Description

Technical Field

[0001] The invention is used in the field of automobile accessories, and in particular relates to a multi-row fuse extraction tool. Background Art

[0002] When a car needs to replace a wiring harness with a fuse, the new wiring harness generally does not come with a fuse. At this time, you need to pull out all the fuses (about 30) from the old fuse box at once and install them in the new fuse box. Sometimes, in order to prevent the vehicle from losing power, you also need to pull out some fuses to cut off the power.

[0003] At present, the general method of removing fuses is to use the original clips to remove them one by one. The original clips are relatively small and inconvenient to pull out, and are easy to fall and damage. If they are damaged, you must find another tool to work.

[0029] In the present invention, unless otherwise clearly defined, the words "set", "install", "connect" and the like should be understood in a broad sense, for example, they can be directly connected or indirectly connected through an intermediate medium; they can be fixedly connected or detachably connected or integrally formed; they can be mechanically connected or electrically connected or able to communicate with each other; they can be the internal connection of two elements or the interaction relationship between two elements. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0030] See also Figure 1 , Figure 2 The embodiment of the present invention provides a multi-row fuse extraction tool, comprising a first clamping arm 1 and a second clamping arm 2, the first clamping arm 1 and the second clamping arm 2 are connected by a first elastic connecting portion 3, a first movable gap is formed between the first clamping arm 1 and the second clamping arm 2, the first elastic connecting portion 3 is provided with a first linkage arm 4 and a second linkage arm 5 extending into the first movable gap, a gap is left between the first linkage arm 4 and the second linkage arm 5, the first linkage arm 4 is closer to the first clamping arm 1 than the second linkage arm 5, and the second linkage arm 5 is closer to the second clamping arm 2 than the first linkage arm 4, the ends of the first clamping arm 1, the first linkage arm 4, the second linkage arm 5 and the second clamping arm 2 are substantially flush, the first linkage arm 4 cooperates with the first clamping arm 1 to form a first clamping opening that can be opened and closed, the second linkage arm 5 cooperates with the second clamping arm 2 to form a second clamping opening that can be opened and closed, the first linkage arm 4 is connected to the second clamping arm 2 by a first connecting column 6 to realize linkage during the opening and closing process, and the second linkage arm 5 is connected to the first clamping arm 1 by a second connecting column 7 to realize linkage during the opening and closing process. The first elastic connection part 3 may be made of plastic material to ensure that the first elastic connection part 3 has good physical elasticity.

[0031] See also Figure 3 , Figure 4 Specifically, when in use, the end of the extraction tool is inserted into the fuse box, and a force is applied to the first clamping arm 1 and the second clamping arm 2, so that the first clamping arm 1 and the second clamping arm 2 are opened. During this time, the first linkage arm 4 is linked with the second clamping arm 2 through the first connecting column 6, away from the first clamping arm 1, so that the first clamping opening is opened, and the second linkage arm 5 is linked with the first clamping arm 1 through the second connecting column 7, away from the second clamping arm 2, so that the second clamping opening is opened. Then, the fuse 8 is clamped into the first clamping opening and the second clamping opening, and the fuse 8 is pulled out. Finally, a force is applied to the first clamping arm 1 and the second clamping arm 2, so that the first clamping arm 1 and the second clamping arm 2 are opened again, and the fuse falls out.

[0032] In the embodiment of the present invention, two clamping openings, namely the first clamping opening and the second clamping opening, are defined in the first movable gap by the first clamping arm 1, the first linkage arm 4, the second linkage arm 5 and the second clamping arm 2, so that two rows of fuses 8 can be pulled out simultaneously. The above technical solution solves the problem of opening and clamping multiple rows of fuses at the same time through ingenious design, greatly improving work efficiency.

[0033] In some embodiments, in order to ensure that the clamping opening can exert a more reliable clamping effect on the fuse, see Figure 1 , Figure 2 , the first clamping arm 1 is provided with a first clamping protrusion 9 for clamping the fuse 8 at one end away from the first elastic connection part 3, the first clamping protrusion 9 faces the first linkage arm 4, the first linkage arm 4 is provided with a second clamping protrusion 10 for clamping the fuse at one end away from the first elastic connection part 3, the second clamping protrusion 10 faces the first clamping arm 1; the second clamping arm 2 is provided with a third clamping protrusion for clamping the fuse at one end away from the first elastic connection part 3, the third clamping protrusion faces the second linkage arm 5, the second linkage arm 5 is provided with a fourth clamping protrusion for clamping the fuse at one end away from the first elastic connection part 3, the fourth clamping protrusion faces the second clamping arm 2. In other words, each clamping opening is provided with relatively arranged protrusions to hook the fuse from the bottom during the process of pulling out the fuse.

[0034] Furthermore, each clamping opening is provided with one or more pairs of clamping protrusions, for example Figure 5 , Figure 6 In some embodiments shown, the end of the first clamping arm 1 is provided with multiple groups of first clamping protrusions 9, which are arranged in a row on one side of the first clamping opening; the end of the first linkage arm 4 is provided with multiple groups of second clamping protrusions 10 corresponding to the first clamping protrusions 9, which are arranged in a row on the other side of the first clamping opening; the end of the second clamping arm 2 is provided with multiple groups of third clamping protrusions, which are arranged in a row on one side of the second clamping opening; the end of the second linkage arm 5 is provided with multiple groups of fourth clamping protrusions corresponding to the third clamping protrusions, which are arranged in a row on the other side of the second clamping opening. In this way, one or more can be pulled out at a time, and when there is a vacancy, it will not affect the use. For example, when pulling out 6 tools at the same time, 5 can also be pulled out, and 1 is vacant, which will not affect the function.

[0035] The first linkage arm 4 is connected to the second clamping arm 2 through the second connection column 7 to achieve linkage, that is, to achieve force transmission, to ensure that when the second clamping arm 2 is opened outward, the first linkage arm 4 can also be away from the first clamping arm 1; when the second clamping arm 2 is clamped inward, the first linkage arm 4 can also be close to the first clamping arm 1. The second linkage arm 5 is connected to the first clamping arm 1 through the first connection column 6 to achieve linkage, that is, to achieve force transmission, to ensure that when the first clamping arm 1 is opened outward, the second linkage arm 5 can also be away from the second clamping arm 2; when the first clamping arm 1 is clamped inward, the second linkage arm 5 can also be close to the second clamping arm 2. The embodiment of the present invention achieves simultaneous opening and clamping of multiple clamping ports through force transmission.

[0036] For details, see Figure 1 , Figure 2 , the first connecting column 6 and the second connecting column 7 are both located in the first movable gap, the first linkage arm 4 is provided with a slot or hole, and the second connecting column 7 passes through the slot or hole of the first linkage arm 4 to connect the second linkage arm 5 and the first clamping arm 1; the second linkage arm 5 is provided with a slot or hole, and the first connecting column 6 passes through the slot or hole of the second linkage arm 5 to connect the first linkage arm 4 and the second clamping arm 2. Among them, the staggered arrangement of the force-transmitting connecting columns is more conducive to the uniform transmission of force. The slot or hole should be larger than the cross-sectional size of the connecting column to ensure that the movement of the connecting column is not restricted during the clamping or opening process. The above structure can be manufactured by 3D printing molding technology, and the material used is resin.

[0037] In some embodiments, see Figure 2 The first elastic connection part 3 includes a first arc segment 11, a second arc segment 12 and a third arc segment 13; wherein the first arc segment 11 is connected between the first clamping arm 1 and the first linkage arm 4 to form a U-shaped structure; the second arc segment 12 is connected between the first linkage arm 4 and the second linkage arm 5 to form a U-shaped structure; the third arc segment 13 is connected between the second linkage arm 5 and the second clamping arm 2 to form a U-shaped structure. The first elastic connection part 3 mainly applies a clamping force to the first clamping arm 1 and the second clamping arm 2. The first elastic connection part 3 includes a first arc segment 11, a second arc segment 12 and a third arc segment 13, which can better ensure that when the first elastic connection part 3 is elastically deformed, the positions of the first linkage arm 4 and the second linkage arm 5 in the first movable gap can be better ensured, so that the first clamping opening and the second clamping opening can be opened or clamped synchronously.

[0038] In some embodiments, see Figure 1 , Figure 4The first clamping arm 1 extends away from the first clamping opening to form a first control arm 14; the second clamping arm 2 extends away from the second clamping opening to form a second control arm 15. The clamping arm and the control arm form a rotation fulcrum at the first elastic connection part 3. When in use, the first clamping opening and the second clamping opening can be opened by pressing the control arm.

[0039] Further, in some embodiments, see Figure 1 , the first control arm 14 extends away from the first clamping opening to form a third clamping arm 16; the second control arm 15 extends away from the second clamping opening to form a fourth clamping arm 17; the third clamping arm 16 and the fourth clamping arm 17 are connected by a second elastic connecting portion 18, and a second movable gap is formed between the third clamping arm 16 and the fourth clamping arm 17 for clamping the fuse 8. Both ends of the extraction tool in this embodiment can be used, and can be freely selected according to the operator's strength and actual conditions. After the tool is damaged, the other end can be used to continue working, leaving time for making a new tool.

[0040] The outer surfaces of the first clamping arm, the second clamping arm, the third clamping arm 16 and the fourth clamping arm 17 all have anti-slip corrugations to ensure that no slipping occurs between the fingers and the tool during the process of pulling out the fuse.

[0041] For further information, see Figure 1 In order to ensure that the clamping port can exert a more reliable clamping effect on the fuse, a fifth clamping protrusion 19 for clamping the fuse is provided at one end of the third clamping arm 16 away from the second elastic connection portion 18, and the fifth clamping protrusion 19 faces the fourth clamping arm 17. A sixth clamping protrusion 20 for clamping the fuse is provided at one end of the fourth clamping arm 17 away from the second elastic connection portion 18, and the sixth clamping protrusion 20 faces the third clamping arm 16. The third clamping arm 16 and the fourth clamping arm 17 cooperate to clamp one or a row of fuses 8.

[0042] In some embodiments, see Figure 5The second elastic connecting part 18 is provided with a third linkage arm 21 and a fourth linkage arm 22 extending into the second active gap, and a gap is left between the third linkage arm 21 and the fourth linkage arm 22. The third linkage arm 21 cooperates with the third clamping arm 16 to form a third clamping opening that can be opened and closed. The end of the third linkage arm 21 away from the second elastic connecting part 18 is provided with a seventh clamping protrusion for clamping the fuse, and the seventh clamping protrusion faces the third clamping arm 16. The fourth linkage arm 22 cooperates with the fourth clamping arm 17 to form a fourth clamping opening that can be opened and closed. The end of the fourth linkage arm 22 away from the second elastic connecting part 18 is provided with an eighth clamping protrusion for clamping the fuse, and the eighth clamping protrusion faces the fourth clamping arm 17. The third linkage arm 21 is connected to the fourth clamping arm 17 through the third connecting column to realize linkage during the opening and closing process. The fourth linkage arm 22 is connected to the third clamping arm 16 through the fourth connecting column to realize linkage during the opening and closing process. Two clamping openings, namely the third clamping opening and the fourth clamping opening, are defined in the second movable gap by the third clamping arm 16, the third linkage arm 21, the fourth linkage arm 22 and the fourth clamping arm 17, so that two rows of fuses can be pulled out simultaneously, which is more efficient.

[0043] Each clamping opening is provided with one or more pairs of clamping projections, for example Figure 5 In some embodiments shown, the end of the third clamping arm 16 is provided with multiple groups of fifth clamping protrusions 19, the end of the first linkage arm 4 is provided with multiple groups of seventh clamping protrusions corresponding to the fifth clamping protrusions 19; the end of the fourth clamping arm 17 is provided with multiple groups of sixth clamping protrusions 20, and the end of the fourth linkage arm 22 is provided with multiple groups of eighth clamping protrusions corresponding to the sixth clamping protrusions 20. In this way, one or more fuses can be pulled out at a time, which is more efficient.
