DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It is understandable that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for ease of description, only the parts related to the utility model rather than all structures are shown in the drawings. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] A power distribution cabinet equipped with a fingerprint lock, such as Figure 1-11 As shown, it includes: a cabinet, a protection box and a fingerprint lock, the fingerprint lock has a fingerprint recognition module, the protection box is fixedly connected to the outer surface of the cabinet, a cavity is arranged inside the protection box, and the fingerprint recognition module is arranged in the protection box;

[0036] The protection box includes a box body, a cover plate, a rotating shaft, a torsion spring and a pull rope; the front end face of the box body has an opening, the cover plate is rotatably connected to the box body and snapped into the opening, the cover plate is a rectangular sheet structure, the right edge of the cover plate is hinged to the right edge of the box body opening, the hinge shaft between the cover plate and the box body protrudes from the front end face of the box body, the rotating shaft is located inside the box body and is vertically arranged, the rotating shaft is rotatably connected to the upper surface of the inner side of the box body, a torsion spring for resetting the rotating shaft is arranged on the rotating shaft, one end of the pull rope is fixedly connected to the rotating shaft and the pull rope is wound around the outer surface of the rotating shaft, and the other end of the pull rope is fixedly connected to the rotating shaft. The cover is close to one end of the box; the protection box provides protection for the fingerprint recognition module, solves the shortcomings of the prior art, and avoids the recognition failure or even damage of the fingerprint recognition module due to wind, sun, rain and exposure. When the staff opens the fingerprint lock, they flip open the cover, and the cover pulls the pull rope to drive the rotating shaft to rotate. The torsion spring is deformed under the force. After the fingerprint recognition module is unlocked, the torsion spring resets and drives the rotating shaft to rotate. The rotating shaft reels the pull rope, so that the cover closes automatically, avoiding the risk of inadequate protection of the fingerprint recognition module due to personnel forgetting to close the cover.

[0037] Furthermore, the protection box also includes a generator, a battery, an electromagnet and a magnetic attraction part; the generator and the battery are electrically connected and fixedly installed inside the box, the generator includes a stator and a rotor, the stator is fixedly connected to the box, the rotor is fixedly connected to the rotating shaft, the battery is electrically connected to the electromagnet, the electromagnet is fixedly connected to the box, and the magnetic attraction part is fixedly connected to the end face of the cover away from the box; when the rotating shaft rotates, the rotor is driven to rotate the generator to generate electricity and store electrical energy in the battery, when the magnetic attraction part contacts the electromagnet, the battery supplies power to the electromagnet, the electromagnet absorbs the magnetic attraction part and keeps the cover in an open state, after more than ten seconds, the battery is exhausted, the electromagnet loses its magnetism, the cover is reset, and the cover has a demonstration closing function, which further facilitates the staff to use the fingerprint recognition module.

[0038] Wherein, the electromagnet is fixedly connected to the box body through a bracket.

[0039] Optionally, the magnetic attraction portion is a handle structure; the magnetic attraction portion can be attracted by the electromagnet and can also be used as a handle, which simplifies the structure and reduces manufacturing costs.

[0040] A better solution is to set a transmission between the shaft and the rotor. The transmission is composed of multiple gear sets, the shaft is fixedly connected to the small gear, and the rotor is fixedly connected to the large gear. The transmission increases the speed of the shaft and drives the rotor to rotate, so that the generator can provide more electrical energy.

[0041] Optionally, a shock absorber is provided between the cover plate and the box body.

[0042] Among them, the shock absorber includes a contact piece and an elastic part. The contact piece is made of flexible material, and the two ends of the elastic part are fixedly connected to the contact piece and the box body respectively. When the cover is about to close, the speed of the cover is slowed down under the action of the elastic part after it contacts the contact piece, thereby avoiding the rigid impact between the cover and the box body, which is beneficial to extending the service life of the protective box.

[0043] A structure worth adding is that a sealing ring is provided at the open end of the box, and the sealing ring is made of rubber; the sealing ring can prevent dust and the like from entering the protective box, further improving the protective effect.

[0044] The protection box also includes connecting ears, which are provided in plurality and fixedly connected to the rear end face of the box body. The connecting ears are provided parallel to the rear end face of the box body, and threaded connecting holes are provided on the connecting ears, so that the protection box can be conveniently fixed to the power distribution cabinet.

[0045] When there is space inside the power distribution cabinet, an opening can be reserved on the surface of the power distribution cabinet. The protection box is embedded in the power distribution cabinet. The protection box also includes a wrapping strip, which is fixedly connected to the opening end of the box body and extends to all sides.

[0046] When in use, the staff opens the cover 90 degrees through the magnetic attraction part, and the cover pulls the drawstring, which drives the rotating shaft to rotate. The rotation of the rotating shaft causes the torsion spring to elastically deform. The rotation of the rotating shaft drives the rotor to rotate through the transmission and then the generator generates electricity. The electrical energy is stored in the battery. When the magnetic attraction part contacts the electromagnet, the battery discharges to cause the electromagnet to generate magnetic force and last for more than ten seconds. After that, the battery is exhausted and the electromagnet loses its magnetic force. The torsion spring drives the rotating shaft to rotate in the opposite direction under the action of elastic force, and the reel drawstring cover is reset. When the cover is about to close, the cover contacts the contact piece and the speed is slowed down under the action of the elastic part, thus avoiding the rigid impact between the cover and the box.

[0047] The above description is only an implementation method of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present utility model.
