The sliders are generally plastic structures and are fixed to the sheet metal shelves through slider fixing seats. The guide rods are fixed on both sides of the inner cavity. The sliders can move horizontally on the guide rods to achieve horizontal pulling of the shelves.

[0003] Since the slider and the guide rod are in contact and friction, lubricating grease is generally 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 decrease, resulting in a continuous decrease in the smoothness of pulling out the shelves. Summary of the invention

[0004] The object of the present invention is to provide a slider, a grease gun and an oil-fillable slider assembly, so as to alleviate the technical problem that the smoothness of the slider of the existing pull-out structure is continuously reduced with the increase of the use time.

[0005] In a first aspect, the present invention provides a slider, comprising: an oil storage portion and a roller, wherein a first annular groove is provided on a circumferential side wall of the roller, and a 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 portion;

[0007] The oil storage portion 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 therewith.

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

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

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

[0011] Furthermore, a reset member is provided between the cover body and the oil storage portion, and the reset member is used to make the cover body have a tendency to close the oil inlet.

[0012] In a second aspect, the present invention provides a grease gun, which is used to inject oil into the oil inlet of the above-mentioned sliding block.

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

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

[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 housing; a pressing mechanism is provided on the oil tank, and the pressing mechanism is used to squeeze the oil tank;

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

[0018] Furthermore, a positioning groove is provided on the housing, and the positioning groove cooperates with the top of the sliding block for positioning so that the oil injection nozzle faces the oil inlet.

[0019] Furthermore, the grease gun further comprises a push rod and a connecting rod, wherein the push rod is slidably connected to the housing along a first direction, one end of the connecting rod is rotationally connected to the tail end of the push rod, and the other end is rotationally connected to the trigger;

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

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

[0022] The housing is provided with a slide groove extending in a first direction, the oiling nozzle is provided with a third fixing column slidably connected to the slide groove, and the oiling nozzle can swing around the third fixing column relative to the slide groove in an up-and-down direction;

[0023] The ejector rod comprises a guide slope located below the oiling nozzle, and in a first direction and from the trigger toward the oiling nozzle, the guide slope is inclined downward;

[0024] The ejector rod comprises a vertex angle located above the oiling nozzle, and the vertex angle comprises a plane and a vertical surface arranged at an angle;

[0025] When the trigger is in an unfired state, the angle formed by the bottom surface and the rear side surface of the oiling nozzle abuts against the guiding inclined surface; the top surface of the oiling nozzle is parallel to the plane; and there is a moving space between the third fixing column and the sliding groove;

[0026] When the trigger is in a firing state, the bottom surface of the oiling nozzle is parallel to the guiding slope; in a first direction, and from the trigger toward the oiling nozzle, the oiling nozzle is inclined downward, and the oil injection port faces the oil inlet.

[0027] In a third aspect, the present invention provides an oil-fillable slider assembly, comprising the above-mentioned slider and the above-mentioned 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, wherein a first annular groove is arranged on the circumferential side wall of the roller, and the bottom surface of the first groove is used to be connected with the guide rod; the roller is rotatably connected with 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, and the oil outlet faces the bottom surface of the first groove and forms an oil seal gap therewith.

[0030] The slider can slide along the guide rod. When the bottom surface of the first groove is covered with sufficient lubricating oil, the roller and the guide rod are in sliding friction, that is, the roller is stationary relative to the oil storage part, and there is a part of lubricating oil between the oil outlet and the first groove. However, due to the close distance between the two, the lubricating oil between the two blocks the oil outlet, and no lubricating oil flows out of the oil outlet. When the lubricating oil between the roller and the guide rod is insufficient as time goes by, rolling friction will occur between the roller and the oil storage part, and the lubricating oil below the oil outlet will leave its original position as the roller rotates. There is no lubricating oil below the oil outlet, and the lubricating oil in the oil storage chamber flows downward to the bottom surface of the first groove under the action of gravity. The friction coefficient between the roller and the guide rod is reduced, and it returns to sliding friction again, and the oil outlet is blocked again by the subsequent lubricating oil flowing out. Moreover, after the lubricating oil in the oil storage chamber is completely consumed, it can also be replenished through the oil inlet. Thereby ensuring that the push-pull mechanism with the slider of this scheme always maintains the smoothness of push-pull. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] 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, further definition and explanation thereof is not required in subsequent drawings.

[0053] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0054] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only 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 the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to 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 pulling and drawing of the shelf.

[0057] like Figure 2 As shown, the slider 1 includes an oil storage portion and a roller 14, and a first annular groove 141 is provided on the circumferential side wall 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 similar to the diameter of the guide rod, which reduces the shaking amplitude when the shelf moves.

[0058] like Figure 3 As shown, the roller 14 is rotatably connected to the bottom of the oil storage part. The oil storage part is provided with an oil inlet, an oil outlet 15 and an oil storage chamber 11 connected between the oil inlet and the oil outlet 15. Lubricating oil is stored in the oil storage chamber 11. The oil inlet is located directly above the oil storage chamber 11, and the oil outlet 15 is located directly below the oil storage chamber 11. The oil outlet 15 faces the bottom surface of the first groove 141 and forms an oil seal gap therewith, wherein the length of the oil seal gap, i.e., the distance between the oil outlet 15 and the bottom surface of the first groove 141 in the vertical direction, 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 part and the roller 14 are relatively stationary, the lubricating oil between the oil outlet 15 and the first groove 141 will not or rarely flow to both sides, and the lubricating oil in the oil storage chamber 11 will no longer flow out from the oil outlet 15.

[0059] The slider 1 can slide along the guide rod. When the bottom surface of the first groove 141 is covered with sufficient lubricating oil, the roller 14 and the guide rod are in sliding friction, that is, the roller 14 is stationary relative to the oil storage part, and there is a part of lubricating oil between the oil outlet 15 and the first groove 141. However, since the distance between the two is very close, the lubricating oil between the two blocks the oil outlet 15, and no lubricating oil flows out of the oil outlet 15. When the lubricating oil between the roller 14 and the guide rod is insufficient as time goes by, rolling friction will occur between the roller 14 and the oil storage part, and the lubricating oil below the oil outlet 15 will leave the original position as the roller 14 rotates. There is no lubricating oil below the oil outlet 15. The lubricating oil in the oil storage chamber 11 flows downward to the bottom surface of the first groove 141 under the action of gravity, and the friction coefficient between the roller 14 and the guide rod is reduced, and it returns to sliding friction again. The oil outlet 15 is blocked again by the subsequent lubricating oil flowing out. In addition, after the lubricating oil in the oil storage chamber 11 is completely consumed, it can also be replenished through the oil inlet. This ensures that the push-pull mechanism with the slider 1 of the present solution always maintains smooth pushing and pulling.

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

[0061] Lubricating oil can be temporarily pre-stored in the second groove 142 , that is, the lubricating oil flowing out of the oil outlet 15 first enters the second groove 142 , and the lubricating oil in the second groove 142 can slowly flow downward and contact the guide rod, thereby extending the rotation period of the roller 14 .

[0062] The slider 1 also includes a cover body 13, which is movably connected to the oil storage part to open and close the oil inlet. When the slider 1 is normally used, the cover body 13 is in a closed state to prevent impurities from entering the oil storage chamber 11; the cover body 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, may be provided between the cover body 13 and the oil storage portion. The reset member 12 is used to make the cover body 13 have a tendency to close the oil inlet, that is, the user can actively open the cover body 13, and when the external force applied to the cover body 13 is removed, the reset member 12 drives the cover body 13 to close the oil inlet.

[0064] The slider 1 may also include a fixing seat 2 and a buckle 3. A connecting column 21 is provided on one side of the fixing seat 2. The connecting column 21 is perpendicular to the fixing seat 2. A clamping groove 22 is provided on one end of the connecting seat away from the fixing seat 2. A mounting through hole is provided on the oil storage part. After the connecting column 21 passes through the through hole of the oil storage part, the clamping groove 22 is connected to the buckle 3 to connect the fixing seat 2 to the oil storage part. The fixing seat 2 is provided with a mounting hole. The slider 1 can be fixed on the shelf by passing a screw through the mounting hole.

[0065] like Figure 4 - Fig.16 As shown, the grease gun provided by the present invention is used to inject oil into the oil inlet of the above-mentioned slider 1. Since the slider 1 is located in a narrow space, a special grease gun can be used to replenish the lubricating oil to the slider 1.

[0066] like Figure 4 and Figure 5 As shown, the grease gun includes a housing 4, a trigger 5, a grease nozzle 6, an oil pipe 7 and an oil tank 8; the grease 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 grease nozzle 6; the oil tank 8 is installed in the housing 4; a pressing mechanism is provided on the oil tank 8, and the pressing mechanism 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 housing 4 may be gun-shaped and have a handle structure 41, the oil tank 8 is disposed in the handle structure 41, and the trigger 5 is disposed near the handle structure 41. After 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 filling nozzle 6 through the oil pipe 7.

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

[0069] The pressing mechanism includes an oil tank connecting rod 83, one end of which is provided with a first fixing column 831, which is mounted to both ends of the top shell 4 of the oil tank 8, so that the oil tank connecting rod 83 can rotate around the first fixing column 831. The other end of the oil tank connecting rod 83 is provided with a second fixing column 832, which is mounted in the track at the cavity of the trigger 5, so that the oil tank connecting rod 83 can move through the rotation of the trigger 5.

[0070] The oil tank connecting rod 83 is also provided with a hollow structure 833 for avoiding the piston 82, and guide columns 834 are provided on both sides. The guide columns 834 are connected to the guide grooves 821 provided on the top of the piston 82. The movement of the oil tank connecting rod 83 can be used through the guide structure to make the oil tank 8 piston 82 move up and down.

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

[0072] The housing 4 is provided with a positioning groove 42 , and the positioning groove 42 cooperates with the top of the slider 1 to position the oil injection nozzle 6 toward the oil inlet.

[0073] Since the position of the 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 the slider 1. When the positioning groove 42 is just buckled on the top of the slider 1, it can be clearly felt that the positioning is completed. At this time, the oiling can be completed without observation.

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

[0075] like Fig. 9 - Fig.12 As shown, in this embodiment, the slider 1 has a slidable cover 13. After the housing 4 and the slider 1 are positioned by the positioning groove 42, the trigger 5 can be pressed, and the trigger 5 drives the push rod 61 to move along the first direction, thereby pushing the cover 13 open to expose the oil inlet. In order to increase the stability of the cover 13 when opening, 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 oiling nozzle 6 is connected to the oil pipe 7, and the head end of the oiling nozzle 6 is provided with an oil injection port; the housing 4 is provided with a slide groove 431 extending in a first direction, and the oiling nozzle 6 is provided with a third fixed column 63 slidably connected with the slide groove 431, and the oiling nozzle 6 can swing around the third fixed column 63 relative to the slide groove 431 in the up and down directions; the push rod 61 includes a guide inclined surface 611 located below the oiling nozzle 6, and in the first direction, and in the direction from the trigger 5 to the oiling nozzle 6, the guide inclined surface 611 is inclined downward ... The top angle 613 above the nozzle 6 includes a plane and a vertical plane set at an angle; when the trigger 5 is in an unfired state, the angle formed by the bottom surface and the rear side surface of the oiling nozzle 6 abuts against the guide inclined surface 611; the top surface of the oiling nozzle 6 is parallel to the plane; there is a moving space between the third fixed column 63 and the slide groove 431; when the trigger 5 is in a fired state, the bottom surface of the oiling nozzle 6 is parallel to the guide inclined surface 611; in a first direction, and from the trigger 5 toward the oiling nozzle 6, the oiling nozzle 6 is tilted downward, and the oil spray port is toward the oil inlet.

[0077] The tail end of the oiling nozzle 6 is connected to the oil pipe 7, and the head end is provided with an oil injection port. The oil pipe 7 passes through the inside of the push rod 61, and the push rod 61 can push open the cover body 13. Third fixing columns 63 are provided on both sides of the oiling nozzle 6, and two fixing blocks 43 located on both sides of the oiling nozzle 6 are provided on the shell 4. Each fixing block 43 is provided with a slide groove 431. The third fixing column 63 is assembled with the slide groove 431, so that the oiling nozzle 6 can move and rotate along the slide groove 431. The guide slope 611 is arranged below the oiling nozzle 6, and the oiling nozzle 6 can be tilted at a certain angle. The push rod 61 can also be provided with a limiting surface 612, which abuts against the end surface of the head end of the oiling nozzle 6, and cooperates with the guide slope 611 to fix the oiling nozzle 6 horizontally. The top angle 613 on the push rod 61 cooperates with the guide slope 611 to tilt and fix the oiling nozzle 6.

[0078] like Fig.13 - Fig.16As shown, the specific oil filling process is as follows: first align the positioning groove 42 on the housing 4 with the slider 1, and after the top of the slider 1 is completely placed in the positioning groove 42, the cover body 13 contacts the push rod 61, and when the trigger 5 is pressed, the trigger 5 drives the connecting rod 52 to push the push rod 61 forward; the oil filling nozzle 6 is fixed in parallel in the oil outlet push rod by the guide inclined surface 611, and moves forward together with the push rod 61, and the oil filling nozzle 6 moves forward horizontally along the slide groove 431. When the oil filling nozzle 6 moves horizontally to the limit position of the slide groove 431, it no longer moves forward. At this time, the push rod 61 still moves forward, and the guide inclined surface 611 pushes the oil filling nozzle 6 to tilt, so that the third fixed column 63 rotates a certain angle around the slide groove 431 until the bottom surface of the oil filling nozzle 6 is parallel to the guide inclined surface 611. At this time, the push rod 61 pushes the cover body 13 open, and the oil filling nozzle 6 extends into the oil inlet for oiling to prevent the lubricating oil from spilling on the outside. When the trigger 5 is retracted, the push rod 61 moves backward, and the top angle 613 presses against the top surface of the oiling nozzle 6, so that the third fixing column 63 rotates around the slide groove 431 to a horizontal state. When the limiting surface 612 fits with the end surface of the front end of the oiling nozzle 6, the push rod 61 drives the oiling nozzle 6 to move backward to the limiting position.

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