[0002] A gas riser refers to a pipeline for transporting gas in a heat pipe network, and is widely used in many fields such as urban heating and industrial production. It is usually made of high-quality steel or stainless steel materials, and has good corrosion resistance and high temperature resistance in a high temperature and high pressure environment. When the gas riser is damaged and needs to be repaired, during the repair, it is often encountered that the main pipeline leaks gas and it is necessary to close the valves on one floor or in sections.

[0003] However, there are some problems in the prior art: most users on one floor and in sections have the main pipeline enclosed or the reserved space in the cabinet is small, and the valve cannot be closed. When it is necessary to inform the user to remove the cabinet, the user refuses to cooperate or it takes a certain amount of time to remove the cabinet. In this case, the gas use safety of the users upstairs cannot be guaranteed. And when the cabinet cannot be restored after being removed on site, the subsequent work is more cumbersome, and it is necessary for the property and the community to negotiate with the user in multiple aspects, and there is a situation where the negotiation fails, which has certain limitations.

Detailed Description of the Preferred Embodiment

[0024] In order to further understand the content, features and effects of the present utility model, the following embodiments are cited and described in detail with reference to the accompanying drawings as follows.

[0025] As Figures 1 to 6 shown, the gas riser lengthened sleeve switch provided by the embodiment of the present utility model includes: a wrench 1, a sleeve docking assembly 5 and an extension assembly 6. A transmission mechanism 7 is provided at the upper end of the wrench 1. The upper end of the wrench 1 is rotationally connected to a lengthened base 2 through the transmission mechanism 7. A lengthened sleeve 4 is provided at one end of the lengthened base 2.

[0026] By providing the lengthened base 2 and the lengthened sleeve 4, the working range of the wrench 1 can be extended, and it can be used for cases where the main pipeline is enclosed or the reserved space in the cabinet is small and the valve cannot be closed, thereby improving the practicability of the wrench 1.

[0027] The sleeve docking assembly 5 is slidably sleeved outside the lengthened sleeve 4. One end of the lengthened sleeve 4 is detachably connected to a valve sleeve 3 through the sleeve docking assembly 5.

[0028] The extension component 6 is arranged at one end of the extension sleeve 4, and the sleeve docking component 5 is movably connected to the extension component 6. The sleeve docking component 5 approaches or moves away from the wrench 1 through the extension component 6.

[0029] As Figures 1 to 6 shown, due to the design that the sleeve docking component 5 approaches or moves away from the wrench 1 through the extension component 6, the sleeve docking component 5 can be adjusted arbitrarily on the extension sleeve 4. Therefore, the valve sleeve 3 fixed by the sleeve docking component 5 can be extended at will, thereby improving the practicability of the wrench 1.

[0030] The transmission mechanism 7 includes a ratchet wheel 701 and a push piece 702. A driving hole is opened at the upper end of one side of the wrench 1, and a groove is opened around the inside of the driving hole. The ratchet wheel 701 is fixedly sleeved outside the extension base 2, the ratchet wheel 701 is located inside the groove, a through hole is opened in the middle of one side inside the groove, the push piece 702 is attached to the upper end outside the ratchet wheel 701, and a spring ejector rod 703 is arranged inside the through hole. One end of the piston rod of the spring ejector rod 703 is fixedly connected to the top of the push piece 702.

[0031] As Figures 1 to 3 shown, through the design that one end of the piston rod of the spring ejector rod 703 is fixedly connected to the top of the push piece 702, the wrench 1 can cooperate with the push piece 702 and the spring ejector rod 703, which can facilitate the staff to rotate the wrench 1 repeatedly and quickly control the valve sleeve 3 after docking to perform the valve closing work.

[0032] The sleeve docking component 5 includes a sliding sleeve housing 504 and multiple groups of lead screws 507. The sliding sleeve housing 504 is slidably sleeved outside the extension sleeve 4. Multiple groups of lead screws 507 are all rotatably connected to the sliding sleeve housing 504, and the lead screws 507 are arranged in an annular and equidistant manner. Transmission plates 502 are connected to the outside of multiple groups of lead screws 507 through threads. Docking clamping blocks 501 are fixedly installed at the same end of multiple groups of transmission plates 502, and multiple groups of docking clamping blocks 501 are all arc-shaped.

[0033] As Figure 4 shown, through the design that multiple groups of docking clamping blocks 501 are all arc-shaped, since most of the valve sleeves 3 on the market are cylindrical, and multiple groups of docking clamping blocks 501 can rely on the arc-shaped side to contact the valve sleeve 3 more, thereby further improving the stability of multiple groups of docking clamping blocks 501 when clamping the valve sleeve 3.

[0034] There is a rotating groove formed around the inner circumference of the sliding sleeve 504. A main bevel gear 505 is rotatably connected inside the rotating groove. A hollow knob 503 is fixedly installed around one side of the main bevel gear 505. A plurality of driven bevel gears 506 are meshed and connected around one side of the main bevel gear 505. A plurality of transmission grooves are formed around one side inside the rotating groove. The plurality of driven bevel gears 506 are respectively rotatably installed inside the plurality of transmission grooves. A plurality of lead screws 507 are respectively fixedly installed at the middle of the side of the plurality of driven bevel gears 506 close to the extension sleeve 4.

[0035] As Figure 4 and Figure 5 shown, through the design that the plurality of driven bevel gears 506 are all meshed and connected with the main bevel gear 505, the main bevel gear 505 can drive the plurality of lead screws 507 to rotate simultaneously, enabling the plurality of docking clamping blocks 501 to approach each other simultaneously, thereby stably clamping the valve sleeve 3 and realizing the docking work between the extension sleeve 4 and the valve sleeve 3.

[0036] The extension assembly 6 includes a screw rod 604. A drive groove is formed at one end of the extension sleeve 4. The screw rod 604 is rotatably installed at one end inside the drive groove, and an adjustment knob 603 is fixedly installed at one end of the screw rod 604. An adjustment nut 602 is threadedly connected to the outside of the screw rod 604. Avoidance holes are symmetrically formed at both ends of the outside of the extension sleeve 4, and the avoidance holes communicate with the inside of the drive groove. The main bevel gear 505 is hollow, and a rotating sleeve 601 is slidably connected around the inner circumference of the main bevel gear 505. The rotating sleeve 601 is fixedly connected to the adjustment nut 602.

[0037] As Figures 4 to 6 shown, through the design that the rotating sleeve 601 is fixedly connected to the adjustment nut 602, the adjustment nut 602 driven by the screw rod 604 can cooperate with the rotating sleeve 601 to control the movement of the valve sleeve 3 that has been fixedly docked by the docking clamping blocks 501. Moreover, the screw rod 604 and the adjustment nut 602 can quickly position the item they drive, thereby facilitating the staff to quickly use the valve sleeve 3 to dock with the gas riser valve;

[0038] It should be noted that when the hollow knob 503 drives the main bevel gear 505 to rotate, the rotating sleeve 601 can avoid rotating along with the main bevel gear 505 due to its own hollow circular characteristic, thereby facilitating the staff to rotate the screw rod 604 to drive the sliding sleeve 504 to move.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
