Problems solved by technology

[0004] But a kind of automatic take-up and tensioning machine of the above-mentioned structure still has obvious technical defects, specifically: considering that the main parts of the above-mentioned automatic take-up and tensioning machine are made of metal materials, the parts are directly exposed Not only will it affect the appearance of the product, but the metal parts are directly exposed and in contact with the operator's hands. The edges of these parts are sharp, which may bring discomfort to the operator and even scratch the skin of the operator's hands. There are potential safety hazards; furthermore, considering that the above-mentioned automatic belt tensioning machine needs to be used in relatively harsh weather conditions (such as rain and snow) for a long time, these exposed metal parts are prone to oxidation or oxidation when they come into contact with water. Other chemical reactions will seriously affect the performance and life of the above-mentioned automatic tensioning machine
If the automatic take-up and tensioning machine of the above structure is installed with a protective shell for the main body of the automatic taking-up and tensioning machine, and is a protective shell made of plastic material, considering the above-mentioned automatic take-up and tensioning machine structure. The handle must be reciprocated to drive the ratchet to rotate to realize the belt retraction. The reciprocating motion of the handle is relatively large, and its running track is an arc. As a result, a large enough opening must be reserved on the above-mentioned protective shell for The movement of the handle causes the part of the main body of the automatic belt tightening machine to still be exposed, which still cannot completely and effectively solve the above-mentioned technical defects

Embodiment 1

[0031] Such as Figure 1-7 As shown, an automatic take-up tensioning machine provided in this embodiment includes a base 1 with a groove 1-1 shape in cross section, a long webbing 2 and a short webbing 3, in the recess of the base 1 The slot 1-1 is provided with a ratchet wheel 4 which is sleeved on each end of both sides, and a shaft sleeve 5 with an opening 5-1 in the axial direction. The shaft sleeve 5 is hinged to the On a pair of side wall parts 1-2 of base 1, one side of base 1 is provided with coil spring 7, and one side end of rotating shaft 6 passes through its corresponding side wall part 1-2, and with coil spring The inner end 7-1 of 7 is connected, and a fixed shaft 8 arranged parallel to it is arranged on one radial side of the shaft sleeve 5, and the ends on both sides of the fixed shaft 8 extend to their corresponding side wall parts respectively. 1-2, a ratchet 9 hinged to a pair of side wall parts 1-2 of the base 1 is provided between the sleeve 5 and the fix...

Embodiment 2

[0037] A kind of automatic take-up tensioning machine provided in this embodiment, its general structure is consistent with embodiment 1, as Figure 8 As shown, but the protective case 12 in this embodiment is mainly composed of three parts: the left half case 12-3, the right half case 12-4 and the coil spring cover 12-5, and the coil spring 7 is located in the coil spring cover 12 -5, and the coil spring cover 12-5 is fixed on the side wall part 11-2 of the base 1 on the corresponding side of the coil spring 7, after the left half shell 12-3 and the right half shell 12-4 are combined and fixed An accommodating chamber for sealing the base 1, the coil spring 7 and the coil spring cover 12-5 is formed.

[0038] For the above-mentioned automatic take-up and tensioning machine, considering that the coil spring 7 is a vulnerable part, and once damaged, it will directly affect the automatic take-up function of the automatic take-up and tensioning machine, so a coil spring is added ...

Embodiment 3

[0040] A kind of automatic take-up tensioning machine provided in this embodiment, its general structure is consistent with embodiment 2, as Figure 9 with Figure 10 shown, but one side of the lock plate 11 in this embodiment is provided with the second protruding part 11-3 for driving the ratchet 9 to compress a pair of ratchet wheels 4 when the lock plate 11 rotates, the first protrusion The part 11-1 is located below the second raised part 11-3, and a gap 11-4 is formed between the first raised part 11-1 and the second raised part 11-3, and there is no external force Under the influence of the torsion spring 10, the ratchet 9 is always snapped into the notch 11-4.

[0041] The above-mentioned lock plate 11 can promote the ratchet 9 engaged on a pair of ratchet wheels 4 to disengage from the ratchet wheel 4, and at the same time lift the handle portion 11-2 of the lock plate 11, and the second raised portion 11-3 of the lock plate 11 counterclockwise direction, the lock p...

Abstract

The invention discloses a tensioning machine capable of withdrawing tapes automatically. A fixing shaft and a shaft sleeve are arranged in a groove in a base, wherein the ends of the two sides of the shaft sleeve are each sleeved with a ratchet wheel, and the shaft sleeve can rotate around the shaft. A coil spring is arranged at one side of the base. The end of one side of a rotating shaft penetrates a side wall part corresponding to the rotating shaft and is connected with the end of one side of the coil spring. A pawl is arranged between the shaft sleeve and the fixing shaft, wherein the pawl is hinged to the pair of side wall parts of the base. The fixing shaft is provided with a torsional spring, wherein the torsional spring always drives the pawl to be engaged with the pair of ratchet wheels without being influenced by any external acting force. A locking plate is arranged between the ratchet wheel at any side and the side wall part corresponding to the ratchet wheel, wherein each locking plate is movably connected to the rotating shaft in a sleeving manner. A first protruding part is arranged at one side of each locking plate, wherein each first protruding part is used for driving the pawl to break away from the pair of ratchet wheels when the corresponding locking plate rotates. A protective shell used for sealing the base and the coil spring is further arranged outside the base. The end of the other side of the coil spring is fixed to the protective shell. By means of the tensioning machine, the technical effect that the service life of the tensioning machine capable of withdrawing the tapes automatically is prolonged is achieved; and the tensioning machine has the beneficial effect of being long in service life.
