In the figure: 1 is a protective plate; 2 is a shaft hole plate; 3 is a rotating shaft; 4 is an inner clamping rod; 5 is a sleeve; 6 is an outer clamping rod; 7 is a fastener; 8 is an unlocking handle; 9 is a wall body.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, the protective structure for the elevator door opening comprises a protective plate 1 arranged in the elevator door opening, wherein a shaft hole is formed in the protective plate 1, and a rotating shaft 3 is rotatably arranged in the shaft hole; the inner end of the rotating shaft 3 penetrates through the shaft hole and is fixedly provided with an inner clamping rod 4, the outer end of the rotating shaft 3 penetrates through the shaft hole and is connected with a sleeve 5, and the sleeve 5 can synchronously rotate along with the rotating shaft 3 and can axially slide along the rotating shaft 3; an outer clamping rod 6 is fixed on the sleeve 5, and the inner clamping rod 4 and the outer clamping rod 6 are parallel to each other; a threaded section is arranged at the outer end of the rotating shaft 3 and positioned on the outer side of the sleeve 5, a fastener 7 is connected to the threaded section in a threaded manner, and the fastener 7 pushes the outer clamping rod 6 on the sleeve 5 to be close to the inner clamping rod 4 when rotating on the threaded section of the rotating shaft 3, so that the inner clamping rod 4 and the outer clamping rod 6 are horizontally clamped on the inner wall and the outer wall of the wall 9 on two sides of the elevator door opening, and the protective grating is fixed on the wall 9 on two sides of the elevator door opening; an unlocking handle 8 is arranged at the outer end of the rotating shaft 3 and positioned outside the fastener 7, and when the unlocking handle 8 is rotated, the rotating shaft 3 and the inner clamping rod and the outer clamping rod on the rotating shaft can be driven to rotate for a certain angle, so that the inner clamping rod and the outer clamping rod are separated from clamping walls 9 on two sides of the elevator door opening.

The elevator door opening protection structure of the utility model has the advantages that the inner clamping rod 4 and the sleeve 5 are coaxially connected, so that the inner clamping rod 4 and the outer clamping rod 6 can synchronously rotate along with the rotating shaft 3, when the rotating shaft 3 rotates, the inner clamping rod 4 and the outer clamping rod 6 are positioned at two sides of the wall body 9, and the protection plate 1 can be fixed between the wall body 9; and through setting up fastener 7, fastener 7 rotates along the axial on axis of rotation 3 and can make interior clamping bar 4 and outer clamping bar 6 further draw close each other, makes and fixes more firmly between interior clamping bar 4, outer clamping bar 6 and the wall body 9.

The sleeve 5 rotates synchronously with the rotating shaft 3 and is axially movable by the movement of the fastening member 7, so that the sleeve 5 is splined to the rotating shaft 3.

The length of interior clamping bar 4 and outer clamping bar 6 is greater than elevator door opening width and can satisfies this technical scheme, but too long also can increase the use degree of difficulty, so the length of interior clamping bar 4 and outer clamping bar 6 is unanimous, and the length of interior clamping bar 4 and outer clamping bar 6 is the length of elevator door opening diagonal.

The inner clamping rods 4 and the outer clamping rods 6 are two parallel, and the two inner clamping rods 4 are located between the two outer clamping rods 6. The design of two parallel rods is selected, and firstly, the protection structure has better rigidity than a single rod, so that the protection structure is firmer; second, the design that the double pole is parallel from top to bottom can further make including guard plate upper portion and lower part clamping bar 4 and outer clamping bar 6 clamping process make guard plate 1 upper and lower portion atress more single pole even, make clamping process or fixed completion back guard plate 1 more stable.

The unlocking handles 8 are two parallel and fixed on the rotating shaft 3, and a slot for inserting the force arm lever is formed between the two unlocking handles 8. When in the construction process, if the simple use is twisted to unblock handle 8 and is moved and make this elevator door opening protective structure fixed stable probably have the difficulty, then can use instruments such as reinforcing bar or wooden stick to put into above-mentioned slot that supplies arm of force lever male, increase the application of force arm of force, can be more relaxed to the turning shaft 3 application turning force.

The guard plate 1 is a guard grating, an axial hole plate 2 is arranged at the guard grating close to the upper center, and the axial hole plate 2 is arranged at the center of the axial hole plate. The use of the protective grating can reduce the use of materials, and the condition in the elevator door opening can be observed through the protective grating; lean on at the protective grating and be provided with axle hole board 2 in the middle position, can be so that satisfy general people's height, make axis of rotation 3 be in not low or the position of overheight, the manual work of being convenient for drives.

The fastening member 7 includes a nut and a fastening handle vertically connected to a side surface of the nut, and the nut can be rotated more easily by rotating the fastening handle.

Finally, it is noted that the above-mentioned embodiments illustrate rather than limit the invention, and that, while the invention has been described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
