DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] This embodiment provides a lead plate protective door body, referring to Figure 1-2 The door body 1 is the same as the existing structure, and is provided with an observation window 7 and a door handle 8. The specific structure of the door body 1 can be conventionally adopted in the art. For example, the door body 1 includes an outer panel 101 and an inner panel 102. A main protective lead plate 103 is provided on the inner side of the inner panel 102. The door body 1 has a plurality of frames inside, and the frames are arranged between the outer panel 101 and the inner panel 102. For the convenience of description, the three frames from bottom to top at the lower end of the door body 1 are named lower frame 104, middle frame 105 and upper frame 106 respectively.

[0022] refer to Figure 3 A first gap is left between the lower end of the door body 1 and the ground 11, namely H1 as shown in the figure. A lifting protection assembly 2 is provided at the lower end of the door body 1. The lifting protection assembly 2 includes a protection plate 201, a connecting seat 202 and a driving element 203. In this embodiment, the protection plate 201 includes two parallel mounting plates 2011 and an auxiliary protection lead plate 2012. The mounting plate 2011 is fixedly connected to the connecting seat 202 (for example, welded). The auxiliary protection lead plate 2012 is clamped between the two mounting plates 2011 by a number of clamping screws 204. It should be understood that in other embodiments, the protection plate 201 may also be other structures as long as it can shield radiation.

[0023] The upper end of the driving element 203 is connected to the frame. It should be understood that the nearest frame is selected for installation. In this embodiment, the upper end of the driving element 203 is connected to the middle frame 105, and the lower end of the driving element 203 is connected to the connecting seat 202. In this embodiment, the driving element 203 selects an electric push rod. Other embodiments can also select a cylinder, a hydraulic cylinder, etc. During installation, the output end of the electric push rod is the lower end, and the other end is the upper end. Further, the lower end of the driving element 203 is hinged to the connecting seat 202. Specifically, the connecting seat 202 is a U-shaped structure. The output end of the electric push rod can be provided with a connecting block, and the connecting block is connected to the connecting seat 202 by bolts and nuts.

[0024] The door body 1 is provided with a slide groove for the protective plate 201 to slide. Specifically, the slide groove is arranged on the lower frame 104. When the driving element 203 is working, it is used to drive the protective plate 201 to rise or fall, thereby closing or exposing the first gap. It can be seen that in the utility model, a lifting protection component 2 is added inside the door body 1. After the door is closed, the protective plate 201 can be lowered by the driving element 203, thereby closing the first gap between the door body 1 and the ground 11 to prevent radiation from leaking from the first gap; at the same time, before the door is opened, the protective plate 201 can be raised by the driving element 203 to avoid affecting the opening and movement of the door. In addition, it should be understood that, generally speaking, the protective door has a certain width, and the auxiliary protective lead plate 2012 in the protective plate 201 has a certain weight. Therefore, in practical applications, at least two driving elements 203 can be used to drive the lifting and lowering of the protective plate 201.

[0025] It is worth noting that, if the protective plate 201 has already abutted against the ground 11 before the output end of the driving element 203 moves to the extreme position, then if the output end of the driving element 203 continues to move at this time, it is easy to cause damage to the driving element 203. For this reason, the present embodiment is further optimized on the basis of the above. Specifically, the upper end of the driving element 203 is connected (for example, by screws) with a connecting plate 3, and a connecting shaft 4 is provided on the top of the connecting plate 3, which can be welded to the connecting plate 3 as a whole. The connecting shaft 4 can slide up and down and pass through the middle frame 105, and the upper end of the connecting shaft 4 is connected to the limiting member 5. When the protective plate 201 is raised, there is a second gap between the connecting plate 3 and the middle frame 105, that is, H2 as shown in the figure. With such a configuration, if the protective plate 201 has already abutted against the ground 11 before the output end of the driving element 203 moves to the extreme position, the shell part of the driving element 203 can also move upward, which well avoids the above problem.

[0026] It is easy to understand that the function of the above-mentioned limit member 5 is to prevent the connecting shaft 4 and the middle frame 105 from falling off. In this embodiment, the limit member 5 is a nut. It should be understood that the limit member 5 of other embodiments may of course also be in other forms, as long as it can prevent the connecting shaft 4 and the middle frame 105 from falling off. For example, the limit member 5 is a screw radially connected to the connecting shaft 4.

[0027] On the basis of the above, a plug 6 is provided on the top of the connecting plate 3, and a socket that cooperates with the plug 6 is provided on the frame. In this arrangement, it should be understood that the socket has a sufficient depth to prevent the plug 6 from being separated from the socket. It is worth noting that the arrangement of the socket and the plug 6 can prevent the electric push rod from rotating after installation.

[0028] Embodiment 2

[0029] refer to Figure 1The present embodiment provides a protective door, including the door body 1 provided in the first embodiment, and also including a hanger 9, a guide rail 10 and a driving assembly (not shown in the figure). The guide rail 10 is fixed on the wall above the door body 1, and the driving assembly is fixed on the guide rail 10. The door body 1 is fixedly connected to the hanger 9, and the hanger 9 is connected to the driving assembly. The driving assembly can drive the door body 1 to move along the guide rail 10. The specific form of the driving assembly is not limited, and the conventional method in the field can be adopted. For example, the driving assembly includes a transmission belt conveyor, and the hanger 9 is connected to a certain point on the straight section of the belt through a connecting member. When the belt rotates in a ring, the hanger 9 follows the movement.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
