Description

Technical Field

[0001] This utility model relates to the field of elevator sheet metal parts technology, specifically to a detachable modular elevator sheet metal door frame assembly. Background Technology

[0002] Elevator sheet metal door frames are the metal frame structures of elevator door openings, made of stainless steel or galvanized steel sheets. They include the top lintel, side columns, and bottom sill, and mainly serve to support the door's operation, provide decoration and aesthetics, and ensure safety. The surface is treated with processes such as wire drawing and spraying, combining durability and aesthetics, and is widely compatible with different elevator models and architectural styles.

[0003] Existing elevator sheet metal door frames are typically one-piece structures, and these frames need to be custom-made according to the specific dimensions of the elevator shaft door opening. If there are errors in the dimensions of the door opening at the construction site or if the width needs to be adjusted during later renovations, new molds or reprocessing are required, resulting in long cycles, high costs, and an inability to flexibly meet the needs of different scenarios. In addition, the entire door frame needs to be hoisted during installation, which places high demands on transportation and on-site operation space. Especially in narrow shafts, it is prone to deformation due to bumps, and after deformation, the entire structure needs to be dismantled and replaced, resulting in high maintenance costs and affecting elevator downtime. To address these issues, a detachable modular elevator sheet metal door frame component is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows:

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A detachable modular elevator sheet metal door frame assembly includes a lintel, and side door frames are provided on both sides of the lintel;

[0007] The lintel includes a crossbeam assembly, and two crossbeam assemblies are provided. An inner storage groove is provided on one side of the bottom surface of the two crossbeam assemblies, and an outer storage groove is provided on the other side of the bottom surface of the crossbeam assemblies. The interior of the inner storage groove is connected to the interior of the outer storage groove.

[0008] The top surfaces of the two beam assemblies are fixedly connected with slide rails, and the slide rails are aligned with the short side of the top surface of the beam assembly in the length direction. The inner walls of each slide rail are slidably connected with convex sliders, and the upper end of the outer wall of each convex slider is threaded with a nut.

[0009] Among them, a rotating shaft is fixedly connected to the top of the crossbeam assembly on one side. A connecting rod 1 is rotatably connected to the lower end of the outer wall of the rotating shaft, and a connecting rod 2 is rotatably connected to the upper end of the outer wall of the rotating shaft. A nut 2 is threadedly connected to the upper end of the rotating shaft. The bottom surface of the nut 2 abuts against the middle of the connecting rod 2. Both ends of the connecting rod 1 and the connecting rod 2 are rotatably connected to the upper end of the convex slider. The bottom surface of each nut 1 abuts against the top surface of the connecting rod 1 and the connecting rod 2, respectively.

[0010] As a further embodiment of this utility model: a positioning hole is symmetrically provided at the lower end of the side of one side of the crossbeam assembly, and a positioning rod is symmetrically fixedly connected at the lower end of the side of the other side of the crossbeam assembly. The inner wall of the positioning hole is inserted into the positioning rod, and the side walls of the two crossbeam assemblies abut against each other.

[0011] As a further embodiment of this utility model: the lintel also includes a gap-covering plate, and both ends of the top surface of the gap-covering plate are threaded with a bolt. The middle of the bolt is connected through to the top surface of each crossbeam assembly, and the bottom surface of the bolt abuts against the top surface of the crossbeam assembly.

[0012] As a further embodiment of this utility model: the two sides of the seam cover are slidably connected to the inner side of each inner storage groove, and the overall width of the seam cover is consistent with the inner width of the inner storage groove.

[0013] As a further embodiment of this utility model: the side door frame includes two columns, and an mounting plate is fixedly connected to the upper end of the outer wall of each column.

[0015] As a further embodiment of this utility model: the overall width of the mounting plate is consistent with the width of the inner wall of the outer storage groove, and the middle part of the second bolt is threadedly connected to the inner wall of the crossbeam assembly.

[0016] The beneficial effects of this utility model are:

[0017] In this utility model, the elevator door frame is composed of the lintel and the side door frame. When the elevator door frame and the lintel need to be transported, they can be transported separately, which facilitates transportation in narrow elevator shafts and reduces the probability of door frame components being bumped. If there is partial damage, only the corresponding module needs to be replaced, without dismantling the entire frame, which greatly shortens the maintenance time and reduces labor costs.

[0018] The lintel in the elevator door frame adopts a telescopic and splicing structure design, which can be freely adjusted within a certain range. The overall lintel and the side door frame spacing width are compatible with different door opening sizes, reducing the need for customized production and reducing inventory pressure.

The slide rail 102 and the short side of the top surface of the crossbeam assemblies 101 are aligned in the length direction. The inner wall of each slide rail 102 is slidably connected to a protrusion. The slider 103 has a nut 104 threadedly connected to the upper end of its outer wall. A rotating shaft 109 is fixedly connected to the top of a single-sided crossbeam assembly 101. A connecting rod 110 is rotatably connected to the lower end of the outer wall of the rotating shaft 109, and a connecting rod 111 is rotatably connected to the upper end of the outer wall of the rotating shaft 109. A nut 112 is threadedly connected to the upper end of the rotating shaft 109. The bottom surface of the nut 112 abuts against the middle of the connecting rod 111. Both ends of the connecting rods 110 and 111 are rotatably connected to the upper end of the slider 103. The bottom surfaces of each nut 104 abut against the top surfaces of the connecting rods 110 and 111, respectively. Figure 5 As shown, threads are provided on the upper end of the outer wall of both the convex slider 103 and the rotating shaft 109 to facilitate the installation of each nut;

[0028] A positioning hole 107 is symmetrically provided on the lower side of one side of the crossbeam assembly 101, and a positioning rod 108 is symmetrically fixedly connected to the lower side of the other side of the crossbeam assembly 101. The inner wall of the positioning hole 107 is inserted into the positioning rod 108, and the side walls of the two crossbeam assemblies 101 abut against each other. Figure 4 As shown, the positioning rod 108 is inserted into the positioning hole 107, which facilitates the alignment of the crossbeam assembly 101;

[0029] The lintel 1 also includes a seam cover 113. Bolts 114 are threaded to both ends of the top surface of the seam cover 113. The middle of each bolt 114 is connected through to the top surface of the crossbeam assembly 101, and the bottom surface of the bolt 114 abuts against the top surface of the crossbeam assembly 101. The two sides of the seam cover 113 are slidably connected to the inner sides of each inner storage groove 105, and the overall width of the seam cover 113 is consistent with the internal width of the inner storage groove 105.

When it is necessary to fix it, nut 104 is installed on the convex slider 103 and screwed on, and nut 212 is installed on the rotating shaft 109 and screwed on. Then, by fixing the included angle between connecting rod 110 and connecting rod 211, the positioning between the crossbeam assemblies 101 is achieved.

[0033] Next, push the gap-covering plate 113 so that it is inserted into the inner storage grooves 105 on both sides. The gap-covering plate 113 can cover the gap between the beam assemblies 101 and improve the aesthetics of the door frame. Then, tighten the bolt 114 to the top of the gap-covering plate 113 from above the beam assembly 101 to fix the gap-covering plate 113 to the beam assembly 101. Finally, install the uprights 201 on both sides of the lintel 1. Insert the mounting plate 202 below into the outer storage groove 106 and screw the bolt 203 into the surface of the mounting plate 202 above to fix it.
