Description

Technical Field

[0001] This utility model relates to the field of elevator button technology, specifically to an elevator button housing that is easy to maintain. Background Technology

[0002] As the core carrier for user interaction with the elevator, the elevator button housing is a type of elevator equipment suitable for various densely populated scenarios such as residences, shopping malls, hospitals, and subway stations.

[0003] Existing elevator button housings are typically made using integrated injection molding or screw fastening. The main body of the housing, the control panel, and internal connectors form a fixed whole. When a button malfunctions and requires maintenance, it is necessary to first remove the elevator car wall panel or the external decorative parts of the housing, and then use special tools to remove multiple fixing screws before the entire housing can be removed from its mounting position. The need for complete disassembly for malfunctions makes maintenance procedures cumbersome, time-consuming, and labor-intensive. Furthermore, repeated disassembly and reassembly can easily cause stripped screws and wear on the edges of the housing, further increasing the difficulty of subsequent maintenance. Therefore, we have introduced an elevator button housing that is easier to maintain. Utility Model Content

[0007] As a preferred technical solution of this utility model: the connecting component includes a first spring and a first convex pin provided in the inner cavity of the circular groove, a second slot is provided on the inner wall of the first convex pin, a second convex pin and a second spring are provided in the inner cavity of the guide groove, and a connecting rod is fixedly assembled on the outer wall of the second convex pin.

[0008] As a preferred technical solution of this utility model: the first spring is located at the bottom of the first convex pin, with one end overlapping the bottom of the first convex pin and the other end overlapping the inner wall of the circular groove. The top of the first convex pin is spherical, and the outer wall of the sphere is adapted to the shape of the inner wall of the first slot. The bottom side wall of the first convex pin is slidably fitted to the inner wall of the circular groove. One end of the outer wall of the second convex pin is inclined, and the bottom of the inclined surface is slidably fitted to the top of the first convex pin. The other end of the second convex pin is slidably fitted to the inner wall of the guide groove. The second spring is located on the outer wall of the connecting rod, with one end overlapping the outer wall of the second convex pin and the other end overlapping the inner wall of the guide groove. The outer wall of the second slot is adapted to the shape of the inner wall of the second slot.

[0009] As a preferred technical solution of this utility model: the panel cleaning assembly includes a corrugated telescopic tube disposed on the outer wall of a support frame, a throttle valve disposed at the top of the corrugated telescopic tube, an air pipe disposed at the bottom of the corrugated telescopic tube, a one-way valve disposed on the outer wall of the air pipe, a sealing box fixedly installed on the outer wall of the support frame away from the corrugated telescopic tube, an air nozzle disposed on the side wall of the sealing box, a third spring disposed in the inner cavity of the corrugated telescopic tube, a sliding groove opened on the outer wall of the support frame, an L-shaped rod disposed on the outer wall of the support frame, an mounting plate fixedly mounted on the outer wall of the L-shaped rod, and a cleaning cylinder disposed on the outer wall of the mounting plate.

[0010] As a preferred technical solution of this utility model: the corrugated telescopic tube, throttle valve, air pipe, one-way valve, sealing box, air nozzle, third spring, slide groove, L-shaped rod and mounting plate are regarded as a set of movable components, and the number of such movable components is two sets respectively arranged on both sides of the outer wall of the support frame. The throttle valve is connected to the air inlet of the corrugated telescopic tube. One end of the air pipe is connected to the air outlet of the corrugated telescopic tube, and the other end is connected to the air inlet of the sealing box. The inner cavity of the corrugated telescopic tube is provided with a piston plate, and the third spring is located at the bottom of the piston plate. One end of the third spring overlaps with the inner wall of the corrugated telescopic tube, and the other end overlaps with the piston plate. One end of the L-shaped rod is fixedly connected to the top of the corrugated telescopic tube, and the other end is slidably fitted against the inner wall of the slide groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This easy-to-maintain elevator button housing utilizes a first spring to drive a first convex pin to slide along a circular groove. When the operating panel is in contact with the main housing, the first convex pin automatically springs back and inserts into the first slot, completing the initial locking. During this process, the spherical surface at the top of the first convex pin presses against the inclined surface of the second convex pin, compressing the second spring to store energy. This causes the second convex pin to automatically spring back and insert into the second slot after the first convex pin is fully locked. This enhances the connection stability between the positioning pin and the positioning groove, thereby preventing the locking from loosening due to elevator vibration. This ensures the long-term reliability of the housing and further improves the convenience and efficiency of maintenance and disassembly.

[0012] 2. This easy-to-maintain elevator button housing, driven by a pull-down mounting plate, slides an L-shaped rod along a groove, causing the corrugated telescopic tube to compress and the cleaning cylinder to move synchronously. During this process, the piston plate inside the corrugated telescopic tube compresses the third spring, causing the gas inside the tube to be transported to the sealed box through the air pipe. The gas is then directed towards the end face of the control panel through the air nozzle, achieving the blowing away of floating dust and impurities in crevices. At the same time, the cleaning cylinder slides with the mounting plate and fits against the end face of the control panel, thus achieving dual cleaning of blowing and wiping, avoiding cleaning dead corners, ensuring thorough cleaning of the control panel, further improving the convenience of daily cleaning and maintenance, and reducing cleaning-related maintenance time.

[0015] 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.

[0016] Please see Figure 1 - Figure 6 An easy-to-maintain elevator button housing includes a main housing 1, a positioning pin 2 fixedly installed on the side wall of the main housing 1, an operation panel 3 provided on the outer wall of the main housing 1, a positioning groove 4 opened on the side wall of the operation panel 3, a support frame 5 fixedly installed on the outer wall of the operation panel 3, a circular groove 6 opened on the inner wall of the positioning pin 2, a first slot 7 and a guide groove 8 respectively opened on the inner wall of the positioning groove 4, a connecting component 9 provided in the inner cavity of the positioning pin 2, and a panel cleaning component 10 provided on the outer wall of the support frame 5. In the above structure, the main housing 1 is used as the base, and the positioning pin 2 on its side wall and the positioning groove 4 of the operation panel 3 form an assembly reference. The support frame 5 on the outer wall of the operation panel 3 provides installation support for the panel cleaning component 10. The circular groove 6 on the inner wall of the positioning pin 2 and the first slot 7 and guide groove 8 of the positioning groove 4 together build a locking and unlocking motion path for the connecting component 9, thereby greatly shortening the maintenance time.

[0017] In a preferred embodiment: the circular groove 6, the first slot 7, the guide groove 8 and the connecting component 9 are regarded as a group of movable components, and there are four groups of such movable components, which are arranged in a rectangular array. The outer wall of the positioning pin 2 is adapted to the shape of the inner wall of the positioning groove 4. In the above structure, by setting the circular groove 6, the first slot 7, the guide groove 8 and the connecting component 9 as four sets of rectangular array movable components, the force is uniform when the positioning pin 2 is inserted into the positioning groove 4, thereby avoiding component deformation or assembly loosening caused by local stress, reducing disassembly jamming during maintenance. At the same time, the shape of the positioning pin 2 and the positioning groove 4 are adapted to achieve automatic alignment of the two during assembly, eliminating the need for repeated calibration and further simplifying maintenance disassembly and assembly operations.

[0018] In a preferred embodiment: the connecting assembly 9 includes a first spring 901 and a first convex pin 902 provided in the inner cavity of the circular groove 6, a second slot 903 is provided on the inner wall of the first convex pin 902, a second convex pin 904 and a second spring 905 are provided in the inner cavity of the guide groove 8, and a connecting rod 906 is fixedly assembled on the outer wall of the second convex pin 904. In a preferred embodiment: the first spring 901 is located at the bottom of the first convex pin 902, with one end overlapping the bottom of the first convex pin 902 and the other end overlapping the inner wall of the circular groove 6. The top of the first convex pin 902 is spherical, and the outer wall of the sphere is adapted to the shape of the inner wall of the first slot 7. The bottom side wall of the first convex pin 902 is slidably fitted to the inner wall of the circular groove 6. One end of the outer wall of the second convex pin 904 is inclined, and the bottom of the inclined surface is slidably fitted to the top of the first convex pin 902. The other end of the second convex pin 904 is slidably fitted to the inner wall of the guide groove 8. The second spring 905 is located on the outer wall of the connecting rod 906, with one end overlapping the outer wall of the second convex pin 904 and the other end overlapping the inner wall of the guide groove 8. The outer wall of the second slot 903 is adapted to the shape of the inner wall of the second slot 903. In the above structure, when the positioning pin 2 is inserted into the outer wall of the positioning groove 4, the first convex pin 902 first contacts the inner wall of the positioning groove 4. This causes the bottom of the first convex pin 902 to slide along the inner wall of the circular groove 6 under pressure, simultaneously driving the first spring 901 to compress. This causes the first convex pin 902 to retract into the inner cavity of the circular groove 6. At this point, after the operation panel 3 is completely attached to the outer wall of the main housing 1, the positioning groove 4 is completely attached to the outer wall of the positioning pin 2. The first convex pin 902 then aligns with the inner wall of the first slot 7, allowing it to spring back and re-insert into the first slot 7 using the compressed first spring 901. In the inner cavity of slot 7, during this process, the spherical surface of the top of the first convex pin 902 contacts the bottom of the inclined end of the second convex pin 904. This causes the second convex pin 904, under the pressure of the first convex pin 902, to slide along the inner wall of the guide slot 8 through the inclined surface, simultaneously compressing the second spring 905. When the top of the first convex pin 902 is fully inserted into the inner cavity of the first slot 7, the inclined end of the second convex pin 904 aligns with the inner wall of the second slot 903. At this point, the second convex pin 904 rebounds and inserts into the inner cavity of the second slot 903 using the compression of the second spring 905. The first convex pin 902 is secured to prevent it from loosening due to vibration. When disassembly is required, pulling the connecting rod 906 causes the second convex pin 904 to slide along the inner wall of the guide groove 8. This sliding pin compresses the second spring 905, causing it to disengage from the inner cavity of the second slot 903. This releases the lock on the first convex pin 902. Then, by pulling the operating panel 3, the spherical top of the first convex pin 902 is guided by the external force, allowing its spherical surface to align with the arc surface of the first slot 7. This causes the first convex pin 902 to exit the inner cavity of the first slot 7. At this time, the first convex pin 902 will be squeezed by the inner wall of its positioning groove 4, causing the bottom of the first convex pin 902 to slide along the inner wall of the circular groove 6 again. At this time, the first spring 901 will also enter the compressed state again, so that after the positioning groove 4 is completely separated from the outer wall of the positioning pin 2, it will release the second slot 903, and the second convex pin 904 will be reset by the rebound of the second spring 905. At the same time, after the first convex pin 902 is no longer squeezed by the inner wall of the positioning groove 4, it will be reset by the rebound of the first spring 901, and return to the initial state in sequence, thereby improving the efficiency of its maintenance.

[0019] In a preferred embodiment: the panel cleaning assembly 10 includes a corrugated telescopic tube 101 disposed on the outer wall of a support frame 5, a throttle valve 102 disposed at the top of the corrugated telescopic tube 101, an air pipe 103 disposed at the bottom of the corrugated telescopic tube 101, a one-way valve 104 disposed on the outer wall of the air pipe 103, a sealing box 105 fixedly installed on the outer wall of the support frame 5 away from the corrugated telescopic tube 101, an air nozzle 106 disposed on the side wall of the sealing box 105, a third spring 107 disposed in the inner cavity of the corrugated telescopic tube 101, a sliding groove 108 opened on the outer wall of the support frame 5, an L-shaped rod 109 disposed on the outer wall of the support frame 5, an mounting plate 110 fixedly mounted on the outer wall of the L-shaped rod 109, and a cleaning cylinder 111 disposed on the outer wall of the mounting plate 110. In a preferred embodiment: the corrugated telescopic tube 101, throttle valve 102, air pipe 103, one-way valve 104, sealing box 105, air nozzle 106, third spring 107, slide groove 108, L-shaped rod 109, and mounting plate 110 are considered as a set of movable components, and there are two sets of these movable components respectively arranged on both sides of the outer wall of the support frame 5. The throttle valve 102 is connected to the air inlet of the corrugated telescopic tube 101, and one end of the air pipe 103 is connected to the corrugated telescopic tube 101. The outlet of the tube 101 is connected to the air outlet, and the other end is connected to the air inlet of the sealing box 105. The inner cavity of the corrugated telescopic tube 101 is provided with a piston plate, and the third spring 107 is located at the bottom of the piston plate. One end of the third spring 107 overlaps with the inner wall of the corrugated telescopic tube 101, and the other end overlaps with the piston plate. One end of the L-shaped rod 109 is connected and fixed to the top of the corrugated telescopic tube 101, and the other end is slidably fitted against the inner wall of the slide groove 108. In the above structure, by pulling down the mounting plate 110, the mounting plate 110 slides along the inner wall of the slide groove 108 via the L-shaped rod 109. The sliding mounting plate 110 also synchronously drives the cleaning cylinder 111 and the corrugated telescopic tube 101 to undergo compression and displacement. When the corrugated telescopic tube 101 is compressed, the piston plate inside the corrugated telescopic tube 101 pushes the third spring 107 at the bottom to compress it. At this time, when the corrugated telescopic tube 101 is compressed, the throttle valve 102 closes the air inlet, causing the gas inside the corrugated telescopic tube 101 to be compressed under the pressure of the piston plate on the inner wall of the corrugated telescopic tube 101. The compressed gas is then transported through the air pipe 103 and the one-way valve 104 to the inner cavity of the sealing box 105, allowing the gas inside the sealing box 105 to pass through the air pipe 103. The nozzle 106 sprays air onto the end face of the control panel 3, blowing away the dust on the end face of the control panel 3. At the same time, when the corrugated telescopic tube 101 is compressed, the cleaning cylinder 111 will slide along with the mounting plate 110, and the outer edge of the cleaning cylinder 111 will contact the end face of the control panel 3 to further clean the dirt on the end face. At this time, after the cleaning cylinder 111 slides to the final end, the mounting plate 110 is released, and the mounting plate 110, the cleaning cylinder 111, the L-shaped rod 109, and the corrugated telescopic tube 101 are reset upward by the rebound of the third spring 107. When the corrugated telescopic tube 101 is reset, its inner cavity is in a negative pressure state, so that the throttle valve 102 opens and replenishes the inner cavity of the corrugated telescopic tube 101 with external gas, thereby achieving pressure balance.

[0020] Working principle: First, using the main housing 1 as a reference, the positioning groove 4 on the side wall of the operation panel 3 is aligned with the positioning pin 2 on the side wall of the main housing 1 and pushed in. During this process, the inner wall of the positioning groove 4 first contacts the spherical structure at the top of the first convex pin 902, causing the bottom of the first convex pin 902 to slide along the inner wall of the circular groove 6 under its pressure. Simultaneously, the first spring 901 is compressed, causing the first convex pin 902 to retract into the inner cavity of the circular groove 6. At this time, after the operation panel 3 is completely attached to the outer wall of the main housing 1, the positioning groove 4 is completely attached to the outer wall of the positioning pin 2, so that the first convex pin 902 corresponds to the inner wall of the first slot 7. The first convex pin 902 rebounds by utilizing the first spring 901 compressed at the bottom. The first convex pin 902 is repositioned into the inner cavity of the first slot 7. During this process, the spherical top of the first convex pin 902 contacts the bottom of the inclined end of the second convex pin 904. Under the pressure of the first convex pin 902, the other end of the second convex pin 904 slides along the inner wall of the guide groove 8, simultaneously compressing the second spring 905. When the top of the first convex pin 902 is fully inserted into the inner cavity of the first slot 7, the inclined end of the second convex pin 904 aligns with the inner wall of the second slot 903. At this point, the second convex pin 904 rebounds and inserts into the inner cavity of the second slot 903 using the compression of the second spring 905, thus strengthening the fixation of the first convex pin 902. This prevents it from loosening due to vibration. When disassembly is needed, pulling the connecting rod 906 causes the second convex pin 904 to slide along the inner wall of the guide groove 8. This sliding pin compresses the second spring 905, causing it to exit the inner cavity of the second slot 903. This releases the lock on the first convex pin 902. Then, pulling the operating panel 3 causes the first convex pin 902, due to its spherical top shape, to guide its arc surface against the arc surface of the first slot 7, causing it to exit the inner cavity of the first slot 7. At this point, the first convex pin 902 will be subjected to its... The inner wall of the positioning groove 4 is pressed, causing the bottom of the first convex pin 902 to slide along the inner wall of the circular groove 6 again. At this time, the first spring 901 will also re-enter the compressed state, so that after the positioning groove 4 is completely separated from the outer wall of the positioning pin 2, it will release the second slot 903, and the second convex pin 904 will be reset by the rebound of the second spring 905. At the same time, after the inner wall of the positioning groove 4 is no longer pressed, the first convex pin 902 will be reset by the rebound of the first spring 901, and so on, returning to the initial state, thereby improving the efficiency of maintenance. Secondly, when dust or stains accumulate on the end face of the operation panel 3, the mounting plate 110 is pulled down, so that the mounting plate 110 will slide along the inner wall of the slide groove 108 via the L-shaped rod 109.The sliding mounting plate 110 also synchronously drives the cleaning cylinder 111 and the corrugated telescopic tube 101 to undergo compression and displacement. When the corrugated telescopic tube 101 is compressed, the piston plate inside the corrugated telescopic tube 101 pushes the third spring 107 at the bottom to compress it. At this time, when the corrugated telescopic tube 101 is compressed, the throttle valve 102 closes the air inlet, so that the gas inside the corrugated telescopic tube 101 is compressed by the piston plate inside the corrugated telescopic tube 101. The compressed gas is then transported through the air pipe 103 and the one-way valve 104 to the inner cavity of the sealing box 105. The gas inside the sealing box 105 is then sprayed onto the end face of the operation panel 3 through the air nozzle 106. Dust on the surface is blown away by the gas. Simultaneously, as the corrugated telescopic tube 101 is compressed, its cleaning cylinder 111 slides along with the mounting plate 110. The outer edge of the cleaning cylinder 111 contacts the end face of the control panel 3, further cleaning the dirt on its end face. After the cleaning cylinder 111 slides to its final end, the mounting plate 110 is released, causing the mounting plate 110, cleaning cylinder 111, L-shaped rod 109, and corrugated telescopic tube 101 to return to their original position using the rebound of the third spring 107. Simultaneously, the inner cavity of the corrugated telescopic tube 101 is under negative pressure, causing the throttle valve 102 to open and replenish the inner cavity of the corrugated telescopic tube 101 with external gas, thus achieving pressure balance.
