Description

Technical Field

[0001] The utility model relates to the technical field of elastic bands, in particular to a combined elastic band. Background Art

[0002] An elastic band is an elastic strip, usually made of rubber and textile materials. Due to its excellent elasticity and adaptability, it has been widely used in the clothing field. Currently, combined elastic bands with buckle structures are relatively common, and most of these elastic bands are used to fix clothes;

[0003] When the existing combined elastic band is in use, the buckle mechanism on it usually only has one fixed position. Since the elastic band generally fits the user's body and is stretched adaptively according to the actual stretching length, however, when the elastic band is overstretched, it will exert a certain pressure on the user's body, thus affecting the user's comfort. Therefore, to solve this problem, designing a combined elastic band is what we need to consider. Content of the Utility Model

In view of the use problem, by inserting two limiting blocks into the corresponding limiting through grooves, the connection between the first connecting piece and the second connecting piece can be realized, and the comfort of using the elastic band body can be improved by adjusting the positions of the limiting blocks. At the same time, the two limiting blocks can be pushed out by pressing the two pressing blocks, so as to realize convenient disconnection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Limiting blocks are fixedly connected to the opposite sides of the two sliding blocks, and the opposite sides of the two limiting blocks penetrate through the second rectangular cavity and extend to the outside.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figures 1-4 , a combined elastic band, including an elastic band body 1. A first connecting piece 2 is fixedly connected to the left side of the elastic band body 1, and a second connecting piece 3 is fixedly connected to the right side of the elastic band body 1. A rectangular inner groove 4 is opened on the left side of the first connecting piece 2. Two first rectangular inner cavities 5 are symmetrically opened in the first connecting piece 2. A plurality of limiting through grooves 6 are opened between the front and rear inner walls of the rectangular inner groove 4 and the two first rectangular inner cavities 5. A rectangular clamping block 11 is fixedly connected to the right side of the second connecting piece 3. The rectangular clamping block 11 cooperates with the rectangular inner groove 4. By inserting the rectangular clamping block 11 into the rectangular inner groove 4, pre-positioning before connecting the first connecting piece 2 and the second connecting piece 3 can be realized. A second rectangular inner cavity 12 is opened in the rectangular clamping block 11;

[0021] Among them, a release component is further included. The release component includes two first connecting plates 7 respectively arranged in the two first rectangular inner cavities 5. Both of the two first connecting plates 7 are slidably connected to the inner walls of the corresponding first rectangular inner cavities 5. A plurality of release blocks 8 are fixedly connected to the opposite sides of the two first connecting plates 7. Each release block 8 is slidably connected to the inner wall of the corresponding limiting through groove 6. The opposite sides of the two first connecting plates 7 and the inner walls of the corresponding first rectangular inner cavities 5 are elastically connected by two first springs 9. The first spring 9 can ensure the reset of the first connecting plate 7 after moving. Pressing blocks 10 are fixedly connected to the opposite sides of the two first connecting plates 7. The opposite sides of the two pressing blocks 10 penetrate through the corresponding first rectangular inner cavities 5 and extend to the outside;

[0022] Among them, a limiting component is further included. The limiting component is used to connect the second connecting piece 3 and the first connecting piece 2. The limiting component includes two sliding blocks 13 arranged in the second rectangular inner cavity 12. Both of the two sliding blocks 13 are slidably connected to the inner wall of the second rectangular inner cavity 12. The two sliding blocks 13 are elastically connected by a second spring 14. Limiting blocks 15 are fixedly connected to the opposite sides of the two sliding blocks 13. The left sides of the two limiting blocks 15 are set as arc surfaces, so that the two limiting blocks 15 automatically retract into the second rectangular inner cavity 12 during the process of being inserted into the rectangular inner groove 4. The opposite sides of the two limiting blocks 15 penetrate through the second rectangular inner cavity 12 and extend to the outside. Both of the two limiting blocks 15 cooperate with the corresponding limiting through grooves 6. By inserting the two limiting blocks 15 into the corresponding limiting through grooves 6, stable connection between the first connecting piece 2 and the second connecting piece 3 can be realized.

[0023] In the present utility model, during use, the rectangular clamping block 11 is aligned with the rectangular inner groove 4 and inserted. During the insertion process, since the left sides of the two limiting blocks 15 are both arc-shaped, when contacting the inner wall of the rectangular inner groove 4, the two limiting blocks 15 will move towards each other and retract into the second rectangular inner cavity 12. At this time, the second spring 14 will be compressed under force. When the two limiting blocks 15 move to the positions of the two leftmost limiting through grooves 6, due to the acting force of the second spring 14, the two limiting blocks 15 will move away from each other and insert into the two leftmost limiting through grooves 6, thus completing the stable connection between the first connecting member 2 and the second connecting member 3;

[0024] It is worth mentioning that if the user feels that the tightness of the elastic band body 1 is too loose, the rectangular clamping block 11 can be further controlled to insert into the rectangular inner groove 4, so that the two limiting blocks 15 are inserted into the two deeper limiting through grooves 6 until the tightness of the elastic band body 1 is more comfortable. Subsequently, according to the pressure of the elastic band body 1 on the user, the limiting positions of the two limiting blocks 15 can be changed, thereby controlling the tightness of the elastic band body 1 and ensuring the comfort of the elastic band body 1 during use;

[0025] When it is necessary to disconnect the first connecting member 2 and the second connecting member 3, press the two pressing blocks 10 simultaneously, so that the two pressing blocks 10 move towards each other, driving the two first connecting plates 7 to move towards each other, and enabling the multiple unlocking blocks 8 to be completely inserted into the corresponding limiting through grooves 6, thereby pushing the two limiting blocks 15 out of the corresponding limiting through grooves 6. At this time, the second connecting member 3 can be pulled out of the first connecting member 2. The entire unlocking process is convenient and fast, and regardless of which two limiting through grooves 6 the two limiting blocks 15 are respectively located in, the corresponding limiting can be unlocked.

[0026] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present utility model.
