Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of catheter cleaning equipment, and particularly relates to a catheter projectile cleaning nozzle. Background Art

[0002] After the ducts of the floor heating system have been operating for a certain period, due to water quality problems and different internal pipe materials, impurities such as scale and rust are likely to form. These impurities will adhere to the inner wall of the pipe, affecting the heating effect. When cleaning the catheter, a sponge egg is placed inside the catheter. One end of the catheter is connected to a cleaning nozzle, and the cleaning nozzle is connected to a cleaning machine. The impurities attached to the inner wall of the catheter are removed by the movement of the projectile inside the catheter. However, the common size specifications of existing floor heating catheters are 16mm, 20mm, and 25mm, and different sizes of cleaning nozzles need to be replaced to clean the catheter.

[0003] For example, the cleaning nozzle disclosed in Chinese Patent Application No. CN200920219173.7 has the following specific content: A through-hole front section and a nozzle through-hole are provided at the axis of the cleaning nozzle, and the two are interconnected. Between the front section of the nozzle and the rear section of the nozzle is a nozzle middle section with a relatively thin outer diameter, and a groove is formed. Such a structure of the groove is beneficial for the hose to be fixed to the cleaning nozzle by a clamp. The outer diameter of the nozzle head is small at the front and large at the rear, showing a conical shape. The inner diameter at the frontmost spray hole of the through-hole front section is the smallest, and the inner diameter at the rearmost part is the same as the inner diameter of the nozzle through-hole. This is beneficial for the pressurization effect of air flow or liquid flow, making the fluid flowing out through the spray hole concentrated in direction and having a high ability to remove dirt. An internal thread is provided at the rear of the nozzle through-hole. Through this internal thread, the following technical problems exist:

[0004] With the integrally provided cleaning nozzle, it is difficult to fix catheters of different sizes when connecting to the catheter. Content of the Utility Model

[0005] Therefore, the embodiment of the utility model provides a catheter projectile cleaning nozzle to solve the problem that it is difficult for the existing cleaning nozzle to fix catheters of different sizes.

[0006] To achieve the above object, the embodiment of the utility model provides the following technical solutions:

[0007] A catheter projectile cleaning nozzle includes a nozzle body for limiting catheters of different sizes.

[0008] A locking component for cooperating with the nozzle body to lock the catheter is installed at the right end of the nozzle body.

[0009] The nozzle body includes a housing, and a second sealing ring for limiting conduits of different sizes is installed inside the housing. A guiding component for cooperating with the locking component to limit the conduit is installed inside the housing.

[0010] The locking component includes an annular push plate, and a plurality of special-shaped blocks for pressing against the conduit are installed on the left side of the annular push plate.

[0011] Further, a connecting sleeve is installed at the left end of the nozzle body. Internal threads are machined on the left inner wall of the connecting sleeve, and a first sealing ring is installed inside the connecting sleeve.

[0012] Further, a connecting pipe is installed at the left end of the housing. A first limiting ring block is installed at the left end of the connecting pipe, and the first limiting ring block is inside the connecting sleeve.

[0013] Further, a second limiting ring block for limiting the second sealing ring is installed inside the housing. A plurality of sliding grooves are machined on the outer wall of the right side of the housing, and a plurality of fifth clamping grooves are machined on the inner walls of the sliding grooves.

[0014] Further, a first clamping groove is machined on the right side of the second sealing ring. A second clamping groove is machined on the inner wall of the first clamping groove. A third clamping groove is machined on the inner wall of the second clamping groove. A fourth clamping groove is machined on the inner wall of the third clamping groove.

[0015] Further, the guiding component includes a limiting pipe. A plurality of connecting plates are installed at the right end of the limiting pipe. A first convex block for abutting against the inner wall of the conduit is installed at the right end of the connecting plate. An inclined surface is machined on the right side of the first convex block.

[0016] Further, a sliding rod for sliding in the cavity of the sliding groove is installed on the left side of the annular push plate. The sliding rod is an L-shaped rod body. A second convex block for engaging with the fifth clamping groove is installed at one end of the sliding rod.

[0017] Further, a clamping block for abutting against the outer wall of the conduit is installed at one end of the special-shaped block.

[0018] The embodiment of the present utility model has the following advantages:

[0019] When installing conduits of different diameters, move the conduit into the housing. The inner wall of the conduit abuts against the inclined surface, driving the plurality of connecting plates to approach each other, facilitating the conduit to approach the second sealing ring. When the inner wall of the conduit contacts the first convex block and the left end of the conduit is caught in any of the first clamping groove, the second clamping groove, the third clamping groove or the inclined surface, water leakage is avoided. Move the locking component from right to left, so that the special-shaped block drives the clamping block to press against the outer wall of the conduit. The sliding rod moves from right to left synchronously, so that the second convex block is caught in the fifth clamping groove at the left end of the sliding groove, thereby limiting the annular push plate, making the clamping block continuously press against the conduit and not easy to loosen.

[0032] Terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of clear narration, rather than to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationships shall also be regarded as the scope of implementation of the present utility model without substantial change in technical content.

[0033] Please refer to Figures 1-6 , the present utility model provides a catheter projectile cleaning nozzle, which includes a nozzle body 100 for limiting catheters 10 of different sizes.

[0034] A connecting sleeve 20 is installed at the left end of the nozzle body 100. An internal thread 21 is machined on the left inner wall of the connecting sleeve 20. A first sealing ring 22 is installed inside the connecting sleeve 20. The setting of the connecting sleeve 20 facilitates the connection between the nozzle body 100 and the projectile cleaning machine.

[0035] The nozzle body 100 includes a housing 110. A connecting pipe 111 is fixedly installed at the left end of the housing 110. A first limiting ring block 112 is fixedly installed on the outer wall of the left end of the connecting pipe 111, and the first limiting ring block 112 is inside the connecting sleeve 20. A second limiting ring block 113 for limiting a second sealing ring 120 is fixedly installed inside the housing 110, and the second sealing ring 120 is at the right end of the second limiting ring block 113.

[0036] A second sealing ring 120 for limiting catheters 10 of different sizes is installed inside the housing 110. A first groove 121 is machined on the right side of the second sealing ring 120. A second groove 122 is machined on the inner wall of the first groove 121. A third groove 123 is machined on the inner wall of the second groove 122. A fourth groove 124 is machined on the inner wall of the third groove 123. The groove diameter of the first groove 121 is larger than that of the second groove 122. The groove diameter of the second groove 122 is larger than that of the third groove 123. The groove diameter of the third groove 123 is larger than that of the fourth groove 124. The first groove 121, the second groove 122, the third groove 123 and the fourth groove 124 correspond to the diameters of catheters 10 of different sizes, so that the nozzle body 100 can be connected to catheters 10 of different sizes.

[0037] Inside the housing 110, a guiding component 130 is fixedly installed for cooperating with the locking component 200 to limit the conduit 10. The guiding component 130 includes a limiting tube 131. At the right end of the limiting tube 131, a plurality of connecting plates 132 are fixedly installed. At the right end of the connecting plates 132, a first convex block 133 for abutting against the inner wall of the conduit 10 is fixedly installed. A slope 134 is machined on the right side of the first convex block 133, which facilitates the passage of conduits 10 with different diameters through the guidance of the slope 134, so that the outer wall of the first convex block 133 abuts against the inner wall of the conduit 10.

[0038] A plurality of sliding grooves 140 are machined on the right outer wall of the housing 110, and the sliding rod 220 slides in the cavity of the sliding groove 140. A plurality of fifth clamping grooves 141 are machined on the inner wall of the sliding groove 140, and the second convex block 221 is engaged with the cavity of the fifth clamping groove 141.

[0039] At the right end of the nozzle body 100, a locking component 200 is installed for cooperating with the nozzle body 100 to lock the conduit 10. The locking component 200 includes an annular push plate 210. At the left side of the annular push plate 210, a plurality of sliding rods 220 for sliding in the cavity of the sliding groove 140 are fixedly installed. The sliding rod 220 is an L-shaped rod body. At one end of the sliding rod 220, a second convex block 221 engaged with the fifth clamping groove 141 is fixedly installed. At the left side of the annular push plate 210, a plurality of special-shaped blocks 230 for pressing against the conduit 10 are fixedly installed. At one end of the special-shaped block 230, a plurality of clamping blocks 231 for abutting against the outer wall of the conduit 10 are fixedly installed. The clamping blocks 231 are inside the housing 110, and the sliding rods 220 are outside the housing 110.

[0040] The special-shaped block 230 includes an inclined plate and a horizontal plate. The clamping block 231 is below the horizontal plate. The inclined plate abuts against the right side of the housing 110. When the special-shaped block 230 moves leftward, it drives the special-shaped block 230 to deform, causing the horizontal plate to tilt, which facilitates the clamping block 231 at the lower end of the horizontal plate to approach the outer wall of the conduit 10. Finally, the clamping block 231 abuts tightly against the outer wall of the conduit 10 to limit the conduit 10, making it difficult for the conduit 10 to fall off.

[0041] When installing catheters 10 of different diameters, the catheter 10 is moved toward the inside of the housing 110, and the inner wall of the catheter 10 contacts the inclined surface 134, driving the multiple connecting plates 132 to approach each other, so that the catheter 10 is close to the sealing ring 2 120, and the inner wall of the catheter 10 contacts the protrusion 1 133. When the left end of the catheter 10 is inserted into any groove cavity of the card slot 1 121, the card slot 2 122, the card slot 3 123 or the inclined surface 134, water leakage is avoided, and the locking assembly 200 is moved from right to left, so that the special-shaped block 230 drives the card block 231 to press the outer wall of the catheter 10, and the sliding rod 220 moves synchronously from right to left, so that the protrusion 2 221 is stuck in the card slot 5 141 at the left end of the sliding groove 140, and then the annular push plate 210 is limited, so that the card block 231 continues to press the catheter 10 and is not easy to loosen.

[0042] When the catheter 10 is disassembled and replaced with other sizes, the annular push plate 210 is pulled rightward to make the protrusion 221 slide from the groove cavity of the fifth groove 141 on the left side of the slide groove 140 to the groove cavity of the fifth groove 141 on the right side of the slide groove 140, so that the special-shaped block 230 moves to the right and away from the catheter 10, so that the catheter 10 can be disassembled and replaced.

[0043] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
