Description

Technical Field

[0001] This invention relates to the field of lubrication technology, and in particular to a slider, an oil injection gun, and an oil-injectable slider assembly. Background Technology

[0002] For disinfection cabinets with external sliding rails, there are usually sliders and shelf guide rods to support the shelves inside the cavity. The sliders are usually made of plastic and are fixed to the sheet metal shelves by slider fixing seats. The guide rods are fixed on both sides of the inner cavity, and the sliders can move horizontally on the guide rods to realize the horizontal pulling of the shelves.

[0003] Since the slider and the guide rod are in contact friction, lubricating grease is usually applied to the surface of the guide rod or the bottom of the slide rail to ensure smooth pulling. However, as the usage time increases, the lubricating grease will gradually wear down and decrease, resulting in a continuous decrease in the smoothness of the shelf pulling. Summary of the Invention

[0004] The purpose of this invention is to provide a slider, an oil injection gun, and an oil-injectable slider assembly to alleviate the technical problem that the smoothness of the slider in the existing pull-out structure decreases with increasing use time.

[0005] In a first aspect, the present invention provides a slider comprising: an oil reservoir and a roller, wherein an annular first groove is provided on the circumferential sidewall of the roller, and the bottom surface of the first groove is used to connect with a guide rod.

[0006] The roller is rotatably connected to the bottom of the oil storage section;

[0007] The oil storage section is provided with an oil inlet, an oil outlet, and an oil storage cavity connecting the oil inlet and the oil outlet. The oil outlet faces the bottom surface of the first groove and forms an oil seal gap with it.

[0008] Furthermore, the bottom surface of the first groove is provided with a second annular groove with a width smaller than that of the first groove;

[0009] The oil outlet is directly opposite the opening of the second groove.

[0010] Furthermore, the slider also includes a cover, which is movably connected to the oil storage section to open and close the oil inlet.

[0011] Furthermore, a reset member is provided between the cover and the oil storage part, the reset member being used to make the cover tend to close the oil inlet.

[0012] Secondly, the present invention provides an oil injection gun, which is used to inject oil into the oil inlet of the aforementioned slider.

[0013] Furthermore, the oil gun includes a housing, a trigger, an oil nozzle, an oil pipe, and an oil tank;

[0014] The oil injection nozzle is connected to the outer casing;

[0015] One end of the oil pipe extends into the interior of the oil pipe, and the other end is connected to the oil injection nozzle;

[0016] The oil tank is installed inside the outer shell; a pressing mechanism is provided on the oil tank, which is used to squeeze the oil tank;

[0017] The trigger is movably connected to the housing and is also connected to the pressing mechanism, so that after the trigger is fired, the oil tank outputs lubricating oil to the oil pipe.

[0018] Furthermore, the outer casing is provided with a positioning groove, which is positioned in conjunction with the top of the slider so that the oil injection nozzle faces the oil inlet.

[0019] Furthermore, the oil gun also includes a push rod and a connecting rod. The push rod is slidably connected to the housing along a first direction. One end of the connecting rod is rotatably connected to the tail end of the push rod, and the other end is rotatably connected to the trigger.

[0020] The push rod is used to push the cover on the slider to open the oil inlet.

[0021] Furthermore, the tail end of the oil nozzle is connected to the oil pipe, and the head end of the oil nozzle is provided with an oil spray port.

[0022] The outer casing is provided with a sliding groove extending in a first direction, and the oil injection nozzle is provided with a third fixed post that is slidably connected to the sliding groove, and the oil injection nozzle can swing about the third fixed post relative to the sliding groove in the up and down direction.

[0023] The push rod includes a guide ramp located below the oil nozzle, in a first direction and from the trigger toward the oil nozzle, the guide ramp being inclined downwards;

[0024] The push rod includes a apex angle located above the oil nozzle, and the apex angle includes a plane and a vertical surface arranged at an angle;

[0025] When the trigger is in the unfired state, the included angle formed by the bottom surface and the rear side surface of the grease nipple abuts against the guide slope; the top surface of the grease nipple is parallel to the plane; there is a moving space between the third fixing post and the slide groove;

[0026] When the trigger is in the firing state, the bottom surface of the oil nozzle is parallel to the guide slope; in the first direction, and from the trigger toward the oil nozzle, the oil nozzle is tilted downwards, and the oil injection port is toward the oil inlet.

[0027] Thirdly, the present invention provides an oil-fillable slider assembly, including the aforementioned slider and the aforementioned oil-filling gun.

[0028] The present invention has at least the following advantages or beneficial effects:

[0029] The slider provided by the present invention includes: an oil storage part and a roller. The roller has an annular first groove on its circumferential sidewall, and the bottom surface of the first groove is used to connect with a guide rod. The roller is rotatably connected to the bottom of the oil storage part. The oil storage part is provided with an oil inlet, an oil outlet, and an oil storage cavity connected between the oil inlet and the oil outlet. The oil outlet faces the bottom surface of the first groove and forms an oil seal gap with it.

[0030] The slider can slide along the guide rod. When there is sufficient lubricating oil on the bottom surface of the first groove, the roller and the guide rod experience sliding friction, meaning the roller is stationary relative to the oil reservoir. There is some lubricating oil between the oil outlet and the first groove, but due to the close proximity, the lubricating oil between them blocks the oil outlet, preventing further lubricating oil flow. As time increases, when the lubricating oil between the roller and the guide rod becomes insufficient, the roller and the oil reservoir experience rolling friction. The lubricating oil below the oil outlet moves away from its original position as the roller rotates, leaving no lubricating oil below the outlet. The lubricating oil in the oil reservoir flows downwards to the bottom surface of the first groove under gravity. The coefficient of friction between the roller and the guide rod decreases, returning to sliding friction, and the oil outlet is blocked again by the subsequently flowing lubricating oil. Furthermore, after the lubricating oil in the oil reservoir is completely consumed, it can be replenished through the oil inlet. This ensures that the push-pull mechanism with this slider always maintains smooth operation. Attached Figure Description

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0051] 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.

[0052] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0053] 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. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0054] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0055] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] like Figure 1 - Figure 3 As shown, the slider 1 provided by the present invention can be installed on the shelf and cooperate with the guide rod in the cavity of the cooking device to realize the pull-out of the shelf.

[0057] like Figure 2 As shown, the slider 1 includes an oil reservoir and a roller 14. A first annular groove 141 is provided on the circumferential sidewall of the roller 14, and the bottom surface of the first groove 141 is used to connect with the guide rod. The width of the first groove 141 is approximately the same as the diameter of the guide rod, reducing the swaying amplitude during shelf movement.

[0058] like Figure 3 As shown, the roller 14 is rotatably connected to the bottom of the oil storage unit. The oil storage unit is provided with an oil inlet, an oil outlet 15, and an oil storage cavity 11 connecting the oil inlet and the oil outlet 15. The oil storage cavity 11 stores lubricating oil. The oil inlet is located directly above the oil storage cavity 11, and the oil outlet 15 is located directly below the oil storage cavity 11. The oil outlet 15 faces the bottom surface of the first groove 141 and forms an oil seal gap with it. The length of the oil seal gap, that is, the vertical distance between the oil outlet 15 and the bottom surface of the first groove 141, is related to the viscosity of the lubricating oil. The higher the viscosity, the greater the distance. That is to say, when the oil storage unit and the roller 14 are relatively stationary, the lubricating oil located between the oil outlet 15 and the first groove 141 will not flow to both sides or flows very little, and the lubricating oil in the oil storage cavity 11 will no longer flow out from the oil outlet 15.

[0059] The slider 1 can slide along the guide rod. When there is sufficient lubricating oil on the bottom surface of the first groove 141, the roller 14 and the guide rod experience sliding friction, meaning the roller 14 is stationary relative to the oil reservoir. There is some lubricating oil between the oil outlet 15 and the first groove 141, but due to the close proximity, the lubricating oil blocks the oil outlet 15, preventing further lubricating oil flow. As time increases, if the lubricating oil between the roller 14 and the guide rod becomes insufficient, the roller 14 and the oil reservoir will experience rolling friction. The lubricating oil below the oil outlet 15 will move away from its original position as the roller 14 rotates, leaving no lubricating oil below the outlet 15. The lubricating oil in the oil reservoir 11 will flow downwards to the bottom surface of the first groove 141 under gravity. The coefficient of friction between the roller 14 and the guide rod will decrease, returning to sliding friction, and the oil outlet 15 will be blocked again by the subsequently flowing lubricating oil. Furthermore, after the lubricating oil in the oil reservoir 11 is completely consumed, it can be replenished through the oil inlet. This ensures that the push-pull mechanism with slider 1 in this solution always maintains smooth push-pull operation.

[0060] like Figure 2 As shown, the bottom surface of the first groove 141 is provided with a second annular groove 142 with a width smaller than that of the first groove 141; the oil outlet 15 is directly opposite the opening of the second groove 142.

[0061] The second groove 142 can temporarily store lubricating oil. That is, the lubricating oil flowing out of the oil outlet 15 first enters the second groove 142. The lubricating oil in the second groove 142 can slowly flow downward and contact the guide rod, thereby extending the rotation cycle of the roller 14.

[0062] The slider 1 also includes a cover 13, which is movably connected to the oil storage part to open and close the oil inlet. When the slider 1 is in normal use, the cover 13 is in the closed state to prevent impurities from entering the oil storage chamber 11. The cover 13 and the oil storage part can be connected by sliding or rotating.

[0063] like Figure 2 As shown, a reset member 12, such as a reset spring, can be provided between the cover 13 and the oil storage part. The reset member 12 is used to make the cover 13 tend to close the oil inlet. That is, the user can actively open the cover 13. When the external force applied to the cover 13 is removed, the reset member 12 drives the cover 13 to close the oil inlet.

[0064] The slider 1 may also include a fixed base 2 and a snap fastener 3. One side of the fixed base 2 has a connecting post 21 perpendicular to the fixed base 2. The end of the connecting base away from the fixed base 2 has a slot 22. The oil storage section has a mounting through hole. After the connecting post 21 passes through the through hole of the oil storage section, the slot 22 connects with the snap fastener 3, thus connecting the fixed base 2 to the oil storage section. The fixed base 2 has mounting holes; by passing screws through the mounting holes, the slider 1 can be fixed to the shelf.

[0065] like Figure 4 - Figure 16 As shown, the oil gun provided by this invention is used to inject oil into the oil inlet of the slider 1. Because the space where the slider 1 is located is narrow, a dedicated oil gun can be used to replenish the lubricating oil in the slider 1.

[0066] like Figure 4 and Figure 5 As shown, the oil gun includes a housing 4, a trigger 5, an oil nozzle 6, an oil pipe 7, and an oil tank 8; the oil nozzle 6 is connected to the housing 4; one end of the oil pipe 7 extends into the interior of the oil pipe 7, and the other end is connected to the oil nozzle 6; the oil tank 8 is installed inside the housing 4; a pressing mechanism is provided on the oil tank 8, which is used to squeeze the oil tank 8; the trigger 5 is movably connected to the housing 4, and the trigger 5 is connected to the pressing mechanism, so that after the trigger 5 is fired, the oil tank 8 outputs lubricating oil to the oil pipe 7.

[0067] The outer casing 4 can be gun-shaped, with a handle structure 41. An oil tank 8 is disposed inside the handle structure 41, and a trigger 5 is disposed near the handle structure 41. When the user presses the trigger 5, the trigger 5 rotates and drives the pressing mechanism, and the lubricating oil in the oil tank 8 is sprayed out from the oil nozzle 6 through the oil pipe 7.

[0068] like Figure 6 - Figure 8 As shown, specifically, the oil tank 8 includes an oil storage chamber 81 and a piston 82. The piston 82 is sealed to the oil storage chamber 81. An oil pipe 7 is placed in the middle of the piston 82. The piston 82 can move up and down along the oil storage chamber 81, and the internal lubricating grease is squeezed out from the oil pipe 7 by the air pressure difference.

[0069] The pressing mechanism includes an oil tank connecting rod 83. One end of the oil tank connecting rod 83 is provided with a first fixing post 831, which is installed at both ends of the top outer shell 4 of the oil tank 8, allowing the oil tank connecting rod 83 to rotate around the first fixing post 831. The other end of the oil tank connecting rod 83 is provided with a second fixing post 832, which is installed in a track in the cavity of the trigger 5, allowing the oil tank connecting rod 83 to move by the rotation of the trigger 5.

[0070] The oil tank connecting rod 83 is also provided with a hollow structure 833 to avoid the piston 82, and guide posts 834 are provided on both sides. The guide posts 834 are connected to the guide groove 821 provided on the top of the piston 82. Through the guide structure, the piston 82 of the oil tank 8 can be moved up and down by the movement of the oil tank connecting rod 83.

[0071] A trigger spring 51 can also be provided between the trigger 5 and the housing 4. One end of the trigger spring 51 is connected to the housing 4 and the other end is connected to the trigger 5, so that the trigger 5 can be reset after being pressed.

[0072] The outer casing 4 is provided with a positioning groove 42, which is positioned in conjunction with the top of the slider 1 so that the oil nozzle 6 faces the oil inlet.

[0073] Because the location of slider 1 is narrow, the field of vision is limited when adding lubricating oil. The positioning groove 42 can be used to find the position of slider 1. When the positioning groove 42 is just on the top of slider 1, the positioning can be clearly felt. At this time, the oil can be added without observation.

[0074] The oil gun also includes a push rod 61 and a connecting rod 52. The push rod 61 is slidably connected to the housing 4 in a first direction. One end of the connecting rod 52 is rotatably connected to the tail end of the push rod 61, and the other end is rotatably connected to the trigger 5. The push rod 61 is used to push the cover 13 on the slider 1 to open the oil inlet.

[0075] like Figure 9 - Figure 12 As shown, in this embodiment, the slider 1 has a slidable cover 13. After the outer shell 4 and the slider 1 are positioned using the positioning groove 42, the trigger 5 can be pressed. The trigger 5 drives the push rod 61 to move in the first direction, thereby opening the cover 13 and exposing the oil inlet. To increase the stability of opening the cover 13, a protruding protrusion can be provided on the cover 13, so that the push rod 61 contacts the protrusion to complete the opening of the cover 13.

[0076] The tail end of the oil nozzle 6 is connected to the oil pipe 7, and the head end of the oil nozzle 6 is provided with an oil spray port; the outer shell 4 is provided with a sliding groove 431 extending along a first direction, and the oil nozzle 6 is provided with a third fixing post 63 slidably connected to the sliding groove 431, and the oil nozzle 6 can swing around the third fixing post 63 relative to the sliding groove 431 in a vertical direction; the push rod 61 includes a guide slope 611 located below the oil nozzle 6, in the first direction, and in the direction from the trigger 5 toward the oil nozzle 6, the guide slope 611 is inclined downward; the push rod 61 includes a guide slope 611 located below the oil nozzle 6, in the first direction, and in the direction from the trigger 5 toward the oil nozzle 6, the guide slope 611 is inclined downward; The apex 613 above the nozzle 6 includes a plane and a vertical surface arranged at an angle; when the trigger 5 is in the unfired state, the angle formed by the bottom surface and the rear side surface of the nozzle 6 abuts against the guide slope 611; the top surface of the nozzle 6 is parallel to the plane; there is a moving space between the third fixing post 63 and the slide groove 431; when the trigger 5 is in the fired state, the bottom surface of the nozzle 6 is parallel to the guide slope 611; in a first direction, and from the trigger 5 toward the nozzle 6, the nozzle 6 is tilted downwards, and the oil nozzle is facing the oil inlet.

[0077] The tail end of the oil nozzle 6 is connected to the oil pipe 7, and the head end is provided with an oil spray port. The oil pipe 7 passes through the inside of the push rod 61, which can push open the cover 13. The oil nozzle 6 has a third fixing post 63 on both sides, and the outer shell 4 has two fixing blocks 43 located on both sides of the oil nozzle 6. Each fixing block 43 has a sliding groove 431. The third fixing post 63 is assembled with the sliding groove 431, so that the oil nozzle 6 can move and rotate along the sliding groove 431. The guide slope 611 is provided below the oil nozzle 6, which can tilt the oil nozzle 6 at a certain angle. The push rod 61 can also have a limiting surface 612, which abuts against the head end face of the oil nozzle 6. In cooperation with the guide slope 611, the oil nozzle 6 can be fixed horizontally. The apex angle 613 on the push rod 61 cooperates with the guide slope 611 to fix the oil nozzle 6 at an angle.

[0078] like Figure 13 - Figure 16As shown, the specific oil injection process is as follows: First, align the positioning groove 42 on the outer shell 4 with the slider 1. After the top of the slider 1 is completely placed into the positioning groove 42, the cover 13 contacts the push rod 61. When the trigger 5 is pressed, the trigger 5 drives the connecting rod 52, pushing the push rod 61 forward. The oil injection nozzle 6 is fixed parallel to the oil outlet push rod under the action of the guide slope 611 and moves forward together with the push rod 61. The oil injection nozzle 6 moves horizontally forward along the slide groove 431. When the oil injection nozzle 6 moves horizontally to the limit of the slide groove 431, it stops moving forward. At this time, the push rod 61 still moves forward. The guide slope 611 pushes the oil injection nozzle 6 to tilt, so that the third fixed column 63 rotates around the slide groove 431 at a certain angle until the bottom surface of the oil injection nozzle 6 is parallel to the guide slope 611. At this time, the push rod 61 pushes the cover 13 open, and the oil injection nozzle 6 extends into the oil inlet to inject oil, avoiding the lubricating oil from spilling on the outside. When the trigger 5 is retracted, the push rod 61 moves backward, and the top corner 613 abuts against the top surface of the oil nozzle 6, causing the third fixing post 63 to rotate around the slide groove 431 to a horizontal position. When the limiting surface 612 is in contact with the end face of the oil nozzle 6, the push rod 61 drives the oil nozzle 6 to move backward to the limiting position.

[0079] The oil-fillable slider 1 assembly provided by the present invention includes the slider 1 and the oil-filling gun described above.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions 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.
