Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tensioner, especially to a multi-speed take-up tensioner. BACKGROUND

[0002] Tensioner is used in the transportation, movement, shipment or warehousing of goods to fix the goods. They are safe and reliable, portable, easy to operate, and protect the object from damage. It is a device for reinforcing steel formwork and compressed wood board, mainly for tensioning.

[0003] The existing tensioner needs to use the tensioner body and the long head part of the braid when in use. Other light tensioners have a small long head, which is relatively easy to store and use. However, heavy tensioners have a wide and thick braid, and the length is very long. The first problem with the long head of the braid is that it needs to be scattered and inserted into the tensioner, then the length is adjusted for use, and the excess braid is fixed. After use, the long head in the tensioner is taken out and rolled up, which is very tedious and troublesome, and the excess long head of the braid has safety hazards. Although some existing tensioners combine the braid and the tensioner, they often use a spring mechanism. The spring works well for small-sized tensioners. Once the size of the tensioner increases and the braid becomes thicker and wider, the spring cannot be safely rolled up. Either the spring force is too small, the rolling is slow, or even cannot be rolled up, or the spring force is too large, which has safety hazards during rolling. Therefore, it is difficult to meet the use requirements. SUMMARY

[0004] The utility model aims at solving the problem that the long braid and the tensioner are separated in the prior art, and there is excess long braid left during use, which needs to be tied and fixed.

[0028] In use, the winding shaft 201 for accommodating the long woven tape is rotatably arranged on the base 1, the tensioner and the long woven tape are combined, the function of self-storing long woven tapes of various specifications and lengths is solved, the residual long woven tape during use is avoided, the risk of scattering is reduced, the use safety is improved, the service life of the long woven tape is prolonged, after use, the long woven tape does not need to be additionally accommodated, recycling is convenient, placement is convenient, and the use experience is improved; the winding shaft 201 is driven to rotate by the gear ring 203, the planetary gear 303 and the sun gear 202, when the driving handle 302 rotates one circle, due to the number of teeth, the number of teeth of the gear ring 203 is multiple of the planetary gear 303 and the sun gear 202, the winding shaft 201 rotates at a faster speed, the long woven tape can be wound more quickly, and the winding efficiency is improved.

[0029] Referring to Figure 3A sun gear 202 is fixedly installed at one end of the take-up shaft 201. An end cover 3 is rotatably installed inside the take-up reel 2, and the axis of the end cover 3 coincides with that of the take-up shaft 201. A crank handle 302 is rotatably installed on the outer wall of the end cover 3, and a fixed shaft 301 is fixedly installed on the inner wall of the end cover 3. Planetary gears 303 are rotatably installed on the fixed shaft 301. Here, three sets of fixed shafts 301 are evenly arranged, and planetary gears 303 are rotatably installed on each of the three sets. The planetary gears 303 are respectively meshed with the gear ring 203 and the sun gear 202. In use, the end cover 3 is driven to rotate by driving the crank handle 302. Through the meshing of the planetary gears 303 with the gear ring 203 and the sun gear 202, the take-up shaft 201 can be driven to rotate at a faster speed, which helps to improve the winding efficiency.

[0030] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 An adjustment groove 304 is provided on the outer wall of the end cap 3. One end of the crank handle 302 is rotatably positioned within the adjustment groove 304. A retaining ring 204 is fixedly provided on the outer wall of the take-up reel 2. Multiple sets of retaining teeth 205 are fixedly provided on the retaining ring 204. The multiple sets of retaining teeth 205 are evenly distributed circumferentially. There are two to twenty sets of retaining teeth 205, preferably sixteen sets. A retaining groove 305 is provided on one side wall of the crank handle 302. The retaining groove 305 mates with the retaining teeth 205. An elastic piece 7 with an arch bridge structure is provided in the adjustment groove 304. The protrusion of the elastic piece 7 abuts against one end of the crank handle 302. During use, by rotating the crank 302, the slot 305 is disengaged from the tooth 205. At this time, the winding shaft 201 can be driven to wind or unwind by rotating the crank 302. After use, the crank 302 is pushed back to its original position, so that the slot 305 is engaged with the tooth 205. At this time, the winding shaft 201 is prevented from rotating automatically, which would cause the wound long webbing to loosen and affect normal use. Moreover, under the elastic force of the elastic piece 7, the crank 302 can always be engaged with the tooth 205 without other external forces, ensuring normal operation.

[0031] Reference Figures 1-4 Here, we design the tensioning device as follows: a tensioning shaft 401 is rotatably mounted on the other end of the base 1. A webbing groove 402 is provided on the tensioning shaft 401. The free end of the long webbing passes through the webbing groove 402, and a second hook is fixed on the end of the long webbing that passes through the webbing groove 402. Ratchets 4 are fixedly mounted on both ends of the tensioning shaft 401. A baffle 6 is provided on the base 1 to limit the rotation of the ratchet 4. In use, the long webbing can be tensioned by rotating the tensioning shaft 401. At this time, the baffle 6 can limit the ratchet 4 to prevent the ratchet 4 from rotating back and affecting normal use.

[0032] With reference to Figures 1-4 The baffle 6 is slidably arranged on the base 1, one end of the baffle 6 is in engagement with the ratchet teeth of the ratchet wheel 4, a guide plate 601 is fixedly arranged at the other end of the baffle 6, a spring 602 is sleeved on the guide plate 601, and the two ends of the spring 602 are respectively abutted against the baffle 6 and the base 1. In use, the baffle 6 is elastically arranged on the base 1 by the spring 602, when the ratchet wheel 4 rotates to tighten the long woven belt, the ratchet teeth of the ratchet wheel 4 can push the baffle 6 to slide, the ratchet wheel 4 rotates, and after the ratchet wheel 4 stops rotating, the baffle 6 is engaged with the ratchet teeth to limit the ratchet wheel 4 from reversing. When the long woven belt needs to be loosened, the baffle 6 is pushed away from the ratchet wheel 4, and at this time, the end of the long woven belt close to the second hook can drive the ratchet wheel 4 to reverse.

[0033] With reference to Figure 1 And Figure 2 The handle 5 is rotatably arranged on the tensioning shaft 401, the push plate 501 for pushing the ratchet wheel 4 to rotate is slidably arranged on the handle 5, one end of the push plate 501 extends into the tooth groove of the ratchet wheel 4, the pull plate 502 is fixedly arranged on the push plate 501, and the torsional spring 503 for driving the push plate 501 to reset is arranged on the handle 5. In use, the handle 5 is reciprocally pulled to swing, the ratchet wheel 4 is pushed to rotate through the push plate 501, and the long woven belt is tightened, which is simple in structure and reliable in use.

[0034] With reference to Figure 2 The clamping plate 504 is fixedly arranged on the handle 5 and is in engagement with the top of the baffle 6. In use, after the long woven belt is pulled tight, the handle 5 is pushed towards the baffle 6, at this time, the top of the baffle 6 abuts against the clamping plate 504, the baffle 6 cannot slide away from the ratchet wheel 4, the handle 5 limits the baffle 6, and the reliability of the baffle 6 in limiting the ratchet wheel 4 is ensured.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
