Description

[Technical field]

[0001] The utility model relates to an elastic buckle. [Background Technology]

[0002] The buckle on the existing strap is usually an integral ring structure with a fixed shape. The width of the buckle is usually slightly larger than the width of the connecting end of the strap. The buckle is usually fixedly connected to the strap, and the strap and buckle of a set width are used on a set product. However, in some application scenarios, such as some binding and fixation during surgery or after surgery, different instruments sometimes require buckles of different widths to be used, or when an instrument with a buckle needs to be tied with straps of different sizes, due to the inappropriate size, it is often necessary to make do with it, or it takes time to modify it for use, which is not convenient.

[0003] The present invention is made based on the above situation. [Utility Model Content]

[0004] The purpose of the utility model is to address the deficiencies of the existing technology and to propose an elastic buckle. The utility model has a simple structure and the elastic buckle is easy to assemble and disassemble, thereby making it convenient to select different straps or elastic buckles for assembly and use on site.

[0005] The belt buckle of claim 1, wherein the first and second ends of the first and second half buckles are aligned and form a ring-shaped belt buckle, the first half buckle is provided with a channel inside the first half buckle, the channel is connected to one end of the first half buckle, and the second half buckle is provided with a shaft at one end. The shaft is inserted into the channel from one end of the first half buckle and can rotate in the channel and move up and down along the axial direction of the shaft. The second half buckle and the first half buckle are provided with a plug-in structure that is plugged in and connected together up and down on the other end. The channel is provided with an elastic member with one end fixed to the first half buckle and the other end connected to the shaft. The elastic member pulls the shaft to fix the second half buckle to the first half buckle. The length of the plug-in structure is less than the length of the shaft that can move up and down in the channel so that the plug-in structure can be disengaged when the second half buckle is pulled upward relative to the first half buckle, thereby allowing the second half buckle to rotate relative to the first half buckle with the shaft as the rotating axis.

[0006] In the elastic buckle as described above, the elastic member is an elastic cord.

[0007] In the elastic buckle as described above, one end of the elastic member is connected to a hollow pin for fixing it on the inner end of the channel, and the lower end of the shaft is provided with a hook connected to the other end of the elastic member.

[0008] In the elastic buckle as described above, a limiting ring is fixed to the first half of the buckle at the passage opening to prevent the shaft from escaping from the passage.

[0009] In the elastic buckle as described above, the plug-in structure includes a plug provided on one end of the second half buckle and a socket provided on one end of the first half buckle.

[0010] In the elastic buckle as described above, the head of the plug is provided with a chamfer.

[0011] Compared with the prior art, the present invention has the following advantages: the second half buckle is elastically fixed to the first half buckle by an elastic member, and the second half buckle can be pulled apart from the first half buckle by force, so that the plug-in structure is disengaged. The elastic buckle can be removed from the belt loop of the strap through the opening, and the elastic buckle can also be installed on the belt loop. After the plug-in structures of the second half buckle and the first half buckle are aligned, the external force is released, and under the action of the elastic member, the second half buckle and the first half buckle are reconnected and fixed together to form a ring-shaped buckle. Therefore, the strap and the elastic buckle can be used as independent components, and the same strap can be used with elastic buckles of different sizes, and the same elastic buckle can also be used with straps of different sizes, making it easy to select the elastic buckle or strap of the appropriate size according to the use requirements, and can be conveniently assembled and used on the use site.

[0017] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0018] like Figure 1-4As shown, an elastic buckle comprises a first half buckle 1 and a second half buckle 2, the two ends of the first half buckle 1 and the second half buckle 2 are aligned respectively to form a ring-shaped buckle, the first half buckle 1 is provided with a channel 10 inside, the channel 10 is communicated with one end of the first half buckle 1, one end of the second half buckle 2 is provided with a shaft 21, the shaft 21 is inserted into the channel 10 from one end of the first half buckle 1 and can rotate in the channel 10 and move up and down along the axial direction of the shaft 21, the second half buckle 2 and the first half buckle 1 are provided with a vertical plug-in connection on the other end The plug-in structure is a plug-in structure, and an elastic member 3 is provided in the channel 10, one end of which is fixed to the first half buckle 1 and the other end is connected to the shaft 21. The elastic member 3 pulls the shaft 21 to fix the second half buckle 2 on the first half buckle 1. The length of the plug-in structure is less than the length of the shaft 21 that moves up and down in the channel 10 so that the plug-in structure can be disengaged when the second half buckle 2 is pulled upward relative to the first half buckle 1, so that the second half buckle 2 can rotate relative to the first half buckle 1 with the shaft 21 as the rotating axis, so as to form an opening 20 that is convenient for disassembling and assembling the elastic buckle.

[0019] When the elastic buckle is in use, Figure 3 As shown, the second half buckle 2 is pulled away from the first half buckle 1 with force to disengage the plug-in structure. The elastic buckle can be removed from the belt loop of the strap through the opening 20, and the elastic buckle can also be installed on the belt loop. After aligning the plug-in structures of the second half buckle 2 and the first half buckle 1, release the external force. Under the action of the elastic member 3, the second half buckle 2 and the first half buckle 1 are reconnected and fixed together to form a ring-shaped buckle, as shown in FIG. Figure 2 shown.

[0020] Therefore, the straps and elastic buckles can be used as independent components. The same strap can be used with elastic buckles of different sizes, and the same elastic buckle can also be used with straps of different sizes. This makes it easy to select the elastic buckle or strap of appropriate size according to usage requirements, and can be easily assembled and used at the site of use.

[0021] Preferably, the plug-in structure includes a plug 23 provided on one end of the second half buckle 2 and a socket 11 provided on one end of the first half buckle 1 .

[0022] Preferably, a chamfer 24 is provided on the head of the plug 23 to facilitate insertion of the plug 23 into the socket 11 .

[0023] Preferably, the elastic member 3 is an elastic rope, which is convenient for installation in the U-shaped channel 10 .

[0024] Preferably, one end of the elastic member 3 is connected to a hollow pin 4 for fixing it to the inner end of the channel 10, and the lower end of the shaft 21 is provided with a hook 22 connected to the other end of the elastic member 3, which is convenient for production and assembly.

[0025] Preferably, a limiting ring 5 is fixed at the opening of the channel 10 of the first half buckle 1 to prevent the shaft 21 from escaping from the channel 10 , thereby preventing the shaft 21 from escaping from the channel 10 .
