DETAILED DESCRIPTION

[0030] In order to make the technical solution and advantages of the utility model clearer, the utility model and its beneficial effects will be further described in detail below in combination with specific implementation methods and drawings of the specification, but the implementation methods of the utility model are not limited thereto.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0033] like Figures 1 to 5 As shown, a power adapter with a clamping function includes: an adapter body 1 and a clamping member 2, the clamping member 2 has two, both of which can be slidably arranged on the adapter body 1, and can slide along the length direction of the adapter body 1, and the adapter body 1 is provided with a protective cover 5; a screw 3, which can be rotatably installed on the adapter body 1, and the screw 3 has a first threaded portion 31 and a second threaded portion 32 with opposite threads, the first threaded portion 31 and the second threaded portion 32 are respectively threadedly connected with the clamping members 2 on both sides, and are used to drive the clamping members 2 on both sides to move closer to and away from each other; an adjusting shaft 4 is arranged at the right end of the screw 3, and is used to rotate the screw 3 through the adjusting shaft 4.

[0034] Specifically, the two clamping members 2 are respectively slidably arranged on the left and right sides of the top of the adapter body 1, and the two clamping members 2 are symmetrically distributed. When using the power adapter, the adjusting shaft 4 is rotated to drive the screw 3 to rotate, and the screw 3 rotates through the first threaded portion 31 and the second threaded portion 32 to drive the clamping members 2 on both sides to move simultaneously, and the clamping members 2 on both sides move closer to each other, so as to achieve the clamping and fixing function of the adapter body 1, and can fix the adapter body 1 on the specified object. For example, if it is not convenient to place the adapter body 1 on the desktop, the clamping members 2 on both sides of the table board are respectively moved to the upper and lower sides of the table board, and the clamping members 2 on both sides can be driven by the screw 3 to move closer to each other to clamp the table board, thereby achieving the purpose of fixing the adapter body 1 on the table board, and it can also be clamped and fixed on objects of different thicknesses. On the contrary, if the screw 3 is controlled to reverse, the clamping members 2 on both sides are driven to move away from each other, loosening the clamping of the table board, and then the adapter body 1 can be taken. At the same time, by driving the clamping part 2 to move and tighten the fixation through the screw rod 3, the clamping force of the clamping part 2 can be adjusted at any time to ensure that the adapter body 1 can be stably fixed on the pre-installed object; avoid using the elastic force of the spring as the clamping force of the clamping part 2. If the thickness of the pre-installed object is too low, the clamping part 2 for the pre-installed object will be smaller, and the clamping force of the clamping part 2 is too small, resulting in unstable installation of the adapter body. In addition, the spring is prone to attenuation of elastic force as the use time increases, which also affects the stability of the installation of the adapter body.

[0035] The adapter also includes a limit assembly 8, which is disposed between the adapter body 1 and the protective cover 5 and is used to cooperate with the screw rod 3 to limit the rotation of the screw rod 3. Specifically, when it is necessary to control the screw rod 3 to rotate and adjust the position of the clamping plate 22, the limit assembly 8 is first controlled to operate to release the limit on the rotation of the screw rod 3; after the clamping plates 22 on both sides clamp and fix the pre-installed object, the limit assembly 8 can be controlled to operate to limit the selection of the screw rod 3 to prevent the screw rod 3 from rotating easily after the adapter is clamped and fixed, causing the adapter to loosen and fall off.

[0036] In some embodiments of the present application, the protective cover 5 is disposed on the adapter body 1, and a receiving cavity is formed between the protective cover 5 and the adapter body 1, the screw 3 and the adjustment shaft 4 are both located in the receiving cavity, and the protective cover 5 is sequentially provided with a strip hole 51 and a through hole 52 along the length direction, the clamping members 2 all pass through the strip hole 51, and the adjustment shaft 4 at least partially passes through the through hole 52 to protrude outward. Specifically, the protective cover 5 is detachably disposed on the top of the adapter body 1 to form a receiving cavity, covering the screw 3, the adjustment shaft 4 and part of the clamping member 2, thereby improving the aesthetics and safety of use of the adapter. The provision of the strip hole 51 can achieve the goal of covering part of the clamping member 2 while avoiding affecting the movement of the clamping member 2. The upper part of the adjustment shaft 4 protrudes outward through the through hole 52. When the screw 3 needs to be rotated, the user only needs to manually slide the adjustment shaft 4 to rotate, thereby preventing the adjustment shaft 4 from being fully exposed to the outside, which is easy to be accidentally touched, causing the adapter body 1 to loosen after being fixed.

[0037] In some embodiments of the present application, the clamping member 2 includes a clamping plate 22 and a movable seat 21. The movable seat 21 is slidably connected to the adapter body 1 and at least partially passes through the bar hole 51. The clamping plate 22 can be rotatably installed on the top of the movable seat 21. The clamping plate 22 can be rotated to fit and close with the adapter body 1, and can be rotated to a vertical state to open.

[0038] Specifically, the moving seat 21 is slidably connected to the top of the adapter body 1, and the clamping plate 22 can be rotatably installed on the top of the moving seat 21. The clamping plate 22 is located outside the accommodating cavity. The front and rear ends of the moving seat 21 are provided with a stopper 211. The stopper 211 cooperates with the inner end surface of the clamping plate 22, so that when the clamping plate 22 rotates outward to a vertical state, the stopper 211 blocks the clamping plate 22, and the clamping plate 22 cannot continue to rotate outward. When the adapter body 1 needs to be fixed to a specified object, first rotate the clamping plates 22 on both sides outward to a vertical state and open. The clamping plates 22 on both sides in a vertical state form opposing clamps to achieve the clamping and fixing function of the adapter body 1. If the adapter body 1 does not need to be fixed, the clamping plates 22 on both sides can be rotated inward to fit and close with the top of the adapter body 1 to reduce the space occupied by the adapter.

[0039] In some embodiments of the present application, a mounting groove 221 is provided on one side of the two clamping plates 22 that are close to each other, a fastening plate 23 is provided in the mounting groove 221, the fastening plate 23 can slide along the depth direction of the mounting groove 221, and an elastic member 25 is provided between the fastening plate 23 and the bottom of the mounting groove 221. Specifically, the mounting groove 221 is a square groove, the fastening plate 23 can be slidably provided in the mounting groove 221, and when the elastic member 25 is in the initial state, the outer side of the fastening plate 23 protrudes from the surface of the clamping plate 22, and the elastic member 25 is a compression spring. When the user controls the screw 3 to rotate and drive the clamping plates 22 on both sides to move closer to each other, the fastening plate 23 first contacts the pre-installed object, and the clamping plate 22 continues to move. The fastening plate 23 is squeezed and retracted into the installation groove 221, and the elastic member 25 is compressed until the surface of the clamping plate 22 contacts and clamps the pre-installed object, and the screw 3 is stopped. While the clamping plates 22 on both sides are clamped and fixed with the pre-installed object, the fastening plate 23 squeezes the pre-installed object through the elastic force of the elastic member 25, further improving the clamping force of the clamping member 2, and ensuring the good stability of the adapter fixed on the object. In other embodiments, the installation groove 221 can be set as a circular groove, and can also be set as a groove of other shapes according to needs.

[0040] In some embodiments of the present application, a plurality of protrusions 24 are provided on the outer side of the fastening plate 23. Specifically, by providing a plurality of protrusions 24 on the outer end surface of the fastening plate 23, and the plurality of protrusions 24 are arranged in an array and evenly spaced, the friction force on the outer end surface of the fastening plate 23 is increased to prevent the fastening plate 23 from slipping after clamping and fixing the pre-installed object.

[0041] In some embodiments of the present application, the clamping plate 22 is provided with a first magnetic block 6, and the first magnetic block 6 and the mounting groove 221 are located on the same side. The second magnetic block 7 is provided on both sides of the top of the protective cover. When the clamping plate 22 is rotated to the closed state, the first magnetic block 6 can be magnetically attracted to the second magnetic block 7. Specifically, the first magnetic block 6 and the second magnetic block 7 are respectively located on the left and right sides of the top of the protective cover 5, and are respectively close to the two ends of the bar hole 51. If it is not necessary to fix the adapter body 1, first control the screw 3 to rotate to move the clamping members 2 on both sides to the two ends of the bar hole 51, and then rotate the clamping plates 22 on both sides inward to fit and close the top of the adapter body 1, and the first magnetic block 6 of the clamping plate 22 is in contact with the second magnetic block 7 on the protective cover 5. Through the magnetic attraction between the first magnetic block 6 and the second magnetic block 7, the clamping plate 22 and the protective cover 5 are fixed to prevent the clamping plate 22 from being easily rotated and opened after closing, which affects the user experience of the adapter.

[0042] In some embodiments of the present application, the limit assembly 8 includes a gear 81, an adjustment rod 82 and a tension spring 84. The gear 81 is arranged at the end of the screw rod 3, the gear 81 is far away from the adjustment shaft 4, the adjustment rod 82 is arranged on the protective cover 5, and can slide in the vertical direction, the end of the adjustment rod 82 has a limit rack 83, the limit rack 83 cooperates with the gear 81, the tension spring 84 is sleeved on the adjustment rod 82, and the two ends of the tension spring 84 are respectively connected to the adjustment rod 82 and the protective cover 5. Specifically, the adjustment rod 82 is arranged vertically and can slide in the vertical direction on the protective cover 5, the gear 81 is arranged at the left end of the screw rod 3, the limit rack 83 is located at the lower end of the adjustment rod 82, and cooperates with the gear 81. When the tension spring 84 is in the initial state, the limit rack 83 is meshed with the gear 81, and the adjusting rod 82 protrudes from the upper surface of the protective cover 5; when it is necessary to rotate the screw 3 to drive the clamping parts 2 on both sides to move, first press the adjusting rod 82 to move downward, the tension spring 84 is deformed, the limit rack 83 is disengaged from the gear 81, and the screw 3 is no longer limited in selection; when the clamping plates 22 on both sides clamp and fix the pre-installed object, the adjusting rod 82 is released, and then the tension spring 84 rebounds and resets, driving the limit rack 83 to reset and re-engage with the gear 81, thereby limiting the rotation of the screw 3, thereby preventing the risk of loosening and falling off after the adapter is clamped and fixed.

[0043] In some embodiments of the present application, the adjusting shaft 4 is provided with a plurality of convex strips 41, which are distributed around the adjusting shaft 4 in a radial direction and are evenly spaced. Specifically, a plurality of convex strips 41 are evenly spaced along the radial surface of the adjusting shaft 4 to increase the friction resistance of the radial surface of the adjusting shaft 4, so that the user can more conveniently control the rotation of the screw 3 by sliding the adjusting shaft 4.

[0044] In some embodiments of the present application, the adapter body 1 further includes a guide shaft 11, which is arranged along the length direction of the adapter body 1. The guide shaft 11 is slidably connected to the clamping member 2 and is used to install the clamping member 2 and guide the movement of the clamping member 2.
