Background

In general, a connecting device for an elevator car wall plate (also called a car wall plate) includes a plurality of nuts provided separately and a plurality of screws used in cooperation with the nuts, and when two car wall plates are installed, it is necessary to separately position the nuts and screw down the screws, which consumes a lot of man-hours, especially when an elevator is installed on a delivery site, it is difficult for an installer to perform the above-mentioned operations due to a narrow elevator shaft space, and installation is difficult. In addition, in order to avoid deformation of the car wall plate caused by screw connection, the thickness of the side wall of the car wall plate needs to be increased.

In order to overcome the defects, some manufacturers assemble a plurality of nuts on the metal strip, and the metal strip is stuck on the side wall of the car wallboard by adopting the double-sided adhesive tape, so that the metal strip is only required to be positioned, each nut is not required to be positioned independently, and the nuts are only required to be connected by screws when the car wallboard is installed subsequently. However, this arrangement still has the following drawbacks:

1. the cost of the metal strip is high;

2. it is difficult to accurately position the metal strip, if the positioning is inaccurate, the metal strip needs to be removed and re-adhered to the car wall plate, which reduces the adhesive strength of the double-sided adhesive tape, and if the double-sided adhesive tape is replaced, the cost is further increased, and more installation time is consumed;

3. double-sided tapes generally contain formaldehyde and other components, causing environmental pollution.

Accordingly, those skilled in the art have been directed to developing a novel connection device that avoids the above-described drawbacks of the prior art.

Referring to fig. 1 to 5, the nut assembly 1 includes a body 2 and a plurality of nuts 3, and hereinafter, two nuts 3 are mainly described, but the disclosure is not limited thereto. The body 2 is substantially strip-shaped and comprises a first side wall 21 and a second side wall 22 which are arranged oppositely, and a third surface 23 and a fourth surface 24 which connect the two side walls 21, 22. The body 2 comprises a plurality of bosses 10 at the third surface 23, corresponding to the number of nuts 3, and each boss 10 is provided with an opening H through the body 2. The nuts 3 are disposed on the body 2, and the threaded holes thereof are aligned with the openings H, so that the nuts 3 are disposed only by positioning the body 2 when the nut assembly 1 is installed, without separately positioning each nut 3.

In a preferred embodiment, the nut 3 may be buried inside the body 2 (as shown in fig. 5), i.e. the body 2 is overmolded outside the nut 3, so as to avoid the problem that the nut 3 is located outside the body 2 or protrudes out of the body 2 and may be collided to cause it to be separated from the body 2.

Referring to fig. 1, 2 and 4, at least one protrusion 20 is disposed on the first side wall 21 of the body 2 and configured to abut against an inner wall of the side wall groove 51 when the nut assembly 1 is received in the side wall groove 51 (as shown in fig. 6) of the car wall plate 5, so as to fix the nut assembly 1 in the side wall groove 51. The arrangement does not need to use double-sided tape, thereby reducing the cost and avoiding environmental pollution. In a preferred embodiment, as shown in fig. 1 and 4, the protrusions 20 may be configured as wedge-shaped protrusions 20 extending substantially along the central axis of the opening H, that is, the size of the wedge-shaped protrusions 20 protruding from the first side wall 21 in the thickness direction X of the body is gradually increased so as to accommodate the nut assembly 1 in the side wall groove 51 of the car wall plate 5, and the clamping force of the side wall groove 51 to the nut assembly 1 may be increased with the increase of the accommodating depth, so that the nut assembly 1 is firmly mounted to the car wall plate 5. Of course, the present disclosure is not limited to the above-described structure, and the protrusion 20 may be a segment-shaped protrusion, for example, so long as the nut assembly 1 can abut against the sidewall groove 51 and be fixed in the sidewall groove 51 when being accommodated in the sidewall groove 51.

Preferably, as shown in fig. 1, 2 and 4, the wedge-shaped protrusion 20 may be disposed corresponding to the boss 10, that is, on the first side wall 21 at the boss 10 (may also be referred to as being located on the boss 10), so as to increase the extension length of the wedge-shaped protrusion 20 and increase the maximum size protruding from the first side wall 21, thereby more effectively fixing the nut assembly 1 to the car wall plate 5.

Referring to fig. 4 and 5, the second side wall 22 of the body 2 may be provided with at least one rough portion 30 for increasing the friction between the body 2 and the car wall 5 when the nut assembly 1 is received in the side wall groove 51, so that the nut assembly 1 can be more firmly mounted on the car wall 5 and is not easy to fall off. In an embodiment, the roughness 30 may be disposed corresponding to the boss 10, i.e., on the second sidewall 22 at the boss 10 (may also be referred to as being disposed on the boss 10), so as to increase the disposition area of the roughness 30 to increase the friction force. In an embodiment, the rough portion 30 may be, for example, in a zigzag shape, as shown in fig. 5, but the disclosure is not limited thereto, as long as the friction force between the body 2 and the car wall 5 can be raised when the nut assembly 1 is installed.

In order to quickly and accurately mount the nut assembly 1 at the correct position of the car wall plate 5, the body 2 of the nut assembly 1 may further include a first positioning portion 40, and correspondingly, a second positioning portion 51 (as shown in fig. 6) may be disposed on the car wall plate 5, and the nut assembly 1 may be quickly and accurately mounted at the correct position by aligning the first positioning portion 40 and the second positioning portion 51. In this embodiment, the first positioning portion 40 may be a positioning boss 40, and the positioning boss 40 may be provided with a positioning mark 41, for example, a positioning hole, a positioning groove, or a positioning protrusion. Correspondingly, the second positioning portion 51 is, for example, a positioning hole, a positioning protrusion, or a positioning groove. By aligning the two positioning holes or arranging the positioning protrusions in the positioning grooves, the nut component 1 can be quickly mounted at the correct position, and the mounting time is effectively shortened. In fig. 1, 2 and 6, the positioning mark 41 and the second positioning portion 51 are each exemplified by a positioning hole, but the present disclosure is not limited thereto.

In a preferred embodiment, the body 2 of the nut assembly 1 may be made of a non-metallic material. For example, the body 2 may be a plastic body made of engineering plastic ABS, a rubber body made of a rubber material, or a body made of other nonmetallic materials, so that the manufacturing cost of the nut assembly 1 can be effectively reduced. In addition, since the body 2 of the nut assembly 1 has a certain thickness, when the nut assembly 1 is installed and fixed in the sidewall groove 51 of the car wall plate 5, the body 2 can be used as the sidewall of the car wall plate 5, that is, the above arrangement of the nut assembly 1 can reduce the thickness of the original sidewall of the car wall plate 5, so as to reduce the manufacturing cost of the car wall plate.

Although the nut assembly 1 of the above embodiment is described with the body 2 including the boss 10 and the positioning boss 40, the disclosure is not limited thereto, and for example, the body 2 may be a strip-shaped body with a uniform thickness, and the same effects as described above may be achieved.
