Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning pipe clamps, and in particular to a metal pipe clamp used for fixing an air-conditioning temperature sensor. Background Art

[0002] In air-conditioning units, the common way to install temperature sensors is to set a fixing seat on the pipe clamp, fix the temperature sensor in the fixing seat, squeeze the pipe clamp and the heat exchange tube at the end of the heat exchanger, so that the pipe clamp is compressed and expanded from the clamp mouth, and the heat exchange tube enters the pipe clamp and fits with the temperature sensor for temperature detection; however, when repairing the heat exchanger, the pipe clamp needs to be repeatedly disassembled and assembled, and the clamp mouth and edge of the pipe clamp frequently rub against the heat exchange tube, which is easy to leave scratches on the heat exchange tube, causing wear of the pipe clamp and damage to the heat exchange tube. Therefore, designing a metal pipe clamp for fixing air-conditioning temperature sensors that can reduce wear caused by disassembly and assembly during maintenance has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a metal pipe clamp for fixing an air conditioner temperature sensor.

[0004] The technical solution of the utility model is a metal pipe clamp for fixing an air-conditioning temperature sensor, comprising a retention pipe clamp clamped on the outside of an air-conditioning heat exchange tube and a mounting tube with a temperature sensor connected inside, a docking port is provided on the side of the retention pipe clamp, a detection port for the temperature sensor to extend out is provided on the side of the mounting tube, abutment plates are provided on both sides of the docking port, the length of the abutment plates matches the diameter of the mounting tube, an elastic pressure plate is connected to the outside of the abutment plate, the elastic pressure plate is connected to a positioning buckle fitted with the abutment plate, and both sides of the detection port are connected by metal soft belts, the position of the metal soft belts corresponds to the positioning buckle rings.

[0005] After adopting the above structure, the retention tube clamp is kept on the outer side of the air-conditioning heat exchange tube, and the positioning buckle ring is lifted to bend the elastic pressure plate, so that a gap is formed between the positioning buckle ring and the abutment plate, and the metal soft belt passes through the positioning buckle ring accordingly, so that the pull detection port is aligned with the docking port, and the temperature sensor extending from the detection port is attached to the air-conditioning heat exchange tube for temperature detection; by loosening the positioning buckle ring, the elastic pressure plate is restored to drive the positioning buckle ring to fit the abutment plate, and the metal soft belt is pressed on the abutment plate to fix it, so as to avoid the installation tube and the retention tube clamp from separating; by matching the length of the abutment plate with the diameter of the installation tube, it can be abutted against the outer peripheral surface of the installation tube to block it, so as to avoid the temperature sensor from accumulating dust from the side and affecting the detection accuracy; the positioning buckle ring on the abutment plate is lifted, and the metal soft belt can be connected or removed on the retention tube clamp, and the installation tube can be removed to inspect the temperature sensor therein without removing the retention tube clamp, thereby reducing the damage to the air-conditioning heat exchange tube caused by the disassembly and assembly of the retention tube clamp.

[0006] As a further improvement of the utility model, the metal soft belt is provided with a plurality of stop joints, and the stop joints are arranged at intervals along the length direction of the metal soft belt, and the interval size of the stop joints matches the positioning buckle.

[0007] After adopting the above structure, the metal soft belt is pressed by the positioning buckle, and at the same time it is stuck in the interval of the stop joint and abuts against the stop joint. When the elastic pressure plate is not bent to lift the positioning buckle, the metal soft belt is prevented from being pulled out of the positioning buckle.

[0008] As a further improvement of the utility model, the stop joint is a semi-cylindrical structure, and the rectangular surface of the stop joint is connected to the metal soft belt.

[0009] After adopting the above structure, the stop joint is a semi-cylindrical structure, and the positioning buckle ring contacts the circular surface when pressed down, guiding the positioning buckle ring to slide into the gap of the stop joint for fixation.

[0010] As a further improvement of the present invention, the positioning buckle is connected to a release lever, and the release lever extends over the edge of the abutment plate toward the end surface of the abutment plate.

[0011] After adopting the above structure, a release lever is connected through the positioning buckle, and the release lever extends over the edge of the abutment plate toward the end face of the abutment plate. The release lever is pressed against the edge of the abutment plate, and one end of the release lever extending toward the end face of the abutment plate is pressed down, so that the other end drives the positioning buckle to lift up, forming a space for the metal soft belt to pass through.

[0012] As a further improvement of the utility model, the end surface of the abutment plate is provided with a convex arc surface, and the arc surface corresponds to the outer peripheral surface of the mounting tube.

[0013] With the above structure, the contact plate is provided with an arc surface corresponding to the outer peripheral surface of the mounting tube, thereby reducing the contact area between the contact plate and the mounting tube and reducing the wear of the contact plate when the mounting tube is fixed.

[0018] By keeping the retention tube clamp 1 clamped on the outer side of the air-conditioning heat exchange tube, the positioning buckle ring 7 is lifted to bend the elastic pressure plate 6, and a gap is formed between the positioning buckle ring 7 and the abutment plate 5, and the metal soft belt 8 passes through the positioning buckle ring 7 accordingly, and the pull detection port 4 is aligned with the docking port 3, and the temperature sensor extending from the detection port 4 is attached to the air-conditioning heat exchange tube for temperature detection; by loosening the positioning buckle ring 7, the elastic pressure plate 6 is restored to drive the positioning buckle ring 7 to fit the abutment plate 5, and the metal soft belt 8 is pressed on the abutment plate 5 to fix it, so as to prevent the installation tube 2 from being separated from the retention tube clamp 1; by matching the length of the abutment plate 5 with the diameter of the installation tube 2, it can be abutted against the outer peripheral surface of the installation tube 2 to block it, so as to prevent the temperature sensor from accumulating dust from the side and affecting the detection accuracy; by lifting the positioning buckle ring 7 on the abutment plate 5, the metal soft belt 8 can be connected or removed on the retention tube clamp 1, and the installation tube 2 can be removed to inspect the temperature sensor therein without removing the retention tube clamp 1, thereby reducing the damage caused by the disassembly and assembly of the retention tube clamp 1 to the air-conditioning heat exchange tube.

[0019] The metal soft belt 8 is provided with a plurality of stop joints 9 , which are arranged at intervals along the length direction of the metal soft belt 8 , and the interval size of the stop joints 9 matches the positioning buckle 7 .

[0021] The stop joint 9 is a semi-cylindrical structure, and a rectangular surface of the stop joint 9 is connected to the metal soft belt 8 .

[0022] Because the stopper 9 is a semi-cylindrical structure, the positioning buckle ring 7 contacts the circular surface when pressed down, and guides the positioning buckle ring 7 to slide into the gap of the stopper 9 for fixation.
