Description

Technical Field

[0001] This utility model belongs to the field of fire sprinkler technology, and in particular relates to a connector for a fire sprinkler. Background Technology

[0002] Fire sprinkler connectors are components used to connect fire sprinklers to fire duct systems. They need to have good pressure resistance and sealing performance to ensure that the fire protection system can work promptly and effectively in the event of a fire.

[0003] In the prior art, threaded connectors are usually used to connect sprinkler heads to water pipes. Although this method is convenient to install and relatively easy to disassemble, and easy to maintain and replace, its connection strength is low and it is easily affected by installation quality, material fatigue and long-term use, which can lead to loosening of threads, leakage or even breakage, thereby affecting the normal operation and safety of the fire protection system. Therefore, we propose a connector for fire sprinkler heads. Utility Model Content

[0004] The purpose of this utility model is to provide a connector for a fire sprinkler head. Through the design of components such as the control shaft, moving plate and locking sleeve of the connecting mechanism, the problems of unstable connection and poor sealing performance in the prior art are solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a connector for a fire sprinkler head, including a connector body, a locking sleeve 1 sleeved on the circumferential surface of the connector body, a fixing plate fixedly connected to the top of the locking sleeve 1, and a connecting mechanism provided on the circumferential surface of the locking sleeve 1.

[0007] The connecting mechanism includes a control shaft that passes through and is rotatably connected to the side of the fixed plate. A movable sleeve is threaded onto the circumferential surface of the control shaft. A connecting rod is fixedly connected to the side of the movable sleeve. A movable plate is fixedly connected to the end of the connecting rod away from the movable sleeve. A locking sleeve two is fixedly connected to the end of the movable plate away from the connecting body. A sliding groove is provided at the end of the movable plate near the connecting body. A limiting plate is fixedly connected to the circumferential surface of the locking sleeve one. The sliding groove and the limiting plate are slidably connected. The purpose of this is to ensure that the fire sprinkler head can be stably installed and to prevent loosening during use.

[0008] Furthermore, locking plates are fixedly connected to the circumferential surfaces of both locking sleeve one and locking sleeve two. A locking stud is threaded to the top of the locking plate, and a nut is threaded to one end of the locking stud that passes through the locking plate. The purpose of this is to ensure that they can be stably and firmly connected during use, thereby preventing the connection from loosening or failing due to vibration, pressure changes or other external factors.

[0009] Furthermore, an adjustment knob is fixedly connected to the end of the control shaft away from the moving sleeve, and an anti-slip block is fixedly connected to the circumferential surface of the adjustment knob. The purpose of this is to facilitate stable use by the user and prevent slippage caused by moisture.

[0010] Furthermore, there are two connecting rods, moving plates, and limiting plates, which are symmetrical to each other along the vertical central axis of the connecting body. The purpose of this symmetrical design is to distribute the connecting force and pressure evenly, ensure that each component is subjected to uniform force, and avoid connection instability or structural deformation due to force imbalance.

[0011] Furthermore, the connector is provided with a sealing mechanism, which includes an inlay groove on the inner wall of the connector. A support shaft is rotatably connected inside the inlay groove. A force-bearing plate is fixedly connected to the circumferential surface of the support shaft. A connecting block is fixedly connected to the circumferential surface of the support shaft. A sealing strip is fixedly connected to the side of the connecting block away from the support shaft. The purpose is to further improve the sealing performance between the fire sprinkler and the connector.

[0012] Furthermore, a torsion spring is fixedly connected inside the inlay groove, and one end of the torsion spring away from the inside of the inlay groove is fixedly connected to the circumferential surface of the support shaft. The purpose of this is to ensure that the support shaft can automatically reset and reduce manual intervention.

[0013] Furthermore, there are two of the inlay grooves, sealing strips, and torsion springs, which are symmetrical to each other along the vertical central axis of the connecting body. The purpose is to make the sealing range larger and improve the overall sealing performance.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model utilizes the cooperation between the control shaft, moving plate, and locking sleeve II of the connecting mechanism. When a fire sprinkler head needs to be installed using the connecting body, the operator fixes locking sleeve I and locking sleeve II to the connecting body and the sprinkler head using locking studs and nuts. Then, by rotating the adjustment knob, the control shaft is rotated, which in turn causes the moving sleeve to move along the slide track via the connecting rod, ultimately moving locking sleeve II. This securely connects the fire sprinkler head to the connecting body. This design improves installation accuracy and connection stability, ensuring the sprinkler head's firmness and safety.

[0016] 2. This utility model utilizes the interplay between components such as the inlay groove, sealing strip, and torsion spring in the sealing mechanism. When the installation end of the fire sprinkler head enters the connecting body, the force plate is pushed and rotates through the support shaft into the inlay groove. This rotation drives the connecting block and sealing strip to make them tightly contact the fire sprinkler head, eliminating gaps and enhancing sealing performance. This design improves the sealing performance of the connecting body and ensures the safe and reliable operation of the sprinkler head.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] A specific application of this embodiment is as follows: When the connector 1 is needed to install and connect the fire sprinkler head, the operator installs locking sleeve 1 2 and locking sleeve 2 45 onto the connector 1 and the fire sprinkler head respectively through locking studs 49 and nuts 410. Then, the control shaft 41 is rotated by adjusting knob 411. The rotation of control shaft 41 drives the moving sleeve 42 to move. The movement of moving sleeve 42 drives the moving plate 44 to move through connecting rod 43. During the movement of moving plate 44, it moves through sliding groove 46 in a specified displacement trajectory in limiting plate 47, thereby driving locking sleeve 2 45 to move. During the movement of locking sleeve 2 45, the fire sprinkler head moves and is embedded and connected with connector 1. When the installation end of the fire sprinkler head enters the interior of connector 1, the force plate 53 is pushed by the fire sprinkler head and rotates into the embedding groove 51 through support shaft 52. The rotation of support shaft 52 drives sealing strip 55 to rotate through connecting block 54, leaving embedding groove 51 and making close contact with fire sprinkler head, so that fire sprinkler head and connector 1 fit without gaps, improving its sealing performance.
