[0002] The development of the transportation industry today has led to the rise of the tensioner product. After being locked, they will not fall off, are safe and reliable, lightweight, easy to operate, and protect objects from shaking damage.

[0003] Most of the current tensioners are supplied to logistics companies, so the storage of the tensioners and webbing is not considered, which makes it inconvenient for ordinary individual users to use, because in most cases the webbing can only be rolled up and then stuffed together. In addition, when in use, the excess belt will float around, which is extremely unsafe if the webbing flaps around when riding a two-wheeled vehicle. Summary of the invention

[0004] The utility model aims to solve the above-mentioned deficiencies of the prior art and provide a tensioner for automatically recovering a webbing, which is easy to operate, labor-saving, simple and convenient to use.

[0005] The technical problem of the utility model is achieved through the following technical solutions:

[0006] In order to realize this automatic recovery of the webbing tensioner, it includes a base, a handle arranged in the base, a flanged shaft sleeve to ensure that the base and the handle center hole are coaxial, and a ratchet piece arranged in the handle and a ratchet shaft connecting the two ratchets, through which the middle axis passes, and the upper baffle is fixed on the handle through a hole. The pressure provided by the torsion spring 2 allows it to be attached to the contour of the ratchet or the base. The lower locking piece is provided with force by the pagoda spring so that it can lock and release the ratchet group through the cam structure on the handle on the track designed for the base, and the front baffle is provided through The hole on the base is fixed to the force of the torsion spring, which can be tightly attached to the contour of the ratchet or handle. The power of the whole product is provided by the spiral spring set at one end of the central axis and the notch at the end of the central axis, which is protected by the coil spring box. The whole product is fixed by the rivet fixing shaft, and its appearance part front face and comfortable tail pressing key are characterized in that: the upper baffle is pressed by pressing the rear tail area to achieve the fit and separation with the ratchet or base, and the universal upper baffle is pressed over the convex point on the base to achieve the gear switching. The convex point on the handle can push the front baffle and the lower locking plate when the handle rotates with the central axis as the axis, and cooperate with the upper baffle to realize the easy pulling out of the webbing in the semi-unlocked state.

[0007] The tensioner for automatically recovering the webbing is characterized in that the upper circumference of the base is provided with a locking groove and a semi-locking groove. When the product is in the locking mode, the force-bearing part of the upper baffle is located in the locking groove, and the convex point of the handle will squeeze the front baffle, and the convex point will release the lower locking plate, and the lower locking plate will lock the ratchet. At this time, pushing the handle makes the force-bearing part of the upper baffle push the ratchet to rotate and tighten the webbing. Due to the characteristics of the ratchet, the lower locking plate will prevent the ratchet from reversing.

[0008] The tensioner for automatically recovering the webbing is characterized in that the upper circumferential portion of the base is provided with a locking groove and a semi-locking groove. When the product is in the semi-locking mode, the force-bearing part of the upper baffle is located in the semi-locking groove. The semi-locking groove is higher than the ratchet so the upper baffle cannot act on the ratchet. The convex point of the handle will not squeeze the front baffle open, but the convex point will push open the lower locking plate. At this time, the lower locking plate will not lock the ratchet. At this time, the webbing can be directly pulled out without other operations and will not be automatically recovered. Pressing down the handle causes the convex point on the handle to push open the front baffle. At this time, the ratchet will automatically recover without interference due to the force of the spiral spring.

[0009] The automatic webbing retractor is characterized in that the base and the handle are both U-shaped parts, and their cooperation is that the base covers the handle, or the handle covers the base.

[0010] The described automatic webbing tensioner is characterized in that the spiral spring is matched with the slotted groove of the central axis, and the force transmission is achieved through the match between the flat position on the central axis and the flat position on the ratchet, and is fixed to the base or handle by rivets through the coil spring box. This device can be set on the left or right side of the automatic webbing tensioner.

[0011] Compared with the existing technology, the tensioner of the automatic retractable webbing has a new semi-locking mode. When the product is fixed on a vehicle such as a pickup truck, motorcycle, or yacht, the webbing can be directly pulled out in the semi-locked state. There is no need to hold down the unlock button with one hand and pull the webbing with one hand. In addition, the overall structure is simple, and the button operation is simple and convenient, which can effectively improve the market competitiveness of the product.

DETAILED DESCRIPTION

[0021] The embodiments of the present invention will be described in detail below according to the above-mentioned drawings.

[0022] like Figure 1-8 As shown, it is a ratchet-type small auxiliary binding tool for quickly and labor-savingly binding and tying goods, and its structure is mainly composed of a base 1, a handle 2, a ratchet 141, a fixing webbing 15 and a tensioning webbing 16.

[0023] The base 1 is as Figure 2As shown, it is composed of a bottom plate and two side plates perpendicular to the bottom plate at 90 degrees, so that a "U"-shaped structure is formed. The upper end of the plate is provided with a locking groove 105 and a semi-locking groove 104, and a convex point 102 can separate the two gears, so that the upper baffle 4 can be switched and fixed between the two gears. The locking groove 105 and the semi-locking groove 104, wherein the height of the locking groove 105 is lower than the outer contour line of the ratchet 141, can make the upper baffle 4 support the ratchet 141; wherein the height of the semi-locking groove is higher than the outer contour line of the ratchet 141 so that the upper baffle 4 will not block the rotation of the ratchet 141. A track 101 is also provided on the base, in which the lower locking plate 5 can reciprocate under the force of the pagoda spring 51 and the push of the convex point three 23. And a hole two 103 is provided at the front of the side plate, so that the front baffle can be connected to the base. A stacked center axis hole is designed on the side panel to cooperate with the handle 2 through the center axis 6. In order to make the cooperation more precise, a flanged sleeve 61 is used. The center axis cooperates with the ratchet 141 through the flat position and cooperates with the spiral spring 12 through the groove to form a power system.

[0024] The power system is as follows Figure 8 As shown, the middle axis passes through the flanged sleeve 61, and then cooperates with the ratchet 141 through the flat position. The two ratchets 141 are connected through the ratchet shaft 14, and then pass through the flanged sleeve 61 on the other side and use the circlip to fix the middle axis 6 so that it will not shake. The groove is matched with the spiral spring 12, and then the coil spring box 13 is covered to ensure the beauty and safety of the product.

[0025] The upper baffle 4 is as shown in Figure 2 and Figure 5 As shown, its rear end is upturned and fixed on the handle 2 through the second hole 21, so the upper baffle 4 can be easily lifted up by pressing, and the pressing return can be achieved through the torsion spring 41. The lower locking piece 5 can be reciprocated back and forth through the pagoda spring 51 and the track 101, and the handle 2 rotates around the central axis 6. When the upper baffle 4 is in the semi-locking groove, the convex point 3 23 on the handle 2 will push the lower locking piece 5 away from the ratchet 141. At this time, the upper baffle 4 is also separated from the ratchet 141, and only the front baffle 3 will contact the ratchet 141; when the upper baffle 4 is in the locking groove, the convex point 3 23 on the handle 2 will leave the lower locking piece 5, so that it contacts and locks the ratchet 141. At this time, the upper baffle 4 is also against the ratchet 141, and the front baffle 3 will leave the ratchet 141 due to the boss 25.

[0026] The front baffle 3, when the upper baffle 4 is in the locking groove, the boss 25 on the handle 2 will push it open, so that it does not participate in the state of pulling the mirror and locking; when the upper baffle 4 is in the semi-locking groove, the boss 25 on the handle 2 will not push it open, and at this time, the upper baffle 4 and the lower locking piece 5 will not affect the ratchet 141. Figure 5As shown, at this time, the front baffle 3 will lean against the ratchet 141, and the torsion spring 131 will exert a force on it, and this force is greater than the rotational force exerted by the spiral spring 12 on the ratchet 141, so that the tensioning belt 16 can be freely pulled out without being recovered.

[0027] like Figure 5 As shown, when the upper baffle 4 is in the semi-locking groove 104, the handle 2 is pressed downward, and the convex point 3 23 on the handle 2 will push the front baffle 3 away. At this time, the ratchet 141 has no resistance, and the webbing will automatically recycle the webbing 16. After the recycle is completed, the pressing is released, and the convex point 3 23 that presses against the front baffle 3 will leave, and the force of the torsion spring 1 31 will make the front baffle 3 continue to fit the ratchet, waiting for the next use.

[0028] The tensioner for automatically recovering the webbing obtained by this embodiment is simple to operate when the webbing is recovered, and is also extremely simple and convenient to use in a fixed state. It can be used by one person with one hand. The overall structure is simple, and the button operation is simple and convenient, which can effectively improve the market competitiveness of the product.
