[0002] An oil level gauge (also known as an oil level indicator or sight glass) is typically mounted on the side of the vibrator or on the oil tank, allowing observation of the lubricating oil level through a transparent window. The vibrator body has a side wing block for mounting the oil level gauge; the side wing block has upper and lower through holes, connecting to the lubrication chamber. The oil level gauge is connected to the vibrator body via a guide bolt, which has a cavity and an oil passage hole, thus connecting the oil tank and the lubrication chamber. By utilizing the through holes in the side wing block and the cavity holes in the guide bolt, the lubrication chamber and oil tank are directly connected, allowing changes in oil level to reflect the lubrication status, while simultaneously preventing oil circuit damage or leakage caused by vibration.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Depend on Figures 1 to 10 Provided is an oil level mirror for a vibrator, comprising an oil level mirror housing 1 mounted on the vibrator, characterized in that the oil level mirror housing 1 has an upper channel 101 and a lower channel 102 inside, and an oil level display channel 103 connecting the upper channel 101 and the lower channel 102 inside the oil level mirror housing 1. At least one side of the oil level mirror housing is capable of displaying the oil level display channel, and this side is made of transparent material to display the height of the oil level inside the oil level mirror housing 1. An upper bolt 2 is provided in the upper channel 101, and the upper bolt 2 is screwed onto the vibrator 5 at one end facing the vibrator. The upper bolt 2 has an upper bolt channel 201 connecting the inside of the vibrator 5 and the oil level display channel 103. An outlet is provided on the side wall of the upper bolt near the head of the upper bolt. The outlet hole is connected to the upper channel and then to the oil level indicator channel 103. The lower channel 102 is provided with a lower bolt 3. The lower bolt 3 is screwed onto the vibrator at one end facing the vibrator. The lower bolt 3 is provided with a lower bolt channel 301 that connects the inside of the vibrator and the oil level indicator channel 103. The lower bolt is provided with an outlet hole on the side wall near the head of the lower bolt. The outlet hole is connected to the lower channel and then to the oil level indicator channel 103. The upper bolt 2 and the lower bolt 3 are suspended on the vibrator housing to install the oil level indicator housing 1. At the same time, the channels provided in the upper bolt 2 and the lower bolt 3 are used to connect the oil level indicator channel 103 and the inside of the vibrator. Thus, the lubricating oil of the vibrator can enter the oil level indicator channel 103 to display the oil level inside the vibrator. The vibrator is connected to the lower bolt channel 301 inside the lower bolt 3, and then to the oil level indicator channel 103 through the lower channel 102. Then, it is connected to the inside of the vibrator through the upper channel 101 and the upper bolt channel 201 to form a closed loop, thus completing the display of the oil level.

[0025] Sealing rings 4 are provided at both ends of the upper channel 101 and both ends of the lower channel 102. The sealing rings 4 are located at the contact points between the upper channel 101 and the vibrator, and between the upper channel 101 and the head of the upper bolt 2. The sealing rings 4 are also located at the contact points between the lower channel 102 and the vibrator, and between the lower channel 102 and the head of the lower bolt 3, to prevent leakage of lubricating oil inside the vibrator and lubricating oil entering the oil level mirror. The diameters at both ends of the upper channel 101 are larger than its inner diameter. The sealing rings 4 are placed in the larger diameter holes at both ends of the upper channel 101, and the upper bolt 2 is inserted into the upper channel 101 with a clearance fit to the oil level mirror housing 1. Similarly, the diameters at both ends of the lower channel 102 are larger than its inner diameter. The sealing rings 4 are placed in the larger diameter holes at both ends of the lower channel 102, and the lower bolt 3 is inserted into the lower channel 102 with a clearance fit to the oil level mirror housing 1.

[0026] The oil level mirror housing 1 is provided with an upper contact surface 104 and a lower contact surface 105 on the side facing the exciter 5. The lower contact surface 105 is closer to the vertical plane where the exciter axis is located than the upper contact surface 104. The upper channel 101 passes through the upper contact surface 104, and the lower channel 102 passes through the lower contact surface 105. The upper contact surface is located above the lower contact surface. The installation position of the vibrator 5 housing and the oil level mirror is such that the upper side is further out than the lower side. The design of the oil level mirror housing 1 allows it to be better installed on the vibrator housing, thereby better displaying the lubricating oil level in the vibrator. The upper contact surface 104 and the lower contact surface 105 of the oil level mirror housing 1 are in contact with the vibrator housing. The middle part of the side of the oil level mirror housing 1 facing the vibrator is not in contact with the vibrator. This reduces the contact surface between the oil level mirror housing 1 and the vibrator, reduces the machining surface of the vibrator housing and the oil level mirror housing 1, improves the fitting accuracy between the oil level mirror housing 1 and the vibrator housing, and thus improves the sealing effect between the oil level mirror and the vibrator.

[0027] The projection of the oil level indicator channel 103 onto a vertical plane perpendicular to the upper channel 101 is rectangular, and its width on the vertical plane perpendicular to the upper channel 101 is greater than that of the upper channel 101 and the lower channel 102. The width of the oil level indicator channel is more than twice the diameter of the upper channel. The upper and lower channels are located on one side of the oil level mirror housing. The large size of the oil level indicator channel forms a cavity that can accommodate lubricating oil. While displaying the oil level of the vibrator, it can also provide lubricating oil to the vibrator, thus acting as a secondary oil chamber for storing lubricating oil in the vibrator.

[0028] The connecting surface between the upper contact surface 104 and the lower contact surface 105 is an inclined surface 107.

[0029] The opposite side of the inclined surface 107 is a vertical surface.

[0030] The opposite surface of the inclined surface 107 is parallel to the inclined surface 107.

[0031] The connecting surface between the upper contact surface 104 and the lower contact surface 105 is an arc-shaped surface.

[0032] The oil level mirror housing 1 is made of transparent plastic, and the oil level mirror housing 1 is provided with scale lines 106 to display the oil level. The entire oil level mirror housing 1 is made of transparent plastic, which facilitates manufacturing and processing, and at the same time allows the oil level to be displayed from multiple directions, making it easy to observe the oil level of the vibrator.

[0033] The beneficial effects of this utility model are as follows: The oil level mirror is installed by fitting with the vibrator housing using two different contact surfaces. This not only adapts to the shape of the vibrator housing but also reduces the contact surface with the vibrator housing, thereby reducing the size of the machined surface of the vibrator housing, saving costs, and improving fitting accuracy and sealing performance. The oil level mirror housing is directly installed on the vibrator by upper and lower bolts, which are also provided with channels for supplying lubricating oil. The structural design is simple, facilitates sealing, and thus improves the sealing effect.

[0034] The embodiments described above are not intended to limit the scope of this utility model. Any modifications and improvements made to the technical solutions of this utility model by those skilled in the art without departing from the design concept of this utility model should be included within the protection scope defined by the claims of this utility model.
