Background technology
At present, in the work high above the ground of industries such as building, fire-fighting, electric power, all will fasten the safety belt during work high above the ground personnel operation, safety belt links to each other with safety rope, and the other end of safety rope is connected on the mounting article.In practical operation, the somebody directly ties up safety rope on shaft-like fixture, and this kind method operates cumbersome, and very dangerous; Have plenty of by hook cover and hang on the shaft-like fixture,,, link up with and be easy to come off can link up with no effective locking mechanism though that this kind method is used is comparatively convenient, thus the initiation human casualty accident.Safety belt hook from external import is greatly improved in security performance several years ago.The main feature of this kind hook is: at the opening of coupler body, also be latch fitting of hinged inside, be equipped with back-moving spring between latch fitting and coupler body, under free state, latch fitting can play the effect of the sealing mouth of hook.The hinged safety piece in the outside of coupler body, between safety piece and coupler body, be equipped with back-moving spring, have type slip pin-and-hole on the safety piece, sliding pin on the latch fitting is through in the type slip pin-and-hole, under free state, sliding pin is positioned at the short hole of type slip pin-and-hole top, and latch fitting is in locking state.In the time of need opening latch fitting, must press safety piece earlier, sliding pin is slipped in the slotted hole from the short hole of type slip pin-and-hole, just can open latch fitting.But in use,, will open latch fitting, fall hook as the careless slightly safety piece of having depressed, accidents caused.
Summary of the invention
The purpose of this utility model is to provide a kind of safer, more comfortable work high above the ground double-safety safety hook that uses.
The utility model is achieved in that this work high above the ground is made up of coupler body, the latch fitting and the safety piece that are hinged on the coupler body with double-safety safety hook, be respectively equipped with back-moving spring between latch fitting and the coupler body and between safety piece and the coupler body, sliding pin on the latch fitting is through in the type slip pin-and-hole on the safety piece, on coupler body, be provided with a secondary insurance institution, this mechanism is made of a block pressur plate, the middle part of pressing plate is hinged on the coupler body, be equipped with back-moving spring between top and the coupler body, its underpart connects a stop pin, matches with the lock pin holes of latch fitting one side.
Slightly has lifted up outward on the top of pressing plate described in the utility model, and have anti-skidding numb line on the outer surface; The back of described latch fitting and safety piece all is hand nest shape, and the back surfaces of latch fitting also has anti-skidding numb line; Also connect a wrist cover band in the bottom of described coupler body.
The utility model work high above the ground is rational in infrastructure with double-safety safety hook; Its profile is consistent with hand shape, operates more easy, comfortable; Set up insurance institution, used saferly, reliable, had the maltilevel security safety performance.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model work high above the ground with double-safety safety hook.
Accompanying drawing 2 is that the A of accompanying drawing 1 is to view.
The specific embodiment
The utility model will be further described with reference to the accompanying drawings.
Can see that from attached Fig. 1 and 2 the utility model work high above the ground is mainly combined by coupler body 1, latch fitting 2, safety piece 3 and pressing plate 4 with double-safety safety hook.Coupler body 1 is horseshoe type, and the bottom has the rope hole, is connected with safety rope 5.Latch fitting 2 is hinged on the top in rope hole by bearing pin 22, the inboard of coupler body 1, and between is equipped with back-moving spring 21, latch fitting 2 can be shut the mouth of hook under the effect of back-moving spring 21.Safety piece 3 is hinged on the outside of coupler body 1 by bearing pin 33, and the top of latch fitting 2 also is provided with back-moving spring 32 between safety piece 3 and coupler body 1, in the type slip pin-and-hole 31 of sliding pin 23 cross-under on the latch fitting 2 on safety piece 3.In a side of safety piece 3, be equipped with a secondary insurance institution that constitutes by pressing plate 4 on the coupler body 1 of latch fitting 2 tops, see also accompanying drawing 2.The middle part of pressing plate 4 is hinged on the coupler body by bearing pin 44, and a back-moving spring 43 is arranged between the top of pressing plate 4 and the coupler body 1, locatees by alignment pin 41, and the bottom of pressing plate 4 connects a stop pin 42, in order to match with lock pin holes on the latch fitting 2.The utility model is under free state, sliding pin 23 on the latch fitting 2 is positioned at the short hole of type slip pin-and-hole 31 tops, latch fitting 2 is sealed the mouth of hook, and be in locking state, this moment, the stop pin 42 on the pressing plate 4 inserted under the effect of back-moving spring 43 in the lock pin holes on the latch fitting 2, latch fitting 2 and safety piece 3 all can't be moved, thereby form the secondary insurance.When needs are opened latch fitting 2, must at first press lower platen 4, make stop pin 42 leave lock pin holes, depress safety piece 3 then, sliding pin 23 is slipped in the slotted hole from the short hole of type slip pin-and-hole 31, just can open latch fitting 2.These move an available hand and finish continuously.For in use being convenient to hold, can make energetically, and have comfort, the utility model has slightly been lifted up pressing plate 4 tops outward, and stamps anti-skidding numb line on its outer surface; Also the back with latch fitting 2 and safety piece 3 is designed to hand nest shape, and also stamps anti-skidding numb line in the back surfaces of described latch fitting 2.The utility model also connects a wrist cover in the bottom of coupler body 1 and is with 6, is with 6 to be enclosed within on the wrist in this cover where necessary, can alleviate fear, guarantees not off-hook of hand, improves safety coefficient.
