[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-3, the utility model provides a technical solution for an auxiliary positioning mechanism for valve installation: including a bottom plate 1 and a valve body 2. At the middle position of the outer top of the bottom plate 1, a support sleeve 3 is fixedly installed. An inner fixing plate 4 is sleeved inside the support sleeve 3, and a lifting component for driving the fixing plate 4 to move up and down reciprocally is arranged inside the support sleeve 3. The lifting component includes an open end 10 penetrating through the outer side wall of the fixing plate 4. On the inner side wall of one side of the open end 10, a rack 11 is fixedly installed. A driving shaft rod 12 is rotatably connected to the inner side wall of the support sleeve 3, and a gear 13 is fixedly installed on the outer peripheral surface of the driving shaft rod 12. The gear 13 and the rack 11 are meshed. At the same time, one end of the driving shaft rod 12 passes through the open end 10 and extends to the outer side wall of the support sleeve 3. A first knob 14 is fixedly installed on the outer side wall of the support sleeve 3 and located on the outer peripheral surface of the driving shaft rod 12. When adjusting the height, turn the first knob 14 to drive the driving shaft rod 12 to drive the gear 13 to rotate. Under the meshing characteristic of the gear 13, drive the rack 11 to move up and down, and then make the fixing plate 4 move up and down reciprocally inside the support sleeve 3, so as to adjust the height of the valve body 2 and enable it to be connected to pipes at different heights.

[0022] At the top of the outer side walls on both sides of the fixing plate 4 and above the support sleeve 3, a U-shaped block 5 is rotatably connected through a connecting rod. A square block 6 is fixedly installed on the outer top of the U-shaped block 5, and the outer top of the square block 6 abuts against the outer bottom of the valve body 2. At the same time, horizontal plates 7 are fixedly connected to the bottom of the outer side walls on both sides of the square block 6. Through holes 15 arranged in an annular and equally spaced manner are formed in the bottom of the outer side wall of the U-shaped block 5 and the top of the outer side wall of the fixing plate 4. A plug rod 16 is arranged on the outer side wall of the U-shaped block 5 corresponding to the through holes 15, and the plug rod 16 fixes the fixing plate 4 and the U-shaped block 5 to each other along the inside of the through holes 15. When adjusting the angle, first take out the plug rod 16 from the through hole 15, then push the U-shaped block 5 on the fixing plate 4 to make it rotate at an angle, and then insert the plug rod 16 back into the through hole 15, thereby fixing the U-shaped block 5 and the fixing plate 4 to each other, so as to facilitate the connection of the valve body 2 to pipes at different angles.

[0023] On the outer tops of two transverse plates 7, a first connecting plate 8 and a second connecting plate 9 are respectively slidably connected through a driving assembly. The driving assembly includes first sliding grooves 17 opened on the outer tops of two groups of transverse plates 7. On the inner side walls of two groups of first sliding grooves 17 and inside the square block 6, a bidirectional threaded rod 18 is rotatably connected. One end of the bidirectional threaded rod 18 penetrates through one group of first sliding grooves 17 and is fixedly connected to the output end of a driving motor 19 fixedly installed on the outer side wall of one group of transverse plates 7. On the outer peripheral surface of the bidirectional threaded rod 18 and inside two groups of first sliding grooves 17, sliding blocks are threadedly sleeved. And the outer tops of two groups of sliding blocks are respectively fixedly connected to the outer bottoms of the first connecting plate 8 and the second connecting plate 9. By starting the driving motor 19, the bidirectional threaded rod 18 is driven to drive the sliding blocks to move inside the first sliding grooves 17, and then the first connecting plate 8 and the second connecting plate 9 are respectively driven to perform reciprocating motions of approaching or separating from each other in the first sliding grooves 17, so as to facilitate subsequent fixed clamping of valve bodies 2 of different sizes.

[0024] At both ends of the outer tops of the first connecting plate 8 and the second connecting plate 9, the valve body 2 is clamped and fixed through a limiting assembly. The limiting assembly includes second sliding grooves 20 respectively opened on the outer tops of the first connecting plate 8 and the second connecting plate 9. On the inner side walls of two groups of second sliding grooves 20, bidirectional lead screws 21 are rotatably connected. One end of each of the two bidirectional lead screws 21 penetrates through the second sliding grooves 20 and extends to the outer side walls of the first connecting plate 8 and the second connecting plate 9 respectively. And on the outer peripheral surfaces of the two bidirectional lead screws 21, second knobs 22 are fixedly installed. Inside two groups of second sliding grooves 20 and at both ends of the outer peripheral surfaces of the two bidirectional lead screws 21, first clamping plates 23 and second clamping plates 24 are respectively threadedly sleeved. And on the corresponding inner side walls of two groups of first clamping plates 23 and second clamping plates 24, arc-shaped grooves are opened. By turning the second knobs 22, the two groups of bidirectional lead screws 21 are rotated, and then the first clamping plates 23 and the second clamping plates 24 are respectively driven to limit and fit the two ends of the outer side wall of the valve body 2, which can reduce the problem that the installation is not accurate enough due to shaking during the installation process, resulting in the inability of normal operation between the valve and the pipeline.

[0025] The working principle of the present utility model is as follows: When in use, first place the valve body 2 on the square block 6, then start the driving motor 19 according to the size of the valve body 2, drive the bidirectional threaded rod 18 to drive the sliding blocks to move inside the first sliding grooves 17, and then drive the first connecting plate 8 and the second connecting plate 9 to perform reciprocating motions of approaching or separating from each other in the first sliding grooves 17. After that, turn the second knobs 22 to rotate the two groups of bidirectional lead screws 21, and then drive the first clamping plates 23 and the second clamping plates 24 to limit and fit the two ends of the outer side wall of the valve body 2, thereby fixedly clamping the valve body 2.

[0026] Meanwhile, turn the first knob 14 according to the height of the pipeline to be connected as needed, so that the drive shaft rod 12 drives the gear 13 to rotate. Under the meshing characteristics of the gear 13, the rack 11 is driven to move up and down, and then the fixing plate 4 reciprocates up and down inside the support sleeve 3, so as to drive the valve body 2 to move up and down, thereby achieving the purpose of stably connecting with the corresponding pipeline.

[0027] Meanwhile, take out the insertion rod 16 from the fixing hole 15, then push the U-shaped block 5 to rotate at an angle on the fixing plate 4, and then insert the insertion rod 16 back into the fixing hole 15, thereby fixing the U-shaped block 5 and the fixing plate 4 to each other, so that the valve body 2 is stably connected to pipelines at different angles.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
