Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of quick connectors, and more particularly to a high temperature resistant quick connector. Background Art
[0002] In autoclaves or pressure vessels, the existing quick connectors can be used normally at room temperature and pressure, but when the temperature exceeds 250°C, the quick connector seal fails, causing product quality problems. At 300°C and above, using foreign brand products will result in high product cost and long procurement cycle time. Existing quick connectors all use rubber seals and F4 seals. They can only be used at lower temperatures and cannot meet high temperatures and high pressures. Therefore, we provide a high temperature resistant quick connector. Summary of the invention
[0003] The purpose of the present invention is to provide a high temperature resistant quick connector to solve the problems raised in the above background technology: Existing quick connectors all use rubber seals and F4 seals, which can only be used at relatively low temperatures and cannot meet the requirements of high temperature and high pressure.
[0004] In order to achieve the above object, the present invention provides the following technical solutions: A high-temperature resistant quick connector comprises a shell, an end face bearing is fixedly connected to the interior of the shell, a nozzle is slidably connected to the interior of the end face bearing, a first connector is fixedly connected to the outer end of the nozzle away from the shell, a second connector is detachably connected to the interior of the shell, a blind hole is provided inside the second connector, a baffle is provided inside the blind hole, the baffle is fixedly connected to the second connector, a slot is provided inside the shell, and the slot cooperates with the baffle.
[0005] Preferably, the outer side wall of the nozzle is in contact with the inner side wall of the end bearing.
[0006] Preferably, the card slot is an L-shaped structure.
[0007] Preferably, there are two blind holes, and the two blind holes are symmetrically distributed.
[0008] Preferably, a baffle is sleeved on a side of the outside of the nozzle away from the first joint, the baffle is fixedly connected to the nozzle, and a spring is sleeved on the outside of the nozzle and located between the baffle and the end face bearing.
[0009] Preferably, a ball head is fixedly connected to a side of the second joint outside close to the nozzle, and a conical surface is provided inside the nozzle, and the conical surface is used in conjunction with the ball head.
[0010] Compared with the prior art, the present invention has the following beneficial effects: The second joint is inserted into the shell, the nozzle squeezes the spring through the baffle, and the baffle on the second joint enters the slot on the shell, and then rotates slightly. Finally, after releasing the hand, the elastic force of the squeezed spring will drive the nozzle to reset, so that the baffle is engaged with the slot, and the ball head fits with the cone surface. The connection is fast and effective, and the maintenance is easy. In the autoclave or pressure vessel, the quick connector can be quickly connected, can compensate for the changes in temperature and pressure in the autoclave or pressure vessel, maintain good sealing performance, and is resistant to high temperature and high pressure.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0014] See also Figures 1 to 5 A high temperature resistant quick connector comprises a shell 1, an end bearing 2 is fixedly connected to the inside of the shell 1, a nozzle 3 is slidably connected to the inside of the end bearing 2, a first connector 4 is fixedly connected to the outside of the nozzle 3 away from the shell 1, a second connector 7 is detachably connected to the inside of the shell 1, the outside of the second connector 7 and the first connector 4 are both regular hexagonal structures for conveniently screwing them with a wrench, a blind hole 8 is provided in the inside of the second connector 7, a baffle rod 9 is provided in the inside of the blind hole 8, the baffle rod 9 is fixedly connected to the second connector 7, a slot 10 is provided in the inside of the shell 1, the slot 10 is used in conjunction with the baffle rod 9, and the second connector 7 and the shell 1 are connected through the baffle rod 9 and the slot 10.
[0015] Furthermore, the outer wall of the nozzle 3 fits with the inner wall of the end bearing 2, the outer ring of the end bearing 2 is connected and fixed to the housing 1, and the nozzle 3 slides inside the inner ring of the end bearing 2, and the nozzle 3 is supported by the end bearing 2 to ensure the stability of the nozzle 3.
[0016] Furthermore, the slot 10 is an L-shaped structure. When the blocking rod 9 is engaged with the slot 10 of the L-shaped structure, the connection and fixation between the second joint 7 and the housing 1 can be achieved.
[0017] Furthermore, there are two blind holes 8 , which are symmetrically distributed on both sides of the second connector 7 , and are used to cooperate with the card slot 10 to connect the second connector 7 and the housing 1 .
[0018] Furthermore, a baffle 5 is sleeved on the side of the outside of the nozzle 3 away from the first joint 4, and the baffle 5 is fixedly connected to the nozzle 3. A spring 6 is sleeved on the outside of the nozzle 3 and located between the baffle 5 and the end face bearing 2. After the second joint 7 is inserted into the outer shell 1, it will push the nozzle 3, and the nozzle 3 will squeeze the spring 6 through the baffle 5. When the baffle rod 9 is engaged with the slot 10, the elastic force of the compressed spring 6 will drive the nozzle 3 to reset.
[0019] Furthermore, a ball head 11 is fixedly connected to the outside of the second joint 7 on one side close to the nozzle 3, and a conical surface 12 is provided inside the nozzle 3. The conical surface 12 is used in conjunction with the ball head 11 to connect the second joint 7 and the nozzle 3 through the ball head 11 and the conical surface 12. Due to the elastic force of the spring 6, the ball head 11 can be tightly pressed against the conical surface 12.
[0020] The use steps of the present invention are as follows: when the high-temperature resistant quick connector is in use, the second connector 7 is inserted into the housing 1. During the process, the ball head 11 on the second connector 7 will enter into the conical surface 12 on the nozzle 3. At the same time, the second connector 7 will push the nozzle 3 to move. The nozzle 3 then squeezes the spring 6 through the baffle 5. At the same time, the baffle rod 9 on the second connector 7 enters into the slot 10 on the housing 1 and then rotates slightly. Finally, after letting go, the elastic force of the squeezed spring 6 will drive the nozzle 3 to reset, so that the baffle rod 9 is engaged with the slot 10, and the ball head 11 is combined with the conical surface 12. The connection is fast and effective, and maintenance is easy. In an autoclave or pressure vessel, the quick connector can be quickly connected, can compensate for changes in temperature and pressure in the autoclave or pressure vessel, maintain good sealing performance, and is resistant to high temperature and high pressure.
