Description

Technical Field

[0001] The utility model belongs to the technical field of safety accessories for elevator shaft construction, and specifically relates to a temporary protection device for elevator shaft openings. Background Art

[0002] The existing housing construction commonly uses a frame structure. During the construction process, elevator shafts are often reserved for subsequent elevator installation. Since the elevator shafts have openings, there will be certain risks if protective measures are not installed during the construction process.

[0003] Some of the existing edge protection devices for elevator shaft openings use protective nets. When installing the protective nets, tools are needed to drill holes in the elevator shaft and install bolts, and then nuts are used to fix the protective nets at the elevator shaft openings. This method has certain defects. Drilling holes in the elevator shaft with tools will damage the structure of the elevator shaft. Summary of the Utility Model

[0004] The utility model provides a buckle structure that facilitates the assembly between multiple protective fences in order to solve the above technical problems.

[0005] To solve the above technical problems, a temporary protection device for elevator shaft openings provided by the utility model includes a protective fence body and a clamping component. The clamping component is located on one side of the protective fence body and is used to connect multiple protective fence bodies together. The clamping component includes two U-shaped clamping blocks installed on the outer wall of the protective fence body. A rotating rod is rotatably connected between the two U-shaped clamping blocks. A connecting block is connected to the outer wall of the rotating rod. An arc-shaped clamping block is installed on the outer wall of the connecting block. A fixing block is installed on the outer wall of the protective fence body. A support rod is connected to the inner wall of the fixing block. A T-shaped insertion rod is rotatably connected to the outer wall of the support rod. The T-shaped insertion rod is located between the arc-shaped clamping block and the U-shaped clamping block.

[0006] Further, two support blocks are installed at the bottom of the protective fence body. An installation block is installed at the bottom end of the support block. Two installation rods are installed at the bottom of the installation block. Universal wheels are connected to the bottom ends of the installation rods.

[0007] Further, a control button is connected to the inner wall of the arc-shaped clamping block. An electric telescopic rod electrically connected to the control button is installed at the bottom of the installation block. A support plate is connected to the telescopic end of the electric telescopic rod. A ground nail is installed at the bottom of the support plate.

[0008] Further, an installation plate is installed at the top of the connecting block. The installation plate is provided with an insertion hole. The connecting block and the installation plate are both located between the two U-shaped clamping blocks. A gap is left between the connecting block and the U-shaped clamping blocks.

[0009] Further, a limiting plate is installed between the two U-shaped clamping blocks. The arc-shaped clamping block is located above the limiting plate. The outer wall of the arc-shaped clamping block abuts against the top of the limiting plate. The outer wall of the T-shaped insertion rod abuts against the inner wall of the arc-shaped clamping block. The inner wall of the T-shaped insertion rod abuts against the outer wall of one of the U-shaped clamping blocks.

[0010] Further, two limiting rings are installed on the outer wall of the rotating rod. The two U-shaped clamping blocks are located between the two limiting rings. The outer wall of the limiting ring abuts against the outer wall of the U-shaped clamping block.

[0011] After adopting the above technical solution, the present utility model has the following beneficial effects compared with the prior art.

[0012] 1. In the present utility model, when the T-shaped insertion rod is rotated and touches the arc-shaped clamping block, the arc-shaped clamping block will move upward under the extrusion of the T-shaped insertion rod. After the T-shaped insertion rod enters the inside of the U-shaped clamping block, the contact with the arc-shaped clamping block is released. The arc-shaped clamping block moves downward to return to its original position and wraps the T-shaped insertion rod between the arc-shaped clamping block and the U-shaped clamping block. At this time, the two guardrail bodies are already connected together. Through the clamping assembly, construction workers can choose to connect multiple guardrail bodies according to the on-site situation. When it is necessary to separate multiple guardrail bodies, the arc-shaped clamping block is toggled to move upward, so that the limit of the arc-shaped clamping block on the T-shaped insertion rod can be released, and the T-shaped insertion rod can be easily removed from the inside of the U-shaped clamping block. This combination method has a wide range of applicability and is convenient to use.

[0013] 2. In the present utility model, the mounting block is fixed below the guardrail body through the support block, and the universal wheel is fixed below the mounting block through the mounting rod. The flexibility of the movement of the guardrail body is increased through the universal wheel, so that the guardrail body can be easily moved, and it is more convenient to adjust the moving direction of the guardrail body.

Specific implementation mode

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0020] During the actual use of an existing temporary protection device for elevator shaft openings, when facing different length usage requirements, multiple sets of guardrails often need to be set up for protection, which requires carrying a large number of guardrails. However, since the guardrails of the above device need to be connected and fixed through multiple components, this will cause the operator to spend more time and energy to ensure that each component is correctly connected together, thereby affecting the operation time. Therefore, the above problem can be solved by a buckle structure to make it more convenient to assemble multiple guardrails.

[0021] As Figures 1 to 4 shown, the present utility model provides a temporary protection device for elevator shaft openings.

[0022] Specifically, as Figures 1 - 3 shown, a temporary protection device for elevator shaft openings includes a guardrail body 1 and a clamping component 2. The clamping component 2 is located on one side of the guardrail body 1 and is used to connect multiple guardrail bodies 1 together. The clamping component 2 includes two U-shaped clamping blocks 201 installed on the outer wall of the guardrail body 1. A rotating rod 202 is rotatably connected between the two U-shaped clamping blocks 201. A connecting block 203 is connected to the outer wall of the rotating rod 202. An arc-shaped clamping block 205 is installed on the outer wall of the connecting block 203. A fixed block 206 is installed on the outer wall of the guardrail body 1. A support rod 207 is connected to the inner wall of the fixed block 206. A T-shaped insertion rod 204 is rotatably connected to the outer wall of the support rod 207. The T-shaped insertion rod 204 is located between the arc-shaped clamping block 205 and the U-shaped clamping block 201.

[0023] In the present utility model, when it is necessary to join multiple fence bodies 1 together, rotate the T-shaped insertion rod 204 so that one side of the T-shaped insertion rod 204 located inside the fixed block 206 rotates along the outer wall of the support rod 207. When the outer wall of the T-shaped insertion rod 204 abuts against the outer wall of the arc-shaped clamping block 205, the arc-shaped clamping block 205 will move upward under the extrusion of the T-shaped insertion rod 204. While the connecting block 203 moves together with the arc-shaped clamping block 205, it will drive the rotating rod 202 to rotate along the two U-shaped clamping blocks 201 until the T-shaped insertion rod 204 enters the inside of the U-shaped clamping block 201 and releases the abutment against the arc-shaped clamping block 205. At this time, the arc-shaped clamping block 205 moves downward to return to its original position;

[0024] The position of the T-shaped insertion rod 204 is wrapped between the arc-shaped clamping block 205 and the U-shaped clamping block 201 to prevent the T-shaped insertion rod 204 from easily slipping out of the U-shaped clamping block 201. After the inner wall of the T-shaped insertion rod 204 abuts against the outer wall of one of the U-shaped clamping blocks 201, the two fence bodies 1 are already connected together. Through the clamping assembly 2, users can connect multiple fence bodies 1 as needed. When it is necessary to separate multiple fence bodies 1, just push the arc-shaped clamping block 205 to move it upward, and the limit of the arc-shaped clamping block 205 on the T-shaped insertion rod 204 can be released, so that the T-shaped insertion rod 204 can be easily removed from the inside of the U-shaped clamping block 201.

[0025] As a specific embodiment of the present utility model, the present utility model provides a temporary protection device for the elevator shaft opening.

[0026] Specifically, as shown in Figure 1 and Figure 4 shown, two support blocks 3 are installed at the bottom of the fence body 1. An installation block 4 is installed at the bottom end of the support block 3. Two installation rods 5 are installed at the bottom of the installation block 4. The bottom end of the installation rod 5 is connected with a universal wheel 6.

[0027] In the present utility model, the installation block 4 is fixed below the fence body 1 through the support block 3, and the universal wheel 6 is fixed below the installation block 4 through the installation rod 5. The flexibility of the movement of the fence body 1 is increased through the universal wheel 6, so that the fence body 1 can be easily moved, and it is more convenient to adjust the moving direction of the fence body 1. At the same time, the universal wheel 6 can also play a buffering role, reducing the impact and damage of factors such as uneven ground on the fence body 1 and extending its service life.

[0028] As another specific embodiment of the present utility model, the present utility model provides a temporary protection device for the elevator shaft opening.

[0029] Specifically, as shown in Figure 2 and Figure 4Given that, a control button 11 is connected to the inner wall of the arc-shaped clamping block 205, an electric telescopic rod 7 electrically connected to the control button 11 is installed at the bottom of the installation block 4, a support plate 8 is connected to the telescopic end of the electric telescopic rod 7, and a ground nail 9 is installed at the bottom of the support plate 8.

[0030] In the present utility model, when the T-shaped insertion rod 204 enters between the arc-shaped clamping block 205 and the U-shaped clamping block 201, it represents that the two guardrail bodies 1 have been connected. At this time, the outer wall of the T-shaped insertion rod 204 will touch the control button 11. The control button 11 is used to control the start of the electric telescopic rod 7. When the T-shaped insertion rod 204 touches the control button 11, the electric telescopic rod 7 is controlled to move downward through the control button 11. The electric telescopic rod 7 will drive the support plate 8 and the ground nail 9 to quickly move towards the ground, so that the ground nail 9 is inserted into the ground. When the bottom of the support plate 8 touches the ground, the electric telescopic rod 7 stops operating. There is a corresponding control circuit in the control button 11, so that the downward movement distance of the electric telescopic rod 7 is just enough for the support plate 8 to touch the ground. By inserting the ground nail 9 into the ground, the position of the guardrail body 1 is fixed, so that the guardrail body 1 will not be easily displaced or moved.

[0031] As another specific embodiment of the present utility model, the present utility model provides a temporary protection device for the elevator shaft opening.

[0032] Specifically, as Figures 2 - 3 Given that, a mounting plate 13 is installed at the top of the connecting block 203. The mounting plate 13 is provided with a jack. Both the connecting block 203 and the mounting plate 13 are located between the two U-shaped clamping blocks 201, and there is a gap between the connecting block 203 and the U-shaped clamping block 201.

[0033] In the present utility model, the mounting plate 13 increases the contact area of the arc-shaped clamping block 205. When the user needs to move the position of the arc-shaped clamping block 205, the user can insert a finger into the jack provided in the mounting plate 13, and then pull the mounting plate 13 to drive the connecting block 203 and the arc-shaped clamping block 205 to move. There is a gap between the connecting block 203 and the U-shaped clamping block 201, so that the connecting block 203 will not generate friction with the U-shaped clamping block 201 when rotating, reducing the wear between the connecting block 203 and the U-shaped clamping block 201.

[0034] As another specific embodiment of the present utility model, the present utility model provides a temporary protection device for the elevator shaft opening.

[0035] Specifically, as Figure 3It is shown that a limit plate 10 is installed between the two U-shaped clamping blocks 201, the arc-shaped clamping block 205 is located above the limit plate 10, the outer wall of the arc-shaped clamping block 205 is against the top of the limit plate 10, the outer wall of the T-shaped insertion rod 204 is against the inner wall of the arc-shaped clamping block 205, and the inner wall of the T-shaped insertion rod 204 is against the outer wall of one of the U-shaped clamping blocks 201.

[0036] In the present invention, when the T-shaped rod 204 is located between the arc block 205 and the U-shaped clamping block 201, the inner top wall of the arc block 205 will abut against the outer wall of the T-shaped rod 204, so that the arc block 205 will not rotate to the bottom of the U-shaped clamping block 201. However, when the T-shaped rod 204 is not inside the U-shaped clamping block 201, the arc block 205 lacks the abutment of the T-shaped rod 204 and will move downward from the gap between the two U-shaped clamping blocks 201. When entering between the U-shaped clamping blocks 201 for the first time, it is necessary to push the arc-shaped clamping block 205 upward to move the T-shaped insertion rod 204 into the U-shaped clamping block 201. Therefore, the gap between the two U-shaped clamping blocks 201 is blocked by the limiting plate 10, so that the arc-shaped clamping block 205 will not fall below the U-shaped clamping block 201, and the inner wall of the T-shaped insertion rod 204 is against the outer wall of one of the U-shaped clamping blocks 201, so that the T-shaped insertion rod 204 will not be easily pulled out from one side of the U-shaped clamping block 201.

[0037] As another specific implementation of the utility model, the utility model provides a temporary protective device for an elevator shaft opening.

[0038] Specifically, Figure 3 It is shown that two limiting rings 12 are installed on the outer wall of the rotating rod 202 , and the two U-shaped clamping blocks 201 are located between the two limiting rings 12 , and the outer wall of the limiting ring 12 abuts against the outer wall of the U-shaped clamping block 201 .

[0039] In the present invention, because the rotating rod 202 will frequently rotate along the U-shaped clamping block 201, the rotating rod 202 is stabilized between the two U-shaped clamping blocks 201 by the limiting ring 12. The function of the limiting ring 12 is to limit the position of the rotating rod 202 to prevent the rotating rod 202 from slipping out of the U-shaped clamping block 201 when rotating. The limiting ring 12 makes the connection between the rotating rod 202 and the U-shaped clamping block 201 more stable.

[0040] Working principle: When multiple guardrail bodies 1 need to be spliced together, the T-shaped rod 204 is rotated so that the side of the T-shaped rod 204 located inside the fixed block 206 rotates along the outer wall of the support rod 207. When the outer wall of the T-shaped rod 204 contacts the outer wall of the arc block 205, the arc block 205 is squeezed by the T-shaped rod 204 and moves upward. The connecting block 203 moves with the arc block 205 and drives the rotating rod 202 to rotate along the two U-shaped clamping blocks 201 until the T-shaped rod 204 enters the U-shaped clamping block 201 and releases the contact with the arc block 205. At this time, the arc block 205 moves downward and returns to its original position.

[0041] The T-shaped rod 204 is wrapped between the arc-shaped clamping block 205 and the U-shaped clamping block 201 to prevent the T-shaped rod 204 from easily slipping out of the U-shaped clamping block 201. When the inner wall of the T-shaped rod 204 is against the outer wall of one of the U-shaped clamping blocks 201, the two guardrail bodies 1 are connected together. The clamping assembly 2 allows the user to connect multiple guardrail bodies 1 as needed. When it is necessary to separate multiple guardrail bodies 1, it is only necessary to move the arc-shaped clamping block 205 upward to release the limit of the arc-shaped clamping block 205 on the T-shaped rod 204, so that the T-shaped rod 204 can be easily moved out from the inside of the U-shaped clamping block 201.

[0042] The mounting block 4 is fixed to the bottom of the guardrail body 1 through the support block 3, and the mounting rod 5 fixes the universal wheel 6 to the bottom of the mounting block 4. The universal wheel 6 increases the flexibility of the movement of the guardrail body 1, so that the guardrail body 1 can be easily moved, and it is more convenient to adjust the moving direction of the guardrail body 1. At the same time, the universal wheel 6 can also play a buffering role, reducing the impact and damage of the guardrail body 1 caused by factors such as uneven ground, thereby extending its service life.

[0043] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
