Description

Technical Field

[0001] The utility model relates to the technical field of water quality detectors, in particular to a detection sleeve connection structure of a water quality detector. Background Art

[0002] In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge. The decline in drinking water quality is extremely harmful to human health. Water quality detectors play an important role in environmental protection, water quality detection and water resource protection. Water quality detectors are generally installed and connected to the detection head and the detector body by threaded installation. However, the water quality contains a large amount of impurities. After these impurities enter the connection between the detection head and the detector body, it is easy to cause the device to get stuck, making it inconvenient to disassemble and replace the detection head. After long-term use, the detection head is prone to fall off in the water, so it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In view of the deficiencies in the prior art, the utility model provides a detection sleeve connection structure for a water quality detector, which has the function of sealing the connection between the groove and the connecting block through a rubber ring to prevent impurities in the water from entering the threaded interface and causing the threaded joint and the threaded interface to get stuck. At the same time, the protrusion and the slot are used to increase the stability of the threaded joint and the threaded interface after connection, and it is easy to disassemble and replace, thereby solving the above-mentioned technical problems.

[0005] (II) Technical solution

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detection sleeve connection structure of a water quality detector, including a detector device, a connecting end is fixedly installed at the bottom end of the detector device, a threaded interface is provided inside the connecting end, and a connecting end is fixedly connected to the outer peripheral surface, a groove is provided inside the connecting end, a threaded joint is rotatably installed inside the threaded interface, a connecting block is fixedly installed on the outer peripheral surface of the threaded joint, and an anti-slip sleeve is fixedly installed on the bottom end of the outer peripheral surface, a clamping block is fixedly installed on the outer peripheral surface of the threaded joint, a protrusion is arranged inside the clamping block, a clamping groove is provided at the top end of the connecting end, a spring is fixedly installed at the top end of the clamping groove, a pressure block is fixedly installed on the top of the spring, an extrusion rod is fixedly installed on the bottom end of the pressure block, and a detection head is fixedly installed on the bottom end of the threaded joint.

[0007] Preferably, a group of threaded interfaces are provided inside the connection end, and a group of threaded joints are rotatably installed inside the threaded interfaces.

[0008] Through the above technical solution, the threaded joint is first aligned with the threaded interface so that the threaded joint and the threaded interface are threadedly connected, thereby realizing that the threaded joint drives the connecting end of the detection head and the detection instrument device to connect, so that the detection head and the detection instrument device can be installed.

[0009] Preferably, a group of anti-slip sleeves are fixedly mounted on the bottom end of the outer peripheral surface of the threaded joint.

[0010] Through the above technical solution, when the device is in the process of water quality detection, a large amount of water stains will accumulate on its outside. These water stains reduce the friction of the outer surface of the device. The anti-slip sleeve increases the friction when installing and disassembling the threaded joint, making it easier to operate.

[0011] Preferably, a group of grooves are provided inside the connecting end, a group of connecting blocks are fixedly installed on the outer peripheral surface of the threaded joint, and a rubber ring is fixedly installed on the top of the connecting block.

[0012] Through the above technical solution, when the threaded joint and the threaded interface are threadedly connected, the connecting block drives the rubber ring to fit into the groove, and the joint between the groove and the connecting block is sealed by the rubber ring to prevent impurities in the water from entering the threaded interface and causing the threaded joint and the threaded interface to get stuck.

[0013] Preferably, two groups of clamping blocks are fixedly installed on the outer peripheral surface of the threaded joint, and a group of arc-shaped clamping grooves are opened inside the connecting end.

[0014] Through the above technical solution, when the threaded joint and the threaded interface are threadedly connected, the two sets of clamping blocks are driven to engage with the arc-shaped clamping grooves. Through the action of force, the clamping blocks drive the protrusions to be clamped inside the clamping grooves. At this time, the bottom end of the protrusions abuts against the edge of the clamping groove, thereby increasing the stability of the threaded joint and the threaded interface after connection.

[0015] Preferably, two groups of springs are relatively fixedly installed at the top of the inside of the card slot, a group of pressing blocks is fixedly installed at the top of each group of springs, and an extrusion rod is fixedly installed at the bottom of each group of pressing blocks.

[0016] Through the above technical solution, when it is necessary to disassemble the detector device and the detection head, first press the pressure block to make the pressure block drive the spring to compress and drive the extrusion rod downward, and the bottom end of the extrusion rod squeezes the top of the protrusion to make the protrusion disengage from the inside of the slot, driving the block to separate from the slot, and then rotate the threaded joint in the opposite direction to separate the threaded joint from the threaded interface, so as to facilitate the disassembly and replacement of the detector device and the detection head.

[0017] Compared with the prior art, the utility model provides a detection sleeve connection structure of a water quality detector, which has the following beneficial effects:

[0018] 1. The utility model first aligns the threaded joint with the threaded interface so that the threaded joint and the threaded interface are threadedly connected, thereby realizing that the threaded joint drives the detection head to connect with the connecting end of the detector device, so that the detection head and the detector device can be installed. After the threaded joint and the threaded interface are threadedly connected, the connecting block drives the rubber ring to fit with the groove, and the connection between the groove and the connecting block is sealed by the rubber ring to prevent impurities in the water from entering the threaded interface and causing the threaded joint and the threaded interface to be stuck. When the threaded joint and the threaded interface are threadedly connected, the two groups of clamping blocks are driven to fit with the arc-shaped clamping groove. Through the action of force, the clamping block drives the protrusion to be clamped inside the clamping groove. At this time, the bottom end of the protrusion abuts against the edge of the clamping groove, which increases the stability of the threaded joint and the threaded interface after connection.

[0019] 2. When the detector device and the detection head need to be disassembled, the utility model first presses the pressure block, so that the pressure block drives the spring to compress and drive the extrusion rod downward, and the bottom end of the extrusion rod squeezes the top of the protrusion, so that the protrusion is disengaged from the inside of the card slot, driving the card block to separate from the card slot, and then the threaded joint is rotated in the opposite direction to separate the threaded joint from the threaded interface, so as to facilitate the disassembly and replacement of the detector device and the detection head.

[0028] Specifically, a set of threaded interfaces 3 are provided inside the connection end 2, and a set of threaded joints 6 are threadedly installed inside the threaded interfaces 3. The advantage is that the threaded joints 6 are first aligned with the threaded interfaces 3 so that the threaded joints 6 and the threaded interfaces 3 are threadedly connected, thereby realizing that the threaded joints 6 drive the detection head 15 to connect with the connection end 2 of the detector device 1, so that the detection head 15 and the detector device 1 are installed.

[0029] Specifically, a set of anti-skid sleeves 8 are fixedly installed at the bottom end of the outer peripheral surface of the threaded joint 6. The advantage is that when the device is in the process of water quality detection, a large amount of water stains will accumulate on the outside, and these water stains reduce the friction of the outer peripheral surface of the device. The anti-skid sleeves 8 increase the friction when installing and disassembling the threaded joint 6, which is convenient for operation.

[0030] Specifically, a group of grooves 5 are provided inside the connecting end 4, a group of connecting blocks 7 are fixedly installed on the outer peripheral surface of the threaded joint 6, and a rubber ring is fixedly installed on the top of the connecting block 7. The advantage is that when the threaded joint 6 is threadedly connected with the threaded interface 3, the connecting block 7 drives the rubber ring to fit with the groove 5, and the rubber ring is used to seal the connection between the groove 5 and the connecting block 7, so as to prevent impurities in the water from entering the threaded interface 3 and causing the threaded joint 6 and the threaded interface 3 to be stuck.

[0031] Specifically, two groups of clamping blocks 9 are fixedly installed on the outer circumference of the threaded joint 6, and a group of arc-shaped clamping grooves 11 are opened inside the connecting end 4.

At this time, the bottom end of the protrusion 10 is in contact with the edge of the clamping groove 11, which increases the stability of the threaded joint 6 after being connected with the threaded interface 3.

After the threaded joint 6 and the threaded interface 3 are threadedly connected, the two groups of card blocks 9 are driven to fit with the arc-shaped card groove 11. The locking block 9 drives the protrusion 10 to be locked in the slot 11 through the action of force. At this time, the bottom end of the protrusion 10 abuts against the edge of the slot 11, which increases the stability of the threaded joint 6 and the threaded interface 3 after being connected. When it is necessary to disassemble the detector device 1 and the detection head 15, the pressure block 13 is first pressed to make the pressure block 13 drive the spring 12 to compress and drive the extrusion rod 14 downward. The bottom end of the extrusion rod 14 squeezes the top end of the protrusion 10, so that the protrusion 10 is disengaged from the slot 11, driving the locking block 9 to separate from the slot 11, and then rotating the threaded joint 6 in the opposite direction to separate the threaded joint 6 from the threaded interface 3, which is convenient for disassembly and replacement of the detector device 1 and the detection head 15.
