Abstract
Description
Technical Field
[0001] This utility model relates to the field of pump body technology, specifically a pump casing that is easy to position and assemble. Background Technology
[0002] The pump casing is the core component of the pump. Its main functions are to provide structural support for the pump, house the impeller, and form a fluid channel to ensure efficient medium transportation. It maintains internal pressure through a sealing design to prevent leakage, while also withstanding fluid impact and vibration to ensure stable pump operation. Existing assembly methods mainly include segmented, horizontal split, and vertical split types. Segmented pump casings connect each stage of the casing with bolts.
[0003] The existing technology, CN219366394U, proposes a pump casing that facilitates positioning and assembly. It includes a base plate, with a first pump casing body and a second pump casing body disposed on the upper side of the base plate. Mounting holes are respectively opened on the adjacent sides of the first and second pump casing bodies. A positioning mechanism is provided on the side of the base plate closest to the first and second pump casing bodies. During installation, after the first and second pump casing bodies are precisely aligned by the positioning mechanism, the operator needs to insert bolts into the mounting holes of both bodies sequentially and tighten them. However, due to the lack of a clear torque feedback mechanism, the operator cannot intuitively perceive the tightness of the bolts. This uncertainty may lead to insufficient or excessive tightening of the bolts. If insufficiently tightened, vibration during equipment operation may cause the bolts to loosen, affecting sealing performance or even causing leakage. If excessively tightened, it may cause thread stripping, local stress concentration in the pump casing, or crushing and deformation of the sealing gasket, thereby reducing assembly quality and shortening component life. Therefore, we have made improvements to this by proposing a pump casing that facilitates positioning and assembly. Utility Model Content
[0004] The purpose of this utility model is to address the problem that operators cannot intuitively perceive the tightness of bolts.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0006] A pump casing that facilitates positioning and assembly, to improve the above-mentioned problems.
[0007] The application is as follows:
[0008] A pump casing for easy positioning and assembly includes a first casing and a second casing, and further includes: a first mounting plate mounted on the first casing; a second mounting plate mounted on the second casing, both the first and second mounting plates having a plurality of mounting holes; and an indicator assembly mounted on the second mounting plate for indicating the tightness of bolts, the indicator assembly including: a contact plate slidably mounted on the second mounting plate; an indicator block rotatably mounted on the second mounting plate; a circular sleeve for driving the indicator block to rotate, the circular sleeve being fixedly mounted to the indicator block; and a circular rod for driving the circular sleeve to rotate, the circular rod being fixedly mounted on the contact plate.
[0009] As a preferred technical solution of this application, it further includes: a groove formed on the annular sleeve, the groove being V-shaped and extending along the axial direction of the annular sleeve; and a protrusion fixedly installed on the round rod, the protrusion sliding within the groove.
[0010] As a preferred technical solution of this application, it further includes: a plurality of springs installed between the contact plate and the mounting plate 2; and a rubber block installed on the contact plate near one end of the mounting plate 1.
[0011] As a preferred technical solution of this application, the number of indicator components is several, and the number of indicator components is the same as the number of mounting holes.
[0012] As a preferred technical solution of this application, it further includes: a plurality of plug rods fixedly installed on the second mounting plate; and a plurality of slot plates fixedly installed on the first mounting plate, wherein the grooves of the slot plates are radially arranged.
[0013] As a preferred technical solution of this application, it further includes: a magnetic block one installed at the end of the insertion rod; and a magnetic block two slidably installed in the slot plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the indicator block points to the preset mark, intuitively displaying the bolt tightness, ensuring that the bolt tightness is just right, and avoiding connection failure or structural damage caused by being too tight or too loose.
[0015] In the scheme of this application:
[0016] By setting multiple indicator blocks, the bolt tightness of different mounting holes can be independently detected simultaneously, ensuring that all bolts reach the standard tightness, improving the consistency and reliability of assembly. In conjunction with the magnetic attraction between the insert rod and the slot plate and between magnetic block one and magnetic block two, mounting plate one and mounting plate two can be quickly aligned and initially fixed, improving assembly efficiency and reducing manual adjustment time.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0028] Example: A pump casing for easy positioning and assembly includes a housing 1 and a housing 2, and further includes: a mounting plate 3 mounted on the housing 1; a mounting plate 5 mounted on the housing 2, wherein both the mounting plate 3 and the mounting plate 5 have a plurality of mounting holes 4; an indicator assembly mounted on the mounting plate 5 for indicating the tightness of bolts, the indicator assembly including: a contact plate 6 slidably mounted on the mounting plate 5; an indicator block 14 rotatably mounted on the mounting plate 5; a circular sleeve 15 for driving the indicator block 14 to rotate, the circular sleeve 15 being fixedly mounted to the indicator block 14; and a circular rod 16 for driving the circular sleeve 15 to rotate, the circular rod 16 being fixedly mounted on the contact plate 6.
[0029] It also includes: a groove 17 formed on the annular sleeve 15, the groove 17 being V-shaped and extending along the axial direction of the annular sleeve 15; and a protrusion 18 fixedly mounted on the round rod 16, the protrusion 18 sliding within the groove 17.
[0030] It also includes: several springs 122 installed between the contact plate 6 and the mounting plate 3; and a rubber block 11 installed on the contact plate 6 near the end of the mounting plate 3.
[0031] The indicator components are of several kinds, and the number of indicator components is the same as the number of mounting holes 4.
[0032] It also includes: a plurality of insert rods 8 fixedly installed on the second mounting plate 5; and a plurality of slot plates 7 fixedly installed on the first mounting plate 3, wherein the grooves of the slot plates 7 are radially arranged.
[0033] It also includes: a magnetic block 9 installed at the end of the insertion rod 8; and a magnetic block 13 slidably installed in the slot plate 7.
[0034] Working principle: During installation, the insert rod 8 is inserted into the slot plate 7. Under the constraint of the shape of the slot plate 7 and the combined effect of the magnetic attraction of the first magnetic block 9 and the second magnetic block 13, the first mounting plate 3 and the second mounting plate 5 can be quickly aligned and initially connected, improving assembly efficiency and reducing manual adjustment time. Then, the bolt is installed at the mounting hole 4. As the bolt is installed, it pushes the contact plate 6 and the round rod 16 to move closer to the annular sleeve 1515. The movement of the contact plate 6 compresses the spring 122. The movement of the round rod 16 drives the annular sleeve 1515 to rotate through the protrusion 18. The rotation of the annular sleeve 1515 drives the indicator block 14 to rotate (marks are set on the mounting plate, and the indicator block 14...). When the indicator point is to the mark, it means that the bolt is tightened. Since the slide 17 is V-shaped, if the bolt is over-tightened, the indicator block 14 will rotate back, thus ensuring that the bolt is tightened to the right degree. In addition, the ring sleeve 1515 is provided with several indicator blocks 14, which can independently detect the tightening status of the bolts at each mounting hole 4. When all indicator blocks 14 point to the corresponding mark, the entire installation process is completed. After installation, the contact block and rubber block 11 are pressed tightly against the mounting plate 2 5 under the action of the spring force of the spring 122, so as to achieve the sealing of the housing 1 and housing 2 after installation, prevent liquid, gas or dust from seeping in, and improve the protective performance of the overall structure.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
