Description

Technical Field

[0001] This utility model relates to the field of battery protection case technology, and in particular to an adjustable snap-on battery protection case. Background Technology

[0002] Batteries are typically placed inside a protective case to prevent damage during use and to ensure stability. However, when there is a limit to the number of batteries or the number of batteries is insufficient to fill the protective case, the empty spaces inside can cause batteries in adjacent slots to become unstable. This instability can lead to batteries tilting, which may prevent them from making full contact with the contacts, resulting in poor battery functionality. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable snap-on battery protective case, which solves the problem of unstable battery placement when the battery is not fully positioned.

[0004] To address the existing technical problems, the technical solution of this utility model is as follows: An adjustable snap-on battery protective case includes a lower housing with openings on one side and the top. The opening end of the lower housing is covered by an L-shaped upper cover. Contact pieces are provided on the opposite surfaces of the upper cover and the lower housing. The inner wall of the lower housing is provided with several partition frames parallel to the lower housing. A rotating rod is inserted into the center of the partition frame. The part of the rotating rod located inside the partition frame is threaded. The rotating rod is threadedly connected to a limiting frame. Limiting rods inserted into the partition frames are slidably connected to both ends of the limiting frame. Horizontally extending paddles are provided on both sides of the limiting frame. A control button is rotatably provided on the side wall of the upper cover. The end of the control button abuts against the rotating rod.

[0005] Furthermore, the upper cover and the lower housing are connected by a pivot shaft located at the opening end of the lower housing, ensuring an effective connection between the upper cover and the lower housing.

[0006] Furthermore, the lower housing is divided into several independent placement cavities by a partition frame. The diameter of each placement cavity is larger than the diameter of the battery, ensuring that the battery can be smoothly placed in the placement cavity and is restrained.

[0007] Furthermore, the number of control buttons on the surface of the upper cover is adapted to the rotating rod. Each control button is divided into an operation part and a control part. The operation part extends to the outside of the upper cover, and the control part extends into the lower housing and abuts against the rotating rod, ensuring that each control button can be adapted to and controlled by a corresponding rotating rod.

[0008] Furthermore, the control part of the control button and the contact surface of the rotating rod are provided with mutually compatible limiting patterns to ensure that the control button can effectively control the rotating rod.

[0009] Furthermore, the shape of the limiting frame is adapted to the cross-section of the partition frame to prevent the limiting frame from being obstructed during movement.

[0010] Furthermore, the levers on both sides of the limiting frame are flexible rubber strips that bend toward the inner wall of the lower housing. Each limiting rod has levers symmetrically arranged at both ends, so that one limiting rod can control the batteries on both sides at the same time.

[0011] Furthermore, the levers within each pair of adjacent limiting frames are staggered to prevent the limiting frames from interfering with each other.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This utility model provides a battery by setting several partition frames inside the lower housing, allowing the battery to be placed in several placement cavities separated by the partition frames. Removing a battery from one placement cavity will not affect the normal use of batteries in other placement cavities. Furthermore, the batteries in each placement cavity are restricted from the empty space by the levers on both sides of the limiting frame, preventing the batteries from tilting to the side of the empty space and avoiding the batteries becoming unusable due to tilting and not being able to make contact with the contacts.

[0014] 2. The lever that contacts and restricts the battery's placement is made of a flexible material. When the lever contacts the battery, it will deform and bend to prevent the lever from pushing the battery excessively, or the battery from being blocked by a large number of batteries on one side and unable to continue moving to the side with a small number of batteries. This ensures that the lever can block the batteries in each placement cavity. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] like Figure 1-4 As shown, an adjustable snap-on battery protective case includes a lower housing 1 with openings on one side and top. An L-shaped upper cover 2 covers the opening end of the lower housing 1. The upper cover 2 and the lower housing 1 are connected by a pivot at the opening end of the lower housing 1 to ensure an effective connection between the upper cover 2 and the lower housing 1. Contact pieces 3 are provided on the opposite surfaces of the upper cover 2 and the lower housing 1. Several partition frames 4 parallel to the lower housing 1 are provided on the inner wall of the lower housing 1. The lower housing 1 is divided into several independent placement cavities by the partition frames 4. The diameter of each placement cavity is larger than the diameter of the battery to ensure that the battery can be placed smoothly in the placement cavity and is restrained.

[0023] A rotating rod 5 is inserted at the center of the partition frame 4. The part of the rotating rod 5 located inside the partition frame 4 is provided with a thread 6. The rotating rod 5 is connected to a limiting frame 7 through the thread 6. The shape of the limiting frame 7 is adapted to the cross section of the partition frame 4 to avoid the limiting frame 7 being obstructed during movement. Limiting rods 8 inserted into the partition frame 4 are slidably connected to both ends of the limiting frame 7. Horizontally extending paddles 9 are provided on both sides of the limiting frame 7. The paddles 9 on both sides of the limiting frame 7 are flexible rubber strips that bend toward the inner wall of the lower housing 1. Paddles 9 are symmetrically provided at both ends of each limiting rod 8, so that one limiting rod 8 can control the batteries on both sides at the same time. The paddles 9 in every two adjacent limiting frames 7 are staggered to avoid mutual interference between the limiting frames 7.

[0024] The side wall of the upper cover 2 is rotatably equipped with control buttons 10. The number of control buttons 10 on the surface of the upper cover 2 is adapted to the rotating rod 5. Each control button 10 is divided into an operation part and a control part. The operation part extends to the outside of the upper cover 2, and the control part extends into the lower housing 1 and abuts against the rotating rod 5, ensuring that each control button 10 can be adapted to and control a corresponding rotating rod 5. The end of the control button 10 abuts against the rotating rod 5. The control part of the control button 10 and the abutting surface of the rotating rod 5 are provided with mutually adapted limiting patterns to ensure that the control button 10 can effectively control the rotating rod 5.

[0025] Working principle description: First, with the upper cover 2 closed, the operator rotates the control knob 10. The control knob 10 drives the rotating rod 5 to rotate. When the control rod 5 rotates, it drives the limiting frame 7 to move to the end of the rotating rod 5 near the upper cover 2 via the thread 6. Then, the upper cover 2 is opened and the battery is placed vertically between the lower housing 1 and the limiting frame 7, ensuring that the battery is placed evenly as much as possible. Then, the upper cover 2 is closed. After closing the upper cover 2, the control knob 10 is reversed. When the control knob 10 flips, it drives the rotating rod 5 to reverse. The reversed rotating rod 5 drives the limiting frame 7 to move towards the battery until the paddles 9 on both sides of the limiting frame 7 contact the battery, making the rotation of the control knob 10 significantly obstructed. At this time, the operator opens the upper cover 2 to confirm the position of the limiting frame 7. If the paddles 9 on both sides of the limiting frame 7 are in contact with the battery, the upper cover 2 can be closed to complete the placement of the battery.

[0026] If the lever 9 does not contact the battery, close the top cover 2 and continue to rotate the control knob 10. Repeat the above operation until the lever 9 contacts the battery. If one side of the lever 9 on one side of a limiting rod 8 contacts the battery while the other side does not, continue to repeat the above operation. Move the limiting frame 8 so that one side of the lever 9 bends past the battery and the other side of the lever 9 continues to move until it contacts the battery. The operator repeats the above operation until the batteries in each placement cavity are restricted by the lever 9. At this time, one side of the battery is adjacent to other batteries, and the other side is restricted by the lever 9, so that it will not tilt. This ensures that both ends of the battery are always in contact with the contact piece 3, ensuring the normal use of the battery.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
