Detailed Description

Example 1:

referring to fig. 1-9, a cabinet door lock comprises a main body 1, a lock cylinder 2, a spring 3 and a locking plate 4.

Be equipped with on main part 1 and hold cavity 11, hold cavity 11 and be for running through 1 whole settings of main part, hold the upper end of cavity 11 and be used for the lock opener to stretch into to holding cavity 11 in, realize unblanking and shutting function. An opening 12 is arranged at the lower end of the accommodating cavity 11, and the size of the opening 12 is smaller than that of the accommodating cavity 11, so that the spring 3 is sleeved on the lock cylinder 2, and the other end of the spring can be abutted against the side wall of the inner side of the opening 12, and the effect of fixing the spring 3 is achieved. The outer side of the main body 1 is provided with an external thread, so that the main body 1 can be conveniently installed on a cabinet door.

At least two limiting bosses 13 are arranged on the opening 12, a limiting gap 14 is formed between the two limiting bosses 13, and the limiting bosses 13 are specifically located in the radial direction of the opening 12, so that the size of the opening 12 is further reduced. In this embodiment, the number of the limiting bosses 13 is three, and a limiting notch 14 is formed between two adjacent limiting bosses 13, so that the number of the limiting notches 14 is two. The limit bosses 13 are not distributed in a circumferential array, so that the locating parts 15 are formed between the limit bosses 13 on two sides, and the locating parts 15 are arranged in an arc, wherein the arc length of the locating parts 15 is at least one third of the circumference length of the opening 12, but not more than one half of the circumference length of the opening 12. Here, the angle formed by the imaginary center lines of the two outer limiting projections 13 and the imaginary center line of the middle limiting projection 13 is 90 °.

Further, spacing boss 13 sets up for the halfpace type, and the top of halfpace is the concave arc face for the endwise slip between spacing boss 13 and the lock core 2 is more smooth and easy, reduces frictional resistance.

The whole cylindrical setting that is of lock core 2, its top is drive division 21, and the setting of drive division 21 can realize the drive effect through the ware of locknut that corresponds, and here drive division 21 can be the triangular prism setting.

A circular table portion 22 is arranged below the driving portion 21, and the circular table portion 22 is mainly used for sleeving the spring 3, so that the spring 3 is sleeved on the lock cylinder 2, one end of the spring abuts against the circular table portion 22, and the other end of the spring abuts against the inner side wall of the opening 12.

The below of drive division 21 is cylinder portion 23, is equipped with on the cylinder portion 23 and is the arch 24 and spacing protruding muscle 25 that the circumference array distributes, and arch 24 cooperates with spacing breach 14, realizes the radial fixation between lock core 2 and the main part 1, and arch 24 also is located the radial direction of cylinder portion 23, increases the radial dimension of cylinder portion 23. The limiting convex rib 25 is connected with two adjacent bulges 24. Two adjacent bulges 24 are connected through a limiting convex rib 25, so that the whole limiting structure is increased, the limiting stability is further ensured, and the limiting arc length after connection is at least one third of the whole perimeter of the opening 12. It should be noted here that the length of the arc of the positioning portion 15 is greater than the length of the connecting arc of the outermost side of two adjacent projections 24, so as to ensure that the lock cylinder 2 can pass through the opening 12, where the central angles of the two dimensions differ by 5 ° to 15 °.

The protrusion 24 is provided with a guiding surface 241 towards the side of the circular table portion 22, and the guiding surface 241 is arranged so that after the lock cylinder 2 is driven to rotate, the spring 3 is reset, and a guiding effect is achieved between the lock cylinder 2 and the opening 12.

The bottom end of the lock core 2 is arranged in a quadrangular shape. The bottom end of the lock cylinder 2 is arranged in a quadrangular shape, so that the lock cylinder 2 and the locking plate 4 are fixed more firmly and are not easy to slip. Be equipped with internal thread hole 26 on the bottom, fastener 5 passes locking plate 4 to be connected with internal thread hole 26, has realized the fastening effect between lock core 2 and the locking plate 4. It should be noted here that the protrusion 24 is located above the four corners of the quadrangular prism, i.e. the center line of the protrusion 24 coincides with the four corners of the quadrangular prism.

It is in the assembling process, overlaps earlier spring 3 on lock core 2, aims at location portion 15 and spacing protruding muscle 25 for both are in same axial direction (if unaligned unable realization assembly), stretch into lock core 2 this moment to holding in the cavity 11, make the bottom of lock core 2 stretch out from opening 12, then pass locking plate 4 through fastener 5 and fix with lock core 2, realize holistic assembly. The assembled cabinet door lock realizes radial locking because the bulge 24 is matched with the limiting notch 14, so that the lock cylinder 2 cannot rotate. When needing to rotate, through the cooperation of lock opener and drive division 21, press hard downwards for the whole axial motion of lock core, when cylinder portion 23 stretches out to opening 12 department, rotate the lock opener, make lock core 2 rotate, change another arch 24 and spacing breach 14 cooperation, thereby realize rotating the unblock effect.

Firstly, adopt protruding 24 and spacing breach 14 cooperation, realized the radial locking effect between lock core 2 and the main part 1, and the setting of spacing protruding muscle 25, make play the direction effect in the assembling process, and in the assembling process, wear out the back in the main part 1 when lock core 2, turned angle, can realize fixed effect, this moment because spacing protruding muscle 25 offsets with spacing boss 13, make lock core 2 lock in the axial, unable motion, this moment, the assembler carries out the installation of locking plate 4 fixed, and is very convenient, need not use too big power to press, and the situation that lock core 2 catapult can not take place yet, the assembly is simple also safe.

Example 2:

referring to fig. 10 to 11, the difference between embodiment 2 and embodiment 1 is that the cylindrical portion 23 is provided with guide ribs 27 arranged in a circumferential array, the guide ribs 27 are connected to the boss 24, and the guide ribs 27 are located on the side facing the circular table portion 22. The guide rib 27 further provides a guide effect during the reset.
