Therefore, door stoppers are generally provided at the entrance and exit of the inspection door, and the door stoppers are used to limit the opening of the inspection door during the inspection process. In the prior art, the door stopper can be opened after the detection is finished. At this time, the detection door collides with the door stopper because the worker is anxious or forgets to wait for directly pushing the detection door open. The door stopper can be damaged in advance under the action of too violent force or long time. To solve the above problems.
The whole body surface contamination monitor door stopper and the detection door scheme provided by the embodiments of the present invention will be described in detail through several specific embodiments.
Please refer to fig. 1, which illustrates an overall structure diagram of a door stopper of a whole body surface contamination monitor of the present invention, the door stopper of the whole body surface contamination monitor is used for a detection door 1 of the whole body surface contamination monitor, comprising: bearing body 3, shutter body 2, elastic component 5 and removal portion 10, wherein:
the door stopper comprises a door stopper body 2, wherein the door stopper body 2 is rotatably connected to the bearing body 3. The shutter body 2 is a member for blocking the detection door 1 when the detection door 1 is opened, and the shutter body 2 may be rod-shaped, plate-shaped, or block-shaped.
A carrier body 3. The rotary door is used for bearing the weight of the door body 2 and enabling the door body 2 to rotate relative to the door body 2, and the rotation of the door body 2 relative to the bearing body 3 can enable the door body 2 to convert hard impact force into flexible rotary force when the door body 2 is collided by the detection door 1. And the impact is finally buffered by the elastic member 5, referring to fig. 3, fig. 3 illustrates an operation diagram of the shutter body 2 moving to a position a when the shutter body 2 receives the pushing force of the detection door 1. The bearing body 3 is connected with the working end of the moving part 10, and the bearing body 3 can move or rotate under the driving of the working end of the moving part 10. And the bearing body 3 can drive the shutter body 2 to move or rotate when moving or rotating. The carrier body 3 may be rod-shaped, plate-shaped or block-shaped.
In an example, the whole body surface contamination monitor door stopper further comprises an arc-shaped guide rail 7, the arc-shaped guide rail 7 is arranged between the bearing body 3 and the door stopper body 2, and the door stopper body 2 rotates along the guide direction of the arc-shaped guide rail 7. When the shutter body 2 and the bearing body 3 are rotatably connected, the shutter body 2 is more stable in rotation by adding the arc-shaped guide rail 7 in consideration of the stability of rotation of the shutter body 2, and the durability of the whole device is improved. And because the elastic piece 5 is arranged between the shutter body 2 and the bearing body 3, the elastic piece 5 is more stable when in action. Adopt arc guide rail 7 to lead to the rotation of shutter body 2, make elastic release and the elastic contraction of elastic component 5 more stable, ensure elastic component 5's durability to make shutter body 2 can be stable rotate on bearing body 3, avoid elastic component 5 to lose original shape and the dead phenomenon of card appears and take place.
The elastic piece 5 is arranged between the bearing body 3 and the shutter body 2, and the elastic piece 5 is used for providing a buffering force for the shutter body 2 when the bearing body 3 rotates relative to the shutter body 2 under the thrust of the detection door 1; and when the shutter body 2 is not pushed, the relative positions of the shutter body 2 and the bearing body 3 are restored. Referring to fig. 1, the elastic member 5 may be a torsion spring, a tension spring or a compression spring.
In one example, a second rotating shaft is arranged between the bearing body 3 and the shutter body 2, and the axis of the second rotating shaft coincides with the arc center of the arc-shaped guide rail 7. The elastic part 5 can be a torsion spring, the torsion spring is sleeved on the second rotating shaft, one end of the torsion spring is connected with the bearing body 3, and the other end of the torsion spring is connected with the shutter body 2.
In another example, the elastic member 5 may be a tension spring disposed between the bearing body 3 and the shutter body 2 on a side close to the inspection door 1.

In another example, the elastic member 5 may be a compression spring disposed between the bearing body 3 and the door body 2 on a side away from the inspection door 1. When the detection door 1 pushes away to apply force to the shutter body 2, the shutter body 2 rotates relative to the bearing body 3, and the compression spring is compressed to collect energy.
The working end of the moving part 10 is connected with the bearing body 3, and the moving part 10 is used for driving the bearing body 3 to change the position of the door stopper body 2, so that the door stopper body 2 can block and release the blocking of the detection door 1.
For example, the moving part 10 is a guide rail, and the bearing body 3 is connected with a slide block of the guide rail; the sliding block can move to at least a first position and a second position, and when the sliding block is located at the first position, the shutter body 2 is used for blocking the detection door 1; when the slide block is located at the second position, the shutter body 2 is located at the outer side of the detection door 1. When the moving part 10 is a guide rail, the slider may be manually pushed or driven by a linear motion device as a power source. Wherein the linear motion device may be a combination of a motor and a ball screw. Or the linear motion device may be a cylinder.
For another example, the moving part 10 is a rotating shaft, the bearing body 3 is connected to the rotating shaft, and the rotating shaft can rotate the bearing body 3 relative to the detection door 1; the shutter body 2 can rotate to at least a third position and a fourth position under the action of the rotating shaft, and when the bearing body 3 is located at the third position, the shutter body 2 blocks the detection door 1; when the bearing body 3 is located at the fourth position, the shutter body 2 is located at the outer side of the detection door 1. When the moving part 10 is a rotating shaft, a manner of manually rotating the rotating shaft may be adopted. The mode of driving the rotating shaft by the motor can also be adopted.
To sum up, through will bearing the body and the shutter body rotates to be connected to set up the elastic component between bearing the body and the shutter body, make and bear the body and the shutter body also can have certain rotation in the business turn over direction that detects the door. When a worker pushes the detection door away by misoperation during the door stopping process of the door stopper, the force of the detection door acts on the door stopping body, and the door stopping body can rotate outwards along with the pushing direction of the detection door. Finally, the elastic member provides a buffering force for the buffering force stop door body, and the buffering force can be applied to the detection door and is sensed by a worker. The workman can close the detection door this moment, cancels the effort that the detection door applyed to the shutter body to open the detection door when the shutter body no longer blocks the detection door. And then make the utility model discloses whole-body surface contamination monitor shutter ware is not fragile, and life increases.
