Description

Technical Field

[0001] The utility model relates to the technical field of treadmills, in particular to a hidden refueling mechanism for a treadmill. Background Art

[0002] Most existing treadmills drive the running belt to rotate circumferentially through rollers. In order to increase the service life of the running belt and reduce abnormal noise caused by friction between the running belt and the rollers, it is usually necessary to add lubricating oil to the running belt at regular intervals to ensure the normal use of the treadmill.

[0003] The existing treadmill refueling mechanism generally includes a refueling pipe and a refueling nozzle. The refueling nozzle adopts an L-shaped structure and is installed on a square tube on one side of the base. The vertical end of the refueling nozzle points to the top surface of the base and is covered with a decorative cover. The horizontal end of the refueling nozzle points to the bottom of the running board. The refueling pipe is attached to the bottom surface of the running board and its oil inlet is connected to the horizontal end of the refueling nozzle. In this way, lubricating oil is fed from the refueling nozzle and reaches the refueling pipe, and then drips onto the running belt from the drip holes arranged at intervals on the refueling pipe. In addition, there are also two L-shaped refueling nozzles, which are installed on the square tubes on both sides of the base, and the two ends of the refueling pipe are connected to two L-shaped refueling groups.

[0004] At present, the refueling mechanism can well perform the function of refueling lubricating oil. However, after being used for a period of time, oil leakage is prone to occur at the connection between the refueling nozzle and the refueling pipe. The lubricating oil drips to areas outside the running belt, which is difficult to clean and also wastes the lubricating oil. Because the running board is stepped on by both feet during running, the running board will float up and down, and then the refueling pipe that is in contact with the running board will also move up and down. Over time, a gap will be generated between the refueling pipe and the refueling nozzle. Utility Model Content

[0005] The utility model aims to provide a hidden oiling mechanism for a treadmill, which can conveniently add lubricating oil and greatly reduce the oil leakage caused by the up and down floating of a running board.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A hidden refueling mechanism for a treadmill comprises a refueling tank, a refueling hose and a refueling nozzle. The refueling tank is fixedly mounted on the bottom of the running board of the treadmill and a plurality of oil dripping holes are provided at the bottom of the refueling tank. The refueling nozzle is fixedly mounted on the side of the base of the treadmill. The installation height of the refueling nozzle is higher than the installation height of the refueling tank. The refueling hose is connected between the refueling nozzle and the refueling tank. A decorative cover covering the refueling nozzle is detachably provided on the side of the base.

[0008] Preferably, the decorative cover is snap-fitted with the base.

[0009] Preferably, a mounting seat is protruding from the top of the refueling tank, and the mounting seat is fixed to the running gear by fastening bolts.

[0010] Preferably, the bottom of the oil filling groove is a flat-bottomed V-shaped groove, and the oil dripping hole passes through the flat bottom surface of the flat-bottomed V-shaped groove.

[0011] Preferably, the refueling hose is a silicone hose.

[0012] Preferably, a tooth-shaped hole is formed at one end of the refueling tank close to the refueling hose, and the tooth-shaped hole is engaged and fixed with the refueling hose.

[0013] Preferably, a plug-in column is extended and protruded from one side of the refueling nozzle close to the refueling hose, the refueling hose is in socket-and-spigot fit with the plug-in column, and a refueling channel is penetrated through the plug-in column.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model comprises a hidden refueling mechanism including a refueling nozzle, a refueling hose and a refueling tank. The refueling tank is fixed at the bottom of the running board and floats up and down with the running board, which can prevent the refueling tank from being squeezed and damaged by the up and down floating of running, and can also drive the lubricating oil in the refueling tank to flow and distribute more evenly by stepping on the running board. The refueling hose flexibly connects the refueling tank box and the refueling nozzle, which can greatly reduce the oil leakage caused by the up and down floating of the running board. The refueling hose and the refueling tank are fixed by bite through the toothed hole, and the refueling hose and the refueling nozzle are matched by the plug-in column, which can greatly enhance the stability and firmness of the installation structure of the refueling hose.

[0021] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0022] like Figure 1-Figure 4 As shown, this embodiment provides a hidden refueling mechanism for a treadmill, including a refueling tank 30, a refueling hose 20 and a refueling nozzle 10. The hidden refueling mechanism is applied to a treadmill.

[0023] The treadmill includes a base, a running deck 41, a running belt and a column. The column is located on the front side of the base. The base includes a left square tube 42 and a right square tube. The running belt transmits circumferentially back and forth. The running deck 41 is floatingly installed between the left square tube 42 and the right square tube through a shock-absorbing assembly and is located inside the running belt. The hidden refueling mechanism is arranged on the side of the left square tube 42 away from the column.

[0024] In this embodiment, the refueling tank 30 is made of hard plastic or metal, in a straight line shape, with an open top and arranged horizontally. Mounting seats 31 are arranged at intervals on the left and right sides of the top of the refueling tank 30. The mounting seats 31 protrude from the refueling tank 30 and the top surface of the mounting seats 31 is at the same level as the top surface of the refueling tank 30. The mounting seats 31 are provided with threaded through holes, and the running board 41 is also provided with threaded blind holes at positions corresponding to the threaded through holes. Then, the refueling tank 30 is fixedly installed on the bottom of the running board 41 of the treadmill by fastening bolts through the threaded through holes and the threaded blind holes. When the refueling tank 30 moves to the lowest position with the running board 41, there is still a gap between the refueling tank 30 and the running belt below.

[0025] The bottom of the oil filling groove 30 is a flat-bottomed V-shaped groove, and a plurality of oil dripping holes are arranged at intervals on the flat bottom surface of the flat-bottomed V-shaped groove. The oil dripping holes penetrate the flat-bottomed V-shaped groove. When the lubricating oil enters the oil filling groove 30, it flows and distributes in the oil filling groove 30 by utilizing its fluidity, and drips from the oil dripping holes onto the treadmill below. The treadmill belt can be run while dripping to achieve the goal of having lubricating oil on the treadmill belt.

[0026] In this embodiment, the oil nozzle 10 includes an oil nozzle body and two connecting ears connected to the left and right sides of the oil nozzle body. The connecting ears are provided with screw holes. The side of the left square tube 42 is respectively adapted with matching holes corresponding to the oil nozzle body and the connecting ears. The oil nozzle 10 is fixedly installed on the side of the base of the treadmill (specifically, the side of the left square tube 42). In addition, in order to prevent dust from contaminating the oil nozzle 10, this embodiment also has a decorative cover 43 snap-fitted on the base. The decorative cover 43 covers the oil nozzle 10. The decorative cover 43 can be removed when refueling, and reset and fixed after refueling. In this way, the entire oiling mechanism is hidden and not exposed to the outside, and the appearance of the treadmill is not affected.

[0027] In the present embodiment, the refueling hose 20 is connected between the refueling nozzle 10 and the refueling tank 30. The refueling hose 20 is a silicone hose. A toothed hole 32 is provided at one end of the refueling tank 30 near the refueling hose 20, and the toothed hole 32 is engaged and fixed with the refueling hose 20. A plug-in column 11 is extended and protruded from one side of the refueling nozzle 10 near the refueling hose 20. The refueling hose 20 and the plug-in column 11 are in a socket-and-spigot fit. The plug-in column 11 is inserted into one end of the refueling hose 20 and tightens the refueling hose 20 to firmly connect the two. A refueling channel is provided through the plug-in column 11. The lubricating oil entering from the refueling nozzle 10 enters the refueling tank 30 through the refueling hose 20. Since the refueling hose 20 is used, it has certain tensile toughness and flexibility, and realizes a flexible connection with the refueling nozzle 10 and the refueling tank 30, which greatly reduces the oil leakage caused by loosening of the connection or gaps caused by the up and down floating of the running board 41. The engagement and fixation of the toothed hole 32 can also further enhance the connection firmness.

[0028] The installation height of the oil filling nozzle 10 is higher than the installation height of the oil filling groove 30 , so that the lubricating oil can smoothly enter the oil filling groove 30 .
