[0027] Example

[0028] Please refer to Figure 1-Figure 5 The present embodiment provides an adjustable red line marking device for a pressure gauge, comprising: a dial grabbing mechanism, the dial grabbing mechanism comprising a base 1 and a plurality of claws 2, the plurality of claws 2 being circumferentially spaced apart on the base 1; a marking mechanism 3, the marking mechanism 3 comprising a marking pointer 301 and a mounting head 302, the mounting head 302 being disposed on the marking pointer 301, a groove 13 for accommodating the mounting head 302 being provided on any claw 2, the mounting head 302 being connected to the claw 2 via a locking member 4.

[0029] In this embodiment, the dial gripping mechanism is used to fix the entire adjustable pressure gauge warning mark device on the pressure gauge by gripping the pressure gauge dial. Specifically, the base 1 is used to install a plurality of claws 2. Preferably, the number of the claws 2 is three, and the three claws 2 are evenly clamped on the outer side wall of the pressure gauge dial, so that the claws 2 work together to clamp the pressure gauge dial, which is convenient for improving the stability of the warning mark device when used.

[0030] In this embodiment, the marking mechanism 3 is used to mark the maximum operating pressure of the pressure vessel, so that the user can quickly observe whether the pressure vessel has reached the maximum operating pressure according to the pressure gauge pointer. The marking pointer 301 is positioned outside the dial of the pressure gauge to indicate the maximum working load of the pressure vessel. The mounting head 302 is used to fix the marking pointer 301 on the claw 2, so that the user can change the pressure gauge load pointed by the marking pointer 301 by rotating the base 1. The mounting head 302 is a rectangular parallelepiped structure, and the groove 13 is a rectangular parallelepiped groove structure adapted to the size of the mounting head 302. Both use a rectangular parallelepiped structure to facilitate the sliding positioning of the mounting head 302 of the marking pointer 301 when entering the groove 13. The locking member 4 is used to lock and fix the marking pointer 301 on the claw 2, which is convenient for installation and disassembly.

[0031] Please refer to Figure 1 and Figure 3In some implementations of the present embodiment, a slide groove 5 for the claw 2 to slide is opened in the above-mentioned base 1, and the claw 2 can slide back and forth along the opening direction of the slide groove 5. A driving mechanism for driving the claw 2 to slide along the slide groove 5 is provided on the base 1.

[0032] In this embodiment, the number of the above-mentioned slide grooves 5 is adapted to the number of claws 2, and the extension lines of the opening directions of the three slide grooves 5 intersect on the central axis of the base 1, which is convenient for collecting and gathering the claws 2 through the driving mechanism, thereby adapting to different pressure gauges and being suitable for pressure gauge dials of different sizes.

[0033] Please refer to Figure 1-Figure 3 In some implementations of the present embodiment, the driving mechanism includes a shell 7, a screw rod 8, a slider 9 and a connecting rod 10. A receiving groove 6 is provided on the base 1. The shell 7 is covered on the base 1. The screw rod 8 is rotatably arranged in the shell 7. The central axis of the screw rod 8 coincides with the central axis of the base 1. The slider 9 is arranged on the screw rod 8, and the screw rod 8 is threadedly connected to the slider 9. The two ends of the connecting rod 10 are respectively hinged to one end of the claw 2 located in the receiving groove 6 and the slider 9, and the end of the screw rod 8 away from the base 1 passes through the shell 7.

[0034] In this embodiment, the shell 7 is used to cooperate with the accommodating groove 6 of the base 1 to form a cavity structure for carrying the rotation of the screw rod 8. The two ends of the screw rod 8 are rotatably connected to the base 1 and the inner wall of the shell 7 respectively. The end of the screw rod 8 passing through the shell 7 is used for the user to hold it by hand, so as to facilitate the manual drive of the screw rod 8. The slider 9 is a ring-mounted structure. The slider 9 of the above-mentioned ring-mounted mechanism is sleeved on the outer wall of the screw rod 8. Due to the threaded matching connection between the screw rod 8 and the slider 9, the spiral pair of the screw rod 8 and the slider 9 is used to realize the conversion between rotational motion and linear movement. By driving the screw rod 8 to rotate, the slider 9 is driven to move linearly, thereby pulling the connecting rod 10. The movement of the connecting rod 10 drives the claw 2 connected thereto, thereby realizing the clamping and fixing of the pressure gauge dial by the claw 2.

[0035] Please refer to Figure 1 In some implementations of the present embodiment, a knob 11 is provided at one end of the screw rod 8 passing through the housing 7 , and an anti-slip layer 12 is provided on the outer wall of the knob 11 .

[0036] In this embodiment, the diameter of the knob 11 is larger than the diameter of the screw rod 8 to facilitate the grip of human hands. The anti-slip layer 12 is used to increase the friction coefficient between the human hand and the outer wall of the knob 11, thereby increasing the friction force between the human hand and the knob 11.

[0037] Please refer to Figure 1 and Figure 5In some implementations of the present embodiment, the locking member 4 includes a locking spring 401 and a limiting column 402. A positioning groove is provided on the mounting head 302. One end of the locking spring 401 is fixed to the bottom of the positioning groove. The limiting column 402 is arranged at the other end of the locking spring 401. A limiting hole is provided on the claw 2. The locking spring 401 can push the limiting column 402 into the limiting hole.

[0038] In this embodiment, the locking member 4 is used to fix the mounting head 302 on the claw 2. Specifically, the positioning groove is used for the locking spring 401 and the limiting column 402. The locking spring 401 is used to push the limiting column 402 into the limiting hole. When the center axis of the limiting hole and the center axis of the limiting column 402 coincide, the locking spring 401 continuously restores its original length, thereby pushing the limiting column 402 into the limiting hole to achieve locking and fixing of the mounting head 302.

[0039] Please refer to Figure 1 In some implementations of this embodiment, a protective layer 14 is provided at the abutment point between the above-mentioned claw 2 and the pressure gauge.

[0040] In this embodiment, the protective layer 14 is made of a flexible material. When installed, the protective layer 14 is located between the clamping claw 2 and the pressure gauge dial, thereby preventing the rigid contact between the clamping claw 2 and the pressure gauge from damaging the pressure gauge dial.

[0041] Preferably, the protective layer 14 can be made of sponge, which is a porous and elastic material whose internal structure consists of many pores and bubbles. When an object is vibrated by external force, physical deformation will occur inside the sponge, and these deformations will absorb the vibration and disperse it into the surrounding environment, thereby playing a shock-absorbing role.

[0042] When in use, turn the knob 11 so that the grasping size formed by the claw 2 is larger than the size of the pressure gauge dial to be clamped, attach the side of the base 1 away from the knob 11 to the back of the pressure gauge dial, adjust the claw 2 where the marking pointer 301 is to be installed to the warning pressure position, turn the knob 11, and the screw rod 8 rotates coaxially in the housing 7 along with the rotation of the knob 11. The slider 9 moves along the central axis of the screw rod 8 to drive the connecting rod 10 to move. The movement of the connecting rod 10 drives the claw 2 connected thereto to move closer to the central axis of the base 1. When the inner arc surface of the claw 2 abuts against the surface of the pressure gauge, stop turning the knob 11, and then push the mounting head 302 of the marking mechanism 3 into the groove 13 of the claw 2. When the central axis of the limit column 402 coincides with the central axis of the limit hole, the locking spring 401 restores its original length to push the limit column 402 into the locking hole.

[0043] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
