Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator maintenance technology, and in particular to a warning sign for elevator maintenance. Background Technology
[0002] An elevator is a vertical transportation device that transports people or goods. It is widely used in high-rise residential buildings and office buildings to facilitate the movement of people and goods between floors. When elevators are in use, regular maintenance and inspection are often carried out to prevent sudden emergency or high-risk malfunctions. During elevator maintenance and repair, warning panels are often placed at the elevator door to warn people not to enter, so as to prevent others from being injured by entering a malfunctioning elevator.
[0003] The warning sign systems commonly used in current elevator maintenance operations have two major technical defects: First, traditional warning signs adopt a fixed, enclosed structure design, and the length of their lateral extension components is usually a preset standard size. However, due to significant differences in the door spacing of different brands of elevators, this easily leads to insufficient matching between the warning sign and the elevator door frame. Second, traditional warning signs are generally placed directly on the ground at the elevator entrance. When someone accidentally bumps into the warning sign, it may move to some extent, thus affecting the warning effect and causing safety hazards due to blurred boundaries of the warning area. Therefore, a new type of warning sign for elevator maintenance is proposed to solve the above problems. Utility Model Content
[0004] (a) Purpose of the utility model
[0005] To address the technical problems existing in the background art, this utility model proposes a warning sign for elevator maintenance. Through a limiting component, suction cup mechanism, first sliding groove, first sliding rod, and limiting hole, the distance between the two second mounting frames can be adjusted according to the door spacing of different elevator brands, improving its applicability. Furthermore, it can be adsorbed and fixed to the inner wall of the elevator door frame, providing a certain degree of fixation for the first mounting frame and preventing significant displacement between the first and second mounting frames in the event of an accidental collision, thus ensuring the warning effect.
[0006] (II) Technical Solution
[0007] This utility model provides a warning sign for elevator maintenance, including a second mounting frame symmetrically distributed on the left and right sides. A first mounting frame is hinged to each of the symmetrically distributed second mounting frames. The inner end face of the second mounting frame is connected to a second warning sign through a plurality of second connecting rods. The inner end face of the first mounting frame is connected to a first warning sign through a plurality of first connecting rods. A plurality of suction cup mechanisms are provided on the side of the first mounting frame away from the second mounting frame.
[0008] The right end of the second mounting frame on the left side is provided with a first sliding slot spaced vertically, and the left end of the second mounting frame on the right side is provided with a first sliding rod distributed vertically. The first sliding rods distributed vertically are slidably connected to the first sliding slots on both sides respectively.
[0009] Limiting holes are equidistantly provided at the upper end of the first sliding rod. A limiting component is installed at the right end of the top of the second mounting frame on the left side. The limiting end of the limiting component passes through the second mounting frame connected to it and extends into the limiting hole that is adapted to it.
[0010] Preferably, the suction cup mechanism includes a connector, a suction cup, a rotating block, a connecting post, a rotating rod, and a suction cup housing. The side of the first mounting frame is connected to the suction cup housing through the connector. The middle part of the connecting post passes through the middle part of the suction cup housing. One end of the connecting post is connected to the suction cup, and the other end of the connecting post is connected to the rotating block. The rotating rod is located on the side of the rotating block.
[0011] Preferably, the limiting assembly includes a handle, a limiting housing, a limiting ring, a spring, and a limiting rod. The limiting housing is located at the top of the second mounting frame on the left side. One end of the limiting rod passes through the upper end of the limiting housing and is connected to the handle. The other end of the limiting rod extends into the limiting hole connected to it. The spring is sleeved on the outside of the limiting rod. The limiting ring is fixed on the outside of the limiting rod. The spring is located between the limiting ring and the inner bottom wall of the limiting housing. The spring and the limiting ring are located inside the limiting housing.
[0012] Preferably, the second warning sign on the left side has a second sliding slot at its right end, and the second warning sign on the right side has a second sliding rod extending into the second sliding slot at its left end.
[0013] Preferably, a limiting block is installed at the end of the second sliding rod away from the second warning sign on the right side, and the limiting block is located inside the second sliding slot.

[0015] Preferably, both the first mounting frame and the second mounting frame are equipped with handles on their tops.
[0016] Preferably, both the second mounting frame and the first mounting frame are equipped with support feet at their bottoms.
[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0018] 1. When in use, this elevator maintenance warning sign can be moved by the operator to the elevator door frame, causing the first mounting frames on both sides to rotate. By adjusting the limiting components, the limiting effect of the limiting components can be canceled, allowing the first sliding rod to slide within the first sliding slot connected to it, thereby adjusting the distance between the second mounting frames on both sides. The distance between the second mounting frames on both sides can be adjusted by inserting the limiting end of the limiting component into different limiting holes, thus allowing adjustment according to the door spacing of different brands of elevators, improving its applicability.
[0019] 2. When adjusting the spacing between the second mounting frames on both sides of this elevator maintenance warning sign according to the door spacing of different brands of elevators, multiple suction cup mechanisms on the first mounting frames on both sides will contact the inner wall of the elevator door frame. Then, by adjusting the multiple suction cup mechanisms, the suction cup mechanisms on both sides can be adsorbed and fixed to the inner wall of the elevator door frame, so as to provide a certain fixing effect for the first mounting frame and prevent the first mounting frame from shifting significantly with the second mounting frame in the event of an accidental collision, thus affecting the warning effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] like Figure 1-5As shown, the present invention proposes an elevator maintenance warning sign, which includes a second mounting frame 6 symmetrically distributed on the left and right sides. A first mounting frame 4 is hinged to each of the symmetrically distributed second mounting frames 6. The inner end face of the second mounting frame 6 is connected to a second warning sign 8 through a plurality of second connecting rods 7. The inner end face of the first mounting frame 4 is connected to a first warning sign 2 through a plurality of first connecting rods 1. A plurality of suction cup mechanisms 3 are provided on the side of the first mounting frame 4 away from the second mounting frame 6.
[0030] The right end of the second mounting frame 6 on the left side is provided with a first sliding slot 14 spaced vertically, and the left end of the second mounting frame 6 on the right side is provided with a first sliding rod 12 distributed vertically. The first sliding rods 12 distributed vertically are slidably connected to the first sliding slots 14 on both sides respectively.
[0031] Limiting holes 13 are equidistantly provided at the upper end of the first sliding rod 12. A limiting component 10 is installed at the right end of the top of the second mounting frame 6 on the left side. The limiting end of the limiting component 10 passes through the second mounting frame 6 connected to it and extends into the limiting hole 13 that matches it.
[0032] In this utility model, the first mounting frame 4 and the second mounting frame 6 are hinged together, so that the first mounting frame 4 can be folded, making it easy for workers to move it.
[0033] When in use, the operator can move it to the elevator door frame, causing the first mounting frames 4 on both sides to rotate. Then, by adjusting the limiting component 10, the limiting function of the limiting component 10 can be canceled, thereby adjusting the first sliding rod 12 to slide within the first sliding slot 14 connected to it, thus adjusting the distance between the second mounting frames 6 on both sides. The distance between the second mounting frames 6 on both sides can be adjusted by inserting the limiting end of the limiting component 10 into different limiting holes 13, thus allowing adjustment according to the door spacing of different brands of elevators, improving the applicability of use.
[0034] When adjusting the spacing between the second mounting frames 6 on both sides according to the different brands of elevator doors, multiple suction cup mechanisms 3 on the first mounting frames 4 on both sides will come into contact with the inner wall of the elevator door frame. Then, by adjusting the multiple suction cup mechanisms 3, the suction cup mechanisms 3 on both sides can be adsorbed and fixed to the inner wall of the elevator door frame, so that they can provide a certain fixing effect for the first mounting frame 4, preventing the first mounting frame 4 and the second mounting frame 6 from shifting significantly in the event of an accidental collision, thus affecting the warning effect.
[0035] In an optional embodiment, the suction cup mechanism 3 includes a connector 301, a suction cup 302, a rotating block 303, a connecting post 304, a rotating rod 305, and a suction cup housing 306. The side of the first mounting frame 4 is connected to the suction cup housing 306 through the connector 301. The middle part of the connecting post 304 passes through the middle part of the suction cup housing 306. One end of the connecting post 304 is connected to the suction cup 302, and the other end of the connecting post 304 is connected to the rotating block 303. The rotating rod 305 is located on the side of the rotating block 303.
[0036] It should be noted that when in use, the first mounting frame 4 and the second mounting frame 6 are first flipped so that they are set at approximately 90° apart, so that the suction cup 302 contacts the inner wall of the elevator door frame (the inner wall of the elevator door frame is usually smooth). Then, the rotating block 303 is rotated by the rotating rod 305, which in turn moves the connecting column 304. The connecting column 304 can then move the suction cup 302 to adhere and fix it to the inner wall of the elevator door frame, so that it can provide a certain fixing effect for the first mounting frame 4 and prevent the first mounting frame 4 and the second mounting frame 6 from shifting significantly in the event of an accidental collision, thus affecting the warning effect.
[0037] The suction cup mechanism 3 has a certain degree of elasticity, so that when it adsorbs the suction cup mechanism 3 to the inner wall of the elevator door frame, the second mounting frame 6 and the first mounting frame 4 do not have to be set at a complete 90° angle.
[0038] In an optional embodiment, the limiting assembly 10 includes a handle 1001, a limiting housing 1002, a limiting ring 1003, a spring 1004, and a limiting rod 1005. The limiting housing 1002 is located at the top of the second mounting frame 6 on the left side. One end of the limiting rod 1005 passes through the upper end of the limiting housing 1002 and is connected to the handle 1001. The other end of the limiting rod 1005 extends into the limiting hole 13 connected to it. The spring 1004 is sleeved on the outside of the limiting rod 1005. The limiting ring 1003 is fixed on the outside of the limiting rod 1005. The spring 1004 is located between the limiting ring 1003 and the inner bottom wall of the limiting housing 1002. The spring 1004 and the limiting ring 1003 are located inside the limiting housing 1002.
[0039] It should be noted that when it is necessary to adjust the distance between the two second mounting frames 6, first pull the handle 1001 upward. At this time, the limiting rod 1005 can drive the limiting ring 1003 to move upward, so that the spring 1004 will retract, thus canceling the limiting effect on the first sliding rod 12. In this way, the position of the first sliding rod 12 in the first sliding slot 14 connected to it can be adjusted. After adjusting to the appropriate position, by releasing the handle 1001, the spring 1004 will extend, so that it can drive the limiting rod 1005 downward through the limiting ring 1003, thus inserting it into the matching limiting hole 13, thereby limiting the first sliding rod 12.
[0040] The spacing between the two second mounting frames 6 can be adjusted by inserting the limit rod 1005 into different limit holes 13, so that it can be adjusted according to the spacing of elevator doors of different brands, thus improving the applicability of use.
[0041] In an optional embodiment, a second sliding slot 16 is provided at the right end of the left second warning sign 8, and a second sliding rod 11 extending into the second sliding slot 16 is installed at the left end of the right second warning sign 8. A limit block 15 is installed at the end of the second sliding rod 11 away from the right second warning sign 8, and the limit block 15 is located inside the second sliding slot 16.
[0042] It should be noted that when the two second warning signs 8 are moving closer or further apart, the second sliding rod 11 will slide within the second sliding slot 16, ensuring the stability of the two second warning signs 8 during movement; and the limiting block 15 can prevent the second sliding rod 11 from disengaging from the second sliding slot 16.
[0043] In an optional embodiment, the first sliding rod 12 is adapted to the interior of the first sliding slot 14.
[0044] It should be noted that this ensures the stability of the first sliding rod 12 moving inside the first sliding slot 14.
[0045] In an optional embodiment, handles 9 are installed on the top of both the first mounting frame 4 and the second mounting frame 6.
[0046] It should be noted that multiple handles 9 facilitate the movement of the second mounting frame 6 and the first mounting frame 4.
[0047] In an optional embodiment, both the bottom of the second mounting frame 6 and the bottom of the first mounting frame 4 are equipped with support feet 5.
[0048] It should be noted that the multiple support feet 5 can provide stable support for the second mounting frame 6 and the first mounting frame 4, thereby stabilizing the second mounting frame 6 and the first mounting frame 4.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
