Description

Anti-shedding buckle structure

This creation is a kind of buckle-proof structure that prevents the falling off, which makes the buckle structure of the wrist strap easy and fast, and prevents the accidental fall off.

It is worn on the wrist as a device for transmitting signals, such as an electronic care device, which requires a wrist strap to be worn on the wrist, and a wrist strap that requires a buckle to fasten the ends of the wrist strap. There are two ways for the buckle of the conventional one: one is: the button body has a button hole at one end and the other end buckle column, and the buckle column can be inserted into the button hole to form a blocking and buckle effect. The other is: one end of the belt body is provided with a buckle hole, and the other end is provided with a protrusion seat, the protrusion seat has a screw hole, the protrusion seat can be inserted into the buckle hole, and then screwed to the screw hole to form a locking effect; the above-mentioned conventional manner In fact, there are the following shortcomings:

(1) The buckle-fastening can be easily disassembled without using a tool. Therefore, the user or the unscrupulous attempter can be easily opened, and the user cannot be kept worn.

(2) Although the screw locker needs to be opened with a screwdriver, the screwdriver is a tool that is extremely easy to obtain, so it can be easily opened.

(3) Because the screw locker has no other anti-shedding safety structure, it will loosen due to the vibration during use, causing the user to be mistakenly removed.

The present invention is to improve the above-mentioned shortcomings. The main technology and purpose are as follows: the two ends of the belt body are arranged as upper buckle pieces, and the bottom fastening piece is matched with bolts, and the upper buckle piece is provided with a groove and a positioning hole. The bolt is provided with an integrated turntable. The bottom surface of the turntable is provided with a spring, a hoop seat and a closing piece. The hoop seat is provided with a plurality of positioning buckles having a one-way inclined surface, and the positioning buckle can be inserted into the positioning hole of the upper buckle piece, or The positioning hole is removed; by the above structure, the user can fasten the two ends of the belt by rotating the rotary bolt with a finger, and the spring must have the effect of preventing the loosening of the bolt, in particular, it is necessary to use a special tool with magnetic attraction. Open the bolts to ensure the correct function of the belt.

Please refer to the first, second, third and fourth figures. The first body of the belt body 1 has a fastening hole 2 and 3, and the bottom surface of the belt body 1 is provided with a bottom fastening piece 14 , and the upper surface of the belt body 1 is provided with an upper fastening piece 10 . The bottom buckle piece 14 is provided with a boss 15 having a screw hole 16 , and the protrusion 15 is passed through the button hole 2 , 3 of the belt body 1 and the through hole 13 of the upper buckle piece 10 , and the upper buckle piece 10 is provided with the groove 11 . The bottom of the groove 11 is provided with a plurality of positioning holes 12, and a bolt 23 having a turntable 20 is screwed to the screw hole 16 of the boss 15 of the bottom buckle piece 14. The upper end surface of the turntable 20 is rough. The surface of the turntable 20 is provided with a ring groove 24 for the assembly spring 33, and a bottom end of the spring 33 is provided with a ring seat 30. The bottom surface of the ring seat 30 is provided with a plurality of positioning buckles 31, and each positioning The buckle 31 is provided with a unidirectional inclined surface 32. Further, a closing piece 40 is provided to close the iron ring seat 30 and the spring 33. The closing piece 40 is provided with a through hole 41 for the positioning buckle 31 of the iron ring seat 30 to pass through. The positioning buckle 31 is provided. The positioning hole 12 of the upper fastening piece 10 can be inserted, and the groove 11 of the upper fastening piece 10 can accommodate the turntable 20 of the bolt 23; further, a tool 50 is provided for the loose bolt 23 to open the two ends of the belt body 1, the tool 50 Set with magnetic rod 51, magnetic rod 51 Two bumps 52 corresponding to the bottom end of the bolt 23 of the turntable 20 two grooves 21, 52 formed bumps 21 can be engaged with the recess.

According to the above structure, the role and effect of this creation are described in detail as follows:

First, the finger locks and buckles:

Referring to the second figure, the turntable 20 of the bolt 23 is rotated by the finger 4, because the upper end surface of the turntable 20 has a rough surface 22 to increase the frictional force to rotate the turntable 20, and the positioning buckle 31 of the hoop seat 30 is provided. The one-way inclined surface 32 has the effect of forming a "one-way tooth", so that the positioning buckle 31 floats above the positioning hole 12 of the upper fastening piece 10, and is not inserted into the positioning hole 12, so that the turntable 20 and its bolt 23 can be rotated. The bolt 23 is locked to the screw hole 16 of the boss 15 of the bottom cleat 14 , that is, the two ends of the strap body 1 are fastened; as can be seen from the above description, the present invention can be completed with only the finger 4, Tools are needed for ease of use, simplicity, and speed.

Second, prevent accidental shedding:

Referring to the third figure, when the fastening is completed, the positioning buckles 31 of the iron ring seat 30 are inserted into the upper fastening piece. In the positioning hole 12 of the 10, if the rotating wheel 20 or the loose bolt 23 is reversely rotated by the finger 4 or the general tool, the positioning buckle 31 cannot be blocked by the "vertical angle" on the other side of the one-way inclined surface 32 of the positioning buckle 31. The positioning hole 12 is withdrawn and cannot be rotated. Moreover, the spring 33 is elastically pressed against the ring seat 30, and the positioning buckle 31 can be prevented from jumping out of the positioning hole 12, that is, the bolt 23 can be prevented from loosening, thereby preventing the false separation.

Third, the special tool 50 opens and closes:

Referring to the fourth figure, the tool 50 having the magnetic rod 51 is used to fit the two protrusions 52 of the magnetic rod 51 to the two grooves 21 of the turntable 20. The magnetic force of the magnetic rod 51 can suck the ring seat 30, so that The hoop seat 30 and its positioning buckle 31 are raised, and the positioning buckle 31 can be disengaged from the positioning hole 12 of the upper cleat 10, so that the turntable 20 and its bolt 23 can be rotated, that is, the bolt 23 can be loosened to allow the two strips 1 to be both ends Open; as can be seen from the above description, the present invention uses a general tool without magnetic attraction, and the bolt 23 cannot be rotated, thereby preventing the effect of being improperly opened.

In summary, the structure of this creation does have excellent practical value and enhanced efficiency. It is in line with the provisions of the Patent Law, so please grant a patent.
