Specific embodiment

Further details of non-limitative illustration is made to the utility model with reference to the accompanying drawings and examples.

As Fig. 1 and Fig. 2 jointly shown in, the combination lock of the utility model includes lock 1 and the tapered end for cooperating with lock 1 Component, lock head component include the lock core 2 and locking closure 3 of clamping connection.

As Fig. 3, Fig. 4 and Fig. 5 jointly shown in, wherein lock 1 includes pedestal 11, and pedestal 11 is provided with pedestal through-hole 13, seat The inner wall of body through-hole 13 is provided with lock protrusion 131, and lock protrusion 131 is the internal projecting ring for being formed in 13 inner wall of pedestal through-hole, interior The section of bulge loop is arc-shaped, and preferred embodiment is arc-shaped；The side of pedestal 11 is provided with latch hook 12, latch hook 12 is logical positioned at pedestal Except hole 13.

Wherein, latch hook 12 includes latch hook arm 121 and the latch hook hook portion 122 for being set to 121 one end of latch hook arm, latch hook hook Portion 122 is provided with locking face 1221 and inclined guide surface 1222, and the other end of latch hook arm 121 is fixedly connected with pedestal 11.Its In, locking face 1221 is consistent with 11 setting direction of pedestal, all vertical with latch hook arm 121.

Wherein, stronger reliable to install lock 1, latch hook 12 circumferentially have it is multiple, preferred embodiment be it is uniformly distributed, it is more A latch hook hook portion 122 is radially in radial outward.Obviously, it is not limited to radially, can also be in external radiation with Off-Radial Shape.

As Fig. 6, Fig. 7, Fig. 8 and Fig. 9 jointly shown in, wherein lock core 2 include partition 21, be fixedly installed on 21 side of partition Lock auxiliary section 22 for cooperating with lock through-hole 13 is fixedly installed on lock of 21 other side of partition for cooperating with locking closure 3 Lid auxiliary section 23.

Wherein, the end outer wall of lock auxiliary section 22 is provided with the lock core protrusion 221 with 131 cooperation of lock protrusion, lock core Protrusion 221 is the outer bulge loop for being formed in lock auxiliary section outer wall, and the section of outer bulge loop is arc-shaped, and preferred embodiment is arc-shaped.

Wherein, locking closure auxiliary section 23 includes multiple claws 231 circumferentially, and preferred embodiment is uniformly distributed, multiple claws 231 radially in radial outward, it is clear that it is not limited to radially, it can also be with Off-Radial in radial outward.Further Ground, in order to more swimmingly be clamped with locking closure 3, the outer end face of claw 231 is designed as curved guiding surface 2311.

As Figure 10, Figure 11 and Figure 12 jointly shown in, wherein locking closure 3 include lid 31, the inner circumferential of lid 31, which is provided with, to be used for The snap ring 32 being clamped with the claw 231 of lock core 2, the open-position-side of lid 31, which is located at except snap ring 32, is provided with lid seam allowance 33.Into One step, in order to more swimmingly be clamped with claw 231, the inner ring surface of snap ring 32 is designed as the curved guiding surface 2311 with claw 231 The guiding conical surface 321 of cooperation.

As Figure 13 and Figure 14 jointly shown in, wherein guiding the conical surface 321 miner diameter end radial dimension be less than curved guiding surface 2311 Bigger diameter end radial dimension, after lock core 2 and locking closure 3 are clamped, under locking state, locking closure 3 and lock core 2 is avoided to be detached from.

Wherein, in the present embodiment, lock 1, lock core 2, locking closure 3 are all one-time formed mouldings, and structure is simple, are easy to make It makes, it is at low cost.

Shown in Fig. 1 and Fig. 2, for being applied to the packing containers such as cabinet, the locking and unlocking of the utility model combination lock Mode is as follows:

The packing containers such as well known cabinet include wall box and case lid, are provided on side wall, that is, inner panel 5 of cabinet interior Plate installation through-hole is provided with cover board installation through-hole on the corresponding position of case lid, that is, cover board 4；Lock 1 is installed in inner panel 5 When plate installation through-hole, by means of 122 inclined guide surface 1222 of latch hook hook portion of latch hook 12, multiple latch hooks 12 are collapsed towards center, Expansion is resetted after passing through inner panel installation through-hole, the locking face 1221 of latch hook hook portion 122 is posted by the medial surface of inner panel 5, seat Body 11 is posted by the lateral surface of inner panel 5, conveniently and efficiently realizes lock 1 and the installation of inner panel 5 is fixed, and firmly installing can It leans on, even if being used for multiple times, lock 1 will not be detached from inner panel 5；When needing to lock cover board 4 and inner panel 5, lock head component is pacified The pedestal through-hole 13 of lock 1 is inserted into cover board installation through-hole loaded on cover board 4, the lock auxiliary section 22 of lock core 2, for example by external force Finger squeezes or pressing locking closure 3, so that lock core protrusion 221 is crossed lock protrusion 131 and is limited by lock protrusion 131, prevents lock Core 2 retracts, and conveniently and efficiently realizes the locking of cover board 4 Yu 5 two components of inner panel, and reliable lock；It is right when needing to unlock Cover board 4 exerts a force, for example, being detached from lock core protrusion 221 with lock protrusion 131, lock core 2 returns with the edge 41 of the outside flip plate 4 of hand It moves back, continuation is lifted outward, and lock auxiliary section 22 is detached from pedestal through-hole 13, conveniently and efficiently realizes unlocking.Due to locking or unlocking In the process, lock 1, lock core 2, locking closure 3 will not be destroyed, thus can be used for multiple times, and be all muptiple-use using part.

In conclusion the combination lock of the utility model uses the cooperation of 3 three lock 1, lock core 2 and locking closure parts, quickly The locking and unlocking between two components are realized, structure is simple, and it is easy to use, and can be used for multiple times, it is at low cost.
