Abstract

The utility model relates to a protecting cover structure of a cylinder valve, which belongs to machinery. The protecting device of a cylinder valve is sleeved on an exhaust valve of a gas cylinder and is mainly formed by a casing and a seat, wherein the casing forms a holding space, a peripheral wall of the casing forms a corresponding through hole, a locking portion is arranged inside the peripheral wall, the casing and a fixing portion of the seat can be mutually locked by using the locking portion, and additionally, a plurality of positioning components in position correspondence are arranged at predetermined positions of the fixing portion. Accordingly, after the casing and the seat are mutually locked and combined, not only position of the protecting cover device mounted on the gas cylinder can be fixed, further, damage on the exhaust valve caused by being collided by articles can be avoided, but also the protecting cover device has the advantages of improved convenience in assembly and disassembly and prevention of damage on the exhaust valve caused by being collided by the articles.

Description

The holding protective cover device of cylinder valve

Technical field

The utility model relates to mechanical, and particularly a kind of holding protective cover device of cylinder valve refers to a kind of holding protective cover device that promotes the global design sense and be more conducive to the cylinder valve of dismounting protective cover especially.

Background technique

Progress along with industrial technology; make the design level of industry also promote relatively; but the manufacture of industry is the basis according to basic manufacturing mode still; for example: industrial processes factory; industry manufactory etc.; all need utilize gas cylinder to store required gas; and apply on the workpiece of required processing; by gas cylinder gas is fills up in the bottle after via high pressure compressed; therefore gas cylinder must utilize drain tap to control the output quantity of internal gas; therefore drain tap can directly have influence on the industrial safety of factory; therefore being subjected to external force for fear of drain tap causes damage, generally all can install protective cover, with the protection drain tap.

Yet above-mentioned protection is placed on when using, and still exists following point to wait to improve:

1, this kind protective cover utilizes metal to cast, and directly is set on the drain tap, owing to can't directly lock between protective cover and the drain tap, and therefore when transporting gas cylinder and effectively fixing protective cover and then cause disengaging.

2, because of the state of protective cover, allow protective cover directly clash into drain tap so be vulnerable to rock, and then cause the damage of drain tap for becoming flexible.

The model utility content

The purpose of this utility model is to provide a kind of holding protective cover device of cylinder valve, solves existing protective cover effectively fixing protective cover and then cause the problem of disengaging when transporting gas cylinder; And, be vulnerable to rock and allow protective cover directly clash into drain tap, and then cause the problem of the damage of drain tap because of protective cover is loosening state.

A kind of holding protective cover device of cylinder valve, this holding protective cover device is with the valve of sheathed gas cylinder, and it comprises:

One cover body, this cover body has a perisporium, and this perisporium is provided with a containing space, forms corresponding perforation on this perisporium, is provided with a locking part in this perisporium inboard in addition; And

One pedestal, this pedestal forms a logical portion that communicates with this containing space, and this pedestal is provided with one and the fixing part that locks mutually of this locking part, and is provided with the corresponding locating piece in plural position in the precalculated position of this fixing part.

Wherein this pedestal forms to lock mutually with this gas cylinder in inner face and flies screw thread;

Wherein this cover body and this pedestal further can be formed in one.

Advantage of the present utility model is: after cover body and pedestal lock combination mutually, holding protective cover device is installed on the gas cylinder, the fixing position of holding protective cover device, and then can prevent drain tap to be subjected to the collision of object and damage the convenience in the time of also being increased in assembling or dismounting.

Embodiment

As accompanying drawing 1 to shown in the accompanying drawing 3, schematic perspective view for the utility model preferred embodiment, the local enlarged diagram of perspective exploded view and pedestal, find out that by knowing among the figure the utility model is a kind of holding protective cover device of cylinder valve, this holding protective cover device 1 is in the drain tap 20 of sheathed gas cylinder 2, its holding protective cover device 1 mainly is made up of cover body 10 and pedestal 12, wherein cover body 10 has a perisporium 101, and this perisporium 101 is provided with a containing space 102, and form corresponding perforation 104 in the perisporium 101 of cover body 10, be provided with a locking part 106 in perisporium 101 inboards in addition, utilize this locking part 106 to lock mutually with the fixing part 120 of pedestal 12, in addition, fixing part 120 is provided with in the precalculated position and the corresponding locating piece 122 in plural position.

Because pedestal 12 inner faces form first screw thread 124, and also form second screw thread 22 with the 124 corresponding lockings of first screw thread on the gas cylinder 2, pedestal 12 can be locked on the gas cylinder 2.

By above-mentioned structure, form design, be described as follows with regard to use situation of the present utility model, as shown in Figure 4, user mode generalized section for the utility model preferred embodiment, find out by knowing among the figure, at first, pedestal 12 is locked in second screw thread 22 on the gas cylinder 2 by first screw thread 124, then utilize the locating piece 122 on the fixing part 120 of being located at pedestal 12 further pedestal 12 to be locked on the gas cylinder 2 securely again, after finishing pedestal 12 fixing, cover body 10 is interfixed by the fixing part 120 of locking part 106 with pedestal 12, thus, when cover body 10 locks combination mutually with pedestal 12 after, then holding protective cover device 1 is installed on the gas cylinder 2, the fixing position of holding protective cover device 1, and then can prevent drain tap 20 to be subjected to the collision of object and damage.

As shown in Figure 5, action schematic representation for the utility model utilization iron turn-off holding protective cover device, owing to form corresponding perforation 104 on the cover body 10, therefore work as holding protective cover device 1 Ka Detai and tightly can't utilize the hand rotating opening, or holding protective cover device 1 gets rusty and causes when stuck, and available iron bar 3 penetrates in the perforation 104, also can easily holding protective cover device 1 be opened in the mode of lever principle, so, need not to worry that holding protective cover device 1 can't open to cause the problem of construction inconvenience.

As shown in Figure 6, schematic representation for another embodiment of the utility model, when making holding protective cover device 1a, can be with cover body 10a and pedestal 12a as one-body molded, the time utilize the first screw thread 124a on the pedestal 12a to be locked in the second screw thread 22a on the gas cylinder 2a in assembling, mode with spiral makes holding protective cover device 1a reach the purpose that is fixed on the gas cylinder 2a, the convenience when using this kind mode also can be lifted at assembling and dismounting.
