[0034] The universal extension portion 12a is connected to the lock portion 11 and extends along the extension direction D2 to form a polygonal rod structure, where, the extension direction D2 will not be parallel to the arrangement direction D1. In this embodiment, the universal extension portion 12a further includes an extension body 121a. As shown in the figure, the extension body 121a is the quadrangular prism structure, also called the rectangular body structure, and the extension body 121a is formed with a fixing groove H2.

[0035] Next, please refer to FIG. 9, FIG. 9 is a perspective view showing a universal adaptor for door handle provided by a third embodiment of the present disclosure. As shown in the figure, a universal adaptor 1b is capable of universally applying to multiple types of door handle, and includes a lock portion 11 and a universal extension portion 12b, where, the lock portion 11 is the same with the lock portion 11 of the first embodiment, thus which will not be repeated here.

[0036] The universal extension portion 12b is connected to the lock portion 11 and extended along the extension direction D2 to form a polygonal rod structure, where, the extension direction D2 will not be parallel to the arrangement direction D1. In this embodiment, the universal extension portion 12b further includes an extension body 121b. The extension body 121b is formed with multiple snap grooves T1, T2 (both presented for illustration).

[0037] In this embodiment, the extension body 121b has a first extension plane S1, a second extension plane S2, a third extension plane S3 and a fourth extension plane S4, and the first extension plane S1 is opposite to the second extension plane S2, the third extension plane S3 is opposite to the fourth extension plane S4, and the first extension plane S1 is adjacent to the third extension plane S3 and the fourth extension plane S4. The snap groove T1 is formed on the first extension plane S1, and the snap groove T2 is formed on the second extension plane S2, any of the snap grooves T1 and T2 is not parallel to the extension direction D2. In this embodiment, each one of the snap grooves T1 and T2 extends along a first direction D3. And providing the snap grooves T1, T2 on the extension body 121b can be regarded as surface roughening treatment.

[0038] At last, please refer to FIG. 5, FIG. 9 and FIG. 10, FIG. 10 is a schematic diagram showing a using state of a universal adaptor for door handle of the present disclosure. As shown in the figure, the universal adaptor 1b of the third embodiment will be taken as an example for explanation in the following, similarly, which can also be applied in the first embodiment and the second embodiment.

[0039] The universal adaptor 1b is used to be universally assembled in a polygonal assembling groove of one of multiple types of handles, accompanying drawings depict three handles PA1a, PA1b, PA1c with different appearances for illustration, where, handles PAla, PA1b are the handles PAla, PA1b in FIG. 1 and FIG. 3.

[0040] A catching-type fit relationship will form between the polygonal rod structure of the universal extension portion 12b and the polygonal assembling grooves Ta, Tb, Tc of the handles PA1a, PA1b, PA1c. The catching-type fit relationship indicates that the universal extension portion 12b can be operatively snap-fixed to the polygonal assembling grooves Ta, Tb, Tc, and form a catching state, so as to be connected with the handles PA1a, PA1b, PA1c; can also be operatively removed from the polygonal assembling grooves Ta, Tb, Tc under a separation state, which does not indicate that the structure of the universal extension portion 12b needs to be totally the same with the structure of the polygonal assembling grooves Ta, Tb, Tc, some tolerance can be allowed to both of them as long as that the universal extension portion 12b can be snapped into the inside of the polygonal assembling grooves Ta, Tb, Tc and be connected with the handles PA1a, PA1b, PA1c, and can be removed from the polygonal assembling grooves Ta, Tb, Tc all comply with the catching-type fit relationship.

[0041] The snap grooves T1, T2 formed on the universal extension portion 12b will be more facilitate for snapping with the polygonal assembling grooves Ta, Tb, Tc, however, the universal extension portion 12 can also be snapped with the polygonal assembling grooves Ta, Tb, Tc by using the structure itself, even the universal extension portion 12 (presented in FIG. 7) in the first embodiment is not formed with the snap grooves T1, T2. In addition, the fixing groove H2 (presented in FIG. 8) formed on the universal extension portion 12a (presented in FIG. 8) of the second embodiment can correspond to a fixing pin of the handles PA1a, PA1b, PA1c respectively, the fixing pin can be located in the polygonal assembling grooves Ta, Tb, Tc, or can penetrate into the polygonal assembling grooves Ta, Tb, Tc from the outside. For example, the circular line on the above of the handle PA1b can be regarded as that the fixing pin is penetrated from the outside to the polygonal assembling groove Tb, then is inserted into the fixing groove H2, so that the universal extension portion 12a is snapped with the handle PA1b.

[0042] The lock hole H1 of the lock portion 11 will correspond to the panel lock L as shown in FIG. 5, so it can be locked to the lock pin P. Therefore, after the universal extension portion 12b is universally assembled in the polygonal assembling grooves Ta, Tb, Tc of the handles PA1a, PA1b, PA1c, panel-like lock handles similar with the panel lock handles PA2a, PA2b in FIG. 4 and FIG. 6 will be formed as a whole respectively, so as to make the handles PA1a, PA1b, PA1c be locked to the panel locks L respectively. It should be noted that, the panel-like lock handle refers to a handle which has the same functions with the handles PA2a, PA2b and can be locked to the panel lock L, but does not need to be manufactured by integral molding like the panel lock handles PA2a, PA2b.

[0043] Similarly, both the universal adaptor 1 (presented in FIG. 7) in the first embodiment and the universal adaptor 1a (presented in FIG. 8) in the second embodiment can also achieve the same functions and effects, so details will not be repeated.

[0044] As a summary, the universal adaptor for door handle provided by the present disclosure is universally assembled in the polygonal assembling groove of one of multiple types of handles by using the lock portion and the universal extension portion, so as to make the above-mentioned handle form a panel-like lock handle and be locked to the panel lock. Compared with the prior art, the present disclosure can be universally assembled in common handles with polygonal assembling grooves, achieve the common functions and effects, and enable the above-mentioned handles to form panel-like lock handles and are locked to panel locks, thereby resolving the problem that the handles with polygonal assembling grooves cannot be locked to the panel locks in the prior art, and the problems that different appearances require correspondingly different molds and different development costs, small quantity demanded makes the development costs a burden, overstock and backlog materials caused by minimum production requirements and various problems raised from those, all of which are caused by the panel lock handles are manufactured by integral molding.

[0045] Through the detailed description of the above-mentioned preferred embodiments, it is hoped that the characteristics and spirit of the present disclosure can be described more clearly, rather than limiting the scope of the present disclosure by the preferred embodiments disclosed above. On the contrary, the purpose is to cover various modifications and equivalent arrangements within the scope of the appended claims to be claimed by the present disclosure.
