Description

Technical Field

[0001] The utility model relates to the technical field of volute fixing, in particular to a volute fixing tool. Background Art

[0002] Volute is the abbreviation of volute water diversion chamber. Its appearance is very similar to a snail shell, so it is usually referred to as volute. In order to ensure uniform water supply to the water guide mechanism, the cross-section of the volute gradually decreases. At the same time, it can form a necessary ring volume in front of the water guide mechanism to reduce the working intensity of the water guide mechanism. Due to the irregular shape of the volute, special tooling is required for fixing.

[0003] When the current fixing tool is in use, it is extremely inconvenient to fix the volute because most of the volutes are in an oblate shape, and the stability of the volute cannot be guaranteed, which easily causes the volute to deviate. Therefore, we propose a volute fixing tool to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a volute fixing tool to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A volute fixing tool comprises a base plate, the upper surface of which is fixedly connected to two vertical plates, each of which is provided with a slot on the upper surface of the vertical plates, an L-shaped plate is inserted into the interior of each slot, the sides of the two L-shaped plates close to each other are commonly fixedly connected to an arc shell, the sides of the two L-shaped plates away from each other are fixedly connected to a connecting plate, the upper surface of each connecting plate is provided with a through groove, the inner wall of each through groove is slidably connected to a through plate, one end of the two through plates is respectively connected to the side of the two vertical plates away from each other, a group of screw holes are provided on the side of the two L-shaped plates away from each other and the side of the two through plates away from each other, and the inner wall of each group of screw holes is commonly threaded with a screw.

[0007] In a further embodiment, threaded holes are formed on the side surfaces of the two L-shaped plates that are away from each other, a threaded rod is threadedly connected to the inner wall of each threaded hole, and an extrusion plate is fixedly connected to the ends of the two threaded rods that are close to each other.

[0008] In a further embodiment, the side surfaces of the two vertical plates close to each other are fixedly connected to the limiting blocks.

[0009] In a further embodiment, an anti-collision pad is fixedly connected to the inner wall of the arc-shaped shell.

[0010] In a further embodiment, a mounting frame is provided on the upper surface of the base plate, and a group of mounting holes is provided on the upper surface of the mounting frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The device cooperates with the vertical plate, slot, L-shaped plate, arc shell, connecting plate, through slot, through plate, screw holes and screws. When the L-shaped plate is inserted into the slot, the through plate will pass through the through slot, and the arc shell will be sleeved on the outside of the top of the volute. The through plate and the L-shaped plate are connected by screws, so that the arc shell can be fixed above the volute, thereby stabilizing the volute and avoiding the volute from deviating from its position.

DETAILED DESCRIPTION

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The two L-shaped plates 5 are fixedly connected to each other on one side, and the two L-shaped plates 5 are fixedly connected to each other on the other side.

[0020] A threaded hole 7 is provided on the side surfaces of the two L-shaped plates 5 which are away from each other. A threaded rod 8 is threadedly connected to the inner wall of each threaded hole 7. An extrusion plate 9 is fixedly connected to the ends of the two threaded rods 8 which are close to each other. A turning handle is installed on the other end of the threaded rod 8. The turning handle facilitates the staff to rotate the threaded rod 8. When the threaded rod 8 is rotated, the extrusion plate 9 will approach the volute, and can gradually form a support for the volute, thereby enhancing the stability of the volute.

[0021] The side surfaces of the two vertical plates 4 that are close to each other are fixedly connected to the limiting blocks 15. The setting of the limiting blocks 15 can be used to limit the position of the volute, so that it is convenient for the staff to install the volute.

[0022] The inner wall of the arc-shaped shell 6 is fixedly connected with an anti-collision pad 17 , and the anti-collision pad 17 can be used to prevent the volute and the inside of the arc-shaped shell 6 from being damaged by friction.

[0023] An installation frame 3 is provided on the upper surface of the base plate 1, and a group of installation holes 2 are provided on the upper surface of the installation frame 3. The cooperation between the installation frame 3 and the installation holes 2 makes it convenient for the staff to connect the bottom of the volute with the installation frame 3, thereby forming a preliminary stability for the volute, which is convenient for the staff to reinforce the volute later.

[0024] The working principle of the utility model is: when in use, the bottom of the volute is first fixed on the mounting frame 3, and then the two L-shaped plates 5 are respectively inserted into the slots 16, the arc shell 6 will be sleeved on the outside of the top of the volute, and at the same time the through plate 14 will pass through the through slot 13, the screw hole 11 on the through plate 14 will be aligned with the screw hole 11 on the L-shaped plate 5, and then the through plate 14 and the L-shaped plate 5 are connected by screws 10, so that the arc shell 6 can be stabilized on the volute, so that the volute can maintain a stable shape and avoid the volute from deviating from its position.
