Specific embodiment

With reference to the accompanying drawing and specific embodiment, the utility model will be further described, in order to clearer reason Solve the technical idea of the requires of the utility model protection.

A kind of key chain firmly installed of the utility model as shown in Figs. 1-5, including main part 1, discount 2, torsional spring 3 and lock Part 4,1 bottom of main part have key-ring perforation 11, and 1 top of main part is rotatablely connected with 2 one end of discount, the torsional spring 3 It is arranged on the connecting pin of main part 1 and discount 2,2 bottom of discount has jack 21, and the latch fitting 4 connects with the sliding of main part 1 It connects, discount 2 by being limited on main part 1 by the latch fitting 4 in its top insertion jack 21.

When the utility model is used, 2 hanging buckle of discount on cingulum and is directly compressed into the inside of main part 1, then upper lock pushing member 4 It enables being inserted into jack 21 at the top of latch fitting 4 and hanging buckle can be completed, user, which presses discount 2, so that key chain is loosened, and this is practical It is novel that without reserved location, push switch is set, so that discount 2 opens bigger opening on main part 1, convenient for hanging buckle in difference On the cingulum of size；In addition, key chain only needs drop-down latch fitting 4 that its top is made to leave jack 21 when unlocking, discount 2 is in torsional spring thereafter It is swung out under 3 reseting elasticity effect, so that opening opening between discount 2 and main part 1, user can incite somebody to action from cingulum easily Key chain is removed；The utility model has the characteristics that range of applicability is wide, easy to use, installation is firm.

Preferably, the discount 2 is rotatablely connected by round end pin 5 and main part 1, and the torsional spring 3 is socketed in round end pin 5 On.

More specifically, 3 two ends of torsional spring are inserted into respectively in discount 2 and main part 1, so that key chain torsional spring in unlock 3 two ends compress discount 2 and main part 1 and the two are made to open opening, and key chain is removed from cingulum convenient for user.

Preferably, the discount 2 is c-type, has L-type opening 12 at the top of the main part 1, and the L-type opens 12 mouthfuls of top, It is rotatablely connected with one end of c-type discount 2 by the round end pin 5, when the discount 2 is fixed on main part 1 by latch fitting 4 When, hanging hole 13 is formed between the discount 2 and L-type opening 12；Using the combination of c-type discount 2 and L-type opening 12, key can be made Bigger opening can be opened by being buckled in when fully opening, key chain is removed or hung up convenient for user.

Preferably, 12 inside of L-type opening has for limiting the bayonet 14 for putting end swing position outside discount 2；In key When key ring is locked, the outer swinging end of the discount 2 is located in bayonet 14；Setting bayonet 14 can make 2 end extension design of discount, prevent Only cingulum slides into its gap between main part 1 from 2 end of discount when hanging buckle.

Preferably, when the latch fitting 4 locks discount 2, between 2 bottom edge of bottom edge and the discount of the L-type opening 12 With gap；This is design margin, so that discount 2 will not be stuck because of touching L-type 12 bottom edges of opening when swinging.

Preferably, the latch fitting 4 includes lock pillar 41 and draw piece 42, and the lock pillar 41 is mounted in main part 1 and slides with main part 1 Dynamic connection, the draw piece 42 are mounted on 1 surface of main part and are fixedly connected with draw piece 42, and lock pillar 41 can be allowed by having on the main part 1 It stretches out and is inserted into the slide opening 15 in jack 21；The draw piece 42 is arranged outside main part 1, and user's up/down pull-push piece 42 can make The rise/fall in main part 1 of lock pillar 41 is slided, and makes to be inserted into/leave jack 21 at the top of lock pillar 41, to realize the lock of key chain Locking/unlocking.

It preferably, further include linear springs 6, the linear springs 6 are mounted in main part 1 and are located at 41 downside of lock pillar, One end compresses 1 inner bottom surface of main part, and the other end compresses 41 bottom surface of lock pillar, so that the lock pillar 41 is pressed to discount 2；In Key-ring lock When tight, linear springs 6 compress lock pillar 41 by own resilient, can prevent user's maloperation and lock pillar 41 is made to fall and solve key Key ring effectively provides the reliability of the utility model；In addition, setting linear springs 6 after, due to unlock after lock pillar 41 in straight line bullet Slide opening 15 is stretched out under the action of spring 6, thus when needing hanging buckle, should first pass through drop-down draw piece 42 makes lock pillar 41 glide and by straining at Button 2 is hung over button 2 is then rocked to latched position on cingulum thereafter, then unclamps draw piece 42, lock pillar 41 is straight by part 42 Rise under the action of wire spring 6 and is inserted into jack 21 locking for realizing key chain；Setting linear springs 6 can further improve this The stability of utility model, and simplify hanging buckle process.

Preferably, 42 outer surface of draw piece has anti-skid chequer 421, prevents user's rubber sleeve and can not move draw piece 42。

Preferably, 1 lower part of main part has mounting groove 16, is connected with bottom cover 17, the lock on the outside of the mounting groove 16 Column 41 slides in mounting groove 16, and 16 slot bottom of mounting groove has type type hole 18, and the lock pillar 41 has slot 411, institute Stating has the inserting column 422 being inserted into slot 411 after type type hole 18 on draw piece 42.

Preferably, the slot 411 is square hole, and the section of the inserting column 422 and 411 abutting end of slot is and slot 411 That agrees with is rectangular.

Preferably, described ground lid 17 is fixed by screws on mounting groove 16.

Preferably, referring to attached Figure 4 and 5, the inserting column 422 includes and the top of 18 narrow end of type type hole cooperation and and slot The lower part of 411 cooperations, wherein lower part side length is less than or equal to the width of 18 wide end of type type hole and is greater than 18 narrow end of type type hole Width so that inserting column 422 can be inserted into from 18 wide end of type type hole；Lock pillar 41 is under the action of linear springs 6 towards 2 direction of button After sliding, the lower edge of inserting column 422 is long to be greater than 18 narrow end of convex hole and can not take out from type type hole 18, to prevent from drawing Part 42 falls off on the body 1, and no setting is required that the fasteners such as bolt are installed for the composite structure, simplifies the group of the utility model Stability is improved while dress process.

Preferably, the limiting slot 19 for limiting 42 sliding scale of draw piece is additionally provided on the main part 1；Setting limiting slot 19 can limit The upper push position for determining draw piece 42 prevents draw piece 42 from rising excessively and causing inserting column 422 to fracture with 41 position deviation of lock pillar.

Preferably, 19 groove face of limiting slot has the raised line parallel with 41 glide direction of lock pillar, has on the draw piece 42 There is the groove agreed with raised line, the structure cooperation intensity of draw piece 42 and main part 1 can be improved in raised line and groove cooperation.

For those skilled in the art, it can make other each according to the above description of the technical scheme and ideas Kind is corresponding to be changed and deforms, and all these change and deform the guarantor that all should belong to the utility model claims Within the scope of shield.
