Description

Technical Field

[0001] This application relates to the field of electric linear actuators, and more particularly to a high-performance sealing ring for electric linear actuators. Background Technology

[0002] Electric linear actuators, also known as linear actuators, are a new type of linear execution mechanism mainly composed of a motor, a linear actuator, and a control device. With the achievement of the "dual carbon" target and the further acceleration of the construction of large-scale new energy photovoltaic bases, solar tracking systems have ushered in a new era of development. Electric linear actuators, as key auxiliary equipment in solar tracking systems, play a vital role due to their high safety, high adaptability, and high profitability.

[0003] Photovoltaic electric linear actuators are mostly installed in harsh environments such as deserts, Gobi deserts, and even oceans. In such harsh environments, the moisture or dust content increases, which raises the requirements for sealing the gap between the sliding rod and the cylinder of the photovoltaic electric linear actuator. However, the sealing ring structure on the existing photovoltaic electric linear actuator is simple. In harsh environments, the sliding rod is prone to sticking to the seal during sliding, which can bring water or dust into the cylinder and cause damage to the photovoltaic electric linear actuator. Utility Model Content

[0004] To improve the sealing effect of the sealing ring, this application provides a high-performance sealing ring for electric push rods.

[0005] The electric actuator high-performance multi-action sealing ring structure provided in this application adopts the following technical solution:

[0006] A high-performance sealing ring for an electric push rod includes a ring body, one end of which is inserted into a cylinder and the other end extends out of the cylinder. A dustproof lip is fixedly provided on the ring body. The dustproof lip is integrally formed and fixed at the end of the ring body that extends out of the cylinder. The dustproof lip is inclined toward the sliding rod and abuts against the sliding rod through deformation.

[0007] By adopting the above technical solution, the dustproof lip can block sand or water adhering to the sliding rod, thereby improving the sealing effect of the sealing ring and reducing the probability of sand or water adhering to the sliding rod entering the cylinder and causing damage to the photovoltaic electric push rod.

[0008] Optionally, grooves are formed on the ring body.

[0009] By adopting the above technical solution, the groove can make the gap between the cylinder and the sealing ring step-like, thereby improving the sealing effect of the cylinder and the sealing ring.

[0010] Optionally, the trench sidewalls are chamfered.

[0011] By adopting the above technical solution, the chamfering facilitates the insertion of the guide cylinder into the groove.

[0012] Optionally, the ring body is inserted into the cylinder body and a spill-proof lip is fixed at one end.

[0013] By adopting the above technical solution, the anti-overflow lip design can reduce the probability that grease in the cylinder is carried out of the cylinder by the sliding rod, while also ensuring the thickness of the grease film and reducing the probability of dry friction causing a shortened seal life.

[0014] Optionally, the anti-overflow lip is provided on both sides of the ring body, and the anti-overflow lip on both sides is inclined away from the ring body.

[0015] By adopting the above technical solution, the anti-overflow lips set on both sides are used to reduce the probability of grease sticking to the sliding rod and causing grease to be carried out of the cylinder body, and to reduce the probability of grease leaking out from the gap between the ring body and the cylinder body.

[0016] Optionally, a deformation groove is provided between the anti-overflow lips on both sides.

[0017] By adopting the above technical solution, the deformation groove can provide space for the deformation of the anti-overflow lip, avoiding the probability of damage caused by the anti-overflow lips on both sides always being in a state of mutual compression.

[0018] Optionally, a guide slope is provided at one end of the ring body extending out of the cylinder body, and the guide slope is inclined in the direction away from the sliding rod.

[0019] By adopting the above technical solution, the guide slope can direct the blocked water and sand away from the sliding rod, reducing the probability of water and sand accumulating at the sealing ring.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] By using the dustproof lip to abut against the sliding rod, sand or water adhering to the sliding rod can be blocked, thereby improving the sealing effect of the sealing ring and reducing the probability of sand or water adhering to the sliding rod entering the cylinder and causing damage to the photovoltaic electric push rod.

[0022] The grooves allow the gap between the cylinder and the sealing ring to be stepped, thereby improving the sealing effect of the cylinder and the sealing ring.

[0023] The anti-overflow lip design reduces the probability of grease being carried out of the cylinder by the sliding rod, while also ensuring the thickness of the grease film and reducing the probability of dry friction shortening the seal life.

[0024] The guide slope can direct blocked water and sand away from the sliding rod, reducing the probability of water and sand accumulating at the sealing ring. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] This application discloses a high-performance sealing ring for an electric actuator, referring to... Figure 1 , Figure 2 and Figure 3The system includes a ring body 1. In this embodiment, the ring body 1 is a sealing ring made of high-temperature and low-temperature resistant rubber. The high-temperature and low-temperature resistant rubber can be fluororubber, silicone rubber, etc. One end of the ring body 1 is inserted into the cylinder body 8 and the other end extends out of the cylinder body 8. A dustproof lip 2 is fixed on the ring body 1. The dustproof lip 2 is integrally formed and fixed at the end of the ring body 1 that extends out of the cylinder body 8. The dustproof lip 2 is inclined towards the sliding rod 9 and abuts against the sliding rod 9 through deformation. By abutting against the sliding rod 9 through the dustproof lip 2, sand or water adhering to the sliding rod 9 can be blocked, thereby improving the sealing effect of the sealing ring and reducing the probability that sand or water adhering to the sliding rod 9 will enter the cylinder body 8 and cause damage to the photovoltaic electric push rod.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The ring body 1 extends out of the cylinder 8 and has a guide slope 7 at one end. The guide slope 7 is inclined away from the sliding rod 9. When the dustproof lip 2 abuts against the sliding rod 9 and deforms, the dustproof lip 2 is inclined away from the cylinder 8 towards the guide slope. The inclination of the guide slope 7 and the dustproof lip 2 can guide the blocked water and sand away from the sliding rod 9, reducing the probability of water and sand accumulating at the sealing ring, thereby reducing the probability of water and sand penetrating into the cylinder 8 due to large and long-term accumulation. The dustproof lip 2 is pointed at the end that abuts against the sliding rod 9. The pointed dustproof lip 2 can better scrape off the water or sand stuck on the rod.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The cylinder body 1 has a groove 3. The groove 3 makes the gap between the cylinder body 8 and the sealing ring step-shaped, thereby improving the sealing effect of the cylinder body 8 and the sealing ring. The side wall of the groove 3 has a chamfer 4. The chamfer 4 facilitates the insertion of the cylinder body 8 into the groove 3.

[0034] Reference Figure 1 , Figure 2 and Figure 3The ring body 1 is inserted into the cylinder body 8 and has an integrally formed anti-overflow lip 5 at one end. The anti-overflow lip 5 reduces the probability that the grease in the cylinder body 8 will be carried out of the cylinder body 8 by the sliding rod 9, and also ensures the thickness of the grease film, reducing the probability of dry friction causing a shortened seal life. The anti-overflow lip 5 is provided on both sides of the ring body 1, and both sides of the anti-overflow lip 5 are inclined away from the ring body 1. The side of the anti-overflow lip 5 that abuts against the sliding rod 9 is used to reduce the probability that the sliding rod 9 will stick to the grease and carry the grease out of the cylinder body 8, and the side that abuts against the cylinder body 8 is used to reduce the probability that the grease will leak out of the gap between the ring body 1 and the cylinder body 8. A deformation groove 6 is opened between the two sides of the anti-overflow lip 5. The deformation groove 6 provides space for the deformation of the anti-overflow lip 5, and avoids the probability of damage caused by the two sides of the anti-overflow lip 5 being in a state of mutual compression during deformation.

[0035] The implementation principle of this application embodiment is as follows: the ring body 1 is fitted onto the sliding rod 9, and the ring body 1 is inserted into the gap between the sliding rod 9 and the cylinder 8 by sliding, and the protrusion at the end of the cylinder 8 is inserted into the groove 3, so that the cylinder 8 and the groove 3 abut against each other to form a stepped gap, thereby reducing the probability of water and sand seeping in. The dustproof lip 2 and the anti-overflow lip 5 facing the sliding rod 9 abut against the sliding rod 9 and deform. The anti-overflow lip 5 facing the cylinder 8 abuts against the cylinder 8 and deforms. When the sliding rod 9 slides out of the cylinder 8, the grease adhering to the sliding rod 9 inside the cylinder 8 will be blocked by the deformed anti-overflow lip 5. When the sliding rod 9 slides back into the cylinder 8, the water or sand adhering to the sliding rod 9 outside the cylinder 8 will be blocked by the dustproof lip 2.

Although this specification has described this application in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to this application.
