Description

Technical Field

[0001] This utility model relates to the field of cervical traction device technology, specifically a quick-adjustment buckle device for a cervical traction device. Background Technology

[0002] A cervical traction device is a medical device used to treat cervical spondylosis. It is designed based on the principle of traction and is a convenient treatment product for patients to use at home. It has the function of relaxing the muscles around the spine and relieving pressure between the vertebrae. Cervical traction devices can be divided into pneumatic cervical traction devices, mechanical cervical traction devices and electric cervical traction devices.

[0003] Traditional inflatable cervical traction devices often lack a convenient and quick adjustment mechanism for tightening, making it difficult for users to make precise adjustments according to their individual needs and affecting the traction effect. In addition, the connection design of the traction device is relatively simple, which makes it easy for it to loosen or break during the inflation process. This not only reduces the effectiveness of the traction device, but may also cause discomfort or safety hazards to the user.

[0004] Therefore, a quick-adjustment buckle device for cervical traction devices is needed to solve the problems of existing cervical traction devices, such as difficulty in quickly adjusting the tightness according to needs, and the simple connection points that are prone to loosening and breaking apart during use. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-adjustment buckle device for a cervical traction device, so as to solve the problems of the existing cervical traction device, which is not easy to quickly adjust the tightness according to the needs, and the simple connection is easy to loosen and break open during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-adjusting buckle device for a cervical traction device, comprising a traction device body, a booster installed on the right side of the outer surface of the traction device body, a fixing belt fixedly connected to the left side of the outer surface of the traction device body, a rectangular block fixedly connected to the outer wall of the front end of the fixing belt, a snap-fit ​​mechanism and an adjustment component provided inside the rectangular block, and a connecting belt fixedly connected to the right side of the outer surface of the traction device body;

[0007] The snap-fit ​​mechanism includes a snap-fit ​​channel and a mounting cavity. The snap-fit ​​channel is formed through the side wall of the rectangular block, and the mounting cavity is formed inside the rectangular block. A movable plate is slidably disposed inside the mounting cavity. Four evenly distributed springs are fixedly connected between the rear end wall of the mounting cavity and the outer rear end wall of the movable plate. Three evenly distributed reverse teeth are fixedly connected to the outer rear end wall of the movable plate. Two symmetrically distributed force-bearing blocks are fixedly connected to the outer front end wall of the movable plate.

[0008] It should be noted that the adjustment component includes two symmetrically distributed movable slots, which are respectively opened on the top and bottom surfaces of the rectangular block. A pressing plate is slidably arranged inside each of the two movable slots. Two parallel springs are fixedly connected between the bottom surface of the movable slot and the bottom surface of the pressing plate. The top surface of the pressing plate extends out of the movable slot and is fixedly connected to a limit block. A connecting slot is opened through each of the two movable slots and the mounting cavity. A connecting rod is slidably arranged inside each of the two connecting slots. The right side of the connecting rod extends into the mounting cavity and a pressing block is fixedly connected to the outer wall of its rear end.

[0009] It is worth noting that a snap-fit ​​insert is fixedly connected to the left outer wall of the connecting strip. The snap-fit ​​insert is inserted into the snap-fit ​​channel and has several evenly distributed positive teeth fixedly connected to its front outer wall. An auxiliary strip is fixedly connected to the left outer wall of the snap-fit ​​insert.

[0010] Furthermore, it should be noted that an adhesive patch is fixedly connected to the outer wall of the front end of the connecting strip, and a patch that cooperates with the adhesive patch is embedded in the outer wall of the front end of the auxiliary strip.

[0011] In a preferred embodiment, the outer walls of the rear ends of the three reverse teeth slide through the inner front wall of the locking channel and are staggered with several positive teeth. The elastic coefficient of the second spring is greater than that of the first spring.

[0012] In a preferred embodiment, the left sides of both connecting rods extend into the corresponding movable grooves and their top surfaces are fixedly connected to the bottom surfaces of the corresponding pressing plates, and the two pressing blocks cooperate with the two force-bearing blocks respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The pressing plate moves the connecting rod, causing the extrusion block to separate from the force-bearing block. Spring 1 pushes the reverse teeth into the installation cavity. After inserting the snap-fit ​​plate into the snap-fit ​​channel, the tightness is adjusted. After releasing the pressing plate, the connecting rod, under the action of spring 2, causes the extrusion block to press against the force-bearing block, thereby causing the reverse teeth to interlock with the forward teeth in the snap-fit ​​channel, locking the snap-fit ​​plate. The operation is simple and the installation tightness can be quickly adjusted, effectively avoiding the problem that it is not easy to quickly adjust the tightness according to the needs when using a cervical traction device.

[0015] 2. By rotating the auxiliary belt, the patch and adhesive pad are bonded together, further improving the installation effect of the traction device body and preventing the connection from loosening and breaking off due to the inflation of the traction device body during use. This effectively avoids the problem that the connection of the cervical traction device is relatively simple and easily loosens and breaks off during use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a traction device body 1, a booster 2 installed on the right side of the outer surface of the traction device body 1, a fixing belt 3 fixedly connected to the left side of the outer surface of the traction device body 1, a rectangular block 4 fixedly connected to the outer wall of the front end of the fixing belt 3, a snap-fit ​​mechanism 5 and an adjustment component 6 provided inside the rectangular block 4, and a connecting belt 7 fixedly connected to the right side of the outer surface of the traction device body 1.

[0023] The snap-fit ​​mechanism 5 includes a snap-fit ​​channel 51 and a mounting cavity 52. ​​The snap-fit ​​channel 51 is opened through the side wall of the rectangular block 4. The mounting cavity 52 is opened inside the rectangular block 4. A movable plate 53 is slidably arranged inside the mounting cavity 52. ​​Four springs 54 are fixedly connected between the rear end wall of the mounting cavity 52 and the rear end outer wall of the movable plate 53. Three reverse teeth 55 are fixedly connected to the rear end outer wall of the movable plate 53. Two force-bearing blocks 56 are fixedly connected to the front end outer wall of the movable plate 53.

[0024] Further as Figure 3 and Figure 4 As shown, it is worth noting that the adjustment component 6 includes two symmetrically distributed movable slots 61. The two movable slots 61 are respectively opened on the top and bottom surfaces of the rectangular block 4. A pressing plate 62 is slidably arranged inside each of the two movable slots 61. Two parallel springs 63 are fixedly connected between the bottom surface of the movable slot 61 and the bottom surface of the pressing plate 62. The top surface of the pressing plate 62 extends out of the movable slot 61 and is fixedly connected to a limit block 64. A connecting slot 65 is opened through each of the two movable slots 61 and the mounting cavity 52. ​​A connecting rod 66 is slidably arranged inside each of the two connecting slots 65. The right side of the connecting rod 66 extends into the mounting cavity 52 and a pressing block 67 is fixedly connected to the outer wall of its rear end.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that a snap-fit ​​plate 8 is fixedly connected to the outer left side of the connecting strip 7. The snap-fit ​​plate 8 is inserted into the snap-fit ​​channel 51 and has several evenly distributed positive teeth 9 fixedly connected to its front outer wall. An auxiliary strip 10 is fixedly connected to the outer left side of the snap-fit ​​plate 8.

[0026] Further as Figure 3 As shown, it is worth noting that the outer wall of the front end of the connecting strip 7 is fixedly connected to the adhesive piece 11, and the outer wall of the front end of the auxiliary strip 10 is embedded with a patch 12 that cooperates with the adhesive piece 11.

[0027] Further as Figure 3 and Figure 4 As shown, it is worth noting that the outer walls of the rear ends of the three reverse teeth 55 slide through the inner front wall of the locking channel 51 and are staggered with several positive teeth 9. Through the staggered engagement of the reverse teeth 55 and the positive teeth 9, the locking plate 8 is locked and limited. The elastic coefficient of the second spring 63 is greater than that of the first spring 54. When the pressing plate 62 is not subjected to external force, the force block 56 and the pressing block 67 remain in contact, thereby keeping the reverse teeth 55 and the positive teeth 9 in an staggered engagement state, preventing the locking plate 8 from coming out of the locking channel 51.

[0028] Further as Figure 3 and Figure 4 As shown, it is worth noting that the left sides of both connecting rods 66 extend into the corresponding movable slots 61 and their top surfaces are fixedly connected to the bottom surfaces of the corresponding pressing plates 62. This facilitates the movement of the connecting rods 66 via the pressing plates 62, causing the force-bearing block 56 to separate from the pressing block 67, thereby releasing the lock on the snap-fit ​​plate 8 and facilitating adjustment. The two pressing blocks 67 cooperate with the two force-bearing blocks 56 respectively. Through the cooperation between the pressing blocks 67 and the force-bearing blocks 56, it is easy to push the moving plate 53 to drive the reverse teeth 55 to move.

[0029] In summary: When using this cervical traction device, first, place the traction device body 1 around the user's neck. Simultaneously, press the two pressing plates 62 to move the connecting rod 66, which in turn compresses the second spring 63. The connecting rod 66 causes the compression block 67 to separate from the force-bearing block 56. Under the action of the first spring 54, push the moving plate 53 to retract the reverse teeth 55 into the mounting cavity 52. ​​At this time, pass the auxiliary belt 10 through the locking channel 51. When the locking plate 8 is inside the locking channel 51, slowly pull the auxiliary belt 10 according to the user's feeling. When the locking plate 8 is inside the locking channel 51... When moved to the appropriate position, release the two pressing plates 62. Under the action of the second spring 63, push the pressing plates 62 to drive the connecting rod 66 to reset and move, so that the squeezing block 67 squeezes the force block 56, thereby causing the moving plate 53 to push the reverse tooth 55 into the snap-fit ​​channel 51 and interlock with the positive tooth 9, realizing the locking and limiting of the snap-fit ​​plate 8, completing the initial installation and fixation of the traction device body 1. The operation is simple and the installation tightness can be quickly adjusted, effectively avoiding the problem that it is not easy to quickly adjust the tightness according to the needs when using the cervical traction device.

[0030] After the initial fixation of the traction device body 1 is completed, the auxiliary belt 10 is rotated to bond the patch 12 and the adhesive patch 11, further improving the installation effect of the traction device body 1 and preventing the connection from loosening and breaking off due to the inflation of the traction device body 1 during use, thus affecting the use effect. Finally, the traction device body 1 is inflated by the booster 2 to provide traction support for the user's neck, effectively avoiding the problem that the connection of the cervical traction device is relatively simple and easy to loosen and break off during use.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
