Description

Technical Field

[0001] The utility model relates to the technical field of buckles, in particular to a buckle with a locking structure. Background Art

[0002] A snap fastener is a mechanism used for embedding and connecting one part with another or for integral locking. It is usually used for connecting plastic parts, and its material is usually made of plastic material with a certain degree of flexibility.

[0003] Our company has recently developed a multifunctional handbag that can be fully unfolded when needed and can be folded together when not needed. Therefore, a buckle structure needs to be applied to the top of two adjacent extended cloths of the bag body. The existing buckles are generally composed of a male head and a female head. However, the length is fixed after the buckle is completed, so the distance between the two connected parts is also fixed. If the items to be loaded are large, the placement process will be more inconvenient and inconvenient to use. There is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, in this embodiment, a buckle with a locking structure includes multiple female heads 1 and a sub-head 2, and is characterized in that: two adjacent female heads 1 are installed with the same connecting assembly 4, and the connecting assembly 4 includes a rotating column 401 fixedly connected to a corner of the female head 1, and cylinders are arranged at both ends of the rotating column 401. A sliding sleeve at one end of the bottom of the rotating column 401 is provided with a receiving sleeve 402, and the receiving sleeve 402 is fixedly connected to the outer wall of the bottom of the other female head 1. A rotating sleeve at one end of the top of the rotating column 401 is provided with a limiting sleeve 403, and a plurality of bolts 404 are threadedly connected between the limiting sleeve 403 and the other female head 1.

[0023] Insert the bottom end of the rotating column 401 at one end of the other female head 1 into the receiving sleeve 402, then put the limiting sleeve 403 on one end of the top of the rotating column 401, and then use the bolt 404 to fix the limiting sleeve 403 on the top of the other female head 1, so that multiple female heads 1 can be installed to form a whole strip, and ensure that the adjacent multiple female heads 1 can be flipped and folded at will, so that the sub-head 2 can be connected to any female head 1 as needed, and the overall length of the connection between the sub-head 2 and the female head 1 can be adjusted at will as needed.

[0024] like Figure 3 and Figure 4 As shown, a clamping assembly 5 is installed outside the sub-head 2 , and the clamping assembly 5 is installed at one side of the sub-head 2 .

[0025] The clamping assembly 5 includes two extension rods 501 fixedly connected at the top and bottom of the outer wall of one side of the sub-head 2, and a positioning rod 502 is slidably inserted at one end of the two extension rods 501. A spring 504 is fixedly connected between the two positioning rods 502 and the two extension rods 501, and a clamping groove 503 is provided at the ends of the two positioning rods 502 that are close to each other.

[0026] A limiting groove 505 is formed on the top and bottom outer walls of the plurality of female connectors 1 , and the two positioning rods 502 can enter the two limiting grooves 505 respectively.

[0027] Insert one end of the sub-head 2 into the corresponding internal space of the female head 1, the extension rod 501 will first enter the interior of the female head 1, and the positioning rod 502 at one end of the extension rod 501 will move downward along the extension rod 501 under the squeezing of the corners of the female head 1. During this period, the spring 504 will also be driven to extend and lengthen. When one end of the positioning rod 502 moves to the position of the limiting groove 505, the spring 504 will drive the end of the positioning rod 502 with the card slot 503 to enter the limiting groove 505. At this time, the top of the positioning rod 502 will also fit with the inner wall of the limiting groove 505 to achieve a locking effect, thereby ensuring that the extension rod 501 cannot be withdrawn due to external force.

[0028] like Figure 4 As shown, the inner walls of one side of the plurality of limit grooves 505 are all provided with guide bevel grooves 506. If the sub-head 2 needs to be taken out, the sub-head 2 and the extension rod 501 are just pushed, and the positioning end of the positioning rod 502 will move along the guide bevel grooves 506, and then the positioning end of the positioning rod 502 will also enter the extension rod 501, and the extension rod 501 can also be easily moved out of the female head 1.

[0029] like Figure 1 and Figure 2 As shown, one side outer wall of the sub-head 2 and the other side outer wall of one of the female heads 1 are fixedly connected with a connecting frame 3, and the connection between the buckle and the package body can be achieved through the connecting frame 3.

[0030] like Figure 1 As shown, the sub-head 2 and the plurality of female heads 1 are all made of stainless steel, which ensures that the overall strength of the buckle is sufficient while not being easily corroded.

[0031] The utility model provides a buckle with a locking structure, and the specific working principle is as follows:

[0032] When the device is working, first use the connecting frame 3 to install a female head 1 and a sub-head 2 on the outer wall of the bag, then insert the bottom end of the rotating column 401 at one end of the other female head 1 into the receiving sleeve 402, then put the limiting sleeve 403 on one end of the top of the rotating column 401, and then use the bolt 404 to fix the limiting sleeve 403 on the top of another female head 1, so that multiple female heads 1 can be installed to form a whole strip, and ensure that the adjacent multiple female heads 1 can be flipped and folded at will, so that the sub-head 2 can be connected to any female head 1 according to needs, and then the overall length of the connection between the sub-head 2 and the female head 1 can be adjusted as needed, and then one end of the sub-head 2 is inserted into the corresponding internal space of the female head 1, and the extension rod 501 will first enter the inside of the female head 1, The positioning rod 502 at one end of the extension rod 501 will move downward along the extension rod 501 under the pressure of the corners of the female head 1. During this period, the spring 504 will also be driven to extend and lengthen. When one end of the positioning rod 502 moves to the position of the limiting groove 505, the spring 504 will drive the end of the positioning rod 502 with the card slot 503 to enter the limiting groove 505. At this time, the top of the positioning rod 502 will also fit with the inner wall of the limiting groove 505 to achieve a locking effect, thereby ensuring that the extension rod 501 cannot be withdrawn due to external force. If you need to take out the sub-head 2, just push the sub-head 2 and the extension rod 501, the positioning end of the positioning rod 502 will move along the guide inclined groove 506, and then the positioning end of the positioning rod 502 will also enter the extension rod 501, and the extension rod 501 can also be easily moved out of the female head 1.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
