DETAILED DESCRIPTION

[0023] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0024] Please refer to Figures 1 to 6 A travel converter comprises a housing 1 and a British standard plug 2 and a European standard plug installed on the housing 1, wherein the British standard plug 2 comprises a first live wire plug 21, a first neutral wire plug 22 and a grounding pin 23, and the European standard plug comprises a European standard sleeve 4 slidably installed on the housing 1 along the Z-axis direction, wherein the first live wire plug 21 and the first neutral wire plug 22 are located on a first side of the European standard sleeve 4, and the grounding pin 23 is located on a second side of the European standard sleeve 4 opposite to the first side; the European standard plug further comprises a European standard push handle 3, a European standard support The European standard bracket 8 and the telescopic component are provided with a second live wire pin 83 and a second neutral wire pin 84, the European standard push handle 3 is connected to the European standard sleeve 4, the European standard bracket 8 can be slidably installed on the European standard sleeve 4, and the telescopic component is connected to the shell 1 and the European standard bracket 8; when the European standard push handle 3 is pushed to drive the European standard sleeve 4 to slide out of the shell 1, the telescopic component drives the European standard bracket 8 to slide in the European standard sleeve 4, so that the second live wire pin 83 and the second neutral wire pin 84 slide out of the European standard sleeve 4.

[0025] From the above description, it can be seen that the beneficial effect of the present invention is that: by arranging the first live wire pin 21 and the first neutral wire pin 22 of the British standard plug 2 on the first side of the European standard sleeve 4, and arranging the grounding pin 23 on the second side of the European standard sleeve 4, the space occupied by the British standard plug 2 on the shell 1 overlaps with the space occupied by the European standard plug on the shell 1, thereby reducing the overall length of the shell 1, reducing the overall volume of the product, and facilitating the development of miniaturization of the product.

[0026] Furthermore, the telescopic assembly includes a fixed rod 5, a first rocker arm 6 and a second rocker arm 7 which are hingedly connected in sequence, the end of the fixed rod 5 away from the first rocker arm 6 is fixed to the shell 1, the end of the second rocker arm 7 away from the first rocker arm 6 is hinged to the European standard bracket 8, the European standard sleeve 4 is provided with a driving groove 41, the end of the first rocker arm 6 away from the fixed rod 5 is provided with a driving protrusion 61, and the driving protrusion 61 can be slidably installed in the driving groove 41; when the European standard sleeve 4 slides out of the shell 1, the driving protrusion 61 slides from the first end 411 of the driving groove 41 to the second end 412 of the driving groove 41, the angle between the first rocker arm 6 and the second rocker arm 7 increases, and the second rocker arm 7 pushes the European standard bracket 8 to slide in the European standard sleeve 4.

[0027] As can be seen from the above description, by pushing the push handle 3 to move so that the European-standard sleeve 4 passes through the shell 1, the driving groove 41 on the European-standard sleeve 4 cooperates with the driving protrusion 61 on the first rocker 6, so that the angle between the first rocker 6 and the second rocker 7 is increased, so that the European-standard bracket 8 can produce two-stage displacement while the European-standard sleeve 4 moves, that is, the push handle 3 moves a stroke, and the European-standard bracket 8 can obtain two strokes; it can be seen that the European-standard sleeve 4 and the second live wire pin 83 and the second neutral wire pin 84 are also pushed out, and the stroke of the push handle 3 can be set shorter, reducing the proportion of the height space in the shell 1 when the push handle 3 is active; due to the long telescopic stroke of the traditional European-standard pin, the European-standard pin needs to be set away from the area where the British-standard pin 2 is located, and the above-mentioned telescopic component can effectively reduce the active stroke of the push handle 3 of the European-standard pin, so that the European-standard pin does not need to avoid the British-standard pin 2, and the European-standard pin is set in the area formed by the British-standard pin 2, which greatly improves the space utilization rate.

[0028] Furthermore, the telescopic assembly includes a first rack 1111, a second rack 85 and a gear 43, the gear 43 can be rotatably installed in the European standard sleeve 4, the first rack 1111 is installed in the shell 1 and extends along the sliding direction of the European standard sleeve 4, the second rack 85 is installed on the European standard bracket 8 and extends along the sliding direction of the European standard sleeve 4, the first rack 1111 and the second rack 85 are engaged on opposite sides of the gear 43.

The first rack 1111 is installed in the shell 1 and extends along the sliding direction of the European standard sleeve 4. The second rack 85 is installed on the European standard bracket 8 and extends along the sliding direction of the European standard sleeve 4. The first rack 1111 and the second rack 85 are meshed with opposite sides of the gear 43; specifically, one end of the first rack 1111 is installed on the upper bracket 111, and the other end of the first rack 1111 extends into the interior of the European standard sleeve 4 and meshes with the gear 43.

[0051] It can be understood that the first stroke is achieved by pushing the push handle 3 to move so that the European standard sleeve 4 passes through the shell 1. During this process, the first rack 1111 drives the gear 43 to rotate, and the meshing of the gear 43 and the second rack 85 drives the European standard bracket 8 to slide in the European standard sleeve 4 to achieve the second stroke, so that the second live wire pin 83 and the second neutral wire pin 84 on the European standard bracket 8 pass through the European standard sleeve 4; it can be seen that the stroke of the push handle 3 can be set shorter by pushing out the European standard sleeve 4, thereby reducing the proportion of the height space in the shell 1 when the push handle 3 is active; due to the long telescopic stroke of the traditional European standard pin, the European standard pin needs to be set away from the area where the British standard pin 2 is located, and the above-mentioned telescopic component can effectively reduce the active stroke of the push handle 3 of the European standard pin, so that the European standard pin does not need to avoid the British standard pin 2, and the European standard pin is set in the area formed by the British standard pin 2, which greatly improves the space utilization rate.

[0052] In summary, the travel converter provided by the present invention has the characteristics of compact structure. By arranging the first live wire pin and the first neutral wire pin of the British standard plug on the first side of the European standard sleeve, and arranging the grounding pin on the second side of the European standard sleeve, the space occupied by the British standard pin on the shell overlaps with the space occupied by the European standard pin on the shell, thereby reducing the overall length of the shell, reducing the overall volume of the product, and facilitating the development of miniaturization of the product.

[0053] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
