Abstract

The utility model relates to a beam padlock which comprises a lock body, a lock cylinder and a lock cylinder hole, wherein the lock cylinder hole is formed at the lower end of the lock body and horizontally penetrates through the lock body, the lock cylinder is installed in the lock cylinder hole, one end of the lock cylinder is a key insertion end, a torsion spring is arranged at the other end of the lock cylinder in a sleeved mode along the axial direction, one torsion end of the torsion spring is limited on the lock cylinder, the other torsion end of the torsion spring is limited on a hole wall of the lock cylinder hole, a plugging block is used for plugging the lock cylinder hole at the outer end of the torsion spring, and the material of the plugging block is the same with the material of the lock body. A reset spring at the lower end of the lock cylinder of an existing beam padlock is replaced by a torsion spring structure, and the torsion spring is arranged at one end of the lock cylinder in the sleeved mode along the axial direction, the lock cylinder hole is horizontally communicated to facilitate installation of the torsion spring, and the beam padlock has the advantages of being reliable in lock cylinder reset, simple in reset structure, convenient to process, capable of ensuring that the surface of the lock body is artistic and the like.

Description

A kind of crossbeam padlock

Technical field:

The utility model relates to lockset, particularly a kind of crossbeam padlock.

Background technology:

The structure of existing crossbeam padlock as depicted in figs. 1 and 2, it mainly comprises lock body 1, lock bridge 2, lock core 3 and interlock assembly 4, lock core 3 is arranged in the lock core hole 5 of lock body 1 lower end, when unblanking, realize opening by the sealed groove that key 6 rotational lock cores 3 make interlock assembly 4 break away from lock bridge 2, after unblanking, in order to make lock core 3 reset to initial position, lock core 3 lower ends are provided with two and support the back-moving spring 7 that cooperates with it, two back-moving springs 7 be installed in respectively two upwards offered by lock body 1 bottom surface and with spring storage tank 8 that lock core hole 5 communicates in, the bottom shutoff of spring storage tank 8 has the material spring limited block 9 consistent with lock body.There is following shortcoming in this structure: (1) is because the lock body bottom surface is arcwall face, so the difficulty of processed springs storage tank is larger on arcwall face; Can stay in the lock body bottom surface obvious shutoff vestige during (2) owing to shutoff spring limited block, and the arcwall face structure of lock body bottom surface causes also this shutoff vestige to be not easy to the processing elimination, causes the not attractive in appearance of surface of lock body; (3) the bottom repeated action of back-moving spring causes the spring limited block to occur coming off on the spring limited block easily, and causes back-moving spring to be run out in the spring storage tank, and then affects resetting of lock core.

The utility model content:

Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of lock core to reset reliably, and resetting structure is simple, easy to process, and can guarantee the crossbeam padlock of surface of lock body aesthetic property.

Goal of the invention of the present utility model realizes by following technical scheme:

A kind of crossbeam padlock, comprise lock body, lock core, lock core hole, described lock core hole is arranged on lock body lower end and lateral direction penetrating in described lock body, described lock core is installed in the lock core hole, described lock core one end is the key insertion end, and the other end axially is set with a torque spring, this torque spring wherein one reverse the end be limited on the lock core, another reverses end and is limited on the hole wall of lock core hole, and described lock core hole has the material plugging block consistent with lock body in the shutoff of torque spring outer end.

Be provided with one on the described lock core and be used for the axially round boss of suit torque spring, offer a draw-in groove on the described round boss, what be used for limiting described torque spring wherein one reverses end, offers a bayonet socket on the hole wall of described lock core hole, and another that is used for limiting described torque spring reverses end.

As mentioned above, it is the torque spring structure that the utility model changes the existing back-moving spring that is arranged on the lock core lower end, and it axially is sleeved on lock core one end, also lock core hole is laterally got through so that the installation of torque spring simultaneously, therefore have following advantage with respect to prior art: 1, need not offer the back-moving spring storage tank in the lower arcuate surface of lock body, corresponding, only need laterally be opened the side surface of lock core hole self-locking body and get final product, and the plane structure of lock body side surface more is conducive to the processing of position, hole; 2, the shutoff vestige of leaving over when torque spring outer end shutoff lock core hole also because be the lock body side that is created in plane structure, thereby can be eliminated its processing very easily, guarantees the aesthetic property of surface of lock body; 3, torque spring does not act on the plugging block, but limits and act on the hole wall of lock core and lock core hole, thereby can not cause coming off of plugging block, more the phenomenon that torque spring is run out of can not occur, and then guarantee the reliability that lock core resets.

Fig. 2 is the cross-sectional schematic of A-A among Fig. 1.

Fig. 3 is the structural representation of the utility model crossbeam padlock.

Fig. 4 is the side direction scheme of installation of torque spring among Fig. 3.

The specific embodiment:

As shown in Figure 3 and Figure 4, as a kind of embodiment of the present utility model, this crossbeam padlock comprises lock body 1, lock core 2, lock core hole 3.Lock core hole 3 is arranged on lock body 1 lower end and lateral direction penetrating in lock body 1, and lock core 2 is installed in the lock core hole 3.Lock core 2 one ends are the key insertion end, the other end axially is set with a torque spring 4, wherein one the reversing end and 41 be limited on the lock core 2 of this torque spring 4, another reverses end 42 and is limited on the hole wall of lock core hole 3, lock core hole 3 has the consistent plugging block 5 of a material and lock body 1 in torque spring 4 outer end shutoff, plugging block 5 just is used for the open-ended of sealing lock core hole 3, torque spring 4 does not act on this plugging block 5, but utilize lock core 2 to hold power with respect to the rotation of the hole wall of lock core hole 3, and release strength makes lock core 2 reset to initial position when lock core 2 turns to lockset position of coupler.

More specifically, be provided with one on the lock core 2 and be used for the axially round boss 21 of suit torque spring 4, offer a draw-in groove 211 on the round boss 21, what be used for restriction torque spring 4 wherein one reverses end 41, offer a bayonet socket 31 on the hole wall of lock core hole 3, another that is used for restriction torque spring 4 reverses end 42.

Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that does not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
