Description

Technical Field

[0001] The present application relates to the technical field of locking structures, and in particular to a valve locking device. Background Art

[0002] The valve of a gas cylinder is a key component that controls the flow of gas in and out. It is responsible for opening or closing the gas path of the gas cylinder. The valve is usually located at the top of the gas cylinder.

[0003] For example, the release mechanism on the life raft cylinder. As an onboard emergency life-saving device, the inflation system of the life raft is mostly powered by the cylinder. The release mechanism of the gas in the cylinder mainly includes a spherical valve core installed inside the cylinder valve, an external drive pulley and a steel cable, etc. The spherical valve core is provided with an air outlet channel, which is not connected to the inside of the cylinder under normal circumstances. When the drive pulley rotates under the action of the release cable, the drive pulley drives the spherical valve core to rotate, so that the air outlet channel is connected to the inside of the cylinder, and the gas in the cylinder is released.

[0004] However, due to the lack of a pulley locking device, the release cable can be easily pulled by external force, causing the gas cylinder to be accidentally released, so this release mechanism has the risk of misoperation.

[0005] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0006] The purpose of this application is to reduce the risk of the gas cylinder valve being opened by mistake.

[0007] The above technical purpose of the present application is achieved through the following technical solutions: a valve locking device, including a limit column for being plugged into a valve; and also including a locking beam, the locking beam is provided with a mounting groove, the bottom of the mounting groove is hollowly arranged to form a first mounting channel, the limit column is provided with a mounting rod, the mounting rod passes through the locking beam through the first mounting channel, the locking beam can slide relative to the mounting rod, the mounting rod is provided with a fastener, the fastener cooperates with the limit column to clamp the locking beam, so that the locking beam is installed and embedded on the valve through the mounting groove, the bottom of the mounting groove is fixedly provided with a locking plate, and the locking plate is provided with a limit hole.

[0008] By adopting the above technical solution, through the design of the locking beam and the limiting column, the locking plate is fixedly installed on the valve, and the installation and locking of the valve becomes simple and easy, and the operator can easily assemble and lock it; the locking beam and the limiting column are stable and reliable, which can ensure that the valve is not easily disturbed or damaged by external forces in the locked state, thereby extending the service life of the valve and reducing the possibility of misoperation. The locking plate limits the movement of the installation pin and the rotation and opening and closing of the valve rotating structure by fitting the limiting hole on the locking plate. The valve can be effectively locked to prevent accidental operation from opening the valve, thereby improving the safety of valve use.

[0009] Optionally, a snap-on piece is provided on the locking plate.

[0010] By adopting the above technical solution, the clamping piece can be embedded in the clamping groove on the valve, and the position of the locking beam can be located, so that the locking beam can be accurately and stably installed on the valve. The clamping piece can provide an additional fixing point, so that the connection between the locking plate and the valve fixing structure is more secure, and the possibility of the valve rotating structure rotating relative to the valve fixing structure is reduced.

[0011] Optionally, an engaging groove is recessed in the wall of the installation groove.

[0012] By adopting the above technical solution, the fitting groove can fit the shape of the valve, so that the locking beam and the valve can fit more closely and form a more precise fit. The optimized installation fit can ensure a stronger connection between the locking device and the valve, and improve the stability and reliability of the entire device.

[0013] Optionally, the fitting groove is hollow to form a second installation channel, an inner wall of the second installation channel is provided with an internal thread, a bolt is provided in the second installation channel, and the bolt can abut against or separate the valve.

[0014] By adopting the above technical solution, the valve is abutted by bolts, which increases the stability of the locking beam set on the valve, reduces the possibility of the locking beam being easily deflected or even falling off due to external forces, and improves the stability of the locking device.

[0015] Optionally, a threaded structure is provided on the mounting rod, a third mounting channel is hollowly provided in the fastener, a threaded structure is provided in the third mounting channel, and the relative position of the fastener on the mounting rod is adjusted by turning the fastener.

[0016] By adopting the above technical solution, the threaded structure on the mounting rod and the design of the fastener allow the fastener to move freely on the mounting rod. The mounting rod can be separated by disassembling the fastener, so that the locking beam can be installed on the limit column through the mounting rod. After the locking beam is installed, the position of the fastener on the mounting rod is adjusted to fix the locking beam and fit it on the valve.

[0017] Optionally, the fastener is provided with a holding piece, and the holding piece is provided with a ridge.

[0018] By adopting the above technical solution, the design of the grip allows the operator to easily grip the fastener and perform rotational adjustment. The presence of the ridges provides additional gripping force and friction, making the operation more stable and less prone to sliding, thereby improving the comfort and safety of the operation. Due to the presence of the grip, the operator can more easily adjust the position of the fastener without the need for additional tools or equipment. This convenient design saves operating time and labor costs and improves operating efficiency. The ridge design of the grip increases the wear resistance and durability of the fastener and reduces wear and damage caused by long-term use. This can extend the service life of the locking device and reduce maintenance and replacement costs.

[0019] In summary, this application has at least the following beneficial effects:

[0020] 1. Through the design of the locking beam and the limit column, the locking plate is fixedly installed on the valve, and the installation and locking of the valve becomes simple and easy. The operator can easily assemble and lock it; the locking beam and the limit column are stable and reliable, which can ensure that the valve is not easily disturbed or damaged by external forces in the locked state, thereby extending the service life of the valve and reducing the possibility of misoperation. The locking plate limits the movement of the installation pin and the opening and closing of the valve rotating structure through the limit hole on the locking plate. The valve can be effectively locked to prevent accidental operation from opening the valve, thereby improving the safety of valve use.

[0021] 2. The clamping piece can be inserted into the slot on the valve to locate the position of the locking beam, so that the locking beam can be accurately and stably installed on the valve. The clamping piece can provide an additional fixing point to make the connection between the locking plate and the valve fixing structure more secure, reducing the possibility of the valve rotating structure rotating relative to the valve fixing structure.

[0022] 3. Bolts are used to abut the valve to increase the stability of the locking beam on the valve, reduce the possibility of the locking beam being easily deflected or even falling off due to external forces, and improve the stability of the locking device. BRIEF DESCRIPTION OF THE DRAWINGS
