Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of handles, and more specifically, to a flip handle with a locking function. Background Art
[0002] A handle refers to a tool for pulling or operating (opening, closing, hanging) (such as a round handle rope, cable, handle). A handle is a component installed on a door body to facilitate opening and closing the door. There are many forms and functions of handles in industrial boxes, and their quality is better than that of ordinary handles.
[0003] Currently, handles are usually installed on door panels. In industrial boxes, the common handle is a flip type. The flip handle is rotated out from the door panel in a flip manner. Under the action of gravity, it is in a closed state at the initial position (the semi-circular ring of the handle is hidden inside the door). By pressing the upper part of the handle, the handle rotates around the pin by 180°, and then the handle of the handle is exposed. At this time, the handle can be operated to pull the door. However, during the transportation of the equipment, due to vibration, most of the existing flip handles cannot maintain their initial positions, and the handles of the handles will protrude from the door surface. During the transportation of the product, the protruding handles are easily collided by other objects, resulting in damage to the handles. In addition, the shape of the flip handle is generally designed to be mirror-symmetrical, and it is easy to make mistakes in the installation direction during assembly. After assembly, there are two directions of counterclockwise flipping and clockwise flipping, resulting in poor handle function. Summary of the Utility Model

A weight limiting convex block 5 is fixedly connected to the handle body 4. Two limiting ports 6 are opened on the base 2, and the weight limiting convex block 5 matches the two limiting ports 6. An auxiliary mechanism is arranged between the handle body 4 and the base 2, and the auxiliary mechanism is used to assist the assembly between the handle body 4 and the base 2 to prevent the handle from being assembled incorrectly. A locking mechanism is arranged on the base 2, and the locking mechanism is used to limit the weight limiting convex block 5 to make the handle body 4 stable inside the base 2.
[0031] In this embodiment, the base 2 is installed on the door panel through the mounting plate 1. The handle body 4 is rotatably connected to the inside of the base 2 through the pin shaft 3. When the handle body 4 is assembled into the base 2, the auxiliary mechanism ensures the accurate installation direction of the handle body 4. After the handle body 4 is assembled with the base 2, the weight limiting convex block 5 corresponds to a limiting port 6. The weight limiting convex block 5 is restricted by the locking mechanism, so that the handle body 4 is stable in the base 2, preventing the arc handle part of the handle body 4 from protruding and colliding with other objects during the transportation of the equipment, resulting in damage. When the handle body 4 needs to be rotated out for use, by unlocking the locking mechanism, the weight limiting convex block 5 is unrestricted. The handle body 4 rotates in the base 2 through the pin shaft 3, so that the arc handle of the handle body 4 rotates out of the base 2. The weight limiting convex block 5 rotates into another limiting port 6 to keep the rotated handle body 4 stable, thus facilitating the staff to open and close the door panel.
[0032] Specifically, the auxiliary mechanism includes a positioning boss 71 and a handle groove 72. The positioning boss 71 is fixedly connected to the inside of the base 2, and the pin shaft 3 passes through the positioning boss 71. The handle groove 72 is opened on the handle body 4 and corresponds to the positioning boss 71.
[0033] In this embodiment, the handle body 4 is rotatably installed in the base 2 through the pin shaft 3, so that the handle groove 72 corresponds to the positioning boss 71. The handle body 4 is kept in the correct installation direction through the handle groove 72 and the positioning boss 71.
[0034] Specifically, the locking mechanism includes a lock case 81, a lock core 82, a lock tongue 83, a first screw 84, a positioning groove 85, a saddle washer 86 and a washer boss 87. The lock case 81 is fixedly connected to the base 2 and penetrates through the mounting plate 1. The lock core 82 is arranged in the lock case 81. The lock tongue 83 is detachably connected to one end of the lock core 82, and the lock tongue 83 is located on one side of the lock case 81 and corresponds to the weight limiting convex block 5. The first screw 84 penetrates through the lock tongue 83 and the lock case 81 and is threadedly connected to the lock core 82. The positioning groove 85 is opened on the bottom wall of the lock case 81. The saddle washer 86 is sleeved on the outer surface of the lock core 82. The washer boss 87 is arranged on the saddle washer 86 and matches the positioning groove 85.
[0035] In this embodiment, the bolt 83 is connected to one end of the lock core 82 through the first screw 84, corresponding to the counterweight limit convex block 5. The washer boss 87 on the saddle washer 86 is elastically clamped in the positioning groove 85. By turning the lock core 82 with the key, the lock core 82 drives the saddle washer 86 to rotate within the lock shell 81. When the washer boss 87 on the saddle washer 86 leaves the positioning groove 85 in the lock shell 81, the saddle washer 86 is compressed by a certain distance. After rotating 90°, the washer boss 87 is elastically clamped in the positioning groove 85 again, and the compression amount of the saddle washer 86 is released, so as to obtain a real sense of in-place. At the same time, the rotation of the lock core 82 drives the bolt 83, and the bolt 83 rotates within a range of 90°, which can restrict and cancel the restriction on the counterweight limit convex block 5, thereby controlling the rotation of the handle body 4.
[0036] Specifically, a positioning port 9 is provided on the inner surface of the saddle washer 86, and a positioning convex block 10 is fixedly connected to the outer surface of the lock core 82, and the positioning convex block 10 is located within the positioning port 9.
[0037] In this embodiment, the saddle washer 86 is sleeved on the lock core 82 through the clamping of the positioning port 9 and the positioning convex block 10, realizing the rotation of the lock core 82 to the saddle washer 86.
[0038] Specifically, a gasket 11 is sleeved on the outer surface of the first screw 84, and the gasket 11 corresponds to the bolt 83.
[0039] In this embodiment, the gasket 11 is arranged between the first screw 84 and the bolt 83, increasing the contact area, reducing the pressure, preventing loosening, and protecting the first screw 84 and the bolt 83.
[0040] Specifically, a switch mark 12 is provided on the base 2, and the switch mark 12 corresponds to the lock core 82.
[0041] In this embodiment, it is convenient to confirm the rotation angle of the lock core 82 through the switch mark 12, so as to determine the rotation position of the bolt 83.
[0042] Specifically, two pressure feet 13 are fixedly connected to the mounting plate 1, and two connecting blocks 14 are fixedly connected to the base 2. The two connecting blocks 14 penetrate through the mounting plate 1 and are respectively located within the two pressure feet 13. Second screws 15 are threadedly connected between the two pressure feet 13 and the two connecting blocks 14 respectively.
[0043] In this embodiment, the two pressure feet 13 and the two connecting blocks 14 are connected through the two second screws 15, improving the connection strength between the mounting plate 1 and the base 2, and stably installing the mounting plate 1 and the base 2 on the door panel.
[0044] Working principle: The locking tongue 83 restricts the counterweight limiting convex block 5 in the lower limiting port 6, keeping the handle body 4 stable and preventing the handle body 4 from rotating out of the base 2 due to vibration and colliding with other objects. When the handle body 4 needs to be rotated out for use, the key is used to rotate the lock core 82. The lock core 82 drives the saddle washer 86 to rotate in the lock housing 81. After the washer boss 87 on the saddle washer 86 leaves the positioning groove 85 in the lock housing 81, the saddle washer 86 is compressed by a certain distance. After rotating 90°, the washer boss 87 is elastically clamped in the positioning groove 85 again, and the compression amount of the saddle washer 86 is released, so as to obtain a real sense of being in place, thereby determining that the lock core 82 drives the locking tongue 83 to rotate 90°, canceling the restriction on the counterweight limiting convex block 5. Then, press the lower part of the handle body 4, so that the handle body 4 rotates in the base 2 through the pin shaft 3. After the handle body 4 rotates 180°, the counterweight limiting convex block 5 is located in the upper limiting port 6. At this time, the arc handle of the handle body 4 rotates out of the base 2, and the staff opens and closes the door panel through the arc handle of the handle body 4.
[0045] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacement or change, and should be covered by the protection scope of the present invention.
