DETAILED DESCRIPTION
[0020] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a ball mill control cabinet, comprising a control cabinet body 1, a locking block 2 is fixedly connected to the front of the control cabinet body 1, a cabinet door 3 is hinged to the front of the control cabinet body 1 through a hinge, a mounting box 4 is fixedly connected to the front of the cabinet door 3, a fingerprint identifier 5 is fixedly installed on the front of the mounting box 4, and a rotating rod 6 is installed on the rear inner wall of the mounting box 4 through a bearing;
[0022] The outer surface of the rotating rod 6 is provided with a locking device, and the locking device includes a flat gear 7 , and the inner wall of the flat gear 7 is fixedly sleeved with the outer surface of the rotating rod 6 .
[0023] Furthermore, a locking groove 71 is provided on the front of the rotating rod 6, and a limiting sliding groove 72 is provided on the rear inner wall of the installation box 4. The inner wall of the limiting sliding groove 72 is slidably connected to the limiting slider 73. The rotating rod 6 drives the flat gear 7 to rotate stably through the cooperation of the bearing, and the locking block 2 cooperates with the cabinet door 3 to close and lock it, thereby improving safety.
[0024] Furthermore, a rack 74 is fixedly connected to the front of the limit slider 73, and the tooth surface of the rack 74 meshes with the tooth surface of the spur gear 7. An insert block 75 is fixedly connected to the lower surface of the rack 74. The rack 74 moves stably through the cooperation of the limit slider 73, thereby driving the insert block 75 to move stably.
[0025] Furthermore, one end of the plug block 75 passes through and extends to one side surface of the installation box 4, and the outer surface of one end of the plug block 75 is movably plugged into the inner wall of the locking block 2. A blind hole 76 is provided on the front side of the installation box 4, and the plug block 75 is movably plugged into the locking block 2 to play a role of limiting and fixing.
[0026] Furthermore, a driving rod 77 is movably inserted into the inner wall of the blind hole 76, and a key 78 is fixedly connected to one end of the driving rod 77. The outer surface of the key 78 is movably inserted into the inner wall of the lock groove 71, and one end of the driving rod 77 contacts the front side of the rotating rod 6. The blind hole 76 facilitates the insertion of the driving rod so that the key 78 can be inserted into the lock groove 71 to cooperate, thereby realizing the rotation of the rotating rod 6 by the driving rod 77.
[0027] Furthermore, the other end of the driving rod 77 is fixedly connected to a driving handle 79, a ratchet 710 is fixedly sleeved on the outer surface of the rotating rod 6, a positioning rod 711 is installed on the rear inner wall of the mounting box 4 through a bearing, and a pawl 712 is fixedly sleeved on the outer surface of one end of the positioning rod 711, and one end of the pawl 712 is rotatably engaged with the tooth surface of the ratchet 710. The driving handle 79 serves to facilitate the rotation of the driving rod 77, and the cooperation between the ratchet 710 and the pawl 712 serves to limit the rotation of the rotating rod 6.
[0028] Furthermore, a torsion spring 713 is movably sleeved on the outer surface of the positioning rod 711, one end of the torsion spring 713 is fixedly connected to the rear inner wall of the installation box 4, and the other end of the torsion spring 713 is fixedly connected to the back side of the pawl 712. A micro-servo electric cylinder 714 is fixedly installed on the inner top wall of the installation box 4, and one end of the piston rod of the micro-servo electric cylinder 714 is fixedly connected to a connecting rope 715, and one end of the connecting rope 715 is fixedly connected to one side surface of the pawl 712. The reset elastic force of the torsion spring 713 plays a role in driving the pawl 712 to swing and reset through the cooperation of the positioning rod 711, and the retraction movement of the piston rod of the micro-servo electric cylinder 714 plays a role in driving one end of the pawl 712 to swing through the connecting rope 715.
[0029] Through the locking device, the cabinet door 3 is double locked and limited, avoiding opening the cabinet door 3 with a single key, thereby improving the safety of the control cabinet body 1 and solving the problem that the cabinet door 3 is currently opened by a limit structure, which makes internal electronic components easy to be stolen and easily causes personal safety hazards.
[0030] Working principle: Step 1, when opening the cabinet door 3, it is necessary to first pass the identification of the fingerprint identifier 5. After successful identification, the piston rod of the micro-servo electric cylinder 714 contracts, thereby driving the pawl 712 to swing through the connecting rope 715. The swing of the pawl 712 causes one end of it to break away from the limit of the ratchet wheel 710. At this time, the staff inserts the driving rod 77 from the blind hole 76, and inserts the key 78 into the lock slot 71 for positioning, thereby driving the driving rod 77 and the rotating rod 6 to rotate synchronously through the cooperation of the driving handle 79;
[0031] When the locking cam 72 is in the closed position, the locking cam 73 is in the closed position, and the locking cam 73 is in the closed position, so that ...
[0032] Step three, when the fingerprint identifier 5 fails to identify the user, the stranger inserts the drive rod 77 from the blind hole 76 and inserts the key 78 into the lock slot 71 for positioning. However, due to the locking cooperation between the ratchet 710 and the pawl 712, the drive rod 77 cannot drive the rotating rod 6 to rotate clockwise, so that the cabinet door 3 cannot be opened by a single drive rod 77 and key 78, thereby improving the safety of the control cabinet body 1.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
