[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "embodiment" as used herein refers to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Reference Figures 1-4 This embodiment provides an oil storage device for a sealing test bench, comprising a frame 1 and an oil tank 2; and further comprising:

[0039] The driving mechanism 3 is disposed inside the frame 1 and is used to drive the oil tank 2 to slide relative to the frame 1. More specifically, a track 5 is fixed inside the frame 1, and a slider is fixed at the bottom of the oil tank 2 and is slidably connected to the track 5;

[0040] The support mechanism 4 is provided at the bottom of the oil tank 2 and is used to support the oil tank 2 when the oil tank 2 is staggered with the frame 1;

[0041] The driving mechanism 3 and the supporting mechanism 4 are respectively located on both sides of the oil tank 2;

[0042] like Figure 4 As shown, the driving mechanism 3 includes a driving shaft 31, a swing arm 1 32 and a swing arm 2 33;

[0043] The drive shaft 31 is rotatably connected to the frame 1. In order to improve the stability of the drive shaft 31, a bearing seat for rotatably supporting the drive shaft 31 is provided on the frame 1.

[0044] One end of the swing arm 1 32 is fixedly connected to the drive shaft 31, one end of the swing arm 2 33 is rotatably connected to the oil tank 2, and the other end of the swing arm 1 32 is rotatably connected to the other end of the swing arm 2 33, and the two form a V-shaped structure;

[0045] The operating principle of the present invention is as follows: when the drive shaft 31 rotates, it drives the swing arm 1 32 to rotate, and then drives the oil tank 2 to slide along the track 5 through the swing arm 2 33. The track 5 is fixed inside the frame 1, and a slider that cooperates with the track 5 is provided at the bottom of the oil tank 2 to ensure that the oil tank 2 can slide smoothly. When the oil tank 2 slides out of the frame 1, the support mechanism 4 starts to play a role, supporting the bottom of the oil tank 2 to prevent the oil tank 2 from tilting or becoming unstable due to gravity. By introducing the design of a slidable oil tank 2, this device increases the space for maintenance of the oil tank 2, significantly improves the maintainability of the oil tank 2, and enhances the safety of operation.

[0046] In the traditional design, the motor directly drives the drive shaft 31 to rotate to realize the sliding of the oil tank 2. However, due to the lack of a precise stroke control mechanism, this method often leads to inaccurate position problems of the oil tank 2 during the sliding process, and may even cause jamming or damage due to excessive rotation. As a preferred solution of the present invention, Figure 4 As shown, the driving mechanism 3 further includes a connecting rod 34 fixed to the end of the driving shaft 31 and a power mechanism 35 fixed in the frame 1;

[0047] The connecting rod 34 is provided with a first waist hole extending along the length direction;

[0048] A driving shaft 36 is provided at the output end of the power mechanism 1 35. The power mechanism 1 35 can be an air cylinder, an oil cylinder, or an electric telescopic rod, etc., and its purpose is to drive the driving shaft 36 to move along a straight trajectory. The driving shaft 36 extends into the first waist hole. As shown in the figure, the moving trajectory of the driving shaft 36 forms an angle with the first waist hole, so that the driving shaft 36 will not get stuck when moving.

[0049] The operating principle of the driving mechanism 3 is as follows: when the power mechanism 1 35 drives the push shaft 36 to move in the first waist hole, it will drive the connecting rod 34 to move together, and then drive the driving shaft 31 to rotate. The rotation of the driving shaft 31 is transmitted to the oil tank 2 through the swing arm 1 32 and the swing arm 2 33, causing the oil tank 2 to slide along the track 5.

[0050] In the traditional design, the output end of the power mechanism is arranged along the width direction of the frame 1, which increases the space occupied by the frame 1 and brings inconvenience to movement and use. As a preferred solution of the present invention, the output end of the power mechanism 35 moves along the height direction of the frame 1 or along the length direction of the frame 1, such as Figure 4As shown, the output end of the power mechanism 35 moves along the height direction of the frame 1, and the corresponding drive shaft 31 is arranged in the horizontal direction; similarly, if the output end of the power mechanism 35 moves along the length direction of the frame 1, the arrangement direction of the drive shaft 31 and other components should also be adjusted accordingly; the above design makes the arrangement of the power mechanism 35 more flexible, and can better adapt to different installation requirements within a limited space, effectively reducing the space occupied by the power mechanism 35, thereby making the entire equipment more compact and reasonable.

[0051] In the traditional design, when the fuel tank 2 is staggered with the frame 1, if there is no appropriate support mechanism 4, the fuel tank 2 may tilt or become unstable due to its own weight, which not only increases the safety hazard during maintenance, but may also cause damage to the fuel tank 2. As a preferred solution of the present invention, Figure 1 and Figure 3 As shown, the support mechanism 4 includes a telescopic rod 41, an adjustment plate 42, a support plate 43, an adjustment mechanism 44 and a telescopic mechanism 45;

[0052] One end of the telescopic rod 41 is connected to the bottom end of the fuel tank 2, and the other end of the telescopic rod 41 is connected to the adjustment plate 42. In order to improve the lifting stability of the adjustment plate 42, two groups of telescopic rods 41 are symmetrically arranged;

[0053] The adjustment mechanism 44 is used to connect the adjustment plate 42 and the support plate 43 and adjust the distance between them;

[0054] The telescopic mechanism 45 is used to connect the oil tank 2 and the adjustment plate 42 and adjust the distance between them;

[0055] The operating principle of the support mechanism 4 is as follows: when the oil tank 2 is staggered with the frame 1, the telescopic mechanism 45 is operated to adjust the vertical position of the adjustment plate 42 and the support plate 43. During this process, the telescopic rod 41 undergoes adaptive changes. When the stroke of the telescopic mechanism 45 is maximum, the distance between the support plate 43 and the adjustment plate 42 can also be adjusted by the adjustment mechanism 44, thereby achieving effective support.

[0056] In the traditional design, if the motor is used to directly drive the power shaft 451 to rotate to realize the lifting of the adjustment plate 42, the problem of difficult control of the stroke is often faced. As a preferred solution of the utility model, Figure 3 As shown, the telescopic mechanism 45 includes a power shaft 451 rotatably connected to the oil tank 2, a driving rod 1 452, a driving rod 2 453 and a rotating shaft 454. The power shaft 451 is rotatably connected to the oil tank 2 through a bearing seat.

[0057] One end of the first driving rod 452 is fixedly connected to the power shaft 451, one end of the second driving rod 453 is rotatably connected to the adjustment plate 42 via the rotating shaft 454, and the other end of the first driving rod 452 and the other end of the second driving rod 453 are rotatably connected via the intermediate shaft 458, and the two form a V-shaped structure;

[0058] The telescopic mechanism 45 further includes a swing rod 455 fixedly connected to the end of the power shaft 451 and a second power mechanism 456 fixedly connected to the oil tank 2. The second power mechanism 456 can be an air cylinder, an oil cylinder or an electric telescopic rod, etc.

[0059] The swing rod 455 is provided with a second waist hole extending along the length direction;

[0060] The output end of the second power mechanism 456 is fixedly connected to the guide shaft 457, which extends into the second waist hole. As shown in the figure, the moving trajectory of the guide shaft 457 is at an angle to the second waist hole to prevent the guide shaft 457 from getting stuck.

[0061] The operating principle of the telescopic mechanism 45 is as follows: when the power mechanism 2 456 is started, the guide shaft 457 will move in the second waist hole, driving the swing rod 455 and the power shaft 451 to rotate. When the power shaft 451 rotates, the V-shaped structure formed by the driving rod 1 452 and the driving rod 2 453 will change the angle accordingly, thereby driving the adjustment plate 42 and the support plate 43 to move.

[0062] In the traditional design, when the support mechanism 4 cannot self-lock, the fuel tank 2 may become unstable when sliding out and supported on the ground, especially when the ground is uneven or there is a slight vibration, the fuel tank 2 may shake or move slowly, increasing the safety risk during maintenance. As a preferred solution of the present invention, when the support plate 43 contacts the ground, the power shaft 451, the intermediate shaft 458 and the rotating shaft 454 are in the same straight line. When the support plate 43 contacts the ground, the weight of the fuel tank 2 will cause the support plate 43 to bear a vertical downward force. Since the vertical force acts directly on the support plate 43, it does not generate a torque to rotate the drive rod 1 452 or the drive rod 2 453, so self-locking is formed.

[0063] In the traditional design, if the adjustment mechanism 44 adopts a non-threaded connection method, it may cause problems such as inaccurate adjustment or slipping during the adjustment process. As a preferred solution of the present invention, Figure 3 As shown, the adjustment mechanism 44 includes two screw rods 441;

[0064] The two screw rods 441 are respectively threadedly connected to the two ends of the adjustment plate 42, and the bottom ends of the two screw rods 441 are rotatably connected to the support plate 43. When adjusting the distance between the support plate 43 and the adjustment plate 42, the two screw rods 441 are rotated at the same time. Since the screw rod 441 and the adjustment plate 42 are threadedly connected, the rotation of the screw rod 441 will drive the adjustment plate 42 to move axially along the screw rod 441.

[0065] In the conventional design, if the adjustment mechanism 44 is adjusted only by the threaded connection between the screw rod 441 and the adjustment plate 42, the adjustment accuracy may be low due to the single connection between the screw rod 441 and the adjustment plate 42. In particular, after long-term use, thread wear may cause the position of the adjustment plate 42 to be unstable. As a preferred solution of the present invention, Figure 3 As shown, the adjustment mechanism 44 also includes two nut pairs 442, each screw rod 441 is threadedly connected to a nut pair 442, and each nut pair 442 includes two nuts, which are respectively located on both sides of the adjustment plate 42. After the height of the support plate 43 is adjusted, the two nuts are screwed until they are in contact with the adjustment plate 42, which prevents the screw rod 441 from rotating, thereby enhancing the stability of the adjustment plate 42 during the adjustment process and ensuring that the fuel tank 2 can be reliably supported.

[0066] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
