Abstract
The utility model discloses a hub brake with a locking function. The hub brake comprises a rim, a hub brake housing, a central shaft sleeve in the rim and brake shoes, wherein a locking base sleeve is fixedly arranged in the hub brake housing; a locking spring plate with one end fixed on the locking base sleeve is arranged on the outer wall of the locking base sleeve; a locking latch is riveted with the middle of the locking spring plate; a through hole is formed in the locking base sleeve, in the position corresponding to the locking latch; locking grooves are formed in the outer wall of the central shaft sleeve; an anti-theft lock head is arranged on the hub brake housing and corresponds to the other end part of the locking spring plate; and a walking cam of the anti-theft lock head is matched with the end part of the locking spring plate. Compared with the prior art, the hub brake with the locking function has the advantages of compact structure, low cost, convenience in operation, good reliability, safety and concealment.
Description
Technical field
The utility model belongs to the brake part technical field, is specifically related to a kind of electronic nave boss with locking function for bicycle, battery-driven car and stops.
Background technology
Existing bicycle, electronic nave boss brake apparatus function are more single, do not possess the function of locking.Be to be provided with lockset in addition to its locking, as installing anti-theft column lock additional at handlebar, or adopting U-shape lock, chain lock to carry out locking, even be provided with many locks at vehicle that increased cost, safe antitheft is not high, and uses inconvenient.
Summary of the invention
For solving the above-mentioned defective that prior art exists, the purpose of this utility model is to provide a kind of compact conformation, and cost is low, has the locking function, safety, and electronic nave boss easy to use is stopped.
For achieving the above object, the technical solution adopted in the utility model: this electronic nave boss with locking function is stopped, has wheel rim, the hub shell of stopping, be positioned at the central axle sleeve of wheel rim and be installed on stop brake shoes on the shell of hub, it is characterized in that: described hub is stopped and is set with lock base cover in the shell, described lock base cover outer wall is provided with the locking shell fragment, one end of locking shell fragment is fixed on the lock base and puts, the middle part riveted joint of described locking shell fragment has the locking pellet shot from a slingshot, the lock base of locking pellet shot from a slingshot correspondence position puts and is provided with the through hole that the locking pellet shot from a slingshot passes, the outer wall of the central axle sleeve of corresponding locking pellet shot from a slingshot position is provided with the latching slot that the locking pellet shot from a slingshot can snap in, the hub of the described locking shell fragment the other end correspondence shell of stopping is provided with anti-theft lock end, the cam that moves about of described anti-theft lock end cooperates with the end of locking shell fragment, promotes the folding of locking shell fragment.
Described latching slot is 2 or 3 or 4.
Described locking shell fragment has the U-shaped bending part that increases its elastic force.
The hub in the described locking shell fragment outside is stopped and is provided with the backing pin that prevents that the locking shell fragment from excessively upspringing in the shell.
Adopt the beneficial effect of technique scheme: this electronic nave boss with locking function is stopped, it is the locking mechanism that has additional anti-theft lock end and tapered end control folding on the basis that the hub of existing battery-driven car or bicycle is stopped, rationally utilize the locus of hub in stopping, compact conformation, hub is stopped possessed the locking function, the wheel hub of vehicle can't be advanced after by locking, and the lockset position is hidden, reach antitheft purpose, safety is good.Vehicle is when normal the use, and the cam that moves about of anti-theft lock end backs down the locking shell fragment, and the locking pellet shot from a slingshot at locking shell fragment middle part is ejected the latching slot of central axle sleeve, and central axle sleeve can recover to rotate, and vehicle can move ahead or retreat.When the needs locking, the rotation anti-theft lock end, the cam that moves about discharges by the locking shell fragment of jack-up, the locking shell fragment resets under the effect of self elastic force, drive the locking pellet shot from a slingshot and make in its latching slot that snaps in central axle sleeve, the wheel hub of vehicle can't rotate, and reaches the antitheft purpose of lock car.Compared with prior art, have compact conformation, cost is low, and is easy to operate, and good reliability is safe and out of sight.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is the hub of the present utility model shell structure scheme drawing of stopping.
Fig. 2 is rim structure scheme drawing of the present utility model.
The specific embodiment
As Fig. 1, the electronic nave boss with locking function shown in 2 is stopped, has wheel rim 10, the hub shell 1 of stopping, be positioned at the central axle sleeve 11 of wheel rim and be installed on stop brake shoes on the shell of hub, described hub is stopped, and shell is interior to be set with lock base cover 9 by screw 8, described lock base cover outer wall is provided with locking shell fragment 3, described locking shell fragment has the U-shaped bending part 2 that increases its elastic force, one end of locking shell fragment overlaps on 9 at the lock base by the rivet rivet clasp, the middle part riveted joint of described locking shell fragment has locking pellet shot from a slingshot 4, the lock base of locking pellet shot from a slingshot correspondence position puts and is provided with the through hole 5 that the locking pellet shot from a slingshot passes, the outer wall of the central axle sleeve of corresponding locking pellet shot from a slingshot position is provided with the latching slot 12 that the locking pellet shot from a slingshot can snap in, and latching slot 12 is 2 or 3 or more.The hub of the described locking shell fragment the other end correspondence shell of stopping is provided with anti-theft lock end, and the cam 7 that moves about of described anti-theft lock end cooperates with the end of locking shell fragment, promotes the folding of locking shell fragment.The hub in the described locking shell fragment outside is stopped and is provided with the backing pin 6 that prevents that the locking shell fragment from excessively upspringing in the shell.
