[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-4 As shown, a pump shaft mounting box assembly includes a pump shaft mounting box housing 1, a shaft alignment unit 3, a limiting insertion groove 14, an insertion top plate 33, a lower support frame 31, a limiting plate 34, and a pump shaft component 2. The pump shaft mounting box housing 1 has a limiting insertion groove 14 on its lower side. The limiting insertion groove 14 is rectangular in design, which makes it less likely for the object to be inserted to rotate or deviate during use. In order to achieve the alignment effect when inserted with the pump shaft mounting box housing 1, part of the shaft alignment unit 3 is inserted into the limiting insertion groove 14. The shaft alignment unit 3 includes an insertion top plate 33 inserted into the limiting insertion groove 14.

[0023] The length of the island-limiting insertion groove 14 of the shaft centering unit 3 is the length of the built-in shaft groove 11 on one side, which prevents the insertion top plate 33 from being unable to fit with the pump shaft mounting box housing 1. The bottom of the insertion top plate 33 is detachably connected to a lower support frame 31, which is used to support the height of the insertion top plate 33. The plane where the lowest point of the lower support frame 31 is located is coplanar with the plane where the lowest point of the pump shaft mounting box housing 1 is located, to prevent the insertion top plate 33 from deviating during use. A limit plate 34 is provided on the insertion top plate 33. The limit plate 34 is located outside the pump shaft mounting box housing 1. The limit plate 34 and the pump shaft mounting box housing 1 are coaxially distributed. The limit plate 34 is as follows: Figure 4The design is arc-shaped, and the arc and the pump shaft mounting housing 1 are coaxially distributed to support the pump shaft 2 and the pump shaft mounting housing 1 for centering installation. When the pump shaft 2 and the built-in shaft groove 11 are inserted, the centering insertion of the pump shaft 2 and the built-in shaft groove 11 is achieved by observing the fit between the pump shaft 2 and the limiting plate 34, which reduces the installation time of the workers and also reduces the probability of deviation between the pump shaft 2 and the pump shaft mounting housing 1 during installation.

[0024] The effect achieved by the entire embodiment is that, during use, the top plate 33 and the limiting insertion slot 14 are inserted. At this time, the lowest point of the lower support frame 31 and the lowest point of the pump shaft mounting housing 1 are in a coplanar state, thereby reducing the probability of the top plate 33 tilting during support. At this time, due to the limiting plate 34 as... Figure 4 The design is arc-shaped, and the arc and the pump shaft mounting housing 1 are coaxially distributed to support the pump shaft 2 and the pump shaft mounting housing 1 for centering installation, reducing the probability of deviation between the pump shaft 2 and the pump shaft mounting housing 1 during installation.

[0025] Example 2

[0026] like Figures 1-4 As shown, a pump shaft mounting box assembly includes an upper support frame 35, a pump shaft component 2, a support plate 15, abutment interface 32, and mounting component 13. The top of the top plate 33 is detachably connected to the upper support frame 35, which supports the limiting plate 34. The length of the upper support frame 35 should be adapted to the distance from the highest point of the limiting insertion groove 14 to the center of the pump shaft mounting box housing 1. The length of the upper support frame 35 is not unique and should be selected according to the currently selected pump body model. The top of the upper support frame 35 is connected to the bottom of the limiting plate 34 to support the limiting plate 34 and realize the centering and fixing of the pump shaft component 2 and the pump shaft mounting box housing 1 with the assistance of the limiting plate 34.

[0027] A portion of the pump shaft component 2 is inserted into the pump shaft mounting housing 1. The bottom end of the pump shaft component 2 abuts against the top end of the limiting plate 34. The pump shaft component 2 is used to connect the pump shaft mounting housing 1. During specific installation, the surface of the pump shaft component 2 also has additional sleeve bearings and sealing structures. Since this solution has not optimized it, and this part is also a publicly available technology in different models, it will not be described in detail.

[0028] To ensure that the pump shaft mounting housing 1 can be horizontally installed on the object, a support plate 15 is detachably connected to the bottom of the pump shaft mounting housing 1 using existing installation techniques such as bolts or clips. The bottom of the support plate 15 is flat and can fit snugly against the object being installed. Of course, if the part where the object being installed and the support plate 15 are connected is not flat, then a matching support plate 15 should be replaced. A limiting insertion groove 14 is formed on the support plate 15, with the opening of the limiting insertion groove 14 facing the side of the limiting plate 34, to ensure that the limiting plate 34 and the pump shaft 2 can provide support.

[0029] An abutment interface 32 is provided between the lower support frame 31 and the plug-in top plate 33. The abutment interface 32 abuts against the limiting plug-in groove 14, such as... Figure 4 As shown, the abutment interface 32 is a notch between the lower support frame 31 and the insertion top plate 33. The length of the abutment interface 32 is the same as the length of the limiting insertion groove 14. The design of the abutment interface 32 is to ensure that the lower support frame 31 can fit against the surface of the support plate 15 after the insertion top plate 33 is inserted, reducing the probability of the lower support frame 31 tilting. At the same time, both the insertion top plate 33 and the limiting insertion groove 14 are rectangular designs, and the four side lengths of the insertion top plate 33 are slightly smaller than the four side lengths of the limiting insertion groove 14. After the insertion top plate 33 and the limiting insertion groove 14 are inserted, it is ensured that there will be no self-rotation.

[0030] The bottom end of the support plate 15 is welded with a connecting mounting part 13. The mounting part 13 has a threaded groove for locking and fixing the pump shaft mounting box housing 1. The bottom surface of the mounting part 13, like the support plate 15, needs to change according to the shape of the connecting surface of the object being installed, so as to connect and fix it with the object being fixed.

[0031] The overall effect of the second embodiment is as follows: First, the length of the upper support frame 35 is adapted to the distance from the highest point of the limiting insertion groove 14 to the center of the pump shaft mounting housing 1, to ensure the support of the upper support frame 35 on the limiting plate 34, thereby achieving the centering and fixing of the limiting plate 34 to the pump shaft component 2 and the pump shaft mounting housing 1. At the same time, the bottom of the support plate 15 is flat, which can fit against the object being installed. Of course, if the part where the object being installed and the support plate 15 are connected is not flat, then a matching support plate 15 should be replaced accordingly. Also, the bottom surface of the mounting component 13, like the support plate 15, needs to change according to the shape of the connecting surface of the object being installed, for connection and fixing with the object being fixed. Finally, as shown in the figure... Figure 4As shown, the abutment interface 32 is a notch between the lower support frame 31 and the insertion top plate 33. The length of the abutment interface 32 is the same as the length of the limiting insertion groove 14. The design of the abutment interface 32 is to ensure that the lower support frame 31 can fit against the surface of the support plate 15 after the insertion top plate 33 is inserted, reducing the probability of the lower support frame 31 tilting. At the same time, both the insertion top plate 33 and the limiting insertion groove 14 are rectangular designs, and the four side lengths of the insertion top plate 33 are slightly smaller than the four side lengths of the limiting insertion groove 14. After the insertion top plate 33 and the limiting insertion groove 14 are inserted, it is ensured that there will be no self-rotation.

[0032] Example 3

[0033] like Figures 1-4 As shown, a pump shaft mounting box assembly includes an internal shaft groove 11, a front cover groove 12 and a rear cover groove. The internal shaft groove 11 is provided inside the pump shaft mounting box housing 1. Both ends of the internal shaft groove 11 extend outside the pump shaft mounting box housing 1 for inserting a pump shaft component 2.

[0034] The pump shaft mounting housing 1 has a front cover groove 12 at one end of the limiting plate 34, and a rear cover groove at the opposite end of the front cover groove 12. The front cover groove 12 is used to install the front cover by bolts, and the rear cover groove is used to install the rear cover by bolts.

[0035] The effect achieved by the entire embodiment three is as follows: first, the front cover is installed at the front cover groove 12 position, and then the pump shaft 2 and the built-in shaft groove 11 are inserted. At this time, the pump shaft 2 will be aligned with the built-in shaft groove 11 under the action of the limiting plate 34. Then, the rear cover is installed at the rear cover groove by bolts to complete the installation of the pump shaft 2 and the pump shaft mounting box housing 1. After installation, the shaft alignment unit 3 can be removed and reused repeatedly. It can be used again for auxiliary alignment when the two pump shaft mounting box housings 1 are docked.

[0036] Working principle: When using this pump shaft mounting box assembly, check whether each component is in good condition. First, install the front cover at the front cover groove 12 position. Then, insert the pump shaft 2 and the internal shaft groove 11. Insert the top plate 33 and the limiting insertion groove 14. At this time, the lowest point of the lower support frame 31 and the lowest point of the pump shaft mounting box housing 1 are coplanar to reduce the probability of the top plate 33 tilting during support. At this time, due to the limiting plate 34 as... Figure 4 The design is arc-shaped, and the arc and the pump shaft mounting box housing 1 are coaxially distributed to support the pump shaft 2 and the pump shaft mounting box housing 1 for centering installation. When the pump shaft 2 and the built-in shaft groove 11 are inserted, the centering insertion of the pump shaft 2 and the built-in shaft groove 11 is achieved by observing the fit between the pump shaft 2 and the limiting plate 34, which reduces the installation time of the workers and also reduces the probability of deviation between the pump shaft 2 and the pump shaft mounting box housing 1 during installation.

[0037] Secondly, when inserting the top plate 33, the length of the upper support frame 35 is adapted to the distance from the highest point of the limiting insertion groove 14 to the center of the pump shaft mounting housing 1. This ensures that the upper support frame 35 supports the limiting plate 34, thereby achieving the centering and fixing of the limiting plate 34 to the auxiliary pump shaft component 2 and the pump shaft mounting housing 1. Simultaneously, the bottom of the support plate 15 is flat, allowing it to fit snugly against the object being installed. Of course, if the connection between the object being installed and the support plate 15 is not flat, a matching support plate 15 should be replaced. The bottom surface of the mounting component 13, like the support plate 15, needs to adapt to the shape of the connection surface of the object being installed for connection and fixing. Finally, as... Figure 4 As shown, the abutment interface 32 is a notch between the lower support frame 31 and the insertion top plate 33. The length of the abutment interface 32 is the same as the length of the limiting insertion groove 14. The design of the abutment interface 32 is to ensure that the lower support frame 31 can fit against the surface of the support plate 15 after the insertion top plate 33 is inserted, reducing the probability of the lower support frame 31 tilting. At the same time, both the insertion top plate 33 and the limiting insertion groove 14 are rectangular designs, and the four side lengths of the insertion top plate 33 are slightly smaller than the four side lengths of the limiting insertion groove 14. After the insertion top plate 33 and the limiting insertion groove 14 are inserted, it is ensured that there will be no self-rotation. Then, the rear end cover is installed at the rear end cover groove with bolts to complete the installation of the pump shaft component 2 and the pump shaft mounting box housing 1. After installation, the shaft alignment unit 3 can be removed and reused repeatedly. It can be used again for auxiliary alignment when the two pump shaft mounting box housings 1 are docked, and finally the pump shaft mounting box assembly is completed.
