Description

Technical Field

[0001] The utility model relates to the technical field of inspection tools, in particular to a visual rod used for observing the status of valves at high places. Background Art

[0002] At present, the height of the vent valve of the public engineering air compressor is 3m or above from the ground. The vent valve is an electric / pneumatic valve, and the start and stop operations are controlled on the air compressor operation page. According to the operating specifications, the valve status must be observed when inspecting or starting and stopping the equipment. Due to installation requirements, the valve opening mark of the vent valve is directly above. Therefore, in order to observe the valve status, it is necessary to perform a high-altitude operation. Single-person high-altitude operation is not only laborious, but also poses a safety hazard of falling. Utility Model Content

[0003] The purpose of the present invention is to provide a visual rod for observing the status of a valve at a high position, aiming to solve the problems mentioned in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: the visual rod for observing the status of high-place valves includes a rod body, a locking seat is provided at one end of the rod body, an extension rod, connecting heads are provided at both ends of the extension rod, and a mounting seat. The connecting heads at both ends of the extension rod are respectively connected to the locking seat and the mounting seat through locking members, a screw is threadedly connected to the mounting seat, an observation tube is provided on the screw, a mounting tube is provided at one end of the observation tube, a convex mirror is provided at the end of the mounting tube away from the observation tube, and a plane mirror is provided at the other end of the mounting tube, the convex mirror and the plane mirror are arranged perpendicular to each other, and a through groove is provided on the side of the mounting tube.

[0005] Preferably, the rod is retractable.

[0006] Preferably, the rod body has a gripping area, and the gripping area of ​​the rod body is provided with an anti-slip layer.

[0007] The beneficial effects of the utility model are:

[0008] The visual rod enables inspectors to observe the status of the valve accurately and efficiently while standing on the ground, avoiding high-altitude operations, improving the convenience of inspections, and reducing safety hazards. In addition, through the magnification of the convex mirror and the reflection of the plane mirror, inspectors can clearly and directly see the status of the valve, and the use effect is good.

[0013] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1-3 As shown, a visual rod for observing the status of a high valve includes a rod body 2, a locking seat 3 is provided at one end of the rod body 2, an extension rod 4, connecting heads 5 are provided at both ends of the extension rod 4, and a mounting seat 6 is also provided. The connecting heads 5 at both ends of the extension rod 4 are respectively connected to the locking seat 3 and the mounting seat 6 through locking members 7, a screw 8 is threadedly connected to the mounting seat 6, an observation tube 9 is provided on the screw 8, a mounting tube 10 is provided at one end of the observation tube 9, a convex mirror 11 is provided at the end of the mounting tube 10 away from the observation tube 9, and a plane mirror 12 is provided at the other end of the mounting tube 10, the convex mirror 11 and the plane mirror 12 are arranged perpendicular to each other, and a through groove is provided on the side of the mounting tube 10.

[0015] The locking member 7 can be a bolt assembly or a locking pin. The locking member 7 can be used to connect the connector 5 to the locking seat 3 and the connector 5 to the mounting seat 6 respectively. When the locking member 7 is not completely locked, the connector 5 and the locking seat 3, as well as the connector 5 and the mounting seat 6, can rotate around the locking member 7. Therefore, the angles of the observation tube 9 and the mounting tube 10 can be easily adjusted, and the positions of the convex mirror 11 and the plane mirror 12 can be adjusted. When observing the opening mark of the valve 1, move the device, The opening mark of the valve 1 to be observed is located between the convex mirror 11 and the plane mirror 12. The opening mark of the valve 1 enters the plane mirror 12 after being reflected by the convex mirror 11. The inspector observes the opening mark of the valve 1 displayed in the plane mirror 12 through the observation tube 9 on the ground. Since the opening mark of the valve 1 is reflected twice by the convex mirror 11 and the plane mirror 12, the picture that enters the inspector's eyes is a normal, non-mirrored picture, so the inspector can intuitively and directly see the opening status of the valve 1.

[0016] Furthermore, the rod body 2 is retractable, so that the visual rod can be stored and carried conveniently. At the same time, the rod body 2 can be extended to a suitable length according to the height of the tank body, thereby improving the convenience of use.

[0017] Furthermore, the rod body 2 has a gripping area, and an anti-slip layer 13 is provided at the gripping area of ​​the rod body 2 to avoid unstable holding when gripping the rod body 2, facilitating stable and accurate observation of the image in the plane mirror 12.

[0018] The visual rod enables the inspector to observe the status of the valve 1 accurately and efficiently while standing on the ground, avoiding high-altitude operations, improving the convenience of inspection, and reducing safety hazards. In addition, through the magnification of the convex mirror 11 and the reflection of the plane mirror 12, the inspector can clearly and directly see the status of the valve 1, and the use effect is good.

[0019] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
