Description

Built-in handle

Technical field

The present invention relates to a kind of grip structure more particularly to a kind of built-in handles.

Background technique

Lock is being widely used with office at home, in recent years, with the rapid development of electronic technology, traditional lockset Production earth-shaking change has occurred, modern electronic technology is combined with mechanical technique, produce it is large quantities of such as acoustic control locks, Magnetic control lock, coded lock, remote-controlled lock, the advanced electronic lock such as Fingerprint Lock.The style of lockset is also very much, and people chase after the installation of lockset It asks convenient, and pursues better security performance.But the structure of lockset currently on the market is not ideal enough.Most structure It is all that shank of the key and lock core are separately positioned, it is high for the installation requirement of lockset, and locking mode is single, fixing is weak.In addition for The protection of the keyhole of lock core is weak, keyhole often in dust or other foreign matters from being blocked, and lockset is failed.

It would therefore be highly desirable to solve the above problems.

Summary of the invention

Goal of the invention: the object of the present invention is to provide it is a kind of by lock core be embedded in handle in, compact-sized and good dustproof effect Built-in handle.

Technical solution: the invention discloses a kind of built-in handle, including handle housing and to be located at the handle shell intracorporal Handle lock core is equipped with dustproof construction at the keyhole on the handle housing shell, corresponding to handle lock core；The handle lock core It is lock onto handle housing by skewback.

Wherein, the skewback has the cambered surface being in contact with handle inner wall and the inclined-plane being in contact with lock body outer wall, this is tiltedly In the cavity that block is formed between handle housing and handle lock core, and fixed skewback is squeezed in the cavity by screw.

Preferably, the handle housing is spliced by symmetrical shell half, which is machined piece.

A kind of welding procedure of handle housing, include the following steps: to prepare using process for machining two it is symmetrical Half shell；Two half shells are combined in together, and are fixed using universal fixturing；By gas shielded arc welding along two half shells Surrounding lap welding is carried out outside splicing line；Polishing equating is whole after weldering is full.

Further, the dust-proof hole for placing dustproof construction is offered in the handle housing.

Preferably, the dustproof construction includes the anti-dust seat being embedded in dust-proof hole, dustproof sheet, dust-proof bobbin and torsional spring, institute Anti-dust seat is stated to be fixed in dust-proof hole by dust-proof mounting；The dustproof sheet is arranged in anti-dust seat by dust-proof bobbin, can be with Dust-proof bobbin rotation, the one end of torsional spring are connected in anti-dust seat, and the other end is connected on dustproof sheet, for resetting dustproof sheet.

Furthermore the dustproof construction further includes nut cap, which is located on the outside of dustproof sheet, covers the dustproof sheet.

Further, it is provided with inside groove in the anti-dust seat, steel ball and spring is equipped in the inside groove, the steel ball is supported by spring Firmly dust-proof mounting.

Preferably, the dustproof construction and anti-dust seat are provided with the spring collar for sealing.

Further, the handle anti-dust seat, dustproof sheet, dust-proof mounting, dust-proof bobbin and nut cap are machined piece.

The utility model has the advantages that compared with prior art, remarkable advantage of the invention is: the built-in handle will by skewback first Handle lock core and handle housing locking, the locking mode is simpler, efficient and reliable, enhances the safety of handle lock core, makes Structure is more compact and beautiful, saves manufacturing cost；Secondly dustproof construction protect the keyhole in lock core from dust or other The damage of foreign matter ensures the service performance of handle lock core, extends the service life of handle lock core；Furthermore the handle housing uses Two symmetrical half shells are welded, and welding procedure is reliable, so that handle housing is had excellent performance, scale easy to produce and streamlined Operation extends product service life, reduces production cost；Then built-in handle enhances the use feeling of user, facilitates use Family uses；There are also the handle housing of built-in handle, anti-dust seat, dustproof sheet, dust-proof mounting, dust-proof bobbin and nut caps in the present invention It is all made of machining, so that handle has higher wearability, corrosion resistance and weatherability, under compared with harsh climate environment still It can work normally；Finally release region is arranged on handle the built-in handle makes release region very clear, increases Unlock experience sense, it is whole to promote product quality, while by handle module, scale easy to produce and part replacement.

Specific embodiment

Technical solution of the present invention is described further with reference to the accompanying drawing.

As depicted in figs. 1 and 2, the invention discloses a kind of built-in handle, including it is handle housing 1, handle lock core 2, anti- Dirt structure 3 and skewback 4.As shown in Figure 5 and Figure 6, handle lock core 2 is located in the handle housing 1, and lock onto handle by skewback 4 In hand shell 1, the skewback 4 has the cambered surface 5 being in contact with handle inner wall and the inclined-plane 6 being in contact with lock body outer wall, this is tiltedly In the cavity that block 4 is formed between handle housing 4 and handle lock core 2, and fixed skewback 4 is squeezed in the cavity by screw 7 It is interior.The locking mode is simpler, efficient and reliable, enhances the safety of handle lock core.

Handle housing 1 of the invention is spliced by symmetrical shell half 8, which is machined piece.It is a kind of The welding procedure of handle housing includes the following steps: to prepare two symmetrical half shells 8 using process for machining；By two A half shell 8 is combined in together, and is fixed using universal fixturing；Through gas shielded arc welding outside the splicing line of two half shells 8 Side carries out surrounding lap welding and forms weld seam 9；Polishing equating is whole after weldering is fully welded seam 9, as shown in Figure 3 and Figure 4.

On above-mentioned 1 shell of handle housing, dustproof construction 3 is equipped at the outside keyhole corresponding to handle lock core 2.Handle shell The dust-proof hole for placing dustproof construction 3 is offered on body 1.As shown in figure 8, dustproof construction 3 includes being embedded in dust-proof hole to prevent Dirt seat 10, dustproof sheet 11, dust-proof bobbin 13, torsional spring 14 and nut cap 15, the anti-dust seat 10 are fixed on anti-by dust-proof mounting 12 In dirt hole；The dustproof sheet 11 is arranged in anti-dust seat 10 by dust-proof bobbin 13, can rotate with dust-proof bobbin 13, the torsional spring 14 one end are connected in anti-dust seat 10, and the other end is connected on dustproof sheet 11, for resetting dustproof sheet 11.The nut cap 15 is located at anti- 11 outside of dirt piece, covers the dustproof sheet 11.It is provided with inside groove in anti-dust seat 10, steel ball 16 and spring 17 are equipped in the inside groove, it is described Steel ball 16 resists dust-proof mounting 12 by spring 17.Dustproof construction 10 and dust-proof mounting 12 are equipped with the spring collar for sealing 18。

Wherein, handle housing 1, anti-dust seat 10, dustproof sheet 11, dust-proof mounting 12, dust-proof bobbin 13 and nut cap 15 are machine Workpiece.It is made up compared to traditional of powder alloy material punching press, with hardness is high, intensity is big, wearability is good, friction resistance The features such as power is small, long service life greatly enhances the overall performance of built-in handle, improves built-in handle Weatherability makes it that different climatic conditions, high reliablity can be used, even if can still work normally under more harsh climate.
