1. Field of the Invention
The present invention relates to a hand puller to hang a fixed hook, and more particularly to a positioning hook structure for the hand puller.
2. Description of the Prior Art
A conventional hand puller is used to position merchandise on a stack board or a platform by matching with a rope.
Referring to
The base 21 includes a first end and a second end, and the first end includes a fixing shank 211 to fix a rope.
The rotating member 22 includes a first segment and a second segment, the first segment of the rotating member 22 is axially connected with the second end of the base 21 so that the rotating member 22 rotates relative to the base 21.
The central shaft set 23 is axially coupled with the first segment of the rotating member 22 and the second end of the base 21.
Each of the two ratchets 24 includes a plurality of teeth arranged around one end of the central shaft set 23.
The base 21 includes a movable retainer 212 to abut against one of the teeth of the ratchet 24.
The rotating member 22 includes a movable pulling rod 221 to abut against another tooth of the ratchet 24, and the rotating member 22 is rotated to control the ratchets 24 to rotate the central shaft set 23.
A fixed rope assembly 25 includes a first rope 251 connecting with a first hooking member 252, and the first rope 251 is rolled around the fixing shank 211 of the base 21 to be sewn together in an overlapping manner.
A movable rope assembly 26 includes a second rope having one end to connect with a second hooking member, and another end of the second rope is fixed on the central shaft set 23 so that when the central shaft set 23 rotates, it rolls the second rope.
However, such a conventional hand puller still has the following defects:
1. After the fixing shank 211 is disposed on the base 21, the fixed rope assembly 25 is further provided on the base 21, and the first rope 251 of the fixed rope assembly 25 is rolled around the fixing shank 211 so that two ends of the first rope 251 are overlapped to be sewn together, having a high production cost.
2. After the first rope 251 of the fixed rope assembly 25 is rolled around the fixing shank 211 and two ends of the first rope 251 are overlapped to be sewn together, the sewn first rope 251 is easy to be cut due to a pulling force during operating the hand puller.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a positioning hook structure for a hand puller that includes a positioning hook being capable of connected to a base by using two insertions of two sides of a third end of the positioning hook and a hooking portion of a fourth end of the positioning hook so that the hand puller is fixed by ways of the positioning hook without using an axial pivot, a belt, and a hooker to lower a sewing cost and a production of the axial pivot, the belt, and the belt.
Further object of the present invention is to provide a positioning hook structure for a hand puller that is coupled with a base of the hand puller by means of the positioning hook without applying the belt to prevent the belt from being cut by a pulling force.
Another object of the present invention is to provide a positioning hook structure for a hand puller that is fixed by using the positioning hook without using the axial pivot and the belt to lower a production cost of the hand puller and prevent from an environmental pollution by a scrapped belt.
To obtain the above objectives, a positioning hook structure for a hand puller that provided by the present invention contains:
a base including a first end and a second end, the first end including two sides, and the two sides of the first end including two holes formed thereon respectively and being symmetrical to each other;
a rotating member including a first segment and a second segment, the first segment of the rotating member being axially connected with the second end of the base so that the rotating member rotates relative to the base, and the second segment of the rotating member including a handle disposed thereon;
a central shaft set being axially coupled with the first segment of the rotating member and the second end of the base;
two ratchets, each including a plurality of teeth arranged around a peripheral side thereof and to be fixed onto one end of the central shaft set;
the base including a movable retaining member to abut against one of the teeth of the ratchet, the rotating member including a movable pulling rod to abut against another tooth of the ratchet, the rotating member being rotated to control the ratchets to rotate the central shaft set;
a positioning hook being made of a metal material and including a third end and a fourth end, the third end of the positioning hook including two sides, each side including an insertion, the fourth end of the positioning hook including a hooking portion extending outward so that the positioning hook inserts to the holes of the base by using the insertions.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
With reference to
The base 11 includes a first end and a second end, the first end includes two sides, and the two sides of the first end include two holes 111 formed thereon respectively and are symmetrical to each other.
The rotating member 12 includes a first segment and a second segment, the first segment of the rotating member 12 is axially connected with the second end of the base 11 so that the rotating member 12 rotates relative to the base 11, and the second segment of the rotating member 12 includes a handle 121 disposed thereon.
The central shaft set 13 is axially coupled with the first segment of the rotating member 12 and the second end of the base 11.
Each of the two ratchets 14 includes a plurality of teeth arranged around a peripheral side thereof and to be fixed onto one end of the central shaft set 13.
The base 11 includes a movable retaining member 112 to abut against one of the teeth of the ratchet 14.
The rotating member 12 includes a movable pulling rod 122 to abut against another tooth of the ratchet 14, the rotating member 12 is rotated to control the ratchets 14 to rotate the central shaft set 13.
The positioning hook 15 is made of a metal material and integrally twist formed, press formed or weld formed, the positioning hook 15 includes a third end and a fourth end, the third end of the positioning hook 15 includes two sides, each side includes an insertion 151 extending inward or outward, the fourth end of the positioning hook 15 includes a hooking portion 152 extending outward so that the positioning hook 15 inserts to the holes 111 of the base 11 by using the insertions 151, after the insertions 151 insert to the holes 111, the end portions of the insertions 151 are fixed in a pressing, twisting, riveting, or locking manner.
The movable rope assembly 16 includes a rope having an end to connect with a fastening member and having another end fixed on the central shaft set 13 such that when the central shaft set 13 rotates, it rolls the rope.
