Description

Technical Field

[0001] The utility model relates to the technical field of conversion plugs, in particular to a travel conversion plug fixing assembly. Background Art

[0002] When traveling across multiple countries, for example, you might need to carry an adapter to reduce the number of chargers you need to carry. This adapter allows you to use the same charger in multiple countries with different charger specifications. When the adapter prongs are retracted or extended, they must be positioned between the active and inactive positions to facilitate storage and normal use. Utility Model Content

[0003] The purpose of the present utility model is to provide a travel adapter fixing assembly to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is as follows: a travel conversion plug fixing assembly, comprising: a shell, which is provided with a slide groove; a pin assembly, comprising a base and a conductive pin mounted on the base, the base being slidably mounted on the shell, and a connecting rod slidably mounted on one side of the base being mounted, the connecting rod extending from the shell at one end away from the base and being mounted with a button; a card block being slidably mounted on the shell along a direction perpendicular to the length of the slide groove, when the pin assembly is in a first state, the upper end of the base is in conflict with the lower end of the card block, and when the pin assembly is in a second state, the lower end of the base is in conflict with the upper end of the card block; a first elastic member is mounted between the card block and the shell, and a second elastic member is mounted between the base and the connecting rod, when the button is pressed, the connecting rod can overcome the elastic force of the second elastic member and move toward the card block, and push the card block to overcome the elastic force of the second elastic member and move, so that the upper end or lower end of the card block is out of the state of conflicting with the lower end or upper end of the base.

[0005] This technical solution has at least the following beneficial effects: when the button is pressed, the connecting rod pushes the clamping block to move, causing the clamping block to break away from the interfering connection with the pin assembly, thereby allowing the button to be further pushed, extending the pin assembly and the conductive pin out of the housing or into the housing. After the button is released, the elastic force of the first elastic member causes the clamping block to be in an interfering state with the pin assembly, thereby stabilizing the first or second state of the pin assembly. At the same time, the elastic force of the second elastic member restores the button to its pre-pressed state, enabling repeated operation. This allows the conductive pin to be stored and used normally.

[0006] As a further improvement to the above technical solution, the upper or lower end of the clamping block abuts against the lower or upper end of the middle portion of the base. This abutment restriction of the middle portion of the base improves the stability of the pin assembly when restrained, thereby increasing the reliability of the conductive pins during storage and normal use.

[0007] As a further improvement to the above technical solution, the contact surfaces between the clamping block and the base are tilted in the direction of mutual interlocking. When the base is restrained by the clamping block, the clamping block and the base interlock with each other in an inwardly interlocking manner, making it less likely that the clamping block will fail to restrain the pin assembly due to oscillation such as falling, thereby improving the reliability of the conductive pin storage and normal use.

[0008] As a further improvement of the above technical solution, the second elastic member is an elastic plate, one end of which is mounted on the base and the other end is mounted on the connecting rod. The elastic plate can improve the integrity between the base and the connecting rod, facilitating production and manufacturing.

[0009] As a further improvement to the above technical solution, the connecting rod is provided with a pressure block, and the upper and lower ends of the inner side of the housing are respectively provided with pressure grooves for the pressure block to be inserted into. When the pin assembly is in the first state and the second state, the second elastic member can provide the connecting rod with elastic force to cause the pressure block to be inserted into the pressure groove. In the first and second states, the pin assembly is not only restrained by the block on the base, but also by the sidewalls of the pressure groove, which further restrains the base, thereby further improving the stability and reliability of the pin assembly in the first and second states.

[0010] As a further improvement to the above technical solution, when the pin assembly is in the second state, the conductive pins do not extend out of the housing, and the lower end of the base does not interfere with the upper end of the clamping block. In this second state, the conductive pins do not extend out of the housing. They do not need to be subjected to the same force as when extended for insertion into a socket. Therefore, the clamping block can be removed from restricting the base, thereby reducing the stability requirements of the base and thus lowering production costs.

[0011] As a further improvement to the above technical solution, at least two pin assemblies are provided, and two adjacent bases are restrained by a block located between them. One block can restrain two bases on either side, reducing the number of blocks, taking up less space, and lowering production costs.

[0012] As a further improvement to the above technical solution, a clearance notch is provided in the middle of the card block, and the position where the card block contacts the base is located on the side wall of the clearance notch. The provision of the clearance notch can reduce the space occupied by the card block within the housing, reducing the overall space size, making the housing more compact and easier to carry.

[0013] As a further improvement to the above technical solution, the end of the elastic plate away from the base is tilted toward the slide groove. The compressed side of the elastic plate is tilted in the direction of the force, which can reserve a larger elastic deformation space, thereby enabling the elastic plate to provide better elastic performance. Moreover, after being compressed, the tilt angle of the tilted elastic plate decreases. When the button is pushed, the elastic plate can better transmit the force along the slide groove, thereby facilitating the movement of the base, improving the sliding stability of the button and base, and making the extension process of the conductive foot more stable and smooth.

[0014] As a further improvement to the above technical solution, a first baffle is installed in the housing, the first baffle being positioned to block the opening of the slide slot, and the base having a guide slot for the first baffle to slide through. The first baffle serves to prevent dust and also guides the base, improving the stability of its movement. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] Example 1:

[0040] Reference Figure 1-7The travel adapter fixing assembly includes a housing 100, a pin assembly 200, and a block 400. A slide slot 110 is defined on the right side of the housing 100. The pin assembly 200 is longitudinally slidably disposed within the housing 100. The pin assembly 200 includes a base 210 and a conductive pin 220. The conductive pin 220 is fixedly mounted at the bottom of the base 210 and longitudinally slidably disposed within the housing 100. A socket is defined at the bottom of the housing 100, the position of the socket aligning with the position of the conductive pin 220. When the pin assembly 200 is pushed, the conductive pin 220 extends from the socket and out of the housing 100.

[0041] A connecting rod is installed on the right side of the base 210. The connecting rod 230 is slidably set on the slide groove 110. The end of the connecting rod 230 away from the base 210 is integrally connected with a button 240. The button 240 is located outside the shell 100 for people to operate the button 240.

[0042] A second elastic member 300 is mounted between the base 210 and the connecting rod 230. The second elastic member 300 is an elastic plate. The top of the elastic plate is tilted toward the right, i.e., toward the side of the chute 110, and is integrally connected to the left side of the connecting rod 230. The bottom of the elastic plate is tilted toward the left and is integrally connected to the right side of the base 210. The base 210, elastic plate, connecting rod 230, and button 240 can be made of a plastic integral molding. The elastic deformation of the elastic plate allows the button 240 and connecting rod 230 to move leftward relative to the base 210 against their own elastic force. After releasing the button 240, the elastic force of the elastic plate allows the button 240 and connecting rod 230 to return to their original rightmost position. A guide slot 610 is defined between the base 210 and the elastic plate. A first baffle 600 is mounted within the housing 100 and is inserted into the guide slot 610, thereby guiding the longitudinal sliding of the base 210. Furthermore, the width of the first baffle 600 is greater than the width of the chute 110 , so that the first baffle 600 covers the opening of the chute 110 , thereby achieving a good dust-proof effect.

[0043] When the connecting rod 230 slides to the upper and lower ends of the slide slot 110, the pin assembly 200 moves to the second and first positions, respectively. When the pin assembly 200 is in the second position, the conductive pin 220 is inside the housing 100; when the pin assembly 200 is in the first position, the conductive pin 220 is extended outside the housing 100 for use.

[0044] In other embodiments, the second elastic member 300 may adopt a second coil spring, and the connecting rod 230 is slidably sleeved on the right side of the base 210. One end of the second coil spring is fixed to the left side of the connecting rod 230, and the other end is fixed to the right side of the base 210, so that the second coil spring provides elastic force to move the connecting rod 230 away from the base 210.

[0045] In this embodiment, the top and bottom of the block 400 are respectively embedded in the inner side of the housing 100, and the block 400 can slide left and right relative to the housing 100. A first elastic member 410 is installed between the block 400 and the housing 100. The first elastic member 410 is a first coil spring. One end of the first coil spring contacts the right side of the housing 100, and the other end contacts the left side of the block 400. Under the action of the first coil spring, the block 400 can be pushed to the rightmost position, at which point the right side of the block 400 just contacts the top of the elastic plate. A clearance notch 420 is provided in the middle of the block 400. The clearance notch 420 extends through the front, back, and top sides of the block 400, giving the block 400 an overall U-shaped structure. When the block 400 is at the rightmost position, the middle position of the base 210 conflicts with the position of the block 400 close to the left side wall of the notch 420 , so that the block 400 can firmly limit the middle position of the base 210 .

[0046] Specifically, when the pin assembly 200 is in the first state, the conductive pin 220 extends out of the housing 100, and the upper end of the base 210 contacts the lower end of the block 400, preventing the base 210 from moving upward and retracting the conductive pin 220. This satisfies the requirement for inserting the conductive pin 220 into the socket under force during use. By pressing the button 240, the connecting rod 230 overcomes the elastic force of the elastic plate and pushes the block 400. The block 400 overcomes the elastic force of the first coil spring and moves leftward, thereby releasing the block 400 from the contact state with the base 210. Then, by pushing the button 240 upward, the base 210 is no longer restricted by the block 400, which drives the pin assembly 200 as a whole upward, retracting the conductive pin 220 into the housing 100. When the conductive pin 220 is completely inserted into the housing 100, the pin assembly 200 is in the second state. When the button 240 is released, the first coil spring causes the clamping block 400 to move rightward to the rightmost position. At this time, the upper end of the clamping block 400 abuts against the lower end of the base 210, thereby limiting the movement of the pin assembly 200 and preventing the conductive pin 220 from automatically extending out of the housing 100, thereby ensuring stable storage of the conductive pin 220.

[0047] When the upper end of the clamping block 400 contacts the lower end of the base 210, the contact surface 500 of the clamping block 400 and the base 210 is an inclined surface with a lower left side and a higher right side. When the lower end of the clamping block 400 contacts the upper end of the base 210, the contact surface 500 of the clamping block 400 and the base 210 is an inclined surface with a higher left side and a lower right side. Therefore, when the clamping block 400 and the base 210 contact each other, the contact surfaces of the two are in a mutually locked state, thereby reducing the possibility of loosening and disengagement.

[0048] In this embodiment, there are three pin assemblies 200, and the conductive pins 220 in each of the three pin assemblies 200 have different specifications. Correspondingly, there are also three components, such as the slide slot 110, the connecting rod 230, and the button 240. The three pin assemblies 200 are arranged side by side in the front-to-back direction. Pressing a different button 240 moves the corresponding pin assembly 200. There are two locking blocks 400. The first locking block 400 is located in front of the first pin assembly 200 and is used to restrain the base 210 in the first pin assembly 200. The second locking block 400 is located between the second and third pin assemblies 200 and is used to restrain the bases 210 in the second and third pin assemblies 200. It is understood that pressing the second and third buttons will cause the second locking block 400 to move, thereby releasing the restraints on the second and third bases 210. The number of the card blocks 400 can be saved, thereby reducing the production cost.

[0049] In other embodiments, the number of pin assemblies 200, slide slots 110, connecting rods 230, and buttons 240 may be two, four, five, six, etc., and the corresponding number of clamping blocks 400 may be one, two, three, three, etc. It is understood that when the number of components such as the pin assembly 200 is an odd number greater than two, the number of clamping blocks 400 is half of the number of pin assemblies 200 minus one; when the number of components such as the pin assembly 200 is an even number, the number of clamping blocks 400 is half of the number of pin assemblies 200.

[0050] Example 2:

[0051] Reference Figure 8-12 This embodiment differs from the first embodiment in the structure of the locking block 400 and the additional provision of a pressing block 310 and a pressing groove 320. In this embodiment, the pressing block 310 is integrally formed between the connecting rod 230 and the elastic plate, and pressing grooves 320 are provided at the upper and lower ends of the right inner side of the housing 100. When the pin assembly 200 is in the first and second positions, and under the elastic action of the elastic plate, the pressing block 310 engages with the lower and upper pressing grooves 320, respectively, thereby further stabilizing the first and second positions of the pin assembly 200. Pressing the button 240 pushes the top of the elastic plate to the left, causing the pressing block 310 to escape from the pressing groove 320, releasing the restraint imposed by the pressing groove 320 on the pin assembly 200 and allowing the pin assembly 200 to move.

[0052] Furthermore, since the conductive pins 220 do not need to be excessively restricted when inside the housing 100, they can remain stable inside the housing 100. Therefore, when the pin assembly 200 is in the second state, i.e., the conductive pins 220 are inside the housing 100, there is no interference or restriction between the upper end of the clamping block 400 and the lower end of the base 210. This simplifies the structure of the clamping block 400, reduces its complexity and manufacturing cost.

[0053] In addition, in other embodiments, regardless of whether the pin assembly 200 is in the first state or the second state, the pressing block 310 and the locking block 400 can restrict the pin assembly 200, thereby increasing the stability of the pin assembly 200 in the first state and the second state, and ensuring the storage and normal use of the pin assembly 200.

[0054] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
