Description

Security door combination anti-picking device

Technical field

The utility model relates to a kind of security door, the combination anti-picking device that uses on particularly a kind of security door.

Background technology

Along with the progress of development of times and society, China's per capita income and living standard have obtained further raising, and broad masses have gone up the life of living and working in peace and contentment basically excessively; Steal his person property but always there is the sub-fraction unprincipled fellow to enter the room in the society, cause personal safety and property to can not get ensureing by forcing open the door.In order to improve the pick-proof performance of security door, many manufacturers have all constantly carried out corresponding improvement in the pick-proof measure of security door, and the one, on door leaf, set up the pick-proof limit, behind bender bending gummed, the safety groove that matches with door leaf pick-proof limit is set up in extrusion modling again on the doorframe; The 2nd, further improve the anti-skill of theftproof lock and open performance and pick-proof performance; But the phenomenon that security door is prized still happens occasionally, and therefore, developing the good security door of a kind of pick-proof performance is extremely urgent problem.For this reason, many manufacturers and knowledgeable people develop and develop, but do not have better products to emerge so far as yet.

Summary of the invention

For overcoming existing security door above shortcomings, the purpose of this utility model provides a kind of security door simple and reasonable, easy for operation, that pick-proof is effective and makes up anti-picking device.

The technical scheme that its technical problem that solves the utility model adopts, it comprises doorframe, door leaf, theftproof lock, door leaf is hinged on the doorframe, theftproof lock is installed on the door leaf, doorframe is provided with and the corresponding lockhole of locking bolt, described doorframe is provided with the first and second pick-proof draw-in grooves, door leaf is provided with the first and second pick-proof crochets that match with the first and second pick-proof draw-in grooves, be fixed with the left-hand thread plate corresponding on the door leaf with lock body, doorframe is provided with the left-hand thread plate jack that is complementary with the left-hand thread plate, and the left-hand thread plate is provided with and the corresponding left-hand thread plate of locking bolt lockhole.

Light in order to lock, the lockhole of described doorframe is provided with the locking bolt prerotation vane.

In order to improve the anti-drilling performance of lock core, be provided with lock core drilling-preventing cover adjustment sheet and lock core drilling-preventing cover on the lock core of described theftproof lock successively.

For the ease of producing, improve the intensity of product, bending extrusion modling after the external door panel of door leaf is inserted in the described first pick-proof crochet by the internal hilar plate of door leaf, and the second pick-proof crochet is by a bending extrusion modling of internal hilar plate of door leaf.

After adopting said structure, the utility model has following advantage and effect: security door has obtained multiple protective, and first pipe protection is cooperated with the first and second pick-proof draw-in grooves on the doorframe by the first and second pick-proof crochets on the door leaf; Second pipe protection is that the left-hand thread plate on the door leaf inserts in the left-hand thread plate jack on the doorframe, and locking bolt passes to insert behind the doorframe lockhole again and pins the left-hand thread plate on the left-hand thread plate lockhole; The 3rd pipe protection be lock core pass door leaf internal hilar plate, antitheft lock and lock core drilling-preventing cover adjustment sheet after, penetrate the lock core drilling-preventing cover again; Thereby the omnibearing whole pick-proof performance that has improved security door.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Shown in Figure 1, concrete enforcement case for a kind of security door combination of the utility model anti-picking device, it comprises doorframe 1, door leaf 2, theftproof lock 3, door leaf 2 is hinged on the doorframe 1, theftproof lock 3 is installed on the door leaf 2, doorframe 1 is provided with and locking bolt 14 corresponding lockholes 15, described doorframe 1 is provided with the first and second pick-proof draw-in grooves 6,7, door leaf 2 is provided with and the first and second pick-proof draw-in grooves 6, the 7 first and second pick-proof crochets 8 that match, 9, bending extrusion modling after the external door panel of door leaf is inserted in the described first pick-proof crochet 8 by the internal hilar plate of door leaf 2, the second pick-proof crochet 9 is by a bending extrusion modling of internal hilar plate of door leaf 2, the first and second pick-proof crochets 8, the 9 corresponding and first and second pick-proof draw-in grooves 6,7 cooperate the pick-proof effect of playing.Be fixed with the left-hand thread plate 12 corresponding with lock body on the door leaf 2, doorframe 1 is provided with the left-hand thread plate jack 13 that is complementary with left-hand thread plate 12, and left-hand thread plate 12 is provided with and locking bolt 14 corresponding left-hand thread plate lockholes 11.The lockhole 15 of described doorframe 1 is provided with locking bolt prerotation vane 10.Be provided with lock core drilling-preventing cover adjustment sheet 5 and lock core drilling-preventing cover 4 on the lock core of described theftproof lock 3 successively, lock core drilling-preventing cover adjustment sheet 5 plays the effect of regulating lock core drilling-preventing cover 4 height.

When security door was locked, in the left-hand thread plate jack 13 that the left-hand thread plate 12 on the door leaf 2 inserts on the doorframe 1, the locking bolt 14 of theftproof lock 3 inserted pinning left-hand thread plate 12 on the left-hand thread plate lockhole 11 after passing lockhole 15 again.After adopting said structure, the robber wants to pry open theftproof lock 3, just is subjected to stopping of the first and second pick-proof crochets 8,9 and left-hand thread plate 12, and pry just can't be stretched and theftproof lock 3 at all; Even the robber wants to bore or prize the lock core of theftproof lock 3, the lock core drilling-preventing cover 4 that also can be subjected to door leaf 2 theftproof locks 3 outsides hinders, and makes the robber feel simply helpless, thus the comprehensive pick-proof performance that has improved security door.
