Description

Technical Field

[0001] This utility model relates to the field of corrugated metal hose technology, specifically to a high-pressure resistant corrugated metal hose. Background Technology

[0002] Corrugated metal hose is a flexible pipe made of stainless steel or other metal materials. It has a unique corrugated structure and is usually composed of three parts: corrugated pipe, braided sleeve and connector. The corrugated pipe is the core component. Its corrugated pipe wall design allows the hose to bend flexibly within a certain range to adapt to connection needs in different directions.

[0003] A search revealed that patent document CN220727399U discloses a high-pressure resistant corrugated metal hose. When hose A and hose B need to be connected, the connection point is sealed only with a rubber gasket, which has the problem of limited sealing effect. By setting a sealing mechanism at the connection point of hose A and hose B, the sealing effect between the two is increased while ensuring convenient connection, thus ensuring stability.

[0004] However, the connection between the above-mentioned hoses still uses threaded connection. Threaded connection requires one side of the hose to be rotated during the connection process. When the overall length of the hose to be connected is long, the operator needs to spend a lot of labor to complete the rotation of the hose, which increases the complexity of the connection between the hoses. Utility Model Content

[0005] In view of the problems existing in the current high-pressure resistant corrugated metal hoses, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a high-pressure resistant corrugated metal hose, which solves the problem of the cumbersome method of connecting two long hoses by threaded rotation.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-pressure resistant corrugated metal hose includes a first hose and a second hose. A first collar and a second collar are respectively fixedly sleeved at one end of the first hose and the second hose. A plurality of symmetrically arranged clamping plates are fixedly provided on the outer wall of the second collar. A plurality of symmetrically arranged clamping grooves are opened on the outer wall of the first collar. The ends of the clamping plates are inserted into the clamping grooves.

[0009] Each of the card slots is equipped with a push-separation mechanism, which is used to push the card plate away from the card slot.

[0010] Preferably, the lower side of the end of the card plate near the first ring is inclined.

[0011] Preferably, the pushing separation mechanism includes a push plate, one end of which is located in the slot, and a support rod is rotatably inserted inside the push plate. Both ends of the support rod are fixedly fitted with support plates, and the support plates are fixedly disposed on the outer wall of the first hose.

[0012] Preferably, a push ring is slidably sleeved on the outer side of the first hose, and a push inclined surface is formed on the inner wall of the push ring, the push inclined surface being in contact with the end of the push plate away from the clamping plate;

[0013] A return spring is fixed between the push ring and the first hose, and the return spring is sleeved on the outside of the first hose.

[0014] Furthermore, a sealing ring is fixedly provided at one end of the second hose near the first hose, and the sealing ring contacts and engages with the inner wall of the first hose.

[0015] Preferably, the card is a flexible plastic card.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model, through the provision of a first set of rings, a second set of rings, a locking plate, and a locking groove, enables quick-connection of two adjacent hoses by setting a locking plate and locking groove on the outside of the corrugated metal hose, thereby improving the connection effect of the corrugated metal hose. At the same time, it can ensure the stability of the hose connection and make the hose connection have stable pressure resistance.

[0018] 2. This utility model, through the provision of a first set of rings, a slot, a push plate, and a pushing separation mechanism, enables multiple push plates to push the card plate, causing the card plate to separate from the slot, thus completing the rapid separation between two adjacent hoses.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a high-pressure resistant corrugated metal hose.

[0027] This utility model provides, for example Figure 1-3 The high-pressure resistant corrugated metal hose shown includes a first hose 1 and a second hose 2. A sealing ring 13 is fixedly provided at one end of the second hose 2 near the first hose 1. The sealing ring 13 contacts and engages with the inner wall of the first hose 1. A first collar 3 and a second collar 4 are respectively fixedly sleeved at one end of the first hose 1 and the second hose 2. A plurality of symmetrically arranged retaining plates 5 are fixedly provided on the outer wall of the second collar 4. The retaining plates 5 are elastic plastic retaining plates. A plurality of symmetrically arranged retaining grooves 6 are opened on the outer wall of the first collar 3. The ends of the retaining plates 5 are inserted into the retaining grooves 6. The lower side of the retaining plate 5 near the first collar 3 is inclined.

[0028] When connecting two adjacent corrugated metal hoses, the first hose 2 and the second hose 2 are brought closer together, and the first collar 3 and the second collar 4 are brought closer together. During the movement of the second collar 4, the inclined surface of the clamping plate 5 begins to contact the side of the first collar 3. Since the clamping plate 5 is an elastic plastic clamping plate, it can be pushed and slide on the outer wall of the first collar 3. When the sealing ring 13 is inserted into the first hose 1, the first hose 1 and the second hose 2 are inserted and positioned. The clamping plate 5 can be inserted into the groove 6 under its own elastic recovery. At this time, the contact between the clamping plate 5 and the vertical surface of the inner wall of the groove 6 can complete the quick clamping and positioning between the two hoses.

[0029] In order to enable the two hoses to be quickly separated after connection, such as Figure 1-3As shown, each slot 6 is equipped with a pushing separation mechanism inside. The pushing separation mechanism is used to push the card plate 5 away from the slot 6. The pushing separation mechanism includes a push plate 7. One end of the push plate 7 is located inside the slot 6. A support rod 8 is rotatably passed through the inside of the push plate 7. Both ends of the support rod 8 are fixedly sleeved with support plates 9. The support plates 9 are fixedly installed on the outer wall of the first hose 1. A pushing ring 10 is slidably sleeved on the outer side of the first hose 1. A pushing inclined surface 11 is opened on the inner wall of the pushing ring 10. The pushing inclined surface 11 contacts and cooperates with the end of the push plate 7 away from the card plate 5.

[0030] A return spring 12 is fixed between the push ring 10 and the first hose 1, and the return spring 12 is sleeved on the outside of the first hose 1.

[0031] When it is necessary to separate the two hoses, the push ring 10 can be pushed laterally, so that the push slope 11 on the inner wall of the push ring 10 can push the ends of the multiple push plates 7, so that the end of the push plate 7 near the push ring 10 is squeezed and moves. At this time, under the support of the support rod 8, the end of the push plate 7 away from the push ring 10 tilts upward and pushes the clamping plate 5, so that the clamping plate 5 can be separated from the clamping groove 6. At this time, the two hoses can move away from each other and the disassembly is completed.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
