Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring device technology, and in particular to a forklift battery cover inner gap measuring device. Background Technology
[0002] Motor vehicle batteries, also known as car batteries, are an important component of automobiles. They are responsible for providing electrical energy for starting, ignition, lighting, and electronic equipment. For example, installing batteries in forklifts can provide the necessary power for the forklifts to perform various material handling tasks. Their performance will directly affect the normal use and driving safety of the vehicle.
[0003] To ensure the safety and stability of operation, according to relevant technical regulations, a certain gap must be maintained between the battery metal cover and the live parts of the battery to prevent short circuits or electrical fires. In related technologies, a common method for measuring the gap inside the battery cover is to use modeling clay and a ruler. A certain amount of modeling clay is placed on the live parts inside the battery, and as the metal cover closes, it deforms. After reopening, the height of the compressed clay is measured with a ruler to determine the size of the gap. However, during this measurement process, the modeling clay easily adheres to the inner wall of the metal cover, causing it to deform and elongate, leading to inaccurate measurement data. Furthermore, the modeling clay is easily wasted during large-scale measurements and is inconvenient to store when not in use.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] 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 in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] like Figures 1 to 7 The forklift battery cover internal gap measuring device shown includes: a support member 10, a pressing member 20, and a friction member 30. The support member 10 is transparent and hollow, and has a scale 10a and an air vent 10b on its outer side wall. The scale 10a is arranged along the axial direction of the support member 10, and the air vent 10b is arranged through the side wall at the bottom of the support member 10. One end of the pressing member 20 is arranged inside the support member 10 from the top opening of the support member 10. The friction member 30 is fixedly arranged at the end of the pressing member 20 located inside the support member 10, and is slidably connected to the inner side wall of the support member 10 as the pressing member 20 slides.
[0030] This invention features a dedicated gap measuring device that can be reused, avoiding waste during large-scale testing. The device has a simple overall structure, is easy to operate, and is easy to use, store, and carry. During the measurement process, the relative position of the pressing part 20 does not change arbitrarily as the battery cover is opened, thus greatly improving the accuracy of the measurement results.
[0031] By setting up a support member 10, a pressing member 20, and a friction member 30, when measuring the gap inside the battery cover, it is only necessary to pull the pressing member 20 out of the cavity of the support member 10 and record the scale reading 10a at the corresponding position of the friction member 30. When closing the battery cover, pressure is applied to the pressing member 20, causing the friction member 30 to slide along the inner wall of the support member 10, expelling the internal air from the air guide hole 10b. The friction between the friction member 30 and the inner wall of the support member 10 causes the pressing member 20 to stay in the set position. When opening, the corresponding scale 10a can be read according to the position of the friction member 30, thereby obtaining the size of the gap inside the battery cover based on the height difference of the movement.
[0032] Based on the above embodiments, the pressing member 20 includes a pressing head 21, an extension section 22, and a moving head 23 arranged coaxially. The pressing head 21 and the moving head 23 are respectively fixedly disposed at both ends of the extension section 22, and the shaft diameter of the pressing head 21 is larger than the shaft diameter of the extension section 22. The friction member 30 is fixedly disposed on the moving head 23. The extension section 22 connects the pressing head 21 and the moving head 23, providing sufficient moving space for the pressing member 20 to adapt to battery covers of different sizes. The top surface of the pressing head 21 contacts the battery cover and applies pressure to ensure that the friction member 30 can slide relative to the inner wall of the support member 10.
[0033] Based on the above embodiment, the extension section 22 is hollow inside to form a cavity 22a. The pressing head 21 and the moving head 23 seal the two ends of the cavity 22a. The hollow structure reduces the amount of material used, thereby reducing the overall weight and making the pressing member 20 lighter. This ensures that the pressure of the battery cover can reach the force needed to control the movement of the pressing member 20.
[0034] Based on the above embodiment, at least one reinforcing plate 22b is provided in the cavity 22a along the radial direction of the extension section 22. The two ends of the reinforcing plate 22b are fixedly connected to the opposite sides of the pressing head 21 and the moving head 23, respectively. The outer side of the reinforcing plate 22b is fixedly connected to the inner sidewall of the extension section 22, and the inner side is located on the axis of the extension section 22. The reinforcing plate 22b provides additional support, enhances the connection between the pressing head 21 and the moving head 23, and makes the structure of the entire pressing member 20 more stable. It reduces wear and deformation caused by long-term use or frequent operation, ensures the coaxiality between the pressing head 21 and the moving head 23, ensures the accuracy of the measurement results, and extends the service life.
[0035] Based on the above embodiment, four reinforcing plates 22b are provided, and the included angle between adjacent reinforcing plates 22b is 90°. The four reinforcing plates 22b are evenly distributed on the extension section 22 to ensure structural strength and more balanced force distribution, thereby ensuring the stability of the pressing member 20 during operation.
[0036] Based on the above embodiment, the outer shaft surface of the moving head 23 is provided with an annular groove 23a along the circumferential direction, and the inner side of the friction member 30 is provided with a protruding annular retaining head 30a, which is engaged in the groove 23a. Through the cooperation of the groove 23a and the retaining head 30a, the connection between the friction member 30 and the moving head 23 is more stable, reducing the error caused by unstable connection during measurement. It also makes the friction member 30 easy to install and remove, and easy to replace, thus improving the convenience of maintenance.
[0037] Based on the above embodiments, the support member 10 includes a base plate 11 and a cylinder 12. The base plate 11 is arranged in a horizontal direction, and the axis of the cylinder 12 is arranged perpendicular to the plane where the base plate 11 is located. One end of the cylinder 12 is open, and the other end is fixedly connected to the base plate 11. The pressing member 20 is arranged inside the cylinder 12 from the open end of the cylinder 12. The horizontal arrangement of the base plate 11 provides a stable support foundation, while the vertical arrangement of the cylinder 12 provides guidance and limiting function for the pressing member 20, making the overall structure more stable. The open end of the cylinder 12 allows the pressing member 20 to be easily inserted and removed, which is convenient for the operator to perform measurement and device setup.
[0038] Based on the above embodiments, the cross-sectional shape of the substrate 11 is circular or square, and the axis of the cylinder 12 is collinear with the center line of the substrate 11. The circular or square substrate 11 provides good structural symmetry, which helps to distribute the load evenly, reduce stress concentration, and thus improve the durability and stability of the device. The collinearity of the axis of the cylinder 12 with the center line of the substrate 11 ensures the symmetry and balance of the device, making the movement of the pressing member 20 and the friction member 30 smoother and ensuring the accuracy of the detection results.
[0039] Based on the above embodiment, a handle 13 is provided on the outer side of the open end of the cylinder 12, and the handle 13 is symmetrically distributed at both ends of the radial direction of the cylinder 12. The symmetrically distributed handle 13 provides better balance and stability, making it more stable when pressure is applied and reducing operation error. In addition, the handle 13 also makes it easier for the operator to pull the pressing part 20 out of the support part 10 before measurement, improving the ease of operation.
[0040] Based on the above embodiment, the aperture of the cylinder 12 is smaller than the shaft diameter of the friction element 30, and the inner side of the cylinder 12 is interference-fitted with the friction element 30. There is no gap between the inner side of the cylinder 12 and the friction element 30 due to the interference fit, which avoids loosening and ensures the stability of the movement of the friction element 30 within the cylinder 12. This reduces the error caused by the displacement of the friction element 30 during the measurement process and ensures the accuracy of the measurement results.
