Description
Technical Field
[0001] This utility model relates to the field of threshold installation technology, and in particular to a threshold installation component for floor doors. Background Technology
[0002] A landing sill is a grooved metal step used for entering and exiting an elevator car or landing door. It is a very important component of elevator structures. The landing sill ensures the normal operation of the landing door by fixing its movement path. The installation of the landing sill usually involves setting up a groove at the elevator landing door and installing the landing sill in the groove using mounting components so that the surface of the sill is approximately the same height as the floor surface.
[0003] In the existing technology, the installation components of the middle-floor door sill usually include a mounting bracket, expansion bolts, and mounting bolts. One side of the mounting bracket is fixedly connected to the bottom wall of the sill by mounting bolts, and the other side of the mounting bracket is fixedly set on the inner wall of the sill installation channel by expansion bolts, thus completing the sill installation.
[0004] However, in actual use, people enter and exit the elevator, and the sill surface is often subjected to great pressure. The pressure acting on the support can easily cause the support to break. The sill has limited pressure resistance, which leads to certain safety risks. Utility Model Content

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0032] This application discloses an installation assembly for a door sill 3. (Refer to...) Figures 1 to 2It includes multiple sets of first mounting blocks 1, second mounting blocks 2, and connecting components 4. The first mounting block 1 consists of two sets of first assembly plates 11 and two sets of second assembly plates 12. The first assembly plates 11 and second assembly plates 12 are fixedly and vertically welded together. A first connecting block 14 is fixedly disposed between the two second assembly plates 12. The first connecting block 14 is L-shaped and fixedly connects the two sets of second assembly plates 12, while also fixing the two sets of first assembly plates 11. The second mounting block 2 is assembled from two sets of third assembly plates 21 and two sets of fourth assembly plates 22. The third assembly plates 21 and fourth assembly plates 22 are fixedly and vertically welded together. An L-shaped second connecting block 24 is disposed between the two third assembly plates 21, fixing the two sets of third assembly plates 21, while also fixing the two sets of fourth assembly plates 22. The connecting component 4 is used to connect the second assembly plates 12 and the third assembly plates 21. Both the second assembly plates 12 and the third assembly plates 21 have reinforcing ribs 131 along their length. The connecting component 4 shares the pressure borne by the first mounting block 1 and the second mounting block 2, and at the same time, the reinforcing rib 131 increases the strength of the first mounting block 1 and the second mounting block 2, thereby reducing the possibility of damage and breakage of the first mounting block 1 and the second mounting block 2 during use and reducing safety risks.
[0033] To further enhance the strength, refer to Figures 1 to 2 The first assembly plate 11 fits against the bottom wall of the sill 3. The first assembly plate 11 is equipped with mounting bolts 15, which, in conjunction with nuts, secure the first assembly plate 11 to the bottom wall of the sill 3. The fourth assembly plate 22 fits against the inner wall of the channel. The fourth assembly plate 22 is equipped with expansion bolts 25, which are used to secure the fourth assembly plate 22 to the inner wall of the channel. In this embodiment, the sill 3 is bolted to an outer baffle 31. L-shaped first reinforcing blocks 13 are fixedly installed on both outer walls of the first assembly plate 11, and are fixedly connected to the outer walls of the second assembly plate 12. L-shaped second reinforcing blocks 23 are installed on both outer walls of the fourth assembly plate 22, and are fixedly connected to the outer walls of the third assembly plate 21. The first reinforcing blocks 13 enhance the strength at the connection between the first assembly plate 11 and the second assembly plate 12, and the second reinforcing blocks 23 enhance the strength at the connection between the third assembly plate 21 and the fourth assembly plate 22, thereby reducing the safety risk of breakage.
[0034] For ease of assembly, refer to Figure 2The connecting assembly 4 includes two sets of connecting bolts 41 and two sets of connecting nuts 42. Each of the second assembly plates 12 has a first connecting groove 111 extending along its length, and each of the third assembly plates 21 has a second connecting groove 211 extending along its length. The second assembly plates 12 and 21 are perpendicularly arranged and fit together, allowing the first connecting groove 111 to connect to the second connecting groove 211 in two places. The second assembly plate 12 is arranged vertically, and the third assembly plate 21 is arranged horizontally. The connecting bolts 41 pass through the first connecting groove 111 and the second connecting groove 211, with the nuts of the connecting bolts 41 abutting against the third assembly plate 21. The connecting nuts 42 are fitted onto the connecting bolts 41 and threadedly connected to them, abutting against the second assembly plate 12. The connecting nuts 42 and the connecting bolts 41 facilitate the assembly or disassembly of the second assembly plate 12 and the third assembly plate 21.
[0035] To improve the stability of the assembly connection, refer to Figure 2 and Figure 3 The first connecting block 14 has a first sliding groove 141 along its length on the side near the third assembly plate 21, and the second connecting block 24 has a second sliding groove 241 along its length on the side near the second assembly plate 12. A connecting plug 5 is slidably disposed in the first sliding groove 141, and the connecting plug 5 is adapted to be inserted into the second sliding groove 241 and can slide within the second sliding groove 241. Extension blocks 51 are fixedly disposed on both sides of the connecting plug 5, adapted to be slidably inserted into the second sliding groove 241, and the extension blocks 51 abut against the inner wall of the second sliding groove 241. An auxiliary block 52 is fixedly disposed at the end of the extension block 51 away from the third assembly plate 21, and the auxiliary block 52 is adapted to pass through the first connecting groove 111 and can slide within the first connecting groove 111. The extension blocks 51 abut against the inner wall of the second sliding groove 241, thereby limiting the second assembly plate 12 and the third assembly plate 21, reducing the possibility of relative displacement due to twisting between the two, and improving the stability of the assembly connection.
[0036] The implementation principle of the door sill 3 installation assembly in this application embodiment is as follows: the first installation block 1 and the second installation block 2 are assembled by connecting bolts 41 and connecting nuts 42. The first installation block 1 and the second installation block 2 are both L-shaped structures and are respectively connected to the sill 3 and the inner wall of the channel. At the same time, the first reinforcing block 13 and the second reinforcing block 23 are reinforced by reinforcing ribs 131. The strength of the first installation block 1 and the second installation block 2 themselves, together with the connecting bolts 41, share the pressure, thereby reducing the possibility of breakage during use and reducing safety risks.
[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
