Description

Technical Field

[0001] The invention relates to the field of lead-acid batteries, in particular to a portable lifting handle for lead-acid batteries. Background Art

[0002] After years of development, the problems of lead-acid batteries such as specific energy, cycle life, high and low temperature adaptability have been solved. In some core technologies, they have reached international standards and are increasingly entering the international market. As lead-acid batteries are widely used in more and more fields, their demand is growing significantly. However, there have always been problems with the transportation of larger lead-acid batteries. At present, in the production field of lead-acid batteries, batteries with a capacity of 1200Ah and below are usually carried manually. Due to the smooth surface of the battery, it is easy to fall off during production, packaging, installation and replacement, which causes danger. It is also time-consuming and labor-intensive, increasing production costs. Therefore, it is necessary to design a simple portable lifting handle that can be used to easily and quickly carry lead-acid batteries with one hand. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a simple portable lifting handle which can be used to conveniently and quickly carry a lead-acid battery by single-handed operation.

[0004] The technical solution to achieve the purpose of the present invention is: a portable lifting handle for a lead-acid battery, comprising a static handle, a movable handle, a spring and a support rod; the spring connects the static handle with the movable handle; a through hole is provided on the movable handle; one end of the support rod is hinged to the static handle, and the other end passes through the through hole; an external thread is provided on the outer periphery of the support rod below the movable handle; a pull rod is also provided at the bottom of the movable handle; a protrusion is provided on the pull rod; and a groove matching the protrusion is provided on the inner side of the support rod.

[0005] Furthermore, the diameter of the through hole is greater than the outer diameter of the support rod.

[0006] Furthermore, the protrusions are spherical, and adjacent spherical protrusions are arranged at equal intervals.

[0007] Furthermore, the grooves are circular grooves, and the number of the circular grooves is the same as the number of the spherical protrusions.

[0008] Furthermore, a lower groove is provided at the lower end of the support rod.

[0009] Furthermore, the groove edge of the lower groove is configured to be a smooth arc.

[0010] Furthermore, a rubber band is arranged in the groove of the lower groove.

[0011] After adopting the above technical solution, the present invention has the following positive effects:

[0012] (1) The support rod of the present invention is hinged to the static handle. The spring is compressed by holding the movable handle. The movable handle moves upward, driving the pull rod and the protrusion on the pull rod to move upward together. During the upward movement of the protrusion, an outward thrust is generated on the inner side of the support rod, causing the support rod to open outward. The external thread on the outer periphery of the support rod is in close contact with the internal thread inside the battery terminal, effectively preventing the battery from falling off during transportation. During the transportation of the battery, only a portable lifting handle is needed to carry the battery, and the entire transportation process is fast, efficient, time-saving and labor-saving, thereby saving production costs. In addition, the edge of the groove body of the lower groove is set to a smooth arc, which is convenient for the support rod to smoothly penetrate into the interior of the battery terminal. In addition, after being transported to the destination, the setting of the spring and rubber band plays an auxiliary role in the return of the protrusion, thereby ensuring that the support rod is tightened inward, thereby facilitating the separation of the portable lifting handle from the battery.

[0019] (Example 1)

[0020] See Figures 1 to 4The present invention has a portable lifting handle for a lead-acid battery, comprising a static handle 1, a dynamic handle 2, a spring 3 and a support rod 4. The spring 3 connects the static handle 1 with the dynamic handle 2 by welding. A through hole 8 is provided on the dynamic handle 2, and the aperture of the through hole 8 is greater than the outer diameter of the support rod 4. One end of the support rod 4 is hinged to the static handle 1, and the other end passes through the through hole 8. A pull rod 5 is also provided at the bottom of the dynamic handle 2, and the pull rod 5 is threadedly connected to the bottom of the dynamic handle 2. A spherical protrusion 51 is provided on the pull rod 5, and adjacent spherical protrusions 51 are arranged at equal intervals. The inner side of the support rod 4 is provided with a protrusion 51 that is aligned with the protrusion 51. The matching groove 41 is a circular groove, the diameter of the circular groove is slightly larger than the diameter of the spherical protrusion, the outer periphery of the support rod 4 below the movable handle 2 is provided with an external thread 6, the external thread 6 matches the internal thread in the lead-acid battery terminal 9, and the lower end of the support rod 4 is also provided with a lower groove 42, the groove edge of the lower groove 42 is set to a smooth arc, the outer diameter of the groove edge of the lower groove 42 is less than the outer diameter of the support rod 4 < the outer diameter of the external thread 6, and a rubber band 7 is arranged in the groove of the lower groove 42, and the size of the portable lifting handle can be customized according to the inner diameter of the battery terminal 9.

[0021] The working principle of the present invention is as follows: when in use, the lower end pull rod 5 and the support rod 4 of the portable lifting handle are inserted into the battery terminal 9, the movable handle 2 is held and moved upward, and the pull rod 5 at the bottom of the movable handle 2 moves upward accordingly, and the protrusion 51 on the pull rod 5 (that is, the spherical protrusion in Example 1, but not limited to the spherical protrusion) moves upward synchronously, and the protrusion 51 generates an outward supporting force on the inner side of the support rod 4, thereby stretching the support rod 4 outward, and the external thread 6 on the outer periphery of the support rod 4 is tightly contacted and locked with the internal thread inside the battery terminal 9. At this time, the battery can be directly transported to the destination, and then the movable handle 2 is directly released. Under the action of the spring 3 and the rubber band 7, the movable handle 2 drives the pull rod 5 to move downward, and the protrusion 51 returns to the groove 41 again, and the external thread 6 and the internal thread inside the battery terminal 9 are released from the locking state, and finally the lower end of the portable lifting handle can be directly pulled out from the battery terminal 9.

[0022] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
