Description

Technical Field

[0001] This utility model relates to an open and close locking pointer with a fork-type structure. Background Technology

[0002] Currently, electric container spreaders are equipped with spreader indicator lights to determine whether the turnlock is in place. However, when the spreader is used for container transfer inside the factory, the lifting height is relatively low, making it impossible to accurately indicate whether the turnlock is open or closed. Utility Model Content

[0003] The technical problem to be solved by this utility model is: how to accurately determine whether the rotary lock is in place on an electric container spreader, and to provide an open and close lock pointer with a fork-type structure.

[0004] To solve the above problems, this utility model is achieved through the following technical solution: An open / close lock pointer of a fork-type structure includes a rotating shaft, with a pointer fixed to the end of the rotating shaft by bolts; a fork arm is connected to the end of the rotating shaft by a flat key, the fork arm is provided with a hole, a fork shaft is provided in the hole, and the other end of the fork shaft is welded to the connecting rod of the lock mechanism. An outer bushing is fitted around the middle of the rotating shaft, and a bearing housing is mounted on the outer bushing. A bearing is installed inside the bearing housing, which is mounted on the end beam of the rotary locking mechanism.

[0005] The bearing housing is equipped with an end cover, and the end cover is equipped with an end cover fastener.

[0006] A sealing ring and a retaining ring are provided between the outer bushing and the rotating shaft.

[0007] Compared with the prior art, the present invention has the following advantages: The present invention is installed on the side of the end beam of the container spreader's twist lock mechanism, with the pointer pointing to the open and closed lock indicators, which makes it easy to judge the position of the twist lock when used in situations where the lifting height is reduced, such as in factories.

[0009] 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.

[0010] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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 utility model.

[0011] like Figure 1 , Figure 2 As shown, an open / close lock pointer of a fork-type structure includes a rotating shaft 4, with a pointer 1 fixed to the end of the rotating shaft 4 by a bolt 2. A fork arm 13 is connected to the end of the rotating shaft 4 by a flat key. A hole 3 is provided on the fork arm 13, and a fork shaft 14 is provided in the hole 3. The other end of the fork shaft 14 is welded to the connecting rod of the lock mechanism.

[0012] During assembly, an outer bushing 8 is fitted over the middle of the rotating shaft 4, and a bearing housing 9 is installed on the outer bushing 8. A bearing 7 is installed inside the bearing housing 9. The bearing housing 9 is installed on the end beam of the rotary locking mechanism, so that the entire structure is fixed on the end beam.

[0013] Even better, the bearing housing 9 is provided with an end cover 10, and the end cover 10 is provided with an end cover fastener.

[0014] Even better, a sealing ring 5 and a retaining ring 6 are provided between the outer bushing 8 and the rotating shaft 4.

[0015] The working principle of this utility model is as follows: Pointer 1 is mounted on the end of rotating shaft 4 via bolt 2. Bearing housing 9 is fixed to the middle of rotating shaft 4 and is also mounted on the end beam of the rotary locking mechanism, thus fixing the entire structure to the end beam. Shift fork arm 13 is connected to rotating shaft 4 via a flat key. One end of shift fork shaft 14 is welded to the connecting rod of the rotary locking mechanism, and the shaft end of shift fork shaft 14 is inserted into the hole 3 of shift fork arm 13. During operation, the connecting rod of the rotary locking mechanism reciprocates, which serves as the driving force, thereby causing shift fork shaft 14 to also reciprocate. Figure 1 (Vertical to the paper direction) The shift fork shaft 14 drives the shift fork arm 13 to reciprocate within 90 degrees. Due to the reciprocating rotation of the shift fork arm 13, the rotating shaft 4 is driven to rotate 90 degrees, so that the pointer 1 points to the open / closed indicator point. It should be noted that during the rotation, the shift fork shaft 14 will slide in the hole 3.

[0016] This utility model relates to a rotary lock mechanism with a fork-type open / close pointer installed on the side. When the rotary lock mechanism rotates, the connecting rod drives the fork to rotate the pointer, which points to the open and closed indicators respectively, making it easier to judge the position of the rotary lock and playing an auxiliary judgment role.

[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
