Abstract
The invention discloses an anti-wrong-opening mechanism of a protection cover of a water dispenser. The protection cover covers a body. The front portion of the body is connected with a lock catch in a rotating mode. The lock catch is shaped like a falcate. A claw used for grabbing the front end flange of the protection cover is arranged on the head portion of the lock catch. A base is arranged on the front portion of the body. A U-shaped installation groove is formed in the front portion of the base. A rotating shaft is fixed into the installation groove. A front locking groove is formed in the portion, in front of the base, of the side wall of the installation groove. Meanwhile, an upper locking groove is formed in the upper portion of the base. A locking pin parallel to the rotating shaft is arranged on the portion, over the rotating shaft, of the lock catch. The two ends of the locking pin protrude out of the outer side wall of the lock catch. A spring is connected between the locking pin and the rotating shaft. A transversely-through vertical groove is formed in the lock catch and can make the locking pin move up and down. The protection cover can be prevented from wrong opening, and safety is improved.

Summary of the invention
Technical problem to be solved by this invention is just to provide the anti-error opener of a kind of water dispenser protective cover, avoids the anti-error unlatching of protecting cover, improves security.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the anti-error opener of a kind of water dispenser protective cover, protective cover is covered on body, body portion is rotationally connected a snap close, described snap close is sickleshaped, snap close head is provided with the hook of grabbing conjunction with protective cover front end chimb, described body portion is provided with a pedestal, pedestal front portion is provided with a U-shaped mounting groove, mounting groove internal fixtion one rotating shaft, sidewall locked groove before the front of pedestal is provided with of mounting groove, above pedestal, be provided with locked groove simultaneously, latch in also to be provided with directly over rotating shaft one with the lock pin of shaft parallel, the two ends of lock pin protrude from snap close lateral wall, spring is connected with between lock pin and rotating shaft, the vertical slot that described snap close is provided with a lateral direction penetrating can make lock pin up and down, under snap close and protective cover lock-out state, under spring tension effect, the two ends of lock pin are connected in locked groove, under snap close and protective cover released state, under spring tension effect the two ends of lock pin be connected in before in locked groove, the height of described vertical slot is enough to make lock pin depart from locked groove.
As preferably, described lock pin connects a draw ring, and described draw ring is U-shaped, and the two ends of draw ring oral area and lock pin are fixed.
As preferably, the cross section of described snap close is U-shaped, and described vertical slot is located at U-shaped two side.
As preferably, described vertical slot is located at directly over rotating shaft, and described lock pin is through described vertical slot.
As preferably, be arc-shaped transitional surface between sidewall the past locked groove to upper locked groove of described mounting groove.
The present invention makes snap close lock by lock pin with coordinating of upper locked groove, upwards rotate snap close, after snap close and protective cover lock, due to spring tension, spring pulls down lock pin, and the two ends of lock pin are connected in locked groove to deviate from, now due to the acting in conjunction of rotating shaft and lock pin, snap close cannot rotate, and protecting cover therefore can be avoided to open by mistake and open, and improves security.
If need to separate opening lock catch, upwards zip pin, upper locked groove is deviate from the two ends of lock pin, and snap close unlocks, and now, snap close can around axis of rotation, and finally rotate snap close and be connected in front locked groove at the two ends of lock pin, snap close locks again.

Detailed description of the invention
The embodiment 1 of first composition graphs 1 to Fig. 5 to the anti-error opener of a kind of water dispenser of the present invention protective cover does preliminary explanation below, protective cover 30 is covered on body 3, body portion is rotationally connected a snap close 2, described body portion is provided with a pedestal 1, pedestal front portion is provided with a U-shaped mounting groove, mounting groove internal fixtion one rotating shaft 12, sidewall locked groove 10 before the front of pedestal is provided with of mounting groove, above pedestal, be provided with locked groove 11 simultaneously, latch in also to be provided with directly over rotating shaft one with the lock pin 23 of shaft parallel, the two ends of lock pin protrude from snap close lateral wall, spring 13 is connected with between lock pin and rotating shaft.
Further, the vertical slot 21 that described snap close is provided with a lateral direction penetrating can make lock pin up and down, under snap close and protective cover lock-out state, under spring tension effect, the two ends of lock pin are connected in locked groove, under snap close and protective cover released state, under spring tension effect the two ends of lock pin be connected in before in locked groove, the height of described vertical slot is enough to make lock pin depart from locked groove.
Further, described snap close is sickleshaped, and snap close head is provided with the hook 22 of grabbing conjunction with protective cover front end chimb 31.The cross section of described snap close is U-shaped, and described vertical slot is located at U-shaped two side.Described vertical slot 21 is located at the bottom of snap close, and described rotating shaft 12 is through described vertical slot.The sidewall of described mounting groove is arc-shaped transitional surface between locked groove to upper locked groove in the past.Described front locked groove and upper locked groove are semicircular groove.Lock pin 23 is through the pin-and-hole 20 of snap close U-shaped two side.
In the present embodiment, can direct pull snap close, thus make lock pin depart from locked groove, after snap close and protective cover lock, due to spring tension, spring pulls down pendulum lock pin and snap close, the two ends of lock pin are connected in locked groove to deviate from, now due to the acting in conjunction of rotating shaft and lock pin, snap close cannot rotate, and protecting cover therefore can be avoided to open by mistake and open.
If need to separate opening lock catch, upwardly push button, snap close pull-up, upper locked groove is deviate from the two ends of lock pin, and snap close unlocks, and now, snap close can around axis of rotation, and finally rotate snap close and be connected in front locked groove at the two ends of lock pin, snap close locks again.
