Description

Two road insurance bag buckles

Technical field

The utility model relates to a kind of two road insurance bag buckles.

Background technology

Existing box fastener comprises hinged fastening clip, after mutually pushing, be out of shape, snaps together by kinge-joint knot and clip.The box fastener of this structure has two large shortcomings: one, easily in the time of collision, throw off voluntarily; Two, can open arbitrarily without instrument.

Summary of the invention

In order to solve, existing box fastener time easily comes off in collision, unstable problem, the utility model proposes a kind of fasten tight, easily fasten, easily open and with the anti-disengagement insurance of multiple tracks Er road insurance bag buckle.

Two road insurance bag buckles described in the utility model, is characterized in that: comprise button, lower fastener, locking device, slide block, spring, described upper button is hinged on described lower fastener by the first pin; Snap fit, end and lower fastener hinged place that described upper button upper end is provided with for hooking mould assembling lid are semicircular structure; Described lower fastener is hinged on casing by the second pin; Described locking device comprises lock core, lock housing, dead bolt and locking closure, described lock core is enclosed within lock housing, and described lock core connect synchronize with lock core rotation dead bolt, described locking closure is pushed down dead bolt and lock housing, described locking closure is screwed on lower fastener; Described slide block is spacing at lower fastener surface sliding by the second pin and locking closure, described slide block bottom is connected with one end of described spring, the other end of described spring is connected with lock housing, and described slide block slides and self-resetting in lower fastener by spring and the second pin.

Described slide block top is provided with projection, two sides end symmetrical the chute that is stuck in lower fastener sidewall, and described chute protrudes to the both sides of slide block, and the remainder of slide block is all contained in lower fastener; On lower fastener top board directly over projection described in being positioned at, arrange and hold the through hole that projection frees in and out; Described lower fastener both sides are respectively provided with a slot, and the semicircular structure of described upper button inside wall is provided with for being against the boss on the chute of slide block side.

When described upper button axis and described lower fastener axis overlap, the top edge of described boss is equal with the slot edge of lower fastener end; Described upper button axis and described lower fastener axis angle are greater than 0 while spending, and the slot edge that described protruding edge of table exceeds homonymy is against on the chute of slide block lateral end.

Described dead bolt side is provided with projection, and in the time of key operated state, the projection of described dead bolt is vertical with the glide direction of slide block; In the time of key locking state, the projection of described dead bolt is against the bottom of described slide block.

Use procedure: under buckling state, slide block is positioned at the top side of lower fastener under the effect of spring, and lower fastener can only rotate around the second pin, and the projection of slide block has exceeded the radius of gyration of the second pin, lower fastener cannot be rotated, thereby restriction box fastener is opened; Need open box fastener time, slide block is pressed downwards, the projections collapse of slide block is entered in lower fastener, lower fastener can be rotated around the second pin, because upper button is to be hinged on lower fastener by the first pin, when lower fastener rotation, can drive button to move upward, thereby make button depart from case lid, can open box fastener; Because slider bottom is provided with spring, box fastener is opened and is unclamped by after the power of movable slider, and slide block can automatically reset under the effect of spring, can cause need again fasten box fastener time, and the projection of slide block exceeds radius of gyration makes lower fastener cannot rotate to closed angle; Therefore both sides are respectively provided with a rectangular row hole on lower fastener, on the semicircular structure of the inside wall of upper button, be provided with for being against the boss on the chute of slide block side; Under box fastener closure state, the rectangular row hole plane parallel of the concave station of upper button and lower fastener and equal can be slided slide block in lower fastener, and under box fastener opening, the boss of upper button has exceeded the rectangular row hole of lower fastener, has blocked the reset of slide block; Dead bolt is in the time of key operated state, and the projection of dead bolt, perpendicular to the glide direction of slide block, makes slide block have certain sliding space, and now box fastener can be opened and fasten; Dead bolt is in the time of key locking-in state, and the projection of dead bolt is parallel to the glide direction of slide block, and the projection of dead bolt withstood slide block, and slide block cannot be slided again, and now box fastener cannot be opened.

The beneficial effects of the utility model are: this box fastener fastens sternly, easily opens, easy to use, simple to operate, have overcome the problem that traditional box fastener is easily thrown off voluntarily, can be opened arbitrarily without instrument in the time of collision.

Detailed description of the invention

Further illustrate the utility model below in conjunction with accompanying drawing

With reference to accompanying drawing:

Embodiment 1 two road insurance bag buckles described in the utility model, comprise button 1, lower fastener 2, locking device 3, slide block 4, spring 5, described upper button 1 is hinged on described lower fastener 2 by the first pin 11, and snap fit 12, end and lower fastener 2 hinged places that described upper button 1 upper end is provided with for hooking mould assembling lid 6 are semicircular structure 13; Described lower fastener 2 is hinged on casing 7 by the second pin 21; Described locking device 3 comprises lock core 31, lock housing 32, dead bolt 33 and locking closure 34, described lock core 31 is enclosed within lock housing 32, and described lock core 31 connects synchronizes the dead bolt 33 of rotation with lock core 31, described locking closure 34 is pushed down dead bolt 33 and lock housing 32, and described locking closure 34 is screwed on lower fastener 2; Described slide block 4 is spacing at lower fastener surface sliding by the second pin 21 and locking closure 34, described slide block 4 bottoms are connected with one end of described spring 5, the other end of described spring 5 is connected with lock housing 32, and described slide block 4 by spring 5 and the second pin 21 at the interior slip of lower fastener 2 and self-resetting.

Described slide block 4 tops are provided with projection 41, two sides end symmetrical the chute 42 that is stuck in lower fastener 2 sidewalls, and described chute 42 protrudes to the both sides of slide block 4, and the remainder of slide block 4 is all contained in lower fastener 2; On lower fastener 2 top boards directly over projection 41 described in being positioned at, arrange and hold projection 41 through holes that free in and out; Described lower fastener 2 both sides are respectively provided with a slot, and the semicircular structure 13 of described upper button 1 inside wall is provided with for being against the boss 131 on slide block side chute 42.

When described upper button 1 axis and described lower fastener 2 axis overlap, the top edge of described boss 131 is equal with the slot edge of lower fastener 1 end; Described upper button 1 axis and described lower fastener 2 axis angles are greater than 0 while spending, and the slot edge that the edge of described boss 131 exceeds homonymy is against on the chute 42 of slide block 4 lateral end.

Described dead bolt 33 sides are provided with projection 331, and in the time of key operated state, the projection 331 of described dead bolt 33 is vertical with the glide direction of slide block 4; In the time of key locking state, the projection 331 of described dead bolt 33 is against the bottom of described slide block 4.
