Description

Technical Field

[0001] This utility model relates to the technical field of water pump accessory positioning, specifically a rotary buckle applied to the installation of water pump accessories. Background Technology

[0002] During operation, water pumps require various accessories to accommodate different pipe diameters, pipe interfaces, and water output requirements. To reliably integrate these accessories into the pump housing when not in use, corresponding mounting positions need to be provided on the housing. Existing methods commonly use rope binding, which, in practice, occupies extra space and hinders safe pump operation. Another method involves pre-setting grooves on the housing to embed the accessories; however, pump vibrations during operation can cause accessories to detach from these grooves. Therefore, there is an urgent need to develop a locking structure suitable for installing water pump accessories, ensuring reliable integration and easy removal when needed. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a rotary buckle for installing water pump accessories, which reliably locks the water pump accessories in place and makes unlocking convenient, allowing the water pump accessories to be easily removed for use.

[0004] A rotary latch for installing water pump accessories, suitable for locking and unlocking water pump accessories, characterized in that it comprises:

[0005] The knob includes a rotating disc and a toggle switch. The center of the lower surface of the rotating disc is provided with a recessed positioning hole. The center of the upper surface of the rotating disc is fixed with a radially outward protruding toggle switch. The lower surface of the rotating disc also includes at least two positioning locking grooves, and the centers of all the positioning locking grooves are arranged in the same circle.

[0006] The accommodating groove includes a circular groove and a toggle-avoiding arc-shaped groove. A short, upward-protruding post is provided at the circular position of the circular groove, and a protrusion is also provided on the upper surface of the circular groove.

[0007] The protruding short post is inserted into the concave positioning hole. The protruding short post serves as the rotating shaft of the knob and the locking mechanism. The knob of the receiving groove avoids a portion of the arc-shaped groove approaching the side of the water pump accessory. The protrusion is embedded in one of the positioning locking grooves. After the concave positioning hole and positioning locking groove of the rotating disc are respectively fastened and pressed onto the corresponding protruding short post and protrusion, the knob position is secured. When the knob is within the surface area of ​​the water pump accessory, the knob is used to lock the water pump accessory. When the knob is not within the surface area of ​​the water pump accessory, the water pump accessory is freely disengaged.

[0008] Its further features are:

[0009] The toggle includes a fixed rotating disc portion and an outwardly protruding portion. The outwardly protruding portion includes a radially inner end portion and a radially outer end portion. The radially inner end portion increases in thickness to reinforce the connection. The bottom of the radially outer end portion is higher than the upper surface of the water pump accessory to be locked.

[0010] The bottom of the radial inner end portion bulges out to the side relative to the thickness region of the rotating disk, and the toggle-avoiding arc groove is a rotation avoidance groove corresponding to the bottom position of the radial inner end portion.

[0011] The fixed rotating disk portion of the knob is provided with several lateral protruding connecting ribs, which make the entire knob easy to operate and make the entire knob firm and reliable.

[0012] The lower surface of the rotating disc includes four positioning and locking grooves, which enable the knob to quickly adapt to the corresponding protrusions in different accommodating grooves for locking and unlocking operations.

[0013] After adopting the above technical solution, one or more receiving grooves are provided on one side of the water pump accessory, and the receiving grooves are provided with an upward protruding short post for installing a rotatable knob and a protrusion for positioning the radial protrusion of the knob. In actual use, when the knob is located within the surface area of ​​the water pump accessory, the knob is used to lock the water pump accessory. When the knob is not within the surface area of ​​the water pump accessory, the water pump accessory is freely disengaged. This makes the water pump accessory reliably locked and easy to unlock, making it easy to take out the water pump accessory for use. Attached Figure Description

Detailed Implementation

[0019] A rotary latch for installing water pump accessories, specifically, is used for locking and unlocking water pump accessories placed in the placement groove 10, see [link to details]. Figures 1-3 It includes: a knob 20 and a receiving groove 30;

[0020] The knob 20 includes a rotating disc 21 and a toggle 22. A recessed positioning hole 211 is provided at the center of the lower surface of the rotating disc 21. A radially protruding toggle 22 is fixed at the center of the upper surface of the rotating disc 21. The lower surface of the rotating disc 21 also includes at least two positioning locking grooves 212, and the centers of all the positioning locking grooves 212 are arranged in the same circle.

[0021] The receiving groove 30 includes a circular groove 31 and a toggle-avoiding arc-shaped groove 32. A short, upward-protruding post 311 is provided at the circular position of the circular groove 31, and a protrusion 312 is also provided on the upper surface of the circular groove 31.

[0022] The protruding short post 311 is inserted into the concave positioning hole 211. The protruding short post 311 is the rotating shaft of the knob 20 and the fixed sleeve locking mechanism. The toggle of the receiving groove 30 avoids a part of the arc-shaped groove 32 and connects to the side of the placement groove 10. The protrusion 312 is embedded in one of the positioning locking grooves 212. After the concave positioning hole 211 and the positioning locking groove 212 of the rotating disc 21 are respectively fastened and pressed onto the corresponding protruding short post 311 and protrusion 312, the knob 20 is fixed in position. When the toggle 22 of the knob 20 is within the surface area of ​​the placement groove 10, the toggle 22 is used to lock the water pump accessories. When the toggle 22 is not within the surface area of ​​the placement groove 10, the water pump accessories are freely disengaged from the placement groove 10.

[0023] In a specific embodiment, the toggle 22 includes a fixed rotating disk portion 221 and an outwardly protruding portion 222. The outwardly protruding portion 222 includes a radially inner end portion 2221 and a radially outer end portion 2222. The radially inner end portion 2221 is thickened in the thickness direction for reinforcing the connection, and the bottom of the radially outer end portion 2222 is higher than the upper surface of the water pump accessory to be locked.

[0024] The bottom of the radial inner end portion 2221 bulges out to the side relative to the thickness area of ​​the rotating disk 21, and the toggle-avoiding arc groove 32 is a rotation avoidance groove corresponding to the bottom position of the radial inner end portion 2221.

[0025] The rotating disc portion 221 of the knob 22 is surrounded by several lateral protruding connecting ribs 2211. The connecting ribs 2211 make the entire knob 20 easy to operate and make the entire knob 20 firm and reliable.

[0026] In a specific embodiment, the lower surface of the rotating disk 21 includes four positioning and locking grooves 212, which enable the knob 20 to quickly adapt to the corresponding protrusions 312 of different receiving grooves 30 for locking and unlocking operations.

[0027] Its working principle is as follows: A receiving groove 30 is set on each side of the placement groove 10 (see Figure 1 and Figure 2 The recess 30 is provided with an upwardly protruding short post 311 for installing the rotatable knob 20 and a protrusion 312 for positioning the radially protruding part of the knob 22. In actual use, when the knob 22 of the knob 20 is located within the surface area of ​​the recess 10, the knob 22 is used to lock the water pump accessories. When the knob 22 is not within the surface area of ​​the recess 10, the water pump accessories are freely disengaged from the recess. This makes the water pump accessories reliably locked in the recess 10 and easy to unlock, making it convenient to take out the water pump accessories for use.
