Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, the present embodiment provides a combination lock of a power distribution cabinet, including a combination lock body 1, where the combination lock body 1 has a touch screen, and further includes a killing device; the sterilizing device comprises a box body 21 and a box cover 22 which is rotationally connected with the box body 21, and the coded lock body 1 is arranged in the box body 21; the box body 21 is internally fixedly connected with a liquid storage bottle 3 filled with disinfectant, a pressing spray head 4 is arranged at the bottle mouth of the liquid storage bottle 3 and used for atomizing and spraying the disinfectant, the box cover 22 can seal the box body 21 and prevent dust from entering the box body 21 and attaching to a touch screen, a control mechanism is further arranged in the box body 21, when the box cover 22 is closed, the pressing spray head 4 is controlled by the control mechanism to perform spray disinfection, the control mechanism comprises a rotating shaft 51 rotationally connected with the box body 21, an eccentric wheel 52 and a gear 53 are sequentially arranged on the rotating shaft 51, a connecting column 54 is fixedly connected with the box cover 22, an arc-shaped rack 55 is fixedly connected at one end of the connecting column 54 far away from the box cover 22, and the circle center of the arc-shaped rack 55 is required to be coincident with the rotating axis of the box cover 22. When the box cover 22 is closed and the arc-shaped rack 55 is meshed with the gear 53, the rotating shaft drives the eccentric wheel 52 to rotate and continuously presses down the pressing nozzle 4 to spray and sterilize.

The following further describes with specific application scenario, when the power distribution cabinet needs to be opened by the staff, the box cover 22 is opened first, and then the touch screen on the coded lock body 1 in the box body 21 is input with a code to open the power distribution cabinet for working. When staff inputs the password, bacteria carried on hand can adhere to the touch screen, and when closing lid 22, control structure in box body 21 can press shower nozzle 4 with pressing down, and then make antiseptic solution atomizing blowout in the stock solution bottle 3, disinfect in the box body 21, just so make the use of trick lock more sanitary, healthy.

The specific process is as follows: the pressing head 4 itself has a spring for automatically resetting it. When the box cover 22 is closed, the arc-shaped rack 55 firstly contacts the gear 53 and is meshed with the gear 53, so that the rotating shaft 51 is driven to rotate, and the eccentric wheel 52 is further driven to press the pressing nozzle 4 to realize spraying and sterilizing. When the arc-shaped rack 55 completely passes through the gear 53 and is not meshed with the gear 53, the box cover 22 is closed again, but the rotating shaft 51 cannot rotate continuously due to no force between the connecting column 54 and the gear 53, the reset spring in the pressing nozzle 4 can enable the pressing nozzle 4 to reset automatically, spraying is not performed, and the whole eccentric wheel 52 and the rotating shaft 51 are pushed to rotate reversely slowly in the resetting process until the pressing nozzle 4 is reset completely.

On the whole, through setting up the disinfection device, utilize box body 21 and lid 22 to seal trick lock body 1, prevent that external dust from getting into, close lid 22 after using the trick lock, control structure can be immediately to pressing down shower nozzle 4 and make the antiseptic solution from in the stock solution bottle 3 blowout disinfect to the touch-sensitive screen in the box body 21, avoid remaining bacterium on the touch-sensitive screen for the trick lock of switch board uses more health, healthy.

Referring to fig. 2 to 4, as a specific implementation of the embodiment of the present application, a first torsion spring 6 is fixedly connected between the rotating shaft 51 and the case 21.

In combination with a specific use scenario, when the box cover 22 is closed, and in the process of meshing the arc-shaped rack 55 and the gear 53, the rotation of the rotating shaft 51 brings the first torsion spring 6 to generate torsion deformation, and when the arc-shaped rack 55 and the gear 53 are meshed, the box cover 22 is continuously closed again, and under the action of the first torsion spring 6, the rotating shaft 51 and the eccentric wheel 52 can reversely rotate along with the rotation, so that the pressure of the reset spring of the pressing nozzle 4 can be relieved, and the reset of the pressing nozzle 4 is quicker and smoother.

Referring to fig. 4 and 5, as a specific embodiment of the present application, a ratchet mechanism 7 is installed between a rotating shaft 51 and a gear 53, where it should be noted that the installation of the ratchet mechanism 7 needs to be guaranteed, when the lid 22 is closed, the gear 53 and the rotating shaft 51 rotate synchronously, and when the lid 22 is opened, relative rotation between the gear 53 and the rotating shaft 51 occurs through the ratchet mechanism 7, that is, the gear 53 continues to rotate under the meshing of the arc-shaped rack 55, and the rotating shaft 51 does not rotate.

In combination with a specific use scenario, firstly, it should be noted that when there is water mist on the touch screen, the problem of insensitive input may occur when the staff inputs the password, so when the lid 22 is closed, the pressing nozzle 4 needs to be triggered to spray, and when the lid 22 is opened, the pressing nozzle 4 is not triggered to spray any more.

Therefore, the control mechanism needs to ensure that when the box cover 22 is closed, the pressing spray head 4 is triggered to spray, in the process, the arc-shaped rack 55 firstly contacts the gear 53 and is meshed with the gear 53, then the gear 53 is driven to rotate, the rotating shaft 51 is driven to rotate by the ratchet mechanism 7, and the eccentric wheel 52 is driven to press the pressing spray head 4, so that spray sterilization is realized. When the arc-shaped rack 55 completely leaves the gear 53 and is not meshed with the gear 53, the box cover 22 is closed continuously, but no force acts between the connecting column 54 and the gear 53; at this time, under the action of the first torsion spring 6, the rotating shaft 51 rotates rapidly, the eccentric wheel 52 does not press the pressing nozzle 4 any more, and the pressing nozzle 4 is reset under the action of its own reset spring and is not spraying.

When the box cover 22 is opened, although the arc-shaped rack 55 still meshes with the gear 53, due to the arrangement of the ratchet mechanism 7, the rotating shaft 51 does not rotate, so that the eccentric wheel 52 does not rotate, the spraying condition can not occur when the box cover 22 is opened, the password input of a worker can not be influenced, and the use reliability of the coded lock is improved.

Furthermore, another advantage of installing the ratchet mechanism 7 is that: opening the cap 22 is more labor-saving. Without the ratchet mechanism 7, when the lid 22 is opened, the curved rack 55 and the gear 53 are meshed to rotate the rotating shaft 51, and further deform the first torsion spring 6, so that the first torsion spring 6 gives the rotating shaft 51 a reverse force to drive the rotating shaft 51 not to rotate, and therefore the first torsion spring 6 makes it relatively laborious to open the lid 22. After the ratchet mechanism 7 is arranged, the rotating shaft 51 can not rotate when the box cover 22 is opened, so that the box cover 22 is opened without being influenced by the first torsion spring 6, and the labor saving of opening the box cover 22 is improved.

Referring to fig. 1, as a specific implementation manner of the embodiment of the present application, a second torsion spring 8 is fixedly connected between a box cover 22 and a box body 21, when the box cover 22 is not opened, the second torsion spring 8 is not deformed, and the deformation amount of the second torsion spring 8 is gradually increased in the process of opening the box cover 22.

In combination with a specific use situation, when the box cover 22 is opened to convey the password, the coded lock is opened, the box cover 22 is loosened by a worker at the moment, the cabinet door can be automatically closed by the torsion force of the second torsion spring 8 until the rack touches the gear 53, then the worker can apply force again to close the box cover 22, and meanwhile, the disinfection work of the touch screen is also performed. After the coded lock is opened, a worker can open the cabinet door of the power distribution cabinet to work. Through the second torsion spring 8, after the staff inputs the password and loosens lid 22 and opens the cabinet door, the closing of lid 22 can close immediately, and then reminds the staff, forgets to close lid 22 after avoiding the staff to input the password for the work of disinfecting to the touch-sensitive screen can't go on, also makes outside dust unable to fall on the touch-sensitive screen.

Referring to fig. 1, as a specific embodiment of the present embodiment, a handle 9 is fixedly connected to a cover 22.

The power distribution cabinet is opened by combining specific use scenes and setting the handle 9, so that a worker can conveniently apply force to open the box cover 22 and then input passwords, and meanwhile, the box cover 22 can be conveniently closed, and the convenience of using the coded lock is integrally improved.

Referring to fig. 2 and 3, as a specific implementation manner of the embodiment of the present application, there are a plurality of liquid storage bottles 3, each liquid storage bottle 3 is filled with a disinfectant and is provided with a pressing nozzle 4, and the control mechanism is utilized to simultaneously press the plurality of pressing nozzles 4, so that spray sterilization can be simultaneously performed on the coded lock body 1 in the box body 21 from multiple points.

In combination with a specific use scene, the combination lock is sterilized from a plurality of points at the same time, so that the total amount of sterilization spray and the diffuse efficiency of the sterilization spray in the box body 21 can be improved, and the sterilization effect on the combination lock body 1 is improved.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
