Description

Technical Field

[0001] The utility model relates to the technical field of battery testing equipment, in particular to an alkaline battery quality testing device. Background Art

[0002] Alkaline batteries, also known as alkaline dry batteries, alkaline zinc-manganese batteries or alkaline manganese batteries, are the best performing variety in the zinc-manganese battery series and are suitable for use with large discharge capacities and for long periods of time.

[0003] A Chinese patent with publication number CN217360239U discloses an alkaline zinc-manganese dry battery service life detection device, including a pointer multimeter body and a power-on sheet, wherein a limit slot is provided on the side wall of the pointer multimeter body, and a clamping assembly is slidably penetrated through the inner wall of the limit slot; the clamping assembly includes a battery placement box slidably connected to the limit slot, an oblong slot is provided inside the battery placement box, and a sliding rod is slidably connected to the inner wall of the oblong slot, a clamping plate is welded to one end of the sliding rod close to the inner cavity of the battery placement box, and a threaded push rod is threadedly penetrated through the end of the battery placement box far from the limit slot; by providing the clamping assembly and the threaded push rod, the loosening of the battery during measurement by the existing device, which leads to deviation in the measurement result, is conducive to tightly clamping the battery for measurement, and increases the accuracy of the device.

[0004] This patent uses a clamping assembly combined with a threaded push rod to ensure the firmness of the connection between the battery and the power supply plate.

[0005] However, the threaded push rod and the clamping plate are rigidly connected, that is, the clamping plate moves the same length in the limit slide slot as the threaded push rod moves. When operators are trying to match batteries of different lengths, they rely on experience and feel to rotate the threaded push rod, which causes the threaded push rod to rotate too violently, causing the power-carrying plate to collide violently with one end of the battery, which in turn causes damage to the battery or the power-carrying plate, reducing the service life of the detection device. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an alkaline battery quality inspection device, which has the effect of eliminating the excess movement length of the placement block through the elastic deformation of the spring, thereby avoiding the violent collision between the power-carrying plate and one end of the battery, avoiding damage to the power-carrying plate and one end of the battery, and thus improving the service life of the quality inspection device.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] An alkaline battery quality inspection device comprises a multimeter body, a power supply sheet and a carrier for placing batteries, a screw rod is horizontally passed through one end of the carrier for being threadedly connected to the carrier, a connecting plate is rotatably arranged at one end of the screw rod located inside the carrier, two placing blocks are arranged inside the carrier, one of the placing blocks is fixed to one side of the inner wall of the carrier, two springs are arranged between the other placing block and the connecting plate, and two ends of each spring are respectively connected to one side of the connecting plate and one side of the corresponding placing block;

[0009] The battery is located between the two placement blocks.

[0010] In a preferred example, the utility model can be further configured as follows: two guide rods are symmetrically and slidably penetrated on the connecting plate, and one end of the two guide rods is fixed to one side of the corresponding placement block;

[0011] The spring sleeve is arranged on the outer peripheral surface corresponding to the guide rod.

[0012] In a preferred example, the utility model can be further configured as follows: an arc-shaped groove is opened at the bottom of the inner hole wall of the support platform, and the battery part is located inside the arc-shaped groove.

DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1-Figure 3 As shown, the utility model discloses an alkaline battery quality inspection device, which includes a multimeter body 1, two power supply sheets 11 connected to the multimeter body 1 through wires, and a supporting platform 12 for placing batteries.

[0027] The battery is placed in the carrier 12, and in order to prevent the battery from rolling randomly when placed in the carrier 12, an arc groove 4 is provided at the bottom of the inner hole wall of the carrier 12, and the battery part is located inside the arc groove 4.

[0028] At the same time, in order to further strengthen the fixation of the battery position, a plurality of straps 6 are arranged on the top of the carrier 12, one end of the plurality of straps 6 is fixed to the top of the carrier 12, a first Velcro 61 is arranged on the portion of the plurality of straps 6 close to the battery, and a plurality of second Velcro 62 is arranged on the other side of the top of the carrier 12, and the position of the second Velcro 62 corresponds to the position of the first Velcro 61. In this embodiment, the number of the straps 6 and the second Velcro 62 are both three.

[0029] A screw rod 13 is horizontally passed through one end of the carrier platform 12, and the screw rod 13 is threadedly connected to the carrier platform 12. A connecting plate 14 is rotatably provided at one end of the screw rod 13 located inside the carrier platform 12. The connecting plate 14 is located inside the carrier platform 12, and the connecting plate 14 is slidably connected to the carrier platform 12, and the connecting plate 14 moves along the straight line direction where the screw rod 13 itself is located.

[0030] Two placement blocks 2 are arranged in the support platform 12, one of the placement blocks 2 is fixed to one side of the inner wall of the support platform 12, and two springs 21 are arranged between the other placement block 2 and the connecting plate 14, and the two ends of each spring 21 are respectively connected to one side of the connecting plate 14 and one side of the corresponding placement block 2. In this embodiment, the spring 21 is a lightweight spring 21.

[0031] In order to ensure that the moving direction of the movable placement block 2 remains unchanged, two guide rods 3 are symmetrically slidably penetrated on the connecting plate 14, and one end of the two guide rods 3 is fixed to one side of the corresponding placement block 2. The spring 21 is sleeved on the outer peripheral surface of the corresponding guide rod 3. The battery is located between the two placement blocks 2.

[0032] One side of the two placement blocks 2 symmetrically protrudes outward to form a clamping block 5 . A first placement groove 51 is formed on the top of each of the two clamping blocks 5 . One side of the first placement groove 51 passes through the corresponding clamping block 5 .

[0033] Part of the power-carrying sheet 11 is located in the corresponding two first placement grooves 51 , and one side of the power-carrying sheet 11 is in contact with one side of the corresponding placement block 2 .

[0034] The implementation principle of the above embodiment is:

[0035] The operator first inserts the two power-carrying sheets 11 into the corresponding first placement slots 51 to preliminarily fix the power-carrying sheets 11 on the corresponding placement blocks 2 .

[0036] Next, the operator places the battery in the arc groove 4 , with one end of the battery fitting against a side of the arc groove 4 close to the fixed placement block 2 .

[0037] Next, the operator uses three straps 6 to fix the battery, and parts of the surfaces of the three straps 6 are in contact with parts of the surfaces of the battery.

[0038] After the preparation work is completed, the operator rotates the screw rod 13, and the screw rod 13 drives the connecting plate 14 to move. When the movable placement block 2 does not contact the battery, the placement block 2 moves with the connecting plate 14, and at this time, the two springs 21 are in a natural state.

[0039] When the power-carrying sheet 11 placed on one side of the movable placement block 2 contacts the battery, the operator can clearly feel that the force used to rotate the screw 13 becomes larger. At this time, as the screw 13 rotates, the two springs 21 are in an elastically compressed state.

[0040] The distance between the connecting plate 14 and the corresponding placement block 2 is shortened.

[0041] When the operator feels that the rotation force state is different, the rotation of the screw 13 is stopped immediately.

[0042] Finally, the operator starts the multimeter to perform quality inspection on the battery.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
