Abstract

The utility model belongs to the handle technology field, in particular to a handle with a fast demounting structure comprising a handgrip, a tongs, and a handhold, which overcomes the defects of the existing known caliper type demountable handle that: when the locking rod is gradually closed, the extended force outwards is gradually decreased, the stress of the operator hand gradually tends to zero, thereby rendering no hand sense, and whether the clamping is tighten being hard to know; the complete locking and closing is not realized, after releasing the hand, the locking rod can gradually extend, the caliper type demountable handle can break off from the edge of the pan easily. The handle with a fast demounting structure comprises a handgrip, a tongs can stretch and slide positioned in the handgrip, a spring can facilitate the tongs popping out holden between the handgrip and the tongs, and a locking rod can swing provided on the handgrip; the locking rod is arranged with a compression part can expose at the other side of the handgrip, the tongs is arranged with a top part, the handgrip is arranged with a extrusion part can hold on the top part. The utility model has the advantages of obvious distinguishing stretching forces outwards before and after the locking of the locking rod, convenient operation, good hand feeling, and simple structure.

Description

The handle of quick-release structure

Technical field

The utility model belongs to the handle technical field, particularly comprises handgrip, clamp, the handle of the quick-release structure of handle.

Background technology

Chinese patent, the patent No. is to disclose a kind of caliper brake detachable handle in 99211492, handle is provided with locking spring in the top, be provided with the clamp slideway in the handle, be provided with the check lock lever hugging in the handle bottom, clamp are fixedlyed connected with an end of spring and connecting rod respectively, the other end of connecting rod is fixedlyed connected with check lock lever, check lock lever links to each other with handle bottom live axle, and check lock lever is provided with the button boss, the corresponding button hole that is provided with it in clamp and handle top.Above-mentioned known technology has adopted the link gear of connecting rod and check lock lever and clamp, its unlatching need be pushed the button boss that is arranged on the clamp, when handle is in when tightening state, spring equals zero by the power that connecting rod acts on the check lock lever, during button boss on pushing handle, along with the button boss moves downward, spring increases gradually by the power that connecting rod acts on the check lock lever, check lock lever can open automatically afterwards, and clamp get loose.Because check lock lever is arranged on the lower position of handle, relies on the gravity of himself will cause opening automatically of check lock lever.Its shortcoming check lock lever is when closed gradually, outside open power reduces gradually on it, cause when locking is closed, outside tension force is zero, like this, check lock lever is in that to be about to when closed spring action power thereon very little, and on hand stressed of operator trends towards zero gradually, cause no feel, do not know that clamping tightly denys.If locking is not closed fully, after loosing one's grip, check lock lever can open gradually, and the caliper brake detachable handle is easy to come off from the edge of pot.

Summary of the invention

Before the purpose of this utility model is to provide the locking of a kind of check lock lever, its outside tension force maximum, after the locking, its outside tension force is the handle of zero quick-release structure.

For realizing the purpose of this utility model, the handle of described quick-release structure comprises handgrip, be arranged on the clamp of scalable slip in the handgrip, withstand on the spring that clamp is ejected, be arranged on the check lock lever that to swing on the handgrip, described check lock lever is provided with the press section that can expose at the handgrip opposite side, and clamp is provided with the top, and handgrip is provided with the press section that can withstand on the top.

Owing to adopted clamp to be provided with the top, handgrip is provided with the press section structure that can withstand on the top, and when check lock lever was closed fully, clamp and handgrip clamped, and press section is pressed at the top on the clamp, makes in the clamp retraction handgrip, pot can be clamped.Do not withstand on press section fully at the top and go forward, the tension force maximum that check lock lever is outside, the operator keeps being subjected to the outside tension force effect of check lock lever on hand, in case after the top withstood on the press section fully, the outside tension force of check lock lever was zero.The operator can lose the outside tension force of check lock lever on hand, and the expression clamping is tight, and this moment, handle can not open automatically.When pushing the press section, its check lock lever is outwards opened a bit, check lock lever then opens automatically, and clamp and handle unclamp, and the operator can be subjected to the outside tension force of check lock lever on hand.

Description of drawings

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structure chart of the locking state of the convenient detachable handle of the utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the convenient detachable handle of the utility model is described in further detail:

As shown in FIG., the handle of quick-release structure described in the utility model comprises handgrip 1, clamp 2, spring 3, check lock lever 5.Handgrip 1 is tightened to one by body 13 and handle-bar grip lid 14 are formed by screw 15.Clamp 2 is arranged in the handgrip 1, and can slide in handgrip 1, and spring 3 is installed in the tail end of clamp 2, and withstands on the handgrip 1, makes clamp 2 keep protruding in handgrip 1.Described handgrip 1 side is provided with the elongated slot 4 that is used for ccontaining check lock lever 5, and check lock lever 5 is riveted in the elongated slot 4 by rotating shaft 10, and can 10 rotate around the shaft.Described check lock lever 5 is provided with the press section 6 that can expose at handgrip 1 opposite side, and clamp 2 is provided with top 7, and handgrip 1 is provided with the press section 8 that can withstand on the top 7.

Set about 1 during when hand grips with check lock lever 5 clampings closure, check lock lever 5 10 rotates around the shaft, the motion in elongated slot 4 thereupon of press section 8 on it, when press section 8 withstands on the top 7, top 7 drives clamp 2 retractions in handgrip 1, forms dop between clamp 2 ends and the handgrip 1, and the sidewall of pot body is clamped, the pot body is shown in double dot dash line among the figure, and it is lever operated to finish installation.At this moment, elongated slot 4 is passed in press section 6, passes at handgrip 1 opposite side, exposes the side at handgrip 1.Withstand on the top 7 when driving clamp 2 motions at press section 8, spring 3 is compressed.Described press section 8 is provided with roller 9, so that when press section 8 contacts with top 7, utilizes roller 9 to withstand on top 7, makes press section 8 be easy to incision and withstands on the top 7.

When pressing press section 6, check lock lever 5 is to elongated slot 4 movement outside, during position that press section 8 and top 7 are staggered certain, top 7 is subjected to the elastic force effect at the compressed spring 3 of clamp 2 afterbodys, check lock lever 5 is outwards opened, and clamp 2 stretches out outside handgrip 1, finishes the removal handle operation.

The clamping part of clamp 2 is provided with cushion pad 11, can make clamp 2 and handgrip 1 clamping on the pot wall tight.The end of handgrip 1 is provided with edge groove 12, and the flange of pot drops in the edge groove 12, even the pot wall of pot is thinner, because its flange is stuck in the edge groove 12, the whole cooker body can not deviate between handgrip 1 and clamp 2 yet, the pot wall that the suitable various thickness of clamping differ.

The handle of the utility model quick-release structure have check lock lever before locking with locking after, its outside tension force size difference is obviously, and is easy to operate, good hand touch, advantage of simple structure.
