Description
Technical Field
[0001] The utility model discloses a valve body structure with a switch display function, which particularly relates to a technology applied in the field of gas. Background Art
[0002] Nowadays, the most common gas used in homes is gas cylinders and natural gas. This type of energy is highly dangerous, so a switch device must be used to control the conduction of the gas. In fact, this is not only true for gas, but also for water energy. In order to avoid unnecessary waste, the conduction of water energy is also controlled by the installation of a switch device. What we are going to discuss now is that in the use of gas, most gas cylinders are placed outdoors. The main reason is safety needs, but one thing is overlooked, that is, it is difficult for users to identify the opening and closing of the switch device.
[0003] Normally, users judge the switch device as being closed clockwise and open counterclockwise, so they have to repeatedly operate the switch left and right each time to know whether the switch device is open or closed. Over time, the switch device knob and the valve body are prone to loosening, and when children do not understand the direction of the switch and turn it randomly, it will be dangerous. In addition, for young children, the elderly, people with limited mobility or vision, these types of users will also have some inconvenience in operation. In addition, some switch devices are located in places where they cannot be seen, and they are operated entirely by the user's feel. These practices all have certain risks. Utility Model Content

DETAILED DESCRIPTION
[0027] Please see Figures 1 to 8As shown, the utility model is a valve body structure with a switch display function, which includes: a valve body 1, which has a mounting portion 11 located at the top, an input portion 13 and an output portion 14 located on the left and right sides of the valve body 1, and a fuel inlet portion 15 located at the bottom of the valve body 1, the fuel inlet portion 15 can be connected to a gas tank or a natural gas pipe, the input portion 13 is installed for a safety valve (not shown), and the output portion 14 is connected to a place where gas is needed (such as a stove, a water heater, etc.) for supply. The input portion 13, the output portion 14 and The fuel inlet 15 is mutually conductive, and a control component 2 is provided at the mounting portion 11. The control component 2 is partially buried in the mounting portion 11, and the control component 2 is partially exposed outside the mounting portion 11 to form a detent platform 21. The control component 2 limits and controls the conduction and closure between the input portion 13 and the output portion 14; a valve button 3 is set on the portion of the control component 2 protruding from the mounting portion 11, and a plurality of finger grooves 31 are concavely arranged around the outer circumference of the valve button 3 to provide each finger of the hand for gripping and control, and the rotation control of the valve button 3 The control component 2 controls the conduction and closure between the fuel inlet portion 15 and the output portion 14, and the valve button 3 sets the position of the control component 2 through a combination hole 32, the protruding part of the control component 2 is inserted from the bottom end of the combination hole 32, and a screw 4 is inserted from the top end of the combination hole 32 and locked to the control component 2; and an identification member 5, which is movably assembled in a combination hole 33 of the valve button 3, and the combination hole 33 passes through the top and bottom ends of the valve button 3. The identification member 5 includes an identification portion 51 and a detent portion 52. The detent portion One end of 52 is connected to the bottom surface of the identification portion 51, and the other end of the detent portion 52 passes through the combination hole 33 and normally abuts against the actuating platform 12. The rotation of the valve button 3 controls the displacement of the identification member 5. When the valve button 3 rotates and approaches the valve body 1, the detent portion 52 of the identification member 5 abuts against the actuating platform 12 to make the identification portion 51 protrude from the orifice of the combination hole 33. When the valve button 3 rotates and moves away from the valve body 1, the identification member 5 gradually sinks into the combination hole 33 to make the identification portion 51 located in the combination hole 33.
[0028] According to the above description, if the installation place of the utility model is a dark place, a place with poor visibility, or it is impossible for users (including people with limited mobility and the elderly) to directly identify whether to open or close by visual means, the user only needs to rotate the valve knob 3 under normal switch operation. As long as the identification portion 51 of the identification member 5 protrudes from the combination hole 33, the user will touch the protruding part of the identification portion 51 during the operation, so that the user can know that the rotation direction is the closing operation; conversely, as long as the identification portion 51 that cannot be touched during the rotation of the valve knob 3 is convex, then the control direction can be determined to be the opening operation; and similarly, if in the relevant The location can be judged visually, which is more convenient for the user. The user can directly visually observe whether the identification portion 51 is convex or concave relative to the combination hole 33. In this way, it can be quickly and easily determined whether the current control component 2 conducts the fuel inlet portion 15 and the output portion 14, or blocks the conduction between the fuel inlet portion 15 and the output portion 14. Regardless of the location and position where the utility model is installed, it is easier for the user to determine the opening and closing operation direction of the valve button 3 without misjudgment. This can avoid possible dangers caused by misjudgment and maintain the service life of the valve button 3 and the control component 2.

First, please see Figures 4 to 8As shown, the utility model is specially designed in the identification part 51 of the identification member 5, which is mainly to provide the user with a more direct way to determine the direction under visual identification, so the identification part 51 of the identification member is further divided into a direction identification area 511 and a switch identification area 512, the direction identification area 511 is provided with an arrow identification end 5111 and a text identification image 5112 engraved on the top surface of the direction identification area 511 at one end, and the switch identification area 512 is engraved with a text judgment image 5121 on the top surface, and the design of the arrow identification end 5111 allows the user to directly determine whether the rotation direction is open or closed, and the protrusion and indentation of the identification part 51 relative to the combination hole 33 can be more accurately controlled to prevent the problem of misjudgment and wrong rotation direction, and the setting of the text recognition image 5112 and the text judgment image 5121 provides the user with a touch method. The direction in which the valve button 3 is to be rotated is to open or close; in addition, in order to cooperate with the structural feature design of the identification piece 5, the design of the combination hole 33 must also cooperate with the shape of the identification portion 51 of the identification piece 5, so the combination hole 33 is further divided into a first hole area 331 and a second hole area 332, the first hole area 331 and the second hole area 332 are connected, and the hole shape of the first hole area 331 corresponds to the shape of the direction identification area 511, which is an arc-shaped arrow hole shape, and the second hole area 332 corresponds to the shape of the switch identification area 512, which is a round hole shape. In addition, a retaining rib 34 is extended in opposite directions from the two side walls where the first hole area 331 and the second hole area 332 are connected, and each retaining rib 34 is installed to separate the direction identification area 511 and the switch identification area 512, and the setting of each retaining rib 34 is mainly to prevent foreign matter from entering the combination hole 33 and affecting the actuation of the identification piece 5, please see Figure 4 shown.
[0030] Continuing with the above description, in order to prevent the identification member 5 from falling out of the combination hole 33 when the valve button 3 rotates away from the detent platform 12, a limiting portion 35 is further formed at the connection between the first hole area 331 and the second hole area 332 and at the bottom end of each blocking rib 34. When the valve button 3 gradually rotates away from the detent platform 12, the identification portion 51 of the identification member 5 gradually sinks into the combination hole 33, and the connection between the identification portion 51 and the detent portion 52 abuts against the limiting portion 35, see FIG.

The section groove 521 is set by the bottom end face of the detent portion 52 toward the end connected to the identification portion 51, and the guide cone annular surface 53 is formed on the outer peripheral surface of the detent portion 52. In addition, a limiting rib 36 is arranged around the inner wall of the combination hole 33. The setting of the limiting rib 36 limits part of the aperture of the combination hole 33. After the detent portion 52 of the identification piece 5 is inserted into the combination hole 33 and the guide cone annular surface 53 is pressed against the limiting rib 36, the detent portion 52 is elastically deformed and retracted due to the setting of the slot 521, so that the detent portion 52 can pass through the limiting rib 36 and then elastically return to its original position and be stopped by the limiting rib 36, thereby preventing the entire identification piece 5 from falling out of the combination hole 33; in addition, a protruding stop portion 54 is formed at the position where the guide cone annular surface 53 is provided on the detent portion 52, and the stop portion 54 is mainly used to prevent the identification piece 5 from falling out of the combination hole 33. In order to prevent the identification member 5 from being affected by foreign matter during the long-term operation between the identification member 5 and the valve button 3, so that the identification member 5 cannot operate smoothly, a spring 7 is further provided on the detent portion 52 of the identification member 5. One end of the spring 7 is elastically pressed against the limiting rib 36, and the other end of the spring 7 is elastically pressed against a stop portion 54 protruding from the detent portion 52. The guide cone annular surface 53 is connected to the edge of the stop portion 54. In short, through the setting of the spring 7, the identification portion 51 of the identification member 5 will normally be protruding from the combination hole 33. However, if there is a foreign object between the detent portion 52 and the limiting rib 36, the identification portion 51 of the identification member 5 cannot sink into the combination hole 33 during the process of the valve button 3 from closing to opening, and moves upward with the valve button 3, so that the user cannot identify whether it is open or closed. Therefore, the spring 7 is set to elastically drive the identification portion 51 of the identification member 5 to sink into the combination hole 33, so that the user can clearly judge the difference between opening and closing. Figures 9 to 11 shown.
[0032] In addition, in order to provide a reliable combination in the assembly of the valve button 3 and the control component 2, the combination hole 32 is further divided into an upper hole section 321, a lower hole section 322 and a partition rib 323 between the upper hole section 321 and the lower hole section 322. The hole diameter of the upper hole section 321 is larger than the hole diameter of the lower hole section 322, and the upper hole section 321 is connected to the combination hole 33. In addition, the partition rib 323 is located on an end surface of the upper hole section 321 and further convexly has a plurality of anti-slip ribs 324. The screw 4 is inserted into the combination hole 32 and locked with the control component 2 to abut against each anti-slip rib 324. 4, and the control component 2 is partially inserted into the lower hole section 322 and abuts against the partition rib 323. The partition rib 323 is provided to not only allow the screw 4 to sink into the upper hole section 321 of the combination hole 32 without being exposed, but also to prevent the screw 4 and the control component 2 from colliding with each other and wearing when the valve button 3 rotates. In addition, the provision of each anti-slip rib 324 can also provide that if a gasket 6 is to be placed between the upper hole section 321 and the partition rib 323 (the figure mainly shows the gasket 6), the rotation of the gasket 6 can be prevented, because the contact between the gasket 6 and each anti-slip rib 324 will generate friction, and the gasket 6 is made of rubber, please see Figures 4 to 8 shown.
[0033] Finally, the utility model further provides an adjustment slot 41 at the top of the screw 4. The adjustment slot 41 is in the form of a straight slot, a cross slot (not shown) or a pound-shaped slot (not shown).
