[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-6 , the present utility model provides a technical solution: a bearing seat with a sealing structure, including a bearing mounting seat 1, wedge-shaped grooves 11 are symmetrically arranged on the middle side walls at both ends of the bearing mounting seat 1, sealed semi-rings 2 are symmetrically arranged at both ports of the bearing mounting seat 1 and are in contact with the side wall of the bearing mounting seat 1, wedge-shaped blocks 21 are integrally formed and connected on the side walls of the sealed semi-rings 2, and the wedge-shaped blocks 21 are correspondingly arranged in the wedge-shaped grooves 11;
[0021] Both ends of the bearing mounting seat 1 are symmetrically provided with a mounting groove located between the wedge-shaped grooves 11, and locking assemblies 3 are provided in the mounting grooves. The locking assembly 3 includes a shaft rod 31, and a threaded portion 32 is provided in the middle of the shaft rod 31. Symmetrically arranged clamping columns 33 are movably inserted at both ends of the shaft rod 31. The clamping columns 33 pass through the mounting groove, and the ends of the clamping columns 33 are provided with inclined surfaces. The side wall of the clamping column 33 is in contact with the wedge-shaped block 21, and a return spring 34 wrapped around the shaft rod 31 is connected between the side wall of the threaded portion 32 and the side wall of the clamping column 33.
[0022] Furthermore, the inner diameter of the sealing half-ring 2 is smaller than the inner diameter of the bearing mounting seat 1, and the outer diameter of the sealing half-ring 2 is larger than the inner diameter of the bearing mounting seat 1. The port of the bearing mounting seat 1 is sealed by the ring structure formed by the sealing half-rings 2, and only the bearing installed inside the bearing mounting seat 1 is sealed and limited.
[0023] Furthermore, the ends of the upper part of the sealing half-ring 2 are connected by a clamping block and a clamping groove. A clamping block is provided at the end of the upper part of one of the sealing half-rings 2, and a clamping groove is provided at the end of the upper part of the other opposite sealing half-ring 2. Through the connection of the clamping block and the clamping groove, the stability and strength of the connection of the sealing half-ring 2 are enhanced.
[0024] Furthermore, an internal thread is provided in the middle of the mounting groove, and the threaded portion 32 is threadedly connected to the internal thread. Through the threaded connection of the threaded portion 32 and the internal thread, it is convenient to install the locking assembly 3 in the mounting groove.
[0025] Furthermore, limiting strips 311 are symmetrically provided on the side wall of the shaft rod 31, and limiting grooves are symmetrically provided on the inner wall of the clamping column 33. The limiting strips 311 are correspondingly clamped in the limiting grooves. By using the limiting strips 311 and the limiting grooves, the constant angular position of the clamping column 33 is ensured. When the sealing half-ring 2 is moved and installed on the wedge-shaped groove 11, the wedge-shaped block 21 first presses the end inclined surface of the clamping column 33, and then clamps the wedge-shaped block 21 through the end side wall, realizing the installation of the sealing half-ring 2.
[0026] Furthermore, a cross groove 331 is provided on the inclined surface of the clamping column 33. By providing the cross groove 331, it is convenient to install the locking assembly 3 with a cross screwdriver.
[0027] Specifically, after the bearing is pressed into the bearing seat for installation, the wedge-shaped block 21 on the sealing half-ring 2 is moved along the wedge-shaped block 21. The lowest end of the inclined surface of the end of the clamping column 33 is flush with the wedge-shaped block 21. The wedge-shaped block 21 will press the end of the clamping column 33. When the wedge-shaped block 21 moves to the inner end of the wedge-shaped groove 11, the opposite sealing half-ring 2 closes. And under the elastic force of the return spring 34, the clamping column 33 resets, and the side wall of the clamping column 33 is in contact with the wedge-shaped block 21, clamping the wedge-shaped block 21 and the sealing half-ring 2, thereby sealing and limiting the bearing in the bearing seat. The operation is simple, the installation is convenient, and it has practicability.
[0028] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
