Description

Structure of cable puller

The invention relates to the structure of the cable puller, in particular to a driving component which is driven by the driving component to drive the triggering member to separate or combine the driving component and the fixing component, and to tighten the cable with the present cable puller. The rope can improve the safety of the bundle of goods in order to transport the cargo to the user, and remove the drive assembly from the fixing component according to the state of use, so as to prevent the third person from obtaining the consent or attention of the user. Feel free to change the condition of the rope pulling rope, to prevent the vehicle from falling at high speed, causing the public hazard that may be caused by the vehicle to be excluded, so as to improve the quality of cargo transportation, and by simplifying the cable puller The assembly structure allows the manufacturer to automate the mechanical production of the present cable puller to improve the yield and quality of the cable puller structure.

According to the conventional cable puller, such as the "CARGO BRACING DEVICE" of the US Patent No. 7,350,768 B1 (the Taiwanese new patent No. M319128 "separate cable puller"), the binding seat (10) and the grip (50) can be obtained. Separating or combining, mainly for the two wings (52) of the grip (50) are provided with a symmetrical main groove (54), which is arranged across the control plate (55), and in the main groove (52) of the two wings (52) The spacer is provided with two spring slots (56), and a sleeve (57) is arranged between the two spring slots (56) for inserting the middle hole of the torsion spring (58) and making the torsion spring (58) A spring leg (581) can abut against the side wall of the spring groove (56), and the second spring leg (582) is locked in the predetermined buckle groove (551) of the control board (55), so that the two torsion springs 58) The second spring leg (582) can push the control plate (55) into the ratchet wheel (30) with a symmetrical predetermined elastic force for providing the handle (50) to drive the ratchet wheel (30) for one-way steering, and the control plate (55) Another arcuate blocking portion (59) is riveted, and the blocking portion (59) can close the notch (531), so that the control plate (55) can be separated from the ratchet wheel (30), and the blocking portion (59) thereof Synchronous opening and closing of the slot (531).

The structural disadvantage of the aforementioned U.S. Patent No. 7,350,768 B1 is that the control board (55) The riveting between the arcuate portion (59) has difficulty in manufacturing. Since the control panel (55) and the arcuate portion (59) are riveted together, the main groove of the two wings (52) must be used first ( 54) extending outward, and the extent of its outward extension is limited by the structure of the cable puller, so that the riveting process between the control plate (55) and the arcuate portion (59) does not substantially provide sufficient space for riveting. The operation of the tools has resulted in difficulties in implementation and lack of value in industrial use.

In addition, the aforementioned U.S. Patent No. 7,350,768 B1, in order to provide the control board (55) to cut into the ratchet (30), to provide the handle (50) to drive the ratchet (30) for one-way steering, the two wings (52) The main slot (54) is recessed with two spring slots (56), and a sleeve (57) is arranged between the two spring slots (56) for the middle hole of the torsion spring (58) to be worn and twisted. The first spring leg (581) of the spring (58) can abut against the side wall of the spring groove (56), and the second spring leg (582) is locked in the buckle groove (551) preset by the control board (55). In this way, the two torsion springs (58) will encounter the bottle neck when installed. When the sleeve (57) is the middle hole of the torsion spring (58), the first spring leg (581) of the torsion spring (58) The installation of the second spring leg (582) will result in an elastic reaction force, and because of the small assembly space, the assembly process has many resistances, affecting the production speed, and most of the structural assembly cannot be completed by automated machinery.

Next, in the aforementioned U.S. Patent No. 7,350,768 B1, a guide groove (41) is provided on both side plates (12) to provide a guide plate (42) across the sliding, and the two side plates (12) are spaced apart at the guide groove (41). There are two spring slots (43), so that a sleeve (44) is formed between the two spring slots (43) for inserting the hole in the spring (45), and the first spring leg (451) of the spring (45) can be Abutting against the side wall of the spring groove (43), the second spring leg (452) is locked in the predetermined slot (421) of the guide plate (42), so that the two springs (45) are second spring legs (452) The symmetrical pre-set elastic force pushing guide (42) is cut into the ratchet (30) for limiting the one-way steering positioning of the ratchet (30). Thus, as mentioned above, the two springs (45) will be difficult to install. When the sleeve (44) is sleeved by the middle hole of the spring (45), the first spring leg (451) of the spring (45). The installation of the second spring leg (452) will result in an elastic reaction force, and because of the small assembly space, the assembly process has many resistances, affecting the production speed, and most of the structural assembly cannot be completed by automated machinery.

To this end, the inventors have accumulated years of experience in the manufacture and design of related products, and have studied the shortcomings of the prior art described above, and have invented the present invention.

It is an object of the present invention to provide an automated mechanical device for producing a cable puller, which simplifies the partial structure of the cable puller and enhances the structural utility of the cable puller.

In order to achieve the above object, the cable puller of the present invention is provided with a fixing component, and two symmetrical plates are disposed. The two plates are disposed on two sides of the connecting piece, and the connecting piece is provided with an integrally formed elastic component seat, and then The fixing component is provided with a fastening component, and the elastic component seat is disposed on the fastening component, and the coiled compression elastic component is respectively disposed between the elastic component seat of the connecting piece and the elastic component seat of the fastening component to provide a buckle. The recovery power of the piece simplifies the assembly structure and saves the material cost of the fastener.
