Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe connection, in particular to a quick connection structure for pipes of a water purification device. BACKGROUND

[0002] The water purification device refers to a device for producing purified water, which is mainly used in family, office, medical treatment, industry and other scenarios. With the popularity of vehicle-mounted water purification devices, the core components are connected by pipes. The reliability of pipe connection directly affects the overall operation effect of the device.

[0003] At present, the pipe connection of the vehicle-mounted water purification device mainly adopts traditional connection methods, including threaded connection, flange connection and ordinary buckle type quick connection. Although threaded connection and flange connection have certain connection strength, they need to use special tools such as wrenches and screwdrivers for installation and disassembly, which is complicated and inefficient. Although the ordinary buckle type quick connection solves the problem of assembly efficiency, it usually relies on a single buckle or elastic element to achieve limiting and fixing. During vehicle driving, multiple frequency vibrations are continuously generated, which will act on the pipe connection part for a long time. The existing quick connection structure generally lacks targeted anti-vibration design. After long-term use, due to the superposition of vibration, problems such as buckle loosening are easy to occur, which further causes water leakage, pipe deviation and even falling off, etc. It cannot meet the demand for stable operation of the water purification device during vehicle driving. In addition, the two ends of the existing connection structure are usually separately locked and limited to the pipe. The pipe may be subjected to single-sided stress due to vehicle bumping, wiring pulling and other reasons. The existing connection structure lacks stress linkage protection design. When subjected to single-sided stress, only the pipe on that side can be passively limited. Vibration will amplify the stress effect, causing stress concentration on the other side of the pipe connection part, and further causing loosening.

[0004] Therefore, it is necessary to provide a pipe quick connection structure that can improve the anti-vibration strength and avoid single-sided stress concentration. SUMMARY

[0005] Therefore, it is necessary to provide a pipe quick connection structure that can improve the anti-vibration strength and avoid single-sided stress concentration.

[0006] In order to achieve the above purpose, the following technical scheme is adopted: a quick connection structure for pipes of a water purification device, comprising: a connecting head for the butt joint of the opposite ends of two pipes, and a locking member arranged inside the two ends of the connecting head.

[0010] Preferably, the mounting portion comprises a mounting ring detachably mounted to the end of the connector, a plurality of connecting rods are mounted to the end of the mounting ring away from the connector, and a hinged ring frame is commonly mounted to the ends of the plurality of connecting rods away from the mounting ring and hinged with the plurality of rotating members.

[0011] Preferably, the rotating member is composed of a sector plate and a pushing rod, and a rubber pad is arranged on the arc surface of the sector plate.

[0012] Preferably, the clamping portion further comprises a reinforcing rod fixedly connected with the pushing rod and the outer arc surface of the arc pressing plate.

[0013] Preferably, the locking unit further comprises two locking portions symmetrically distributed and connected with the two locking sleeves, and the locking portions are used for locking and positioning the two locking sleeves.

[0014] Preferably, the pushing portion comprises two pushing plates symmetrically distributed and mounted to the inner side of the annular wall of the locking sleeve, and a pushing surface is arranged on the opposite side of the end of each pushing plate close to the axis of the locking sleeve, and the two pushing plates are located on the two sides of the corresponding pushing rod.

[0015] Preferably, the locking portion comprises two splicing plates respectively mounted to the opposite ends of the two locking sleeves, one of the splicing plates is provided with a clamping sleeve mounted to the end thereof away from the locking sleeve, a limiting through hole is formed in the side wall of the clamping sleeve away from the connector, and the other splicing plate is provided with a clamping groove.

[0016] Preferably, the locking part further comprises a clamping block slidingly connected in the clamping groove, a reset spring is installed between the clamping block and the clamping groove, and an inclined surface one and an inclined surface two are respectively arranged at an end of the clamping block away from the connector.

[0017] Preferably, an inner arc surface of the compression arc plate is paved with a rubber pad two.

[0018] Preferably, the splicing plate is detachably connected with a limiting piece.

[0019] To sum up, the present application has the following beneficial technical effects: 1. The locking unit cooperates with the two clamping units to simultaneously lock and fix the two pipe fittings, effectively improving the efficiency of the pipe fitting butt joint, and the locking unit has strong force linkage, so that when any side pipe fitting is subjected to external force pulling, the force is transmitted to the corresponding locking sleeve to promote relative movement, thereby increasing the clamping strength of the clamping part on the pipe fitting, realizing the effect of synchronous improvement of the clamping strength on both sides when one side pipe fitting is stressed, and greatly reducing the risk of falling due to stress concentration at the single pipe fitting connection.

[0020] 2.

[0032] Referring to Figure 1 , Figure 3 and Figure 5 The pipe fitting quick connection structure for water purification equipment further includes two clamping units 2 which are symmetrically connected to both ends of the connecting head 1, the clamping unit 2 includes a mounting part 20 which is detachably mounted on the end of the connecting head 1, the mounting part 20 includes a mounting ring 200 which is detachably mounted on the end of the connecting head 1, a plurality of connecting rods 201 are mounted on the end of the mounting ring 200 away from the connecting head 1, and a hinged ring frame 202 is commonly mounted on the ends of the plurality of connecting rods 201 away from the mounting ring 200.

[0033] Specifically, before the two pipe fittings are connected, the two mounting rings 200 are respectively sleeved on the two ends of the connector 1 and are fixedly connected with the connector 1 through existing buckles (not shown in the figure), the mounting ring 200 limits the articulated ring frame 202 through a plurality of connecting rods 201, and it should be noted that the spacing between the plurality of connecting rods 201 is large, so that the fingers of the operator can drive the locking member 10.

[0034] Referring to Figure 1 , Figure 3 , Figure 4 and Figure 5 , a plurality of clamping portions 21 for clamping the pipe fittings after pulling are mounted on the mounting portion 20, the clamping portion 21 comprises a rotating member 210 rotatably connected to the mounting portion 20, the rotating member 210 is composed of a sector plate and a driving rod, the articulated ring frame 202 is hingedly connected with a plurality of driving rods, and a rubber pad one is arranged on the arc surface of the sector plate; the side of the rotating member 210 close to the connector 1 is provided with a pressing arc plate 211, and the inner arc surface of the pressing arc plate 211 is provided with a rubber pad two; the clamping portion 21 further comprises a reinforcing rod 212 fixedly connected with the driving rod and the outer arc surface of the pressing arc plate 211.

[0035] Specifically, after the mounting ring 200 is mounted on the end of the connector 1, the articulated ring frame 202 simultaneously fixes the positions of the plurality of rotating members 210, and in the initial state, the plurality of driving rods are inclined away from the connector 1, and the ends of the plurality of sector plates away from the connector 1 are in a vertical state.

[0036] Referring to Figures 1-3 , the pipe fitting quick connecting structure of the water purification equipment further comprises a locking unit 3 arranged outside the connector 1 and used for locking the two clamping units 2, the locking unit 3 comprises locking sleeves 30 arranged on both sides of the connector 1 and locked with each other, and the end wall of the locking sleeve 30 is provided with a communication hole.

[0037] Referring to Figure 2 , Figure 3 and Figure 6 , the locking unit 3 further comprises two locking portions 32 symmetrically distributed, the locking portion 32 is connected with the two locking sleeves 30, and the locking portion 32 locks and limits the two locking sleeves 30; the locking portion 32 comprises two splicing plates 320 respectively mounted on the opposite ends of the two locking sleeves 30, one end of one of the splicing plates 320 away from the locking sleeve 30 is provided with a clamping sleeve 321, and the splicing plate 320 is detachably connected with a limiting member 326 through threaded cooperation.

[0038] In specific work, the splice plates 320 on the two locking sleeves 30 are the same in structure and only different in length. After the two mounting rings 200 are respectively mounted on the two ends of the connector 1, the two locking sleeves 30 are respectively sleeved on the outer sides of the two hinged ring frames 202. The splice plate 320 on one of the locking sleeves 30 is inserted into the clamping sleeve 321 at the end of the corresponding splice plate 320. The clamping sleeve 321 plays a guiding role in the insertion of the two splice plates 320. Then the limiting members 326 are respectively threadedly connected on the splice plates 320. The limiting members 326 are threaded rods. The connector 1 blocks the transverse movement of the limiting members 326, thereby avoiding the separation of the sleeved locking sleeve 30 from the connector 1.

[0039] Referring to Figure 1 , Figure 3 , Figure 6 and Figure 7 , the inside of the annular wall of the locking sleeve 30 is connected with a plurality of pushing parts 31. The pushing parts 31 include two pushing plates 310 which are symmetrically distributed and mounted on the inside of the annular wall of the locking sleeve 30. The opposite sides of the end of the two pushing plates 310 close to the axis of the locking sleeve 30 are respectively provided with pushing faces 311. The two pushing plates 310 are located on the two sides of the actuating rod. The end of the actuating rod away from the axis of the locking sleeve 30 exceeds the end of the pushing plate 310 close to the axis of the locking sleeve 30.

[0040] In specific work, the plurality of pushing parts 31 on the two sides are simultaneously driven to push and rotate the corresponding rotating members 210 during the locking and matching process of the two locking sleeves 30, so that the two pipe fittings are simultaneously moved away from the connector 1. The locking member 10 one-level clamps and positions the pipe fittings. Then the compression arc plate 211 two-level clamps and positions the pipe fittings (as shown in FIG. 8). Figure 7The two pipe fittings required to be connected are respectively inserted into the two locking members 10 from the communication holes in the middle of the two locking sleeves 30, and then pass through the locking members 10 into the connector 1. The rubber ring in the connector 1 seals the pipe fittings. Then, the two locking sleeves 30 are simultaneously pushed, and the two locking sleeves 30 simultaneously drive the plurality of push plates 310 on the two sides of the connector 1 to move towards the connector 1. The moving push plates 310 push the corresponding push rods through the pushing surfaces 311. The plurality of push rods move towards the connector 1 and drive the plurality of sector plates to rotate away from the connector 1. The plurality of sector plates drive the pipe fittings to move away from the connector 1 by a distance through the rubber pads one laid on the arc surfaces. Until the plurality of sector plates drive the rubber pads two on the plurality of compression arc plates 211 to adhere to the pipe fittings. In this process, the moving pipe fittings drive the locking members 10 to move. The triangular protrusions on the locking members 10 cooperate with the guide grooves to drive the clamping protrusions on the inner ring surface of the locking members 10 to clamp and press the pipe fittings, thereby realizing the primary clamping and positioning of the pipe fittings. The plurality of compression arc plates 211 on the same side form a circle matching the diameter of the pipe fittings. Then, the locking sleeve 30 is continuously pushed, and the plurality of compression arc plates 211 continuously press the rubber pads two, thereby increasing the clamping strength of the pipe fittings and realizing the secondary clamping and positioning of the pipe fittings. The connecting strength of the pipe fittings after connection is effectively increased, the phenomenon of the pipe fittings after connection with the connecting structural member due to long-time vibration is avoided, and the strength of the compression arc plates 211 against bending is increased by the reinforcing rods 212.

[0041] Referring to Figure 6 , the limiting through hole 322 is formed in the side wall of the clamping sleeve 321 away from the connector 1, and the clamping groove 323 is formed in the other splicing plate 320.

[0042] Referring to Figure 1 , Figure 3 , Figure 5 and Figure 6 , the locking portion 32 further includes a clamping block 324 slidingly connected in the clamping groove 323. The clamping block 324 and the clamping groove 323 are provided with a return spring 325. The end of the clamping block 324 away from the connector 1 is respectively provided with an inclined surface one and an inclined surface two.

[0043] In specific work, when the two locking sleeves 30 are spliced with each other, the two splicing plates 320 on the two sides are driven by the two locking sleeves 30 to move close to each other, the splicing plate 320 provided with the clamping groove 323 drives the clamping block 324 to move to the clamping sleeve 321 through the clamping groove 323, the inclined surface one on the clamping block 324 is in contact with the end of the clamping sleeve 321 and is stressed, so as to move into the clamping groove 323 and press the reset spring 325, until the clamping groove 323 moves to the limiting through hole 322, the reset spring 325 in the compressed state drives the clamping block 324 to reset, the clamping block 324 enters the limiting through hole 322, the splicing of the two splicing plates 320 is realized, and then the overall connection of the two locking sleeves 30 is realized, at this time, the plurality of compression arc plates 211 press the rubber pad two, and the function of clamping the pipe fittings is realized.

[0044] When the two pipe fittings are butt-jointed, only need to insert the two pipe fittings into the connector 1, and through the process of splicing the two locking sleeves 30 once, the two pipe fittings can be clamped and limited in two stages, not only the steps of fixing the two pipe fittings with the connector 1 are reduced, but also the connection strength of the two pipe fittings with the connector 1 is improved, meanwhile, when any one side pipe fitting is stressed, the two locking sleeves 30 can be applied with pulling force, so that the two locking sleeves 30 have a moving trend, the pipe fitting under stress gradually increases the clamping strength of the corresponding locking piece 10, and the locking sleeve 30 on the other side increases the pushing force on the driving lever through the plurality of pushing plates 310, so that the fan-shaped plate increases the pressure on the pipe fitting, and then the clamping strength of the pipe fitting on the other side is strengthened, so that the clamping strength of the two pipe fittings is increased when the pipe fitting on one side is stressed, the strength of the connection between the two pipe fittings and the connector 1 is further improved, and the phenomenon that the pipe fittings and the connector 1 are separated is avoided, if the pipe fittings need to be replaced, only need to press the two clamping blocks 324, the inclined surface two on the clamping block 324 is convenient for entering the clamping sleeve 321 during the separation of the two locking sleeves 30, and then the separation of the two locking sleeves 30 is facilitated, the operation is simple and convenient, and the practicability is high.
