Description

Technical Field

[0001] This utility model relates to the field of circuit boards, and more specifically, to a single-board portable tool. Background Technology

[0002] When potting heavy printed circuit boards (PCBs) with large, heavy components such as transformers, inductors, and heat sinks, the PCB is usually placed upside down (components facing down) into the potting tank to ensure uniform and sufficient potting. Since heavy PCBs often weigh over 10kg and have a width exceeding 134mm, operators cannot hold them stably with one hand, nor can they ensure the PCB remains horizontal when carrying it with both hands. This makes it easier for components to scrape against the potting tank and damage the PCB components when placed in the potting tank. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a single-board handheld tool that not only enables horizontal clamping and placement of circuit boards to avoid damage to circuit board components, but also has a simple structure and is easy to manufacture and operate.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a single-board carrying fixture is constructed, including a first fixture assembly, a second fixture assembly, an elastic assembly, and a bearing assembly; the first fixture assembly includes a first handle and a first lifting hook, and the second fixture assembly includes a second handle and a second lifting hook; the first sides of the first handle and the second handle are movably connected through the bearing assembly, and the second sides of the first handle and the second handle are elastically connected through the elastic assembly, so that when the first handle and the second handle move towards each other under the drive of an external force, the first lifting hook and the second lifting hook close together, and when the external force is withdrawn, the first lifting hook and the second lifting hook separate under the action of gravity.

[0005] In the single-board carrying fixture described in this utility model, the first handle includes a first gripping part, a snap-fit ​​part disposed at a first end of the first gripping part, and a support part disposed at a second end adjacent to the first gripping part. The first lifting hook includes a first mounting portion and a first hook-shaped portion; the first hook-shaped portion extends downward from the second end of the first mounting portion, and the first end of the elastic component is fixed to the first end of the first mounting portion.

[0006] In the single-board carrying fixture of this utility model, the first gripping part is a U-shaped gripping part, the snap-fit ​​part is a U-shaped snap-fit ​​part, and the supporting part extends from the side wall of the U-shaped gripping part away from the snap-fit ​​part toward the snap-fit ​​part.

[0007] In the single-board carrying fixture of this utility model, the first hook-shaped part includes a first vertical part and a first horizontal part. The first vertical part extends downward from the second end of the first mounting part, and the first horizontal part extends horizontally from the first vertical part toward the first end of the first gripping part.

[0008] In the single-board hand-held fixture of this utility model, the first horizontal part and the first mounting part are respectively wrapped with rubber layers.

[0009] In the single-board carrying fixture of this utility model, the second handle includes a second gripping part and a second connecting part; the first end of the second gripping part is fixed to the support part of the first handle, and the second end of the second gripping part is connected to the first end of the second connecting part; The second lifting hook includes a second mounting portion and a second hook-shaped portion; the second end of the second connecting portion is connected to the first end of the second mounting portion, and the second hook-shaped portion extends downward from the second end of the second mounting portion; The second connecting part is movably engaged with the U-shaped snap-fit ​​part of the first handle part through the bearing assembly; The second end of the elastic component is fixed at a position adjacent to its first end and directly opposite to the first mounting portion of the first lifting hook.

[0010] In the single-board carrying fixture of this utility model, the second gripping part includes a second horizontal part and a second U-shaped part fixed in the middle of the second horizontal part. The first end of the second horizontal part is fixed on the support part of the first handle member, and the second end of the second horizontal part is connected to the first end of the second connecting part.

[0011] In the single-board carrying fixture described in this utility model, the second U-shaped part is directly opposite the first gripping part, and the second U-shaped part is wrapped with a rubber layer.

[0012] In the single-board carrying fixture of this utility model, bearing holes are provided on both the second connecting part and the U-shaped snap-fit ​​part. The second connecting part is snapped into the opening of the U-shaped snap-fit ​​part, and the bearing assembly passes through the bearing hole.

[0013] In the single-board carrying fixture of this utility model, the distance between the second U-shaped part and the first gripping part is 40~50mm, the first hook-shaped part and the second hook-shaped part are provided with protrusions facing each other on one side, the height of the protrusions is 3~5mm and they are chamfered, and the protrusions are covered with a rubber layer.

[0014] The single-board carrying fixture of this invention allows for convenient horizontal clamping of the printed circuit board from the side when the first and second lifting hooks are separated. Applying an external force to the first and second handles controls the first and second lifting hooks to close, maintaining the horizontal clamping of the printed circuit board and facilitating its movement. Removing the external force allows the first and second lifting hooks to separate again, horizontally placing the printed circuit board into the potting mix. The entire process involves horizontal clamping, facilitating precise positioning and minimizing damage to the components on the circuit board. The clamping is achieved by applying an external force, and release is achieved by gravity upon removing the force, making the entire operation simple. Furthermore, this single-board carrying fixture is manufactured from only a few components, making it easy to produce. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Figure 1 This is a structural schematic diagram of the single-board hand-held tool of this utility model from the first angle. Figure 2 This is a structural schematic diagram of the single-board hand-held tool of this utility model from a second angle. Figure 3 This is a structural schematic diagram of the single-board hand-held tool of this utility model from the third angle.

[0018] like Figures 1-3 As shown, the single-board carrying fixture includes a first fixture assembly 100, a second fixture assembly 200, an elastic assembly 300, and a bearing assembly 400. The first fixture assembly 100 includes a first handle 110 and a first lifting hook 120, and the second fixture assembly 200 includes a second handle 210 and a second lifting hook 220. The first sides of the first handle 110 and the second handle 210 are movably connected via the bearing assembly 400, and the second sides of the first handle 110 and the second handle 210 are elastically connected via the elastic assembly 300. This allows the first lifting hook 120 and the second lifting hook 220 to close when the first handle 110 and the second handle 210 move towards each other under an external force, and to separate under gravity when the external force is withdrawn.

[0019] like Figures 1-3 As shown, the first handle 110 is located above the second handle 200. When it is necessary to clamp heavy plate-shaped items, such as heavy printed circuit boards, only the first handle 100 can be gripped. At this time, under the action of the elastic component 300 and its own weight, the first hook 120 and the second hook 220 naturally open, allowing the heavy plate-shaped item to be horizontally inserted from the side. Then, simply insert a single palm into the second handle 210 from above and close the palm. The force applied by the palm overcomes the elasticity of the spring component 300, causing the first handle 110 and the second handle 200 to close (i.e., the first handle 110 and the second handle 210 move towards each other under the drive of an external force). In this way, the lever mechanism formed by the first handle 110, the second handle 210, and the bearing component 400 drives the first hook 120 and the second hook 220 to close, thereby horizontally clamping and moving the heavy plate-shaped item, such as a heavy printed circuit board. When it is necessary to lower the heavy printed circuit board, simply release your hand to remove the external force. The spring assembly 300 will then return to its original position, and the first hook 120 and the second hook 220 will separate under the influence of gravity. At this point, the heavy printed circuit board can be lowered horizontally.

[0020] The single-board carrying fixture of this invention allows for convenient horizontal clamping of the printed circuit board from the side when the first and second lifting hooks are separated. Applying an external force to the first and second handles controls the first and second lifting hooks to close, maintaining the horizontal clamping of the printed circuit board and facilitating its movement. Removing the external force allows the first and second lifting hooks to separate again, horizontally placing the printed circuit board into the potting mix. The entire process involves horizontal clamping, facilitating precise positioning and minimizing damage to the components on the circuit board. The clamping is achieved by applying an external force, and release is achieved by gravity upon removing the force, making the entire operation simple. Furthermore, this single-board carrying fixture is manufactured from only a few components, making it easy to produce.

[0021] Figure 4 This is a schematic diagram of the structure of the first tooling component of the single-board portable tooling of this utility model. Figure 4 This is a structural schematic diagram of the second tooling component of the single-board portable tooling of this utility model. (See diagram below.) Figure 4 As shown, the first handle 110 includes a first grip portion 111, a snap-fit ​​portion 112 disposed at a first end of the first grip portion 111, and a support portion 113 disposed adjacent to a second end of the first grip portion 111. The first lifting hook 120 includes a first mounting portion 121 and a first hook-shaped portion 122; the first hook-shaped portion 122 extends downward from the second end of the first mounting portion 121, and the first end of the elastic component 300 is fixed to the first end of the first mounting portion 121. Figure 4 As shown, the first gripping part 111 is a U-shaped gripping part, the locking part 112 is a U-shaped locking part 112, and the support part 113 extends from the side wall of the U-shaped gripping part away from the locking part 112 toward the U-shaped locking part 112.

[0022] The first hook-shaped portion 122 is an L-shaped hook-shaped portion, which includes a first vertical portion 1221 and a first horizontal portion 1222. The first vertical portion 1221 extends downward from the second end of the first mounting portion 121, and the first horizontal portion 1222 extends horizontally from the first vertical portion 1221 toward the first end of the first gripping portion 111. Rubber layers may be wrapped around the first horizontal portion 1222 and the first mounting portion 121, respectively.

[0023] like Figure 5As shown, the second handle 210 includes a second gripping portion 211 and a second connecting portion 212; the first end of the second gripping portion 211 is fixed to the support portion 113 of the first handle 110, and the second end of the second gripping portion 211 is connected to the first end of the second connecting portion 212; the second hook 220 includes a second mounting portion 221 and a hook-shaped portion 222; the second end of the second connecting portion 212 is connected to the first end of the second mounting portion 221, and the second hook-shaped portion 222 extends downward from the second end of the second mounting portion 221; the second connecting portion 212 of the second handle 210 is movably engaged with the U-shaped snap-fit ​​portion 112 of the first handle 110 via the bearing assembly 400. Figure 5 As shown, bearing holes are provided on both the second connecting portion 212 and the U-shaped snap-fit ​​portion 112, and the second connecting portion 212 snaps into the opening of the U-shaped snap-fit ​​portion 112. The bearing assembly 400 passes through the bearing holes located in the second connecting portion 212 of the second handle member 210 and the U-shaped snap-fit ​​portion 112 of the first handle member 110, thus serving as the fulcrum of the entire single-board carrying fixture. It hinges the second handle member 210 and the first handle member 110 together with the second lifting hook member 220 and the first lifting hook member 120 respectively connected to them, allowing them to open and close like scissors.

[0024] The second end of the elastic component 300 is fixed to the second grip portion 211 near its first end and opposite the first mounting portion 121 of the first lifting hook 120. The second grip portion 211 includes a second horizontal portion 2111 and a second U-shaped portion 2112 fixed to the middle of the second horizontal portion 2111. The first end of the second horizontal portion 2111 is fixed to the support portion 113 of the first handle 110, and the second end of the second horizontal portion 2111 connects to the first end of the second connecting portion 212. The second U-shaped portion 2112 faces the first grip portion 111, and a rubber layer is wrapped around the second U-shaped portion 2112. The second U-shaped portion 2112 and the first grip portion 111 are provided for the operator to hold, thus the addition of a wear-resistant and non-slip rubber layer increases grip comfort and stability.

[0025] In this invention, the first hook-shaped portion 122 and the second hook-shaped portion 222 face each other, thereby supporting and clamping the printed circuit board from its bottom edge. Therefore, the side of the first hook-shaped portion 122 and the second hook-shaped portion 222 that contacts the printed circuit board is preferably covered with a wear-resistant and anti-slip rubber layer.

[0026] In a preferred embodiment of this utility model, the first hook-shaped portion 122 and the second hook-shaped portion 222 are provided with protrusions 311 facing each other. The height of the protrusions 311 is 3~5mm and has a chamfer. More preferably, the height of the protrusions 311 is 4mm. The side of the protrusions facing the printed circuit board is also covered with wear-resistant and anti-slip rubber and designed with guide chamfers. When the first lifting hook 120 and the second lifting hook 220 close and clamp the printed circuit board, the protrusions just abut against the bottom edge of the printed circuit board, and their chamfered structure helps guide the printed circuit board into the correct clamping position.

[0027] In a preferred embodiment of the present invention, the first tooling assembly 100 and the second tooling assembly 200 can be integrally formed.

[0028] In a preferred embodiment of this utility model, the first tooling assembly 100 and the second tooling assembly 200 can be made from magnesium alloy plates that are 10mm wide and 5mm thick, respectively, through cutting, bending, and drilling, thus combining lightweight and high strength. Of course, they can also be assembled from any suitable components, all of which fall within the protection scope of this utility model.

[0029] Figure 6 This is a schematic diagram illustrating the lifting effect of the single-plate hand-held fixture of this utility model. The following will combine... Figures 1-6 The principle of the single-board portable tool of this utility model is explained as follows.

[0030] In its natural state, under the action of the spring assembly 300, the first lifting hook 120 and the second lifting hook 220 are in an open state, making it easy to slip the printed circuit board in from the side.

[0031] In the clamping state, the operator grips the first handle 110 and the second handle 210 with their hands, which can grip the second U-shaped part 2112 and the first gripping part 111, overcoming the elastic force of the spring assembly 300. The lever mechanism formed by the first handle 110, the second handle 210 and the bearing assembly 400 drives the first lifting hook 120 and the second lifting hook 220 to close, so that the rubber-coated first hook-shaped part 122 and the second hook-shaped part 222 and the boss 311 firmly clamp the two sides and the bottom of the printed circuit board.

[0032] Once the circuit board is aligned and clamped, it can be lifted. Thanks to the stable and reliable clamping force provided by the fixture, the operator can easily move the circuit board above the potting mix and, utilizing the stability of the fixture, precisely align it with the slot before placing it in.

[0033] In the released state, once the printed circuit board is in place, the operator only needs to release the handle. Under the restoring force of the spring assembly, the first lifting hook 120 and the second lifting hook 220 automatically open, thereby disengaging from the printed circuit board and achieving a quick and interference-free release.

[0034] In operation, the operator can hold the first handle 110 and the second handle 210 with one hand, thus gripping the second U-shaped part 2112 and the first gripping part 111. The operator then inserts the opened first lifting hook 120 and the second lifting hook 220 from both sides of the printed circuit board, ensuring the boss 311 is slightly lower than the bottom edge of the printed circuit board. By gripping the handle firmly and overcoming the tension of the spring assembly, the first hook-shaped part 122 and the second hook-shaped part 222 of the first lifting hook 120 and the second lifting hook 220, along with the boss 311, tightly clamp the two edges of the printed circuit board. Lifting the fixture stabilizes the printed circuit board, transporting it above the potting groove. Using the rigidity of the fixture as a guide, the board is easily aligned with the groove opening and placed inside. Once the printed circuit board is confirmed to be in place, the operator releases the handle. The first lifting hook 120 and the second lifting hook 220 automatically open under the action of the spring assembly 300, disengaging from the printed circuit board and completing the release process. This procedure enables the lifting and placing of the printed circuit board.

[0035] The single-board hand-held fixture of this utility model has the following beneficial effects: 1. Labor-saving and efficient: Utilizing the lever principle, the operator only needs a small grip force to lift heavy objects weighing over 10kg, greatly reducing labor intensity and improving handling and placement efficiency. 2. Effective protection: The wear-resistant and anti-slip rubber layer of the first hook-shaped part 122, the second hook-shaped part 222, and the boss 311 provides sufficient friction to prevent slippage and avoids direct contact between metal parts and the printed circuit board, effectively preventing scratches and pressure damage to the board surface and components. 3. Simple operation: The "one-grip-lift, one-release-put" operation logic is extremely simple, requiring no complex training, reducing operational difficulty and error rate. 4. Lightweight and sturdy structure: Made of lightweight, high-strength materials such as magnesium alloy, it ensures load-bearing capacity while being lightweight, further reducing the burden on the operator.
