Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of loader repair port locking, and specifically relates to a repair port locking mechanism. Background Technique
[0002] Maintenance ports are often opened on the rear hood of loaders to facilitate the repair of components such as engines, thus avoiding the need to completely remove the rear hood during maintenance and facilitating maintenance.
[0003] At present, the repair port cover plates of loaders are mainly rotary lock structures (with lock cores or knobs). The lock tongue limiting mechanism requires high manufacturing precision. During the installation and adjustment process, due to welding deviations of the limiting blocks, the lock tongue and the limiting blocks often cannot be properly lapped, resulting in the loss of the locking function, and then the repair cover plate cannot be properly locked. Moreover, the rotary lock structure is relatively complex and is prone to lock core blockage due to dust entry under harsh working conditions. At this time, when the staff performs the unlocking and locking actions, the lock core will be damaged and the lock core will fail. In addition, the lock core is also prone to falling off during the bumping process, resulting in the loss of the locking function, and then the cover plate cannot be properly locked. Therefore, there is a need for a repair port locking mechanism to solve the problems caused by locking through the lock core. Content of the Utility Model
[0004] The utility model aims to solve at least to some extent the technical problems in the related technologies. For this purpose, the utility model provides a repair port locking mechanism, which includes a main body framework. A repair port is opened on the main body framework.

The repair port cover plate and the repair port are connected through a flipping unit, and the flipping unit can flip the repair port cover plate; Sealing strip supports are provided at both ends of the repair port, and shock-absorbing sealing strips are connected to the sealing strip supports. The shock-absorbing sealing strips provide a self-reflecting force when the cover plate is locked; A support is fixedly connected to the repair port on the side opposite to the flipping unit, and a magnetic attraction component is connected between the repair port cover plate and the support. The magnetic attraction component is a strong magnet, and the strong magnet is fixed on the support, and magnetic attraction connection is achieved when the repair port cover plate is closed.
[0005] Preferably, the flipping unit adopts a hinge hinge, and the flipping unit connects the repair port cover plate and the main body framework together by welding.
[0006] Preferably, the support is connected to the main body framework through support bolts, and the support and the strong magnet are connected through countersunk head bolts.

[0019] As Figure 1 - Figure 2 , to solve the problem that the turn lock is easily damaged, this embodiment proposes a maintenance port locking mechanism, including a main body skeleton 1. A maintenance port is opened on the main body skeleton 1. A maintenance port cover plate 28 of the same size as the maintenance port is provided on the maintenance port. The maintenance port cover plate 28 and the maintenance port are connected by a flipping unit 2. In this embodiment, the flipping unit 2 uses a hinge hinge to connect the maintenance port cover plate 28 and the main body skeleton 1, and the flipping unit 2 can flip the maintenance port cover plate 28; a connecting support 4 is fixedly connected to the maintenance port on the side opposite to the flipping unit 28. The maintenance port cover plate 28 and the support 4 are connected by a strong magnet 3 fixed on the support 4.
[0020] The support 4 is connected to the main body skeleton 1 through a support bolt 10, and the support 4 and the strong magnet 3 are connected through a countersunk head bolt 5; the strong magnet 3 is a circular countersunk hole pot magnet, and the back of the support 4 is connected to the countersunk head bolt 5 and a self-locking nut 11 is used for self-locking. To facilitate the opening of the maintenance port cover plate 28, a handle is provided at the top of the maintenance port cover plate 28.
[0021] The hole of the support 4 for fixing the strong magnet 3 is a threaded hole. When the threaded hole and the self-locking nut 11 cooperate to achieve self-locking during the installation and adjustment of the strong magnet 3, the strong magnet is allowed to have an amount of movement to achieve close fitting with the maintenance port cover plate 28.
[0022] The maintenance port cover plate in this embodiment is connected by a hinge hinge, with a simple structure. Just lift the cover plate handle to open and close the maintenance port cover plate 28.
[0023] In this embodiment, strip-shaped seal supports 7 are also provided at both ends of the maintenance port. A shock-absorbing seal 6 is connected to the seal support 7. The shock-absorbing seal 6 provides a self-reaction force for the maintenance port cover plate 28, ensuring that the maintenance port cover plate 28 is firmly and reliably attracted by the strong magnet 3, without generating abnormal noises due to vibration, reducing the entry of dust into the maintenance port and buffering at the same time, and reducing the damage probability of the locking mechanism.
[0024] Working principle: When the maintenance port cover plate 28 is closed, the strong magnet 3 is attracted to the upper part of the maintenance port to form a lock; in addition, the shock-absorbing seal 6 provides a self-reaction force to play an auxiliary locking role. When the maintenance port cover plate 28 is opened, due to the strong magnetic attraction, lift the cover plate handle to easily open the maintenance port cover plate 28. After opening to the maximum position, the flipping unit 2 blocks the lower lock, enabling maintenance personnel to perform maintenance more easily.
[0025] Although the specific implementation manners of the utility model are described above in conjunction with the drawings, it is not a limitation on the protection scope of the utility model. Based on the technical solution of the utility model, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the utility model.
