[0042] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0043] Please refer to Figures 1 to 8 , Figure 1 A schematic diagram of a battery module and a battery loading slot provided by an embodiment of the present invention being locked and fixed, Figure 2 A schematic diagram of a sliding lock provided by an embodiment of the present invention being pushed away from the upper groove, Figure 3 An exploded diagram of the structure provided by an embodiment of the present invention, Figure 4 A schematic diagram of a top view structure provided by an embodiment of the present invention, Figure 5 A cross-sectional view along the AA direction provided by an embodiment of the present invention, Figure 6 A cross-sectional view along the BB direction provided by an embodiment of the present invention, Figure 7 A schematic diagram of a sliding lock structure provided by an embodiment of the present invention, Figure 8 A schematic structural diagram of a battery positioning plate provided by an embodiment of the present invention.

[0044] The battery locking device provided in the embodiment of the present invention is specifically applied to a barcode scanner, so that the battery of the barcode scanner can be easily replaced, and the battery module 1 is not easy to loosen, thereby avoiding leakage, poor contact, etc. Specifically, the battery locking device includes a battery module 1, a handle 2 and a sliding lock 3, and the sliding lock 3 limits the rotation of the battery module 1 relative to the handle 2, so that the battery module 1 is more stably locked and fixed on the barcode scanner.

[0045] according to Figures 1 to 3 As shown, Figure 1The figure is a schematic diagram of the battery module 1 being locked and fixed in the battery filling slot 21. When the battery module 1 needs to be fixed on the barcode scanner, the battery locking device fits a sliding lock 3 in the lock slot formed by the docking between the battery module 1 and the handle 2. The sliding lock 3 fits the inner wall of the upper groove 12 and the lower groove 22 at the same time, thereby limiting the rotation of the battery module 1 relative to the handle 2, thereby achieving the locking and fixing function. When the battery module 1 needs to be removed from the handle 2, as shown in FIG. Figure 2 As shown, the sliding lock 3 is pushed away from the upper groove 12, and the sliding lock 3 is now only accommodated in the lower groove 22 of the handle 2, so that the battery module 1 can rotate relative to the handle 2, and the battery module 1 can be removed from the handle 2 after rotating 90 degrees counterclockwise.

[0046] according to Figure 3 and Figure 4 As shown, the battery module 1 can be fixedly locked with the battery filling slot 21 of the handle 2 in a detachable manner, a top cover 11 is provided at one end of the battery module 1, an upper groove 12 is provided on one side of the top cover 11, a lower groove 22 is provided on the edge of the slot of the battery filling slot 21, and the upper groove 12 and the lower groove 22 can be connected and surrounded to form a lock groove; the battery locking device also includes a sliding lock 3, which can slide in the upper groove 12 and the lower groove 22 to limit the rotation of the battery module 1 relative to the handle 2. Specifically, the upper groove 12 is provided on the side wall of the top cover 11, and the upper groove 12 is a groove with an opening at one end, and the opening portion of the upper groove 12 faces the handle 2, and the lower groove 22 is a groove with an opening at one end, and the opening portion of the lower groove 22 faces the top cover 11. When the battery module 1 is locked and fixed with the battery loading slot 21, the openings of the upper groove 12 and the lower groove 22 are relatively butted against each other, and the upper groove 12 and the lower groove 22 are butted against each other to form a locking groove, in which the sliding lock 3 can slide; Figure 1 As shown, when the battery module 1 is locked and fixed with the battery loading slot 21, one end of the sliding lock buckle 3 abuts against the bottom of the upper groove 12, the upper part of the sliding lock buckle 3 abuts against the upper groove 12, and the lower part of the sliding lock buckle 3 abuts against the lower groove 22; when the battery module 1 tends to rotate relative to the handle 2, the upper groove 12 also tends to rotate relative to the lower groove 22. At this time, because the sliding lock buckle 3 abuts against the groove walls of the upper groove 12 and the lower groove 22 at the same time, the upper groove 12 and the lower groove 22 squeeze the sliding lock buckle 3 in opposite directions, causing the sliding lock buckle 3 to deform to form a stress to resist the squeezing force of the upper groove 12 and the lower groove 22, offsetting the movement tendency of the upper groove 12 relative to the lower groove 22, thereby offsetting the rotation tendency of the battery module 1 relative to the handle 2.

[0047] For further information, please refer to Figures 3 to 6The side of the sliding lock 3 facing the bottom of the lock groove is connected with a guide block 31, and the elastic member 5 and the guide block 31 are accommodated in the guide groove 23. The guide groove 23 serves to limit the elastic member 5 and the guide block 31 to prevent the elastic member 5 from being misaligned. The guide groove 23 is opened at the bottom of the axial limit groove 211 of the handle 2, and the elastic member 5 accommodated therein connects the handle 2 and the guide block 31 of the sliding lock 3 in a pressure manner. The elastic member 5 is always in a compressed state, providing elastic forces in opposite directions to the guide block 31 and the handle 2 respectively. The handle 2 resists the elastic force through its own deformation and the user's gripping force, and the sliding lock 3 is pushed toward the upper groove 12 due to the elastic force, so that the sliding lock 3 always contacts the bottom of the upper groove 12, and at the same time contacts the groove wall of the upper groove 12 and the groove wall of the lower groove 22, so that the battery module 1 cannot rotate relative to the handle 2, to avoid the situation that the user forgets to slide the sliding lock 3 upwards after the battery module 1 is locked and fixed with the battery filling groove 21, thereby causing the battery module 1 to loosen, so that the battery locking device has an automatic reset function to ensure that the battery module 1 is locked on the handle 2. If a force is applied to the sliding lock 3 toward the lower groove 22, the force is sufficient to overcome the elastic force of the elastic member 5, so that the elastic member 5 is in the maximum compression state and the minimum length, that is, the sliding lock 3 is pushed away from the upper groove 12, the battery module 1 can rotate relative to the handle 2, the docking between the upper groove 12 and the lower groove 22 is released, the sliding lock 3 is compressed by the top cover 11, and the elastic member 5 continues to maintain the maximum compression state and the minimum length until the battery module 11 is removed from the handle 2, and the sliding lock 3 continues to move outward under the action of the elastic member 5, and is then blocked by the battery positioning plate 4 at the end position.

[0048] On the basis of the above embodiment, the elastic member 5 is a spring, and a guide block 31 is provided on the side of the sliding lock 3 facing the battery module 1. The spring is always compressed by the guide block 31, so the spring always provides an elastic reaction force to the guide block 31, so that the sliding lock 3 always slides toward the upper groove 12, which plays a role in ensuring that the sliding lock 3 can limit the rotation of the battery module 1 relative to the handle 2; the guide block 31 is a cylinder with a diameter smaller than the inner diameter of the spring, which ensures that the spring can be sleeved on the guide block 31, so that the spring can be compressed or stretched along the sliding direction of the sliding lock 3 to prevent the spring from deflecting; a spring extrusion block 34 is arranged around the guide block 31 to ensure that the elastic force of the spring can accurately act on the guide block 31 to prevent the elastic force from deflecting. The use of a spring in the elastic member 5 has the advantages of simple structure and low cost.

[0049] It should be supplemented that the elastic member 5 can be in other forms. For example, the elastic member 5 is a micro cylinder, one end of which is fixed to the bottom surface of the guide groove 23, and the other end is fixedly connected to the guide block 31 through a thread. Of course, the guide block 31 needs to have a corresponding threaded hole. The elastic member 5 is a micro cylinder, which has the advantages of stable structure, stable elastic force and smooth transition.

[0050] Furthermore, if Figure 3 and Figure 7 As shown, the sliding lock 3 is connected to the guide block 31 through the first slider 321. In order to ensure the normal sliding of the sliding lock 3 in the upper groove 12 and the lower groove 22, the bottom of the upper groove 12 is provided with a first upper avoidance groove 131, and the first upper avoidance groove 131 is open on the side facing the handle 2. The bottom of the lower groove 22 is provided with a first lower avoidance groove 241, and the second lower avoidance groove 242 is open on the side facing the battery module 1. When the battery module 1 and the battery filling groove 21 are locked and fixed, the opening parts of the first upper avoidance groove 131 and the first lower avoidance groove 241 are docked, so that the first upper avoidance groove 131 and the first lower avoidance groove 241 are docked and enclosed to form a first through groove, and the first slider 321 is slidably connected with the first slide groove. Through the arrangement of the first slider 321 and the first slide groove, the sliding lock 3 of the battery locking device has the characteristics of stable structure, high parallelism and smooth sliding when sliding in the lock groove.

[0051] Furthermore, one end of the battery part 14 is fixedly connected to the top cover 11, and the battery part mounting groove 212 is communicated with the axial limit groove 211, wherein the battery part mounting groove 212 is used to accommodate the battery part 14, and the axial limit groove 211 is used to fix the battery positioning plate 4; the battery positioning plate 4 is provided with three hollow cylinders for positioning on the side facing the axial limit groove 211, and the axial limit groove 211 is provided with positioning columns that can be inserted into the hollow cylinders, and the function of positioning the battery positioning plate 4 in the handle 2 is realized by sleeved the three hollow cylinders on the positioning columns; the hollow cylinder and the positioning column are correspondingly provided with center holes, and the hollow cylinder and the positioning column can be fixedly connected by fasteners, thereby realizing the function of fixing the battery positioning plate 4 to the handle 2.

[0052] To limit the axial movement of the battery module 1 after it is locked and fixed with the battery filling slot 21, please refer to Figure 8 , a guide portion 43 is provided at the bottom of the battery positioning plate 4, and a battery buckle fixing groove 44 is provided on one side of the guide portion 43 away from the groove wall of the axial limiting groove 211. Specifically, when the battery module 1 is locked and fixed in the battery filling groove 21, the battery module 1 is rotated by a certain angle. On the one hand, the upper groove 12 and the lower groove 22 can be connected and surrounded to form a lock buckle groove, so that the sliding lock buckle 3 can slide axially toward the upper groove 12 to limit the rotation of the battery module 1; on the other hand, during the rotation of the battery module 1, the battery buckle 15 enters the first battery buckle fixing groove 441 by abutting against the bottom hole end face of the through hole 41, and slides in the first battery buckle fixing groove 441. When the upper groove 12 and the lower groove 22 are connected and surrounded to form a lock buckle groove, the first battery buckle fixing groove 441 limits the axial movement of the battery buckle 15, thereby locking the battery module 1.

[0053] A through hole 41 for avoiding the battery part 14 is provided in the center of the battery positioning plate 4; a battery buckle 15 is convexly provided on the outer wall of the battery part 14; a positioning groove 42 for avoiding the battery buckle 15 is provided on the hole wall of the through hole 41; the battery part 14 is cylindrical. When installing the battery module 1, first align the battery part 14 and the battery buckle 15 with the positioning groove 42, and then put the battery module 1 into the handle 2 through the battery positioning plate 4, so that the top cover 11 is placed on the groove edge of the battery filling groove 21 and the battery positioning plate 4. At this time, the battery buckle 15 has been aligned with the first battery buckle fixing groove 441. Next, the battery module 1 only needs to be rotated 90 degrees to screw the battery buckle 15 into the first battery buckle fixing groove 441, thereby limiting the axial movement of the battery module 1 relative to the handle 2 and realizing the function of locking the battery. When the battery module 1 is disassembled, it is only necessary to press the sliding lock 3 downward to rotate the battery module 1 in the opposite direction so that the battery part 14 and the battery buckle 15 can be taken out through the positioning groove 42; it should be supplemented that the battery buckle fixing groove 44 also includes a second battery buckle fixing groove, and the second battery buckle fixing groove and the first battery buckle fixing groove 441 are respectively arranged at both ends of the positioning groove 42, and the second battery buckle fixing groove is arranged opposite to the first battery buckle fixing groove 441, and the second battery buckle fixing groove plays the same role as the first battery buckle fixing groove 441, and the details are not elaborated again. The setting of the second battery buckle fixing groove makes the battery locking device more stable in the axial restriction of the battery module 1.

[0054] Furthermore, if Figure 3 and Figure 7 As shown, a limit block 33 for limiting the sliding lock 3 from sliding off the lower groove 22 is connected to the side of the sliding lock 3 facing the bottom of the lock groove; a second slider 322 is connected between the sliding lock 3 and the limit block 33; a second upper avoidance groove 132 is also provided at the bottom of the upper groove 12, and the second upper avoidance groove 132 is open toward the end of the handle 2; a second lower avoidance groove 242 is also provided at the bottom of the lower groove 22, and the second lower avoidance groove 242 is open toward the end of the battery module 1; the battery module 1 is locked and fixed with the battery loading groove 21 Timingly, the opening parts of the second upper avoidance groove 132 and the second lower avoidance groove 242 are connected, the second upper avoidance groove 132 and the second lower avoidance groove 242 are surrounded to form a second through groove, and the second slider 322 is slidably connected to the second through groove; through the setting of the second slider 322 and the second slide groove, the sliding lock 3 of the battery locking device has the characteristics of structural stability, high parallelism and smooth sliding when sliding in the lock groove, and the second slider 322 and the first slider 321 slide at the same time to limit the rotation of the sliding lock 3 and prevent the sliding lock 3 from shifting.

[0055] The limit block 33 is provided with an anti-detachment block 331 protruding in the direction away from the sliding lock 3; the anti-detachment block 331 is arranged at one end of the limit block away from the second slider 322; when the battery module 1 is rotated out of the battery loading slot 21, the anti-detachment block 322 abuts against the bottom of the battery positioning plate 4 to prevent the sliding lock 3 from detaching from the handle 2.

[0056] Furthermore, a limit block avoidance groove 214 is also provided at the bottom of the axial limit groove 211. When the sliding lock buckle 3 is pushed away from the upper groove 12, a portion of the limit block 33 is accommodated in the limit block avoidance groove 214 to lengthen the sliding stroke of the sliding lock buckle 3 and avoid the limit block 33 from colliding with the handle 2 and damaging the parts.

[0057] Furthermore, if Figure 3 As shown, further, a pressing groove 35 is provided in the center of the side surface of the sliding lock buckle 3 away from the locking groove, and the pressing groove 35 is for the user to press. The user can directly press the pressing groove 35 to apply a downward pressure to the sliding lock buckle 3, so that the user can easily slide the sliding lock buckle 3 downward. Specifically, the pressing groove 35 is arranged on the side of the sliding lock buckle 3 away from the battery module 1, and the pressing groove 35 extends along the outer contour direction of the surface, and the groove wall of the pressing groove 35 extends along the surface contour of the sliding lock buckle 3, and the groove side width and thickness of the pressing groove 35 are both smaller than the groove side length of the pressing groove 35.

[0058] Furthermore, in order to further ensure the smooth rotation of the battery module 1, a knob guide 25 is provided at the top of the handle 2 on one side of the battery filling slot 21, and a knob guide arc surface 251 for guiding the rotation of the top cover 11 is formed on the side of the knob guide 25 close to the battery filling slot 21; when the battery module 1 is locked and fixed with the battery filling slot 21, the top cover 11 fits with the knob guide arc surface 251. A section of the outer contour of the top cover 11 is set as an arc, and the arc contour of the knob guide arc surface 251 is the same as the arc, and the center of the arc is the same as the center of the battery part 14. When the battery module 1 rotates, the top cover 11 also rotates accordingly. Since the arc and the center of the battery part 14 coincide, the arc section of the top cover 11 draws a circle, and this circle coincides with the knob guide arc surface 251, so that the battery module 1 contacts the handle 2 smoothly.

[0059] Furthermore, a sealing groove 213 is provided at the connection between the bottom of the axial limit groove 211 and the battery mounting groove 212, and a sealing member 6 that can fit tightly with the battery is embedded in the sealing groove 213. The sealing ring 6 is embedded in the sealing groove 213 and is arranged below the battery positioning plate 4. When the battery module 1 passes through the battery positioning plate 4, the battery part 14 is squeezed with the sealing ring 6 to achieve a sealing and waterproof effect.

[0060] In summary, the battery locking device provided in this embodiment is specifically applied to the battery installation structure of the barcode scanner, and can also be applied to various portable devices that require battery removal. The battery locking device is specifically provided with a lower groove 22 and an upper groove 12 on the handle 2 and the battery module 1, respectively. The upper groove 12 and the lower groove 22 are connected to form a locking groove, and the sliding lock 3 is locked on the locking groove to limit the rotation of the battery module 1 relative to the handle 2, thereby achieving the function of completely locking the battery module 1, thereby avoiding the problem of easy shaking and power loss caused by the battery module 1 not being close to the handle 2.
