DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that when the hole cover of the existing foot-operated oil measuring hole is wrapped around the upper end of the oil measuring tube, the pedal connecting rod used for stepping on will continue to protrude, and the continuous protrusion will make the device easily catch nearby moving objects during daily use, which is easy to cause the pedal connecting rod to loosen, this embodiment provides the following technical solutions:

[0022] A pedal-type oil measuring hole for a petrochemical storage tank with folding and anti-bulging function, comprising an oil measuring tube 1, a hole cover 9 is arranged at the upper end of the outer portion of the oil measuring tube 1, as shown in FIG. Figure 1 As shown, the oil measuring tube 1 is wrapped by the hole cover 9 at the upper end of the outer surface of the oil measuring tube 1 to prevent external foreign matter from entering the inner part through the oil measuring tube 1 and contacting the oil, thereby preventing the oil from being contaminated. A connecting rod 3 is welded at the middle position of the upper end of the hole cover 9, and the connecting rod 3 is welded and fixed to the upper end of the hole cover 9. A main bracket 2 is arranged at one end of the outer surface of the connecting rod 3, and the main bracket 2 and the connecting rod 3 are rotatably connected through a first connecting shaft 6. The lower end of the main bracket 2 is welded and fixed to the upper end of the oil measuring tube 1. The connecting rod 3 is supported and transmitted by the main bracket 2, so that one end of the connecting rod 3 can drive the hole cover 9 to rotate around the first connecting shaft 6 as the center of the circle and unfold to expose the oil measuring tube 1 after being subjected to pressure.

[0023] In this embodiment, a tray 4 is provided on one side of the connecting rod 3. A support surface 8 is provided on one side of the upper end of the tray 4. A stepping piece 12 for stepping on is provided at the upper end of the connecting rod 3. A secondary bracket 5 for connection and transmission is provided at the upper end of the tray 4. The secondary bracket 5 and the stepping piece 12 are rotatably connected by a second connecting shaft 7. As Figure 2 and Figure 3 shown, when it is necessary to step on and make the connecting rod 3 drive the hole cover 9 to rotate and flip, the stepping piece 12 can be stretched out by rotating around the second connecting shaft 7. After being stretched out, it is supported by the tray 4, and the support makes the stepping piece 12 fit the upper end of the support surface 8. The tray 4 holds up the unfolded stepping piece 12, which is convenient for the hole cover 9 connected to the stepping piece 12 to tilt up after being stepped on;

[0024] In this embodiment, a connecting ring 11 is provided at the other end outside the connecting rod 3, and the connecting ring 11 is fixedly welded to the connecting rod 3. As Figure 4 shown, a connecting column 10 is provided at the lower end of the connecting ring 11, and the lower end of the connecting column 10 is fixedly welded to the upper end of the oil measuring pipe 1. A threaded rod 16 is penetrated through the inside of the connecting ring 11, and the threaded rod 16 penetrates through the connecting ring 11 and extends into the inside of the connecting column 10. By penetrating the connecting ring 11 with the threaded rod 16 and embedding it into the inside of the connecting column 10, the stepping piece 12 and the hole cover 9 can be fixed, improving the stability during the sealing process of the hole cover 9;

[0025] In this embodiment, the outside of the threaded rod 16 is in threaded fit with the inside of both the connecting ring 11 and the connecting column 10. As Figure 5 shown, the rotation of the threaded rod 16 can directly penetrate through the connecting ring 11 and embed into the inside of the connecting column 10. Through the threaded fit, the sealing of the hole cover 9 can be further fixed, improving the wrapping effect of the hole cover 9 on the oil measuring pipe 1;

[0026] In this embodiment, a rotating handle 15 is welded at the center position of the upper end of the threaded rod 16. As Figure 1 and Figure 5 shown, the rotation of the threaded rod 16 can be facilitated by the rotation handle 15 fixed by welding, facilitating the adjustment of the sealing state of the hole cover 9;

[0027] In this embodiment, a wrapping frame 13 is provided at one end of the stepping piece 12. The surface of the wrapping frame 13 facing the rotating handle 15 is connected to the outer card slot of the rotating handle 15. As Figure 1 shown, during the rotation and storage of the stepping piece 12, the wrapping frame 13 will wrap around the upper end of the outside of the rotating handle 15. While protecting the rotating handle 15 by wrapping, it avoids the loosening of the connection state between the hole cover 9 and the oil measuring pipe 1 caused by accidental touch of the rotating handle 15, improving the sealing effect of the oil measuring pipe 1;

[0028] In this embodiment, a recessed cavity 14 is provided on the side of the wrapping frame 13 away from the rotary handle 15. As Figure 1 and Figure 4 shown, the recessed recessed cavity 14 facilitates the user to manually lift and adjust the deployment and storage states of the pedal 12.

[0029] Working principle: When using the oil measuring hole and opening the hole cover 9, the pedal 12 rotates around the second connecting shaft 7 under the support of the auxiliary bracket 5. The pedal 12 rotates and fits against the support surface 8 at the upper end of the tray 4. Rotate the rotary handle 15. The rotation of the rotary handle 15 drives the threaded rod 16 to rotate within the connecting column 10. As the threaded rod 16 rotates, it moves outside the connecting column 10. The tray 4 lifts the pedal 12. Step on the pedal 12. The pedal 12 drives the connecting rod 3 connected to the tray 4 to rotate under the support of the tray 4, so that the connecting rod 3 rotates around the first connecting shaft 6 under the support of the main bracket 2. The connecting rod 3 can directly drive the hole cover 9 to rotate and expose the upper end of the oil measuring pipe 1.
