Description

Tension rod and rotary clock for bicycle

The utility model belongs to a kind of lock.

The lock that is widely used at present is an inserted link lock, and its structure is that lock body and inserted link two parts are formed, and the lock core of lock body is the side assembling, utilizes the lock dog of lock core to be stuck in the breach of locking bar and realizes locking.Above lock body, have jack, use so that deposit locking bar.This lock construction is simple, and it is good to take precautions against performance, and its shortcoming is that locking bar breaks away from lock body, will locking bar after unblanking inserts in the jack on the lock body, uses inconvenience, makes in the process, and the lock body punching increases man-hour, long-term use, the locking bar plug difficulty of getting rusty.

For solving above deficiency, the purpose of the utility model provides a kind of pull bar rotary vehicle beam-inserted lock, utilizes runing rest that locking bar and lock body are closely cooperated, to reach structure processing, purpose reasonable in design, easy to use.

Structure design of the present utility model is achieved in that the structure of whole lock is by lock body, locking bar and rotary fixed bracket are formed (abbreviation fixed support) (as shown in Figure 1), its lock body is made up of housing and lock core, the vertical lock body of lock core is positive assembling, locking plate is equipped with in inner end at lock core, locking plate is enclosed within and is symmetrical blading shape on the lock core, have little semicircle fore shaft in corresponding position, symmetrical blading both sides, the lock core spring is housed on the lock core on locking plate top, the locking plate spring is housed below locking plate, lock core and locking plate are restricted by individual spring certainly separately, and leave small surplus when assembling between lock core and the locking plate, the locking plate both sides are fixed bolt hole, and the locking plate spring is enclosed within on the bolt hole of one of them simultaneously; Relative both sides, locking bar end have fore shaft, inwardly there is 5 ° inclination on fore shaft plane, the outside, so that when locking and the automatic interlock of locking plate bayonet socket, relative two sides is fixed with alignment pin separately outside the fore shaft of locking bar termination, in the locking bar inner end rotary fixed bracket is housed, be rotating shaft in the middle of the fixed support, rotating shaft has the horizontal jack (as shown in Figure 2) corresponding with locking bar with fixed support, and on fixed support, have upwards notch with the locking bar correspondence position, the notch below has and the corresponding jack of inserted link vertically downward equally with fixed support, all there are umbilicate clamping plate lock body and rotary fixed bracket inboard, and the locking bar top is furnished with sheath.

During use, lock body and rotary fixed bracket are fixed on the corresponding cant beam on the vehicle frame with clamping plate respectively, locking bar is aimed at the socket of lock body, during locking locking bar is inserted in the lockhole, extract key, inserted in the breach at relative two back sides of locking bar by locking plate two blades because locking bar inserts lock body, and there is 5 ° the angle of sloping inwardly to make locking bar firmly locked, when unblanking, key inserted in the lock core rotate, lock core drives locking plate and rotates, the breach of leaf abscission locking bar, locking bar can be extracted, continue to extract because the location lock of locking bar end is stuck in the rotating shaft of runing rest, rotate up 90 ° along notch, the locking bar two ends is stretched out from fixed support lower end two openings, locking bar is fixed on the fixed support vertically downward, inwardly inserts in the socket that inserts lock body just again as long as locking bar is upwards extracted the back half-twist.

Detailed structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is the rotary vehicle beam-inserted lock of a pull bar structure principle chart;

Fig. 2 is the rotary vehicle beam-inserted lock of a pull bar construction profile;

Fig. 3 is the rotary vehicle beam-inserted lock of pull bar lock body inner structure figure.

Its structure is by Fig. 1, shown in 2,3,1 is lock body, 2 is locking bar, 3 is runing rest, and 4 is locking plate, as shown in Figure 3,10 is the lock core spring above the locking plate 4, on the fixed bolt hole, 11 is the locking plate spring, and 12 is fixed bolt hole, the purpose that lock body and locking plate are added with spring respectively is locking bar directly can be inserted locking when not needing key to insert, the purpose that leaves half little garden breach on the locking plate is that locking bar inserts conveniently, and locking plate is thrown off automatically, and 9 is lock core, the front is the key mouth, 8 is axis of rotation on runing rest 3, and 7 is the locking bar sheath, on lock body 1 and swivel mount 3 geometrical clamp 5 and 6 is housed respectively.Runing rest can be plastics and makes.The advantage of the utility model: simple in structure, easy to use, the pick-proof performance is good, is a kind of more perfect vehicle lock.
