Description

Lockset for tool box

Technical field

The utility model relates to a kind of lockset for tool box, is used for the case lid of implementation tool case and sealed the fixing between the casing, belongs to five metals manufacturing technology field.

Background technology

At present, the lockset for tool box that is used to lock case lid and casing adopts pad lock structure mostly, and there is following defective in the lockset of this pad lock structure: at first, exposedly suffer wind and weather outside for a long time, easily get rusty fastness, poor reliability; Secondly, prized easily, theftproof performance is poor; Again, obturation effect is poor.

Defective at above-mentioned existence, Chinese invention patent publication number CN1573002A discloses the tool box rotating lock technical scheme by the application of U.S. Reaton Corp., it is that certificate is in U.S. Patent number US6502871 (issue on January 7th, 2003), US6454321 (issue on September 24th, 2002), the existing improvement that can't be applied to the drawback on the strict tool box of instructions for use and propose of US5884948 (issue on March 23rd, 1999), core is the impacting pin by horizontal spreading on the lid in tool box be meshed with locking devicen (cooperation), the key that the lock core member is rotated is able to insert the handle from the front portion of bolt lock mechanism, and the tool box is fastened use locking, to prevent that locking bar from unclamping impacting pin, ensure the locking effect.This scheme has only been paid attention to the solid effect of door bolt of lockset itself, but attaches undue importance to one thing to the neglect of the other to some extent for the obturation effect under lock-out state between case lid and the casing; Owing to only depend on the rotating lock structure as a whole between case lid and the casing, the load of rotating lock often is easy to cause damage greatly; The binding site of whole lockset and casing, case lid (face) is too narrow and small, and stress is concentrated, the anxiety that exists lockset and casing or case lid to be separated and to come off; Overall structure is comparatively complicated.

Chinese patent notice of authorization CN2258219Y, CN2758032Y, CN2705278Y disclose tool box, the tool box fastener structures that name is called lockset for tool box, has buckle structure respectively, though these patented technology schemes are directed to prior art achievement is arranged respectively, for example CN2258219Y utilizes opening/closing so that the push and block body can move freely or locatees of number wheel, with the control panel button could switching effect, control locking, unblank thereby reach, have certain antitheft effect in number wheel check mark mode; And for example the mentality of designing of CN2758032Y and CN2705278Y is roughly similar, and the contacting piece structure has been carried out reasonable improvement.But above-mentioned patent is still all deposited the applicant in four shortcomings mentioned to CN1576002A.

More and more paid close attention to for the case lid in tool box and casing between the two seal under lock-out state, otherwise not only can under stand-by state, make moisture attack instrument in the case, and must extraordinarily severely be protected for the environment of rain, snow, mist and so on by people.In addition, whether people can take off with tool box reliable connection, unlikely branch muchly and use and increase the service life and whether structure is simple, the whether also comparatively concern of convenient, fast aspect of unlatchings/locking for lockset when paying close attention to seal.

Total the above, for the lockset of the various structures on the tool box or claim the exploitation of locker, China domestic enterprise make inquiries and trial person very few, for example above mentioned four pieces of patent documentations also are almost imported goods by the product that the U.S. and TaiWan, China application, especially existing market are seen in respectively.
