DETAILED DESCRIPTION
[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0020] like Figure 1-Figure 5 As shown, the present embodiment provides a medical radiation proof door bottom seam shielding device, comprising a bracket 1, a moving rod 3, a first clamping piece 4 and a second clamping piece 6. Isolation grooves 2 are connected to both sides of the bracket 1. Both ends of the moving rod 3 are respectively inserted into corresponding isolation grooves 2. The moving rod 3 slides in the isolation groove 2 along the vertical direction. The first clamping piece 4 is fixedly connected to one side of the moving rod 3. A first inclined surface 5 is provided on one side of the first clamping piece 4. A second inclined surface 7 is provided on one side of the second clamping piece 6. The first inclined surface 5 cooperates with the second inclined surface 7. The second clamping piece 6 and the first clamping piece 4 are clamped together to form a sealing structure.
[0021] The utility model fixes the bracket 1 at the lower side of the door frame, and the second clamping piece 6 is fixed at the lower side of the radiation protection door. When the radiation door is closed, the second inclined surface 7 on the second clamping piece 6 contacts the first inclined surface 5 on the first clamping piece 4, and the second clamping piece 6 pushes the first clamping piece 4 to make the moving rod 3 slide on the upper side of the bracket 1. Then the first clamping piece 4 and the second clamping piece 6 are clamped with each other to form a stable sealing structure. Not only can a stable sealing structure be formed to perform radiation protection operation on the door gap, but it can also be used for a long time without significant wear and tear.
[0022] Specifically, it also includes two guide rods 8 and two springs 9. The two guide rods 8 correspond one-to-one to the isolation grooves 2. The guide rods 8 are connected to the isolation grooves 2. The two guide rods 8 respectively pass through the two sides of the moving rod 3. The guide rods 8 are slidingly connected to the moving rod 3. The two springs 9 correspond one-to-one to the guide rods 8. The springs 9 are sleeved on the guide rods 8, and the springs 9 are on the upper side of the moving rod 3.
[0023] In the above embodiment, the moving rod 3 slides on the upper side of the bracket 1 by means of the guide rod 8. When the first clamping member 4 and the second clamping member 6 are clamped with each other, the spring 9 provides elastic force for the moving rod 3, so that the moving rod 3 has a downward movement tendency, thereby making the clamping of the first clamping member 4 and the second clamping member 6 more stable and reliable, further improving its protection effect.
[0024] Specifically, it also includes:
[0025] The sealing member 10 has one side fixedly connected to the bracket 1 and the other side fixedly connected to the moving rod 3; the sealing member 10 is a wave-shaped foldable cushion.
[0026] In the above embodiments, the wave-shaped foldable sealing member 10 is a soft cushion, which not only does not affect the up and down sliding operation of the moving rod 3, but also can seal the space between the moving rod 3 and the bracket 1, further improving the protective effect of the device.
[0027] Specifically, it also includes a bidirectional screw rod 11, a motor 12, two sliders 13, two telescopic push rods 14 and a front cover 15. The bidirectional screw rod 11 is rotatably connected to one side of the bracket 1, the motor 12 is connected to one side of the bracket 1, the output shaft of the motor 12 is fixedly connected to the bidirectional screw rod 11, the two sliders 13 are respectively screwed on both sides of the bidirectional screw rod 11, the two telescopic push rods 14 correspond to the sliders 13 one by one, the first end of the telescopic push rod 14 is hinged to the slider 13, the second end of the telescopic push rod 14 is hinged to the moving rod 3, and the front cover 15 is connected to one side of the bracket 1.
[0028] In the above embodiment, when the door needs to be opened, the motor 12 runs to drive the bidirectional screw rod 11 to rotate. The rotation of the bidirectional screw rod 11 causes the sliders 13 on both sides to move, thereby driving the telescopic push rod 14, so that the two telescopic push rods 14 make a connecting rod movement, and the two telescopic push rods 14 push the moving rod 3 to move upward, thereby separating the first clamping member 4 and the second clamping member 6 from each other, thereby facilitating the opening of the radiation-proof door. The front cover 15 is used to protect the motor 12, the bidirectional screw rod 11 and other components.
[0029] Specifically, it also includes a first embedded component 16 and two second embedded components 17 . The first embedded component 16 is connected to the lower side of the bracket 1 , and the two second embedded components 17 are respectively connected to the two ends of the bracket 1 .
[0030] In the above embodiments, the first embedded member 16 is used to be embedded in the bottom surface, and the second embedded member 17 is used to be embedded in the walls on both sides, which not only increases the stability of the bracket 1 and the overall device, but also prevents gaps under the door, further improving its radiation protection effect.
[0031] The working principle of the utility model is as follows: first, the bracket 1 and other components are fixed to the lower side of the door frame by the first embedded member 16 and the second embedded member 17, and the second clamping member 6 is fixed to the lower side of the radiation-proof door. When the sliding radiation-proof door is closed, the second inclined surface 7 on the second clamping member 6 contacts the first inclined surface 5 on the first clamping member 4, and the second clamping member 6 pushes the first clamping member 4, so that the first clamping member 4 drives the moving rod 3 to move upward. At this time, the moving rod 3 slides on the guide rod 8, and the spring 9 is compressed. Then the second clamping member 6 and the first clamping member 4 are in contact. The first clamping member 4 is clamped with each other to form a stable radiation-proof sealing structure. During this process, the first clamping member 4 drives the moving rod 3 to move upward, and the moving rod 3 drives the telescopic push rod 14 to lengthen from the initial shortest state. After the first clamping member 4 and the second clamping member 6 are clamped, the moving rod 3 moves down to the initial state, and the telescopic push rod 14 is also shortened to the shortest initial state. The spring 9 provides elastic force to further improve the stability of the clamping. During this process, the wavy sealing member 10 cushion is compressed after being stretched, and the sealing member 10 further improves the protection effect;
[0032] When opening the door, the motor 12 drives the bidirectional screw rod 11 to rotate, so that the sliders 13 on both sides move, and the sliders 13 drive the telescopic push rod 14 to move. At this time, the telescopic push rod 14 is in the shortest state, so that the telescopic push rod 14 acts on the moving rod 3, and the moving rod 3 moves up, driving the first clamping member 4 to move up and separate from the second clamping member 6. At this time, the protective door can be opened.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
