Abstract

A strapping tape tightener comprises a fixed base (1) and a movable base (2), wherein the fixed base (1) and the movable base (2) are movably connected, a spindle (3) is arranged at the connecting end of the fixed base (1) and the movable base (2), a ratchet wheel (4) is fixed at the end of the spindle (3), and one end of a first block (5) of the fixed base (1) and one end of a second block (6) of the movable base (2) both movably contact with and match with gear teeth of the ratchet wheel (4) and form a unidirectional rotation positioning mechanism of the ratchet wheel (4). The device is characterized in that two ends of the first block (5) protrude from the outer side of the fixed base (1) and form a protrusion (52), and the side of the movable base (2) is provided with a groove (21) matching with the protrusion (52). When the fixed base (1) and the movable base (2) withdraw, the protrusion (52) is nested inside the groove (21). The device has the advantages that the arrangement of the protrusion (52) and the groove (21) can prevent the situation of strapping tape loosening and dropping due to incorrect operation when the fixed base and the movable base withdraw.

Description

The strapping tightener

Technical field

The utility model relates to the goods bundling technology, especially refers to a kind of strapping tightener that goods bundling is tightened up.

Background technology

Generally all need to use the strapping tighten when Container Loading, transportation, preventing that goods from rocking falls, usually after tying up, need strapping tension and knotting fixing, not only operation effort, and need proficiency skills, not so strapping easily gets loose or ties a knot and can't untie; Existing a kind of patent No. is that the Chinese utility model patent that the CN00210616.7 name is called " Portable binding tape tightening apparatus " discloses a kind of Portable binding tape tightening apparatus, comprise with hook decide arm and with the swing arm of handgrip, the one-way stop sheet is wherein arranged in deciding the arm gathering sill, decide to have in the arm gathering sill to drive the plectrum that ratchet rotates, be loaded into one with coiling body and the ratchet of clamping strap groove.Its simple in structure, easy operation, safe and reliable, laborsaving, tension effect significantly improve, and effectively overcome the shortcomings such as the binding that exists in the prior art is not tight.But its volume is larger, and can not automatically pack up strapping, so its structure is further improved.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of to design ingenious, simple in structure and can automatically pack up the tightener of strapping for above-mentioned prior art problem.

The utility model solves the problems of the technologies described above the technical scheme that adopts: this strapping tightener, the holder that comprising is movably connected connects and sliding seat, the link place of described holder and sliding seat is provided with rotating shaft, the ratchet of one-directional rotation is fixed in roller end, be provided with the first block with the first back-moving spring on the described holder, be provided with the second block with the second back-moving spring on the described sliding seat, one end of described the first block and the second block all cooperates with the gear teeth movable contact of ratchet, consist of the ratchet one-way rotary positioning structure, it is characterized in that: the side that holder is stretched out at the two ends of described the first block forms projection outward, be provided with the groove suitable with projection on the side of described sliding seat, when holder and sliding seat gathering, described projection is embedded in the groove.

As improvement, the concrete structure of described the first block with the first back-moving spring is: an end of described the first block extends to form montant, described the first back-moving spring is placed on the montant, and an end and first block of the first back-moving spring offset, and the other end and holder offset.

As improvement, the concrete structure of described the second block with the second back-moving spring is: an end of described the second block extends to form montant, described the second back-moving spring is placed on the montant, and an end and second block of the second back-moving spring offset, and the other end and sliding seat offset.

As improvement, be provided with the vestibule for weight reduction on the described holder.

Compared with prior art, the side that the utility model adopts the two ends of described the first block to stretch out holder forms projection outward, be provided with the groove suitable with projection on the side of described sliding seat, when holder and sliding seat gathering, described projection is embedded in the groove.Advantage of the present utility model is: holder and sliding seat are opened, the first block and the second block are broken away from ratchet simultaneously, described rotating shaft can be rotated and strapping is packed up by automatic reverse; Again because arranging of projection and groove can prevent when holder and sliding seat are drawn in, because the phenomenon that maloperation gets loose strapping.

The specific embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

Extremely shown in Figure 10 such as Fig. 1, the strapping tightener of the present embodiment, the holder 1 that comprising is movably connected connects and sliding seat 2 are provided with the vestibule 11 for weight reduction on the described holder 1; The link place of described holder 1 and sliding seat 2 is provided with rotating shaft 3, the ratchet 4 of one-directional rotation is fixed in rotating shaft 3 ends, be provided with the first block 5 with the first back-moving spring 51 on the described holder 1, one end of described the first block 5 extends to form montant, described the first back-moving spring 51 is placed on the montant, one end of the first back-moving spring 51 and the first block 5 offset, and the other end and holder 1 offset; Be provided with the second block 6 with the second back-moving spring 61 on the described sliding seat 2, one end of described the second block 6 extends to form montant, described the second back-moving spring 61 is placed on the montant, and an end of the second back-moving spring 61 and the second block 6 offset, and the other end and sliding seat 2 offset; One end of described the first block 5 and the second block 6 all cooperates with the gear teeth movable contact of ratchet 4, consist of ratchet 4 one-directional rotation location structures, the side that holder 1 is stretched out at the two ends of described the first block 5 forms projection 52 outward, be provided with the groove 21 suitable with projection 52 on the side of described sliding seat 2, when holder 1 and sliding seat 2 gathering, described projection 52 is embedded in the groove 21.

Operation principle: the repeatedly gathering by sliding seat 2 and holder 1 is opened, and rotating shaft is rotated, thereby play the purpose of tightening up strapping; When sliding seat 2 and holder 1 gathering, ratchet 4 is blocked by the first block 5, and the second block 6 skids along profile of tooth, and rotating shaft 3 is the rotary tightening strapping along with the gathering of sliding seat 2; When sliding seat 2 and holder 1 opened, ratchet 4 was blocked by the second block 6, and the first block 5 skids along profile of tooth, rotating shaft this moment 3 transfixions.In the time of need to unclamping strapping, sliding seat 2 and holder 1 are opened, mobile the first block 5 and the second block 6 make it compress respectively the first back-moving spring 51 and the second back-moving spring 61 and break away from simultaneously ratchet 4, and ratchet 4 can backward rotation be packed up strapping together with rotating shaft 3; When holder 1 and sliding seat 2 were closed up, the first block 5 upper protruding blocks 52 were embedded in the groove 21 on the sliding seat 2, and at this moment, the first block 5 can't break away from ratchet 4, thereby can effectively prevent from getting loose because maloperation causes strapping.
