Background technology

Number of patent application 200710069808.5 " strongbox safety bolt ", though a kind of safety latch also is provided, the part of its formation is also more, makes trouble, the cost of manufacture height.

The patent No. 200820084799.7 " a kind of inverted hook type safe door ", a kind of alignment pin and gathering sill mating reaction of being buckled by door bolt is provided, when its during at lock-out state, the hook portion of door bolt button is the shelves post in intrinsic deflection catches on knocker, make the door bolt head be difficult for from the door bolt hole, breaking away from the pick-proof effect of playing, but this inverted hook type door bolt button, form by door bolt head, door bolt button, alignment pin, the guide strip that has a gathering sill, two door bolt buttons are installed in the door bolt head, each door bolt button also will be used the superimposed composition of cramp, door bolt also is equipped with bumping post in the hole, and its structure is simple not enough.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of bin latch hook is provided, strongbox, safe deposit box, file cabinet, silver cabinet, the supporting use of strong-room door with various different structures, improve the pick-proof ability and the safety in utilization of safe, and this latch hook is simple in structure, part is few, easy making.

The technical scheme in the invention for solving the above technical problem is: the bin latch hook, comprise the door bolt hole on the casing, be connected the tapered end on the chamber door, be connected the connecting rod on the slide plate, described tapered end is made up of one or more lock ring, and described connecting rod is made up of one or more locking bar, and connecting rod and tapered end connect into rotating one, tapered end cooperates with door bolt hole on the casing doorframe, and described locking bar is a foldable shape rod, and bending angle is α.

Described tapered end is made up of two lock rings of upper and lower symmetry, and an end of upper and lower lock ring is a semicircular arc, and the connecting rod pin-and-hole is arranged above, the fixed rotating shaft hole, and the other end is an arc, is made of one-piece parts.

Described connecting rod is made up of upper and lower two locking bars of symmetry, and positioning and fixing bar hole, connecting rod pin-and-hole are arranged respectively on the two ends of upper and lower locking bar, and upper and lower locking bar is bent into foldable shape rod by steel plate, and bending angle α is 90～170 degree.

Described upper and lower locking bar and upper and lower lock ring connect into rotating one with the connecting rod pin-and-hole that link pin passes on upper and lower locking bar, the upper and lower lock ring.

Upper and lower door bolt hole is arranged on the doorframe of described casing, and upper and lower lock ring cooperates with upper and lower door bolt hole on the doorframe.

Compared with prior art, advantage of the present utility model is: this latch hook is simple in structure, part is few, only form by the lock ring of a secondary upper and lower symmetry and the locking bar of a secondary upper and lower symmetry, and connecting rod and tapered end connect into rotating one with the positioning and fixing bar, the fixed rotating shaft that are fixed on slide plate and the chamber door respectively, tapered end, connecting rod all are integrally-built part simultaneously, easily make processing, do not have the requirement of cooperation, easily assembling, low cost of manufacture.Increased by a secondary bolt of strengthening for it during with supporting use such as safe, safe deposit box, two lock rings just rotate along link pin automatically after tapered end enters the door bolt hole, two lock rings are just repeatedly embraced or obvolvent becomes a firm obturator then, not only strengthen tamper-resistant function but also safe in utilization, also saved the bumping post in the door bolt hole.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Tapered end is made up of two lock rings of upper and lower symmetry, and an end of upper and

lower lock ring

5,1 is a semicircular arc, and the connecting rod pin-and-hole is arranged above, the fixed rotating shaft hole, and the other end is an arc, is made of one-piece parts.

Connecting rod is made up of upper and lower two locking bars of symmetry, and positioning and fixing bar hole, connecting rod pin-and-hole are arranged respectively on the two ends of upper and

lower locking bar

4,2, and upper and lower locking bar is bent into foldable shape rod by steel plate, and bending angle α is 90～170 degree on it.

The connecting rod pin-and-hole that two link pins 3 pass respectively on upper and

lower locking bar

4,2 and the upper and

lower lock ring

5,1 connects into rotating one, constitutes the bin latch hook, as shown in Figure 1.

Tapered end is connected on the fixed rotating shaft 6 on the chamber door 9 with the fixed rotating shaft hole on it, and upper and

lower lock ring

5,1 can both rotate around fixed rotating shaft 6, and upper and

lower locking bar

4,2 utilizes the positioning and fixing bar hole on it to be connected on the positioning and fixing bar 7 on the slide plate 8.Upper and

lower locking bar

4,2 can rotate around positioning and fixing bar 7 again, as shown in Figure 2.

If will close strongbox, by handle on the chamber door or knob chamber door 9 and slide plate 8 are moved to doorframe 10 directions of casing, at this moment the upper and lower locking bar on the slide plate also moves to the doorframe direction, and with link pin 3 clockwise, counter-clockwise direction rotations, also drive simultaneously upper and

lower lock ring

5,1 synchronously along fixed rotating shaft 6 clockwise, counter-clockwise direction rotations, and insert in the upper and lower

door bolt hole

12,11 on the doorframe 10, repeatedly embrace or obvolvent becomes enclosed shape that chamber door 9 is pinned, as shown in Figure 4.

If will open strongbox, at this moment rotate handle or knob on the chamber door 9, making chamber door 9 and slide plate 8 leave doorframe 10 directions moves, then 4,2 clockwise, the counter-clockwise direction rotations of the upper and lower locking bar on the slide plate 8, and also inhour, clockwise direction rotate to drive upper and

lower lock ring

5,1 synchronously, withdraw from the upper and lower

door bolt hole

12,11 from doorframe 10, chamber door 9 is opened, as shown in Figure 5.

This latch hook can be installed in the upper and lower, middle of chamber door 9 or other position use as required, one or more latch hooks can be installed use, and is installed in as shown in Figure 3 on the centre position of chamber door.

Also can install as required by a lock ring constitute tapered end, locking bar constitute connecting rod and and the casing doorframe on a door bolt hole be used, concrete action is not described in detail as mentioned above.
