Description

Technical Field

[0001] This application relates to the field of liquid cooling pipeline connection device technology, and more specifically, to a connection device with improved locking reliability. Background Technology

[0002] Currently, new energy vehicle and energy storage cooling piping systems have multiple branches, especially energy storage cooling piping systems which may have dozens or even hundreds of branches. To improve cooling efficiency and the uniformity of battery pack temperature distribution, multiple T-joints of different specifications are typically added to achieve uniform distribution of cooling medium in each branch. This results in inconsistent branch structures, increasing manufacturing costs and the uniformity of flow distribution, thus increasing design difficulty and time, and significantly raising the requirements for error prevention during installation. Although devices with flow regulation functions have been applied, there are still problems where the regulating switch posture can change due to misoperation or external vibrations and pulse pressure. Utility Model Content

[0003] The purpose of this utility model is to provide a connection device with improved locking reliability. It is provided with an adjustment knob, an upper housing, a lower housing, an anti-rotation sleeve, and a secondary knob. The rear end of the upper housing is connected and penetrates the front end of the lower housing. The lower end of the adjustment knob has a through hole and extends into the interior of the lower housing. The upper side of the rear end of the lower housing has a mounting hole. The lower end of the adjustment knob passes through the mounting hole and is rotatably connected to the lower housing. The upper end of the adjustment knob has a detachable anti-rotation sleeve. The upper side of the adjustment knob has a detachable secondary knob.

[0004] Furthermore, the lower end of the adjustment knob has a through hole, and both sides of the lower end of the adjustment knob are provided with inner sealing gaskets.

[0005] Furthermore, the bottom of the adjustment knob is provided with an inner sealing ring.

[0006] Furthermore, an inner sealing ring II is provided between the inner sealing gasket at the front end and the rear end of the upper housing.

[0007] Furthermore, the upper housing is provided with an outer sealing ring at both the front end and the outer side of the middle end.

[0008] Furthermore, the lower housing surface is provided with an angle marking groove to indicate the rotation position of the adjustment knob.

[0009] Furthermore, the anti-rotation sleeve and the secondary knob form a two-way locking mechanism. When the secondary knob is in the locked state, the anti-rotation sleeve restricts the rotation of the adjustment knob; when the secondary knob is in the loosened state, the adjustment knob can rotate freely to adjust the flow rate or close the channel.

[0010] Furthermore, the axis of the through hole of the adjustment knob intersects perpendicularly with the through channel of the upper and lower housings.

[0011] Furthermore, the junction of the upper and lower housings forms an annular chamber for accommodating the inner sealing gasket.

[0012] Compared with existing technologies, this utility model employs a flow regulating valve with a locking sleeve mechanism, combined with angle markings on it, to facilitate easy confirmation of the knob position, thereby enabling arbitrary adjustment and uniform distribution of flow in each branch. Furthermore, it achieves a unified structure for each branch, reducing manufacturing costs and facilitating installation. Simultaneously, the locking mechanism effectively prevents unnecessary changes in the adjustment switch's posture. Attached Figure Description

[0021] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0022] A connection device with improved locking reliability is used in new energy vehicles or energy storage cooling pipeline systems to realize multi-branch flow regulation. Specifically, it includes an adjustment knob 1, an upper housing 2, a lower housing 3, an anti-rotation sleeve 8, and a secondary knob 9. The rear end of the upper housing 2 is connected and penetrates the front end of the lower housing 3. The upper side of the rear end of the lower housing 3 is provided with a mounting hole. The lower end of the adjustment knob 1 has a through hole that extends into the interior of the lower housing 3, and the lower end of the adjustment knob 1 is rotatably connected to the rear end of the lower housing 3. The upper end of the adjustment knob 1 is provided with a detachable anti-rotation sleeve 8, and the anti-rotation sleeve 8 is detachably connected to the adjustment knob 1 through a snap-fit ​​structure.

[0023] A detachable secondary knob 9 is provided on one side of the upper end of the adjustment knob 1. The stability of the flow adjustment state can be ensured through the cooperative locking mechanism of the secondary knob 9 and the anti-rotation sleeve 8.

[0024] The lower end of the adjustment knob 1 has a through hole, and both sides of the lower end of the adjustment knob 1 are provided with inner sealing gaskets 6.

[0025] The bottom of the adjustment knob 1 is equipped with an inner sealing ring 4.

[0026] An inner sealing ring 5 is provided between the inner sealing gasket 6 at the front end and the rear end of the upper housing 2.

[0027] The upper housing 2 has an outer sealing ring 7 on both the front end and the outer side of the middle end.

[0028] The lower housing 3 has an angle marking groove on its surface to indicate the rotation position of the adjustment knob, which facilitates precise flow adjustment.

[0029] The anti-rotation sleeve 8 and the auxiliary knob 9 form a two-way locking mechanism. When the auxiliary knob 9 is in the locked state, the anti-rotation sleeve 8 restricts the rotation of the adjusting knob 1; when the auxiliary knob 9 is in the loosened state, the adjusting knob 1 can rotate freely to adjust the flow rate or close the channel. This prevents misoperation or deviation caused by vibration. When the flow rate needs to be adjusted, first loosen the auxiliary knob 9, and then operate the adjusting knob 1.

[0030] The axis of the through hole of the adjustment knob 1 intersects perpendicularly with the through channel of the upper housing 2 and the lower housing 3.

[0031] The joint between the upper housing 2 and the lower housing 3 forms an annular cavity for accommodating the inner sealing gasket 6. Furthermore, the entire connecting device is injection molded, and each sealing component is made of elastic rubber material.

[0032] This utility model utilizes a mechanical locking mechanism with dual knobs and an anti-rotation sleeve to clearly define the locking function of the secondary knob 9. Radial sealing is achieved through the inner sealing gasket 6, end-face sealing is achieved through inner sealing ring 4 / inner sealing ring 5, and external sealing ring 7 ensures sealing of the external pipeline. This multi-ring design prevents media leakage.

[0033] The method of using this utility model is as follows:

[0034] This device is suitable for applications such as battery packs in new energy vehicles and cooling pipelines in energy storage systems. It enables unified control of branch flow, improving system reliability and maintenance efficiency. When adjusting flow or closing a channel, the auxiliary knob 9 should be loosened first, followed by rotating the adjusting knob 1 to close the pipeline or adjust the flow. When the auxiliary knob 9 is locked, the adjusting knob 1 cannot be rotated for adjustment, effectively preventing unnecessary changes in the position of the adjusting knob 1.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
