Description

Technical Field

[0001] This utility model relates to the field of portable structure technology, and in particular to a portable structure for a mobile battery charge and discharge tester. Background Technology

[0002] Portable structures for mobile battery charge / discharge testers are auxiliary devices designed to improve the portability of the tester, allowing for easy transfer between different usage scenarios. They are defined as follows: through specific mechanical structures and connection methods, they are integrated with the main body of the battery charge / discharge tester, providing a functional module that is easy to hold, drag, or carry. Common portable structures include components such as telescopic rods, wheels, handles, and shoulder straps. The telescopic rod can be adjusted in length by stretching and retracting to accommodate different user operating heights; the wheels allow the instrument to be pushed on the ground, reducing the burden of carrying; and the handles and shoulder straps provide diverse carrying options for short-distance transport or when there is no flat ground.

[0003] Currently, to achieve convenient portability, most portable battery charge / discharge testers use an embedded telescopic rod as their primary portable structure. This design embeds the telescopic rod into a pre-drilled slot on one side of the instrument, achieving its telescopic function through complex internal latches and sliding rails, thus ensuring the overall integrity and structural stability of the instrument to a certain extent. However, when the telescopic rod malfunctions, such as a lock failure, sliding rail jamming, or rod breakage, repair becomes extremely difficult. Due to its embedded installation, repair personnel must first remove numerous fixing components from the tester's outer casing and then carefully separate the internal structure connected to the rod to access the faulty part. This process is not only cumbersome but also highly susceptible to accidental contact with the tester's internal precision electronic components during disassembly, causing secondary damage. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a portable structure for a mobile battery charge and discharge tester to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a portable structure for a mobile battery charge / discharge tester, comprising a tester body and two symmetrically arranged telescopic rods. The front of each of the two telescopic rods is in contact with the back of the tester body. A base plate is fixedly connected to the bottom of each of the two telescopic rods. Several symmetrically arranged casters are fixedly connected to the bottom of the base plate. The top surface of the base plate is in contact with the bottom surface of the tester body. Two symmetrically arranged locking bolts are rotatably connected to the bottom of the base plate. The threaded portions of the two locking bolts are threadedly connected to the tester body. Two symmetrically arranged frames are fixedly connected to the back of the tester body. Two symmetrically arranged control plates are slidably connected to the inner wall of each frame. A spring is fixedly connected between the two control plates. Two locking plates are fixedly connected to the side of each control plate away from the spring. Several locking plates penetrate the frames and engage with the telescopic rods.

[0007] Preferably, in any of the above embodiments, the inner side of the telescopic rod is provided with a slot, and several of the slots are connected to the telescopic rod through the frame.

[0008] Preferably, in any of the above solutions, a number of positioning pins are fixedly connected to the back of the main body of the tester, and two symmetrically arranged positioning holes are opened on the front of each telescopic rod. The positioning pins are slidably connected to the telescopic rod through the positioning holes.

[0009] Preferably, in any of the above solutions, the top surface of the base plate is fixedly connected to two symmetrically arranged T-shaped guide plates, and both T-shaped guide plates are slidably connected to the main body of the testing instrument.

[0010] Preferably, the bottom surface of the tester body has two symmetrically arranged threaded holes, and the screw portions of the two locking bolts are threadedly connected to the tester body through the threaded holes.

[0011] Preferably, in any of the above embodiments, the length of the frame is equal to the distance between the two telescopic rods, and the frame is perpendicular to the telescopic rods.

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

[0013] 1. Addressing the issues of complex repairs and potential damage to internal components associated with traditional mobile battery charge / discharge testers' embedded telescopic rods, this portable design utilizes components such as a locking plate and frame for easy assembly and disassembly. When the telescopic rod malfunctions, there's no need to disassemble the main tester casing. Simply press the control board to allow the locking plate to retract against the spring force, disengaging from the telescopic rod's slot. The telescopic rod, along with the base plate and casters, can then be removed as a whole. The base plate is threadedly connected to the main tester body using locking bolts; loosening these bolts allows for easy separation. This modular design avoids interference with the tester's internal structure, allowing maintenance personnel to directly inspect or replace the faulty telescopic rod. This significantly simplifies the repair process, reduces the risk of damage to internal components due to complex disassembly, and effectively shortens equipment downtime for maintenance.

[0014] 2. This portable battery charge / discharge tester features a multi-component collaborative design that enables stable movement and convenient installation. During installation, first insert the positioning pin into the positioning hole of the telescopic rod for initial positioning. Next, slide the T-shaped guide plate on the base plate into the corresponding slot on the main body of the tester to ensure accurate positioning. Finally, tighten the locking bolts to securely connect the base plate to the main body of the tester. A spring pushes the control plate, causing the locking plate to engage with the slot on the telescopic rod, further securing the telescopic rod. In use, the casters allow for flexible movement of the tester on the ground, and the telescopic rod facilitates dragging the equipment. When adjustment or disassembly of the portable structure is required, reverse the operation for quick separation. This design ensures stability during movement of the tester while enabling rapid installation and disassembly of the portable structure, improving the applicability and efficiency of the equipment in different testing scenarios.

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0022] like Figures 1 to 5 As shown, a portable structure for a mobile battery charge / discharge tester includes a tester body 1 and two symmetrically arranged telescopic rods 2. The front of each telescopic rod 2 is in contact with the back of the tester body 1. A base plate 3 is fixedly connected to the bottom of each telescopic rod 2. Several symmetrically arranged casters 4 are fixedly connected to the bottom of the base plate 3. The top surface of the base plate 3 is in contact with the bottom surface of the tester body 1. Two symmetrically arranged locking bolts 5 are rotatably connected to the bottom of the base plate 3. The screw parts of the two locking bolts 5 are threadedly connected to the tester body 1. Two symmetrically arranged frames 6 are fixedly connected to the back of the tester body 1. Two symmetrically arranged control plates 7 are slidably connected to the inner wall of each frame 6. A spring 8 is fixedly connected between the two control plates 7. Two locking plates 9 are fixedly connected to the side of each control plate 7 away from the spring 8. Several locking plates 9 pass through the frame 6 and are engaged with the telescopic rods 2.

[0023] As an optional technical solution of this utility model, a slot 10 is provided on the inner side of the telescopic rod 2. Several locking plates 9 pass through the frame 6 and are engaged with the telescopic rod 2 through the slot 10. When the telescopic rod 2 is installed, the locking plates 9 automatically embed into the slot 10 under the elastic force of the spring 8, which can quickly lock the telescopic rod 2 onto the main body 1 of the testing instrument without complicated operation steps. During use, the tight fit between the slot 10 and the locking plates 9 can effectively prevent the telescopic rod 2 from loosening or falling off, ensuring that the testing instrument remains stable during movement.

[0024] As an optional technical solution of this utility model, a number of positioning pins 11 are fixedly connected to the back of the tester body 1, and two symmetrically arranged positioning holes 12 are opened on the front of each telescopic rod 2. The positioning pins 11 are slidably connected to the telescopic rod 2 through the positioning holes 12. The cooperation between the positioning pins 11 and the positioning holes 12 can not only limit the horizontal displacement of the telescopic rod 2, but also assist the locking plate 9 and the locking slot 10 to complete the locking, making the entire installation process smoother and more efficient. At the same time, this positioning structure can further enhance the stability of the connection between the telescopic rod 2 and the tester body 1 during the movement of the equipment, preventing the connection from loosening due to shaking.

[0025] As an optional technical solution of this utility model, two symmetrically arranged T-shaped guide plates 13 are fixedly connected to the top surface of the base plate 3. Both T-shaped guide plates 13 are slidably connected to the main body 1 of the testing instrument. When installing the base plate 3, the T-shaped guide plates 13 can slide quickly into the corresponding grooves of the main body 1 of the testing instrument, ensuring that the base plate 3 is accurately installed in place without repeated adjustments. The special structure of the T-shaped guide plates 13 can effectively restrict the horizontal movement of the base plate 3, preventing it from shifting or misaligning during equipment movement.

[0026] As an optional technical solution of this utility model, the bottom surface of the tester body 1 has two symmetrically arranged threaded holes 14. The screws of the two locking bolts 5 are threadedly connected to the tester body 1 through the threaded holes 14. By tightening the locking bolts 5, the base plate 3 can be firmly fixed to the tester body 1, ensuring that the entire portable structure will not loosen during use. The threaded connection has high connection strength and stability, and can effectively withstand various external forces generated during the movement of the tester.

[0027] As an optional technical solution of this utility model, the length of the frame 6 is equal to the distance between the two telescopic rods 2, and the frame 6 is perpendicular to the telescopic rods 2. This design ensures that the clamping plate 9 can accurately engage with the telescopic rods 2. The size adaptation of the frame 6 allows the clamping plate 9 to apply a uniform clamping force to the two telescopic rods 2 under the action of the spring 8, ensuring that the connection strength between the two telescopic rods 2 and the main body 1 of the testing instrument is consistent, and avoiding loosening of the telescopic rods 2 due to uneven force.

[0028] A portable structure for a mobile battery charge / discharge tester, the working principle of which is as follows:

[0029] 1) When the telescopic rod 2 malfunctions, there is no need to disassemble the outer shell of the tester body 1. Simply press the control board 7 to make the locking plate 9 retract against the elastic force of the spring 8 and disengage from the locking groove 10 of the telescopic rod 2. Then the telescopic rod 2, together with the base plate 3 and the caster wheel 4, can be removed as a whole.

[0030] 2) The base plate 3 is threadedly connected to the main body 1 of the tester via locking bolts 5. It can be separated by loosening the bolts during disassembly. This modular design avoids interference with the internal structure of the tester, and maintenance personnel can directly inspect or replace the faulty telescopic rod 2.

[0031] 3): Insert the positioning pin 11 into the positioning hole 12 of the telescopic rod 2 to complete the initial positioning; then slide the T-shaped guide plate 13 on the base plate 3 into the corresponding groove of the tester body 1 to ensure that the base plate 3 is in an accurate position; finally, tighten the locking bolt 5 to make the base plate 3 and the tester body 1 firmly connected.

[0032] In summary, the portable structure of this mobile battery charge / discharge tester allows for easy assembly and disassembly through components such as the locking plate 9 and the frame 6. When the telescopic rod 2 malfunctions, there is no need to disassemble the tester's main body 1. Simply press the control board 7 to cause the locking plate 9 to retract against the spring force of the spring 8, disengaging from the slot 10 of the telescopic rod 2. The telescopic rod 2, along with the base plate 3 and casters 4, can then be removed as a whole. The base plate 3 is threadedly connected to the tester's main body 1 via locking bolts 5; loosening the bolts during disassembly allows for separation. This modular design avoids interference with the internal structure of the tester. Maintenance personnel can directly inspect or replace the faulty telescopic rod 2, significantly simplifying the maintenance process, reducing the risk of damage to internal components due to complex disassembly, effectively shortening equipment downtime for maintenance, and achieving stable movement and convenient installation through the collaboration of multiple components. During installation, first insert the positioning pin 11 into the positioning hole 12 of the telescopic rod 2 to complete the initial positioning; then slide the T-shaped guide plate 13 on the base plate 3 into the corresponding groove of the tester body 1 to ensure the accurate position of the base plate 3; finally, tighten the locking bolt 5 to firmly connect the base plate 3 to the tester body 1. The spring 8 pushes the control plate 7, causing the locking plate 9 to engage with the slot 10 of the telescopic rod 2, further securing the telescopic rod 2.
