[0002] In the production process of the airbag bag inflatable manifold for new energy battery cell assembly trays, the airtightness test of the manifold is a key step to ensure product performance and safety.

[0003] The current testing process is too time-consuming and inefficient, failing to meet the demands of large-scale production for rapid testing and efficient delivery, thus impacting the company's market competitiveness and economic benefits. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides an airtightness testing fixture for a manifold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: As one aspect of this utility model, a manifold airtightness testing fixture is proposed, which includes: a base and an upper pressure cover, wherein the base and the upper pressure cover are movably connected. The base is provided with a bottom mounting groove adapted to the busbar; a number of limiting pins are installed at intervals in the bottom mounting groove. A sealing groove is installed at the inner bottom of the upper pressure cover, and a sealing strip is installed in the sealing groove; An air intake channel is provided on the upper pressure cover.

[0006] Furthermore, the base and the upper cover are movably connected by a hinge.

[0007] Furthermore, it also includes a quick clamp, the fixed end of which is mounted on the upper pressure cover, and the base is equipped with a clamping seat that cooperates with the clamping strip of the quick clamp.

[0008] The beneficial effects of this utility model's manifold airtightness testing fixture are specifically reflected in the following aspects: the manifold is positioned by the upper pressure cover and the base; the upper threaded hole of the manifold is sealed by the sealing strip pasted in the upper pressure cover; the upper pressure cover and the base are clamped by a quick clamp to prevent leakage from the upper threaded hole of the manifold caused by high pressure during airtightness testing; the leakage at the bottom of the manifold can be directly observed by digging a groove in the bottom of the base; and the strength of the hollowed-out area is increased by adding a limit pin to prevent the manifold from bending and deforming when clamped. This greatly improves the efficiency of airtightness testing of the manifold in actual production operations and simplifies the airtightness testing process. Attached Figure Description

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] One embodiment of this application provides a busbar airtightness testing fixture, such as... Figures 1-4 As shown, it includes: a base 1 and an upper cover 2, the base 1 and the upper cover 2 being movably connected by a hinge 3; one end of the hinge 3 is connected to the long side of the base 1, and the other end of the hinge 3 is connected to the long side of the upper cover 2. The base 1 is provided with a bottom mounting groove 11 that is adapted to the busbar 4; a number of limiting pins 12 are installed at intervals in the bottom mounting groove 11, and the limiting pins 12 limit the busbar 4; the limiting pins 12 and the bottom mounting groove 11 form a limiting relationship for the busbar 4, and the other side of the bottom mounting groove 11 is convenient for observation during testing. A sealing groove 21 is installed at the inner bottom of the upper pressure cover 2, and a sealing strip 22 is installed in the sealing groove 21. The sealing strip 22 blocks the upper threaded hole of the manifold 4 under the action of the upper pressure cover 2. The upper pressure cover 2 is provided with an air inlet channel 23 for the introduction of test air source. The test air source enters the main channel of the manifold 4 from the air inlet channel 23.

[0013] Furthermore, it also includes a quick clamp 5, the fixed end of which is mounted on the upper pressure cover 2, and a card seat 6 that cooperates with the card strip of the quick clamp 5 is mounted on the base 1. The quick clamp 5 and the card seat 6 cooperate to lock the base 1 and the upper pressure cover 2. It should be noted that the structure of the quick clamp 5 is prior art and will not be described in detail here.

[0014] This embodiment uses an upper pressure cap and a base to position the manifold. A sealing strip attached to the upper pressure cap is used to seal the upper threaded hole of the manifold. A quick clamp is used to clamp the upper pressure cap and the base to prevent leakage from the upper threaded hole of the manifold caused by high pressure during the airtightness test. A groove is dug in the bottom of the base to allow direct observation of leakage at the bottom of the manifold. Additional limit pins are used to increase the strength of the cut-out area to prevent the manifold from bending and deforming when clamped. This greatly improves the efficiency of airtightness testing of the manifold in actual production operations and simplifies the airtightness testing process.

[0015] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
