DETAILED DESCRIPTION

[0018] The following will be combined with 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 the embodiments. Based on the embodiments in 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. Example

[0019] See also Figures 1 to 5 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: an elevator control device, comprising an elevator control panel body 1 and a plurality of floor buttons 2 arranged on the front surface of the elevator control panel body 1, and also comprising a sound hole square plate 5 with a plurality of through holes on the surface, a rectangular plate groove 11 corresponding to the sound hole square plate 5 is opened on the front surface of the elevator control panel body 1, a rectangular opening 12 communicating with the rectangular plate groove 11 is opened on the rear surface of the elevator control panel body 1, the sound hole square plate 5 is embedded and installed in the rectangular plate groove 11, and a disassembly mechanism 6 is arranged between the sound hole square plate 5 and the elevator control panel body 1;

[0020] The disassembly and assembly mechanism 6 includes an inner rotation groove 65 provided inside the elevator control panel body 1, an inner rotation seat 66 is rotatably installed in the inner rotation groove 65, a limit card strip 67 is welded and fixed on one side surface of the inner rotation seat 66, a card strip movable groove 69 for the limit card strip 67 to move is provided between the inner rotation groove 65 and the rectangular plate groove 11, and a strip card slot 68 corresponding to the limit card strip 67 is provided on both side surfaces of the sound hole square plate 5, and the end of the limit card strip 67 is screwed into the strip card slot 68, which can stably limit the sound hole square plate 5 and ensure the installation stability of the sound hole square plate 5. The disassembly and assembly mechanism 6 also includes a circular groove 61 provided on the front surface of the elevator control panel body 1, and the inner rotation seat 66 is viewed from above. It is T-shaped, and the front end of the inner rotating seat 66 penetrates the inner side of the circular groove 61 and is fixed with a dial bar 62. The subsequent operator can rotate the inner rotating seat 66 by pinching the dial bar 62 to realize the rotation of the limit card strip 67 into or out of the bar-shaped card slot 68. The disassembly and assembly mechanism 6 also includes a snap-fit ​​positioning structure, which is arranged between the inner rotating groove 65 and the inner rotating seat 66. The snap-fit ​​positioning structure includes a side groove 610, a spring 611, a telescopic card bead 612 and a circular card slot 613. The side groove 610 is arranged inside the elevator control panel body 1 and is located on one side of the inner rotating groove 65. The telescopic card bead 612 is movably installed in the side groove 610 through the spring 611. The surface of the inner rotating seat 66 is provided with three The three circular card slots 613 are evenly distributed, so that after the inner rotating seat 66 rotates ninety degrees, the end of the telescopic card bead 612 will be re-engaged in a circular card slot 613, so that the inner rotating seat 66 and the limiting card strip 67 are locked and positioned after rotation, and the limiting card strip 67 is guaranteed to limit the stability of the sound hole square plate 5. If the sound hole square plate 5 needs to be removed for cleaning and maintenance later, it is only necessary to rotate the pick 62 first, so that the inner rotating seat 66 squeezes the end of the telescopic card bead 612 into the side groove 610 first, so as to realize the smooth engagement of the inner rotating seat 66 and the limiting card strip 67. The limit card strip 67 is rotated smoothly, so that the limit card strip 67 can be gradually rotated out of the bar slot 68, until the pick 62 rotates ninety degrees with the inner rotating seat 66, the limit card strip 67 will be completely in the card strip movable slot 69, and no longer limit the sound hole square plate 5. At this time, the end of the telescopic card bead 612 will also be pushed by the spring 611 to be stuck in another circular slot 613. Therefore, the limit card strip 67 no longer limits the sound hole square plate 5, and the sound hole square plate 5 can be directly taken out from the rectangular plate slot 11, so as to deeply clean the through holes on the surface of the sound hole square plate 5, thereby improving the convenience of later maintenance, without the need to remove the entire elevator control panel body 1 from the inner wall of the elevator car, thereby improving the convenience of maintenance.

[0021] One end of the spring 611 is fixed on the inner wall of the side groove 610 , and the other end of the side groove 610 is fixedly connected to the telescopic card bead 612 to ensure the installation stability of the side groove 610 .

[0022] Among them, an emergency button 3 is arranged on the front surface of the elevator control panel body 1 relative to the top of the floor button 2, and a door operation button 4 is arranged on the front surface of the elevator control panel body 1 relative to the bottom of the floor button 2. Example

[0023] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the auxiliary positioning structure can be set to play an auxiliary positioning effect during the installation of the sound hole square plate 5, thereby further improving the installation convenience of the sound hole square plate 5.

[0024] Specifically, the disassembly and assembly mechanism 6 also includes an auxiliary positioning structure, which is arranged on the rear surface of the sound hole square plate 5. The auxiliary positioning structure includes a rubber plug 63 and a triangular clamping block 64. Two rubber plugs 63 are symmetrically glued and fixed on the rear surface of the sound hole square plate 5. The ends of the rubber plugs 63 pass through the rectangular opening 12 to the rear surface of the elevator control panel body 1, and the end surface of the rubber plug 63 is provided with a triangular clamping block 64. The triangular clamping block 64 is clamped on the rear surface of the elevator control panel body 1, so that the sound hole square plate 5 is installed at the initial stage when the operator pushes the sound hole square plate 5 into the After the rectangular plate groove 11 is inserted, the rear end of the rubber plug 63 will penetrate to the rear surface of the elevator control panel body 1, and the triangular clamping block 64 will be stuck on the rear surface of the elevator control panel body 1. At this time, the sound hole square plate 5 will be limited to prevent the sound hole square plate 5 from falling off at this time, and then the operator can achieve stable limiting of the sound hole square plate 5 by rotating the pick 62 to complete the installation of the sound hole square plate 5. The rubber plug 63 and the triangular clamping block 64 here play an auxiliary positioning effect during the installation process of the sound hole square plate 5, further improving the installation convenience of the sound hole square plate 5.

[0025] Among them, the rubber plug 63 and the triangular clamp block 64 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed. A cavity corresponding to the position of the triangular clamp block 64 is opened in the rubber plug 63, so that the triangular clamp block 64 has sufficient deformation space when squeezed.
