Description

Technical Field

[0001] This utility model relates to the technical field of oil level gauges, specifically a tubular oil level gauge. Background Technology

[0002] Oil level gauges are mainly used to indicate the oil level in oil containers (such as oil tanks) or to monitor the condition of lubricating oil in equipment. Its main body is generally made of a transparent material (such as plexiglass), such as the oil level indicator disclosed in the document with Chinese Patent Publication No. CN213118419U. It includes an oil level indicator connector, an oil level indicator seat, and an oil level indicator body. The oil level indicator connector includes a connecting pipe, a metal corrugated hose, and a pressure pipe that fixes the metal corrugated hose to the connecting pipe. The oil level indicator seat includes a seat body and an L-shaped flow channel set in the seat body. The seat body is provided with an upper connecting hole and a lower connecting hole that connect to the flow channel. The connecting pipe is screwed into the upper connecting hole. The oil level indicator body includes an oil level indicator tube extending vertically and a fixing tube that connects the oil level indicator tube to the lower connecting hole. The oil level indicator tube is at least partially accommodated in the inner hole of the fixing tube, and the inner cavity of the oil level indicator tube is open to the atmosphere. The oil level indicator tube is a transparent tube. A window is opened on one side of the fixing tube, and a scale is provided. The lower end of the metal corrugated hose faces downward and is not higher than the lowest scale line of the scale. Using such an oil level indicator can accurately reflect the level of lubricating oil in the bearing housing, and it has good sealing performance, strong visibility, and is easy to install and remove.

[0003] However, since the oil or lubricating oil being tested inevitably contains some impurities, after a period of use, some impurities will adhere to the inner wall of the tubular body, which will affect the observation of the oil level and, in severe cases, even affect the operation of the equipment. Therefore, it is necessary to periodically disassemble and clean the inner wall of the tubular body. While this achieves the purpose of cleaning the tubular body, the assembly and disassembly are cumbersome, time-consuming, and labor-intensive. Furthermore, repeated assembly and disassembly can affect its sealing effect, thus requiring further improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a new type of oil level indicator with self-cleaning function, which is based on the current state of the technology, so as to facilitate the cleaning of the inner wall of the tubular body.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a novel oil level indicator, comprising a tubular body, with an oil inlet at the lower part of the tubular body communicating with the inner cavity of the tubular body, characterized in that: it further comprises a push button partially constrained in the upper port of the tubular body and capable of sliding up and down, a movable seat located below the push button and driven by the push button to rotate and move down, and an elastic element installed in the tubular body, wherein the elastic element enables the movable seat and the push button to always have an upward tendency, and a bracket that can rotate together with the movable seat is also connected to the movable seat, and a rubbing strip that can contact the inner wall of the tubular body is installed on the bracket.

[0006] When the oil level indicator needs cleaning, press the push button. The push button drives the movable seat to move downwards in a circumferentially rotating manner relative to the tubular body. At the same time, the movable seat drives the connected bracket to rotate together, allowing the wiping strip on the bracket, which is in contact with the inner wall of the tubular body, to rotate circumferentially relative to the tubular body, thereby cleaning the inner wall of the tubular body. After releasing the push button, the push button and movable seat move upwards and reset under the action of the elastic element.

[0007] Therefore, this utility model can achieve self-cleaning of the inner wall of the tubular body by pressing the push button, which is convenient to operate.

[0008] To enable the movement of the push button to drive the rotation and movement of the movable seat, preferably, a spiral groove is formed on the outer peripheral wall of the movable seat, and a limiting protrusion is provided on the inner wall of the tubular body to accommodate the spiral groove. The cooperation between the spiral groove and the limiting protrusion allows the movable seat to move up and down in a circumferentially rotating manner.

[0009] Preferably, there are at least two spiral grooves evenly distributed circumferentially, and correspondingly, there are also two limiting protrusions, so that the movable seat is subjected to uniform force and rotates smoothly.

[0010] Preferably, the bracket includes a rod, an upper mounting plate and a lower mounting plate fixed on the rod, the upper end of the rod is slidably inserted into the center hole of the movable seat, and the upper and lower ends of the wiping strip are respectively connected to the upper and lower mounting plates.

[0011] To improve cleaning effectiveness, preferably, there are at least two wiping strips evenly distributed circumferentially.

[0012] The aforementioned elastic element can be an existing spring, sheet metal, etc. Preferably, the elastic element is a spring whose lower end abuts against the inner wall of the tubular main body and whose upper end abuts against the movable seat.

[0013] Preferably, the oil inlet is located on the side wall of the tubular body and is connected to an oil inlet pipe with a control valve.

[0014] Furthermore, an oil drain valve is installed at the lower end of the tubular body.

[0015] Under normal operating conditions, the control valve is open and the drain valve is closed. When it is necessary to clean the oil level indicator, close the control valve, and after cleaning is complete, open the drain valve to drain the cleaned oil.

[0016] Preferably, the upper end of the tubular body is fitted with a limiting plug with a through hole, and the push button is loosely inserted into the through hole.

[0017] In the above embodiments, preferably, a pressure cap is provided inside the tubular body to divide the inner cavity of the tubular body into an upper cavity and a lower cavity. The push button, movable seat, and elastic element are located in the upper cavity. The upper end of the bracket passes through the pressure cap and is connected to the movable seat. The rubbing strip is located in the lower cavity. In this way, the elastic element is easy to install and the operation is stable.

[0018] Compared with existing technologies, this invention features a push button, a movable seat that rotates downwards driven by the push button, a support that rotates with the movable seat, and an elastic element that ensures the movable seat and push button always have an upward tendency. When the oil level indicator needs cleaning, pressing the push button drives the movable seat to move downwards in a circumferentially rotating manner relative to the tubular body. Simultaneously, the movable seat drives the connected support to rotate, allowing the wiping strip on the support, which contacts the inner wall of the tubular body, to rotate circumferentially relative to the tubular body, thus cleaning the inner wall of the tubular body. Releasing the push button causes the push button and movable seat to move upwards and reset under the action of the elastic element.

[0019] Therefore, this utility model can achieve self-cleaning of the inner wall of the tubular body by pressing the push button, which is convenient to operate. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 6 As shown, this is a preferred embodiment of the novel oil level indicator of the present invention. The novel oil level indicator includes a tubular body 1, a push button 2, a movable seat 3, an elastic element 4, a bracket 5, a control valve 6, a drain valve 7, and a limit plug 8.

[0028] The tubular body 1 is vertically arranged, and its lower side wall has an oil inlet 1a that connects to the inner cavity of the tubular body 1. The oil inlet 1a is connected to an oil inlet pipe 12 with a control valve 6. An oil drain valve 7 is installed at the lower port of the tubular body 1. Both the control valve 6 and the oil drain valve 7 are existing technologies and are used to control the opening or closing of the oil inlet 1a and the lower port, respectively.

[0029] A limiting plug 8 with a through hole 80 is installed at the upper end of the tubular body 1. The lower part of the push button 2 is loosely inserted into the through hole 80 so that the push button 2 can slide up and down relative to the tubular body 1. During the sliding process, the air inside the tubular body can be discharged in time by utilizing the gap between the push button 2 and the through hole 80 to ensure the smooth sliding of the push button. At the same time, a protective cover 9 is provided at the upper end of the tubular body 1. The protective cover 9 covers the outer periphery of the upper part of the push button 2, and the protective cover 9 can detach from the tubular body 1 to expose the upper part of the push button 2. In this way, when not in use, the protective cover can prevent external impurities from falling into the through hole through the aforementioned gap, ensuring the smooth sliding of the push button.

[0030] The movable seat 3 is cylindrical with an axially penetrating central hole 31 inside. It is vertically positioned inside the tubular body 1 and below the push button 2. Driven by the downward-moving push button 2, the movable seat 3 can move downwards in a circumferentially rotating manner relative to the tubular body 1. Specifically, the outer peripheral wall of the movable seat 3 has two (or three or more) circumferentially distributed spiral grooves 30, and the inner wall of the tubular body 1 has limiting protrusions 11 that can be accommodated in the corresponding spiral grooves 30. When the movable seat 3 moves downwards under the drive of the push button 2, it can simultaneously rotate circumferentially relative to the tubular body.

[0031] The aforementioned bracket 5 includes a vertically extending rod 50. The upper end of the rod 50 is slidably inserted into the central hole 31 of the movable seat 3, allowing the movable seat 3 to rotate circumferentially along with the rod 50, and the movable seat to move up and down relative to the upper end of the rod 50. To ensure that the movable seat 3 can only rotate with the rod 5, in this embodiment, the cross-section of the central hole 31 of the movable seat is non-circular (e.g., cross-shaped), and the cross-sectional shape of the upper end of the rod 50 matches the cross-sectional shape of the central hole 31, so that the movable seat can be fitted onto the outer periphery of the upper end of the rod 50 in a way that allows it to move up and down, and can rotate circumferentially along with the upper end of the rod 50. The aforementioned bracket 5 also includes an upper mounting plate 52 fixed to the upper part of the rod 50 and a lower mounting plate 53 fixed to the lower end of the rod 50, with the upper mounting plate 52 located on the lower side of the upper end of the rod 50. Meanwhile, in this embodiment, the bracket 5 is equipped with two wiping strips 51 that can contact the inner wall of the tubular body 1. These wiping strips 51 are evenly distributed around the periphery of the rod 50, and the upper and lower ends of each wiping strip 51 are respectively connected to the upper and lower mounting plates. The wiping strips 51 can clean the inner wall of the tubular body 1 when the rod 50 rotates.

[0032] The aforementioned elastic element 4 is a spring, which is sleeved on the outer periphery of the rod 50 and located on the upper side of the upper mounting plate 52. The lower end of the spring abuts against the inner wall of the tubular body 1 and the upper end abuts against the movable seat 3, so that the movable seat 3 and the push button 2 always have an upward tendency.

[0033] Meanwhile, in order to facilitate the installation of the above-mentioned spring, in this embodiment, a pressure cap 10 is provided inside the tubular body 1, which divides the inner cavity of the tubular body 1 into an upper cavity 101 and a lower cavity 102. The push button 2, the movable seat 3 and the elastic element 4 are located in the upper cavity 101. The upper end of the rod 50 passes through the pressure cap 10 and is connected to the movable seat 3. The rubbing strip 51 is located in the lower cavity 102.

[0034] Furthermore, in order to prevent the bracket 5 from moving down with the movable seat 3, a baffle 20 that abuts against the lower mounting plate 53 is provided in the lower cavity 102. An oil drain hole 201 is provided on the baffle, and the oil inlet 1a is located on the side wall of the tubular body 1 above the baffle 20. In this way, the oil in the lower cavity 102 can be discharged through the oil drain hole 201 and the oil drain valve 7.

[0035] Under normal operating conditions, control valve 6 is open and drain valve 7 is closed. When cleaning the oil level indicator is required, close control valve 6 and press push button 2 to drive the wiping strip 51 to rotate circumferentially along the inner wall of the tubular body 1 to clean the inner wall of the tubular body 1. After cleaning is complete, open drain valve 7 to drain the cleaned oil.
