[0002] With the improvement of home environment and the enrichment of people's lives, home elevators have begun to be equipped in large numbers in residential buildings, especially for multi-story villas. Due to the limited space in private homes, concrete elevator shafts are generally not reserved. Most owners will choose to install the elevator in the middle of the stairs or near the stairs. At the same time, in order to reduce the impact of the elevator on lighting, it is necessary to install a sightseeing elevator, that is, a shaft frame that can install glass is required. There are currently two ways to install the shaft frame glass on the market. One is to install the glass from the inside of the frame, and the other is to install the glass from the outside of the frame. Both methods have their limitations. When installing the glass from the inside of the frame, the glass needs to be installed first and then the shaft components are installed. It is very easy to break the glass, and the subsequent replacement of the self-exploding glass requires the removal of the corresponding shaft components, and the maintenance cost is extremely high; when installing the glass from the outside of the frame, the glass can be installed after the shaft components are installed, but in some scenarios, additional scaffolding is required, such as the elevator is not in the middle or near the stairs, and some scenarios will make the glass impossible to install or inconvenient to install, such as the elevator has one or more sides against the wall.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figure 1 As shown, an elevator frame 100 in an embodiment of the present invention comprises a column 10, a cross bar 20, a column clamping strip 30 and a cross bar cover plate 40. A plurality of parallel columns 10 enclose a rectangular frame, the interior of which is an elevator shaft; a plurality of cross bars 20 are connected between adjacent columns 10 at both ends to improve the stability of the entire elevator frame 100, and a rectangular space is formed between adjacent columns 10 and cross bars 20 for installing glass 70; the column clamping strip 30 is detachably fixed to the column 10, and a first clamping groove 14 is formed between the column 10 and the column 10 to clamp the glass 70 from the side of the column 10; and the cross bar cover plate 40 is detachably fixed to the cross bar 20, and a second clamping groove 24 is formed between the cross bar 20 and the cross bar 20 to clamp the glass 70 from the side of the cross bar 20.

[0032] During installation, the glass 70 is first moved close to the installation position on the column 10 and the cross bar 20, and then the column clamping strip 30 and the cross bar cover plate 40 are fixed to the column 10 and the cross bar 20 respectively. At this time, the edge of the glass 70 is located in the first clamping groove 14 formed by the column 10 and the column clamping strip 30, and the second clamping groove 24 formed by the cross bar 20 and the cross bar cover plate 40. When the column clamping strip 30 and the cross bar cover plate 40 are completely fixed, the fixing operation of the glass 70 is also completed simultaneously. Since the glass 70 is fixed to the column 10 and the cross bar 20 by clamping, the glass 70 can be installed from the inside or outside of the hoistway, which improves the flexibility of installation and can be selected according to the actual situation such as the elevator installation position. In addition, the clamping installation method is relatively simple, which is convenient for later disassembly and maintenance.

[0033] In one embodiment, the columns 10 and the crossbars 20 are made of aluminum profiles (other materials may also be used), and a plurality of through cavities are formed on the surface or inside of the two. Since the elevator is convenient for transfer between different floors, it will at least pass through two floors in the height direction. If it is installed in a multi-story building, the overall length will be longer. In order to facilitate handling and transportation, the length of the columns 10 is moderate, and the elevator frame 100 is formed by connecting multiple columns 10 in height. A plurality of latches are provided at the connection between adjacent columns 10, such as Figure 2 As shown in FIG. 1 , a cylindrical pin 51 and a long pin 52 are inserted into cavities of different shapes in the column 10 .

[0034] The cavity into which the long pin 52 is inserted is a non-sealed cavity, which is a groove opened on the inner surface of the wellbore on the column 10. In order to prevent the long pin 52 from shifting and affecting the stability between the columns 10, a hole is opened on the surface of the long pin 52 and a fixing screw 53 is inserted. The tail of the fixing screw 53 is pressed against the surface of the column 10, thereby fixing the long pin 52 at the connection between the two columns 10.

[0035] The cross bar 20 can be fixed at the middle position of the column 10, or can be fixed at the connection between two columns 10. Figure 2 As shown, the end opening of the cross bar 20 is fixed to the connection between the two columns 10 by bolting, wherein the bolts include a first bolt 54 which is passed through the openings of the cross bar 20 and the long pin 52, and a second bolt 55 which passes through the opening of the cross bar 20 and is directly drilled into the column 10. This connection method further improves the stability of the connection between the two columns 10 while fixing the cross bar.

[0036] Figure 5 It is a cross-sectional view after the column 10 and the column clamping strip 30 are connected. The column 10 is set at the corner of the elevator frame 100, and the main cross section is L-shaped. The glass 70 is fixed to the two ends of the column 10. The end surface of the column 10 is provided with a first supporting surface 11 facing the inner side of the hoistway, and the column clamping strip 30 is provided with a first clamping portion 31 facing the first supporting surface 11. The first clamping groove 14 is formed between the first clamping portion 31 and the first supporting surface 11. When the column clamping strip 30 is fixed to the column 10, the edge of the glass 70 is fixed to the first supporting surface 11 by the first clamping portion 31. It is easy to think that the column clamping strip 30 is a long strip extending between the two cross bars 20. Of course, the length of the column clamping strip 30 can also be shortened, and it can be dispersedly set at the two ends and the middle position of the glass 70.

[0037] like Figure 5-7 As shown, two first buckling parts 32 are provided on the column clip 30, and correspondingly, two first buckling grooves 12 for accommodating the first buckling parts 32 are provided on the column 10. At the same time, a first blocking part 33 protrudes from at least one of the two first buckling parts 32, and a second blocking part 13 matching with the first blocking part 33 protrudes from the side wall of the first buckling groove 12 accommodating the first buckling part 32. Therefore, after the first buckling part 32 is inserted along the direction of the two first buckling grooves 12, the first blocking part 33 and the second blocking part 13 cooperate with each other to fix the column clip 30 at this position, so as to prevent it from being separated from the column 10 and affecting the stability of the glass 70.

[0038] Preferably, inclined surfaces are formed at the ends of the first blocking portion 33 and the second blocking portion 13 respectively to provide guidance when inserting and fixing the column clip 30 so that the first buckling portion 32 thereof can be smoothly inserted into the corresponding first buckling groove 12 .

[0039] For example, Figure 5 In the embodiment, one of the two first buckling grooves 12 is located in the middle of the column 10, and the other is located at the outer edge of the column 10. Due to structural reasons, the first buckling groove 12 at the outer edge is more likely to deform, so the first blocking portion 33 is set on the first buckling portion 32 at the outer edge. The first buckling groove 12 at the middle position and the first buckling portion 32 corresponding thereto are mainly used to prevent the column clip 30 from tilting on this side, and the two are not provided with a blocking structure to prevent separation, so as to avoid the situation where the column clip 30 cannot be normally separated when the glass 70 needs to be disassembled for maintenance or replacement.

[0040] It is easy to imagine that in order to prevent the glass 70 from shaking, after the glass 70 is placed and the column clamping strip 30 is fixed, the rubber strip 60 is squeezed between the first clamping portion 31 and the glass 70 to eliminate the gap between the glass 70 and the column 10 and the column clamping strip 30 to prevent the glass 70 from shaking. At the same time, the contact area between the glass 70 and the first clamping portion 31 is increased, and the glass 70 is prevented from breaking due to the flexible material of the rubber strip 60.

[0041] like Figure 5 , 10 As shown, the main body of the rubber strip 60 is triangular, and its bottom surface contacts the glass 70, and one side surface is provided with a groove for accommodating the side surface of the glass 70. When in use, the bottom surface of the rubber strip 60 is placed on the glass 70, and the side surface of one side of the groove is pressed against the first holding portion 31, and the rubber strip 60 is continuously moved until the side surface of the glass 70 moves into the groove of the rubber strip 60.

[0042] Similar to the fixing of the glass 70 by the column 10 and the column clamping strip 30, a second supporting surface 41 facing the inner side of the shaft is provided on the cross baffle cover 40, and a second clamping portion 21 facing the second supporting surface is correspondingly provided on the cross baffle 20, and a second clamping groove 24 is formed between the second clamping portion 21 and the second supporting surface 41, and the two cooperate to fix the glass 70.

[0043] To facilitate disassembly and maintenance, the cross bar 20 and the cross bar cover plate 40 are also fixed by snap fastening. Fig.10 , 11 As shown, a second buckling groove 22 with an opening facing upwards protrudes from the outer side of the cross bar 20, and a second buckling portion 42 correspondingly protrudes from the side of the cross bar cover plate 40 facing the cross bar 20. When installing, the second buckling portion 42 is inserted into the second buckling groove 22 from top to bottom, so that the cross bar cover plate 40 can be fixed on the cross bar 20. The second buckling groove 22 can be a long strip groove extending along the length direction of the cross bar 20, and in order to improve the stability during fixing, two second buckling grooves 22 are provided on the cross bar 20 up and down, thereby preventing the cross bar cover plate 40 from shaking.

[0044] In other embodiments, the second buckling groove 22 can be a smaller groove. To improve stability, multiple second buckling grooves 22 can be provided in the length direction of the cross bar 20 to form a buckling groove group, and two groups of second buckling grooves 22 can be provided in the vertical direction to prevent the cross bar cover plate 40 from shaking.

[0045] exist Fig.10 , 11 In the illustrated embodiment, two second buckling grooves 22 are provided on the cross bar 20 , and correspondingly two second buckling portions 42 are provided on the cross bar cover plate 40 to improve the stability of the cross bar cover plate 40 fixed to the cross bar 20 and prevent the cross bar cover plate 40 from shaking.

[0046] Preferably, in order to improve the success rate of inserting the second snapping portion 42 into the second snapping groove 22, matching inclined surfaces are provided at the end of the second snapping portion 42 and the end of the second snapping groove 22 close to the side wall on the outside of the well to provide guidance during insertion.

[0047] In order to improve the stability of the cross baffle cover 40 fixed on the cross baffle 20 and prevent the cross baffle cover 40 from shaking, a supporting portion 23 is protruded from the side of the cross baffle 20 facing the outside of the shaft. The supporting portion 23 defines the position of the cross baffle cover 40 when the second snap-fitting portion 42 is inserted into the second snap-fitting groove 22. The supporting portion 23 can abut and push the cross baffle cover 40 outward, and press the second snap-fitting portion 42 against the side wall of the second snap-fitting groove 22 on the side outside the shaft.

[0048] Preferably, a supporting portion 23 is provided on both sides of the second snap-fitting groove 22, and similar to the second snap-fitting groove 22, the supporting portion 23 can be a strip-shaped protrusion extending along the length direction of the cross bar 20. Of course, its length can also be shortened to a single small protrusion, and a plurality of protrusions can be provided in the length direction of the cross bar 20 to form a protrusion group.

[0049] Furthermore, a third blocking portion 43 is provided on the cross-bar cover plate 40, and the third blocking portion 43 protrudes from the surface of the cross-bar cover plate 40 facing the cross-bar 20, and is located below the abutting portion 23 and abuts against the abutting portion 23 when the cross-bar cover plate 40 is in the inserted state. Therefore, after the cross-bar cover plate 40 is fully inserted, the abutting portion 23 moves to the bottom of the abutting portion 23, thereby improving stability and preventing the cross-bar cover plate 40 from accidentally detaching from the cross-bar 20.

[0050] Since the third blocking portion 43 protrudes from the surface of the cross baffle cover plate 40 facing the cross baffle, in order to avoid interference with the abutting portion 23 and affecting the insertion of the second snap-fitting portion 42, an inclined surface is also provided at the lower end of the third blocking portion 43. When the third blocking portion 43 continues to move downward after contacting the abutting portion 23, the cross baffle cover plate 40 is slightly deformed and bends outward until the third blocking portion 43 moves to the bottom of the abutting portion 23 and then restores its deformation.

[0051] Similarly, a rubber strip 60 is provided between the glass 70 and the cross bar 20 , and the rubber strip 60 is inserted into the glass 70 after the glass 70 is installed in place to prevent the glass 70 from breaking.

[0052] Here, the elevator frame 100 in this embodiment is further explained in combination with a specific construction scenario.

[0053] After the elevator installation location is selected, the column 10 is fixed by the cylindrical pin 51 and the long pin 52, and the crosspiece 20 is fixed to the column 10 to form the main part of the elevator frame 100. Then, according to the location environment, the glass 70 is installed between the column 10 and the crosspiece 20 from the inside or outside, such as Figure 3 and Figure 8 As shown, install the glass from the outside of the shaft, or Figure 4 and Fig. 9 The glass is installed from the inside of the shaft and finally the rubber strip 60 is inserted.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
