Description

Technical Field

[0001] This utility model relates to a tooling for installing a breather valve, specifically an auxiliary device for installing a snap-on breather valve. Background Technology

[0002] In modern production assembly lines, the installation of the vent valve in the electronic control assembly is a crucial step in ensuring product performance. Currently, the common method for installing vent valves is by manually pressing them into place. The snap-fit ​​structure of the vent valve requires resistance to external force during installation. This method relies heavily on manual operation, lacking clear positioning guides. Operators judge the installation position visually, lacking precise positioning methods. Because this installation method depends on the operator's experience and visual judgment, it is difficult to ensure the vent valve is accurately positioned, often resulting in misalignment or tilting during installation. Such misaligned or tilted vent valves are prone to detachment later, causing water ingress damage to the electronic control assembly and requiring rework and reinstallation. This directly impacts production line efficiency and assembly quality. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide an installation auxiliary device for a snap-on vent valve that improves the accuracy of the vent valve during the installation process, avoids installation misalignment or misalignment, can be installed in place in one go, and improves production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An installation auxiliary device for a snap-fit ​​vent valve includes a positioning sleeve. The cross-sectional shape of the positioning sleeve is consistent with the cross-sectional shape of the countersunk hole at the installation location of the vent valve, and it can slide along the centerline of the countersunk hole. A positioning slide is slidably fitted into the inner hole of the positioning sleeve along the centerline of the positioning sleeve. A positioning insertion hole is recessed on the end face of the positioning slide facing the opening of the positioning sleeve, and is arranged along the same centerline as the positioning sleeve. The positioning insertion hole is used to insert the head of the vent valve to be installed. When the positioning slide moves towards the bottom of the positioning sleeve, the positioning slide and the vent valve to be installed, which is embedded on the positioning slide, can be accommodated in the inner hole of the positioning sleeve. A push rod is fixedly connected to the end face of the positioning slide facing the bottom of the positioning sleeve. A push rod through hole is provided at the bottom of the positioning sleeve, which allows the push rod to extend out of the positioning sleeve. The end of the push rod away from the positioning slide passes through the push rod through hole and extends out of the positioning sleeve.

[0006] In this invention, during use, the head of the snap-on vent valve is first embedded in the positioning mounting hole and abuts against the bottom of the positioning mounting hole; then, the push rod is pulled outward so that both the vent valve and the positioning slide are accommodated in the inner hole of the positioning sleeve; then, the cylindrical end of the positioning sleeve faces the countersunk hole where the vent valve is to be installed and is inserted into the countersunk hole, so that the cylindrical end of the positioning sleeve abuts against the bottom of the countersunk hole, thereby positioning the positioning sleeve; then, the push rod is pushed inward so that the positioning slide moves outward, pushing the vent valve outward; during the outward pushing of the vent valve, the snap-on end of the vent valve will correspondingly snap into the mounting hole at the bottom of the countersunk hole; because of the sliding limit of the positioning sleeve in the countersunk hole and the sliding limit of the positioning slide in the inner hole of the positioning sleeve, the vent valve will be sent into the corresponding mounting hole under the guidance of the positioning sleeve and the positioning slide, so that the vent valve will not be skewed or misaligned during the installation process, thus improving the installation quality and efficiency.

[0007] As an optimization, the push rod through hole extends along the center line of the positioning sleeve, and the push rod can slide in conjunction with the push rod through hole along the center line of the push rod through hole. This allows the operator to push the push rod more easily.

[0008] As an optimization, the positioning slide has a recessed connecting screw hole on one end face facing the bottom of the positioning sleeve, along the center line of the positioning sleeve. The end of the push rod located inside the inner hole of the positioning sleeve has a protruding connecting stud along its center line. The push rod is threaded into the connecting screw hole via the connecting stud, thus fixing the push rod to the positioning slide. This facilitates the installation and disassembly of the push rod.

[0009] As an optimization, the end of the push rod away from the positioning slide block protrudes along the center line of the push rod to form a handle. The handle is located outside the positioning sleeve, and its diameter is larger than that of the push rod. When the limiting slide block moves towards the opening of the positioning sleeve, the end face of the handle facing the push rod can abut against the bottom of the positioning sleeve, thus limiting the installation of the vent valve to be installed on the positioning slide block. By limiting the sliding movement distance of the handle end face against the bottom of the positioning sleeve, the pushing distance of the vent valve is limited. This avoids insufficient pressure during installation, resulting in incomplete installation, or excessive pressure, causing damage to the vent valve. By controlling the distance between the handle and the positioning slide block, the appropriate installation position of the vent valve is controlled, improving the installation quality of the vent valve.

[0010] As an optimization, the handle body, at one end located on the side of the push rod, has a protruding retaining ring that circumferentially surrounds the handle. When the operator grips the handle and pushes it, the retaining ring abuts against the front end of the hand gripping the handle, facilitating the pushing of the handle.

[0011] As an optimization, the end of the handle away from the push rod is provided with a circular push plate aligned with the center line of the handle. A mounting stud, aligned with the center line of the circular push plate, protrudes from the side of the circular push plate facing the handle. A mounting screw hole, aligned with the center line of the handle, is recessed on the end face of the handle facing the circular push plate. The circular push plate is threaded into the mounting screw hole via the mounting stud, thus fixing the circular push plate to the handle. The movement of the handle allows for not only gripping and pushing forward but also pressing on the end of the handle. The circular push plate increases the contact area between the handle and the operator's palm, facilitating operation.

[0012] As an optimization, a cushioning pad is adhesively bonded to the side of the circular push plate facing away from the handle. This protects the palm of the hand during continuous pressing.

[0013] Compared to existing technologies, this invention solves the problem of valve misalignment or displacement in traditional manual installation methods by introducing a positioning sleeve and a positioning slide during the vent valve installation process, significantly improving installation accuracy and reliability. Utilizing the guiding effect of the positioning sleeve and positioning slide, the vent valve can be precisely installed in place, avoiding reliance on operator experience and visual judgment, thus reducing rework caused by improper installation and lowering repair costs. Simultaneously, this solution is simple to operate, improves production efficiency, and ensures long-term product performance, especially valuable for applications requiring waterproofing and dustproofing in electrical control equipment. This technical solution effectively improves the installation quality of the vent valve, reduces electrical control system failures caused by improper installation, and has good market prospects and application promotion value.
