Accompanying drawing 2 is the front view of burglarproof sleeve lock.Referring to accompanying drawing 2.Lock body 7 is I-shaped frid, and the centre is a rectangular base plate, has the rectangle deckle board up and down.Have the groove that can supply locking bolt 8 two ends to move up and down up and down on the deckle board.Locking bolt 8 usefulness steel plates are made, and main body is a rectangle, and the groove that upper and lower side can have on the deckle board up and down of lock body 7 moves up and down.The top of locking bolt 8 has the guide vane end stop perpendicular to locking bolt 8, the bottom also have perpendicular to locking bolt 8 the spring plate.The two ends of spring 10 collude respectively on above the lock body 7 deckle board and locking bolt 8 below the spring plate on.Spoon stem stem 9 vertically is welded on lock body 7 and the base plate that deckle board is vertical up and down, is welded on from 7 centimetres of last deckle boards, from the position of 4 centimetres of left side bearings.The thick 3 millimeters steel plate of lock body 7 usefulness of embodiment is made the I-shaped frid, and base plate is high 14 centimetres, wide 10 centimetres rectangle, and last deckle board and lower frame plate all are wide 4 centimetres, high 10 centimetres rectangle.The steel plate that locking bolt 2 usefulness are thick 3 millimeters is made, and main body is high 18 centimetres, wide 3 centimetres rectangle, 4 centimetres away from upper end be the guide vane end stops that are welded with perpendicular to locking bolt 8 main body rectangles in top, and guide vane end stop is wide 2 centimetres, high by 1.6 centimetres rectangle.4 centimetres away from bottom be the spring plates that are welded with perpendicular to locking bolt 8 main body rectangles in bottom, the spring plate is wide 1 centimetre, high 1 centimetre rectangle.Guide vane end stop and spring plate all use thick 3 centimetres steel plate to make.Lock core column 9 is high 4 centimetres, makes with the round steel of 12 millimeters of diameters.The steel wire that spring 10 usefulness diameters are 0.5 millimeter is made, and the original length when not drawing back is 9 centimetres.
Accompanying drawing 3 is rearviews of the utility model embodiment.Can see the situation of lock body 7, locking bolt 8, spring 4 from this figure.
Accompanying drawing 4 is left views of the utility model embodiment.The middle and upper part that can see locking bolt 8 from this figure also is welded with compression leg 11, and compression leg 11 is high 1 centimetre, makes with the round steel of 0.6 centimetre of diameter, is welded on be 9 centimetres away from upper end of locking bolt 8, from the position of 1 centimetre of right side bearing.
Accompanying drawing 5 is right views of the utility model embodiment.Can see the relative position of lock body 7, locking bolt 8, spoon stem stem 9, spring 10, compression leg 11 from this figure.
Accompanying drawing 6 is vertical views of the utility model embodiment.The top that can see locking bolt 8 from this figure can be mobile at the upper side frame of lock body 7.The upper side frame of lock body 7 has high 3.5 millimeters, wide 3.5 centimetres rectangular channel, and the right side bearing of groove is from 1.5 centimetres of the right side bearings of upper side frame, laterally opens on the horizontal center line of frame on top.
Accompanying drawing 7 is upward views of the utility model embodiment.The bottom that can see locking bolt 8 from this figure can be mobile at the lower frame of lock body 7.The lower frame of lock body 7 has high 3.5 millimeters, wide 3.5 centimetres rectangular channel, and the right side bearing of groove is laterally opened on the horizontal center line of lower frame from 1.5 centimetres of the right side bearings of lower frame.
Key of the present utility model is the sleeve key, have hand lever 12, link hand lever 12 sleeve 14, be fixed in the locking bolt card article 13 that locking bolt 8 will be able to be inserted in two parallel to each other and middle intervals that sleeve 14 hold.
Accompanying drawing 8 is front views of the sleeve key of the utility model embodiment.Can see the mutual alignment situation of hand lever 12 and locking bolt card article 13 from this figure.8.5 centimetres of hand lever 12 length are made with 18 millimeters round steel.Locking bolt card article 13 is vertical with hand lever 12.
Accompanying drawing 9 is rearviews of the sleeve key of the utility model embodiment.Can see sleeve 14 and hand lever 12 orthogonal welding from this figure.9 centimetres of sleeve 14 length, with thick 3 millimeters, the steel pipe that diameter is 2 centimetres is made.Locking bolt card article 13 vertically is welded on the head end of sleeve 14.
Accompanying drawing 10 is left views of the sleeve key of the utility model embodiment.Can see the mutual alignment situation of sleeve 14, hand lever 12, locking bolt card article 13 from this figure.Totally two of locking bolt card articles 13, every for long 3 centimetres, wide 6 millimeters rectangle, makes with thick 3 millimeters steel plate.
Accompanying drawing 11 is right views of the sleeve key of the utility model embodiment.From this figure can see sleeve 14, hand lever 12, mutual upright position situation.
Accompanying drawing 12 is vertical views of the sleeve key of the utility model embodiment.Can see the orthogonal situation of sleeve 14, hand lever 12, locking bolt card article 13 from this figure.Article two, locking bolt card article 13 is 5 millimeters at interval.
Accompanying drawing 13 is upward views of the sleeve key of the utility model embodiment.Can see the orthogonal situation of sleeve 14, hand lever 12, locking bolt card article 13 from this figure.Sleeve 14 is orthogonal with hand lever 12, and sleeve 14 is orthogonal again with locking bolt card article 13.
The utility model is to use like this, when the utility model is unblanked, make two locking bolt card articles 13 straight up, the sleeve key is penetrated open keyhole 5, sleeve 14 is inserted in the lock core column 9, turn hand lever 12 is to right rotation then, make two intervals in the locking bolt card article 13 be inserted in the locking bolt 8 and push down compression leg 11, continue to be rotated down, make compression leg 11 move down pulling spring 10 to bottom offset, locking bolt 8 moves down under the pulling of spring 10, be inserted in up to the upper end that makes locking bolt 8 card article 6 parts break away from fully can open the door 2.To be inserted in the sleeve 14 of sleeve key in the lock core column 9 equally at closing time, make two locking bolt card articles 13 earlier straight up, turn hand lever 12 is to right rotation then, make two intervals in the locking bolt card article 13 be inserted in the locking bolt 8 and push down compression leg 11, continue to be rotated down, make compression leg 11 move down pulling spring 10 to bottom offset, locking bolt 8 moves down under the pulling of spring 10, drop to extreme lower position up to the upper end that makes locking bolt 8, unclamp hand lever 12 at last, under the tension force of spring 10, card article 6 inboards that are positioned at door 2 are risen in the upper end of locking bolt 8, with door 2 and casing 1 locking.
Can there be very many various combinations the installation site of the diameter of the thickness of the utility model locking bolt 8, lock core column 9 and compression leg 11, careless one is the sleeve key can not satisfy the interval that can be inserted in lock core column 9, two the locking bolt card articles 13 simultaneously to be inserted in that also thereby can push down compression leg 11 opens lock body in the locking bolt 8, so the utility model has good confidentiality.When the utility model is only used a locking bolt card article 13, can reach application target equally, but confidentiality is less than with two locking bolt card articles 13.
