Abstract
Description
Technical Field
[0001] The utility model relates to a conversion socket, in particular to a conversion socket in which the remaining pins can be locked when one pin is extended. Background Art
[0002] A conversion socket is a conversion device that allows pins of a certain specification to be converted into pins of another specification, making it easier for residents of different countries to use them internationally. Currently, there are six types of pin standards: Chinese standard, American standard, European standard, British standard, Australian standard, and South African standard. Conversion sockets generally include at least three of the above standards. Existing conversion sockets usually achieve conversion by sliding and retracting the pins when in use, that is, by pushing the pins that need to be used out of the shell, and pushing the unused pins into the shell and hiding them. However, when multiple pins are combined in a conversion socket, some pins are prone to accidentally slip out of the shell when not in use. For example, taking a conversion socket with four pins as an example, when one of the pins is used, due to the large number of pins, the other three pins are prone to accidentally extend, causing inconvenience to use and reducing safety. Utility Model Content
[0003] The utility model aims to provide a conversion socket in which the remaining pins can be locked when one pin is extended, thereby improving the safety of use.

The lock block is configured to lock the first prong, the second prong, the third prong, and the fourth prongs, respectively. The lock block is configured to lock the first prong, the second prong, the third prong, and the fourth prongs, respectively. The lock block is configured to lock the first prong, the second prong, the third prong, and the fourth prongs, respectively. The lock block is configured to lock the first prong, the second prong, the third prong, and the fourth prongs, respectively.
[0006] Preferably, a first guide post is provided on the inner bottom of the housing, and a first guide slot is provided on the main body, wherein the first guide post is slidably disposed in the first guide slot. The first guide post cooperates with the first guide slot to more accurately position the locking block and prevent the locking block from excessively shifting.
[0007] Specifically, a second guide post is provided on the inner bottom of the housing, and a second guide slot is defined in the main body. The second guide post is slidably disposed in the second guide slot; the second guide slot extends in the same direction as the first guide slot. The second guide post cooperates with the second guide slot, and in combination with the first guide post and the first guide slot, the two together restrict the locking block, thereby ensuring more accurate positioning of the locking block.
[0008] Preferably, a limit block is provided on the inner bottom of the housing, and a latch is provided on the main body, and when the locking block slides back and forth, the latch moves away from or latches on the limit block.

[0024] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.
[0025] like Figures 1 to 6 As shown, the conversion socket with a locking block 100 of the present invention includes a housing 1, a first pin 2, a second pin 3, a third pin 4, a fourth pin 5 and a locking block 6. The housing 1 is provided with a first socket 11, a second socket 12, a third socket 13 and a fourth socket 14 corresponding to the first pin 2, the second pin 3, the third pin 4 and the fourth pin 5; the first pin 2, the second pin 3, the third pin 4 and the fourth pin 5 are telescopically arranged in the housing 1, and the locking block 6 is slidably arranged in the housing 1; the locking block 6 includes a main body 61 and a first stopper 6a, a second stopper 6a and a second stopper 6b arranged on the main body 61. 6b, a third stopper 6c and a fourth stopper 6d; the first stopper 6a is provided with a first guiding inclined surface 6a1 which slides with the first pin 2; the second stopper 6b is provided with a second guiding inclined surface 6b1 which slides with the second pin 3; the third stopper 6c is provided with a third guiding inclined surface 6c1 which slides with the third pin 4; the fourth stopper 6d is provided with a fourth guiding inclined surface 6d1 which slides with the fourth pin 5; when any one of the first stopper 6a, the second stopper 6b, the third stopper 6c and the fourth stopper 6d releases the pin corresponding to itself, the other three stoppers block the pin corresponding to themselves from extending out of the corresponding socket.
[0026] See also Figure 2 、 Figure 3 and Figure 6The inner bottom of the shell 1 is provided with a first guide column 1a, the main body 61 is provided with a first guide groove 611, and the first guide column 1a is slidably arranged in the first guide groove 611. By matching the first guide column 1a with the first guide groove 611, the position of the lock block 6 can be more accurate, and the lock block 6 can be prevented from being excessively displaced. Specifically, the inner bottom of the shell 1 is provided with a second guide column 1b, the main body 61 is provided with a second guide groove 612, and the second guide column 1b is slidably arranged in the second guide groove 612; the extension direction of the second guide groove 612 is the same as the extension direction of the first guide groove 611. By matching the second guide column 1b with the second guide groove 612, and combining the matching of the first guide column 1a with the first guide groove 611, the lock block 6 is limited by the two, so that the position of the lock block 6 can be more accurately positioned.
[0027] Please refer to Figure 2 , Figure 3 and Figure 6 , the inner bottom of the shell 1 is provided with a limiting block 1c, the main body 61 is provided with a clamping position 613, when the lock block 6 slides back and forth, the clamping position 613 is away from or clamped in the limiting block 1c. By matching the limiting block 1c with the clamping position 613, the main body 61 can be prevented from moving excessively.
[0028] As shown in Figure 3 , the first side 6f of the lock block 6 extends out of the first blocking part 6a; the second side 6g of the lock block 6 extends out of the first branch arm 62, the second blocking part 6b and the third blocking part 6c are arranged on the first branch arm 62; the third side 6h of the lock block 6 opposite to the first branch arm 62 extends out of the second branch arm 63, and the fourth blocking part 6d is arranged on the second branch arm 63; the first side 6f is adjacent to the second side 6g and the third side 6h respectively. The first branch arm 62 is in a bent structure and forms a forearm 621 and a rear arm 622, the second blocking part 6b is arranged on the forearm 621, and the third blocking part 6c is arranged at the end of the rear arm 622. The main body 61 has a fourth side 6k opposite to the first side 6f, the second branch arm 63 extends outwardly from between the fourth side 6k and the third side 6h, and the fourth blocking part 6d is arranged at the end of the second branch arm 63.
[0029] As shown in Figure 3 and Figure 6As shown, a fifth stopper 6e extends from the second side 6g of the locking block 6. The fifth stopper 6e is provided with a fifth guide slope 6e1. The fifth stopper 6e is spaced a certain distance from the second stopper 6b, and the second stopper 6b and the fifth stopper 6e are located on opposite sides of the second insertion hole 12. Because the second pin 3 is located between the first pin 2 and the third pin 4, the locking block 6 will move back and forth when the first pin 2 and the third pin 4 are in use. However, the second stopper 6b cannot prevent the second pin 3 from extending from the second insertion hole 12 in both situations. Therefore, by providing the fifth stopper 6e and cooperating with the second stopper 6b, the second pin 3 can be blocked when both the first pin 2 and the third pin 4 are in use, making it safer to use.
[0030] Combine Figure 1 , see Figure 5 The ends of the second, third, and fourth pins 3, 4, and 5 are each provided with a push-up bevel 31 or arcuate surface to engage with the guide bevels of their respective stoppers. The provision of the push-up bevel 31 makes it easier for the pins to push their respective stoppers to rotate, thereby making operation smoother.
[0031] See also Figure 3 、 Figure 4 and Figure 6 The first pin 2 has an inwardly concave recess 21 on the side facing the locking block 6. This recess 21 allows the first stopper 6a to enter or exit, allowing it to block or release the first pin 2. A push ramp 22 is provided on the top wall of the recess 21. This push ramp 22 pushes the first stopper 6a as the first pin 2 slides out of the housing 1. The recess 21 allows it to cooperate with the first pin 2 to achieve the purpose of blocking or releasing. The push ramp 22, in turn, allows the first stopper 6a to move when the first pin 2 slides out, thereby moving the locking block 6 and automatically blocking the other pins.
[0032] Combining the above and Figures 6 to 9 The following describes in detail the usage of the lock block conversion socket 100 of the present invention:
[0033] like Figure 6As shown, when the first pin 2 is needed, it is pushed out of the first socket 11. At this time, the pushing inclined surface 22 on the first pin 2 and the first guiding inclined surface 6a1 on the first stop 6a interfere with each other, thereby pushing the locking block 6 to move, so that the first stop 6a leaves the recess 21, and the first pin 2 can be extended out of the first socket 11. At the same time, the second stop 6b, third stop 6c, and fourth stop 6d on the locking block 6 are respectively located in the second socket 12, third socket 13, and fourth socket 14, thereby preventing the second pin 3, third pin 4, and fourth pin 5 from extending.
[0034] like Figure 7 As shown, when the second pin 3 is needed, it is pushed out of the second socket 12. At this time, the pushing inclined surface 31 on the second pin 3 and the second guiding inclined surface 6b1 on the second stop 6b interfere with each other, thereby pushing the locking block 6 to move, causing the second stop 6b to leave the second socket 12, and the second pin 3 can be extended out of the second socket 12. At the same time, the first stop 6a on the locking block 6 is inserted into the recessed portion 21, and the third stop 6c and fourth stop 6d are located on the third socket 13 and the fourth socket 14, respectively, thereby preventing the third pin 4 and the fourth pin 5 from extending.
[0035] like Figure 8 As shown, when the third pin 4 is needed, it is pushed out of the third socket 13. At this time, the pushing inclined surface on the third pin 4 and the third guiding inclined surface 6c1 on the third stopper 6c interfere with each other, thereby pushing the locking block 6 to move, causing the third stopper 6c to leave the third socket 13, and the third pin 4 can be extended out of the third socket 13. At the same time, the first stopper 6a on the locking block 6 is inserted into the recessed portion 21, and the fifth stopper 6e and the fourth stopper 6d are located on the second socket 12 and the fourth socket 14, respectively, thereby preventing the second pin 3 and the fourth pin 5 from extending.
[0036] like Figure 9 As shown, when the fourth pin 5 is needed, it is pushed out of the fourth insertion hole 14. At this time, the pushing inclined surface on the fourth pin 5 and the fourth guiding inclined surface 6d1 on the fourth stopper 6d interfere with each other, thereby pushing the locking block 6 to move, causing the fourth stopper 6d to leave the fourth insertion hole 14, and the fourth pin 5 can be extended out of the fourth insertion hole 14. At the same time, the first stopper 6a on the locking block 6 is inserted into the recessed portion 21, and the third stopper 6c and the fifth stopper 6e are located on the third insertion hole 13 and the second insertion hole 12, respectively, thereby preventing the third pin 4 and the second pin 3 from extending.
[0037] Compared with the prior art, since the utility model discloses a lock block 6 is arranged in the shell 1 and is slidably arranged, first, second, third and fourth blocking portions 6a, 6b, 6c and 6d are arranged on the lock block 6, the first, second, third and fourth blocking portions 6a, 6b, 6c and 6d can block the first, second, third and fourth pins 2, 3, 4 and 5 respectively, and first, second, third and fourth guide inclined surfaces 6a1, 6b1, 6c1 and 6d1 are arranged on the first, second, third and fourth blocking portions 6a, 6b, 6c and 6d respectively, therefore, when one pin extends out of the corresponding jack, the corresponding guide inclined surface can push the lock block 6, so that the corresponding blocking portion releases the pin, and the other three pins are just blocked by the lock block 6, preventing the pins from extending out of the jacks accidentally, therefore, the pin can automatically control the movement of the lock block 6 when in use, without the need for the user to operate, and the utility model is very convenient to use and greatly improves the safety in use.
[0038] The structure of the first, second, third and fourth pins 2, 3, 4 and 5 related to the utility model with the lock block conversion socket 100 is well known to those skilled in the art, and detailed description is not given here.
[0039] The above only discloses preferred examples of the utility model, and of course cannot limit the scope of the utility model, therefore, equivalent changes made according to the patent application scope of the utility model still belong to the scope covered by the utility model.
