Description

Technical Field

[0001] The utility model relates to the technical field of joystick mechanisms, in particular to a mechanism for locking a joystick of a multi-way valve at any position on a control table. Background Art

[0002] When a ship is sailing on the ocean, the staff often uses the multi-way valve stem to control the various work processes of the ship. The multi-way valve stems installed on some existing ship control panels lack the friction positioning function when in use, which leads to great difficulties for the staff if they want to lock the valve stem at any position within its motion range. The multi-way valve stem is prone to deviation without the adjustment of external fixed traction, which not only causes certain inconvenience to the staff but also poses certain safety hazards.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-3As shown, a mechanism for locking a multi-way valve operating lever at any position on a control panel comprises a positioning seat 1, through which the device can be fixed as a whole on the control panel of a ship, thereby ensuring the overall stability of the device during operation, and at the same time, it also provides an installation position for other structures, two groups of erection side plates 2 are symmetrically connected near the edge of the top of the positioning seat 1, and a limiting sleeve 3 is connected between the erection side plates 2, and the erection side plates 2 are erected and fixed to the limiting sleeve 3 by bolts, thereby ensuring the stability of the limiting sleeve 3, and the limiting sleeve 3 can be used to limit the traction rod body 5, thereby ensuring that the traction rod body 5 can move smoothly, a support seat 4 is connected to the front of the limiting sleeve 3, a groove body is provided on the top of the support seat 4, and a traction rod body 5 is arranged inside the groove body, one end of the traction rod body 5 passes through the interior of the limiting sleeve 3 and is connected to a hinged rod plug 6, one end of the hinged rod plug 6 is rotatably connected to a valve stem sleeve 7, and a positioning threaded hole is provided on one side of the valve stem sleeve 7 for installing bolts to position the valve stem sleeve 7 on the control rod.

[0021] A follower pressure block 8 is arranged inside the groove body above the traction rod body 5. The shape of the follower pressure block 8 is U-shaped. An interlocking groove is provided at the bottom of the follower pressure block 8. The shape of the interlocking groove is V-shaped or U-shaped. When the follower pressure block 8 presses the traction rod body 5 downward, the traction rod body 5 is fixed to prevent the traction rod body 5 from moving. When the interlocking groove is V-shaped, the pressure of the inner wall of the follower pressure block 8 on the traction rod body 5 is effectively increased, and the firmness of the fixation is further improved. When the interlocking groove is U-shaped, it can be completely fitted on the traction rod body 5 to avoid excessive pressure causing deformation of the traction rod body 5.

[0022] A top plate 9 is connected to the top of the support seat 4, and the outer side of the top plate 9 is in contact with the top inner wall of the follower pressure block 8. An adjustment handle 10 is provided on the top of the top plate 9, and the bottom end of the adjustment handle 10 passes through the top of the top plate 9 and is rotatably connected to the top of the follower pressure block 8.

[0023] By sleeve-connecting the valve stem sleeve 7 to the joystick on the ship's operating console and then fixing the two with bolts, when the joystick is moved to the ideal position, the staff can rotate the adjusting handle 10 to make the follower pressure block 8 move downward, and use the engaging groove at the bottom of the follower pressure block 8 to engage with the traction rod body 5, thereby achieving the fixation of the traction rod body 5. The joystick is fixed by connecting one end of the traction rod body 5 with the valve stem sleeve 7, ensuring that the joystick can be fixed in one position for a long time without displacement or resetting.

[0024] The working principle of the utility model is as follows: the device can be fixed on the ship's operating table as a whole through the positioning seat 1, and then the valve stem sleeve 7 is sleeved on the joystick on the ship's operating table. When the staff moves the joystick to a predetermined position, the rotating adjustment handle 10 drives the follower pressure block 8 to move downward, and the follower pressure block 8 squeezes and fixes the traction rod body 5, thereby forming a fixed traction on the joystick to ensure its position is fixed.

[0025] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
