Description

Technical Field

[0001] This utility model relates to the field of belt technology, and in particular to a belt with quick-adjustment holes. Background Technology

[0002] A belt is a flexible mechanical component that transmits power and motion. It is made of rubber, leather or canvas and is a closed loop with a suitable width. When in use, it transmits torque and rotational motion by frictional contact with two or more pulleys. In order to adapt to different pulleys and operating environments, a belt with quick-adjustment holes is required.

[0003] A belt with quick-adjustment holes refers to a belt with multiple appropriately spaced holes, which, together with a specially constructed buckle, allows for quick and precise adjustment of tightness without the need for repeated threading or laborious adjustment. Simply snap the buckle into the appropriate hole to accommodate different waist sizes, making the operation convenient and efficient.

[0004] Currently available belts tighten the holes in the pulleys by tightening wire rings to adapt to different usage environments. To reduce the deformation caused by tightening the belt, existing technology uses adjustable baffles to cover the holes and adjust their size. However, this adjustment method has drawbacks. The baffles occupy a lot of space, and their rigidity can cause wear on the belt and pulleys during transmission. Smaller baffles cannot cover or adjust the holes, thus reducing the practicality of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a belt with quick-adjustment holes, aiming to improve the problem in the prior art that it is difficult to adjust the holes without affecting the use of the belt.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a belt with quick-adjustment holes, comprising an outer cover, a transmission belt disposed on the inner side of the outer cover, grooves provided on the front and rear sides of the top of the outer cover, movable blocks fixedly connected to the front and rear sides of the top of the transmission belt, a pull rope fixedly connected to the inner side of the movable block, mounting blocks fixedly connected to the left and right sides of the outer side of the pull rope, a locking block fixedly connected to the outer side of the mounting block, and a locking slot block fixedly connected to the left and right sides of the top of the outer cover, the locking slot block engaging with the locking block, and a lubrication mechanism disposed on the inner side of the outer cover, the lubrication mechanism being able to lubricate the device during use.

A bevel gear two is fixedly connected to the outer side of the rotating disk. A rotating rod is rotatably connected to the middle of the inner side of the bladder belt. A bevel gear one is fixedly connected to the outer side of the rotating rod. The bevel gear one and the bevel gear two are meshed together.

[0009] As a further description of the above technical solution:

[0010] A nut is rotatably connected to the top of the apron, and the bottom of the nut passes through the apron and is fixedly connected to the rotating rod.

[0011] As a further description of the above technical solution:

[0012] A sponge pad is provided on the inner side of the bag strap, and a fixing block is fixedly connected to the outer perimeter of the sponge pad. The sponge pad is engaged with the bag strap through the fixing block.

[0013] As a further description of the above technical solution:

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 4The present invention provides an embodiment of a belt with quick-adjustment holes, comprising an outer cover 1, a transmission belt 3 disposed on the inner side of the outer cover 1, the transmission belt 3 being movable along the outer cover 1, grooves 4 being provided on the front and rear sides of the top of the outer cover 1, movable blocks 5 being fixedly connected to the front and rear sides of the top of the transmission belt 3, a pull rope 6 being fixedly connected to the inner side of the movable block 5, pulling the pull rope 6 being able to move the movable block 5, mounting blocks 7 being fixedly connected to the left and right sides of the outer side of the pull rope 6, a locking block 9 being fixedly connected to the outer side of the mounting block 7, and slot blocks 8 being fixedly connected to the left and right sides of the top of the outer cover 1, the slot blocks 8 engaging with the locking blocks 9, the mounting blocks 7 being fixed by the engagement of the slot blocks 8 and the locking blocks 9, and a lubrication mechanism 2 being disposed on the inner side of the outer cover 1, the lubrication mechanism 2 being able to lubricate the device during use;

[0033] Specifically, the operator can hold the mounting block 7 and pull the mounting block 7 to move the pull rope 6. The moving block 5 connected to the pull rope 6 will slide along the groove 4 on the top of the outer cover 1. During the sliding of the moving block 5, it will further drive the transmission belt 3 to move along the inner side of the outer cover 1. As the transmission belt 3 moves, the transmission belt 3 and the opening on the outer cover 1 will intersect or cross. In this way, the hole position can be flexibly adjusted. After the hole position is adjusted, the locking block 9 and the locking groove block 8 are engaged and fixed, thereby locking the position of the mounting block 7.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The lubrication mechanism 2 includes a bladder 201, with multiple bladders 201 fixedly connected to the inner periphery of the outer cover 1. A rotating disk 202 is rotatably connected to the middle of the inner wall of the bladder 201. Multiple holes 203 are provided on the inner side of the rotating disk 202. When the rotating disk 202 rotates, the holes 203 on it will also move accordingly. A bevel gear 206 is fixedly connected to the outer side of the rotating disk 202. The rotation of the bevel gear 206 can drive the rotating disk 202 to rotate. A rotating rod 204 is rotatably connected to the middle of the inner side of the bladder 201. A bevel gear 205 is fixedly connected to the outer side of the rotating rod 204. When the rotating rod 204 rotates, the bevel gear 205 on it will also rotate accordingly. The bevel gear 205 meshes with the bevel gear 206. Rotating the bevel gear 205 can drive the bevel gear 206 to rotate.

[0035] Specifically, emulsion is pre-stored in the bag 201. When the device is running, the bag 201 is squeezed by the rotating wheel to squeeze out the lubricating oil to achieve lubrication. At the same time, the rotating rod 204 rotates and drives the bevel gear 205 on it to rotate synchronously, which in turn drives the bevel gear 206 and the rotating disk 202 that mesh with it to rotate. When the rotating disk 202 rotates, its hole 203 intersects or staggers with the opening of the bag 201, thereby flexibly adjusting the amount of lubricating material discharged.

[0036] Reference Figure 1 , Figure 3 and Figure 5 The top of the bag belt 201 is rotatably connected to a nut 14, the bottom of the nut 14 passes through the bag belt 201 and is fixedly connected to the rotating rod 204. Rotating the nut 14 can drive the rotating rod 204 to rotate. A sponge pad 16 is provided on the inner side of the bag belt 201. Fixing blocks 15 are fixedly connected to the outer perimeter of the sponge pad 16. The sponge pad 16 is engaged with the bag belt 201 through the fixing blocks 15. The sponge pad 16 can absorb lubricating oil to prevent excessive leakage. A sliding groove 19 is provided on the inner side of the outer cover 1. The sliding groove 19 is slidably connected to the transmission belt 3. Sliding along the sliding groove 19 can improve the stability of the transmission belt 3 when it moves.

[0037] Specifically, the nut 14 facilitates the rotation of the rotating rod 204, the sponge pad 16 installed by the fixing block 15 can absorb lubricating oil and prevent excessive overflow during compression, and the slide groove 19 can improve the stability of the transmission belt 3 when moving along the inner cover 1.

[0038] Reference Figure 2 , Figure 3 and Figure 4 A positioning block 10 is fixedly connected to the outer side of the mounting block 7. A positioning hole 11 is provided on the outer side of the positioning block 10. The positioning block 7 can be moved easily through the positioning hole 11 on the positioning block 10. An indicator groove 13 is provided on the top of the moving block 5. An indicator block 12 is provided on the left and right sides of the top of the pull rope 6. The position of the transmission belt 3 inside the outer cover 1 can be easily observed through the indicator groove 13 and the indicator block 12 on it. Multiple fixing rings 17 are fixedly connected to the outer perimeter of the outer cover 1. A protrusion 18 is fixedly connected to the outer side of the fixing ring 17.

[0039] Specifically, the positioning block 10 allows for easy gripping of the mounting block 7, and additional tools can be inserted through the positioning hole 11 to operate it. The position of the pull rope 6 can be easily observed by looking at the indicator block 12 through the indicator groove 13, thereby determining the current position of the transmission belt 3 inside the outer cover 1. The protrusion 18 on the inner side of the fixing ring 17 can enhance the protective effect of the outer cover 1.

[0040] Working principle: Before using the device, first, by holding the mounting block 7, pull the pull rope 6 and the moving block 5 on it, and slide it along the groove 4 on the top of the outer cover 1. As the moving block 5 moves, the transmission belt 3 can move along the inner side of the outer cover 1. By adjusting the intersection and stagger of the openings on the transmission belt 3 and the outer cover 1, the hole position can be adjusted. At this time, the position of the mounting block 7 is fixed by the engagement of the locking block 9 and the locking slot block 8.

[0041] Furthermore, the emulsion stored in the belt 201 can be used to squeeze out the lubricating oil for lubrication when the device is in use. When the rotating rod 204 rotates, the bevel gear 205 on it will rotate accordingly, thereby driving the bevel gear 206 and the rotating disk 202 that mesh with it to rotate. When the rotating disk 202 rotates, the hole 203 on it will intersect and interlock with the opening on the belt 201, which can adjust the amount of lubricating oil discharged.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
