Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-6As shown, the present invention proposes a battery latch anti-loosening device, comprising a box body 1, a battery slot 2 for accommodating batteries on the top of the box body 1, two battery bodies 4 installed side by side inside the battery slot 2, and two output electrode plates 3 fixedly installed on the right side wall of the inner cavity of the battery slot 2. The two output electrode plates 3 are respectively tightly abutted against the right end of the two battery bodies 4 to draw out the electrical energy of the battery. The two battery bodies 4 are installed in opposite directions to ensure accurate output of electrical energy from the two battery bodies 4. A cover plate 5 is detachably connected to the top of the box body 1 by means of latches and screws to close the battery slot 2. Mounting plates 8 are fixedly installed at both ends of the box body 1 to fix the entire device inside the equipment or in a designated position.

[0026] The battery compartment 2 is equipped with a fixing mechanism 6 for fixing the two battery bodies 4, and the bottom of the cover plate 5 is equipped with a pressing mechanism 7 for limiting the top of the two battery bodies 4.

[0027] Example 1, as Figure 2-5 As shown, the fixing mechanism 6 is located inside the battery slot 2 and is mainly used to clamp and fix the two battery bodies 4 from the axial direction of the battery.

[0028] The fixing mechanism 6 includes a slide plate 61, which is slidably connected to the left side of the box 1 and extends to the inside of the battery slot 2 at its right end. A movable plate 62 is fixedly installed on the right side of the slide plate 61, which is also located inside the battery slot 2. A connecting electrode plate 63 is fixedly installed on the right side of the movable plate 62. The connecting electrode plate 63 abuts against the left ends of the two battery bodies 4 to connect the two batteries in series and conduct current.

[0029] A fixing block 64 is fixedly installed on the top of the skateboard 61. The fixing block 64 is located on the left side of the box body 1. A top block 65 is fixedly installed on the left side of the box body 1 and above the fixing block 64. A positioning component 66 is provided inside the top block 65. The positioning component 66 is connected to the fixing block 64 below and is used to position the fixing block 64, thereby locking the position of the skateboard 61 and the movable board 62.

[0030] In addition, a set of guide components 67 is provided on the outer end face of the movable plate 62, i.e. the front and rear sides, to ensure that the movable plate 62 moves smoothly and horizontally in the battery slot 2 and prevent it from tilting.

[0031] When the slide plate 61 is pushed inward, it causes the movable plate 62 and the connecting electrode plate 63 to move to the right, thereby pressing the two battery bodies 4 tightly onto the output electrode plate 3 on the right side to achieve axial fixation. This fixed state can be locked by the fixing block 64, the top block 65 and the positioning component 66.

[0032] Example 2, as Figure 4As shown, the positioning component 66 includes a positioning groove 661 formed on the top of the fixing block 64, and an installation groove 662 formed on the bottom of the top block 65. The bottom end of a sliding rod 663 passes through the top of the top block 65 and slides into the interior of the installation groove 662. A right-angled trapezoidal block 664 is fixedly installed at the bottom of the sliding rod 663. The right-angled trapezoidal block 664 is slidably connected to both the positioning groove 661 and the installation groove 662. A first spring 665 is fitted on the top of the right-angled trapezoidal block 664 and around the sliding rod 663. The top end of the first spring 665 is fixedly connected to the inner top wall of the installation groove 662. A pull block 666 is fixedly installed on the top end of the sliding rod 663 for easy operation.

[0033] In its natural state, the elastic force of the first spring 665 pushes the right-angled trapezoidal block 664 downward, causing it to engage in the positioning groove 661 of the fixed block 64. At this time, the slide plate 61 is locked and the battery is clamped.

[0034] When the battery needs to be removed, pull the pull block 666 upwards, which will move the sliding rod 663 and the right-angled trapezoidal block 664 upwards, causing the right-angled trapezoidal block 664 to disengage from the positioning groove 661, thereby releasing the lock on the fixing block 64. The slide plate 61 will move to the left under the action of the battery's elasticity or external force, and the battery will be released.

[0035] The inclined design of the right-angled trapezoidal block 664 allows it to move upward and slide past the fixed block 64 even without pulling the pull block 666 when the slide plate 61 needs to be installed urgently or pushed forward quickly. Then, under the action of the rebound force of the first spring 665, it automatically locks into the positioning groove 661, achieving quick locking.

[0036] In embodiment 3, the guide assembly 67 includes two guide grooves respectively opened on the front and rear side walls of the inner cavity of the battery slot 2. Guide blocks are fixedly installed on the front and back of the movable plate 62, and the two guide blocks are slidably connected to the corresponding two guide grooves.

[0037] The guide block and guide groove ensure that the movable plate 62 and the connecting electrode plate 63 on it can only move smoothly along the preset straight path, avoiding rotation or jamming of the movable plate 62 during movement, and ensuring the alignment and reliable contact between the connecting electrode plate 63 and the battery end.

[0038] Example 4, as Figure 6 As shown, the compression mechanism 7 is located at the bottom of the cover plate 5 and is mainly used to limit and press the top of the two battery bodies 4 from the radial direction of the battery.

[0039] The extrusion mechanism 7 includes a second spring 71 and an extrusion plate 72. The top end of the second spring 71 is fixedly connected to the bottom of the cover plate 5, and the bottom end of the second spring 71 is fixedly connected to an extrusion plate 72.

[0040] After the cover plate 5 is closed, under the elastic force of the second spring 71, the bottom of the pressing plate 72 will continuously press against the top of the two battery bodies 4.

[0041] Under the action of the compression plate 72, the battery body 4 can be effectively prevented from jumping or loosening in the vertical direction, and works in conjunction with the fixing mechanism 6 to form a comprehensive fixation.

[0042] Working principle: In use, the battery latch anti-loosening device works as follows: First, open the cover 5 and place the two battery bodies 4 side by side into the battery slot 2 of the housing 1, ensuring the right end of the battery contacts the fixed output electrode plate 3. Then, push the slide plate 61 to the right. The slide plate 61, through the movable plate 62, moves the connecting electrode plate 63 to the right until the connecting electrode plate 63 is tightly abutted against the left ends of the two battery bodies 4. At this point, the two battery bodies 4 are tightly clamped between the output electrode plate 3 and the connecting electrode plate 63, completing the circuit connection and initial axial fixation. When the slide plate 61 is pushed to the designated position, the fixing block 64 at its top will move under the top block 65. As the fixing block 64 moves upward, its top inclined surface will contact and compress the inclined surface of the right-angled trapezoidal block 664. This compressive force will overcome the elastic force of the first spring 665. Push the right-angled trapezoidal block 664 upward. When the positioning groove 661 of the fixing block 64 moves to align with the right-angled trapezoidal block 664, under the downward pressure generated by the recovery deformation of the first spring 665, the right-angled trapezoidal block 664 will quickly be inserted into the positioning groove 661. At this time, the fixing block 64 is locked, and the entire fixing mechanism 6 cannot retract to the left, thus firmly locking the battery axially. Then, the cover plate 5 is closed on the box body 1. During the process of closing the cover plate 5, the pressing plate 72 at its bottom will first contact the top of the battery body 4. As the cover plate 5 is fully closed, the second spring 71 is compressed, generating a continuous downward elastic force. Through the pressing plate 72, it is evenly applied to the top of the two battery bodies 4. This downward pressure further restricts the possibility of the battery jumping vertically in the battery slot 2, completing the radial clamping.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
