Description

Technical Field

[0001] This utility model belongs to the field of sealing ring technology, specifically relating to a reinforced motor sealing ring. Background Technology

[0002] In practical applications of electric motors, sealing rings are crucial components that prevent dust, liquids, and other impurities from entering the motor and ensure its normal operation. Their sealing performance directly affects the motor's service life and operational stability. Currently, most motors on the market use traditional single interference-fit sealing rings, which rely on their own elasticity to contact the surface of the motor's sealing part to achieve a seal.

[0003] However, traditional sealing rings have shortcomings. During long-term use, the single interference fit structure is prone to elastic decay due to factors such as vibration and temperature changes during motor operation. This leads to gaps between the sealing ring and the motor's sealing components, significantly reducing the sealing effect. This allows dust, liquids, and other impurities to enter the motor, causing damage to motor components and affecting motor performance and reliability. Utility Model Content

[0004] The purpose of this invention is to provide a reinforced motor sealing ring, which aims to solve the problem that when construction workers of varying heights attempt to pass through turnstiles for facial recognition, a significant height difference often arises due to the varying vertical distance between the device and the person's face. This height difference may prevent the camera from accurately capturing and clearly identifying the facial features of all individuals, especially when the face deviates from the optimal recognition area, resulting in a significant reduction in both recognition accuracy and efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reinforced motor sealing ring, comprising a sealing ring, wherein an annular groove is formed on the surface of the sealing ring, and a reinforcing ring is fitted inside the annular groove;

[0006] A ring of protruding rods is installed at equal intervals on the inner wall of the reinforcing ring. A clamp is installed on the end of the protruding rod away from the inner wall of the reinforcing ring. The reinforcing ring is supported and installed in the annular groove of the sealing ring by the protruding rods and the clamp.

[0007] In order to ensure that the reinforcing ring can be firmly installed in the sealing ring, as a reinforced motor sealing ring of this utility model, preferably, the clamp head has a semi-circular structure, and the diameter of the clamp head is larger than the diameter of the protrusion. The mating end of the protrusion and the clamp head is engaged inside the jaw. The diameter of the clamp head is larger than the diameter of the opening end of the jaw. The size of the clamp head is adapted to the internal size of the jaw.

[0008] To facilitate the docking operation between the protruding rod and the corresponding locking head, as a reinforced motor sealing ring of this utility model, preferably, the bottom of the annular groove is connected to the top of the inner groove, and six locking heads are equally spaced on the inner wall of the annular groove near the inner ring of the sealing ring, and the bottom of the reinforcing ring is interference-fitted into the inner groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] After the sealing ring is installed at the motor's output sealing part, the reinforcing ring is then inserted into the annular groove and the inner groove. The position of the reinforcing ring within these grooves is adjusted so that the six sets of protrusions and clips on the inner wall of the reinforcing ring align with the corresponding slots on the inner groove. Each protrusion and clip is manually pressed into its slot, thus securing the reinforcing ring within the sealing ring. The reinforcing ring then expands the sealing ring, creating an additional layer of sealing effect. This allows the sealing ring to fit more snugly against the inner and outer walls of the motor's sealing part, thereby improving the sealing performance. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides the following technical solution: a reinforced motor sealing ring, including a sealing ring 1, an annular groove 2 is formed on the surface of the sealing ring 1, and a reinforcing ring 3 is embedded in the annular groove 2;

[0019] A ring of protruding rods 4 are installed at equal intervals on the inner wall of the reinforcing ring 3. A clamp 5 is installed on the end of the protruding rod 4 away from the inner wall of the reinforcing ring 3. The reinforcing ring 3 is supported and installed in the annular groove 2 of the sealing ring 1 by the protruding rods 4 and the clamp 5.

[0020] Preferably, the clamp head 5 has a semi-circular structure, and the diameter of the clamp head 5 is larger than the diameter of the protrusion 4. The mating ends of the protrusion 4 and the clamp head 5 are engaged inside the bayonet 22. The diameter of the clamp head 5 is larger than the diameter of the opening end of the bayonet 22, and the size of the clamp head 5 is compatible with the internal size of the bayonet 22.

[0021] In practical use, after the bayonet 22 is connected with the corresponding protrusion 4 and the clamp head 5, the protrusion 4 and the clamp head 5 will be constrained by the corresponding bayonet 22 and play a positioning role for the reinforcing ring 3. In this way, the reinforcing ring 3 can be restricted inside the reinforcing ring 3 and will not move easily.

[0022] Preferably, the bottom of the annular groove 2 is connected to the top of the inner groove 21, and six slots 22 are equally spaced on the inner wall of the annular groove 2 near the inner ring of the sealing ring 1, and the bottom of the reinforcing ring 3 is interference-fitted into the inner groove 21.

[0023] In practical use, when installing the motor sealing assembly, the sealing ring 1 must first be precisely embedded into the sealing part of the motor output end. The sealing ring 1 is made of highly elastic rubber, which can initially form a basic sealing layer. After the sealing ring 1 is installed, the assembly of the reinforcing ring 3 begins. The reinforcing ring 3 is inserted into the cavity formed by the annular groove 2 and the inner groove 21.

[0024] After the reinforcing ring 3 is initially positioned, alignment adjustment is required. The inner wall of the reinforcing ring 3 features six sets of evenly distributed protrusions 4 and clamps 5. By rotating and fine-tuning the orientation of the reinforcing ring 3, these protrusions 4 and clamps 5 are precisely aligned axially and radially with the corresponding slots 22 on the side wall of the inner groove 21. After alignment, use a rubber mallet to tap evenly along the circumference of the reinforcing ring 3, and manually apply force to gradually press the protrusions 4 and clamps 5 into the slots 22. During this process, the applied force must be strictly controlled to avoid damage to the sealing components due to excessive force.

[0025] After the reinforcing ring 3 is engaged and fixed, it exerts a uniform radial expansion force on the sealing ring 1 during the engagement process. This expansion not only ensures that the sealing ring 1 fits tightly against the inner wall of the motor's sealing area, forming the first sealing barrier, but also fully compresses the outer wall, constructing a second protective layer. This double-layer sealing structure design effectively eliminates the potential gap issues associated with traditional single-layer seals, significantly improving the overall protective performance of the sealing system and ensuring that the motor maintains excellent sealing performance even under complex operating conditions.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
