Abstract
The utility model discloses a rust -resistant dustproof padlock, include lock body and the U -shaped locking lever made by the metallic iron material, the peripheral cladding of lock body has the protective sheath that the one deck was made by aluminium alloy material. Arrange one end opening one end confined blocking lever chamber in the lock body, the cavity exit end shutoff in blocking lever chamber has an elasticity case, be provided with reset spring between the interior bottom surface in elasticity case and blocking lever chamber. The utility model discloses the protective sheath that the cladding one deck was made by aluminium alloy material outside the lock body to isolated metallic iron material lock body is direct to contact with external environment, thereby is difficult for the oxidation corrosion, guarantees the lock body and normally works. Simultaneously, aluminium alloy material is littleer than a dysmorphism processing degree of difficulty of metallic iron material, so adopt the manufacturing lock body that combines of aluminium alloy material (can expand as non ferrous metal ) and metallic iron material, can reduce the manufacturing of special -shaped lock body greatly to reduction in production cost improves production efficiency, improves the manufacturing accuracy even.
Description
Technical field
The utility model relates to padlock technology field, more particularly a kind of anti-rust dust-proof padlock.
Background technology
Padlock is family ancient, the hugest in the lockset world, can say that other lockset is all multiplied from this class of padlock, derive from.
The structure of padlock such as patent CN200520111332.3 records, and comprises lock body and U-shape sword iron, and described U-shape sword iron coordinates with lock body to have and locks and open two states.Wherein most lock body and U-shape sword iron are made by metallic iron material on the market, because metallic iron is with low cost, hardness is strong, are easy to processing casting.
In the middle of practical application, major part uses the occasion of padlock to be all under the rugged environments such as many dirt, humidity, therefore metallic iron is easy to oxidation corrosion, thus cause U-shape sword iron and lock body to be sticked together, even inner stop ball and guide channel are also sticked together, finally cause difficulty of unblanking, even cannot open.
Prior art lock body is in order to antirust or delay the speed of getting rusty, the large class processing mode of general use two: the external table spray rustproof paint of (1) padlock and specialized paint, the integrated environment of the chemical substances such as benzene contained by paint to air, operating personnel and periphery has more serious pollution.(2) carry out water power plating to irony lock body, the chemicals such as hydride used during electroplating processes and nitric acid all have severe contamination to water source, soil, air.
Utility model content
The purpose of this utility model be to overcome prior art by metallic iron material make lock body long term exposure outside easily oxidation corrosion and causing to unblank the defect that difficulty even cannot open; there is provided a kind of structure simply novel; the not oxidized corrosion under the rugged environments such as many dirt, humidity of protection metallic iron material lock body, ensures the anti-rust dust-proof padlock that lock body normally works.
In order to reach above object, the utility model is achieved through the following technical solutions: a kind of anti-rust dust-proof padlock, comprise the lock body and U-shape sword iron be made up of metallic iron material, being arranged in parallel in described lock body three is all trip(ping) lever chambeies that one end open one end is closed, lock core cavity and support bar chamber, the bottom wall of described lock core cavity is respectively arranged with the guide channel being communicated to described trip(ping) lever chamber and support bar chamber to both sides, a stop ball is provided with in each described guide channel, a lock core is provided with in described lock core cavity, be connected with one bottom described lock core to be driven and the spill spin block of rotation by it, described spill spin block is provided with and can be right against both sides guide channel a pair in its rotary course and allows that described stop ball is with the groove of unblanking of borrow, described U-shape sword iron comprises the trip(ping) lever stretched in described trip(ping) lever chamber and the support bar stretched in described support bar chamber further, the free end sidewall of described trip(ping) lever and support bar is provided with and stops with corresponding separately the locking groove that ball matches, the internal face in described support bar chamber is right against described guide channel and is provided with an elastic force snap close, the free end sidewall of described support bar is also provided with below described locking groove the locking annular groove that a circle matches with described elastic force snap close, power assistant spring is provided with between the free end face of described support bar and the inner bottom surface in support bar chamber, it is characterized in that, the periphery of described lock body is coated with the protective sleeve that one deck is made up of aluminum alloy materials.
The protective sleeve that the utility model is made up of aluminum alloy materials at lock body outer cladding one deck, thus isolated metallic iron material lock body directly contacts with external environment, thus not easily oxidation corrosion, guarantee lock body normally works.
Aluminum alloy materials is less than the shaped piece difficulty of processing of metallic iron material, so adopt the combination of aluminum alloy materials (can non-ferrous metal be expanded as) and metallic iron material to manufacture lock body, greatly can reduce the processing and manufacturing of special-shaped lock body, thus reduction cost of production, enhance productivity, even improve the accuracy of manufacture.
The utility model is multiple not oxidizable to adopting during lock body antirust treatment; the alloy got rusty wraps up one deck alloy material (i.e. protective sleeve) with penetrating the mode that cast packet wraps up in iron surface of lock body at high temperature under high pressure; alloy material is combined closely with iron lock body; surface of lock body to be graded isolation with air water; reach antirust object; such product is not only environmental protection and efficiency is high in process of production, and cost is low.
As preferably, described lock body is provided with a main oil groove, described main oil groove is communicated with two oil grooves, and described in every bar, an oil groove is communicated with guide channel described in respectively, and the port of export filling of described main oil groove at described protective sleeve place has a silica gel plug.
Although the outer protection being with protective sleeve; as long as but there is hole to design; be positioned at inner stop ball and just easily oxidation reaction occur; although stop in the middle of assembling that club adds lubrication oil to ensure that it is not oxidized and reduce slip resistance; but lubrication oil can dryly evaporate in the course of time; so the utility model design adds oil groove, to ensure to continue to add lubrication oil in the future.
As preferably, the cavity outlet end shutoff in trip(ping) lever chamber has an elastic force spool, is provided with back-moving spring between described elastic force spool and the inner bottom surface in trip(ping) lever chamber.
In daily life, under our lock body opens situation, some foreign matter can be fallen in the middle of trip(ping) lever chamber, result in blockage under serious conditions, not easily clear, thus cause trip(ping) lever normally to insert, cannot lock, so increase elastic force spool, when not affecting trip(ping) lever and normally inserting locking, stop that foreign matter is in outward.
Beneficial effect: the protective sleeve that (1) the utility model is made up of aluminum alloy materials at lock body outer cladding one deck, thus isolated metallic iron material lock body directly contacts with external environment, thus not easily oxidation corrosion, guarantee lock body normally works.
(2) aluminum alloy materials is less than the shaped piece difficulty of processing of metallic iron material, so adopt the combination of aluminum alloy materials (can non-ferrous metal be expanded as) and metallic iron material to manufacture lock body, greatly can reduce the processing and manufacturing of special-shaped lock body, thus reduction cost of production, enhance productivity, even improve the accuracy of manufacture.
