Description

Technical Field

[0001] The utility model relates to the technical field of automobile pipeline maintenance equipment, in particular to an automobile pipeline smoke leakage detection device. Background Art

[0002] At present, smoke leak detectors are usually used to locate and detect gas or liquid leaks in pipe systems. Smoke leak detectors generate smoke and introduce it into the pipe system. They determine whether there is a leak in the system by observing whether the smoke is discharged from the holes or cracks in the system. However, during the use of some smoke leak detectors, the detachable hook on the top is often hung on a fixed point in the engine compartment or other parts of the vehicle to facilitate leak detection. However, the hook on the top of the smoke leak detector can only be used for hanging and cannot provide additional hand-held support. When the leak detector needs to be moved, only the top hook is very inconvenient and takes up space. At the same time, there is a risk of loss of the hook component during disassembly and reinstallation. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] It should be noted that the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0023] like Figure 1-3 As shown, the utility model proposes an automobile pipeline smoke leak detection device, including a smoke leak detector 1, and also includes: a handle 2, installed on the top of the smoke leak detector 1; a strip groove 21 and a circular groove 22 opened on the handle 2, the strip groove 21 and the circular groove 22 are connected and the bottoms are located at the same horizontal height, and a foldable hook mechanism is provided inside the strip groove 21 and the circular groove 22; a switch mechanism is installed on the handle 2 to limit the unfolding of the folded hook mechanism; and a rebound mechanism is arranged on the inner bottom wall of the strip groove 21 to push the hook mechanism to automatically pop out.

[0024] Furthermore, the hook mechanism includes a rotating seat 23 fixedly connected to the inner bottom wall of the strip groove 21. The rotating seat 23 is located at the center of the top of the smoke leak detector 1, and its function is to make the smoke leak detector 1 at the bottom of the handle 2 stable and balanced when hung. The top of the rotating seat 23 is rotatably connected to a secondary rotating rod 24, and the end of the secondary rotating rod 24 away from the rotating seat 23 is rotatably connected to a supporting rotating piece 26, and the end of the supporting rotating piece 26 away from the secondary rotating rod 24 is rotatably connected to a main rotating rod 25, and the end of the main rotating rod 25 away from the main rotating rod 25 is fixedly connected to a hook 27.

[0025] The switch mechanism includes a telescopic groove 3 provided in the handle 2 and connected to the bar groove 21. An L-shaped card plate 32 is slidably connected inside the telescopic groove 3. A convex block 33 is provided at the top of the L-shaped card plate 32, which is automatically retracted into the telescopic groove 3 after being pressed by the main rotating rod 25. The function of the convex block 33 is to allow the folded main rotating rod 25 to pass through the convex block 33 by pressing hard into the bar groove 21 after being inserted into the bar groove 21, and finally be stuck by the convex block 33. A reset spring 31 is fixedly connected inside the telescopic groove 3 to push the L-shaped card plate 32 out of the telescopic groove 3. The function of the reset spring 31 is that when the button push rod 34 is not pressed, the L-shaped card plate 32 will automatically clamp the main rotating rod 25 through the elastic thrust of the reset spring 31. A button push rod 34 is slidably connected to the handle 2. One end of the button push rod 34 is movably passed through the bar groove 21 and is fixedly connected to the bottom of the L-shaped card plate 32.

[0026] Furthermore, the rebound mechanism includes a push spring 4 fixedly connected to the inner bottom wall of the strip groove 21. The function of the push spring 4 is to make the main rotating rod 25 on the hook mechanism automatically pop out of the strip groove 21 through the elastic thrust of the push spring 4 when the hook mechanism is not stuck by the protrusion 33, and to be used by the user. The top of the push spring 4 is fixedly connected with a push block 41 that supports the main rotating rod 25. The top of the push block 41 is provided with an arc-shaped clamping groove 42 that tightly clamps the main rotating rod 25. The function of the arc-shaped clamping groove 42 is to clamp the main rotating rod 25 through the arc-shaped clamping groove 42 at the top of the push block 41 when the main rotating rod 25 is stuck in the strip groove 21, so that the main rotating rod 25 can slide stably in the strip groove 21.

[0027] In this embodiment, it is necessary to use an automobile pipeline smoke leak detection device, such as Figure 1 As shown, the smoke detector 1 can be moved by hand through the handle 2. When the smoke detector 1 needs to be hung on a fixed point in the engine compartment of the vehicle or other parts using the hook mechanism, it is only necessary to press the button lever 34 in the direction of the handle 2, and one end of the button lever 34 presses against the L-shaped clamping plate 32 to retract into the telescopic groove 3, and the top of the L-shaped clamping plate 32 cannot clamp the main rotating rod 25 in the strip groove 21. At this time, the push block 41 is subjected to the elastic thrust of the push spring 4 at its bottom, so that the arc-shaped clamping groove 42 on the push block 41 supports the main rotating rod 25 and pops out of the strip groove 21. Finally, through the support rotating piece 26 at one end of the main rotating rod 25 and the rotating seat 23 at one end of the secondary rotating rod 24, the hook mechanism can be fully unfolded, and the hook 27 at one end of the main rotating rod 25 can also be hung on a fixed point in the engine compartment of the vehicle or other parts, which is convenient and easy to operate. When the handle 2 is needed but the hook mechanism is not used, the above operation can be reversed, and no further description is given here. The hook mechanism can be stored in the handle 2 without hindering the use of the handle 2.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
