Description

Technical Field

[0001] The utility model relates to the technical field of one-way devices, in particular to an anti-dropping shell for a one-way device. Background Art

[0002] The starter isolator is an important component in the automobile starter. Its function is to protect the engine and prevent the engine from being damaged due to the starter turning over. During the use of the existing isolator, its shell is mostly fixedly connected to the isolator by screws or a snap-fit ​​structure. This connection method is prone to loosening of the shell after long-term use, and the loose shell is difficult to reset itself, causing the shell to fall off easily, thus affecting the normal use of the isolator. To this end, we propose an anti-falling shell for the isolator. Utility Model Content

[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0018] As attached Figure 1-4 The anti-falling shell for a one-way device shown in the figure comprises a one-way device 1, a receiving groove 2 is provided in the middle of the outer surface of the one-way device 1, extrusion protrusions 3 are provided at both ends of the middle of the inner surface of the one-way device 1 passing through the receiving groove 2, an inner shell 6 is sleeved and installed in the middle of the outer surface of the one-way device 1, a positioning groove 7 is provided in the middle of the outer surface of the inner shell 6, and docking blocks 8 are inserted through both sides of the middle of the inner surface of the inner shell 6 passing through the positioning groove 7. The docking blocks 8 are rubber blocks, and the rear end of the docking blocks 8 is arranged in a clockwise inclined shape and embedded in the receiving groove 2. A limit plate 4 is paved and installed on the lower surface of the inner shell 6, and the limit plate 4 is sleeved and connected with the outer surface of the one-way device 1. The limit plate 4 is made of an iron sheet structure, and a limit opening 5 is provided at the front end of the outer ring surface of the limit plate 4. An opening is provided at the lower front end of the outer surface of the positioning groove 7, and the opening size of the positioning groove 7 is equal to the opening size of the limit opening 5.

[0019] The outer surface of the inner shell 6 is sleeved with the outer shell 9, and the middle parts of both sides of the outer surface of the outer shell 9 are provided with limit blocks 10, and the middle part of the inner side surface of the limit block 10 is provided with a docking port 11, and the docking port 11 is aligned with the docking block 8. A protruding positioning block 12 is provided in the middle part of the front end of the inner surface of the outer shell 9. The positioning block 12 is a rubber block, and the size of the positioning block 12 is equal to the opening size of the positioning groove 7.

[0020] When working, first, the inner shell 6 can be sleeved to the outer surface of the one-way device 1, and the open end of the positioning groove 7 is aligned with the limiting opening 5 opened on the upper surface of the limiting plate 4, and at the same time, the docking block 8 is aligned with the receiving groove 2 opened in the middle part of the outer surface of the one-way device 1. At this time, the rear end of the docking block 8 will be embedded in the receiving groove 2 so that its front end is retracted into the positioning groove 7. In this case, the outer shell 9 can be sleeved and installed on the outer surface of the inner shell 6. When sleeved and installed, the positioning block 12 needs to be inserted into the positioning groove 7 opened on the outer surface of the inner shell 6 along the limiting opening 5 opened on the limiting plate 4. At this time, the outer shell 9 is sleeved and installed on the outer surface of the inner shell 6. The docking port 11 opened on the side of the limit block 10 connected to the shell 9 will be aligned with the front end of the docking block 8. In this case, it is only necessary to manually control the inner shell 6 to be in a fixed state and turn the one-way device 1 to rotate. During the rotation of the one-way device 1, the extrusion protrusion 3 set in the middle of its outer surface can squeeze the docking block 8 whose rear end is embedded in the receiving groove 2. At this time, when the rear end of the docking block 8 is squeezed, its front end can extend outward from the positioning groove 7 and be embedded in the docking port 11 opened on the limit block 10, thereby completing the connection and installation between the inner shell 6 and the outer shell 9.

[0021] When the inner shell 6 and the outer shell 9 are connected and installed, the inner shell 6 and the starter can be fixedly installed and connected. When the inner shell 6 is in a fixedly connected state, when the outer shell 9 becomes loose during long-term operation, the front end of the docking block 8 will gradually extend inward from the docking port 11, causing its rear end to extend toward the direction of the one-way device 1. At this time, the one-way device 1 can be continuously rotated to control the extrusion protrusion 3 to press the inwardly extending docking block 8. At this time, the rear end of the docking block 8 will extend its front end toward the docking port 11 again under the condition of being squeezed, thereby completing the self-reset and maintaining the installation connection stability between the inner shell 6 and the outer shell 9, which is conducive to avoiding the problem of loosening and falling off of the outer shell during long-term use, thereby avoiding the normal use of the one-way device 1 from being affected.

[0022] In summary: when this anti-fall-off housing is installed and connected to the one-way device, it can reset itself when it becomes loose, thereby keeping the housing in a stable installation state, which is helpful to avoid the problem of loosening and falling of the housing during long-term use.

[0023] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
