Description
Technical field
The utility model relates to the case lid on a kind of urea box.
Background technique
In order to prevent the urea solution in urea box stolen, generally urea case lid can be arranged to anti-theft, in prior art, this antitheft urea case lid structure species is various, but general part is more, and structure is comparatively complicated, manufactures inconvenient.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provide a kind of structure more reasonable, manufacture more convenient antitheft urea box case lid.
The technical scheme in the invention for solving the technical problem is:
A kind of antitheft urea box case lid, comprise the inner casing be tightened on urea box case mouth and the spiral cover be set in outside inner casing, described spiral cover can drive described inner casing to rotate, it is characterized in that: between described spiral cover and inner casing, lock core is set, the top of described lock core is fixed in spiral cover, the bottom of described lock core is located in a gear, described lock core and gear wear described inner casing, described inner casing internal surface is provided with a circle gear ring, gear ring described in described gears meshing connects, the internal surface of described gear is provided with ratchet, the dead bolt of described lock core is provided with ratchet, between dead bolt and lock core, latch bolt spring is set, the ratchet described in the engageable connection of ratchet of described dead bolt or exit described ratchet.
As preferably, between lock core and inner casing, be provided with spring.
As preferably, the lock core hole of lock core exposes at spiral cover upper surface, and the top of described lock core hole is covered with waterproof cover, and one end of described waterproof cover is connected on spiral cover by axis of rotation.
As preferably, the outer surface of inner casing lower end is provided with scrobicular ring, is arranged with anti-lost circle in described scrobicular ring.
Case lid includes inner casing and the spiral cover be set on inner casing, is tightened on case mouth or spins down by spiral cover by inner casing.By the setting of lock core, spiral cover drives inner casing to rotate, or the relative inner casing idle running of spiral cover.Detailed process is, when key inserts in lock core hole, when unblanking, dead bolt on lock core produces, then the ratchet in the ratchet occlusion gear on dead bolt, because gears meshing connects inner casing, now, when hand-held spiral cover rotates spiral cover, spiral cover can be driven to rotate, namely realize spiral cover and drive inner casing to be tightened onto case mouth or unscrew disengaging case mouth.When latching, the ratchet on dead bolt exits the ratchet on gear, and now spiral cover cannot driven gear and inner casing rotate, and realizes idle running, then achieves anti-theft feature.Owing to there is gap between inner casing and spiral cover, can abnormal sound be caused, therefore be provided with damping spring between the lower end and inner casing of lock core, avoid this abnormal sound to produce.
Be provided with latch bolt spring between dead bolt and lock core, then, when screwing, spiral cover can drive inner casing to rotate, after screwing, external force is comparatively large, and now, the ratchet of dead bolt skids off ratchet, spiral cover opposed gear idle running again, and between ratchet and ratchet, send card card sound, signal case lid screws.When unscrewing in the other direction, then do not affect.
Above the lock core hole of spiral cover, lid establishes a waterproof cover, and waterproof cover is rotatably connected on spiral cover, then waterproof cover left-right rotation can be opened or close.The outer surface of inner casing lower end is provided with scrobicular ring, is arranged with anti-lost circle in described scrobicular ring.
The utility model realizes the connection of dead bolt and gear by lock core, and realizes the connection of spiral cover and inner casing by gear transmission moment.In addition due in the drive rotation of spiral cover and inner casing or idle cycle, gear is an easily damaged parts, therefore it is independent from original inner casing, if damaged, arbitrarily can change, and need not change whole inner casing.
The beneficial effects of the utility model are: the utility model, by the reasonable setting to structure, makes case lid overall structure simple, easily manufactured, and superior performance.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, 3, a kind of antitheft urea box case lid, comprise the inner casing 8 be tightened on urea box case mouth and the spiral cover 2 be set in outside inner casing, spiral cover can drive described inner casing to rotate.Be equipped with lock core 3 between spiral cover 2 and inner casing 8, the top of lock core 3 is fixed in spiral cover, and the bottom of described lock core is located in a gear 5, and lock core and gear wear in inner casing 8 jointly.Inner casing internal surface is provided with a circle gear ring 7, the gear ring 7 that gear 5 is connected with a joggle described, the internal surface of gear is provided with ratchet 10, the dead bolt 4 of lock core is provided with ratchet 11, between dead bolt 4 and lock core, latch bolt spring is set, the ratchet 10 described in the engageable connection of ratchet 11 of dead bolt or exit described ratchet.Be provided with spring 6 between lock core and inner casing, owing to there is gap between inner casing and spiral cover, can abnormal sound be caused, therefore be provided with the spring for cushioning between the lower end and inner casing of lock core, avoid this abnormal sound to produce.The lock core hole of lock core exposes at spiral cover upper surface, and the top of described lock core hole is covered with waterproof cover 1, and one end of waterproof cover is connected on spiral cover by axis of rotation, then waterproof cover left-right rotation can be opened or close.The outer surface of inner casing lower end is provided with scrobicular ring, is arranged with anti-lost circle 9 in described scrobicular ring.
Case lid includes inner casing and the spiral cover 2 be set on inner casing, is tightened on case mouth or spins down by spiral cover by inner casing 8.By the setting of lock core, spiral cover drives inner casing to rotate, or spiral cover rotates relative to inner casing.Detailed process is, when key inserts in lock core hole, when unblanking, dead bolt 4 on lock core produces, then the ratchet 11 on dead bolt is engaged the ratchet 10 in gear, because gear 5 is connected with a joggle inner casing, now, when hand-held spiral cover rotates spiral cover, spiral cover can be driven to rotate, namely realize spiral cover and drive inner casing to be tightened onto case mouth or unscrew disengaging case mouth.When latching, the ratchet 11 on dead bolt exits the ratchet 10 on gear, and now spiral cover cannot driven gear and inner casing rotate, and realizes idle running, then achieves anti-theft feature.Be provided with latch bolt spring between dead bolt and lock core, then, when screwing, spiral cover can drive inner casing to rotate, after screwing, external force is comparatively large, and now, the ratchet of dead bolt 4 skids off ratchet, spiral cover opposed gear idle running again, and between ratchet and ratchet, send card card sound, signal case lid screws.When unscrewing in the other direction, then do not affect.
The utility model realizes the connection of dead bolt and gear by lock core, and realizes the connection of spiral cover 2 and inner casing 8 by gear 5 carry-over moment.In addition due in the drive rotation of spiral cover and inner casing or idle cycle, gear 5 is easily damaged partss, therefore it is independent from original inner casing, if damaged, arbitrarily can change, and need not change whole inner casing.
The utility model, by the reasonable setting to structure, makes case lid overall structure simple, easily manufactured, and superior performance.
