[0006] In the utility model, the floor indication information of the elevator adopts the original display system, which is a monochrome white light LED lamp display, but at the display window, the utility model sets a panel with a colored semi-transparent film to cover the display window. After the monochrome white light passes through the mask of the colored semi-transparent film, the display becomes colorful. The panel is set in the installation groove, and the installation groove adopts a sheet metal part with a folded edge, which is aligned with the left and right sides and the bottom edge of the display window and welded outside the display window. Between the installation groove and the inner wall of the elevator, an installation space with an upper opening is formed. The mask plate slides into the installation space from the top, and can also be removed from the top and replaced with a new panel of other colors.
[0007] A blind hole is arranged at the portion of the mask plate higher than the display window, and the blind hole is hidden from the passenger's perspective. A through hole is arranged at the position of the blind hole corresponding to the inner wall of the elevator, and a locking device is arranged behind the inner wall of the elevator. The locking device includes a locking rod, and the locking rod passes through the through hole and reaches the bottom of the blind hole. When the locking rod is not separated from the blind hole, the mask plate cannot be separated upward from the installation space. The beneficial effects are simple structure, low manufacturing cost, convenient panel replacement, and not easy to be lost intact after installation.
[0008] Furthermore, the lock device also includes a connecting arm rod as a lever arm, one end of the connecting arm rod is connected to the lock rod, and the lock rod faces the through hole of the elevator inner wall; the other end of the connecting arm rod is connected to a metal block, the metal block has a magnetic property, which is called a magnetic switch member, the magnetic switch member faces the elevator inner wall, and a gap is set between the lower end surface of the magnetic switch member and the elevator inner wall. The magnetic switch member moves downward to the elevator inner wall, and the distance the lock rod moves upward is greater than the depth of the blind hole of the mask plate; it also includes a mounting seat, the upper end of the mounting seat is provided with a rotating pin seat, the connecting arm rod is rotatably connected to the rotating pin seat through a rotating pin, and the lower end of the mounting seat is fixedly connected to the elevator inner wall; it also includes a spring member, one end of the spring member passes through the magnetic switch member and buckles on the connecting arm rod, and the other end buckles on the elevator inner wall, the elastic force of the spring member acts on the lock rod through the connecting arm rod to limit the lock rod from the blind hole of the mask plate.
[0009] In the utility model, the locking device includes an equal-arm lever, which is installed on the rotating pin seat of the mounting seat through a rotating pin, a locking rod is installed at one end of the equal-arm lever, and a metal block with magnetic attraction characteristics is installed at the other end. The locking rod passes through the through hole on the elevator inner wall to reach the bottom of the blind hole on the shielding plate, and there is a gap between the lower end of the metal block and the elevator inner wall. The metal block can be connected to the magnetic attraction part outside the elevator inner wall by magnetic force. When the magnetic force is connected, the metal block overcomes the elastic force of the spring part and moves toward the elevator inner wall. Through the lever effect, the locking rod moves in a direction away from the elevator inner wall, and then the locking rod is separated from the blind hole of the shielding plate. At this time, the shielding plate can move toward the top of the installation space until it is separated from the installation space. When the magnetic connection disappears, the metal block moves upward away from the elevator inner wall under the elastic force of the spring part. Through the lever effect, the locking rod moves in the direction of the blind hole of the shielding plate, and the shielding plate is locked in the installation space again.
[0010] Furthermore, the locking rod is made of aluminum alloy profile 6061; the connecting arm rod is made of aluminum alloy profile 6061; the mounting base is made of stainless steel 304; and the magnetic switch component is made of stainless steel 304.
[0011] In the utility model, the function of the locking rod is to lock the shield plate in the installation space to prevent it from being disassembled without loss. The locking rod needs to withstand the shear force when the shield plate moves upward. The shear force comes from manual force, so a lightweight aluminum alloy part with a certain strength can be used. The connecting arm acts in conjunction with the magnetic force to lift or press the locking rod, so a lightweight aluminum alloy part with a certain strength can be used. The connecting arm is installed at the upper end of the mounting seat, and the lower end is welded and fixed to the inner wall of the elevator, so stainless steel 304 is used. The magnetic switch is made of magnetic stainless steel 304 material, and 304 stainless steel can be attracted by a magnet to form a magnetic connection.
[0012] Furthermore, the non-magnetic stainless steel material is Mn13 non-magnetic steel.
[0013] In the utility model, the stainless steel material of the elevator inner wall is non-magnetic stainless steel material Mn13 non-magnetic steel. When the magnet approaches the elevator inner wall, the magnetic lines of force can pass through the Mn13 non-magnetic steel to act on the magnetic switch part of the locking device, thereby driving the magnetic switch part to move downward, and further linking the locking rod to disengage from the blind hole of the mask plate.
[0014] Furthermore, the installation groove is made of stainless steel 304 with a thickness of 2 to 4 mm.
[0015] In the utility model, the installation groove is made of stainless steel 304 material, which is convenient for welding the installation groove to the inner wall of the elevator. The plate thickness is 2-4 mm, which is suitable for fixing the shielding plate, while saving materials and reducing manufacturing costs.
[0016] Furthermore, the blind hole of the mask plate has a depth of 2 to 3 mm.
[0017] In the utility model, the blind hole depth of the shielding plate is 2-3 mm, which is sufficient for the locking rod to lock the shielding plate and is easy for the locking rod to be disengaged, thereby improving the reliability and convenience of releasing the shielding plate.
[0018] The utility model installs a mask plate on the outer side of the elevator inner wall, and improves the monotonous effect of the monochrome white light LED display by using a colored translucent film. The colored translucent film can be flexibly replaced according to design requirements, thereby realizing the personalized customization of the elevator display. A locking device is hidden on the inner side of the elevator inner wall. The locking device uses a locking rod to reach the blind hole of the mask plate to limit the lossless separation of the mask plate, and uses a magnetic attraction to unlock the mask plate to realize the replacement of the mask plate. Its beneficial effects also lie in its simple structure, low manufacturing cost, and good hidden installation effect. BRIEF DESCRIPTION OF THE DRAWINGS
