As shown in fig. 13, a protruding cylinder 26 is disposed on the inner top surface of the housing of the lock body 2, a cylinder hole 27 for inserting the protruding column 25 of the connecting band 4 is opened in the protruding cylinder 26, and the protruding column 25 of the connecting band 4 is inserted into the cylinder hole 27 of the lock body 2 with tight fit. Generally, it suffices that the projecting column 25, the projecting cylinder 26, and the cylinder hole 27 are all provided in 2. The connecting band 4 chooses the better plastics preparation of elasticity for use, has good pliability simultaneously, guarantees can not break in the design service life, like this, and usable its elasticity makes lock body 2 automatic springing open when unblanking. The connecting band 4 should be made with enough length, and the user can cut the connecting band 4 to a proper length as required.
As shown in fig. 18, 19, 20 and 21, the fixing base 3 includes a base 28 and a cover block 29, wherein the base 28 is provided with a cover block accommodating recess 30 for accommodating the cover block 29, and the base 28 is also generally in a shape of a top housing; a downward extending buckling column 31 is arranged below the cover block 29, and a pin shaft 32 is arranged at one end of the cover block 29, which faces the lock body 2, and extends towards two sides of the cover block; a cover block accommodating pit 30 of the base 28 is provided with a buckling hole 33 for buckling the extending buckling column 31, and two sides of the cover block accommodating pit 30 of the base 28 facing one end of the lock body 2 are provided with corresponding pin shaft holes 34 for inserting and rotating the pin shafts 32; the free end 24 of the connecting band 4 is located in a cover block accommodating pit 30 of a base 28 of the fixed seat 3 and is covered by a cover block 29, and a buckling column 31 extending from the lower side of the cover block 29 penetrates through a corresponding position of the hole 22 of the connecting band 4 to fix the connecting band.
As shown in fig. 2, the lock case bottom cover 35 and the fixing base bottom cover 36 are respectively disposed at the bottom of the lock case 1 and the fixing base 3. For the convenience of installation, the bottom surfaces of the lock shell bottom cover 35 and the fixing seat bottom cover 36 can be respectively pasted with adhesive tapes with double surfaces glued. The double-sided adhesive tape produced by 3M company and having high quality and durability can be selected. When the lock is installed, the protective film on the double-sided adhesive tape is torn, and the lock for preventing the child from opening can be stuck and installed on a target appliance such as a cabinet door.
As shown in fig. 22, 23, 24 and 25, a plurality of protruding columns 25 are respectively disposed on the upper surfaces of the lock case bottom cover 35 and the fixing base bottom cover 36, a plurality of protruding cylinders 26 are disposed on the inner top surfaces of the lock case 1 and the fixing base 3, a cylinder hole 27 for inserting the protruding column 25 of the connecting band 4 is opened in each protruding cylinder 26, and the protruding column 25 of the connecting band 4 is tightly inserted into the cylinder hole 27 of the lock body 2. If the tight fit is not sufficiently secure, further glue bonding or ultrasonic welding may be used.
As shown in fig. 12, a limiting rib 37 is provided on the lock body 2. As shown in fig. 16 and 17, 2 limiting ribs 37 are circumferentially arranged on the inner wall of the knob member 20 at 90-degree intervals. During assembly, the limiting ribs 37 of the lock body 2 are positioned between the 2 limiting ribs 37 on the inner wall of the knob piece 20, so that the knob piece 20 and the small lock cylinder 13 can only swing within the range of 90 degrees. As shown in fig. 14 and 15, arc-shaped ribs 38 are provided on both sides in the longitudinal direction of the locking portion 19 of the key cylinder 13. Matching with the arc convex ribs 38 at two sides of the long direction of the clamping part 19 of the small lock core 13, as shown in fig. 13, 2 pairs of damping ribs 39 are symmetrically arranged in the shell of the lock body 2; as shown in fig. 10 and 11, 2 pairs of damping ribs 39 are also provided symmetrically on the corresponding surface of the slide fastener 7. The contact end portion of each of the damper ribs 39 is also arc-shaped. When the small lock core 13 is in the open position, the arc convex rib 38 is clamped between 2 pairs of damping ribs 39 symmetrically arranged in the shell of the lock body 2; when the small lock cylinder 13 is in the locked position, the arc-shaped ribs 38 are clamped between 2 pairs of damping ribs 39 of the slide fastener 7. Thus, when the user operates the rotary knob member 20, the user has obvious hand feeling when rotating the small lock cylinder 13 to the opening position or the locking position.
The lockset for preventing children from opening is particularly suitable for being arranged between a cabinet door, a refrigerator door and the side wall of the cabinet door, and when the lockset is locked, as shown in figure 4, the small lock cylinder 13 is in an opening position, and the lock body 2 is pressed into the accommodating pit 5 of the lock shell 1 by force. Because the back of the barb of the buckle 8 is the slope 41, the lock body 2 overcomes the elasticity of the compression spring 9 and slides downwards along the slope 41 until the barb of the buckle 8 is buckled into the lock body side notch 11 of the lock body 2 to complete locking, and the lock body is kept locked under the elasticity of the compression spring 9. When unlocking, a user only needs to rotate the knob piece 20 to enable the small lock cylinder 13 to be located at the opening position, and then presses the sliding fasteners 7 on the two sides by overcoming the elasticity of the compression spring 9, namely, the sliding parts 16 of the sliding fasteners 7 exposed on the two sides are pressed inwards until the buckles 8 are separated from the lock body side notches 11 of the lock body 2, and the lock body 2 can be automatically ejected out due to the good flexibility of the connecting belt 4 to complete unlocking.
The lock unlocking method has the advantages that the lock unlocked by the child can be prevented from being unlocked only by two continuous actions, the unlocking operation is very convenient for people who know the unlocking method of the lock, the unlocking operation can be conveniently finished by one hand, and the locking and unlocking operation is very convenient; however, for the children who do not know the unlocking method of the lock and have insufficient intelligence, the lock can be hardly unlocked no matter how the children press the lock in disorder, and the probability that the children press the lock in disorder to unlock the lock is almost zero.
