DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0018] Embodiment 1: See also Figure 1 , Figure 2 This embodiment discloses a locking mechanism for a battery cartridge, comprising a housing (in this embodiment, the locking mechanism is applied to a sight, and the housing is the body 1 of the sight), a battery cover 15, an anti-loosening handle 21, an anti-loosening elastic mechanism, an anti-loosening ball, a battery cover hook 26, and a hook elastic mechanism; One end of the battery cover 15 is rotatably connected to the housing, and the other end is provided with a battery cover slot; The anti-loosening handle 21 is slidably connected to the housing, and its end is inserted into / exited between the housing and the battery cover hook 26 as it slides. A anti-loosening handle notch is provided on the side facing the housing, and an anti-loosening elastic mechanism and an anti-loosening ball are provided in the anti-loosening handle notch. The housing is provided with an anti-loosening ball notch for clamping the anti-loosening ball. One end of the battery cover hook 26 and the shell are both provided with an anti-loose elastic mechanism slot for accommodating the anti-loose elastic mechanism, the other end of the battery cover hook 26 is detachably connected to the battery cover slot, and the middle part of the battery cover hook 26 is rotatably connected to the shell.

[0019] Furthermore, the battery cover 15 is rotatably connected to the housing via the battery cover pin 16 ; the battery cover hook 26 is rotatably connected to the housing via the battery cover hook pin 25 .

[0020] Furthermore, there are two anti-loosening ball slots, and the shape of the anti-loosening ball slot is triangular; the two positions of the anti-loosening ball slot correspond to the locking position and unlocking position of the anti-loosening handle 21 respectively. When the anti-loosening handle 21 moves to the anti-loosening ball slot, the anti-loosening ball in the anti-loosening handle 21 moves into the anti-loosening ball slot under the push of the anti-loosening elastic mechanism, thereby achieving a certain degree of limitation on the anti-loosening handle 21. At this time, a certain force is required to push the anti-loosening handle 21.

[0021] Furthermore, the outer sides of the anti-loosening handle 21 and the battery cover hook 26 are provided with anti-slip grooves to help the user operate the locking mechanism; in a preferred embodiment of the present invention, the anti-slip grooves are composed of raised trapezoidal bosses and V-shaped spacing grooves between the trapezoidal bosses.

[0022] Furthermore, the anti-loosening elastic mechanism and the hook elastic mechanism are both springs (ie, the anti-loosening spring 23 and the hook spring 24 shown in the figure), and the anti-loosening ball is a steel ball 22 .

[0023] Embodiment 2: See also Figure 2 , Figure 3 This embodiment discloses a battery cartridge, including the locking mechanism described in the first embodiment, as well as a battery compartment 8, an upper electrode assembly, and a lower electrode assembly; the battery compartment 8 is arranged in the shell, and the upper electrode assembly and the lower electrode assembly are respectively fixed to the inner side of the battery cover 15 and the bottom of the battery compartment 8 (the lower electrode assembly is fixed by the motor pressure ring 2, and the upper electrode assembly is fixed by the electrode pressure plate screw 10).

[0024] Further, the lower electrode assembly includes a negative electrode guide sleeve 5, a positive electrode guide sleeve 6 (the negative electrode guide sleeve 5 and the positive electrode guide sleeve 6 are both provided with an annular groove for fixing the lower electrode 4, and the annular groove is provided with a notch for leading out the wire of the lower electrode 4), and a lower electrode 4 embedded in the negative electrode guide sleeve 5 and the positive electrode guide sleeve 6, the lower electrode 4 located in the positive electrode guide sleeve 6 is recessed in the inner end surface of the positive electrode guide sleeve 6, and the lower electrode 4 located in the negative electrode guide sleeve 5 protrudes from the inner end surface of the negative electrode guide sleeve 5 (in this embodiment, this is achieved by setting the groove depth of the positive electrode guide sleeve 6 to be deeper and the groove depth of the negative electrode guide sleeve 5 to be shallower); The upper electrode assembly includes an electrode pressing plate 12 and an electrode 11; the electrode pressing plate 12 includes a positive electrode portion corresponding to the negative electrode guide sleeve 5 and a negative electrode portion corresponding to the positive electrode guide sleeve 6, and the electrode 11 is respectively embedded in the positive electrode portion and the negative electrode portion, the electrode 11 located in the positive electrode portion is recessed in the inner end surface of the positive electrode portion, and the electrode 11 located in the negative electrode portion is protruded from the inner end surface of the negative electrode portion (in this embodiment, this is achieved by setting the groove depth of the positive electrode portion to be deeper and the groove depth of the negative electrode portion to be shallower); The principle of the lower electrode assembly to realize the battery reverse connection protection function is as follows: when the battery 9 is installed and the negative electrode contacts the positive electrode guide sleeve, since the conductive surface of the negative electrode of the battery 9 is a plane, the negative electrode of the battery 9 can only contact the inner end surface of the positive electrode guide sleeve 6, but cannot contact the lower electrode in the positive electrode guide sleeve 6, and thus cannot supply power; and when the positive electrode of the battery 9 contacts the positive electrode guide sleeve 6, since there is a protrusion on the conductive surface of the positive electrode of the battery 9, the positive electrode of the battery 9 can pass through the inner end surface of the positive electrode guide sleeve 6 and contact the lower electrode 4 in the positive electrode guide sleeve 6, and then supply power normally. The principle of the reverse connection protection function of the upper electrode assembly is the same and will not be repeated here. The battery 9 can only supply power when the user inserts the battery 9 in the specified direction, and then the battery reverse connection protection function is realized through the setting of the mechanical structure, reducing the corresponding cost of the hardware circuit.

[0025] Furthermore, the upper electrode assembly includes a battery cover sealing gasket 14 and an electrode plate 13. The electrode 11 is fixed to the electrode plate 13 (by soldering). The lower electrode 4 is electrically connected to the electrode plate 13 by a wire. The electrode plate 13 provides electrical energy to the battery 9 (a through hole for leading out the corresponding wire is provided on the battery compartment 8). The battery cover sealing gasket 14 is provided between the electrode plate 13 and the battery cover 15 to ensure the sealing performance.

[0026] Furthermore, the lower electrode assembly includes an electrode holder 3 (an arc-shaped protrusion for limiting itself is provided on the side of the electrode holder 3) and an electrode spring 7 arranged on the outside of the positive electrode guide sleeve 6 and the negative electrode guide sleeve 5; the electrode spring 7 is sleeved in the middle of the electrode holder 3, and its two ends are respectively in contact with the lower electrode 4 and the electrode holder 3 (one end of the electrode spring 7 is fixed to the lower electrode 4 by soldering); the set electrode spring 7 can effectively reduce the impact on the battery 9 in the battery compartment 8 to avoid power failure.

[0027] Embodiment three: See also Figure 2 , Figure 4 This embodiment provides a sighting scope, provided with a battery cartridge as described in the second embodiment. It should be understood that: Figure 2 , Figure 4 Only a portion of the scope is shown.

[0028] Furthermore, a control panel for inputting control commands of the sight is arranged on the battery tube.

[0029] Furthermore, the control surface includes a button cover 20, a button panel 17, and a button pad 19. The button panel 17 is fixed to the side of the battery compartment 8 by a button panel screw 18. A boss for fixing the button panel is provided on the side of the battery compartment 8 (the battery compartment 8 is also provided with a through hole for leading out the control signal line of the button panel 17). The button pad 19 and the button cover 20 are sequentially arranged on the button panel 17, and the scope body 1 is provided with a window for exposing the control panel. This embodiment simplifies the assembly difficulty of the sight by integrating the button panel into the battery compartment 8, thereby ensuring the structural stability of the sight.
