Detailed Description
Referring to fig. 1 to 9, the present invention discloses a double-layer springless angle blade lock, comprising a lock shell 1, a lock cylinder 2, a spacer 3, an inner row of blades 4, an outer row of blades 5, a lock bolt 6 and a key 7.
The lock housing 1 has a core cavity 11, a plug recess 12 and a primary keyway 13.
The lock cylinder 2 is rotatably inserted in the cylinder chamber 11. In order to facilitate installation and disassembly, a clamp spring groove 14 is formed in the lock shell 1, a step 21 is formed on the lock cylinder 2, the lock cylinder 2 is inserted into the lock cylinder cavity 11, and the clamp spring 15 is arranged on the clamp spring groove 14 and the step 21. The lock cylinder 2 is formed with a blade cavity 22, a lug groove 23 and a latch groove 24.
The inner row of plates 4 is provided with a first keyhole 41, the first keyhole 41 is internally protruded to form a first lock tooth 42, and the side edge of the inner row of plates 4 is provided with a first lock bolt clamping groove 43 and a first lug 44 in the lug groove 23.
The outer sheet 5 is formed with an inner sheet cavity 51 and a second key hole 52, the second key hole 52 is internally protruded to form a second lock tooth 53, and the side edge of the outer sheet 5 is formed with a second lock bolt clamping groove 54 and a second lug 55 in the lug groove 23.
An inner row of sheets 4 is placed in an inner row of sheet cavities 51 of an outer row of sheets 5 to form a set of rows of sheets. A spacer 3 is placed between two adjacent sets of rows of plates, a third keyhole 31 is formed in the spacer 3, and a plurality of sets of rows of plates are received in the row plate cavity 22. For ease of installation positioning, the sides of the spacer 3 form a fifth lug 32 and a third latch catch 33 in the lug well 23.
The lock cylinder 6 is inserted in the lock cylinder groove 24 of the lock cylinder 2, and a lock cylinder return spring 61 is provided between the lock cylinder 6 and the lock cylinder 2. In order to facilitate installation of the latch return spring 61, a spring seat 62 is respectively installed at the front and rear positions in the row slice cavity 22 of the lock cylinder 2, specifically, a fourth lug 65 formed on the side edge of the spring seat 62 is positioned in the lug groove 23 to fix the spring seat 62, a fifth key hole 63 is formed on the spring seat 62, a spring groove 64 is formed on the side edge of the spring seat 62, and the latch return spring 61 is placed in the spring groove 64 and abuts against the latch 6.
The key 7 has a plug 71 insertable into the main key hole 13, the first key hole 41, the second key hole 52, and the third key hole 31, the plug 71 having an arc surface formed thereon, and upper and lower rows of internal teeth 72 formed on the arc surface, the upper and lower rows of internal teeth 72 being engageable with the first lock teeth 42 of the inner row of plates 4 and the second lock teeth 53 of the outer row of plates 5. Specifically, a half arc surface is formed on the inserted link 71, and a double-row serpentine internal tooth flower 72 is formed on the half arc surface, so that the duplication is not easy.
When the locking state or the key is incorrect, the first lock bolt clamping groove 43 and the second lock bolt clamping groove 54 are not aligned with the lock bolt groove 24 in the center, and the lock bolt 6 cannot fall into the first lock bolt clamping groove 43 and the second lock bolt clamping groove 54 to be clamped in the lock bolt groove 12 of the lock shell 1, so that the lock cylinder 2 cannot rotate. When the correct key 7 is inserted, the internal tooth pattern 72 drives the inner row sheet 4 and the outer row sheet 5 to rotate around the central axis of the row sheet cavity 22 of the lock cylinder 2, so that the first lock bolt clamping groove 43 and the second lock bolt clamping groove 54 are aligned with the lock bolt groove 24 in the center, and when the key 7 is further rotated, the lock cylinder 2 can be driven to rotate, the lock bolt 6 is pushed to compress the lock bolt reset spring 61 to withdraw from the lock bolt groove 12 and fall into the first lock bolt clamping groove 43 and the second lock bolt clamping groove 54, and the lock bolt reset spring is separated from the lock bolt groove 12 of the lock case 1, so that the key 7 can drive the lock cylinder 2 to rotate for unlocking.
In order to further improve the safety performance, the side edges of the inner row of sheets 4 and the outer row of sheets 5 are correspondingly provided with anti-poking grooves 45 and 56; the anti-drilling sheet 8 is arranged in the row sheet cavity 22 of the lock cylinder 2 by the main key hole 13 of the lock shell 1, a fourth key hole 81 is formed in the anti-drilling sheet 8 for the insertion rod 71 of the key 7 to pass through, a third lug 82 positioned in the lug groove 23 and a positioning block 83 positioned in the lock bolt groove 24 are formed on the side edge of the anti-drilling sheet 8, and the anti-drilling sheet 8 can play roles in anti-drilling and anti-sawing.
The inner row of sheets 4 and the outer row of sheets 5 form a double-layer structure, the inner row of sheets 4 and the outer row of sheets 5 do not need springs, angle passwords are realized by utilizing the upper row and the lower row of inner teeth 72 on the circular arc surface, the inner row of sheets 4 and the outer row of sheets 5 are extremely difficult to be opened by a technology, the safety performance is high, and the inner row of sheets 4 and the outer row of sheets 5 can be made of stainless steel, so that the inner row of sheets has high strength, wear resistance and corrosion resistance. The number of the row sheets of the invention determines the number of the dental floss, taking 7 groups of row sheets as an example, if the inner row sheets 4 and the outer row sheets 5 have 4 angle changes, and 14 row sheets are arranged in total in 7 groups of row sheets, the dental floss number is 14 times of 4, namely: 2.6 hundred million, if there are 5 kinds of angle changes in the inner row of sheets 4 and the outer row of sheets 5, then the number of teeth is 14 times 5, namely: 60 hundred million. The lock can greatly improve the safety.
Compared with the primary and secondary blade locks, the invention adopts an angle code, the code does not need a spring, the inner row of sheets 4 and the outer row of sheets 5 can be punched and formed, the cost is low, the primary and secondary blade locks adopt a linear code, the code needs a spring, and the primary row of sheets needs powder injection, thereby having high cost.
Compared with an amprence lock, the lock adopts a double-layer password, unlocking does not need to idle, the circular arc surface of the key 7 is snakelike to mill the upper and lower rows of internal teeth 72, the safety is extremely high, the An Bile lock adopts a single-layer password, unlocking needs to idle for a certain angle, and the key 7 is transversely cut and milled with the teeth, so that the safety is poor.
