Detailed Implementation
[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0028] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.
[0029] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.
[0030] Reference Figures 1-4 A screw-in battery case includes: a case body 1, a case cover 2 and an electrode base 3. The case body 1 is provided with a battery placement cavity, and the bottom of the battery placement cavity is provided with a first electrode assembly that is in communication with the battery in the battery placement cavity.
[0031] The lid 2 is provided with an internal thread 21, and the opening of the body 1 is provided with an external thread 11 that is compatible with the internal thread 21;
[0032] The electrode holder 3 is rotatably mounted on the side of the cover 2 near the body 1, and the electrode holder 3 is provided with a second electrode assembly that is in communication with the battery in the battery placement cavity.
[0033] Based on the above structure, during use, the battery is placed in the battery placement cavity, and the cover 2 is fixed to the body 1 by screwing on the cover 2. The electrode seat 3 is rotatably mounted on the cover 2. Therefore, during the screwing and turning of the cover 2, the electrode seat 3 can rotate relative to the cover 2, while the electrode seat 3 does not rotate relative to the body 1, so that the position of the second electrode assembly relative to the battery electrode remains unchanged. This ensures that after the cover 2 is screwed onto the body 1, the second electrode assembly on the electrode seat 3 is in communication with the battery electrode assembly. The screw connection between the cover 2 and the body 1 makes it easy to install and remove the battery and prevents the cover 2 from falling off.
[0034] like Figure 2 and Figure 3As shown, in order to ensure that the position of the second electrode assembly matches the position of the battery electrode, a number of limiting blocks 12 are arranged circumferentially at the opening of the box body 1, and a number of limiting grooves 31 are arranged circumferentially on the electrode seat 3. The number of limiting blocks 12 and the number of limiting grooves 31 correspond one-to-one. Thus, when installing the box cover 2, the limiting blocks 12 are first locked in the limiting grooves 31. At this time, the position of the second electrode assembly corresponds to the position of the battery electrode. When the box cover 2 is rotated, the electrode seat 3 rotates relative to the box cover 2, thereby ensuring that the rotation of the box cover 2 will not change the relative position of the electrode seat 3 and the box body 1 (there will be no relative rotation). After the box cover 2 is screwed on, the second electrode assembly is always in contact with the battery electrode.
[0035] like Figure 3 As shown, the battery placement cavity consists of several battery cavities 13 distributed along the circumference. Each battery cavity 13 has a first electrode assembly at its bottom and several second electrode assemblies. The several second electrode assemblies correspond one-to-one with the several battery cavities 13. In this way, multiple batteries can be installed in the box 1, and the two poles of the battery in each battery cavity 13 are connected to the independent first electrode assembly and second electrode assembly.
[0036] like Figure 4 As shown, the first electrode assembly includes a first elastic element 4 and a wire 5. The first elastic element 4 is disposed at the bottom of the battery cavity 13. One end of the wire 5 is connected to the first elastic element 4, and the other end extends to the outside of the housing 1. Thus, after the battery is placed in the battery cavity 13, one end of the battery contacts the first elastic element 4 (the first elastic element 4 is conductive and can be a spring or a sheet, etc.), and finally leads out of the housing 1 through the wire 5.
[0037] like Figure 4 As shown, the second electrode assembly includes an electrode plate 6 and a contact electrode. The electrode plate 6 is disposed on the electrode base 3 (for insulation, an insulating gasket 32 is disposed on the electrode base 3, the electrode plate 6 is disposed on the insulating gasket 32, and the insulating gasket 32 is fixed to the electrode base 3 by bolts). The electrode plate 6 is disposed on the top of the battery cavity 13. One end of the contact electrode is connected to the electrode plate 6, and the other end extends to the outside of the box body 1 or the box cover 2. The electrode plate 6 includes a first contact plate 61 and a second contact plate 62 connected to the first contact plate 61. The first contact plate 61 is disposed on the top of the battery cavity 13. The contact electrode is disposed on the circumferential side of the box body 1, and the second contact plate 62 is disposed on the top of the contact electrode. Thus, when the box cover 2 is screwed onto the box body 1, the first contact plate 61 is connected to one end of the battery, and the second contact plate 62 is connected to the contact electrode, thereby guiding one electrode of the battery to the outside of the box body 1.
[0038] like Figure 4As shown, to ensure contact between the contact electrode and the second contact plate 62, the contact electrode includes a fixed sleeve 7, a second elastic element 8 (which can be a spring or a spring sheet, etc.), and a top head 9. The fixed sleeve 7 is disposed on the box body 1 (specifically, a mounting seat is provided circumferentially on the outer side of the box body 1, and the fixed sleeve 7 passes through the mounting seat). The opening of the fixed sleeve 7 faces upward, and the top head 9 slides down inside the fixed sleeve 7. The second elastic element 8 is disposed at the bottom of the top head 9, and the bottom of the fixed sleeve 7 extends outside the box body 1. Thus, the second elastic element 8 applies an upward pushing force to the top head 9 (the top head 9 is locked inside the fixed sleeve 7 and will not detach from the fixed sleeve 7). When the box cover 2 is screwed onto the box body 1, the top head 9 is squeezed into the fixed sleeve 7 (the second elastic element 8 is compressed), ensuring that the top head 9 contacts the second contact plate 62.
[0039] A further optimization is that, in this embodiment, the battery cavity 13 is provided with three parts, which can be adjusted adaptively during production according to actual usage requirements.
[0040] In summary, when using the battery, place it in the battery placement cavity and fix the cover 2 to the body 1 by screwing on the cover 2. The cover 2 is threadedly connected to the body 1, which makes it easy to install and remove the battery and prevents the cover 2 from falling off.
[0041] Because each battery compartment in this application is individually equipped with a first electrode assembly and a second electrode assembly, each battery compartment is set up independently, so there is no need to consider the positive and negative polarities when installing the battery. After the battery box is installed in the battery compartment of the device, it is adjusted by the adaptive circuit on the device, which greatly improves the safety and convenience of using the battery box. At the same time, the battery bracket is eliminated, and the battery box can be directly installed in the battery compartment, effectively reducing the weight of the device. It is especially suitable for military equipment, such as observation scopes and aiming scopes, which facilitates blind operation at night.
[0042] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
