Technical Field
[0001] The present application relates to the technical field of submersible pumps, and particularly to an improved switch wire clamping buckle structure for a submersible pump. Background Art
[0002] A submersible pump is a commonly used drainage and water supply device, which is widely used in the water intake process of water sources such as rivers, lakes, and deep wells; most submersible pumps are controlled within the effective highest water level and lowest water level by a floating ball. The most common floating ball is connected by an electric wire, and a switch is arranged in the floating ball. When the floating ball rises to the highest position with the water level, the switch in the floating ball is turned on, the switch is closed, and the submersible pump starts to work. When the floating ball drops to the lowest permitted position with the water level, the switch in the floating ball is turned off, and the water pump stops working.
[0003] The tail of the floating ball electric wire is bent upward in an arc and then fixed on the handle of the water pump. However, once the electric wire is fixed, it is very difficult to change the height of the floating ball, resulting in the inability to adjust the height of the floating ball later. Eventually, the water intake water level height of the water pump cannot be adjusted, thus limiting the scope of use of the water pump. Due to the above defects, a patent named an improved switch wire clamping buckle for a submersible pump (application number: 2020200786640) is proposed. When the submersible pump needs to intake water at a high water level, the floating ball is placed vertically upward, and then the wire clamping buckle is inserted and fixed into the card slot from top to bottom, so that the floating ball is located at a high position and the water intake water level height of the submersible pump is relatively high. When the submersible pump needs to intake water at a low water level, the floating ball is placed vertically downward, and then the wire clamping buckle is inserted and fixed into the card slot from bottom to top, so that the floating ball is located at a low position and the water intake water level height of the submersible pump is relatively low.
[0004] As can be seen from the above prior art, by changing the installation direction of the wire clamping buckle and the card slot to control the height of the floating ball, but there are only two positions for the installation height of the floating ball, resulting in a single water intake water level height of the submersible pump, which cannot meet the requirements of customers. Summary of the Utility Model
[0005] The purpose of the present utility model is to provide an improved switch wire clamping buckle structure for a submersible pump in view of the defects and deficiencies of the prior art.
[0006] To achieve the above purpose, the present utility model adopts the following technical solutions:
[0007] It includes a pump body, a floating ball, a wire clamping buckle, and a fixing seat. The wire clamping buckle is installed at the tail end of the floating ball, the fixing seat is arranged on the side wall of the pump body, the wire clamping buckle includes a fixing buckle, a rotating groove for the end of the fixing buckle to be rotatably connected is provided in the fixing seat, and a fixing bolt is rotatably threaded in the side wall of the fixing seat. One end of the fixing bolt passes through the side wall of the fixing seat and abuts against the side wall of the fixing buckle.
[0008] Preferably, a plurality of sliding blocks are circumferentially and uniformly arranged on the inner side wall at the opening of the fixed seat. The sliding blocks slide along the radial direction of the fixed seat. A compression spring is arranged between the sliding blocks and the inner circumferential side wall of the fixed seat, and the compression spring drives the sliding blocks to move towards the central axis of the fixed seat.
[0009] Preferably, a first guiding surface is formed on the outer side wall of one end of the sliding block, and a second guiding surface cooperating with the first guiding surface is circumferentially formed on the periphery of one end of the fixing buckle.
[0010] Preferably, a plurality of limiting bolts are circumferentially and uniformly arranged on the outer peripheral side of the fixed seat. One end of the limiting bolt passes through the side wall of the fixed seat and is fixed inside the inner end of the sliding block.
[0011] Preferably, a plurality of clamping blocks are uniformly arranged on the inner circumferential wall of the fixed seat, and a plurality of clamping grooves for clamping and cooperating with the clamping blocks are circumferentially and uniformly formed on the periphery of one end of the fixing buckle.
[0012] Preferably, a pull ring is rotatably connected to the outer end of the limiting bolt.
[0013] Preferably, two inserting rods are uniformly arranged at the inner end of the fixed seat, and inserting slots for inserting and fixing the inserting rods are formed on the side wall of the pump body.
[0014] In summary, the present application includes at least one of the following beneficial technical effects:
[0015] 1. When it is necessary to adjust the height of the floating ball, one end of the fixing buckle of the wire clamping buckle is rotated in the rotating groove in the fixed seat, so that the floating ball rotates. During the rotation process, the height of the floating ball will change due to the change of the rotation angle, making the height change of the floating ball diverse and improving the adaptability of the submersible pump.
[0016] 2. When the fixing buckle is installed in the rotating groove of the fixed seat, one end of the fixing buckle is moved close to the opening of the fixed seat. Then, under the cooperation of the second guiding surface of the fixing buckle and the first guiding surface of the sliding block, the sliding block is moved towards the inside of the fixed seat, thereby compressing the compression spring. Until one end of the fixing buckle is located in the rotating groove, the sliding block rebounds under the action of the compression spring, and one end of the sliding block abuts against the side wall of the fixing buckle. At this time, the side wall of the sliding block and the side wall of the fixing buckle are mutually attached, so that the fixing buckle is clamped in the rotating groove of the fixed seat, improving the convenience of installing the fixing buckle and the fixed seat.
[0017] 3. When one end of the fixing buckle is rotated in the rotating groove of the fixed seat, pre-fixing is carried out under the mutual cooperation of the clamping block and the clamping groove. Then, the fixing bolt is rotated so that the inner end of the fixing bolt abuts against the side wall of the fixing buckle, improving the stability of rotating the fixing buckle.

The card seat 5 is for the tail end of the floating ball 2 to be inserted and fixed. One end of the connecting column 7 is integrally arranged on one side of the card seat 5. One end of the fixed column 8 is integrally arranged at the end of the connecting column 7 far from the card seat 5. The fixed seat 4 includes a mounting seat 9 and a cover plate 10. The vertical cross-section of the mounting seat 9 is in two symmetrical "L" shapes. One end of the cover plate 10 is inserted into the mounting seat 9. There is a rotating groove 11 in the fixed seat 4 for the fixed column 8 to be rotatably connected. A fixing bolt 12 is inserted through the outside of the mounting seat 9. One end of the fixing bolt 12 sequentially passes through the side wall of the mounting seat 9, then is threadedly mated and rotated through the cover plate 10, and finally abuts against the side wall of the fixed column 8.
[0028] Referring to Figure 1 、 Figure 4 and Figure 5 , after loosening the fixing bolt 12, one end of the fixing buckle 6 of the wire clamping buckle 3 rotates in the rotating groove 11 in the fixing seat 4, causing the floating ball 2 to rotate. During the rotation, the height of the floating ball 2 changes due to the change of the rotation angle.
[0029] Referring to Figure 2 and Figure 3 , there is a sliding ring groove 13 between the inner bottom of the mounting seat 9 and the cover plate 10. A plurality of sliding blocks 14 slide circumferentially and evenly in the sliding ring groove 13. The sliding blocks 14 slide in the radial direction of the fixing seat 4.
