DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0030] As described above, the charger of the electric tool is vulnerable to damage by accident when charging at the construction site, which brings safety hazards to the charging work of the charger. At present, there is a lack of a device on the market that can solve the protection problem of the charger of the electric tool during charging. In view of this, the utility model provides an electric tool charger protection structure, which solves the above problems. The utility model is solved by the following way.

[0031] Embodiment one:

[0032] Please refer to the drawings in the description Figure 1 As shown in the figure, the embodiment discloses an electric tool charger protection structure, which comprises a shell 1, a movable seat 3 and an adjusting structure. The top of the shell 1 has an open mouth for taking or operating the charger of the electric tool. The shell 1 is provided with a notch 2, which is arranged at the front of the shell 1 and has an overall inverted U-shaped structure design. The two sides and the top of the front of the shell 1 are opened. The movable seat 3 is arranged in the interior of the shell 1, and the movable seat 3 is used for bearing the charger and can be lifted in the shell 1. The adjusting structure is arranged in the notch 2 and is used for connecting the shell 1 and the movable seat 3 and adjusting the lifting of the movable seat 3.

[0033] The utility model is designed by the above structure, the lifting of the movable seat 3 in the shell 1 can be controlled by controlling the adjusting structure. When charging is needed, the charger in the movable seat 3 is exposed by lifting the movable seat 3, so that taking or operating is facilitated. When charging is not needed, the control structure and the shell 1 form a storage space for storing the charger, which is convenient for carrying and protection.

[0034] Example 2:

[0035] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 2 As shown in this second embodiment, the adjustment structure includes a first sector gear 4 and a second sector gear 5 that mesh with each other. Both the first sector gear 4 and the second sector gear 5 are rotatably connected to the outer casing 1 via a plug shaft 6. The first sector gear 4 and the second sector gear 2 are also fixedly connected to a misaligned rotating rod 1 7 and a rotating rod 3 8, which allows the rotating rod 1 7 and the rotating rod 3 8 to rotate synchronously when the first sector gear 4 or the second sector gear 2 rotates.

[0036] Next, a top sealing plate 30 is rotatably connected to the end of rotating rod 7 away from the insertion shaft 6. Rotating rods 10 are provided on the opposite sides of rotating rods 7, with one end of each rotating rod 10 rotatably connected to the top sealing plate 30 and the other end rotatably connected to the outer casing 1. Because the top sealing plate 30 is connected to both rotating rod 7 and rotating rod 10, it has two connection points, preventing it from rotating around any single connection point and ensuring its balance. A rotating rod 9 is rotatably connected to the end of rotating rod 3 8 away from the insertion shaft 6, and the end of rotating rod 4 9 away from rotating rod 3 8 is rotatably connected to the movable seat 3.

[0037] Therefore, in the specific implementation of this second embodiment, the appendix is ​​used. Figure 2 Taking the state in the example as an example, if the top sealing plates 30 on both sides are pushed closer to each other, then... Figure 2 Sector gear 4 rotates counterclockwise, while sector gear 5 rotates clockwise due to meshing. Simultaneously, the rotating rods 8 on both sides also rotate in similar motions. The circular rotation of rod 8 creates a vertical displacement difference between its top and the connecting part of rotating rod 9. This displacement difference causes rotating rod 9 to move, thereby lowering the movable seat 3. When the top sealing plates 30 on both sides are pressed together, the movable seat 3 descends to its lowest point, completing its storage. At this point, the two pressed-together top sealing plates 30 cover the top opening of the outer casing 1, acting as a lid.

[0038] To raise the movable seat 3, pull any one of the top sealing plates 30 in the opposite direction to the other. The adjusting structure will then move in the opposite direction, thus raising the movable seat 3. When the edge of the rotating rod 10 is close to the edge of the slot 2, the top sealing plate 30 moves to the outermost edge, and the movable seat 3 rises to its highest point.

[0039] Of course, it needs to be explained here that when the charger is carried on the movable seat 3, the overall weight is large, under the action of gravity, it is very likely to drive the rotating rod three 8 and the rotating rod four 9 to rotate reversely, so that the two side top sealing plates 30 are close, and finally the movable seat 3 falls into the outer shell 1, therefore, in order to avoid this situation, the sum of the weights of the two side top sealing plates 30 is designed to be greater than the sum of the weights of the movable seat 3 and the charger, when the edge of the rotating rod two 10 is close to the edge of the slot 2, the edge of the slot 2 bears part of the weight difference, so as to achieve balance.

[0040] It also needs to be explained here that when the movable seat 3 is lowered to the lowest position in the outer shell 1, the shaft of the movable seat 3 and the rotating rod four 9 is rotated, and the line in the horizontal direction (the vertical line of the movement axis of the movable seat 3 is attached Figure 2 As an example, the line in the horizontal direction is the vertical line of the movement axis of the movable seat 3), should be higher than the line in the horizontal direction of the shaft of the rotating rod four 9 and the rotating rod three 8. This is to ensure that the adjusting assembly will not be unable to run due to movement interference during the adjusting process.

[0041] Embodiment three:

[0042] Based on the above embodiment, in order to further clearly and completely explain the technical scheme therein, the utility model also provides embodiment three. As Figure 3 And Figure 4 Shown in embodiment three, the movable seat 3 has a vertical part and a flat part, which are arranged vertically and constitute an L-shaped structure as shown in Figure 3 The vertical part is connected with the adjusting structure, and the flat part is provided with a wire slot 11 and a through opening one 12 connected with the wire slot 11. When the charger of the electric tool is placed on the flat part, the power cord of the electric tool charger can enter the wire slot 11 from any position of the wire slot 11 to complete the wire laying, avoiding the pressure of the electric tool charger on the power cord and causing damage. At the same time, the through opening one 12 is used to pass through the charging head of the electric tool charger, so that it can be inserted into the socket at the construction site.

[0043] In order to make the charger of the electric tool more stable, the embodiment three is further provided with a silica gel fixing part 13 outside the wire slot 11 and the through opening one 12, which is located on the flat part and is annularly arranged, and the inner ring of the annular part is matched with the shape of the charger of the electric tool. In use, the charger is placed in the silica gel fixing part 13 and is attached to the inner ring of the silica gel fixing part 13. The silica gel fixing part 13 can protect and buffer the charger of the electric tool due to its silica gel material, ensuring the safety of the charger during charging.

[0044] In order to ensure the stability of the movable seat 3 during the lifting process, the third embodiment is provided with positioning grooves 14 on both sides of the flat part. The sliding rails 17 are slidably connected in the positioning grooves 14, and the top of the sliding rails 17 on the same side is connected by the limiting strips 18. When the flat part touches the limiting strips 18, the movable seat 3 moves to the top end. At the same time, the partition plate 15 is fixed in the shell 1, and the sliding rails 17 are fixed on the inner wall of the shell 1. When the flat part touches the partition plate 15, the movable seat 3 moves to the bottom end.

[0045] The partition plate 15 is provided with a through hole two 16 corresponding to the through hole one 12, and the shell 1 is provided with a socket opening 27 away from the slot 2. In use, the plug of the electric tool charger passes through the through hole one 12 and the through hole two 16 in turn, and finally passes through the socket opening 27 to be inserted into the socket, so as to realize charging. Because the municipal socket is now protruded from the wall surface by a small part of the shell, and the size of this part of the shell is produced by manufacturers according to the national general standard (for example: 86 type, 118 type, 120 type and 146 type), therefore, the socket opening 27 is designed to meet the general standard size. This makes it possible to use the socket opening 27 to buckle the electric tool charger protection structure designed by the utility model on the municipal socket, so as to charge. Of course, the protection structure can also be placed on the support, and the charging head is extended out of the socket opening 27 to charge. The shell 1 is also provided with an operating door 28, which is used to insert the operating tool or hand into it to plug or unplug the plug of the charger. The bottom of the shell 1 is also provided with a plurality of ventilation holes 29, and the ventilation holes 29 are provided with dust screens. The dust on the construction site can be filtered to a certain extent.

[0046] Embodiment four:

[0047] Based on the above embodiments, in order to further clearly and completely explain the technical solutions, the utility model also provides an embodiment four, as shown in Figure 2 , Figure 5 and Figure 6 , in the embodiment four, the fan gear one 4 is provided with two symmetrical through holes one 19, the shell 1 is provided with a through hole two 20 matched with the through hole one 19, and the outer wall of the shell 1 is provided with a limiting structure, which includes a handle plug-in bolt 21 inserted into the through hole two 20. In use, the bolt 21 is inserted into one of the through holes one 19 on the fan gear one 4, so as to fix the position of the fan gear one 4. This makes the limiting structure better fix the position of the adjusting structure when the adjusting structure reaches the specified position.

[0048] Then, the outside sleeve of the latch 21 is provided with a spring 22, both ends of the spring 22 are respectively provided with a limiting plate one 23 and a limiting plate two 24, the outside of the latch 21 is provided with a limiting shell 26 with a through slot 25, the limiting plate two 24 is located in the through slot 25 and connected with the latch 21, and the limiting plate one 23 is located in the through slot 25 and connected with the through slot 25. When it is needed to change the state of the movable seat 3 (to make it rise or fall), before adjusting the adjusting structure, the user should first pull the handle of the latch 21, the latch 21 is moved away from the through hole one 19, the limiting plate two 24 is close to the limiting plate one 23, and the spring 22 is compressed and deformed. When the latch 21 is completely separated from the through hole one 19, the sector gear one 4 can rotate, at this time, the user can release the handle of the latch 21, the latch 21 is reset under the deformation force of the spring 22 and abuts against the plate surface of the sector gear one 4, with the continuous rotation of the sector gear one 4, when the latch 21 coincides with another through hole one 19, the latch 21 is immediately inserted into the through hole one 19, and the limiting is completed.

[0049] The latch 21 needs to be made of a material with certain strength and brittleness, for example, polyoxymethylene or hard plastic, which has certain rigidity under daily use and can complete the limiting work. When the device body is impacted during use, especially when the top sealing plate 30 is impacted, the two side top sealing plates 30 will move towards each other, at this time, the latch 21 will be subjected to a clamping force due to the misalignment of the through hole one 19 on the sector gear one 4 and the through hole two 20 on the shell 1, and the polyoxymethylene or hard plastic is brittle, so when the clamping force is subjected, the latch 21 will be broken, so as not to affect the rotation of the sector gear one 4. It is also because of this that when the device as a whole is subjected to impact force in the use site, the movable seat 3 will be immediately driven to return to the inside of the shell 1, thereby protecting the electric tool charger and ensuring that the charger is not damaged by external impact.

[0050] In summary, based on the above embodiments, the electric tool charger protection structure has the following advantages, including but not limited to:

[0051] The adjusting structure is used for adjusting the lifting of the movable seat 3 in the shell 1, so that the charger is lifted for charging when the charger needs to be charged, and the charger is lowered for storage when the charger does not need to be charged.

[0052] The charger is arranged on the movable seat 3, the wire slot 11 on the movable seat 3 is used for placing the power cord of the charger, the through hole one 12 and the through hole two 16 are communicated with each other, so that the charging head of the charger and the power cord can pass through the above-mentioned holes and finally pass through the socket hole 27 and are inserted into the socket, the power cord and the charging head of the charger are protected by the internal wire, so that the damage from the construction site is reduced.

[0053] The utility model discloses a limit structure, through the way of limiting the through -hole one 19 to plug -in bolt 21, can fix the position of the movable seat 3 after adjusting the adjusting structure, thereby make the load of movable seat 3 more stable, simultaneously, the bolt 21 can break, when the whole equipment or top sealing plate 30 suffers the impact, the top sealing plate 30 is stressed, drives the fan gear one 4 fast rotation, grinds the bolt 21, can fastly recover the movable seat 3 and the charger on it to the inner shell, for protecting the charger from the impact damage.
