Description

Technical Field

[0001] This utility model relates to the field of elevator shaft protection, and in particular to an elevator shaft protection device. Background Technology

[0002] During building construction, protective devices are required to be installed at the elevator door positions before elevator installation inside the elevator shaft. These protective devices are generally made of baffles, which are nailed to the walls on both sides. This method of protection has several drawbacks: first, it damages the wall surface by drilling holes for fixing; second, it is very inconvenient to install and remove the protective devices; and third, this method is generally fixed and cannot be adjusted in length. For elevator doors of different widths, only longer protective devices can be used for uniform fixing, and sometimes the protective devices protrude from one side of the wall. Therefore, an elevator shaft protective device is proposed to address the above problems. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide an elevator shaft protection device, which has a sliding adjustable plate inside the protective plate. When constructing elevator doors of different widths, the protective plates on both sides are slid, and the adjustable plate is exposed, allowing for adjustment according to the actual situation and expanding the scope of application.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an elevator shaft protection device, comprising two sets of protective plates, an adjustable plate installed in the central part of the protective plates, and a clamping mechanism installed on one side of each set of protective plates; A third fixing screw is installed above the protective plate on one side.

[0005] During building construction, protective devices are required at the elevator door positions before elevator installation inside the elevator shaft. These devices typically consist of baffles nailed to the walls on both sides. This method has several drawbacks: firstly, it damages the wall surface by drilling holes for fixing; secondly, it is inconvenient to install and remove the protective devices; and thirdly, this fixed method cannot be adjusted in length, requiring the use of longer protective devices for elevator doors of different widths, sometimes resulting in the protective device protruding from one side of the wall. By installing two sets of protective plates with adjustable sliding plates inside, the adjustable plates can be revealed when installing elevator doors of different widths, allowing for adjustments based on the actual situation and expanding the usability.

[0006] Furthermore, the clamping mechanism includes an L-shaped clamping plate, a sliding rod is slidably connected to one side of the clamping plate, the other end of the sliding rod is fixedly connected to the protective plate, and a second fixing screw is provided above the sliding rod and is spirally connected to the clamping plate. The second fixing screw passes through the front and rear end faces of the protective plate. The clamping plates are all fixedly connected with cushioning pads, which are made of rubber.

[0007] Furthermore, the number of clamping plates is four sets.

[0008] During the fixing process, the clamping plate is clipped onto the outside of the wall of the elevator doors on both sides. The clamping plate can be moved and clamped to the wall by fixing it with the second fixing screw. The sliding rod serves as a guide to ensure the stable movement of the clamping plate, while the buffer pad can ensure a tight fit with the wall.

[0009] Furthermore, the adjustable plate includes an extension plate that is fixedly connected to the protective plate on one side, and a sliding connection between the other side of the extension plate and the protective plate. The surface of the extension plate has multiple sets of evenly distributed waist-shaped grooves, and each waist-shaped groove is provided with a sliding shaft. A downward sliding plate is fixedly connected to one side of the sliding shaft.

[0010] Furthermore, the top two sides of the extension plate are respectively provided with a first fixing hole and a second fixing hole, and the second fixing hole is arranged in multiple groups.

[0011] Furthermore, the surface of the lower plate is provided with threaded holes, and each threaded hole is provided with a first fixing screw, which passes through one side of the extension plate.

[0012] Furthermore, the lower side of the sliding plate is set at an angle.

[0013] When the adjustable plate is used for protection, the lower plate at the corresponding position at the bottom of the extension plate slides down and is fixed by the first fixing screw. At this time, it can be stably attached to the ground to prevent debris from falling. When storing the extension plate, it can be smoothly moved upward by sliding the protective plate on one side and the inclined surface of the lower plate, making it easy to store.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up two sets of protective plates and installing adjustable sliding plates inside the protective plates, when constructing elevator doors of different widths, the adjustable plates can be exposed by sliding the protective plates on both sides, allowing for adjustments to be made according to the actual situation and expanding the scope of use. Furthermore, when the adjustable plate is used for protection, the lower plate at the corresponding position at the bottom of the extension plate slides down and is fixed by the first fixing screw. At this time, it can be stably attached to the ground to prevent debris from falling. When storing the extension plate, it can be smoothly moved upward by sliding the protective plate on one side and under the action of the inclined surface of the lower plate, making it easy to store. During the fixing process, the clamping plate is clipped onto the outside of the wall of the elevator doors on both sides. The clamping plate can be moved and clamped to the wall by fixing it with the second fixing screw. The sliding rod serves as a guide to ensure the stable movement of the clamping plate, while the buffer pad can ensure a tight fit with the wall. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example

[0018] An elevator shaft protection device, such as Figure 1-3 As shown, it includes two sets of protective plates 1, an adjustable plate 2 is installed in the center of the protective plate 1, and a clamping mechanism 3 is installed on one side of each set of protective plates 1. A third fixing screw 4 is installed above the protective plate 1 on one side.

[0019] During building construction, protective devices are required at the elevator door positions before elevator installation inside the elevator shaft. These devices typically consist of baffles, nailed to the walls on both sides. This method has several drawbacks: firstly, it damages the walls by drilling holes for fixing; secondly, it is inconvenient to install and remove the protective devices; and thirdly, it is generally fixed and cannot be adjusted in length. For elevator doors of different widths, only longer protective devices can be used for uniform fixing, sometimes resulting in the protective device protruding from one side of the wall. By installing two sets of protective plates 1, and incorporating adjustable sliding plates 2 inside the protective plates 1, the adjustable plates 2 can be revealed by sliding the protective plates 1 on both sides during construction of elevator doors of different widths. This allows for adjustments based on the actual situation, expanding the usability of the protective devices.

[0020] Each clamping mechanism 3 includes an L-shaped clamping plate 301. A sliding rod 302 is slidably connected inside one side of the clamping plate 301. The other end of the sliding rod 302 is fixedly connected to the protective plate 1. A second fixing screw 303 is provided above the sliding rod 302 and is spirally connected to the clamping plate 301. The second fixing screw 303 passes through the front and rear end faces of the protective plate 1. The clamping plate 301 is fixedly connected to a buffer pad 304, which is made of rubber.

[0021] There are four sets of clamping plates 301.

[0022] When fixing, the clamping plate 301 is clamped on the outside of the wall of the elevator doors on both sides. By fixing it with the second fixing screw 303, the clamping plate 301 can be moved and clamped to the wall. The sliding rod 302 serves as a guide to ensure that the clamping plate 301 moves stably, while the buffer pad 304 can fit tightly to the wall.

[0023] The adjustable plate 2 includes an extension plate 201 fixedly connected to the protective plate 1 on one side, and a sliding connection between the other side of the extension plate 201 and the protective plate 1. The surface of the extension plate 201 is provided with multiple sets of evenly distributed waist-shaped grooves 202, and each waist-shaped groove 202 is provided with a sliding shaft 203. A downward moving plate 204 is fixedly connected to one side of the sliding shaft 203.

[0024] The top two sides of the extension plate 201 are respectively provided with a first fixing hole 206 and a second fixing hole 207, and the second fixing hole 207 is arranged in multiple groups.

[0025] The surface of the lower plate 204 is provided with threaded holes, and each threaded hole is provided with a first fixing screw 205, which passes through one side of the extension plate 201.

[0026] The lower side of the lower plate 204 is inclined.

[0027] When the adjustable plate 2 is used for protection, the lower plate 204 at the corresponding position at the bottom of the extension plate 201 automatically slides down and is fixed by the first fixing screw 205. At this time, it can be stably attached to the ground to prevent debris from falling. When storing the extension plate 201, it can be smoothly moved up by the protective plate 1 on the sliding side under the action of the inclined surface of the lower plate 204, which makes it easy to store. The first fixing hole 206, in conjunction with the third fixing screw 4, can be used to store the adjustable plate 2, while the second fixing hole 207, in conjunction with the third fixing screw 4, can be used to adjust the length of the adjustable plate 2. Adjustments can be made according to actual conditions to expand the range of applications. The first fixing screw 205 passes through the extension plate 201 and connects to the lower moving plate 204. At this time, it can be used to fix the lower moving plate 204 and ensure that the lower moving plate 204 is stable and plays a blocking role.

[0028] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
