[0002] A hose clamp is a type of fastener widely used in the connection of mechanical equipment and pipelines. It mainly consists of a clamp strap, a connector, and flange bolts on the connector. One end of the clamp strap is fixedly connected to the connector, while the other end is inserted into the connector to form a clamping space. The portion of the clamp strap inserted into the connector is threaded onto the flange bolts. During use, the clamping space is adjusted by rotating the flange bolts, thereby adjusting the degree of clamping.

[0003] Currently, the clamping space of hose clamps is mostly circular. The size of the contact area when clamping is affected by the width of the clamp band. The smaller the contact area, the smaller the corresponding clamping force. In order to obtain a greater clamping force, the clamp band needs to be widened, but this greatly increases the production cost. Utility Model Content

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figures 1 to 2 A preferred embodiment of the hose clamp according to this application will be described in detail below. The hose clamp includes a clamp band 10, which is capable of elastic deformation. The clamp band 10 includes at least two band bodies 11 and at least one connecting band 12. Each of the two opposite sides of the connecting band 12 is connected to one of the band bodies 11.

[0023] The hose clamp includes a connector 20. One of the two straps 11, which form the beginning and end portions of the strap 10, has multiple spaced locking structures 111 along its length. The connector 20 is located at the end of the other strap 11 away from the connected connecting strap 12. The connector 20 has a through structure 201, allowing the end of the strap 11 with the locking structure 111 away from the connected connecting strap 12 to be aligned with and inserted into the through structure 201, thus forming a clamping space 1001.

[0024] The hose clamp also includes a clamping member 30, which has threads formed on its circumference. The clamping member 30 is rotatably installed on the connector 20 by inserting into the through structure 201. The clamping member 30 can engage with the locking structure 111 of the belt body 11 inserted into the through structure 201, and when it rotates, it drives the corresponding belt body 11 to move in the direction of insertion or withdrawal from the through structure 201 to adjust the clamping space 1001 to reduce or increase, so as to clamp an object to a pipe or separate the two.

[0025] Preferably, the clamping member 30 is implemented as a screw or a worm gear.

[0026] It is worth mentioning that when the belt 11 with the locking structure 111 is inserted into the through structure 201, the two end faces of the belt 11 with the locking structure 111 are respectively located on two planes perpendicular to the depth direction of the clamping space 1001, and the two ends of at least one of the remaining belts 11 are located at different positions in the depth direction of the clamping space 1001.

[0027] In this way, at least two of the belt bodies 11 remain misaligned, resulting in a larger contact area during clamping compared to common hose clamps. This provides greater clamping force, ensuring a secure clamping, and effectively reduces production compared to increasing the contact area by widening the belt bodies 11.

[0028] Preferably, two belt bodies 11 are provided, and one connecting belt 12 is provided. One belt body 11 has the locking structure 111, and one end of the other belt body 11 is provided with the connector 20. When the belt body 11 with the locking structure 111 is inserted into the through structure 201, the two ends of the belt body 11 connected to the connector 20 are located at different positions in the depth direction of the clamping space 1001.

[0029] Preferably, the connector 20 is welded to one end corresponding to the belt body 11.

[0030] Preferably, the through structure 201 is implemented as a through hole, and one end of the belt body 11 is inserted into the through hole to be welded integrally with the inner wall of the through hole formed by the connector 20. The belt body 11 with the locking structure 111 is inserted into the through hole so that the clamping space 1001 is formed by the connector 20, the remaining belt body 11, and all the connecting belts 12.

[0031] In one embodiment, the through structure 201 is implemented as a through hole, and one end of the corresponding strap 11 is welded to the outer wall of the connector 20. The strap 11 with the locking structure 111 is inserted into the through hole to form the clamping space 1001 together with the remaining straps 11 and all the connecting straps 12.

[0032] In another embodiment, the through structure 201 is implemented as a through groove, and the connector 20 is welded to the corresponding belt body 11 at one end forming the opening of the through groove. The belt body 11 with the locking structure 111 is inserted into the through groove to form the clamping space 1001 together with the remaining belt bodies 11 and all the connecting belts 12.

[0033] Preferably, the locking structure 111 is implemented as an inclined protrusion formed on the corresponding belt body 11, the inclination direction of the inclined protrusion being the same as the helical direction of the circumferential thread of the clamping member 30. The rotating clamping member 30 drives the corresponding belt body 11 to move along the through structure 201 by engaging with the inclined protrusion thread of the belt body 11 inserted into the through structure 201.

[0034] Alternatively, the locking structure 111 is implemented as an inclined notch formed in the corresponding belt body 11, the inclination direction of the inclined notch being the same as the helical direction of the circumferential thread of the clamping member 30. The rotating clamping member 30 drives the corresponding belt body 11 to move along the through structure 201 by engaging with the inclined notch thread of the belt body 11 inserted into the through structure 201.

[0035] refer to Figure 1 It is worth mentioning that the connecting band 12 is partially recessed to form at least one groove 1201. The groove 1201 has two oppositely arranged groove edges 12011 in the depth direction of the clamping space 1001. The portion of the connecting band 12 that forms the groove 1201 can undergo elastic deformation to increase the distance between the two groove edges 12011 of the groove 1201, thereby increasing the friction between the object and the pipe when the object is clamped to the pipe, and thus increasing the clamping force.

[0036] Preferably, when the belt 11 with the locking structure 111 is inserted into the through structure 201, the connecting belt 12 participates in forming the groove 1201 on one side of the inner wall of the clamping space 1001.

[0037] In one embodiment, when the strap 11 with the locking structure 111 is inserted into the through structure 201, the groove 1201 is formed on the side wall opposite to the side of the connecting strap 12 that participates in forming the inner wall of the clamping space 1001.

[0038] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
