Description
technical field
The utility model relates to novel ocular form suspender belt hook with safety tong.
background technology
Suspension hook is modal a kind of suspender in elevator machinery, and it has advantages of simple in structure, easy to use, by people, is extensively familiar with and uses, and has very long use historical.In the evolution of suspension hook, because it is simple in structure, very slow to the improvement of suspension hook itself, to suspension hook improvement, can pay very large creative work, even if little improvement is also regarded as rare achievement.
Applicant discloses a kind of safety hook rigging in the Chinese utility model patent of the patent No. ZL 201120436925.2 of application on November 08th, 2011, as shown in Figure 1, it comprises coupler body 1, locking suspension rod 2 and file protect 3, and coupler body is circular arc bending, and this coupler body is suitable for connecting chain.The eye of locking suspension rod can not make two-ring fastener pass through, and can not connect two-ring fastener, has limited range of use.The rotating range of locking suspension rod is excessive, causes frequent extruding by the finger being pressed on file protect.It is large that file protect exposes size, makes other object have an opportunity to touch file protect, causes by mistake opening of the mouth of hook, has safety hazard.
summary of the invention
The technical problems to be solved in the utility model is to provide a kind of novel ocular form suspender belt hook with safety tong.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of novel ocular form suspender belt hook with safety tong, comprise coupler body, locking suspension rod and file protect, locking suspension rod has eye, and coupler body has the neck of hook and bill, the neck of hook is positioned at bill left side, crooked coupler body forms groove, and the neck of hook is the jaw with two yokes, the articulated section of locking suspension rod by bearing pin rotary support in jaw, locking suspension rod swings the keying that realizes the mouth of hook, the position of locking suspension rod is controlled by file protect, and groove has straight bottom land with the flat suspender belt of support, and bill is upwardly extending straight shape.
Above-mentioned novel ocular form suspender belt hook with safety tong, the both sides, front and back of the articulated section of locking suspension rod all form rounded convex platform, and the lateral surface of outer lug boss is smooth plane.
Above-mentioned novel ocular form suspender belt hook with safety tong, is positioned on the left surface of the file protect place neck of hook and has recess, and recess is positioned at the middle part of this left surface fore-and-aft direction, and this recess stretches into and presses the file protect that is positioned at the neck of hook for finger.
Above-mentioned novel ocular form suspender belt hook with safety tong, has the flat part that fore-and-aft direction thickness is little compared with other region on eye, flat part for two-ring fastener by so that eye is connected with two-ring fastener.
Above-mentioned novel ocular form suspender belt hook with safety tong, eye is provided with the spacing preiection that limits locking suspension rod full swing position in mouth of hook opening procedure, when the neck of hook touches spacing preiection, has the space that holds finger between locking suspension rod and file protect.
Above-mentioned novel ocular form suspender belt hook with safety tong, the neck of hook is upwardly extending straight shape, and be arranged in parallel with bill.
Groove has straight bottom land, and the bottom land of this structure is applicable to connecting flat suspender belt very much, and the utility model can be applied to the place with suspender belt lifting.Bill is upwardly extending straight shape and is conducive to the immigration of flat sling and shifts out, and suspender belt can be easily and fully fallen into bottom land, makes suspender belt in best strained condition.
accompanying drawing explanation
Below in conjunction with accompanying drawing to further detailed explanation of the utility model:
Fig. 1 is the structural representation of existing safety hook rigging.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of coupler body in Fig. 1.
Fig. 4 is the lateral plan of Fig. 3.
Fig. 5 is the structural representation of locking suspension rod in Fig. 1.
Fig. 6 is the lateral plan of Fig. 5.
In figure: 1 coupler body, 2 locking suspension rods, 3 file protects, 4 bearing pins, 5 necks of hook, 6 bills, 7 grooves, 8 recesses, 9 flat parts, 10 spacing preiections, 11 outer lug boss, 12 eyes.
The specific embodiment
As shown in Figures 2 to 6, a kind of novel ocular form hook with safety tong, comprises coupler body 1, locking suspension rod 2 and file protect 3, and locking suspension rod has eye 12.Coupler body has the neck of hook 5 and bill 6, and the neck of hook is positioned at bill left side, and crooked coupler body forms groove 7, the neck of hook is the jaw with two yokes, the articulated section of locking suspension rod is by bearing pin 4 rotary supports in jaw, and locking suspension rod swings the keying that realizes the mouth of hook, and the position of locking suspension rod is controlled by file protect.Groove has straight bottom land with the flat suspender belt of support, and bill is upwardly extending straight shape.
The both sides, front and back of the articulated section of locking suspension rod all form rounded convex platform 11, and the lateral surface of outer lug boss is smooth plane.When locking suspension rod swings, outer lug boss and coupler body direct friction, and the other parts of locking suspension rod do not contact with coupler body, make the smooth rotation of locking suspension rod, are difficult for being stuck.
Be positioned on the left surface of the file protect place neck of hook and have recess 8, recess is positioned at the middle part of this left surface fore-and-aft direction, and this recess stretches into and presses the file protect that is positioned at the neck of hook for finger.This design can be protected finger, makes file protect not expose simultaneously or exposes less, has avoided the generation of maloperation, has improved safety.
On eye, there is the flat part that fore-and-aft direction thickness is little compared with other region, flat part 9 for two-ring fasteners by so that eye is connected with two-ring fastener.Locking suspension rod can connect two-ring fastener, has expanded range of use.
Eye is provided with the spacing preiection 10 that limits locking suspension rod full swing position in mouth of hook opening procedure, when the neck of hook touches spacing preiection, has the space that holds finger between locking suspension rod and file protect, has prevented that locking suspension rod from rotating excessive extruding finger.
The neck of hook is upwardly extending straight shape, and be arranged in parallel with bill, and this coupler body is convenient to forge.
