Description

Technical Field

[0001] This utility model belongs to the technical field of idle speed shut-off valve assembly, specifically, it relates to a quick-clamping structure for an idle speed shut-off valve assembly. Background Technology

[0002] In the installation and application of idle speed shut-off valve assemblies, traditional connection methods have significant drawbacks. Early methods often used conventional means such as bolt connections, which, while achieving fixation, resulted in cumbersome installation and disassembly processes. Taking the shut-off valve assembly in an automotive engine's idle speed control system as an example, maintenance or replacement requires the use of tools to tighten each bolt individually. This is not only time-consuming but also prone to increasing operational difficulty and reducing maintenance efficiency due to limited operating space (such as densely packed components in the engine compartment).

[0003] Furthermore, bolted connections are susceptible to loosening due to vibration after prolonged use, leading to displacement and detachment of the shut-off valve assembly, threatening stable equipment operation and vehicle performance. Simultaneously, complex connection structures increase labor time and costs in the production and assembly process, hindering efficient production and maintenance in industries such as automotive. Therefore, the industry urgently needs a quick-connect structure that is easy to operate, provides a stable connection, and can adapt to compact installation environments to optimize the assembly and maintenance process of idle shut-off valve assemblies, improve equipment reliability, and enhance production and maintenance efficiency. This quick-connect structure for idle shut-off valve assemblies was developed based on this background, aiming to solve the pain points of traditional connection methods. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a quick-clamping structure for an idle speed shut-off valve assembly that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a quick-connect structure for an idle speed shut-off valve assembly, including a shut-off valve assembly, and further including: a mounting base disposed on the shut-off valve assembly, a snap-connect mechanism rotatably connected to the mounting base, the snap-connect mechanism including a main shaft, a limit block fixedly connected to the main shaft, a snap-connect block fixedly connected to the top of the main shaft, a connecting shaft rotatably connected to the top of the main shaft, a central shaft rotatably connected to the connecting shaft, a snap-connect shaft rotatably connected to the central shaft, and a handle rotatably connected to the central shaft, the handle having a locking hole.

[0006] Furthermore, the shut-off valve assembly has a slot that corresponds to the locking block.

[0007] Furthermore, a connecting seat is fixedly connected to the mounting base, and a rotating shaft hole is provided on the connecting seat. The snap-fit ​​shaft passes through the central shaft and the rotating shaft hole and slides on the inner wall of the rotating shaft hole.

[0008] Furthermore, the handles are symmetrically arranged on the mounting base, and a locking hole is provided on one of the handles, with a locking mechanism connected through the locking hole.

[0009] Furthermore, the locking mechanism includes a latch that extends through and connects to the handle.

[0010] Furthermore, a movable shaft is rotatably connected to the buckle, a movable block is slidably connected to the movable shaft, and a retaining ring is fixedly connected to the movable block. The inner diameter of the retaining ring is larger than the diameter of the handle.

[0011] Furthermore, after alignment is completed, the operator rotates the handle, which rotates around the central axis. Through the rotational connection between the central axis and the connecting shaft, the connecting shaft is driven to move, thereby causing the main shaft to rotate around its own axis. As the main shaft rotates, the locking block fixed on it rotates synchronously, gradually locking into the slot of the shut-off valve assembly. During this process, the limiting block fixed on the main shaft plays a role. When the locking block is fully locked into the slot, the limiting block contacts the corresponding part of the mounting base, limiting the excessive rotation of the main shaft and achieving the initial locking between the shut-off valve assembly and the locking mechanism. At the same time, the locking shaft passes through the central shaft and slides on the inner wall of the rotating shaft hole of the mounting base connecting base, cooperating with the rotation of the main shaft to adapt to the positional changes of each component during the locking process, ensuring that the locking action is completed smoothly.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0013] 1. This utility model allows the locking block to be engaged into the slot by rotating the handle, and then quickly locked in place with the locking mechanism. No complicated tools or cumbersome steps are required. Assembly can be easily completed in confined spaces (such as engine compartments), greatly reducing installation and maintenance time and improving work efficiency.

[0014] 2. The locking block and the slot work together mechanically, the limit block restricts the excessive rotation of the main shaft, and the locking mechanism uses the retaining ring to constrain the handle. The multiple structures work together to effectively prevent the components from shifting or falling off due to vibration, ensuring the stable operation of the idle speed shut-off valve assembly and improving the reliability of the equipment.

[0015] 3. The snap-fit ​​shaft slides within the rotating shaft hole, and all shaft systems are rotatably connected, allowing the structure to adapt to changes in position during the snap-fit ​​process. This enables it to flexibly cope with different installation scenarios and working conditions, enhancing its applicability to complex environments.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] Example: Refer to Figures 1-4 A quick-connect structure for an idle speed shut-off valve assembly includes a shut-off valve assembly 1 and a mounting base 2 disposed on the shut-off valve assembly 1. A snap-connect mechanism 3 is rotatably connected to the mounting base 2. The snap-connect mechanism 3 includes a main shaft 31, a limit block 32 fixedly connected to the main shaft 31, a snap-connect block 33 fixedly connected to the top of the main shaft 31, a connecting shaft 34 rotatably connected to the top of the main shaft 31, a central shaft 35 rotatably connected to the connecting shaft 34, a snap-connect shaft 36 rotatably connected to the central shaft 35, and a handle 37 rotatably connected to the central shaft 35. A locking hole 38 is provided on the handle 37.

[0025] The shut-off valve assembly 1 has a slot 11, which corresponds to the snap-fit ​​block 33.

[0026] A connecting seat 21 is fixedly connected to the mounting base 2. A rotating shaft hole 22 is provided on the connecting seat 21. The snap-fit ​​shaft 36 passes through the central shaft 35 and the rotating shaft hole 22 and slides on the inner wall of the rotating shaft hole 22.

[0027] The handles 37 are symmetrically arranged on the mounting base 2, and a locking hole 38 is provided on a set of handles 37, and a locking mechanism 4 is connected through the locking hole 38.

[0028] The locking mechanism 4 includes a latch 41, which is connected through the handle 37.

[0029] A movable shaft 42 is rotatably connected to the buckle 41, a movable block 43 is slidably connected to the movable shaft 42, and a retaining ring 44 is fixedly connected to the movable block 43. The inner diameter of the retaining ring 44 is larger than the diameter of the handle 37.

[0030] After alignment is completed, the operator rotates handle 37, which rotates around the central shaft 35. Through the rotational connection between the central shaft 35 and the connecting shaft 34, the connecting shaft 34 is driven to move, thereby causing the main shaft 31 to rotate around its own axis. As the main shaft 31 rotates, the locking block 33 fixed on it rotates synchronously and gradually engages into the locking groove 11 of the shut-off valve assembly 1. During this process, the limiting block 32 fixed on the main shaft 31 plays a role. When the locking block 33 is fully engaged in the locking groove 11, the limiting block 32 contacts the corresponding part of the mounting base 2, limiting the excessive rotation of the main shaft 31 and realizing the initial engagement between the shut-off valve assembly 1 and the locking mechanism 3. At the same time, the locking shaft 36 passes through the central shaft 35 and slides on the inner wall of the rotating shaft hole 22 of the connecting seat 21 of the mounting base 2. It cooperates with the rotation of the main shaft 31 to adapt to the positional changes of each component during the engagement process, ensuring that the engagement action is completed smoothly.

[0031] In this utility model, the quick-connect structure of the idle speed shut-off valve assembly 1 uses the shut-off valve assembly 1 as a basic component, with the mounting base 2 fixedly mounted on it, providing installation and movement support for the snap-fit ​​mechanism 3. The main shaft 31 of the snap-fit ​​mechanism 3 is rotatably connected to the mounting base 2. Initially, the spatial position of the snap-fit ​​block 33 can be flexibly adjusted by operating the handle 37 and by using the linkage relationship of components such as the central shaft 35 and the connecting shaft 34, so that the snap-fit ​​block 33 is aligned with the slot 11 opened on the shut-off valve assembly 1, in preparation for the subsequent snap-fit ​​action.

[0032] After alignment is completed, the operator rotates handle 37, which rotates around the central shaft 35. Through the rotational connection between the central shaft 35 and the connecting shaft 34, the connecting shaft 34 is driven to move, thereby causing the main shaft 31 to rotate around its own axis. As the main shaft 31 rotates, the locking block 33 fixed on it rotates synchronously and gradually engages into the locking groove 11 of the shut-off valve assembly 1. During this process, the limiting block 32 fixed on the main shaft 31 plays a role. When the locking block 33 is fully engaged in the locking groove 11, the limiting block 32 contacts the corresponding part of the mounting base 2, limiting the excessive rotation of the main shaft 31 and realizing the initial engagement between the shut-off valve assembly 1 and the locking mechanism 3. At the same time, the locking shaft 36 passes through the central shaft 35 and slides on the inner wall of the rotating shaft hole 22 of the connecting seat 21 of the mounting base 2. It cooperates with the rotation of the main shaft 31 to adapt to the positional changes of each component during the engagement process, ensuring that the engagement action is completed smoothly.

[0033] After the snap-fit ​​action is completed, in order to ensure the stability of the snap-fit ​​structure, the locking mechanism 4 is used for locking. Since the handles 37 are symmetrically arranged on the mounting base 2, and a set of handles 37 have locking holes 38, the buckle 41 of the locking mechanism 4 passes through the locking hole 38. The movable shaft 42 rotatably connected to the buckle 41 can rotate relative to the buckle 41. The movable block 43 slidably connected to the movable shaft 42 can move along the movable shaft 42. When the buckle 41 passes through the locking hole 38, the movable block 43 is moved so that the retaining ring 44 fixed on the movable block 43 fits the handle 37. Since the inner diameter of the retaining ring 44 is larger than the diameter of the handle 37, the retaining ring 44 can restrict the handle 37 from rotating around the central axis 35, thereby locking the position of the snap-fit ​​mechanism 3 and preventing the snap-fit ​​block 33 from coming out of the slot 11, ensuring that the idle speed shut-off valve assembly 1 is snapped firmly and stably, and completing the entire quick snap-fit ​​and fixing process.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
