[0066] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0067] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0068] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use.

[0071] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0072] Example 1

[0073] Reference Figures 1 to 3This embodiment provides a gear position controller, which includes a gear position controller cover 100 and a gear position controller base 200. The gear position controller cover 100 has a receiving cavity, and the gear position controller base 200 is located in the receiving cavity. The gear position controller cover 100 and the gear position controller base 200 are provided with coaxially arranged shaft holes, and the gear position controller base 200 can rotate relative to the gear position controller cover 100. A gear position damping structure is provided between the gear position controller cover 100 and the gear position controller base 200 to indicate that the gear position controller base 200 rotates to any damping position.

[0074] In practical use, the shaft hole is used to pass through the valve stem 410. The valve stem 410 can drive the gear positioner base 200 to rotate relative to the gear positioner cover 100. During the rotation, since there is a gear position damping structure between the gear positioner cover 100 and the gear positioner base 200, the gear positioner base 200 can be rotated to any damping position, thus realizing gear adjustment. Since this gear position controller can be used as a separate accessory, on the one hand, after being installed on the valve stem 410, the wobbling amplitude of the valve stem 410 can be reduced, improving the user experience; on the other hand, this gear position controller can be installed on existing mechanical valves. When the gear position controller fails and needs maintenance, it is not necessary to disassemble the entire air circuit for replacement, making maintenance operations more convenient, and there is no risk of air leakage after installation and removal.

[0075] For ease of explanation, the shaft hole corresponding to the gear shifter cover 100 is the first shaft hole 110, and the shaft hole corresponding to the gear shifter base 200 is the second shaft hole 210.

[0076] In this embodiment, the damping structure includes a gear position arc groove 120 and a gear position elastic mechanism. The gear positioner cover 100 and the gear positioner base 200 are provided with the gear position arc groove 120 and the gear position elastic mechanism, respectively. Multiple gear position arc grooves 120 are provided along the circumference, and the gear position elastic mechanism can be engaged or disengaged from any one of the multiple gear position arc grooves 120.

[0077] For example, the gear shifter cover 100 is provided with a gear shift arcuate groove 120, and the gear shifter base 200 is provided with a gear shift elastic mechanism; alternatively, the gear shifter cover 100 is provided with a gear shift elastic mechanism, and the gear shifter base 200 is provided with a gear shift arcuate groove 120. Furthermore, the portion of the gear shift arcuate groove 120 that contacts the gear shift elastic mechanism forms a point contact. This arrangement reduces the frictional force between the two, allowing the operator to rotate the gear shifter base 200 with less force.

[0078] The specific structure of the gear shift arc groove 120 is described below.

[0079] Reference Figures 3 to 5The gear shifter cover 100 adopts a plate structure with one end open and circumferentially closed, which is opposite to the first shaft hole 110; multiple gear shift arc surface grooves 120 are continuously arranged along the inner circumference of the gear shifter cover 100, and each gear shift arc surface groove 120 is radially recessed along the inner circumference of the gear shifter cover 100.

[0080] Please continue to refer to Figure 5 The multiple gear position arc grooves 120 have a starting gear position arc groove and an ending gear position arc groove; the inner circumference of the gear position cover 100 is provided with a smooth arc section 130 between the starting gear position arc groove and the ending gear position arc groove, where the gear position is zero.

[0081] In simple terms, when the gear shift elastic mechanism is engaged in any one of the multiple gear shift arc grooves 120, it indicates that the gear shift controller has a control function for a certain gear. When the gear shift elastic mechanism slides along the smooth arc section 130, it indicates that the gear shift controller has no control function, that is, it indicates that the gear is in the zero position.

[0082] The structure of the gear shift arc groove 120 has been described in detail above. Next, the structure of the gear shift elastic mechanism will be described in detail.

[0083] The gear shifting elastic mechanism includes an elastic element 310 and a ball 320. The elastic element 310 is disposed on the gear shifter base 200, and the ball 320 is rotatably confined within the gear shifter base 200. The ball 320 can abut against the elastic element 310 and the gear shifting arc groove 120 respectively. The elastic deformation direction of the elastic element 310 includes at least the radial direction along the rotation trajectory of the gear shifter base 200. This arrangement allows the elastic element to be compressed and undergo elastic deformation, so that the ball 320 can be engaged or disengaged from the gear shifting arc groove 120.

[0084] Furthermore, refer to Figure 6 and Figure 7 The gear shift base 200 includes a base body 220 and a boss protruding from one side of the base body 220. The base body 220 and the boss have a through hole arranged coaxially to form a corresponding second shaft hole 210. The elastic element 310 and the ball 320 are both provided on the boss. One side of the elastic element 310 is provided with space for it to move when it elastically deforms, and the other side is in close contact with the ball 320. The spherical surface of the ball 320 protrudes from the outer boss surface of the boss.

[0085] In this embodiment, the boss includes a first boss 230 and a second boss 240 disposed on the outer periphery of the first boss 230, and an annular space is formed between the first boss 230 and the second boss 240; the first boss 230 is provided with a second shaft hole 210, and the first boss 230 is fitted with the shaft hole corresponding to the gear shift cover 100 with a clearance 10; the elastic element 310 is engaged in the annular space; the second boss 240 is provided with a notch 241 communicating with the annular space, and the ball 320 is limited in the notch 241 and protrudes from the notch 241 out of the outer boss surface of the second boss 240.

[0086] Reference Figure 7 In the initial or unused state, the ball 320 abuts against the elastic element 310 and the inner peripheral wall of the gear shift cover 100. During the counterclockwise rotation of the ball 320, when it reaches the uppermost gear shift arc groove 120, it will compress the elastic element 310 so that the ball 320 can be engaged in the gear shift arc groove 120. After being engaged in the gear shift arc groove 120, the elastic element 310 returns to its original position. Similarly, as the ball 320 continues to rotate, it will compress the elastic element 310 so that the ball 320 can be engaged in the next gear shift arc groove 120, and so on.

[0087] Reference Figure 8 A gap 10 is left between the inner circumference of the gear shift cover 100 and the outer circumference of the gear shift base 200 (specifically the outer circumference of the second boss 240) to ensure that the gear shift base 200 can rotate relative to the gear shift cover 100.

[0088] The presence of gap 10 makes the gear shift base 200 rotate more smoothly, and the point contact between the ball 320 and the elastic element 310 makes the ball 320 roll more smoothly into the gear shift arc groove 120 of the gear shift cover 100 when the gear shift base 200 rotates, thereby generating a gear shift feel.

[0089] Based on the above embodiments, referring to Figure 3 and Figure 4 The edge of the opening of the gear shift cover 100 is provided with a flange 140 in the radial direction; the flange 140 is provided with an elastic buckle 150 for securing the gear shift cover 100 to the part to be installed.

[0090] Furthermore, the elastic buckle 150 is configured in at least two sets, the elastic buckle 150 has a snap-fit ​​portion, and a snap-fit ​​groove is formed between the snap-fit ​​portion and the flange 140; the end of the elastic buckle 150 away from the snap-fit ​​portion extends outward to form an elastic handle 160, and pressing the elastic handle 160 is used to open or retract the elastic buckle 150.

[0091] During installation, the elastic handle 160 can be squeezed by hand to open the elastic buckle 150, making it easier to fasten the gear shift cover 100 onto the part to be installed, and also easier to disassemble.

[0092] Example 2

[0093] Reference Figures 9 to 12 This second embodiment also provides a gear position controller, which differs from the first embodiment in that:

[0094] The gear shifting mechanism includes an elastic ball facet 330, which protrudes from the outer periphery of the gear shifter base 200 and can abut against the gear shifting arc groove 120.

[0095] Specifically, the gear shift elastic mechanism and the gear shift base 200 are integrally injection molded; the gear shift base 200 includes a base body 220 and a first boss 230 and a second boss 240 that both protrude from one side of the base body 220, and an annular space is formed between the first boss 230 and the second boss 240; a through hole corresponding to the boss is opened in the first boss 230, and the first boss 230 is fitted with the shaft hole 10 corresponding to the gear shift cover 100; the second boss 240 is provided with a notch 241 that communicates with the annular space, and the elastic spherical part 330 of the gear shift elastic mechanism protrudes from the notch 241.

[0096] During use, the elastic ball surface 330 of the gear shift elastic mechanism undergoes elastic deformation under pressure, so that the gear shift elastic mechanism can be engaged or disengaged from the gear shift arc groove 120.

[0097] Example 3

[0098] Reference Figures 1 to 12 This embodiment three provides a gas plug valve, which includes a valve body 400, a valve core 500, and a gear controller as described in the previous embodiment one or two. The valve body 400 includes a valve stem 410 and a valve cover 420. The valve core 500 is installed inside the valve body 400, and the valve stem 410 is connected to the valve core 500 and can drive the valve core 500 to rotate relative to the valve body 400. The valve stem 410 passes through the shaft hole and is fixed relative to the gear base 200. The gear cover 100 is installed on the valve cover 420.

[0099] The gear shifter base 200 is fixedly sleeved on the valve stem 410 through the second shaft hole 210. The diameter of the first shaft hole 110 is larger than the diameter of the second shaft hole 210, and the first shaft hole 110 is clearance-fitted with the first boss 230 of the gear shifter base 200.

[0100] In this embodiment, the gear shifter cover 100 is secured to the valve cover 420 by a spring clip 150. Furthermore, since the gear shifter is mounted above the valve cover 420, maintenance is also convenient.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
