Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with a protection function. Background Art
[0002] A power adapter is a device widely used in various electronic devices that converts alternating current (AC) into direct current (DC) to power or charge portable electronic devices. A traditional power adapter consists of a housing that houses components such as a transformer and a rectifier circuit, and an external plug or prong for connecting to the power grid and an output port for connecting to a device.
[0003] For example, in the disclosed patent "Power Adapter" with announcement number CN216980974U, when the power adapter is not in use, the plug portion of the power adapter is exposed. On the one hand, the sharp plug portion may collide with other objects, causing damage to the plug portion or the object. On the other hand, the plug portion is exposed to the air for a long time, and its surface is easily contaminated or oxidized, causing the power adapter to malfunction.
[0004] In summary, with continuous progress, consumers' demand for power adapters is no longer limited to basic functional realization. For example, when the power adapter is not in use, the pins lack effective protection measures and are exposed. They are easily bumped and squeezed during daily storage, causing the pins to deform or damage. They are also easily affected by environmental factors such as moisture, causing the pins to oxidize and corrode, affecting the performance and life of the power adapter.
[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content
[0006] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.
[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a power adapter with a protective function, comprising a power adapter body, an output line connected to one side of the power adapter body, a boss formed on one side of the power adapter body, and two pins provided on the boss;
[0008] The boss is covered with a protective cover, which has through holes for two pins to pass through;
[0009] Two slideways are symmetrically arranged on the circumference of the boss, and sliders are symmetrically arranged on the inner side of the protective cover to be slidably connected with the slideways;
[0010] The slideway comprises a first transverse slideway close to the lower end of the boss, a second transverse slideway close to the upper end of the boss, and a longitudinal slideway connected between the first transverse slideway and the second transverse slideway.
[0011] As a further solution of the utility model: a soft rubber tape is provided in the through hole, and two slots are provided in the soft rubber tape for the pins to pass through;
[0012] Wherein, line openings are provided at both ends of the slot.
[0013] As a further solution of the present invention: a limiting notch is provided on the lower bottom surface of the second transverse slide away from one end of the longitudinal slide.
[0014] As a further solution of the present invention: elastic damping blocks are provided on both sides of the inner wall of the limiting notch.
[0015] As a further solution of the present invention: damping notches corresponding to the elastic damping blocks are formed on both sides of the slider.
[0016] As a further solution of the present invention: recessed notches are formed on both sides of the protective cover, and anti-slip strips are provided in the recessed notches.
[0017] As a further solution of the utility model: the elastic damping block is made of silicone material.
[0018] As a further solution of the utility model: the soft rubber cloth is made of rubber material.
[0019] As a further solution of the utility model: the protective cover is made of insulating plastic.
[0020] As a further solution of the present invention: force-bearing parts are formed on both side ends of the power adapter body.
[0021] Compared with the prior art, the advantageous effects of the present technical solution are as follows: when in use, the protective cover is sleeved on the boss, and the two pins are exposed, so that the pins can be inserted into the socket; and when not in use, the protective cover is rotated to move the slider from the first transverse slideway into the longitudinal slideway, and then the protective cover is lifted up, so that the protective cover covers the pins while the slider slides from the longitudinal slideway into the second transverse slideway, and then the protective cover is rotated to move the slider into the second transverse slideway, and the second transverse slideway is used to limit the slider, preventing the slider and the protective cover from moving downward, thereby using the protective cover to protect the unused pins, preventing the pins from being subjected to collision, extrusion, etc., resulting in deformation or damage that affects use;
[0022] After the protective cover covers the two pins, soft tape is placed in the through-hole and two slots are opened in the soft tape for the two pins to pass through. In this way, the soft tape increases the coverage area of the two pins, reduces the contact between the pins and the air, and reduces the impact of environmental factors such as moisture on the pins, effectively improving the performance and life of the power adapter.
[0023] At the same time, by opening a line of a certain length at both ends of the slot, when the protective cover rotates and the soft tape and the two pins rotate relative to each other, the line opening is used to prevent the two pins from colliding with the soft tape during rotation;
[0024] By allowing the slider to enter the limiting notch and then utilizing the damping notch of the slider to counteract the elastic damping block in the limiting notch, the tightness of the protective cover can prevent the protective cover from moving under the influence of gravity when the pin is placed downward, causing the slider to move from the limiting notch to the second horizontal slide, and then be affected by shaking to move to the longitudinal slide and then to the first horizontal slide, causing the protective cover to no longer cover the pin.

DETAILED DESCRIPTION
[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] See also Figure 1-6 A power adapter with a protective function includes a power adapter body 1, an output line 11 is connected to one side of the power adapter body 1, a boss 2 is formed on one side of the power adapter body 1, two pins 21 are provided on the boss 2, and the boss 2 is cylindrical.
[0037] The boss 2 is covered with a protective cover 3, which has an opening on one side so as to be sleeved on the boss 2. The protective cover 3 has through holes 31 for the two pins 21 to pass through.
[0038] Two slideways 22 are symmetrically provided on the circumference of the boss 2, and a slider 32 is symmetrically provided on the inner side of the protective cover 3 and is slidably connected to the slideways 22;
[0039] The slideway 22 includes a first transverse slideway 221 close to the lower end of the boss 2 , a second transverse slideway 222 close to the upper end of the boss 2 , and a longitudinal slideway 223 communicating between the first transverse slideway 221 and the second transverse slideway 222 .
[0040] Specifically, when in use, the protective cover 3 is sleeved on the boss 2, and the two pins 21 are exposed, so that the pins 21 can be inserted into the socket. When not in use, the protective cover 3 is rotated from one end of the first horizontal slide 221 to the direction of the longitudinal slide 223, so that the sliders 32 on both sides of the inner wall of the protective cover 3 enter the longitudinal slide 223 from the first horizontal slide 221, and then the protective cover 3 is lifted up, so that the protective cover 3 covers the pins 21 while the sliders 32 slide upward from the longitudinal slide 223 to the second horizontal slide 222, and then the protective cover 3 is lifted up. The slide 223 is rotated a second time in the direction of the second transverse slide 222, so that the slider 32 enters the second transverse slide 222, and the second transverse slide 222 is used to limit the slider 32 to prevent the slider 32 and the protective cover 3 from moving downward, so that the unused pins 21 are protected by the protective cover 3 to prevent the pins 21 from being collided, squeezed, etc., resulting in deformation or damage that affects use. When the protective cover 3 moves up to cover the two pins 21, the through holes 31 opened on the protective cover 3 are used to prevent the protective cover 3 from being pressed by the pins 21 when it rotates.
[0041] In the embodiment of the present invention, a soft adhesive tape 5 is provided in the through hole 31 , and two slots 51 are provided in the soft adhesive tape 5 for the pins 21 to pass through;
[0042] Two ends of the slot 51 are provided with linear openings 52 .
[0043] Specifically, the protective cover 3 covers the two pins 21 for protection. A soft tape 5 is placed in the through hole 31, and two slots 51 are formed in the soft tape 5 for the two pins 21 to pass through. Thus, the soft tape 5 increases the coverage area of the two pins 21, reduces the contact between the pins 21 and air, and reduces the impact of environmental factors such as moisture on the pins 21, thereby effectively improving the performance and life of the power adapter.
[0044] At the same time, by opening line openings 52 of a certain length at both ends of the slot 51, when the protective cover 3 rotates and the soft tape 5 and the two pins 21 rotate relative to each other, the line openings 52 can prevent the two pins 21 from colliding with the soft tape 5 during rotation.
[0045] Furthermore, a limiting notch 224 is formed on the lower surface of the second transverse slide 222 away from one end of the longitudinal slide 223 .
[0046] Specifically, after the protective cover 3 covers and protects the pin 21 and the slider 32 slides to the end of the second transverse slide 222 away from the longitudinal slide 223, the protective cover 3 is pushed down to move the slider 32 into the limiting notch 224. The limiting notch 224 is used to limit the slider 32 to prevent the slider 32 from moving from the second transverse slide 222 to the longitudinal slide 223 by itself, causing the protective cover 3 to move downward by itself and lose protection for the pin 21.
[0047] Furthermore, elastic damping blocks 4 are provided on both sides of the inner wall of the limiting notch 224 .
[0048] At the same time, when the slider 32 moves into the limiting notch 224, it squeezes the elastic damping block 4 on the inner wall of the limiting notch 224. The elastic restoring force of the elastic damping block 4 then secures the slider 32 in the limiting notch 224. This prevents the protective cover 3 from moving due to gravity when the pin 21 is placed downward, causing the slider 32 to move from the limiting notch 224 to the second transverse slide 222 and then to move to the longitudinal slide 223 and then to the first transverse slide 221 due to shaking, causing the protective cover 3 to no longer cover the pin 21.
[0049] The elastic damping block 4 is made of silicone material.
[0050] Furthermore, damping notches 33 corresponding to the elastic damping blocks 4 are formed on both sides of the slider 32 .
[0051] At the same time, when the slider 32 enters the limiting notch 224 , the elastic damping block 4 can be tightly pressed against the damping notch 33 , thereby further increasing the tightness of the slider 32 in the limiting notch 224 .
[0052] Furthermore, recessed notches 34 are formed on both sides of the protective cover 3 , and anti-slip strips 341 are provided in the recessed notches 34 .
[0053] Specifically, the recessed notches 34 formed on both sides facilitate the user to control the rotation and up and down pushing and pulling of the protective cover 3, providing a fulcrum for the user's hand. At the same time, the anti-slip strips 341 set in the recessed notches 34 can also prevent sliding, further improving the controllability.
[0054] Preferably, the soft tape 5 is made of rubber material; when the soft tape 5 is made of rubber material, when the soft tape 5 and the pin 21 rotate relative to each other, the open end of the line opening 52 can be deformed when it collides with the pin 21, thereby not hindering the normal rotation of the protective cover 3. At the same time, rubber has excellent insulation performance, which can ensure the insulation of the power adapter during use and avoid accidental touch.
[0055] More preferably, the protective cover 3 is made of insulating plastic, specifically PC or PBT, so that the protective cover 3 can ensure insulation while ensuring sufficient strength.
[0056] In the embodiment of the present invention, force-bearing portions 12 are formed on both side ends of the power adapter body 1 .
[0057] Specifically, the force-bearing portions 12 on both sides can facilitate inserting the plug pin 21 into the socket or pulling the plug pin out of the socket.
[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
