[0026] Reference will now be made in detail to various embodiments of the invention, examples of which are presented in the accompanying drawings and described below. Although the invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the invention to these exemplary embodiments. Rather, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit of the invention and the scope defined by the appended claims.

[0027] The following is combined Figures 1 to 8 The backpack rack of the backpack-type home elevator of the present invention will be described.

[0028] Backpack-style home elevators typically consist of a backpack frame and a car for transporting people or goods. The backpack frame has a straight beam and horizontal forks, and the car is usually placed on the forks, with the car connected to both the straight beam and the forks.

[0029] like Figure 1 and Figure 2 As shown, the backpack frame of the backpack-type home elevator of the present invention includes: a straight beam 1 and two forks 2; wherein, the straight beam 1 includes two vertically extending columns 14; one end of each fork 2 extends horizontally from the bottom end of the corresponding column 14, and one end of the fork 2 is connected to one side of the bottom end of the corresponding column 14 by a tenon and mortise structure and fasteners.

[0030] The connection between the straight beam 1 and the fork 2 is improved by a mortise and tenon structure, and the connection strength is ensured by fasteners. Compared with welding, the connection between the straight beam 1 and the fork 2 in this invention is achieved through a mortise and tenon structure and fasteners, which simplifies the installation process while ensuring connection strength.

[0031] In an exemplary implementation, such as Figure 2 and Figure 3 As shown, the straight beam 1 includes a connecting plate 15, a connecting plate 16, and two vertical columns 14. The two ends of the connecting plate 15 are connected to the middle of the two columns 14, and the two ends of the connecting plate 16 are connected to the top of the two columns 14.

[0032] Each of the two vertical columns 14 has a mounting plate 11 on one side of its bottom, which is used to connect the fork 2.

[0033] In one embodiment, one side of the mounting plate 11 is fixed to the column 14 by means of welding or threaded connection, for example.

[0034] In another embodiment, the mounting plate 11 is integral with the column 14.

[0035] like Figure 3 As shown, the mounting plate 11 is provided with a connection hole 12, which is used together with the connection hole 214 (described later) to connect the straight beam 1 and the fork 2 with fasteners.

[0036] Fasteners can include shoulder bolts and spring pins.

[0037] The use of shoulder bolts and elastic pins as fasteners here is just an example; other fasteners, such as cylindrical pins, can also be used.

[0038] The mounting plate 11 has a slot 13 at its lower end near the fork 2 for connecting to the pallet body 221, which will be described later.

[0039] In an exemplary embodiment, two forks 2 are provided, each mounted to a corresponding mounting plate 11.

[0040] The fork 2 is L-shaped overall.

[0041] In an exemplary implementation, such as Figures 4 to 8 As shown, each fork 2 includes: a fork support 21 and a fork tray 22.

[0042] The fork support 21 has a horizontal support portion 211 and a vertical mounting portion 212 integrally formed. The mounting portion 212 is connected to the mounting plate 11 at the bottom end of the straight beam 1, and the bottom side of the mounting portion 212 away from the straight beam 1 is connected to one end of the support portion 211.

[0043] The mounting section 212 is provided with a mounting groove 213 for inserting the mounting plate 11.

[0044] The mounting groove 213 of the mounting part 212 is provided with a plurality of connection holes 214 communicating with the mounting groove 213. The position and number of connection holes 214 of each mounting part 212 correspond to the position and number of connection holes 12 on the corresponding mounting plate 11.

[0045] After the mounting plate 11 of the straight beam 1 is inserted into the mounting groove 213 of the mounting part 212, fasteners are used to pass through the connecting hole 214 and the connecting hole 12 to ensure the connection strength.

[0046] The mounting part 212 is provided with a slot 215 facing the support part 211 on the side near the support part 211 (see also [reference]). Figure 5 The lower surface of the slot 215 is flush with the upper surface of the support 211 to ensure that the fork support plate 22 can be inserted into the slot 215.

[0047] The upper surface of the support 211 is provided with a plurality of bosses 216 (see details below). Figure 4 and Figure 5 The boss 216 is used to connect with the through hole 223, which will be introduced later.

[0048] In an exemplary embodiment, the entire fork support 21 consists of a support plate 217, a support plate 218, and a support frame 219.

[0049] Support plates 217 and 218 are arranged in parallel and connected by a support frame 219. The gap between the portions of support plates 217 and 218 located in the mounting portion 212 forms a mounting groove 213. That is, the portions of support plates 217 and 218 located in the mounting portion 212 respectively form the sidewalls of the mounting groove 213. Connecting holes 214 are provided on support plates 217 and 218.

[0050] like Figure 7 As shown, the support frame 219 includes a crossbar 2192 and an insertion portion 2191 perpendicular to the crossbar 2192. One end of the insertion portion 2191 is connected to the middle of the crossbar 2192. The insertion portion 2191 is inserted into the gap between the portion of the support plate 217 and the support plate 218 located in the support portion 211 and then connected to the support plate 217 and the support plate 218. One end of the crossbar 2192 is connected to the bottom surface of the support plate 217, and the other end of the crossbar 2192 is connected to the bottom surface of the support plate 218.

[0051] like Figure 8 As shown, the forklift pallet 22 includes a horizontal pallet body 221, and a vertical extension plate 222 extending downward is provided on one side of the pallet body 221. The extension plate 222 can enhance bending resistance.

[0052] The upper surface of the tray body 221 is provided with a plurality of through holes 223, the number of through holes 223 corresponding to the number of bosses 216, and each boss 216 is inserted into a corresponding through hole 223.

[0053] The back of the pallet body 221 is welded to the support part 211 to ensure connection strength.

[0054] When one end of the tray body 221 is inserted into the slot 215 of the mounting part 212 and the mounting plate 11 is inserted into the mounting groove 213 of the mounting part 212, one end of the tray body 221 is inserted into the slot 13.

[0055] The tray body 221 is provided with a slot 224 and a slot 225 at the position where it connects to the mounting part 212, and the part between the slot 224 and the slot 225 is a plug-in part 226.

[0056] While one end of the pallet body 221 is inserted into the slot 215 of the mounting part 212, the portion of the support plate 217 of the fork support 21 located in the mounting part 212 (i.e., the side wall of the first side of the mounting groove 213) is inserted into the slot 224, the portion of the support plate 218 of the fork support 21 located in the mounting part 212 (i.e., the side wall of the second side of the mounting groove 213) is inserted into the slot 225, and after the mounting plate 11 is inserted into the mounting groove 213 of the mounting part 212, the insertion portion 226 of the pallet body 221 is inserted into the slot 13.

[0057] The assembly sequence of the backpack rack for the aforementioned backpack-style home elevator is as follows:

[0058] Insert one end of the pallet body 221 of the fork support plate 22 into the slot 215 of the mounting part 212 of the fork support 21, and at the same time, insert the boss 216 of the support part 211 into the through hole 223 of the pallet body 221 of the fork support plate 22.

[0059] The back of the pallet body 221 of the fork support plate 22 is welded together with the support part 211 to assemble the fork support 2.

[0060] The mounting slot 213 of the fork 2 is snapped into the mounting plate 11 of the straight beam 1, and the connecting hole 214 of the mounting part 212 is aligned with the connecting hole 12 on the mounting plate 11.

[0061] Fasteners are used to pass through connecting holes 214 and 12 to connect the mounting part 212 and the mounting plate 11, thereby enabling the fork 2 to be mounted to the bottom end of the straight beam 1.

[0062] The present invention provides an elevator equipped with a car and a backpack frame of the aforementioned backpack-type home elevator, wherein the car is supported on the fork 2 of the backpack frame, and the car is simultaneously connected to the straight beam 1 and the fork 2.
