Abstract
The utility model provides a clamping mechanism containing a safety lock. The clamping mechanism comprises a housing, a cover body, a clamping member, and a safety lock. A slide groove member and an interference member are disposed in the housing. A stopping protrusion is disposed on the interference member. One side of the cover body is pivoted on the housing, while positioning columns are disposed on the other side of the cover body inwardly in a protruding manner. The clamping member is connected with the slide groove member and slides linearly along the slide groove member. The clamping member is equipped with an operating key, clamping hooks, a containing groove, and an arc slide groove. Two clamping protrusions are disposed in the arc slide groove at an interval. The safety lock is rotatably disposed in the containing groove. A driving groove is disposed on one end of the safety lock, while a clamping portion and a screw bolt are disposed on the other end of the safety lock. The safety lock is accommodated in the containing groove by the combination of a screw and the screw bolt. The clamping portion of the safety lock is disposed in the arc slide groove in a sliding manner and is clamped to and combined with the two clamping protrusions selectively. The clamping hooks of the clamping member are guaranteed to be firmly hooked on corresponding positioning columns in virtue of the safety lock stopping the clamping member from sliding. Therefore, a purpose of avoiding purchase of an extra lock is achieved.

[embodiment]
See also Fig. 1-4 and show, the utility model provides a kind of snap fastener with safety lock, and it comprises housing 10, lid 20, fastener 30 and a safety lock 40.
Be provided with spout 11 and interference piece 12 in the described housing 10, and described interference piece 12 is provided with backstop protruding 121.
One side of described lid 20 is hubbed on the described housing 10, and the opposite side of described lid 20 inwardly convexes with reference column 21; Wherein, the quantity of reference column 21 can be set as required, and in present embodiment, described lid 20 is provided with a plurality of reference columns 21.
Described fastener 30 is connected in described spout 11 and does the straight line slippage along described spout 11, and described fastener 30 is provided with operation keys 31, grab 32, accepting groove 33, and arc chute 34.The quantity of described grab 32 is colluded with the identical confession of quantity of described reference column 21 and is located on the described reference column 21.The angle of described arc chute 34 is set as required, and in the present embodiment, the angle of described arc chute 34 is 120 degree.It is protruding 341 that compartment of terrains are provided with two cards in the described arc chute 34, wherein a card protruding 341 when lid 20 swivelling covers are combined on the described housing 10 near the backstop protruding 121 of described interference piece 12.
Described safety lock 40 is located in the described accepting groove 33 rotatably, can in described accepting groove 33, rotate, thereby and an end of described safety lock 40 be provided with driver slot 41 and insert for instruments and drive described safety lock 40 rotations, the other end is provided with holding section 42 and double-screw bolt 43.In the present embodiment, described driver slot 41 is flat recess, and in other embodiments, described driver slot 41 also can be other shape, as cross recess, is not restricted at this.Described safety lock 40 is contained in the described accepting groove 33 by the combination of screw 44 with described double-screw bolt 43, makes described safety lock 40 in the same plane in conjunction with the back with described fastener 30.The holding section 42 of described safety lock 40 is wavy in the present embodiment, is located in the described arc chute 35 slidably and optionally is combined with protruding 341 blockings of described two cards, makes described fastener 341 be in fixing or removable state.
Under the normality, as shown in Figure 5, described safety lock 40 is in locking condition, at this moment, described driver slot 41 rotations are to an ad-hoc location, the operation keys 31 of described fastener 30 is positioned at primary importance, as shown in Figure 6, the grab 32 of described fastener 30 colludes and is located on the described reference column 21, as shown in Figure 7, described holding section 42 and described fastener 30 wherein one near protruding 341 engagements of the card of described backstop protruding 121, make described fastener 30 can since described backstop protruding 121 be positioned at the glide direction of described holding section 42 and can't move, at this moment, even apply external force in described operation keys 31, described fastener 30 can not move yet, thereby guarantees that described lid 20 keeps being covered on the described housing 10, avoids because misoperation causes the described relatively housing 10 of lid 20 to be opened.
