Description

Technical Field

[0001] This invention relates to the field of pipeline interface technology, specifically an accessory for a detachable cooling interface for protective clothing. Background Technology

[0002] Air-conditioning vests primarily utilize water pipes arranged within the vest. Liquid, cooled by an external unit, is then pumped back into the vest for circulation. In hospitals, they are mainly used by doctors or other personnel wearing protective suits. The pipes inside the vest need to pass through the protective suit to connect to the external unit. Traditional water connections often use an insertion method. This type of connection requires strong locking force to prevent detachment. Since the sealing effect is often related to the insertion depth, shallow insertion can lead to reduced sealing, while deeper insertion requires a length allowance, increasing the interface length. The interface is fixed to the back of the protective suit. If the interface is too large or too long, it becomes inconvenient to lay flat on the suit, while a vertical connection would result in excessive extension, which is impractical. If the interface is connected via a flexible hose, the hose is prone to bending during connection, reducing its lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide an accessory for a detachable cooling interface for protective clothing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An accessory for a detachable cooling interface for protective clothing includes a lower connecting plate fixedly connected to the outside of the protective clothing and an upper connecting plate connected to the water circuit of an air conditioning unit, wherein the lower connecting plate and the upper connecting plate are detachably connected.

[0006] The lower connecting plate has a central hole eccentrically opened on its surface. The surface of the lower connecting plate has two combined grooves. The combined grooves are arc-shaped, and the center of the combined grooves is concentric with the center of the central hole. The combined grooves include an arc-shaped blind groove and an open slot opened above the arc-shaped blind groove. The length of the open slot is less than the length of the arc-shaped blind groove. A drain connection hole is opened at the end of the bottom surface of the inner wall of the arc-shaped blind groove away from the open slot. Two lower connecting pipes communicating with the drain connection hole are fixedly connected to the bottom of the lower connecting plate.

[0007] The bottom of the upper connecting plate is fixedly connected to two connecting locking blocks. Each connecting locking block includes a connecting block that mates with the open slot and an arc-shaped compartment fixedly connected to the bottom of the connecting block. The bottom surface of the arc-shaped compartment has an upper water connection hole corresponding to the lower water connection hole. The top of the upper connecting plate is fixedly connected to two external connecting pipes that communicate with the upper water connection hole. The bottom surface of the upper connecting plate is fixedly connected to a positioning pin that mates with the central hole.

[0008] A locking collar is slidably connected to the outside of the upper connecting plate. When the locking collar slides to the lower position, the upper connecting plate and the lower connecting plate are surrounded by the locking collar.

[0009] As a further embodiment of the present invention: a limiting groove is provided on the periphery of the upper connecting plate, and an adjusting slider that slides in cooperation with the limiting groove is fixedly connected to the inner wall of the locking collar.

[0010] As a further embodiment of the present invention: the end of the arc-shaped blind groove is provided with an arc-shaped surface concentric with the drain connection hole, and the diameter of the drain connection hole is smaller than the diameter of the arc-shaped surface.

[0011] As a further embodiment of the present invention: the connecting block has an arc surface concentric with the lower connecting plate on the side away from the upper water channel connection hole, and the diameter of the arc surface of the upper water channel connection hole is the same as the outer diameter of the lower connecting plate.

[0012] As a further embodiment of the present invention: both the outer connecting pipe and the lower connecting pipe are L-shaped.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By utilizing eccentric rotation, the upper and lower connecting discs are locked together, ensuring a horizontal sealing area, guaranteeing the sealing length, reducing obstruction caused by length issues, and ensuring a good seal. Furthermore, the blind groove pull-out limiter, forming a rotation limiter, simplifies fixing and facilitates easy disassembly while withstanding high pull-out forces. The overall disc shape prevents discomfort from sharp edges contacting the body. Attached Figure Description

[0026] Please see Figure 1-Figure 5 Composition of the present invention

[0027] It includes a lower connecting plate 2 fixedly connected to the outside of the protective clothing and an upper connecting plate 1 connected to the water circuit of the air conditioning unit. The lower connecting plate 2 and the upper connecting plate 1 are detachably connected.

[0028] The lower connecting plate 2 is fixed to the outside of the protective suit, while the upper connecting plate 1 is connected to the main water circuit. Since the lower connecting plate 2 is a plate structure, it will not bulge outward due to its length.

[0029] The surface of the lower connecting plate 2 is eccentrically provided with a central hole 23. The surface of the lower connecting plate 2 is provided with two combined grooves 22. The combined grooves 22 are arc-shaped. The center of the combined grooves 22 is concentric with the center of the central hole 23. The combined grooves 22 include an arc-shaped blind groove 222 and an open slot 221 provided above the arc-shaped blind groove 222. The length of the open slot 221 is less than the length of the arc-shaped blind groove 222. A drain connection hole 223 is provided at the bottom of the inner wall of the arc-shaped blind groove 222 away from the open slot 221. Two lower connecting pipes 21 that communicate with the drain connection hole 223 are fixedly connected to the bottom of the lower connecting plate 2.

[0030] The bottom of the upper connecting plate 1 is fixedly connected to two connecting locking blocks 13. The connecting locking block 13 includes a connecting block 131 that cooperates with the open slot 221 and an arc-shaped compartment 132 fixedly connected to the bottom of the connecting block 131. The bottom surface of the arc-shaped compartment 132 is provided with an upper water connection hole 133 corresponding to the drain connection hole 223. The top of the upper connecting plate 1 is fixedly connected to two external connecting pipes 11. The external connecting pipes 11 are connected to the upper water connection hole 133. The bottom surface of the upper connecting plate 1 is fixedly connected to a positioning pin 14 that cooperates with the center hole 23.

[0031] The lower connecting plate 2 has a central hole 23. The central hole 23 is mainly used to cooperate with the positioning pin 14 to achieve the connection and alignment between the lower connecting plate 2 and the upper connecting plate 1. Each time the upper connecting plate 1 rotates, it will rotate around the center of the central hole 23 through the positioning pin 14. At this time, the arc-shaped cavity 132 will rotate into the combination groove 22 when the upper connecting plate 1 rotates. Since the length of the arc-shaped cavity 132 is greater than the length of the connecting block 131, the arc-shaped cavity 132 will be inserted into the arc-shaped blind groove 222. At this time, the arc-shaped blind groove 222 can only rotate out. When the joint is subjected to a pull force, it will directly form a structural limit through the arc-shaped blind groove 222 and the arc-shaped cavity 132, making the joint unable to be pulled out. Block 131 enters the open slot 221 to achieve a limit. At this time, the drain connection hole 223 will be aligned with the water supply connection hole 133. Since the arc-shaped blind groove 222 is a blind groove, a sealing layer is fixedly connected to the inner wall of the arc-shaped blind groove 222. After the arc-shaped chamber 132 enters the arc-shaped blind groove 222, the sealing layer of the arc-shaped blind groove 222 will cooperate with the arc-shaped chamber 132 to form a seal. Since the arc-shaped blind groove 222 is relatively long, the sealing length is increased to ensure the sealing performance. The liquid enters the arc-shaped chamber 132 through the external connecting pipe 11, passes through the connecting block 131, and finally enters the drain connection hole 223 through the water supply connection hole 133, and enters the cooling pipe through the lower connecting pipe 21.

[0032] A locking collar 3 is slidably connected to the outside of the upper connecting plate 1. When the locking collar 3 slides to the bottom, the upper connecting plate 1 and the lower connecting plate 2 are surrounded by the locking collar 3.

[0033] When the upper connecting plate 1 and the lower connecting plate 2 are concentric, the locking collar 3 slides downwards, connecting the upper connecting plate 1 and the lower connecting plate 2, preventing them from rotating and separating, thus achieving the purpose of locking. By rotating and locking, the sealing distance extends horizontally, ensuring sealing performance. At the same time, the resistance to pull-out force is greatly increased, and the operation is quick, the installation is convenient, and the use is stable.

[0034] A limiting groove 12 is provided on the periphery of the upper connecting plate 1, and an adjusting slider 31 that slides in cooperation with the limiting groove 12 is fixedly connected to the inner wall of the locking collar 3. Through the cooperation of the limiting groove 12 and the adjusting slider 31, the locking collar 3 can slide downward along the track, so that the locking collar 3 surrounds the joint of the upper connecting plate 1 and the lower connecting plate 2, thereby achieving the locking purpose of the upper connecting plate 1 and the lower connecting plate 2.

[0035] The end of the arc-shaped blind groove 222 is provided with an arc-shaped surface concentric with the drain connection hole 223, and the diameter of the drain connection hole 223 is smaller than the diameter of the arc-shaped surface;

[0036] Since the hole is circular, the arc-shaped surface at the end of the arc-shaped blind groove 222 can make way for the drain connection hole 223. Furthermore, the diameter of the drain connection hole 223 is smaller than the diameter of the arc-shaped surface, so that the area around the hole and the arc-shaped chamber 132 form a contact surface. Combined with the sealing effect of the sealing layer, this ensures the airtightness.

[0037] The connecting block 131 has an arc surface concentric with the lower connecting plate 2 on the side away from the upper water passage connection hole 133, and the diameter of the arc surface of the upper water passage connection hole 133 is the same as the outer diameter of the lower connecting plate 2.

[0038] Since the outer wall of the connecting block 131 has an arc surface, when the locking collar 3 slides downward, the outer wall of the connecting block 131 and the lower connecting plate 2 form a smooth circular surface. At this time, the locking collar 3 can directly act on the connecting block 131 and the lower connecting plate 2, so that the connecting block 131 and the lower connecting plate 2 always keep tightly fitted, and the connecting block 131 has no wobbling margin.

[0039] Both the outer connecting pipe 11 and the lower connecting pipe 21 are L-shaped;

[0040] The L-shaped outer connecting tube 11 and lower connecting tube 21 are mainly designed to fit the usage environment. If the outer connecting tube 11 and lower connecting tube 21 are made of flexible tubing, the tubing is prone to bending and causing water blockage. If the rigid tube is designed to be straight, it will seriously affect the comfort of the wearer. However, when the outer connecting tube 11 and lower connecting tube 21 are bent, the obstruction to the wearer is reduced.

[0041] Please see Figure 1-Figure 5 The usage process of this invention

[0042] During connection, insert the positioning pin 14 on the upper connecting plate 1 into the center hole 23. Control the upper connecting plate 1 to rotate. The upper connecting plate 1 will rotate around the center of the center hole 23 due to the limiting effect of the center hole 23 and the positioning pin 14. At this time, the connecting locking block 13 will rotate into the combination groove 22, and the arc-shaped chamber 132 will be inserted into the arc-shaped blind groove 222. The connecting block 131 will enter the open slot 221, and the upper water connection hole 133 will align with the lower water connection hole 223. The arc surface of the connecting block 131 and the arc surface of the lower connecting plate 2 form a smooth surface. At this time, the locking collar 3 is slid downward so that the locking collar 3 is located in the gap between the upper connecting plate 1 and the lower connecting plate 2. Since the adjusting slider 31 and the limiting slide groove 12 cooperate to slide, and the inner wall of the limiting slide groove 12 is provided with a damping layer, the sliding resistance of the adjusting slider 31 is increased. When the locking collar 3 is not subjected to external force, it cannot slide. At this time, the upper connecting plate 1 and the lower connecting plate 2 cannot rotate, thereby achieving the fixing effect of the upper connecting plate 1 and the lower connecting plate 2.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
