Specifically, the quick-connect interface needs to be pre-assembled with rubber washers, retaining springs, nut seats and other components by the manufacturer. When users assemble the braking product by themselves, for the VOSS quick-connect connector assembly, they only need to insert the quick plug of the VOSS quick-connect connector assembly into the quick-connect interface pre-assembled on the braking product and make the retaining spring in the quick-connect interface snap into the slot on the quick plug to form a lock.

[0003] However, during the production and assembly process of the above-mentioned brake products, the quick-insert interfaces pre-assembled on the brake products often have the following problems: 1. Rubber washers and / or retaining springs are over-installed; 2. Rubber washers and / or retaining springs are missing; 3. The retaining spring performance fails, which is specifically reflected in the retaining spring failing to open when the quick plug is inserted into the quick-insert interface; 4. The retaining spring performance fails, which is specifically reflected in the insufficient rebound force or failure to rebound after the retaining spring is opened. Since users cannot determine whether the quick-insert interfaces pre-assembled on the brake products have the above-mentioned problems when assembling the above-mentioned brake products by themselves, brake products with the above-mentioned problems have great safety hazards after entering the market, and are likely to cause safety accidents.

[0031] Reference Figures 1 to 6 , a detection tool for a quick-connect interface according to an embodiment of the present invention includes a tool body 100 and a detection member 200 .

[0032] The tool body 100 is provided with an installation channel, which passes through the tool body 100 from front to back. The detection member 200 is movably arranged in the installation channel. When the detection member 200 is subjected to external force, it can move relative to the tool body 100, so that the front end of the detection member 200 can be inserted into the quick-insertion interface a. The front end of the detection member 200 is provided with a first protrusion 210 corresponding to the retaining spring b in the quick-insertion interface a. The front side of the first protrusion 210 is provided with a first guide surface 211, so that when the front end of the detection member 200 is inserted into the quick-insertion interface a, the first protrusion 210 can open the retaining spring b in the quick-insertion interface a, and then the front end of the detection member 200 can pass through the retaining spring b in the quick-insertion interface a and abut against the rubber gasket c in the quick-insertion interface a. The front end of the detection member 200 abuts against the retaining spring b in the quick-insertion interface a. When the rubber gasket c is used, the first protrusion 210 is misaligned with the retaining spring b in the quick-insertion interface a, so that the retaining spring b in the quick-insertion interface a can rebound and cooperate with the first protrusion 210 to lock the front end of the detection member 200. An elastic reset member is arranged between the detection member 200 and the tool body 100, and a second guide surface 212 is arranged on the rear side of the first protrusion 210, so that the front end of the detection member 200 cannot be locked or cannot be effectively locked when inserted into the quick-insertion interface a. It can be reset under the action of the elastic reset member. Among them, when the front end of the detection member 200 is inserted into the quick-insertion interface a and is effectively locked, the front end of the detection member 200 cannot be reset under the action of the elastic reset member. At this time, force needs to be applied to the detection member 200 to separate the front end of the detection member 200 from the retaining spring b in the quick-insertion interface a and reset it. It should be noted that when selecting an elastic return member, the elastic force of the elastic return member is less than or equal to the locking force formed by a qualified retaining spring b and the first protrusion 210, and the elastic force of the elastic return member is greater than the locking force formed by an unqualified retaining spring b and the first protrusion 210.

[0033] During the inspection, force is applied to the inspection member 200 so that the front end of the inspection member 200 moves relative to the tool body 100 and is inserted into the quick-insertion interface a. At this time, the external force applied to the inspection member 200 is removed. If the inspection member 200 cannot be locked or cannot be effectively locked, that is, the front end of the inspection member 200 is reset under the action of the elastic reset member, then the quality of the quick-insertion interface a is unqualified. Specifically, if the spring b in the quick-insertion interface a has insufficient rebound force after being opened, it cannot cooperate with the first protrusion 210 to effectively lock the front end of the inspection member 200. At this time, the front end of the detection member 200 can be reset under the action of the elastic reset member. If the retaining spring b in the quick-plug interface a cannot rebound after being opened, it cannot cooperate with the first protrusion 210 to lock the front end of the detection member 200. At this time, the front end of the detection member 200 can be reset under the action of the elastic reset member. If the retaining spring b in the quick-plug interface a cannot be opened, the front end of the detection member 200 cannot pass through the retaining spring b in the quick-plug interface a. The retaining spring b in the quick-plug interface a cannot cooperate with the first protrusion 210 to lock the front end of the detection member 200. Locked, at this time, the front end of the detection piece 200 can be reset under the action of the elastic reset piece. If the retaining spring b in the quick-plug interface a is not installed, the front end of the detection piece 200 cannot be locked. At this time, the front end of the detection piece 200 can be reset under the action of the elastic reset piece. If the retaining spring b in the quick-plug interface a is over-installed, the retaining spring b in the quick-plug interface a cannot be opened under the extrusion of the nut seat d, and the front end of the detection piece 200 cannot be locked. At this time, the front end of the detection piece 200 can be reset under the action of the elastic reset piece. If the rubber gasket c in the quick-plug interface a is over-installed, the front end of the detection piece 200 cannot pass through the retaining spring b in the quick-plug interface a, and the retaining spring b in the quick-plug interface a cannot cooperate with the first protrusion 210 to lock the front end of the detection piece 200. At this time, the front end of the detection piece 200 can be reset under the action of the elastic reset piece. The above-mentioned quick-plug interface detection tool can perform quality inspection on the quick-plug interface a pre-assembled on the brake product, which is beneficial to prevent the brake products on the market from causing safety accidents due to quality problems of the pre-assembled quick-plug interface a.

[0034] Reference Figure 4In some of the embodiments, a first limiting step 220 is provided at the front end of the detection member 200 corresponding to the retaining spring b in the quick-plug interface a, and the first limiting step 220 is located on the rear side of the first protrusion 210. Specifically, the first limiting step 220 is a right-angle step. If the rubber gasket c in the quick-plug interface a is not installed, the front end of the detection member 200 can be further inserted, so that the retaining spring b in the quick-plug interface a can cooperate with the first limiting step 220 to lock the front end of the detection member 200 after rebounding. At this time, even if force is applied to the detection member 200, the front end of the detection member 200 cannot be reset. The nut seat d needs to be removed and a tool needs to be used to separate the front end of the detection member 200 from the retaining spring b in the quick-plug interface a and reset it, so that the above-mentioned quick-plug interface detection tool has an anti-foolproof function, which is beneficial to prevent the brake products with the rubber gasket c missing in the quick-plug interface a from entering the market.

When the front end of the detection member 200 is inserted into the quick-insertion interface a and is effectively locked under the cooperation of the retaining spring b and the first protrusion 210 in the quick-insertion interface a, the indication mark moves to the reference mark. During detection, the front end of the tool body 100 can abut against the retaining spring b in the quick-insertion interface a. Or nut seat d, so as to position the tool body 100. If the quality of the quick-plug interface a is qualified, that is, the front end of the detection piece 200 inserted into the quick-plug interface a can be effectively locked under the cooperation of the retaining spring b and the first protrusion 210 in the quick-plug interface a, and the indication mark moves to the reference mark at this time. If the quality of the quick-plug interface a is unqualified, that is, the front end of the detection piece 200 is reset under the action of the elastic reset piece or is locked under the cooperation of the retaining spring b and the first limit step 220 in the quick-plug interface a, the indication mark and the reference mark are misaligned at this time. Through the above structure, the detection personnel can obtain the detection result more intuitively.
