An easy-to-operate elevator inspection auxiliary device

Abstract

This utility model relates to the field of elevator inspection technology and provides an easy-to-operate elevator inspection auxiliary device, including: a strip plate, and two hollow tubes symmetrically fixedly connected to opposite sides of the strip plate. In this utility model, by manually rotating screw two, the limiting state of the ring is released, allowing the ring to move to one side along the outer surface of the hollow tube, simultaneously moving the slider and pressure sensor to one side. Then, by rotating screw two in the opposite direction, it is pressed against the outer surface of the hollow tube, limiting the ring. When a child manually rotates screw one, releasing the limiting state of the movable rod and pushing the movable rod towards the inside of the hollow tube, the movable rod will collide with the pressure sensor, triggering an alarm via the controller. This not only warns the child but also promptly notifies maintenance personnel, preventing the child from moving the device at will and ensuring the safety of subsequent passengers.

Description

Technical Field

[0001] This utility model relates to the field of elevator inspection technology, and in particular to an easy-to-operate elevator inspection auxiliary device. Background Technology

[0002] An elevator is a transportation device that serves the floors of a building. With the continuous construction of high-rise buildings in cities, elevators have gradually become a necessity of life. After a period of use, elevators need to be inspected regularly by staff to ensure their normal operation.

[0003] In the current technology, during the elevator inspection process, protective barriers need to be placed at the elevator entrance to warn people not to approach. However, the existing protective barriers are relatively simple and are usually just placed at the elevator entrance. When playful children encounter them, they may move the protective barriers at will, making it impossible for subsequent elevator riders to accurately determine whether the elevator inspection has been completed. This makes it difficult for people to ride the elevator with peace of mind, which may lead to dissatisfaction among people with the professionalism of the property management's elevator inspection. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the existing technology that, during the elevator inspection process, it is necessary to place a protective fence at the elevator entrance to warn people not to approach. However, the existing protective fences are relatively simple and are usually just placed at the elevator entrance. When there are playful children, they may move the protective fence at will, making it impossible for subsequent elevator riders to accurately judge whether the elevator inspection has been completed. This makes people feel uneasy when riding the elevator, which may lead to dissatisfaction among people with the professionalism of the property elevator inspection.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an easy-to-operate elevator inspection auxiliary device, comprising: a strip plate, and further comprising:

[0006] Two hollow tubes are symmetrically fixedly connected to opposite sides of the strip plate. Two movable rods are symmetrically slidably connected inside the hollow tubes. A suction cup is fixedly connected to one end of each movable rod. Two screws are symmetrically threaded onto the outer surface of the hollow tubes. An L-shaped strip is fixedly connected to the outer surface of each movable rod near the suction cup. Elastic shielding cloths are fixedly connected to opposite sides of multiple L-shaped strips. Two circular rings are symmetrically slidably connected to the outer surface of the hollow tubes. Two sliders are symmetrically slidably connected inside one of the hollow tubes. A pressure sensor is fixedly connected to one side of each slider. The slider is fixedly connected to the circular ring. A screw is threaded onto the outer surface of the circular ring. An alarm is fixedly connected to the outer surface of the hollow tube.

[0007] Preferably, two strip grooves are symmetrically formed on the outer surface of the movable rod, and one end of the screw is movably connected to the inside of the strip groove.

[0008] Preferably, two strip grooves are symmetrically formed on the outer surface of one of the hollow tubes, and the outer surface of the slider is slidably connected to the inside of the strip grooves.

[0009] Preferably, a hollow strip is fixedly connected to one side of the strip plate, a movable strip is slidably connected inside the hollow strip, and an arc plate is fixedly connected to one side of the movable strip.

[0010] Preferably, the top of the movable strip is provided with a plurality of limiting holes at equal intervals, and the top of the hollow strip is slidably connected to a limiting rod, one end of which is slidably connected inside one of the limiting holes.

[0011] Preferably, a spring is provided on the outer surface of the limiting rod, and the spring is fixedly connected to the limiting rod and the hollow strip respectively.

[0012] Preferably, the outer surface of the elastic shielding cloth is fixedly connected with multiple reflective strips at equal intervals.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention allows the child to manually rotate screw two, moving it outwards to release the limiting state of the ring. This allows the ring to move to one side along the outer surface of the hollow tube, simultaneously moving the slider and pressure sensor to one side, bringing the pressure sensor closer to the movable rod. Then, by rotating screw two in the opposite direction, it presses against the outer surface of the hollow tube, limiting the ring. When a child manually rotates screw one, releasing the limiting state of the movable rod and pushing it towards the inside of the hollow tube, the movable rod will collide with the pressure sensor, causing it to generate a signal that is transmitted to the controller. The controller then activates the alarm, thus warning the child and promptly notifying maintenance personnel, preventing the child from moving the device and ensuring the safety of subsequent elevator users.

[0015] This invention allows the movable rod to be released from its clamping state by manually rotating the screw one to move it outward. The movable rod can then move outward along the inside of the hollow tube, attaching the suction cup to the inner wall of the elevator shaft. The device is then attached to the elevator shaft location by the suction cup, with the L-shaped strip contacting the outer wall of the elevator shaft. Next, the screw one is rotated in the opposite direction by hand, inserting it into the strip groove one and clamping the movable rod, thus keeping the hollow tube and movable rod relatively fixed. Simultaneously, the elastic blinding cloth can be stretched to an appropriate degree and unfolded for covering. This allows for adjustment according to different elevator shaft widths, improving the applicability of the device and making it simple and convenient to operate.

[0016] This invention allows the limiting rod to be pulled upwards by hand, moving it out of the limiting hole and releasing the restriction on the movable strip. Simultaneously, the spring is stretched, allowing the arc-shaped plate to be pushed to one side, causing the movable strip to slide outwards along the inside of the hollow strip. This pushes the elastic covering cloth outwards, making it appear in an arc shape. Then, the limiting rod is released, allowing it to be inserted into another limiting hole under the restoring force of the spring, thus limiting the movable strip. This facilitates timely observation by personnel and, in conjunction with the reflective strip, enhances the warning effect of the device. Attached Figure Description

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figure 1-5 As shown, this utility model provides an easy-to-operate elevator inspection auxiliary device, including: a strip plate 1, and two hollow tubes 2, symmetrically fixedly connected to opposite sides of the strip plate 1. Two movable rods 201 are symmetrically slidably connected inside the hollow tubes 2. A suction cup 202 is fixedly connected to one end of each movable rod 201. Two screws 203 are symmetrically threaded onto the outer surface of the hollow tubes 2. An L-shaped strip 204 is fixedly connected to the outer surface of the movable rods 201 near the suction cup 202. An elastic shielding cloth 205 is fixedly connected to the opposite side of the multiple L-shaped strips 204. Two rings 3 are symmetrically slidably connected to the outer surface of the hollow tubes 2. Two sliders 302 are symmetrically slidably connected inside one of the hollow tubes 2. A pressure sensor 303 is fixedly connected to one side of each slider 302. The slider 302 is fixedly connected to the ring 3. A screw 304 is threadedly connected to the outer surface of the ring 3. An alarm 301 is fixedly connected to the outer surface of the hollow tubes 2.

[0027] Furthermore, such as Figure 1-5 As shown, two strip grooves 207 are symmetrically formed on the outer surface of the movable rod 201. One end of the screw 203 is movably connected to the inside of the strip groove 207. Through the setting of the strip groove 207, the screw 203 can slide along the inside of the strip groove 207 to limit and guide the movable rod 201.

[0028] Furthermore, such as Figure 1-5 As shown, two strip grooves 208 are symmetrically opened on the outer surface of one of the hollow tubes 2. The outer surface of the slider 302 is slidably connected to the inside of the strip groove 208. With the above arrangement, the slider 302 can slide to one side along the inside of the strip groove 208.

[0029] Furthermore, such as Figure 1-5 As shown, a hollow strip 4 is fixedly connected to one side of the strip plate 1, and a movable strip 401 is slidably connected inside the hollow strip 4. An arc plate 402 is fixedly connected to one side of the movable strip 401. By moving the movable strip 401 outward along the inside of the hollow strip 4, the arc plate 402 can push the elastic cover cloth 205 to expand the display range of the elastic cover cloth 205.

[0030] Furthermore, such as Figure 1-5As shown, multiple limiting holes 405 are equidistantly provided on the top of the movable strip 401. A limiting rod 403 is slidably connected to the top of the hollow strip 4. One end of the limiting rod 403 is slidably connected to the inside of one of the limiting holes 405. By pulling the limiting rod 403 upward by hand, it is disengaged from the inside of the limiting hole 405, thus releasing the limitation on the movable strip 401.

[0031] Furthermore, such as Figure 1-5 As shown, a spring 404 is provided on the outer surface of the limiting rod 403. The spring 404 is fixedly connected to the limiting rod 403 and the hollow bar 4 respectively. Under the reset force of the spring 404, the limiting rod 403 can be inserted into the limiting hole 405 to limit the movable bar 401.

[0032] Furthermore, such as Figure 1-5 As shown, multiple reflective strips 206 are fixedly connected at equal intervals on the outer surface of the elastic shielding cloth 205.

[0033] Working Principle: When maintenance personnel need to inspect the elevator, they manually rotate screw 203 to move it outwards, releasing the clamping state on movable rod 201. This allows movable rod 201 to move outwards along the interior of hollow tube 2, causing suction cup 202 to adhere to the inner wall of the elevator entrance passage. The suction cup 202 then attaches the device to the elevator entrance position, with L-shaped strip 204 contacting the outer wall of the elevator entrance. When the device is subjected to external force, it is supported by L-shaped strip 204. Then, by manually rotating screw 203 in the opposite direction, it is inserted into strip groove 207, and the movable rod 201... 1. Tighten the connection to keep the hollow tube 2 and the movable rod 201 relatively fixed. Simultaneously, the elastic blocking cloth 205 can be stretched to an appropriate degree, allowing it to be unfolded for covering. This allows for adjustment according to different elevator opening widths, improving the applicability of the device. Operation is relatively simple and convenient. Then, manually rotate the screw 304 to move it outwards, releasing the limiting state on the ring 3. At this point, the ring 3 can move to one side along the outer surface of the hollow tube 2, simultaneously driving the slider 302 and pressure sensor 303 to move to one side, bringing the pressure sensor 303 closer to the movable rod 201. Then... By rotating screw 204 in the reverse direction, it is pressed against the outer surface of hollow tube 2, limiting the ring 3. When a child rotates screw 203 to release the limitation on movable rod 201 and pushes it towards the inside of hollow tube 2, the movable rod 201 will collide with pressure sensor 303, causing it to generate a signal that is transmitted to the controller. The controller then activates alarm 301, which not only warns the child but also promptly notifies maintenance personnel, preventing the child from moving the device at will and ensuring the safety of subsequent passengers. The limit rod 403 can be manually moved... Pull it upwards to move it out of the limiting hole 405, releasing the limitation on the movable strip 401. Simultaneously, the spring 404 is stretched. At this time, the arc plate 402 can be pushed to one side, causing the movable strip 401 to slide outwards along the inside of the hollow strip 4. The arc plate 402 pushes the elastic shielding cloth 205 outwards, making the elastic shielding cloth 205 appear in an arc shape. Then, release the limiting rod 403, allowing it to be inserted into the other limiting hole 405 under the restoring force of the spring 404, limiting the movable strip 401. This makes it easy for personnel to observe in time, and with the cooperation of the reflective strip 206, improves the warning effect of this device.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
