Description

Technical Field

[0001] This utility model relates to the field of fixed caliper technology, specifically a convenient fixed caliper. Background Technology

[0002] With the booming development of the global economy, the shipping industry is thriving. As an important carrier of international trade, the safety of ships has become the focus of attention for governments and relevant agencies around the world. The ship gangway is the connection between the ship and the dock and the only passage for personnel to board and disembark. The gangway has always been a weak link in ship supervision, and it is easy for personnel to board the ship (land) without permission. The strictness and effectiveness of its supervision are directly related to the port safety level and the efficiency of border inspection and control.

[0003] Portable monitoring equipment, such as the Ladder Sentinel product, needs to be temporarily fixed to the gangway handrail. The existing fixing method is a fixed threaded clamp method, which is bulky and cumbersome to operate. When using it, you need to first tighten many turns of the thread to widen the grip, and then tighten many more turns of the thread to clamp it, which is time-consuming and labor-intensive. At the same time, 90° adjustment requires disassembly and reinstallation, which is quite inconvenient.

[0004] Therefore, we propose a convenient fixing caliper to solve the above problems. Utility Model Content

[0005] To address the technical problem that existing fixing methods require tightening many turns of the thread to widen the grip and then tightening many more turns of the thread to clamp the clamp, which is time-consuming and labor-intensive, this utility model provides a convenient fixing clamp.

[0006] This utility model is achieved using the following technical solution: a convenient fixed caliper, including an upper caliper jaw and a lower caliper jaw, wherein the lower caliper jaw is located directly below the upper caliper jaw, a connecting plate is fixedly connected to the top of the upper caliper jaw, a damping shaft is fixedly connected to one side of the connecting plate, a track rod is fixedly connected to the bottom of the connecting plate, a sliding rod is movably connected to the outside of the track rod, an adjusting screw is rotatably connected to the bottom of the lower caliper jaw, and one end of the sliding rod is threadedly connected to one end of the adjusting screw.

[0007] Preferably, one end of the caliper jaw is fixedly connected to a limiting pin, and one end of the limiting pin is movably connected to the inside of the track rod.

[0008] Preferably, a limiting groove is machined on one side of the track rod, and one end of the limiting pin is movably connected inside the limiting groove.

[0009] Preferably, the bottom of the track rod is fixedly connected to a limit bolt, and the slide rod is located above the limit bolt.

[0010] Preferably, the upper jaw and lower jaw of the caliper have an arc-shaped profile.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In use, this utility model first moves the sliding rod downward to open the lower jaw of the caliper, then places the upper jaw of the caliper on the gangway handrail. The sliding rod is then slid upward to move the lower jaw of the caliper closer to the gangway handrail. Then, the adjusting screw is rotated, which causes one end of the sliding rod to move upward, changing the perpendicularity between the sliding rod and the track rod. During this process, the sliding rod automatically locks in its current position by lever principle and friction between the sliding rod and the track rod. The adjusting screw then causes the lower jaw of the caliper to tighten further, clamping the gangway handrail together with the upper jaw of the caliper, thus achieving a stable fixation of the portable intelligent monitoring device on the gangway. In use, this utility model allows for quick and convenient movement by directly sliding the slide bar on the track bar, minimizing the distance required for threaded fastening. The arc-shaped upper and lower jaw teeth of the caliper are adapted to different specifications of gangway handrails. In use, this utility model can achieve rotational positioning at any angle on the plane by rotating and adjusting the damping shaft, and can achieve damping positioning at any angle, ensuring that the equipment can maintain a stable monitoring posture on the handrails in different directions, and adapting to the complex handrail layout scenarios of gangways.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0015] Example 1: Please refer to Figure 1 - Figure 2This embodiment of a convenient fixed caliper includes an upper caliper jaw 1 and a lower caliper jaw 2. The lower caliper jaw 2 is located directly below the upper caliper jaw 1. A connecting plate 3 is fixedly connected to the top of the upper caliper jaw 1. A damping shaft 4 is fixedly connected to one side of the connecting plate 3. A track rod 5 is fixedly connected to the bottom of the connecting plate 3. A sliding rod 7 is movably connected to the outside of the track rod 5. An adjusting screw 6 is rotatably connected to the bottom of the lower caliper jaw 2. One end of the sliding rod 7 is threadedly connected to one end of the adjusting screw 6. One end of the damping shaft 4 is fixedly connected to the housing of a portable intelligent monitoring device. The upper caliper jaw 1 and the lower caliper jaw 2 have an arc-shaped profile. In this invention, the caliper is installed on the casing of the portable intelligent monitoring device. During use, the slide bar 7 is first moved downwards to open the lower jaw 2 of the caliper, and the upper jaw 1 of the caliper is placed on the gangway handrail. The slide bar 7 is then slid upwards, causing the lower jaw 2 to move upwards and close to the gangway handrail. Then, the adjusting screw 6 is rotated, causing one end of the slide bar 7 to move upwards, changing the perpendicularity between the slide bar 7 and the track bar 5. During this process, thanks to the lever principle and the friction between the slide bar 7 and the track bar 5, the slide bar 7 automatically locks in its current position. The adjusting screw 6 then causes the lower jaw 2 to tighten further, clamping the gangway handrail together with the upper jaw 1, ultimately achieving a stable fixation of the portable intelligent monitoring device on the gangway. By directly sliding the slide bar 7 on the track bar 5, quick and convenient movement is achieved, minimizing the distance required for threaded tightening. The curved jaw teeth of the upper and lower jaws of the caliper adapt to different specifications of gangway handrails. Secondly, when the fixing method needs to switch from the horizontal handrail to the vertical handrail by 90°, the damping shaft 4 can be rotated and adjusted. The damping shaft is an existing technology that can achieve rotation and positioning at any angle on the plane and can achieve damping positioning at any angle, ensuring that the equipment can maintain a stable monitoring posture on the handrail in different directions, and adapting to the complex handrail layout scenarios of the gangway. Furthermore, one end of the caliper jaw 2 is fixedly connected to a limiting pin 8, and one end of the limiting pin 8 is movably connected to the inside of the track rod 5. A limiting groove 9 is machined on one side of the track rod 5, and one end of the limiting pin 8 is movably connected to the inside of the limiting groove 9. When the caliper jaw 2 moves, the caliper jaw 2 will drive the limiting pin 8 to move, and the limiting pin 8 will move along the inside of the limiting groove 9. The limiting groove 9 will limit the movement of the limiting pin 8, thereby keeping the caliper jaw 2 in a stable state when it moves. Furthermore, the bottom of the track rod 5 is fixedly connected to a limiting bolt 10, and the slide rod 7 is located above the limiting bolt 10. By setting the limiting bolt 10, the limiting bolt 10 will limit the movement of the slide rod 7 and prevent the slide rod 7 from leaving the outside of the track rod 5.

[0016] Working principle: In use, first move the slide bar 7 downward to open the lower jaw 2 of the caliper, place the upper jaw 1 of the caliper on the gangway handrail, slide the slide bar 7 upward to move the lower jaw 2 of the caliper up close to the gangway handrail, and then rotate the adjusting screw 6. The adjusting screw 6 will drive one end of the slide bar 7 to move upward, changing the perpendicularity between the slide bar 7 and the track bar 5. During this process, with the help of the lever principle and the friction between the slide bar 7 and the track bar 5, the slide bar 7 will automatically lock in the current position. Then, the adjusting screw 6 will drive the lower jaw 2 of the caliper to tighten further, and together with the upper jaw 1, clamp the gangway handrail, thus achieving a stable fixation of the portable intelligent monitoring equipment on the gangway.

[0017] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
