DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] See attached Figure 1 To the attached Figure 4As shown, this embodiment provides a travel conversion charger 100, which includes a shell 1, a first pin assembly 3 and at least one second pin assembly 4, the first pin assembly 3 and the second pin assembly 4 are installed in the inner cavity of the shell 1, and the first pin assembly 3 and the second pin assembly 4 are respectively installed at opposite ends of the inner cavity of the shell 1.

[0029] Combined with reference to Figure 4 To the attached Figure 7 As shown, in this embodiment, the first pin assembly 3 is installed at the right position in the inner cavity of the shell 1. The first pin assembly 3 includes a first pin 31, a first pressing pusher 33 and a guide sleeve 32. The guide sleeve 32 is fixedly installed on a pair of guide columns 35 in the inner cavity of the shell 1. The pair of guide columns 35 are vertically installed in the inner cavity of the shell 1. A pair of ear pieces 322 are provided at both ends of one side of the outer surface of the guide sleeve 32. The ear pieces 322 are formed with mounting holes. The guide sleeve 32 is fixedly installed on the pair of guide columns 35 through the ear pieces 322 thereon.

[0030] Continue to refer to the attached Figure 6 and attached Figure 7 As shown, the bottom end of the guide sleeve 32 is provided with a guide hole 321 for the vertical lifting movement of the first pin 31. The first pin 31 is vertically installed in the guide hole 321 and the two form a vertical sliding connection. The top end of the first pin 31 is clamped and fixedly connected with the first pressing member 33. Figure 5 and attached Figure 6 As shown, a slot 311 is formed in the middle of the first pressing and pushing member 33, and a pair of buckles extending upward are formed at the top of the first pin 31. When the first pressing and pushing member 33 and the first pin 31 are installed, the pair of buckles at the top of the first pin 31 are inserted into the slot 311 of the first pressing and pushing member 33 so that the buckles are tightly clamped in the slot 311. In this way, the first pressing and pushing member 33 and the first pin 31 are fixed together. Figure 1 and attached Figure 2 As shown, at the same time, a first guide groove 11 for sliding the first pressing push member 33 is formed on the outer end surface of the housing 1. Figure 5 and attached Figure 6 As shown, in order to ensure that the first pin 31 stops moving after reaching a preset extension length during the process of outward extension, the first pin assembly 3 also includes a first limiting assembly 34 for limiting the length of the first pin 31 extending from the housing 1. Specifically, the first limiting assembly 34 includes a first clamping piece 341 provided on the outer end surface of the first pin 31 and a first clamping groove 342 provided on the outer surface of the guide sleeve 32 for clamping with the first clamping piece 341.

[0031] Refer to the attached Figure 2As shown, a first socket 13 is formed at the end surface of the shell 1 at a position corresponding to the first pin 31. The hole shape of the first socket 13 matches the shape of the first pin 31, so that when the first pressing push member 33 drives the first pin 31 to slide outward, the first pin 31 will extend outward from the first socket 13.

[0032] Combined with reference to Figure 4 , Attachment Figure 8 And attached Figure 9 As shown, in this embodiment, the second pin assembly 4 is a pair, disposed on the other side of the inner cavity of the housing 1, to the left of the first pin assembly 3. In this embodiment, the second pin assembly 4 comprises a UK standard and a US standard, respectively, while the first pin assembly 3 comprises a European standard. The first and second pin assemblies 3 and 4 are installed independently. Therefore, whether the first or second pin assembly 3 or 4 is installed first during assembly does not affect the installation of the latter pin assembly. This avoids the problem with existing travel power socket adapters where the later pin assembly process can affect the stability of the earlier assembled pins.

[0033] Combined with reference to Figure 1 To the attached Figure 3 And attached Figure 8 and attached Figure 9 As shown, in this embodiment, the second pin assembly 4 includes a guide assembly 43, a second pin 42 and a second pressing pusher 41. The guide assembly 43 is fixedly installed in the inner cavity of the shell 1. The top of the second pin 42 is clamped and fixedly connected to the second pressing pusher 41. The second pin 42 is slidably installed on the guide assembly 43 and forms a vertical sliding connection with it. A second guide groove 12 is formed on the shell 1, which vertically slides with the second pressing pusher 41. A second socket 14 for the second pin 42 to be movably extended is formed at the position corresponding to the second pin 42 on the shell 1.

[0034] Refer to the attached Figure 8 and attached Figure 9 As shown, similarly, to ensure that the second pin 42 stops moving after reaching a predetermined extension length during its outward extension process driven by the second pressing member 41, a second limiting assembly 44 is provided between the second pin 42 and the housing 1 to limit the extension length of the second pin 42 from the housing 1. Specifically, the second limiting assembly 44 includes a second clamping piece 441 fixedly disposed on one side of the outer side of the second pin 42 and a second retaining groove 442 fixedly disposed on the bottom end surface of the housing 1 for lockingly engaging with the second clamping piece 441.

[0035] Refer to the attached Figure 1As shown, in order to facilitate the operator to carry the travel conversion charger, a handle 2 for easy grasping is also installed on one end surface of the shell 1.

[0036] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
