Description

Technical Field

[0001] This utility model relates to the field of metering pump technology, specifically to an installation mechanism for metering pumps. Background Technology

[0002] A metering pump is a reciprocating positive displacement pump that can accurately measure and regulate the flow rate of fluids. It can precisely deliver various liquids according to a set flow rate and direction, and is widely used in applications requiring precise control of chemical dosage or liquid ratio.

[0003] When installing and fixing the metering pump body, multiple sets of locking bolts are required. However, the metering pump body will vibrate during long-term use, which may cause the metering pump body to move. Moreover, if water is supplied through a connecting hose, the vibration may cause the connecting hose to bend, affecting the water intake efficiency. Therefore, we propose an installation mechanism for the metering pump. Utility Model Content

[0014] 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.

[0015] Please see Figures 1-4 This utility model provides a technical solution: an installation mechanism for a metering pump, including a preliminary positioning mechanism 1 and a metering pump body 3. The preliminary positioning mechanism 1 has multiple sets of installation slots 2. A feed pipe 5 and a discharge pipe 4 for feeding and discharging are provided on one side of the preliminary positioning mechanism 1. The metering pump body 3 is initially placed and snapped into the interior of the preliminary positioning mechanism 1. The preliminary positioning mechanism 1 and the metering pump body 3 are reinforced by a secondary reinforcement mechanism 6. A position guide mechanism 7 to prevent the connecting hose from being pulled and bent is provided on the outside of the feed pipe 5.

[0016] The initial positioning mechanism 1 and the mounting slot 2 can be fixedly installed using locking screws. The initial positioning mechanism 1 can initially position the metering pump body 3 to prevent it from wobbling left and right during use. Then, the secondary reinforcement mechanism 6 can be used for secondary reinforcement to ensure the fixed installation of the metering pump body 3. The position guide mechanism 7 can prevent the connecting hose from bending due to vibration of the metering pump body 3 when connecting the connecting hose to the feed pipe 5, thus ensuring stable feeding.

[0017] Please see Figures 1-3 The initial positioning mechanism 1 includes a mounting plate 8, a connecting frame 9, positioning claws 10, and positioning blocks 11. The metering pump body 3 is fixedly mounted on the connecting frame 9. Positioning claws 10 are fixedly connected to the four corners of the bottom of the connecting frame 9. Positioning blocks 11 inserted into the positioning claws 10 are fixedly connected to the top of the mounting plate 8.

[0018] When the metering pump body 3 needs to be initially positioned, the connecting bracket 9 and positioning claw 10 at the bottom of the metering pump body 3 are inserted into the outside of the positioning block 11. At this time, the outer wall of the positioning block 11 contacts the inner wall of the positioning claw 10, which can prevent the metering pump body 3 from shaking back and forth or left and right during use.

[0019] Please see Figures 1-3 The secondary reinforcement mechanism 6 includes a locking plate 12, a reinforcement plate 13, and a locking bolt 14. Two sets of locking plates 12 are fixedly connected to the top of the connecting frame 9, and a reinforcement plate 13 is fixedly connected to the top of the mounting plate 8. The locking plate 12 and the reinforcement plate 13 are threadedly connected by the locking bolt 14.

[0020] After the metering pump body 3 is initially positioned, the locking plate 12 and the reinforcing plate 13 will fit together. Then, the locking bolts 14 can be used to fix the locking plate 12 and the reinforcing plate 13, thereby completing the secondary reinforcement and locking of the metering pump body 3.

[0021] Please see Figure 1 and Figure 4The position guiding mechanism 7 includes an external threaded tube 15, an adjusting threaded sleeve 16, a protective frame 17, and a guide frame 18. The bottom of the feed tube 5 is fixedly connected to the external threaded tube 15. The external thread of the external threaded tube 15 is connected to the adjusting threaded sleeve 16. The external thread of the adjusting threaded sleeve 16 is fixedly connected to the outside of the adjusting threaded sleeve 16. The bottom of the protective frame 17 is set as an arc-shaped guide frame 18.

[0022] The external connecting hose is connected to the feed pipe 5 by a nut. Then, the threaded sleeve 16 is rotated and adjusted to descend along the external threaded pipe 15. This allows the protective frame 17 and the guide frame 18 to descend. The arc-shaped guide frame 18 is used to position the connecting hose and prevent the external connecting hose from bending.

[0023] Please see Figure 2 and Figure 3 The outer wall of the locking plate 12 and the inner wall of the reinforcing plate 13 are both set to be mutually fitted arc shapes. The arc shape of the locking plate 12 and the reinforcing plate 13 can be used to position the locking plate 12 and the reinforcing plate 13 and can prevent the locking plate 12 and the reinforcing plate 13 from moving left and right.

[0024] Please see Figure 3 The top of the reinforcing plate 13 is provided with an inclined chamfer 19, which prevents the reinforcing plate 13 from blocking the connection bracket 9 and the positioning claw 10 when they are inserted.

[0025] In use, firstly, the initial positioning mechanism 1 and the mounting slot 2 can be fixed in place using locking screws. Then, the initial positioning mechanism 1 provides initial positioning of the metering pump body 3, preventing it from wobbling during use. Subsequently, the secondary reinforcement mechanism 6 provides secondary reinforcement to ensure the metering pump body 3 is securely installed. The position guide mechanism 7 prevents the connecting hose from bending due to vibration when connecting the metering pump body 3 to the feed pipe 5, ensuring stable feeding. When initial positioning of the metering pump body 3 is required, the connecting bracket 9 and positioning claw 10 at the bottom of the metering pump body 3 are inserted into the outside of the positioning block 11. The outer wall of the positioning block 11 contacts the inner wall of the positioning claw 10, thereby preventing the metering pump body 3 from shaking back and forth or left and right during use. After the metering pump body 3 is initially positioned, the locking plate 12 and the reinforcing plate 13 will fit together. Then, the locking bolt 14 can be used to fix the locking plate 12 and the reinforcing plate 13, thereby completing the secondary reinforcement and locking of the metering pump body 3. The external connecting hose is connected to the feed pipe 5 using a nut. Then, the threaded sleeve 16 is rotated and adjusted to descend along the external threaded pipe 15, so that the protective frame 17 and the guide frame 18 can descend. In this way, the connecting hose can be positioned using the arc-shaped guide frame 18 to prevent the external connecting hose from bending.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
