[0029] The first nut 5 is screwed in the vertical groove 11 and the first bolt 4 is screwed in the vertical groove 11 to prevent the first bolt 4 from being screwed in the vertical groove 11.

[0030] Furthermore, the transverse portion 32 is engaged in the outer transverse groove 22 and adopts the second bolt 6 threadedly engaged with the second nut 7 located in the inner transverse groove 21. The connection position protrusion between the inner transverse groove 21 and the outer transverse groove 22 is provided with two transverse limiting portions 23 which are clamped by the transverse portion 32 and the second nut 7 when the second bolt 6 is tightened. The two transverse limiting portions 23 are symmetrically arranged, and a transverse insertion opening is formed between the two transverse limiting portions 23 to at least avoid the screw rod of the second bolt 6, so that the screw rod of the second bolt 6 can be inserted into the inner transverse groove 21 and threadedly engaged with the second nut 7 to complete the fixed positioning of the connecting member 3 and the beam profile 2, which not only fixes the column profile 1 and the beam profile 2 together, but also hides the second bolt 6, the transverse portion and the second nut 7 in the transverse connecting groove, reduces the interference of external factors on the second bolt 6, the transverse portion and the second nut 7 and other components, and ensures their service life.

[0031] The connecting member 3 of this embodiment includes a vertical portion 31 and a transverse portion 32, wherein the vertical portion 31 is hidden and fixed in the vertical connecting groove of the column profile 1 by a first bolt 4 and a first nut 5, and the transverse portion 32 is hidden and fixed in the transverse connecting groove of the beam profile 2 by a second bolt 6 and a second nut 7, thereby achieving the purpose of completely hiding the connecting member 3 and its fasteners in the column profile 1 and the beam profile 2, not only avoiding external exposure and improving the overall aesthetics of the elevator shaft frame, but also using the hidden design to reduce the interference of external factors such as moisture and dust on the connecting member 3 and its fasteners, effectively extending the service life of the components, while enhancing the overall stability of the shaft frame structure and ensuring the safety of elevator operation.

[0032] In this embodiment, the cross-sectional shape of the column profile 1 when viewed from above is L-shaped. The column profile 1 includes two column connecting portions 101 connected in an L-shape, each of which is provided with a vertical slot structure. Furthermore, the vertical slot structure includes a vertical slot 14 disposed adjacent to the vertical connecting slot. The vertical slot 14 is used to insert the end of the glass to facilitate installation of the glass on the derrick. The vertical slot 14 is located near the front of the column connecting portion 101, while the vertical connecting slot is located near the back of the column connecting portion 101. In addition, a plurality of column outer grooves 102 are provided on the front of the vertical connecting portion. The column outer grooves 102 can enhance the strength and stability of the column profile 1, thereby ensuring the operational stability of the derrick.

[0033] In this embodiment, transverse groove structures are provided at both upper and lower ends of the crossbeam profile 2, so that both upper and lower ends of the crossbeam profile 2 are connected to the column profile 1 through the connecting piece 3, thereby ensuring the installation stability of the crossbeam profile 2.

[0034] In this embodiment, a beam fastener 8 is fastened on the front of the beam profile 2, and the upper and lower ends of the beam fastener 8 extend downward to form a beam shielding portion 81 for shielding the end edges of the glass. When glass is provided on the top and bottom surfaces of the beam profile 2, the beam shielding portion 81 is used to shield the end edges of the upper and lower glasses, thereby improving the appearance of the glass after installation.

[0035] In this embodiment, the front face of the crossbeam profile 2 is provided with a recessed fastener groove 24 and crossbeam protrusions 25 at the upper and lower ends of the fastener groove 24. The back face of the crossbeam fastener 8 is provided with a raised crossbeam hook 82 that is fastened to the fastener groove 24 and two fastener protrusions 83 at the upper and lower ends of the crossbeam hook 82. When the crossbeam hook 82 is fastened to the fastener groove 24, each fastener protrusion 83 presses against a corresponding crossbeam protrusion 25. At the same time, the fastener protrusions 83 and the crossbeam protrusions 25 press against each other, causing the crossbeam hook 82 to press tightly against the fastener groove 24, thereby improving the installation quality of the crossbeam fastener 8. In addition, the front face of the crossbeam fastener 8 is provided with multiple fastener outer grooves 84, which can improve the strength and stability of the column profile 1 and ensure the stability of the derrick.

[0036] As a preferred embodiment, in order to improve the aesthetics of the derrick, the opening of the outer vertical groove 12 toward the crossbeam profile 2 is closed with a vertical decorative strip 100 to hide the first bolt 4 and the vertical portion 31 located in the outer vertical groove 12; similarly, the vertical opening of the outer transverse groove 22 is closed with a transverse decorative strip 200 to hide the second bolt 6 and the transverse portion 32 located in the outer transverse groove 22.

[0037] In this embodiment, the vertical decorative strip 100 and the horizontal decorative strip 200 are made of a third aluminum profile with the same structure. The vertical decorative strip 100 and the horizontal decorative strip 200 both include a horizontal decorative strip 1a and two integrally formed decorative buckles 2a arranged on the back of the horizontal decorative strip 1a, and the two decorative buckles 2a are symmetrically arranged; the outer vertical groove 12 and the outer horizontal groove 22 are both provided with a decorative groove 300 for accommodating the horizontal decorative strip 1a, and the two opposite groove walls of the outer vertical groove 12 and the two opposite groove walls of the outer horizontal groove 22 are both provided with decorative buckle grooves 400 that are buckled with the decorative buckle 2a. When the decorative buckle 2a is buckled in the decorative buckle groove 400, the back of the horizontal decorative strip 1a presses against the groove wall of the decorative groove 300, so that the horizontal decorative strip 1a closes the decorative groove 300, with a simple structure and easy installation.

[0038] In this embodiment, the vertical portion 31 is provided with a first through-hole for the screw rod of the first bolt 4 to pass through. The screw rod of the first bolt 4 is threadedly engaged with the first nut 5 after passing through the first through-hole. In addition, at least two first through-holes are provided along the vertical direction of the vertical portion 31, and each first through-hole is correspondingly engaged with a first bolt 4 and a first nut 5, thereby further improving the connection quality between the vertical portion 31 and the column profile 1. Similarly, the transverse portion 32 is provided with a second through-hole for the screw rod of the second bolt 6 to pass through. The screw rod of the second bolt 6 is threadedly engaged with the second nut 7 after passing through the second through-hole. In addition, at least two second through-holes are provided along the transverse direction of the transverse portion 32, and each second through-hole is correspondingly engaged with a second bolt 6 and a second nut 7, thereby further improving the connection quality between the transverse portion 32 and the crossbeam profile 2.

[0039] In this embodiment, the first nut 5 and the second nut 7 are both T-nuts. Therefore, by utilizing the characteristics of the T-nut, during installation, the first nut 5 can be directly inserted into the inner vertical groove 11 from the vertical insertion port, and then the first nut 5 can be rotated so that the first nut 5 can be stuck in the inner vertical groove 11, so that the first nut 5 can be placed in the inner vertical groove 11 at any position for easy installation; and the second nut 7 can be directly inserted into the inner transverse groove 21 from the transverse insertion port, and then the second nut 7 can be rotated so that the second nut 7 can be stuck in the inner transverse groove 21, so that the second nut 7 can be placed in the inner transverse groove 21 at any position for easy installation.
