[0063] As Figure 1 , Figure 2A , Figure 5A and Figure 5B shown, the elevator call box according to the embodiment of the present invention includes: a base plate 100, a box body frame 200, a slider 300, and an elastic member 400.
[0064] As Figure 2A shown, the base plate 100 has side plates 101, and the side plates 101 have first hooks 102. The base plate 100 is fixed to the outer wall outside the elevator hall.
[0065] As Figure 3A shown, the box body frame 200 has a bottom plate 201 and side plates 203. As Figure 3D shown, the bottom plate 201 has a horizontal chute 202. As Figure 3C shown, the side plates 203 of the box body frame 200 have second hooks 204 corresponding to the first hooks 102.
[0066] The bottom of the slider 300 is slidably mounted to the chute 202.
[0067] As Figure 5A and Figure 5B shown, the elastic member 400 can provide an elastic force to the slider 300.
[0068] Wherein, when the box body frame 200 is installed on the base plate 100, under the action of an external force (the force applied by hand), the base plate 100 can withstand the slider 300, so that the slider 300 can compress the elastic member 400.
[0069] When the box body frame 200 slides down to the upper end surface of the slider 300 being flush with the lower end surface 103 of the base plate 100, the slider 300 slides under the action of the elastic force provided by the compressed elastic member 400 to below the base plate 100, thereby restricting the upward movement of the box body frame 200, and the first hook 102 and the second hook 204 can be interlocked, so that the box body frame 200 and the base plate 100 form front and rear limits, thereby fixing the box body frame 200.
[0070] The elastic force provided by the elastic member 400 in the implementation scheme of the present invention enables the slider 300 to slide under the substrate 100 when the upper end surface of the slider 300 is flush with the lower end surface 103 of the substrate 100, thereby locking the box frame 200, eliminating the need for screw fastening and making the operation more convenient.
[0071] In an exemplary implementation scheme, as Figure 2A shown, the substrate 100 includes a substrate body 106 and side plates 101.
[0072] The substrate body 106 extends in the up and down direction, and the substrate body 106 is installed on the outer wall outside the elevator hall. There are two side plates 101, and each side plate 101 extends forward from both sides of the substrate body 106.
[0073] In an exemplary implementation scheme, as Figure 2A shown, there are 3 first hooks 102 on each side plate 101, but the number can be adjusted according to the situation, for example, it can be set to any number from 2 to 5.
[0074] In an exemplary implementation scheme, as Figure 2B shown, the first hook 102 has a card slot 104, and the card slot 104 has a first inclined surface 105. The first inclined surface 105 extends in the upward and forward direction so that the second hook 204 can be more easily inserted into the card slot 104 to form front and rear limits.
[0075] In an exemplary implementation scheme, as Figure 3A and Figure 3B shown, the box frame 200 is generally in the shape of a cuboid. The box frame 200 includes a box body 208, two side plates 203, a bottom plate 201 and a top plate 213.
[0076] The box body 208 is generally in the shape of a plate and extends in the up and down direction. The two side plates 203 extend backward from the left and right sides of the box body 208. The bottom plate 201 extends backward from the lower edge of the box body 208. The top plate 213 extends backward from the lower edge of the box body 208.
[0077] The box body 208, the two side plates 203, the bottom plate 201 and the top plate 213 enclose a receiving space 214 to receive the display board 500 (see for reference Figure 5A ), the slider 300 and the elastic member 400 (see for reference Figure 5B ).
[0078] In an exemplary implementation scheme, as Figure 1 and Figure 3B shown, the box body 208 is provided with a first mounting opening 215, a second mounting opening 216 and a third mounting opening 217, as Figure 1As shown, the first mounting opening 215 is used to mount a light-transmitting plate to expose the display panel 500, the second mounting opening 216 is used to mount the first button 218, and the third mounting opening 217 is used to mount the second button 219. The first button 218 and the second button 219 are electrically connected to the internal circuit of the elevator call box. A passenger (or maintenance personnel) can summon an upward elevator by pressing the first button 218, and a passenger (or maintenance personnel) can summon a downward elevator by pressing the second button 219.
[0079] In an exemplary embodiment, as Figure 3A shown, there are 3 second hooks 204 provided on each side plate 203, but the number thereof can be adjusted according to circumstances, for example, it can be set to any number from 2 to 5.
[0080] In an exemplary embodiment, as Figure 3C 、 Figure 4A and Figure 4B shown, the second hook 204 has a second inclined surface 205 corresponding to the first inclined surface 105.
[0081] As Figure 3C shown, the shape of the second hook 204 is generally in a shape like ㄣ.
[0082] In the illustrated embodiment, the surfaces where the first hook 102 and the second hook 204 contact each other are inclined surfaces. In addition, the surfaces where the two contact each other can also be set to contact surfaces extending vertically.
[0083] In an exemplary embodiment, as Figure 3D and Figure 3E shown, the bottom plate 201 of the box body frame 200 has two first brackets 206, and the two first brackets 206 have guide grooves 207 facing each other to form the sliding groove 202, and the guide plate 301 of the slider 300 described later can slide back and forth along the guide groove 207.
[0084] In an exemplary embodiment, as Figure 3D and Figure 3E shown, the box body main body 208 of the box body frame 200 has a second bracket 209, and the second bracket 209 has a first strip-shaped hole 210, and the first strip-shaped hole 210 extends along the front-back direction, and the first strip-shaped hole 210 can limit the latch 303 of the slider 300 described later.
[0085] In an exemplary embodiment, as Figure 3D and Figure 3EAs shown, the housing body 208 of the housing frame 200 further has a receiving groove 211. The receiving groove 211 is provided below the second bracket 209. One end of the elastic member 400 abuts against the slider 300, and the other end of the elastic member 400 abuts within the receiving groove 211 (see the cooperation with Figure 5A and Figure 5B ), and a part of the elastic member 400 can be received within the receiving groove 211.
[0086] In an exemplary embodiment, as shown in Figure 5A , Figure 5B , Figure 5C and Figure 5D , the bottom plate 201 of the housing frame 200 has a second elongated hole 212. The second elongated hole 212 penetrates the bottom plate 201 in the up and down direction. Maintenance personnel can use a screwdriver or other tool to insert through the second elongated hole 212 and then into the bottom hole 302 of the slider 300 introduced later, so as to realize the disassembly of the housing frame 200.
[0087] In an exemplary embodiment, as shown in Figure 6A and Figure 6B , the bottom of the slider 300 has a guide plate 301 corresponding to the guide groove 207. The guide plate 301 can be slidably installed within the guide groove 207. In addition, the cooperation between the guide groove 207 and the guide plate 301 can prevent the slider 300 from moving relative to the housing frame 200 in the up and down direction.
[0088] In an exemplary embodiment, as shown in Figure 5A , Figure 5B , Figure 5C and Figure 5D , the bottom of the slider 300 has a bottom hole 302 with an opening downward. Maintenance personnel can use a screwdriver or other tool to insert through the second elongated hole 212 and then into the bottom hole 302 of the slider 300 to push the slider 300, so that the slider 300 moves forward relative to the substrate 100 and the housing frame 200, thereby realizing the disassembly of the housing frame 200.
[0089] In an exemplary embodiment, as shown in Figure 5B , Figure 5D , Figure 6A and Figure 6B , the top of the slider 300 has a latch 303 corresponding to the first elongated hole 210. The latch 303 is restricted within the first elongated hole 210.
[0090] In an exemplary embodiment, the elastic member 400 can be a spring. Here, the type of the elastic member 400 is not limited thereto, and it can be any form in the prior art as long as it can achieve the above functions.
[0091] The operation of the elevator call box according to the embodiments of the present invention will be described below with reference to the accompanying drawings.
[0092] Installation process:
[0093] Fix the substrate 100 on the outer wall outside the elevator hall, and make the side plate 101 of the substrate 100 face forward.
[0094] Align the box frame 200 with the substrate 100 approximately. At this time, due to the force applied by hand, the substrate 100 presses against the slider 300, compressing the elastic member 400; the second hook 204 of the box frame 200 is located above the first hook 102 of the substrate 100, and the upper end surface 304 of the slider 300 is higher than the lower end surface 107 of the substrate 100 (see the cooperation in Figure 5B ).
[0095] Pull down the box frame 200.
[0096] During the pulling-down process, the bottom of the second hook 204 is inserted into the slot 104 of the first hook 102.
[0097] When the box frame 200 drives the slider 300 to move down until the upper end surface 304 of the slider 300 is flush with the lower end surface 107 of the substrate 100, the first hook 102 and the second hook 204 are engaged with each other. At the same time, under the action of the elastic force provided by the compressed elastic member 400, the slider 300 pops out backward, so that the slider 300 is located below the substrate 100 (see the cooperation in Figure 5D ).
[0098] At this time, the rear end surface 220 of the second hook 204 contacts the substrate body 106, and the lower end surface 107 of the substrate 100 restricts the upward movement of the box frame 200 (see the cooperation in Figure 5D ), and the first hook 102 of the substrate 100 restricts the downward movement and forward movement of the second hook 204 of the box frame 200 (see the cooperation in Figure 4B ), thus restricting the downward movement, forward movement and backward movement of the box frame 200, and realizing the locking of the box frame 200.
[0099] Disassembly process:
[0100] The maintenance personnel use a screwdriver 600 or other tools to pass through the second strip hole 212 and insert into the bottom hole 302 of the slider 300, and push the slider 300 forward, so that the substrate 100 no longer restricts the upward movement of the slider 300 (see the cooperation in Figure 7A ).
[0101] Use a screwdriver 600 or other tools to push the slider 300 upward or continue to push it forward to push the box frame 200 upward and forward (see the cooperation in Figure 7B), so as to remove the box body frame 200 from the substrate 100.
