Description

Technical Field

[0001] This utility model relates to the technical field of fuel system control components, and in particular to a fuel switch direction positioning mechanism. Background Technology

[0002] The fuel switch is a critical control component in the fuel system. The accuracy and reliability of its directional positioning directly affect the stability of fuel supply and the safety of system operation. In various fuel-powered devices and engine systems, the fuel switch is typically installed in the fuel tank or fuel supply line to control the on / off state or flow direction of fuel.

[0003] Traditional fuel switch directional positioning mechanisms often use a single snap-fit ​​or bolt fixing method, resulting in low positioning accuracy. Snap-fit ​​structures are prone to wear leading to increased gaps, causing the switch direction to easily shift and affecting fuel control stability. Bolt fixing requires repeated angle adjustments, which is cumbersome and makes precise positioning difficult. The assembly gap between the positioning mechanism and the fuel filler hole can easily lead to fuel leakage, especially in vibrating environments, posing a higher risk of leakage and safety hazards. Adjusting the positioning can easily damage the installation seal, or cause positioning failure due to installation position deviation, resulting in poor practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a fuel switch direction positioning mechanism that can accurately lock the direction of the fuel switch, while also having a sealing and leak-proof function to avoid the risk of fuel leakage, and is easy to operate and has strong positioning stability.

[0005] To achieve the above objectives, a fuel switch direction positioning mechanism is provided, including a housing, a mounting mechanism, and a support mechanism. The mounting mechanism includes an oil filling hole on the surface of the housing, and a bolt rod is threaded onto the inner wall of the oil filling hole. The support mechanism includes a fixing column fixedly mounted on the lower surface of the bolt rod, and a scroll plate rotatably mounted inside the fixing column. Four sliders are adapted to the lower surface of the scroll plate.

[0006] According to the fuel switch direction positioning mechanism, a first sliding groove is provided on the inner wall of the fuel injection hole, and a limit ring is fixedly provided below the fuel injection hole and fixedly provided on the inner wall of the housing.

[0007] According to the fuel switch direction positioning mechanism, a first knob is fixedly provided on the upper surface of the bolt rod, a sealing plate is fixedly provided on the lower surface of the fixing column, and a sealing ring is fixedly provided on the surface of the sealing plate.

[0008] According to the aforementioned fuel switch direction positioning mechanism, the supporting mechanism further includes a second knob rotatably disposed on the upper surface of the first knob, and a rotating shaft fixedly disposed on the lower surface of the second knob. The rotating shaft rotatably passes through the bolt rod and the fixing column, and is fixedly connected to the upper surface of the scroll plate.

[0009] According to the fuel switch direction positioning mechanism, a fixing block is fixedly provided on the lower surface of each of the four sliders, and four second sliding grooves are provided on the lower surface of the fixing post.

[0010] According to the fuel switch direction positioning mechanism, the four second slides are slidably connected to the slider and the fixed block, and the slider and the fixed block are also slidably connected to the first slide.

[0011] According to the aforementioned fuel switch direction positioning mechanism, the limiting ring is adapted to the sealing ring and the sealing plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. Compared with the existing technology, this fuel switch direction positioning mechanism independently controls the installation and positioning with a first knob and the direction locking with a second knob through dual knobs. This allows for step-by-step installation and positioning without interference from each other, ensuring accurate installation of the fixing post and avoiding damage to the sealing structure during positioning. The operation logic is also clearer.

[0014] 2. Compared with the prior art, the fuel switch directional positioning mechanism adopts a scroll plate to drive four sliders to extend and retract radially in sync. With the dual guidance of the first and second slide grooves, the sliders are subjected to uniform force and move synchronously. It can constrain the fuel switch symmetrically in the circumference, resulting in higher positioning accuracy and strong stability after locking. It is not easy to deviate in direction due to vibration. Attached Figure Description

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model provides a fuel switch direction positioning mechanism, which includes a housing 1, a mounting mechanism 2, and a support mechanism 3. The mounting mechanism 2 includes an oil injection hole 5 on the surface of the housing 1, and a bolt rod 9 is threaded on the inner wall of the oil injection hole 5. The support mechanism 3 includes a fixing column 10 fixedly mounted on the lower surface of the bolt rod 9, and a scroll plate 15 rotatably mounted inside the fixing column 10. Four sliders 16 are adapted to the lower surface of the scroll plate 15.

[0024] The inner wall of the oil injection hole 5 has a first sliding groove 4, and a limit ring 6 is fixedly installed below the oil injection hole 5 and fixedly installed on the inner wall of the housing 1. A first knob 7 is fixedly installed on the upper surface of the bolt rod 9, and a sealing plate 12 is fixedly installed on the lower surface of the fixing column 10. A sealing ring 11 is fixedly installed on the surface of the sealing plate 12.

[0025] The supporting mechanism 3 also includes a second knob 13 rotatably mounted on the upper surface of the first knob 7. A rotating shaft 14 is fixedly mounted on the lower surface of the second knob 13. The rotating shaft 14 rotatably passes through the bolt rod 9 and the fixing post 10, and is fixedly connected to the upper surface of the scroll plate 15. A fixing block 17 is fixedly mounted on the lower surface of each of the four sliders 16, and four second sliding grooves 18 are formed on the lower surface of the fixing post 10.

[0026] The first groove 4 is formed on the inner wall of the oil filling hole 5, providing a guide trajectory for the radial sliding of the slider 16 and the fixed block 17. When the slider 16 moves under the drive of the scroll plate 15, the first groove 4 restricts its sliding direction, ensuring that the slider 16 can accurately extend and retract radially along the inner wall of the oil filling hole 5, thereby achieving positioning constraint on the fuel switch direction.

[0027] When the bolt rod 9 is tightened to the position, the limiting ring 6 fits with the sealing plate 12 and the sealing ring 11 to form a sealing structure to prevent fuel leakage. By adapting to the sealing plate 12, it indirectly limits the tightening limit position of the bolt rod 9, ensuring that the fixed column 10 accurately reaches the preset working position, providing a prerequisite for the subsequent positioning of the scroll plate 15 driving the slider 16.

[0028] The scroll plate 15 is rotatably mounted inside the fixed column 10, and its lower surface has a scroll-shaped trajectory structure that is adapted to the slider 16. When it rotates, through the cooperation of the scroll trajectory and the four sliders 16, the rotational motion is converted into the radial synchronous extension and retraction motion of the sliders 16, which slide along the first slide groove 4 and the second slide groove 18, thereby achieving uniform and symmetrical positioning adjustment of the fuel switch direction.

[0029] Once the fixed post 10 is in place, the second knob 13 is rotated, operating independently of the first knob 7 without interference. This rotation, via the rotating shaft 14, drives the scroll plate 15 inside the fixed post 10 to rotate. The lower surface of the scroll plate 15 has a vortex-shaped trajectory, which is adapted to the four sliders 16. As the scroll plate 15 rotates, its trajectory pushes the sliders 16 to slide radially outward synchronously along the second groove 18 of the double-guided fixed post 10 and the first groove 4 of the fuel injection hole 5. When the sliders 16 extend outward, they contact and abut against the first groove 4. By utilizing the symmetrical distribution and synchronous movement of the four sliders 16, the rotational freedom of the switch is uniformly constrained circumferentially, ultimately achieving precise locking of the fuel switch direction.

[0030] Four second slide grooves 18 are slidably connected to sliders 16 and fixing blocks 17, which are also slidably connected to the first slide groove 4. The limiting ring 6 is adapted to the sealing ring 11 and the sealing plate 12.

[0031] Working principle: The bolt rod 9 is screwed into the housing 1 through the thread on the inner wall of the oil filling hole 5. The first knob 7 is turned to drive the bolt rod 9 and the fixing column 10 to move downwards synchronously. When the sealing plate 12 is in contact with the limiting ring 6 on the inner wall of the housing 1, the bolt rod 9 reaches the tightening limit position. At this time, the sealing ring 11 is squeezed and together with the limiting ring 6 and the sealing plate 12, a sealing structure is formed to block the fuel leakage channel.

[0032] Turning the second knob 13 causes the shaft 14 below it to pass through the bolt rod 9 and the fixing post 10, which in turn drives the scroll plate 15 inside the fixing post 10 to rotate. The scroll plate 15 has a vortex-shaped trajectory on its lower surface that matches the four sliders 16. During the rotation, the sliders 16 are pushed to slide radially outward synchronously along the second groove 18 of the fixing post 10 and the first groove 4 of the oil injection hole 5.

[0033] The slider 16 extends outward to abut against the corresponding part of the fuel switch. The four sliders 16 are symmetrically distributed to uniformly constrain the rotational freedom of the switch in the circumferential direction, thereby achieving precise locking of the fuel switch direction. If unlocking is required, the second knob 13 is rotated in the opposite direction to reset the scroll plate 15, and the sliders 16 retract radially in sync, releasing the constraint on the switch.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
