DETAILED DESCRIPTION
[0035] 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, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0036] Please refer to Figures 1-8 The embodiment provides a switch structure, which comprises a shell 1, and a bottom plate 6 is installed at the opening of the shell 1, as shown in Figure 1 As shown in the figure, the bottom plate 6 and the shell 1 are fixedly connected together through rivets 3, and the rivets can ensure the stability of the connection between the two and are not prone to loosening.
[0037] A mounting groove is formed on one side of the base plate 6 outside the outer casing 1. A conductive base 8 is installed in the mounting groove. The conductive base 8 is made of conductive metal, preferably copper or aluminum, and has good conductivity. A cylindrical groove is formed on the conductive base 8 for connecting to the negative (or positive) terminal of the battery / electrical battery. A clamping bolt 5 is installed on one side of the conductive base 8. One end of the clamping bolt 5 extends to the outside through the side wall of the base plate 6 and the outer casing 1, while the other end is located inside the conductive base 8. A clamping plate 7 is rotatably installed on the end of the clamping bolt 5 inside the conductive base 8. The clamping plate 7 is made of conductive metal, preferably copper, and has an arc-shaped structure. By rotating the clamping bolt 5, the position of the clamping plate 7 in the conductive base 8 can be adjusted by the action of the thread.
[0038] After inserting the negative terminal of the battery into the conductive base 8, the clamping bolt 5 can be rotated to make the clamping plate 7 move inward, which allows the terminal and the conductive base 8 to come closer to each other and generate a squeezing force, thus achieving the connection between the conductive base 8 and the terminal. At the same time, the outer casing 1 and the base plate 6 are installed on the battery.
[0039] In this embodiment, the top of the conductive base 8 is provided with a threaded hole, and a bolt is installed in the threaded hole to connect it to the base plate 6.
[0040] A second conductive sheet 9 is fixedly installed on the side of the base plate 6 opposite to the conductive base 8, such as... Figures 1-5 As shown, the second conductive sheet 9 is located inside the outer casing 1. The second conductive sheet 9 is connected to the base plate 6 by bolts made of conductive metal, such as copper. The bolts penetrate the side wall of the base plate 6 and connect to the conductive base 8. These bolts mount the second conductive sheet 9 to the base plate 6 and also fix the conductive base 8, thus connecting the conductive base 8 to the base plate 6. Furthermore, they connect the second conductive sheet 9 and the conductive base 8, establishing the electrical connection between them.
[0041] The inside of the outer casing 1 is also equipped with a first conductive sheet 10, such as Figures 2-4 As shown, the first conductive sheet 10 is located above the second conductive sheet 9. A plurality of protrusions are fixedly mounted on one side of the base plate 6 inside the housing 1. The first conductive sheet 10 is mounted between the plurality of protrusions and can slide up and down between the protrusions.
[0042] Conductive bolts 11 are also fixedly installed on the base plate 6, such as Figure 5 As shown, the upper end face of the conductive bolt 11 is flush with the upper end face of the second conductive piece 9, and the maximum distance between the two bolts is less than the length of the first conductive piece 10.
[0043] In this embodiment, the upper end of the outer casing 1 is also provided with a mounting port, and an adjustment structure is installed in the mounting port, such as...Figures 3-5 As shown, the adjustment structure includes:
[0044] Handle 2, which is located on the outside of the mounting port;
[0045] The sliding column 14 is fixedly connected to the handle 2 at one end. Here, both the sliding column 14 and the handle 2 have pin holes on their outer sides. A pin is inserted into the pin hole and the sliding column 14 and the handle 2 are fixedly connected together by the pin. The two can also be fixed together by bolts. There are no restrictions on the specific method, as long as the two can be fixed together.
[0046] The main body of the sliding post 14 is located in the mounting opening. The sliding post 14 can move up and down in the mounting opening and can also rotate in the mounting opening. One end of the sliding post 14 located inside the outer casing 1 is rotatably connected to the first conductive sheet 10. The sliding post 14 is used to move the first conductive sheet 10 closer to or away from the second conductive sheet 9 and the conductive bolt 11.
[0047] like Figures 3-5 As shown, a support column 13 is fixedly installed at the lower middle part of the sliding column 14. A ramp groove is provided on the side wall of the mounting opening. Smooth sections are provided at the top and bottom of the ramp groove. When the support column 13 rotates to the smooth section, it can remain stable in the smooth section and will not slip. The support column 13 is located in the ramp groove and is installed in close contact with the ramp groove. When the sliding column 14 rotates, the support column 13 can move in close contact with the ramp groove. When the support column 13 is at the top of the ramp groove, the first conductive piece 10 is separated from the second conductive piece 9 and the conductive bolt 11 at the same time, and the circuit is broken. When the support column 13 is at the bottom of the ramp groove, the bottom surface of the first conductive piece 10 is in contact with the second conductive piece 9 and the conductive bolt 11 respectively, and the circuit is connected.
[0048] In this embodiment, a return spring 15 is installed between the handle 2 and the outer shell 1. The return spring 15 is located on the outer side of the upper part of the sliding column 14 and is coaxially arranged with the sliding column 14. One end of the return spring 15 contacts the outer shell 1, and the other end contacts the handle 2. The return spring 15 provides an upward elastic force to the handle 2. When the handle 2 is rotated, the sliding column 14 rotates together with the support column 13. When the support column 13 moves downward along the ramp groove, the return spring 15 is compressed. When the support column 13 moves to the smooth end of the bottom of the ramp groove, the sliding column 14, along with the first conductive plate 10, comes into contact with the second conductive plate 9 to connect the circuit.
[0049] When the support column 13 moves upward along the slope groove, the reset spring 15 provides an outward elastic force to the handle 2, so that the support column 13 moves upward along the slope groove to the top of the slope groove, the handle 2, the sliding column 14 and the support column 13 are reset, the sliding column 14 moves upward with the first conductive sheet 10, and the first conductive sheet 10 is reset and separated from the second conductive sheet 9 and the conductive bolt 11. When the first conductive sheet 10 is separated from the second conductive sheet 9 and the conductive bolt 11, the circuit has two open states, which is safer to use. When the support column 13 is located in the smooth section of the slope groove, due to the elastic force of the reset spring 15, there is a pressing force between the support column 13 and the smooth section, and the support column 13 will not be easily displaced or moved without external force, so that the support column 13 is more stable.
[0050] Since the first conductive sheet 10 is rotationally connected with the sliding column 14, the first conductive sheet 10 cannot move in the axial direction of the sliding column 14, and when the first conductive sheet 10 contacts the second conductive sheet 9, the first conductive sheet 10 will be in poor contact (i.e. virtual connection) when it shakes or vibrates. In a further embodiment, a mounting hole matching the bottom of the sliding column 14 is formed in the first conductive sheet 10, and the end of the sliding column 14 inserted into the mounting hole can slide in the axial direction in the mounting hole.
[0051] The sliding column 14 has a limiting ring fixedly installed at one end inside the housing 1, and the limiting ring is located below the first conductive sheet 10. The limiting ring limits the first conductive sheet 10 from falling off the sliding column 14. The sliding column 14 also has a support ring fixedly installed at a middle lower position, and the support ring is located above the first conductive sheet 10 and below the support column 13, i.e. the support ring is located between the support column and the first conductive sheet 10, as shown in Figure 3 and Figure 5 The support ring and the first conductive sheet 10 are provided with a support spring 12, one end of the support spring 12 contacts the support ring, and the other end contacts the first conductive sheet 10. The support spring 12 provides a downward elastic force to the first conductive sheet 10, and when the first conductive sheet 10 is in a separated state from the second conductive sheet 9, the support spring 12 keeps the first conductive sheet 10 at the bottom of the sliding column 14 and in close contact with the limiting ring.
[0052] When the sliding column 14 moves downward with the first conductive sheet 10, the first conductive sheet 10 is prevented from moving downward by the second conductive sheet 9 and the conductive bolt 11, and the sliding column 14 continues to move downward, the supporting spring 12 is compressed, and greater elastic force is provided to the first conductive sheet 10, so that the first conductive sheet 10 is tightly attached to the second conductive sheet 9 and the conductive bolt 11, avoiding the situation that the first conductive sheet 10 is not connected to the second conductive sheet 9 and the conductive bolt 11 due to shaking.
[0053] In the embodiment, one end of the first conductive sheet 10 can also be fixedly connected with the conductive bolt 11, the conductive bolt 11 is provided with the conductive wire 4 through a nut, and the two ends of the conductive wire 4 are fixedly connected with metal rings. The metal ring at one end of the conductive wire 4 is sleeved on the conductive bolt 11, and the nut on the conductive bolt 11 is tightened, so that the installation of the conductive wire 4 is realized, and the conductive bolt 11 has the function of conducting electricity and can transmit electric energy to the conductive wire. As shown in Figure 6 and Figure 7 As shown in the drawings, the bottom plate 6 is provided with a notch for installing the conductive bolt 11, the conductive bolt 11 and the bolt on the upper portion thereof can move in the notch, and when the first conductive sheet 10 approaches or moves away from the second conductive sheet 9, the conductive bolt 11 can move synchronously with the first conductive sheet 10 in the notch. It should be noted that the conductive wire 4 has a certain allowance in the present scheme, so that the conductive wire 4 can move synchronously with the conductive bolt 11.
[0054] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, and the skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed, and the scope of protection of the utility model is defined by the appended claims and their equivalents.
