[0013] Compared with the prior art, the mouse guard plate has the following beneficial effects:

[0014] 1. In the utility model, when personnel or equipment enters, the mouse blocking plate has force, the locking bead lock locking part of the bead lock lock body is separated from the bead lock lock body, and the mouse blocking plate is opened; when personnel enters, the mouse blocking plate is automatically closed and gradually reset through the automatic door closing effect of the door closer and the spring hinge. When the mouse has force on the mouse blocking plate, the mouse blocking plate cannot be opened due to its small weight, the magnetic attraction force of the first magnetic attraction plate and the second magnetic attraction plate and the force of the pressure spring, and the mouse blocking purpose is achieved. Since the mouse blocking plate does not need to be removed when personnel enters, the operation steps when entering are not increased, and the possibility of forgetting to reinstall the mouse blocking plate is eliminated. The height of the mouse blocking plate is not too high for the height of the person, but the person needs to pay attention to the position of the mouse blocking plate and cross the mouse blocking plate, the personnel entering and exiting is relatively troublesome, and the mouse blocking plate needs to be removed when the equipment enters and exits, and then reinstalled after the equipment passes, which is not simple to use.

[0015] 2. In the utility model, through the automatic door closing effect of the door closer and the spring hinge, the mouse blocking plate is automatically closed and gradually reset, and under the magnetic attraction of the first magnetic attraction plate and the second magnetic attraction plate, the locking core of the locking bead lock moves between the two bead main bodies, which can avoid the possibility that the mouse blocking plate cannot be completely reset due to the decrease of force when the mouse blocking plate is reset to the original position, and assist in completing the automatic door closing function of the mouse blocking plate.

[0016] 3. In the utility model, the outer end of the outer fixed sleeve is connected with a threaded locking column through threads, and the force of the pressure spring when the bead main body compresses the locking core is different through the inward or outward rotation of the threaded locking column, so as to adjust the locking force of the entire locking bead lock, which can be adjusted according to the mass of mice in different areas to ensure that the locking bead lock will not be opened due to the collision of mice.

[0017] 4. In the utility model, when applied to a workshop or warehouse with a larger door width, the two mouse blocking plates are connected through the screw connection of the upper hole of the first connecting hinge and the third mounting hole of the mouse blocking plate; and the two mouse blocking plates are connected through the screw connection of the upper hole of the second connecting hinge and the third mounting hole on the other side of the second mouse blocking plate, completing the connection of the three mouse blocking plates, so that the overall length of the entire mouse blocking structure can be expanded, matching the workshop or warehouse with a larger door width, and the applicability is wider. When the equipment passes, the first connecting hinge and the second connecting hinge can be rotated to fold the multiple mouse blocking plates, and then rotate the folded mouse blocking plates to reduce the radius of rotation, that is, the increase of the number of mouse blocking plates will not increase the overall radius of rotation, and a larger space is not needed for rotation, saving space.

[0018] 5. In the utility model, when the mouse-proof plate is folded, the connecting tension spring is in the stretching or shrinking state when folding outside or inside; after the equipment passes, no force is applied to the mouse-proof plate to make it fold, under the action of the connecting tension spring, each mouse-proof plate resets, and the whole resets through the door closer and the spring hinge, manual resetting is not needed, and the operation steps are saved. The existence of the connecting tension spring makes the multiple mouse-proof plates be horizontally arranged as a whole structure without large external force, personnel do not need to fold the mouse-proof plate when entering and exiting, the normal personnel entering and exiting are not affected, and the foldable nature does not affect the convenience of use.
