Description

Technical Field

[0001] This utility model belongs to the field of elevator shaft technology, specifically relating to a prefabricated steel structure assembly shaft for elevator retrofitting. Background Technology

[0002] As people's living standards improve, the installation of elevators in existing low-rise buildings is becoming increasingly frequent. Currently, some older buildings and multi-story buildings that were not originally designed with elevator shafts are typically fitted with an outdoor elevator shaft if elevators are added later. Elevator shafts are generally made of steel structures.

[0003] The existing prefabricated steel structure elevator shaft is assembled by stacking multiple shaft sections, but it has the following defects: (1) When assembling the existing elevator shaft, each elevator shaft section is tightened by bolt assembly, which is time-consuming and laborious, resulting in low elevator shaft assembly efficiency. Therefore, we propose a prefabricated steel structure assembly shaft for elevator installation. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated elevator steel structure assembly shaft to solve the problem mentioned in the background art that the use of bolt assembly for tightening elevator shafts is time-consuming and labor-intensive, resulting in low assembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated elevator steel structure assembly shaft, comprising two shaft sections, each shaft section having an installation hole on its surface, a latch penetrating through the installation hole, a lock cap fitted on the outer wall of one end of the latch, an assembly groove on the side wall of one end of the latch, a locking block slidably connected inside the assembly groove, a top spring provided at one end of the locking block, and the other end of the locking block placed at the end of the lock cap.

[0006] Preferably, the side wall of the locking block is provided with a retaining groove, and a retaining block is provided inside the retaining groove. The retaining block is fixed on the inner wall of the assembly groove.

[0007] Preferably, the cross-section of the latch is T-shaped, and the longitudinal section of the latch is rectangular.

[0008] Preferably, the longitudinal section of the lock cap is a square-shaped structure, and the cross section of the lock cap is a rectangular structure.

[0009] Preferably, the end face of the latch is provided with a conical surface.

[0010] Preferably, a support rod is provided on the inner side of the top spring, and a support sleeve is sleeved on the outer wall of the support rod. The support sleeve is fixed on the surface of the assembly groove, and the support rod is fixed on the surface of the lock block.

[0011] Preferably, the longitudinal sections of both the handrail and the handrail tube are circular, and the central axes of the handrail and the handrail tube coincide with each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By designing the latch, the lock cap and the lock block, the mounting holes of adjacent shaft sections are aligned, and then the latch is inserted through the two adjacent mounting holes. The lock cap is then fitted onto the end of the latch, and the lock block blocks the end of the lock cap, thus achieving quick locking of this utility model. Compared with the bolt structure fixing method, the shaft installation efficiency is high and fast. The design of the stop block and the stop groove limits the lock block and prevents it from coming off the assembly groove. The design of the conical surface facilitates the latch to pass through the mounting hole. The design of the support rod and the support cylinder plays a straightening role and prevents the top spring from being compressed and losing elasticity. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a prefabricated elevator steel structure assembly shaft, comprising two shaft sections 1, each shaft section 1 having an installation hole 3 on its surface. A latch 2 passes through the interior of the installation hole 3, a latch cap 4 is fitted onto the outer wall of one end of the latch 2, and an assembly groove 6 is formed on the side wall of one end of the latch 2. A locking block 7 is slidably connected inside the assembly groove 6, and a top spring 10 is provided at one end of the locking block 7. Through the designed latch 2, latch cap 4, and locking block 7, the installation holes 3 of adjacent shaft sections 1 are aligned. Then, the latch 2 is inserted through two adjacent mounting holes 3, and the lock cap 4 is fitted onto the end of the latch 2. The locking block 7 blocks the end of the lock cap 4, realizing the quick locking of this utility model. Compared with the bolt structure fixing method, the shaft installation is more efficient and faster. The other end of the locking block 7 is placed at the end of the lock cap 4. The side wall of the locking block 7 is provided with a retaining groove 8. The retaining groove 8 is provided with a retaining block 12. Through the designed retaining block 12 and retaining groove 8, the locking block 7 is limited and prevented from falling out of the assembly groove 6. The retaining block 12 is fixed on the inner wall of the assembly groove 6.

[0022] In this embodiment, preferably, the cross-section of the latch 2 is a T-shaped structure, the longitudinal section of the latch 2 is a rectangular structure, the longitudinal section of the lock cap 4 is a square-shaped structure, the cross-section of the lock cap 4 is a rectangular structure, and the end face of the latch 2 is provided with a conical surface 5. The designed conical surface 5 facilitates the latch 2 to pass through the mounting hole 3.

[0023] In this embodiment, preferably, a support rod 9 is provided on the inner side of the top spring 10, and a support cylinder 11 is sleeved on the outer wall of the support rod 9. The support cylinder 11 is fixed on the surface of the assembly groove 6, and the support rod 9 is fixed on the surface of the locking block 7. The support rod 9 and the support cylinder 11 are designed to play a straightening role and prevent the top spring 10 from becoming skewed and losing its elasticity due to compression. The longitudinal section of the support rod 9 and the support cylinder 11 are both circular structures, and the central axes of the support rod 9 and the support cylinder 11 coincide with each other.

[0024] The working principle and usage process of this utility model are as follows: Align the mounting holes 3 of adjacent shaft sections 1, then insert the buckle 2 through the two adjacent mounting holes 3, and then put the locking cap 4 on the end of the buckle 2. During the insertion process, the inclined surface of the locking block 7 is squeezed and slides into the assembly groove 6 to avoid affecting the insertion of the buckle 2 into the mounting hole 3 and the locking cap 4 on the buckle 2. Under the action of the top spring 10, the locking block 7 is pushed out from the assembly groove 6, blocking the end of the locking cap 4, thereby achieving quick locking of this utility model. Compared with the bolt structure fixing method, the shaft installation efficiency is high and fast.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
