Description

Technical Field

[0001] The utility model belongs to the technical field of aiming instruments, and particularly relates to a battery cover which is resistant to disassembly by children. Background Art

[0002] Most laser sights use lithium batteries as power sources. A battery cover is generally used to seal the button lithium battery in the battery compartment. The most common method is to connect the battery cover and the battery compartment through threads. This method is simple to use and easy to assemble and disassemble. However, its defects are also very prominent and obvious. That is, under appropriate rotational force, it is easy to open the battery cover and take out the button battery. This is easy for children who can easily access the sight. It is easy to unscrew the battery cover. Out of curiosity, children will remove the battery with their bare hands. There is an inevitable risk of accidental injury to children during the disassembly process. For this reason, people have developed a battery cover connection structure with an embedded snap-on connection. However, this structure is inevitably opened by children with their bare hands under the premise of appropriate external force, and still cannot avoid accidental injury to children when removing the battery cover with bare hands.

[0005] A threaded connection column with external threads is provided on the inner side surface of the cover body and is located on the inner circle of the circumferential side wall;

[0006] A tool insertion opening is provided on the outer side of the cover body.

[0007] As a further improvement, a recessed clamping ring is provided at each of the axial outer end and the inner end of the circumferential side wall, and a protruding ring that can be clamped into the recessed clamping ring is provided on the fitting surface between the sliding sleeve and the circumferential side wall.

[0008] As a further improvement, the axial outer end and the inner end of the circumferential side wall are each provided with a concave buckle, and the fitting surface of the circumferential side wall of the sliding sleeve is provided with a protrusion that can be snapped into the concave buckle.

[0009] As a further improvement, an inwardly concave buckle or inwardly concave clamping ring is provided on the axial center line of the circumferential side wall, and a clamping block which can be clamped into the inwardly concave buckle or inwardly concave clamping ring is provided on the fitting surface of the sliding sleeve and the circumferential side wall.

[0010] As a further improvement, the tool insertion opening is a slotted opening or a cross opening.

[0011] As a further improvement, a plurality of vertical anti-slip ridges uniformly arranged along the circumferential direction are engraved on the outer circumferential side wall of the sliding sleeve.

[0012] The utility model has the advantages of simple structure, convenient operation and maintenance, and especially good anti-disassembly performance and safety performance. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they should not be construed as limitations on the present invention. The terms "first" and "second" are used for descriptive purposes only and should not be construed to indicate or imply relative importance or to implicitly specify the number of the technical features referred to. Therefore, features defined as “first” or “second” may explicitly or implicitly include one or more of the features; in the description of the present utility model, unless otherwise specified, “plurality” means two or more.

[0026] In order to achieve a secure connection and a battery cover that is not easy to open with bare hands, and to avoid accidental injuries when opening the battery cover with bare hands, this embodiment provides a Figure 1 The child-resistant battery cover shown includes a cover body 1 and a sliding sleeve 3 that is snapped onto the outside of the circumferential side wall 2 of the cover body 1. The sliding sleeve 3 rotates circumferentially relative to the cover body 1 under the action of an external force; a threaded connecting column 4 with an external thread is provided on the inner side surface of the cover body 1 and is located on the inner circle of the circumferential side wall 2; and a tool insertion port 7 is provided on the outer side surface of the cover body 1. The tool insertion port 7 can be the most common flat-edge or cross-edge, and can be used with a screwdriver or a special sheet tool.

[0027] The battery cover provided in this embodiment is mainly assembled and disassembled by the threaded connection column and the battery compartment threaded connection, and the battery cover can be rotated with the help of a screwdriver or a special tool that matches the tool insertion port 7 on the outer surface of the battery cover. It cannot be twisted by hand. When twisting it by hand, hold the sliding sleeve 3, and the sliding sleeve 3 and the battery cover body are connected by Figure 1 、 2 , 3 shown in the recessed collar 5 and the protruding collar 6 or Figure 4 、 5 The recessed buckle 8 and the protrusion 9 shown in the figure cooperate with each other or Figure 6 、7 8 shown in the concave buckle or concave collar 10 and the card block 11 can rotate relative to each other, but can not twist the battery cover, so it can not be unscrewed. Figure 9 The connection between the battery cover and the battery compartment 14 shown prevents children from opening the battery cover with their bare hands, thereby achieving effective protection for children.

[0028] Regarding the arrangement of the recessed collar 5 and the protruding collar 6 that cooperate with each other, Figure 1 、 2 As can be clearly seen from Figures 3 and 4, a recessed clamping ring 5 is provided at the axial outer end and inner end (i.e., viewed in the axial direction) of the circumferential side wall 2, and a protruding ring 6 that can be inserted into the recessed clamping ring 5 is provided on the fitting surface of the sliding sleeve 3 and the circumferential side wall 2. When the sliding sleeve 3 is rotated by an external force, the protruding ring 6 rotates relative to the cover body 1 along the recessed clamping ring 5, and the cover body 1 cannot be twisted, ensuring that when the sliding sleeve 3 is rotated by hand, the cover body 1 is stationary and the battery cover cannot be opened.

[0029] The arrangement of the concave buckle 8 and the protrusion 9 that cooperate with each other, Figure 4 、 5 It can be clearly seen that the axial outer end and inner end of the circumferential side wall 2 are each provided with a concave snap buckle 8, and the fitting surface between the sliding sleeve 3 and the circumferential side wall 2 is provided with a protrusion 9 that can be snapped into the concave snap buckle 8. Similarly, under the action of external force rotation, the sliding sleeve 3 rotates relative to the cover body 1 along the concave snap buckle 8 with the help of the protrusion 9, and the cover body 1 cannot be twisted, ensuring that when the sliding sleeve 3 is rotated barehanded, the cover body 1 is stationary and the battery cover cannot be opened.

[0030] The arrangement of the concave buckle or concave collar 10 and the clamping block 11 that cooperate with each other, such as Figure 6 、 7 As shown in Figures 8 and 8, a concave buckle or a concave clamping ring 10 is provided on the axial center line of the circumferential side wall 2, and a clamping block 11 that can be clamped into the concave buckle or the concave clamping ring 10 is provided on the fitting surface of the sliding sleeve 3 and the circumferential side wall 2. As mentioned above, when the sliding sleeve 3 is rotated by an external force, the clamping block 11 is used to rotate relative to the cover body 1 along the concave buckle or the concave clamping ring 10, and the cover body 1 cannot be twisted, ensuring that when the sliding sleeve 3 is rotated by hand, the cover body 1 is stationary and the battery cover cannot be opened.

[0031] With the help of Figure 9 or Figure 10 As can be seen, the outer circumferential sidewalls of the sliding sleeve 3 provided in the above embodiments are provided with a plurality of vertical anti-slip ridges 12, i.e., ridges parallel to the axis, arranged evenly along the circumference. Other friction surface designs, such as patterns or grids, may also be employed. Finally, it should be noted that the specific material of the sliding sleeve 3 can be plastic, rubber, or metal such as stainless steel to enhance comfort and feel.
