Abstract

The utility model provides a box lock; wherein a spring cavity is provided in the key cylinder hole of the lock body; a torsion spring which is respectively connected with the lock body and the key cylinder at the two ends is provided in the spring cavity; a sloping side is provided on the top of a lock hook which is connected with the tail of the key cylinder. When in use, the lock body is arranged on the box wall; a cylindrical lock pin is arranged on the box cover. Under general conditions, the torsion spring keeps the lock hook in the vertical and upward position. If the box cover is pressed, the lock pin presses the lock hook and the lock hook turns clockwise, which enable the box cover moves downward continuously until covering the lock; after the box cover covers the lock, the lock hook resets under the torsion spring action and buttons up the lock pin, then the box cover can not be opened and the box is automatically closed. When being unlocked, the key turns the key cylinder clockwise, the lock hook moves away the lock pin and the box cover is opened. When the box is locked by the lock, the key is not needed, which offers much convenience for the user.

Description

Case is with locking

Technical field

The utility model relates to a kind of lock, and particularly a kind of case of motorcycle and electric bicycle luggage case that is mainly used in is with locking.

Background technology

Motorcycle on the existing market, electric bicycle case comprise lock body and the lock core that cooperatively interacts with lock (baggage compartment lock), and lock core is enclosed within the lock core hole of lock body, and its tail end leans out lock core hole, and is fixedly connected with lock hook, and described lock hook is for walking crosswise straight hook.Split out lock hook when mounted, screw out nut and refill cartonning hole inward turning jack panel, fixedly lock body and lock hook are installed translot lock hook link plate again on the case lid, with key direction rotation left lock hook are slipped in the translot hanging plate slot and catch on up and down, could pin.The defective of this lock is that switch-box must be with key to the rotation of different direction (locking one along opening), and as without manual key, this lock is with being in the state (because only relevant could transfer to key) of pass for a long time, and is very inconvenient during use.

The utility model content

For overcoming the above-mentioned technological deficiency of prior art, the utility model provides a kind of and has closed automatically, the automatically reset case of lock hook lock, uses this lock, does not need to use key during the lock case, as long as case lid is depressed, just can build case lid, and automatically with the chest locking.

The technical scheme that the utility model overcomes the above-mentioned technological deficiency of prior art is: case comprises lock body and the lock core that cooperatively interacts with lock, lock core is enclosed within the lock core hole of lock body, its tail end leans out lock core hole, and be fixedly connected with lock hook, be provided with spring cavity in the described lock core hole, be provided with the torsion spring that two ends are connected with lock core with lock body respectively in this spring cavity, described lock hook top is provided with hypotenuse.

Using method of the present utility model and operating principle are: lock body is installed on the tank wall, cylindrical lock pin is installed on the case lid, torsion spring makes lock hook be in vertically upward position under the normality, when pressing down case lid, lock pin on the case lid touches the hypotenuse at lock hook top earlier, pressing this hypotenuse clockwise rotates lock hook, case lid is continued to move down until building, and case lid is built the back lock pin and is in lock hook and colludes the corresponding position of groove, and lock hook is multiple under the effect of torsion spring should, again can arrive position vertically upward, it colludes groove and is buckled on the lock pin, blocks lock pin and makes it and can not move up, and chest just is in locking states like this, case lid can not be opened, use key to clockwise rotate lock core (rotational angle often can be made as 90 °) when unblanking, drive lock hook and break away from lock pin, at this moment just can open case lid, after unclamping or transfering to key, torsion spring can make lock hook reset again.

Because the torsion spring that the utility model being provided with is in vertical position lock hook automatically, and the lock hook top is set to the inclined-plane, case lid can be depressed to be built, build the back lock hook and automatically lock pin is fastened, therefore the locking casing does not only hinder the top box lid, as long as build case lid, chest just can automatic blocking, does not need to use key during the lock case, is very easy to use.

Description of drawings

Fig. 1 is the case side-looking structural representation of locking that the utility model provides;

Fig. 2 be the case that provides of the utility model with lock main look surface structure and with the schematic diagram of lock pin matching relationship.

The specific embodiment

Referring to Fig. 1 and Fig. 2, the case that the utility model provides comprises lock body 2 and the lock core 4 that cooperatively interacts with lock, lock core 4 is enclosed within the lock core hole of lock body 2, and its tail end leans out lock core hole, and is fixedly connected with lock hook 1, be provided with spring cavity in the described lock core hole, be provided with the torsion spring 3 that two ends are connected with lock core 4 with lock body 2 respectively in this spring cavity, described lock hook top is provided with hypotenuse 7, and described lock hook 1 extends vertically upward under the normality, its main part is positioned at a side of center line 9, and it colludes the groove middle part and is positioned on the center line 9.

The described groove edge 6 that colludes generally can curved shape.

Described lock body afterbody can be provided with upwardly extending backplate 5, and this backplate 5 is positioned at the center line opposite side relative with lock hook under the normality, and when the chest locking, these backplate 5 retainings can not move lock pin 8 on lock pin 8 next doors.

The described center line of this manual and claims is meant the perpendicular bisector of lock body and lock core, so-called " on ", D score, " clockwise ", " counterclockwise ", " vertically " etc. only are for the facility on describing to the statement of direction, in order to represent the relativeness of each parts, do not constitute restriction to the utility model specific embodiment.

The case that the utility model provides also can be used for other chests, even be used for other any suitable places with locking the luggage case that can be used for motorcycle and electric bicycle.This manual to install and the description of mode of occupation just to being convenient to understanding, do not constitute restriction to installation of the present utility model and mode of occupation.

The embodiment of lock body and lock core and operating principle can adopt prior art or other possible technology of any suitable in the utility model.
