Detailed Description

As shown in figures 1-5, a quantitative acid adding kettle capable of being automatically opened by pressing down comprises a kettle body 1, an inner cavity for storing acid liquor is arranged in the kettle body 1, in one embodiment, the inner cavity of the kettle body 1 comprises 6 grids corresponding to 6 single grids of a storage battery,

a plurality of vertical lower pressing blocks 3 are arranged at the positions of the two outer side walls of the kettle body 1 close to the middle lower part. The bottom surface of the kettle body 1 is provided with a lower acid pipe 2 communicated with the inner cavity of the quantitative acid adding kettle, each grid of the inner cavity of the kettle body 1 is correspondingly provided with one lower acid pipe 2, and the bottom end of each lower acid pipe 2 is provided with a socket 4 which is matched with an acid adding hole column on the top surface of a storage battery in a plugging way. The acid discharging pipe 2 is internally provided with a control valve for controlling automatic acid discharging, the control valve comprises a trigger rod 5, the trigger rod 5 comprises a mandril 51 extending into the storage battery during use and a block 52 installed in the acid discharging pipe 2, the acid discharging pipe 2 is internally provided with an installation section 23 with a reduced inner diameter, the block 52 is provided with a closed valve state clamped into the installation section 23 to block the acid discharging pipe 2, and an open valve state that the block 52 is ejected out of the installation section 23 due to the mandril 51 pushing against the storage battery to ensure that the acid discharging pipe 2 is unblocked when the quantitative acid adding kettle is pressed downwards. In a preferred embodiment, the block 52 is spherical and the bottom end is connected to the top rod 51.

The block 52 is an interference fit with the mounting section 23. The acid dropping pipe 2 has a stopper ring 24 below the installation section 23 to restrict downward movement of the block 52. The acid dropping tube 2 has a chamfer 25 above the mounting section 23 to facilitate the mounting of the slug 52 to the mounting section 23. Whole trigger lever 5, including ejector pin 51 and sprue 52, holistic density is less than the density that adds the acid of acid use, makes sprue 52 deviate from the back from installation section 23 like this, and trigger lever 5 alright can float, and follow-up does not influence the acid process, just also need not make trigger lever 5 be in under the trigger condition always.

The acid discharging pipe 2 comprises a mounting pipe 21 which is integrally formed with the kettle body 1, and a spout 22 of which the top end is sleeved with the mounting pipe 21, the mounting section 23 is positioned in the spout 22, and the insertion port 4 is positioned on the bottom surface of the spout 22. The spout 22 can be made of acid-resistant rubber and has certain flexibility, so that the storage battery cannot be damaged when the spout 22 is in plug-in fit with the acid injection hole column of the storage battery. When the kettle is used, the trigger rod 5 can be installed in the spout 22, and then the spout 22 is fixedly sleeved with the installation pipe 21 on the bottom surface of the kettle body 1, so that the trigger rod 5 is convenient to install.

The lower acid pipe 2 is positioned on one side of the bottom surface of the kettle body 1, the other side of the bottom surface of the kettle body 1 is also provided with a supporting leg 6, so that when the quantitative acid adding kettle is assembled on a storage battery, the lower acid pipe 2 is in plug-in fit with an acid injection hole column on the top surface of the storage battery, and the supporting leg 6 can be propped against other positions on the top surface of the storage battery, so that the quantitative acid adding kettle is stable when assembled on the storage battery and is not easy to overturn.

The utility model discloses quantitative acid adding kettle that automatic opening is pushed down when using, assemble quantitative acid adding kettle earlier, make ejector pin 51 of trigger bar 5 wear out from spout 22 below, the sprue 52 is installed in the installation section 23 of spout 22, then install quantitative acid adding kettle on each battery, interface 4 and the notes acid hole post grafting of battery top surface of spout 22 bottom are on the ground but not grafting at this moment (of course can also directly peg graft and target in place, produce certain deformation through the pushing down of spout 22 when subsequent pushing down and realize triggering of trigger bar 5), ejector pin 51 stretches into the battery but does not touch the utmost point crowd inside the battery, pour into the required amount of acidizing fluid into the quantitative acid adding kettle, at this moment because the control valve is in the closed valve state, stay in quantitative acid adding kettle and can not flow into the battery, treat the battery that many quantitative acid adding kettles are equipped with in unison through specific equipment, the quantitative acid adding kettle is pressed down uniformly to trigger the control valve to be opened, and the synchronous quantitative acid adding is started for a plurality of storage batteries in the same batch.
