Description

Technical Field

[0001] This utility model relates to the field of spherical heads, specifically a snap-fit ​​hemispherical head. Background Technology

[0002] Heating heat exchangers are widely used in homes and industries. They are water heaters that do not require gas, electricity, or solar energy. They are low-carbon, environmentally friendly, and energy-saving devices that use the circulating heat of the heating system to heat tap water. In heating heat exchangers, the end cap is a key component, serving as the main pressure-bearing part of the pressure vessel. As the closed end of the container, it forms a complete sealed container with the cylindrical body.

[0003] The existing hemispherical end cap, through the cooperation of the contact block and the detection block, can ensure that there is no gap between the connector and the end cap during installation, thus preventing improper operation from causing gaps between the connector and the end cap and affecting the use of the end cap.

[0004] However, the existing end caps are fastened by sealing rings and then fixed together by external bolts. Multiple bolts need to be individually twisted and engaged during disassembly or installation, which takes a lot of time and still causes inconvenience to the installation. Utility Model Content

[0005] The purpose of this utility model is to provide a snap-fit ​​hemispherical end cap, which solves the problem of existing end caps that are snapped together by sealing rings and then fixed together by external bolts. Multiple bolts need to be individually twisted and engaged during disassembly or installation, which takes a lot of time and still causes inconvenience in installation.

[0006] Therefore, this utility model provides a snap-fit ​​hemispherical end cap, including an end cap, a heat exchanger, a snap-fit ​​mechanism, and a release mechanism. The side wall of the end cap is connected to an insert tube, the heat exchanger has a slot, the side wall of the insert tube is provided with a snap-fit ​​mechanism for quickly and sealingly connecting the end cap and the heat exchanger, and the side wall of the slot is provided with a release mechanism for pushing the snap-fit ​​assembly away.

[0007] Preferably, the fastening mechanism includes a sealing groove, a sealing ring, and an inner groove. The sealing groove is formed on the side wall of the slot, the sealing ring is installed on the outer wall of the insertion tube, the inner groove is formed on the side wall of the insertion tube below the sealing ring, a retaining plate is installed in the inner groove, a side groove is formed on the side wall of the inner groove, a hydraulic rod is installed in the side groove, a first spring is fitted on the outer wall of the hydraulic rod, and a side plate is installed on the side wall of the retaining plate.

[0008] Preferably, the disengagement mechanism includes a slot, a push plate is installed in the slot, a side groove is formed on the side wall of the slot, a side plate is installed on the side wall of the push plate, and a second spring is connected to the side wall of the side plate.

[0009] Preferably, the cross-sectional dimensions of the sealing groove match the cross-sectional dimensions of the sealing ring.

[0010] Preferably, the hydraulic rod is connected to one end of the first spring, and the other end of the first spring is connected to the side wall of the side plate.

[0011] Preferably, the cross-sectional dimensions of the side plate match the cross-sectional dimensions of the side groove.

[0012] Preferably, one end of the side plate is connected to the second spring, and the other end of the second spring is connected to the side wall of the side groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention allows for quick connection between the end cap and the heat exchanger. When the end cap needs to be connected to the heat exchanger, the insert tube installed on the end cap is directly inserted into the slot. The inclined surface of the retaining plate is squeezed by the slot, generating a lateral force that moves it into the inner groove. This causes the side plate to move within the side groove, compressing the hydraulic rod and the first spring to generate potential energy. Simultaneously, the rubber sealing ring is deformed by the slot. When the sealing ring moves to the sealing groove position, it automatically rebounds and snaps into the sealing groove to achieve a sealing effect. When the inner groove aligns with the retaining groove, the retaining plate loses its pushing force, and the first spring releases its potential energy, pushing the side groove and inserting the retaining plate into the aligned retaining groove. This completes the quick connection between the end cap and the heat exchanger. When disassembly is required, simply press the push plate inward to move it towards the inside of the retaining groove. This causes the side plate to move within the side groove, compressing the second spring to generate potential energy. At the same time, the retaining plate is pushed away from the retaining groove, allowing it to enter the inner groove. Then, the end cap can be pulled outward to disassemble the insert tube from the slot, completing the quick disassembly of the end cap. This makes the assembly and disassembly of the end cap more convenient and efficient. Attached Figure Description

The side wall of the insert tube 4 is provided with a snap-fit ​​mechanism for quickly and sealingly connecting the end cap 1 and the heat exchanger 2. The side wall of the slot 3 is provided with a release mechanism for pushing the snap-fit ​​assembly away.

[0023] It should be noted that the fastening mechanism and the release mechanism in this solution improve the installation efficiency of the end cap 1.

[0024] The fastening mechanism includes a sealing groove 501, a sealing ring 502, and an inner groove 503. The sealing groove 501 is formed on the side wall of the slot 3. The sealing ring 502 is installed on the outer wall of the insertion tube 4. The inner groove 503 is formed on the side wall of the insertion tube 4 below the sealing ring 502. A retaining plate 504 is installed in the inner groove 503. A side groove 505 is formed on the side wall of the inner groove 503. A hydraulic rod 506 is installed in the side groove 505. A first spring 507 is fitted on the outer wall of the hydraulic rod 506. A side plate 508 is installed on the side wall of the retaining plate 504.

[0025] It should be noted that this solution facilitates direct insertion and fastening.

[0026] The cross-sectional dimensions of the sealing groove 501 match the cross-sectional dimensions of the sealing ring 502.

[0027] It should be noted that this solution makes the connection more airtight.

[0028] The hydraulic rod 506 is connected to one end of the first spring 507, and the other end of the first spring 507 is connected to the side wall of the side plate 508.

[0029] It should be noted that this solution allows for efficient docking or disengagement.

[0030] Example 2

[0031] Please see Figure 1-3The disengagement mechanism includes a slot 601, a push plate 602 installed in the slot 601, a side groove 603 opened on the side wall of the slot 601, a side plate 604 installed on the side wall of the push plate 602, and a second spring 605 connected to the side wall of the side plate 604.

[0032] It should be noted that this solution facilitates disassembly and removal.

[0033] The cross-sectional dimensions of the side plate 604 and the side groove 603 are consistent with each other.

[0034] It should be noted that this scheme makes the pushing process more stable.

[0035] The side plate 604 is connected to one end of the second spring 605, and the other end of the second spring 605 is connected to the side wall of the side groove 603.

[0036] It should be noted that this solution facilitates efficient detachment.

[0037] The working process and principle of this utility model are as follows: When it is necessary to connect the end cap 1 to the heat exchanger 2, the insert tube 4 installed on the end cap 1 is directly inserted into the slot 3. The inclined surface of the retaining plate 504 is squeezed by the slot 3, generating a lateral force, which moves into the inner groove 503. This causes the side plate 508 to move in the side groove 505, squeezing the hydraulic rod 506 and the first spring 507 to generate potential energy. At the same time, the rubber sealing ring 502 is deformed by the compression of the slot 3. When the sealing ring 502 moves to the position of the sealing groove 501, it automatically rebounds and locks into the sealing groove 501 to achieve a sealing effect. At the same time, when the inner groove 503 and the retaining groove 60 are connected, the sealing ring 502 is also connected to the heat exchanger 2. Once aligned, the retaining plate 504 loses its pushing force, and the first spring 507 releases its potential energy to push the side groove 508, causing the retaining plate 504 to insert into the aligned retaining groove 601, thus completing the quick connection between the end cap 1 and the heat exchanger 2. When disassembly is required, simply press the push plate 602 inward to move it towards the inside of the retaining groove 601, causing the side plate 604 to move within the side groove 603 and compress the second spring 605 to generate potential energy. At the same time, this pushes the retaining plate 504 away from the retaining groove 601, allowing the retaining plate 504 to enter the inner groove 503. Then, the end cap 1 can be pulled outward to disengage the insertion tube 4 from the slot 3, completing the quick disassembly of the end cap 1.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present invention.
