Floating ball bracket improved assembly structure

The present invention relates to a float ball bracket improved assembly structure, in particular to a float bracket design suitable for products such as a submersible pump, which can simplify the structure of such a bracket and greatly reduce the manufacturing cost of the overall bracket.

Generally, the submersible pump is installed inside the water tank to extract the liquid, but in order to use the safety, a float switch is usually added to control the automatic operation or stop of the submerged pump to prevent the submerged pump from idling due to no water. burn.

1 shows one of the conventional submersible pump structures provided with such a float switch device. A float ball 11 is provided outside the pump body 10, and the float ball 11 is connected to the pump body 10 by a flexible connector 12. The floating ball 11 is automatically operated when it floats up with the liquid level inside the water tank, but when the liquid level is too low and the float ball 11 is lowered to a low point, the sink pump can be stopped to prevent the damaged condition from occurring. . In order to control the lifting height of the float ball 11, a bracket 13 is generally disposed outside the pump body 10, and then the soft connector 12 of the float ball 11 is clamped and positioned on the bracket 13 via a clamping device 20, via the clamping device. The 20 grips are set at different lengths of the flexible joint 12 to control the float and settling height of the float 11.

As shown in Figures 1A and 1B, the conventional clamping device 20 is basically constituted by two pairs of half-shells 21, 22, wherein the pair of half-shells 21 are provided with an arc-shaped clamping groove 23 and the other half-shell The body 22 is provided with another opposite arcuate clamping groove 24 and a consistent perforation 25 at opposite positions; 23 and the opposite curved clamping groove 24 can clamp the soft connecting tube 12 with respect to the same, and the bracket 13 is inserted into the through hole 25, and then the entire clamping device 20 is locked through the predetermined through hole 26.

The assembly structure of the conventional floating ball described above must use the more complicated clamping device 20, and the overall manufacturing cost is relatively high, except that the through hole 25 must be completely matched to the diameter of the bracket 13.

The purpose of the present invention is to provide a improved assembly structure of the float ball bracket, which can effectively simplify the assembly structure between the float ball joint and the bracket, thereby greatly reducing the production cost and making the whole assembly structure have a better elastic application range.

In order to achieve the above object, the present invention comprises a set of joint structures comprising at least a plurality of identical constituent units, each of the constituent units having a first surface and another opposite second surface, the first surface An oblique arc groove is formed, which is set to a specific concave depth, and the oblique arc groove extends from a corner position of the constituent unit to another corner; the second surface is provided with another and the oblique arc concave The groove is of the same cross-inclined arc groove of the same concave cross-sectional shape, and the intersecting oblique arc groove extends from the other opposite corner position of the position of the constituent unit to the first surface to the other opposite corner; a plurality of through holes are disposed between the oblique arc groove and the intersecting oblique arc groove; the two structural units are reversely connected in parallel, such that the first unit and the other adjacent one of the constituent units are first The surface oblique arc grooves jointly form a clamping groove, and the forming unit and the second surface of the other adjacent constituent unit intersect the oblique arc groove to form another clamping groove for the locking device to pass through the through hole Clamping positioning; can be used A cell group constituting such a structure, the ground to take over the submerged float and pump bracket.

Wherein the first surface oblique arc groove of the constituent unit of the two opposite two-phase reversely connected The commonly formed clamping groove is elastically clamped to the floating ball joint, and the other surface of the second surface intersecting the oblique arc groove is elastically clamped to the bracket.

Wherein, the constituent unit is any one of a rectangular shape, a square shape, and a circular shape, wherein the oblique arc groove and the intersecting oblique arc groove are respectively disposed at a diagonal position of the first surface of the geometric shape, and Another set of diagonal positions of the second surface.

In a possible embodiment, the locking device can be formed only by a bolt inserted through the through hole and a nut locked to the other end of the bolt.

In a preferred embodiment, the two opposite ends are connected in parallel to form a preset spacer on the outer surface of the unit to be tightly coupled by the locking device.

The novelty and other features of the present invention will be apparent from the following detailed description of the embodiments of the drawings.

As shown in FIG. 2, a float ball 11 is also disposed outside the pump body 10, the float ball 11 is connected to the pump body 10 by a flexible connector 12, and a bracket 13 is disposed outside the pump body 10. For example, the sink pump structure is provided with a set of joint structures 30 between the flexible joint 12 of the float ball 11 and the bracket 13.

Referring to Figures 2, 3 and 3A, the assembly structure 30 includes at least a plurality of identical constituent units 31, and the constituent unit 31 is preferably formed of a material such as Nitrile Butadiene Rubber (NBR). Each of the constituent units 31 is formed in a block shape of a specific thickness, and may have a geometric shape such as a rectangle, a square or a circle, and has a first surface 32 and another opposite second surface 33.
