside the first sliding groove 9. A connecting block 10 is fixedly connected to the outer wall of the second transmission rod 7. A connecting seat 11 is slidably connected to the outer wall of the measuring body 1. A reset assembly is arranged inside the connecting seat 11, and the reset assembly is used for resetting the limiting assembly;

[0024] Specifically, when using this inspection mechanism for inspecting elevator gaps, first insert the tab on the connecting block 10 into the gap to be detected. This tab is designed very precisely, and its thickness corresponds to one scale in the scale line 8 on the inspection mechanism, which enables it to provide an accurate measurement reference during the detection process. Once the tab is correctly inserted into the gap, the next operation is to rotate the knob 2 on the connecting block 10. The knob 2 is a key component of the inspection mechanism and is mechanically connected and fixed to the worm 3. When the knob 2 is rotated, it drives the worm 3 to rotate. The worm 3 is a shaft with spiral teeth and meshes with the worm gear 4. The worm gear 4 is a gear with corresponding spiral teeth. When the worm 3 rotates, the worm gear 4 will be forced to rotate clockwise. The rotation of the worm gear 4 drives the first transmission rod 6 and the second transmission rod 7 to move through the transmission column 5. The movement of the first transmission rod 6 and the second transmission rod 7 causes the connecting block 10 to move along the first sliding groove 9 to both sides. The first sliding groove 9 is a guiding groove that ensures that the connecting block 10 can move along a predetermined path. As the connecting block 10 moves, the tab will gradually move closer to both sides of the gap until it is in close contact with both sides of the gap. After the tab on the connecting block 10 comes into contact with both sides of the gap, the user of the inspection mechanism can observe the position of the connecting block 10 corresponding to the scale line 8 for reading. Since the thickness of the tab corresponds to one scale in the scale line 8, therefore, by reading the position of the connecting block 10 on the scale line 8, the width of the gap can be accurately known. The design of this inspection mechanism makes the measurement of the gap width simple and accurate, greatly improving the efficiency and reliability of elevator safety inspection.

[0025] Reference Figure 1 - Figure 3 A transmission block 21 is slidably connected to the outer wall of the first sliding column 13. A limiting bead 19 is slidably connected inside the measuring body 1. Both sides of the outer wall of the transmission block 21 are slidably connected inside the connecting seat 11;

[0026] Specifically, in the inspection mechanism for inspecting the elevator gap, when the release knob 12 is released, the first sliding column 13 and the first spring 14 can drive the transmission block 21 to reset the transmission block 21 and the release knob 12 by pulling.

[0027] Refer to Figure 1 - Figure 3 , a transmission block 21 is slidably connected to the outer wall of the first sliding column 13, a limit bead 19 is slidably connected inside the measuring body 1, both sides of the outer wall of the transmission block 21 are slidably connected inside the connecting seat 11, a first wedge block 15 is fixedly connected to the top of the transmission block 21, a hole groove 20 is formed inside the connecting seat 11, the outer wall of the limit bead 19 is slidably connected inside the hole groove 20, a release knob 12 is fixedly connected to one side of the outer wall of the transmission block 21, a second wedge block 16 is slidably connected to the outer wall of the limit bead 19, one side of the outer wall of the release knob 12 is slidably connected to one side of the outer wall of the connecting seat 11, a second sliding column 17 is slidably connected inside the second wedge block 16, one side of the outer wall of the second sliding column 17 is fixedly connected inside the connecting seat 11, a second sliding groove 22 is formed inside the connecting seat 11, one side of the outer wall of the second wedge block 16 is slidably connected inside the second sliding groove 22, a second spring 18 is fixedly connected inside the connecting seat 11, one end of the second spring 18 is fixedly connected to one side of the outer wall of the second wedge block 16, and a bracket 23 is fixedly connected to the bottom of the connecting seat 11;

[0028] Specifically, when it is necessary to remove the measuring body 1, first slide the sliding button 12 upward. The sliding button 12 and the transmission block 21 are fixed through mechanical connection. When the sliding button 12 slides upward, it will drive the transmission block 21 to move upward synchronously. The movement of the transmission block 21 is connected to the first wedge block 15 through mechanical connection. Therefore, when the transmission block 21 moves upward, the first wedge block 15 will also move upward accordingly. The upward movement of the first wedge block 15 causes it to squeeze the second wedge block 16. The second wedge block 16 is a component used in conjunction with the first wedge block 15 and is designed to move in response to the extrusion of the first wedge block 15. After being extruded by the first wedge block 15, the second wedge block 16 will move away from the first wedge block 15. This design enables the second wedge block 16 to generate displacement under the extrusion of the first wedge block 15, thereby realizing the fixation and release of the measuring body 1. After the second wedge block 16 moves a certain distance, the limit bead 19 will no longer be limited by the second wedge block 16. The limit bead 19 is a component in the inspection mechanism used to fix the measuring body 1, and it realizes the limitation of the measuring body 1 through cooperation with the second wedge block 16. When the second wedge block 16 moves to a sufficient distance, the limit bead 19 is no longer restricted by the second wedge block 16, and at this time, the measuring body 1 can be easily removed. The entire process of removing the measuring body 1 is achieved through a series of precise mechanical movements, ensuring the simplicity of the operation and the safe removal of the measuring body 1. This design not only improves the use efficiency of the inspection mechanism but also ensures the safety when removing and installing the measuring body 1. In this way, the measuring body 1 can be conveniently removed, replaced, or maintained, ensuring the normal operation of the inspection mechanism and the accuracy of the measurement.

[0029] Working principle: When using the inspection mechanism for inspecting the elevator gap, first insert the tab on the connecting block 10 into the gap. Then rotate the knob 2, and the knob 2 drives the worm 3 to rotate. Subsequently, the rotation of the worm 3 drives the worm gear 4 to rotate clockwise. When the worm gear 4 rotates, the transmission column 5 will be forced to rotate, and the first transmission rod 6 and the second transmission rod 7 will drive the connecting block 10 to move along the first sliding groove 9 to both sides until the tab on the connecting block 10 contacts both sides of the gap. Subsequently, the reading can be taken according to the position of the connecting block 10 corresponding to the scale line 8. It should be noted that the thickness of the tab is one scale in the scale line 8. When it is necessary to remove the measuring body 1, the sliding button 12 can be slid upward. Subsequently, the sliding button 12 drives the transmission block 21 to move upward, causing the first wedge block 15 to squeeze the second wedge block 16. At this time, the second wedge block 16 will be forced to move away from the first wedge block 15. After the second wedge block 16 moves a certain distance, the limit bead 19 will no longer be limited by the second wedge block 16, and at this time, the measuring body 1 can be removed.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
