Embodiment Construction
[0012] Referring to FIG. 1 , the present invention includes a terminal 1 , a bush 2 , a polarity cover 3 , a rubber cover 4 , a sealing ring 5 , a connecting screw 6 , an adhesive 7 , a rubber sleeve 8 , and a middle cover 9 . The terminal 1 passes through the middle cover 9 and protrudes outward, the rubber cover 4 is fixedly connected with the polar cover 3, and the polar cover 3 and the rubber cover 4 are sleeved above the terminal part protruding from the middle cover 9 (the rubber cover 4 can be connected with the Terminal 1 contact connection), polarity cover 3 is fixedly connected with terminal 1, connecting screw 6 (used to fix the electrode lead wire) passes through rubber cover 4 and is threaded with terminal 1; terminal 1 is sleeved with bushing 2, the bushing 2 and terminal 1 are bonded by adhesive, and a rubber sleeve 8 is provided between the bushing 2 and the middle cover 9 .
[0013] The bushing 2 of the present invention can be an annular cup-shaped structure,...

The invention relates to a retractable terminal structure of a lead-acid storage battery, which comprises a middle cover of the lead-acid storage battery, a terminal, a polarity hood and a rubber hood, wherein the terminal passes through the middle cover and extends outward; a bush is sleeved on the terminal; the bush is bonded with the terminal through a bonding agent; and a rubber sleeve is arranged between the bush and the middle cover. Because the structure is adopted in the invention, when a plate grid grows and acts on the terminal to extend upward, the bush slides upward with the terminal; in the upward moving process of the terminal, the combined part of the rubber hood and the terminal is simultaneously deformed and stretched, the polarity hood can not move upward to be hung in the air, the force acting on the terminal caused by production of the battery plate grid is digested, and the occurrence of leakage of electrolyte is avoided, thereby achieving the purpose of protecting equipment and environment; and in addition, because the rubber sleeve has elasticity and a certain amount of lubricating oil is smeared on the bush, the bush is still in close contact with the rubber sleeve in the upward moving process of the bush, thus gas and acid can not leak.
Description
technical field [0001] The invention relates to a retractable terminal structure of a lead-acid storage battery. Background technique [0002] At present, for traditional lead-acid batteries, in order to prevent the leakage of the electrolyte, a rigid and firm bond is carried out between the battery terminals and the middle cover through adhesives such as epoxy resin. However, during the use of lead-acid batteries, the grid will continue to grow and deform, and the growth force of the grid in the longitudinal direction of the battery directly acts on the battery terminals. [0003] Grid growth For small lead-acid batteries, due to the short growth length, the growth force of the grid is not enough to destroy the bond between the battery terminal and the middle cover, so it is suitable to use this rigid bond. But for large lead-acid batteries, especially thin lead-acid batteries (the ratio of height to width is greater than 2), the growth of the grid in the longitudinal dire...
