Description

Technical Field

[0001] This utility model relates to the field of hose clamp technology, and in particular to a hose clamp that is easy to adjust. Background Technology

[0002] Hose clamps, as core fastening components in pipe connections and fitting fixation, are widely used in water supply and drainage engineering, automotive cooling systems, HVAC ducts, agricultural irrigation equipment, and other scenarios. Their core function is to stably connect hoses to rigid pipes, fitting interfaces, and other structures through clamping force, preventing fluid leakage or component loosening. With the development of industrial equipment integration and lightweighting, and the increasing demand for ease of installation in civilian applications, hose clamps are becoming increasingly common.

[0003] Existing hose clamps mostly use a bolt and nut combination or a single locking bolt structure. Adjustment requires tools such as wrenches and pliers to rotate the nut or locking bolt to achieve the contraction and expansion of the hose clamp band. After adjustment, the locking state of traditional hose clamps mainly relies on the friction between the bolt and nut, or the interlocking force between the locking bolt and the hose clamp band. However, in vibration environments or scenarios with large temperature variations, these frictional or interlocking forces are easily weakened by factors such as relative displacement between components and thermal expansion and contraction, causing the locking bolt to rotate and thus loosening the hose clamp band. For example, hose clamps in automotive cooling systems are constantly affected by engine vibration and coolant temperature fluctuations, often resulting in loose locking bolts and coolant leaks, which not only affect the normal operation of the equipment but may also pose safety hazards.

The positioning mechanism slides with the locking bolt and is inserted and snapped into the hose clamp body to achieve the positioning of the relative angle between the locking bolt and the hose clamp body.

[0006] Preferably, the hose clamp body includes: The hose clamp body, wherein the locking bolt is assembled inside the hose clamp body; A fixing ring is fixedly connected to the end of the hose clamp body, and the interior of the fixing ring has multiple slots arranged in a ring array.

[0007] Preferably, the locking bolt has a groove inside, and the pressing mechanism is slidably disposed inside the groove. The pressing mechanism includes: The pressing block slides into the inner cavity of the groove; An extrusion component is symmetrically mounted on the pressing block, and the extrusion component is interlocked with the positioning mechanism.

When operating the locking bolt, an external screwdriver is inserted into the slot on the locking bolt, pressing the pressing mechanism inward. This causes the pressing mechanism to simultaneously press the two positioning mechanisms, disengaging them from the fixing ring. This unlocks the relative position between the locking bolt and the pressing mechanism, allowing the locking bolt to be rotated. Attached Figure Description

[0015] 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.

[0016] This utility model provides, for example Figures 1-5The adjustable hose clamp shown includes: a hose clamp body 100; a locking device 200 with a positioning function, which is fitted inside the hose clamp body 100 and includes: a locking bolt 201, which is disposed inside the hose clamp body 100; a pressing mechanism 202, which is slidably disposed on the inner side of the end of the locking bolt 201; and a positioning mechanism 203, which is connected to both ends of the pressing mechanism 202. The positioning mechanism 203 is slidably fitted with the locking bolt 201 and is inserted and snapped into the hose clamp body 100 to achieve positioning of the relative angle between the locking bolt 201 and the hose clamp body 100. The positioning mechanism 203 is snapped between the locking bolt 201 and the hose clamp body 100, thereby enabling the hose clamp to be adjusted. Positioning the locking bolt 201 effectively limits its rotation tendency. Even in scenarios such as automotive cooling systems where vibration and temperature fluctuations occur over long periods, the clamp can be stably maintained, preventing fluid leakage caused by loosening of the locking bolt 201. This ensures normal equipment operation and reduces the probability of safety hazards. When operating the locking bolt 201, an external screwdriver is inserted into the slot on the locking bolt 201. The screwdriver presses the pressing mechanism 202 inward, causing it to simultaneously press the two positioning mechanisms 203. This disengages the positioning mechanisms 203 from the fixing ring 102, thus unlocking the relative position between the locking bolt 201 and the pressing mechanism 202, allowing the locking bolt 201 to be rotated.

[0017] The hose clamp body 100 includes: a hose clamp body 101, with a locking bolt 201 assembled inside the hose clamp body 101; and a fixing ring 102, which is fixedly connected to the end of the hose clamp body 101. The fixing ring 102 has multiple slots arranged in a ring array inside. The slots arranged in a ring array facilitate multi-angle engagement of the locking block 232 to achieve multi-angle positioning of the locking bolt 201.

[0018] Specifically, the locking bolt 201 has a groove inside, and the pressing mechanism 202 is slidably disposed inside the groove. The pressing mechanism 202 includes: a pressing block 221, which slides in cooperation with the inner cavity of the groove; a pressing member, which is symmetrically installed on the pressing block 221 and interlocks with the positioning mechanism 203; and a first elastic member, which is installed on one side of the pressing block 221 and provides elastic support for the pressing block 221. The pressing member includes: a bracket 222, one end of which is fixedly connected to the pressing block 221 and slidably interlocks with the locking bolt 201; and a pressing column 223, which is fixedly connected to the other end of the bracket 222 and slidably cooperates with the positioning mechanism 203. The first elastic element includes: a first guide rod 224, one end of which is fixedly installed inside the groove, and the other end of which is slidably connected to the pressing block 221; and a first spring 225, which is movably sleeved on the outside of the first guide rod 224. Through the connection of the bracket 222, the pressing block 221 and the extrusion column 223 can move synchronously. The inclined groove 2311, and the sliding fit between the extrusion column 223 and the inclined groove 2311, facilitate the application of force components to the slider 231. The force direction is adjusted so that the horizontal movement of the pressing column 223 can push the slider 231 to move vertically inside the cavity, so that the two locking blocks 232 can move relative to each other and disengage from the inner cavity of the locking slot, thereby unlocking the relative position between the locking bolt 201 and the fixing ring 102. The sliding interlocking between the first guide rod 224 and the pressing block 221 facilitates the limitation of the movement of the pressing block 221, making the movement of the pressing block 221 more stable. The first spring 225 facilitates the elastic support of the pressing block 221, so as to reset the pressing block 221.

[0019] Specifically, the positioning mechanism 203 includes: a slider 231, with symmetrical cavities at the ends of the locking bolt 201, the slider 231 slidingly disposed inside the cavities, and a groove 2311 formed on the slider 231, the inner cavity of the groove 2311 cooperating with the pressing column 223; a locking block 232, fixedly installed on the slider 231, the locking block 232 slidably interlocking with the locking bolt 201, the locking block 232 cooperating with the inner cavity of the locking groove; and a second elastic member, which is respectively installed on both sides of the slider 231 and is used to elastically support the slider 231. The second elastic element includes: a second guide rod 233, which is fixedly installed inside the cavity; a connecting block 234, which is slidably inserted into the second guide rod 233 and is fixedly connected to the slider 231; and a second spring 235, which is movably sleeved on the second guide rod 233. The opening of the cavity facilitates the sliding space of the slider 231. The mutual cooperation between the locking block 232 and the locking groove facilitates the locking of the angle of the locking bolt 201. The insertion between the connecting block 234 and the second guide rod 233 facilitates the limiting of the linear sliding of the slider 231, making the movement stability of the locking block 232 higher. The second spring 235 provides elastic support for the connecting block 234, making the cooperation between the locking block 232 and the locking groove more stable.

[0020] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
