Description

Technical Field

[0001] This utility model relates to the field of charger technology, specifically to a charging anti-drop-off structure for an electric tool charger. Background Technology

[0002] The reference patent, entitled "A Charger for an Electric Tool" (Patent Publication No.: CN210074847U, Patent Publication Date: 2020.02.14), includes a charger body. A charging slot is provided on the upper surface of the charger body, and a conductive piece is provided inside the charging slot. A refrigerant chamber is fixed inside the charger body corresponding to the bottom surface of the charging slot. The refrigerant chamber contains refrigerant and has an L-shaped cross-section, including a horizontal receiving cavity and a vertically extending end. A gas collection hood is fixed to the port of the vertically extending end. During charging, the heat generated by the lithium battery can be quickly transferred to the refrigerant. After the refrigerant absorbs heat and evaporates, it is sealed and collected by the gas collection hood, thereby reducing the temperature at the contact point between the lithium battery and the charging slot. The evaporated gas collected by the gas collection hood is slowly cooled into liquid and flows back to the refrigerant chamber, thus continuously cooling the charger. Compared with the traditional air-cooled structure of chargers, it has a high-quality and efficient heat dissipation effect, thereby ensuring the safe operation of the charger.

[0003] Based on the above-mentioned document, existing power tool chargers generally charge lithium batteries by directly inserting the power tool's lithium battery into the charging slot, which lacks an anti-detachment structure. This results in poor stability of the lithium battery during the charging process, making it prone to detachment. Therefore, this utility model provides a charging anti-detachment structure for a power tool charger. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a charging anti-detachment structure for power tool chargers, solving the problem that existing power tool chargers lack an anti-detachment structure, resulting in poor stability of lithium batteries during charging and a tendency for them to detach.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a charging anti-drop structure for an electric tool charger, comprising a charger body and a plug, wherein the charger body has a wire winding mechanism inside, and an anti-drop mechanism inside, the anti-drop mechanism comprising:

[0006] The anti-detachment component includes a sliding rod slidably installed inside the charger body. One end of the sliding rod is rotatably connected to a rotating rod, and the other end of the sliding rod is fixedly connected to a moving block. A limit spring is fixedly connected to one side of the moving block. One end of the limit spring is fixedly connected to the inner wall of the charger body. A clamping block is fixedly connected to the other side of the moving block. The surface of the clamping block is slidably connected to the interior of the charger body.

[0007] The control components are located inside the charger body.

[0009] Preferably, the take-up mechanism includes:

[0010] The cable take-up assembly includes a take-up rod rotatably mounted inside the charger body, a take-up reel fixedly connected to the surface of the take-up rod, a ratchet fixedly connected to the surface of the take-up rod, and a rotating block fixedly connected to one end of the take-up rod;

[0011] The positioning component is located inside the charger body.

[0012] Preferably, the positioning assembly includes a connecting rod installed on the inner wall of the charger body, one end of the connecting rod is rotatably connected to a positioning rod, one end of the positioning rod extends through to the outside of the charger body, the surface of the positioning rod is slidably connected to the inside of the charger body, the other end of the positioning rod is in contact with the surface of the ratchet, and a positioning spring is fixedly connected to the top of the positioning rod, one end of the positioning spring is fixedly connected to the top of the inner cavity of the charger body.

[0015] Beneficial effects

[0016] This utility model provides a charging anti-drop-off structure for an electric tool charger. Compared with the prior art, it has the following advantages:

[0017] (1) The charging anti-drop structure of the power tool charger is achieved by pressing the control lever to drive the control block to slide downward. The sliding of the control block causes one end of the rotating rod to rotate inside the control block, and the other end of the rotating rod to rotate at the other end of the sliding rod. This causes the sliding rod to slide inside the charger body. The sliding of the sliding rod causes the moving blocks and clamping blocks on both sides to slide synchronously to the opposite side, thereby compressing the limiting spring. Then, the lithium battery of the power tool is inserted into the charging slot, and the control lever is released. At this time, the limiting spring is not affected by external force, causing the moving blocks and clamping blocks on both sides to slide synchronously to the opposite side. The clamping blocks hold the lithium battery. By setting an anti-drop mechanism, the clamping blocks hold and fix the surface of the lithium battery inserted into the charging slot under the influence of the elasticity of the limiting spring, thereby improving the stability of the lithium battery during the charging process and preventing it from falling off.

[0018] (2) The charging anti-drop structure of the power tool charger is that by pressing down the positioning rod, the positioning rod rotates at one end of the connecting rod, and the other end of the positioning rod separates from the tooth groove on the surface of the ratchet. The plug is then pulled out to pull out the charging cable, thus realizing the subsequent charging operation. After charging is completed, the rotating block is directly rotated to drive the take-up rod and take-up reel to rotate, so that the charging cable is put into the inside of the charger body, preventing the charging cable from being scattered outside. The length of the charging cable is positioned by the positioning component to prevent long charging cables from being exposed outside. The take-up component can quickly retract the charging cable into the inside of the charger body after charging is completed, preventing the charging cable from being scattered outside.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] Example 1

[0027] A charging anti-drop structure for an electric tool charger includes a charger body 1 and a plug 2. The charger body 1 has a cable winding mechanism 3 inside and an anti-drop mechanism 4 inside. The anti-drop mechanism 4 includes:

[0028] The anti-detachment component 41 includes a sliding rod 411 slidably installed inside the charger body 1. One end of the sliding rod 411 is rotatably connected to a rotating rod 412, and the other end of the sliding rod 411 is fixedly connected to a moving block 413. A limit spring 414 is fixedly connected to one side of the moving block 413. One end of the limit spring 414 is fixedly connected to the inner wall of the charger body 1, and a clamping block 415 is fixedly connected to the other side of the moving block 413. The surface of the clamping block 415 is slidably connected to the inside of the charger body 1.

[0029] The control component 42 is located inside the charger body 1.

[0030] Limiting sliders are installed on both sides of the movable block 413. The limiting sliders slide inside the charger body 1 to limit the sliding of the movable block 413, so that the movable block 413 can only slide left and right. The limiting spring 414, without the influence of external force, allows one end of the clamping block 415 to slide through into the interior of the charging slot 6.

[0031] In this embodiment, the control component 42 includes a control rod 421 that is slidably mounted on the top of the charger body 1. A control block 422 is fixedly connected to the bottom end of the control rod 421. The interior of the control block 422 is rotatably connected to one end of the rotating rod 412. A limit rod 423 is fixedly connected to the bottom end of the control block 422. The surface of the limit rod 423 is slidably connected to the interior of the charger body 1.

[0032] The limiting rod 423 slides inside the charger body 1 to limit the sliding of the control block 422, so that the control block 422 will not deviate when it slides up and down.

[0033] In this embodiment, the take-up mechanism 3 includes:

[0034] The cable take-up assembly 31 includes a take-up rod 311 rotatably installed inside the charger body 1, a take-up reel 312 fixedly connected to the surface of the take-up rod 311, a ratchet gear 313 fixedly connected to the surface of the take-up rod 311, and a rotating block 314 fixedly connected to one end of the take-up rod 311.

[0035] Positioning component 32 is disposed inside the charger body 1.

[0036] One end of the retractor 311 extends through to the outside of the charger body 1 and is equipped with a rotating block 314.

[0037] In this embodiment, the positioning component 32 includes a connecting rod 321 installed on the inner wall of the charger body 1. One end of the connecting rod 321 is rotatably connected to a positioning rod 322. One end of the positioning rod 322 extends through to the outside of the charger body 1. The surface of the positioning rod 322 is slidably connected to the inside of the charger body 1. The other end of the positioning rod 322 is in contact with the surface of the ratchet 313. A positioning spring 323 is fixedly connected to the top of the positioning rod 322. One end of the positioning spring 323 is fixedly connected to the top of the inner cavity of the charger body 1.

[0038] A positioning block is installed at the other end of the positioning rod 322. The positioning block is an arc-shaped block that fits into the tooth groove on the surface of the ratchet 313, so that the ratchet 313 can only rotate freely counterclockwise. When rotating clockwise, the positioning rod 322 needs to be rotated first to separate the positioning block from the surface of the ratchet 313. The positioning spring 323 will keep the positioning block installed at the other end of the positioning rod 322 in contact with the tooth groove on the surface of the ratchet 313 when it is not affected by external force.

[0039] In this embodiment, a charging cable 5 is fixedly connected to one side of the plug 2, one end of the charging cable 5 is fixedly connected to the surface of the cable reel 312, and the surface of the charging cable 5 is slidably connected to the interior of the charger body 1.

[0040] In this embodiment, a charging slot 6 is provided on the top of the charger body 1, and a charging indicator light 7 is installed on the top of the charger body 1.

[0041] The anti-drop-off structure of this power tool charger works by pressing the control lever 421, which causes the control block 422 to slide downwards. The sliding of the control block 422 causes one end of the rotating rod 412 to rotate inside the control block 422, and the other end of the rotating rod 412 to rotate at the other end of the sliding rod 411. This causes the sliding rod 411 to slide inside the charger body 1. The sliding of the sliding rod 411 causes the moving blocks 413 and clamping blocks 415 on both sides to slide synchronously to opposite sides, thereby compressing the limiting spring 414. Then, the lithium battery of the power tool is inserted into the charging slot 6, and the control lever 421 is released. At this time, the limiting spring 414, without the influence of external force, causes the moving blocks 413 and clamping blocks 415 on both sides to slide synchronously to opposite sides, clamping the lithium battery through the clamping blocks 415. By setting the anti-drop-off mechanism 4, the clamping blocks 415 clamp and fix the surface of the lithium battery inserted into the charging slot 6 under the influence of the elasticity of the limiting spring 414, thereby improving the stability of the lithium battery during charging and preventing it from falling off.

[0042] The charging anti-drop structure of this power tool charger works by pressing down on the positioning rod 322, causing it to rotate at one end of the connecting rod 321. The other end of the positioning rod separates from the tooth groove on the surface of the ratchet 313, and the plug 2 is pulled out to remove the charging cable 5, enabling subsequent charging operations. After charging is complete, the rotating block 314 drives the take-up rod 311 and take-up reel 312 to rotate, bringing the charging cable 5 into the charger body 1, preventing the charging cable 5 from scattering outside. The positioning component 32 positions the length of the charging cable 5, preventing longer charging cables from being exposed outside. The take-up component 31 can also quickly retract the charging cable 5 into the charger body 1 after charging is complete, preventing the charging cable 5 from scattering outside.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0044] During operation, firstly, pressing the control lever 421 causes the control block 422 to slide downwards. The sliding of the control block 422 causes one end of the rotating rod 412 to rotate inside the control block 422, and the other end of the rotating rod 412 to rotate at the other end of the sliding rod 411. This causes the sliding rod 411 to slide inside the charger body 1. The sliding of the sliding rod 411 causes the moving blocks 413 and clamping blocks 415 on both sides to slide synchronously to opposite sides, thereby compressing the limiting spring 414. Then, the lithium battery of the power tool is inserted into the charging slot 6, and the control lever 421 is released. At this point, the limiting spring 414, unaffected by external force, causes... The moving blocks 413 and clamping blocks 415 on both sides slide synchronously to the opposite side. The clamping blocks 415 clamp the lithium battery to keep it stable during charging and prevent it from falling off. Then, by pressing down on the positioning rod 322, the positioning rod 322 rotates at one end of the connecting rod 321. The other end of the positioning rod separates from the tooth groove on the surface of the ratchet 313 and pulls the plug 2 to pull out the charging cable 5, realizing the subsequent charging operation. After charging is completed, the rotating block 314 drives the take-up rod 311 and take-up reel 312 to rotate, so that the charging cable 5 is put into the inside of the charger body 1, preventing the charging cable 5 from being scattered outside.
