[0002] Pressurized solar water heaters are solar water heaters that use pressurized water tanks. This type of pressurized water tank can provide strong water pressure. It directly uses the water supply network pressure as the hot water outlet pressure, making the hot water pressure equal to the cold water pressure. This type of pressurized solar water heater solves the problem of low water pressure of ordinary rooftop solar water heaters that rely on gravity drop hot water.

[0003] like Figure 4 As shown, it is the structure of the pressurized solar water heater after the previous generation of assembly. The heat absorption tube is mainly fixed by buckling the longitudinal frame between the ends of the two transverse frames. However, the assembly structure of this structure has the following shortcomings in actual use: when the longitudinal frame is fixed between the ends of the two transverse frames, it is mainly fixed after assembly by means of fasteners, which requires operators to use tools to participate in the assembly process. The whole assembly process is time-consuming and laborious, which not only increases the workload and difficulty of the operator's actual installation and disassembly of the water heater structure, but also reduces the convenience and efficiency of assembling and fixing the water heater components.

[0004] In view of this, it is particularly important to design and manufacture an assembly structure that can realize tool-free and quick installation and disassembly between the longitudinal frame and the transverse frame in the actual installation, disassembly and maintenance of the pressurized solar water heater.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-3 The utility model provides a technical solution: a pressure-bearing solar water heater assembly structure, comprising a box body 1, a water receiving pipe 101 connected to the bottom of the front end and the rear end of the box body 1, a plurality of sealing buckle seats 102 equidistantly arranged at the left end and the rear end of the box body 1, a horizontal frame 3 installed on the front end and the rear end of the box body 1, a vertical frame 4 arranged between the left ends and the rear ends of the two horizontal frames 3, a limiting buckle seat 401 equidistantly fixed to the inner side of the vertical frame 4 and corresponding to the sealing buckle seat 102, and a heat absorbing tube 2 inserted between the sealing buckle seat 102 and the limiting buckle seat 401, two ends of the vertical frame 4 are symmetrically fixedly connected to one side of the horizontal frame 3, two positioning columns 403 passing through the end of the horizontal frame 3 are arranged at the end of the horizontal frame 3, and a positioning hole 304 matching the positioning column 403 is opened, and a fixing mechanism for tool-free quick assembly of the vertical frame 4 between the two horizontal frames 3 is arranged between the ends of the horizontal frame 3 and the vertical frame 4.

[0031] Specifically, Figure 1-3 As shown, the fixing mechanism includes a rotating shaft 702 rotatably installed on both ends of the longitudinal frame 4 and passing through the transverse frame 3, a central insertion hole 302 opened in the middle of the end of the transverse frame 3 and corresponding to the rotating shaft 702, and a rotary lock portion arranged between the transverse frame 3 and the rotating shaft 702, wherein the rotary lock portion includes a lock column 303 longitudinally passing through and installed between the transverse frame 3 and the central insertion hole 302, a transverse slot 703 opened in the middle of the inner end of the rotating shaft 702 and used for the lock column 303 to slide into the middle of the rotating shaft 702, and a rotary lock groove 704 opened in the middle of the rotating shaft 702 and vertically distributed with the transverse slot 703. When the lock column 303 in the central insertion hole 302 is rotated into the rotary lock groove 704 through the transverse slot 703 on the rotating shaft 702, the rotating shaft 702 is limitedly locked between the central insertion hole 302 and the lock column 303.

[0032] At the same time, the outer end of the rotating shaft 702 is equipped with a turntable 7 embedded in the end of the longitudinal frame 4, and the middle part of the outer end of the turntable 7 is integrally fixedly connected with a knob 701, and an anti-rotation part is arranged between the longitudinal frame 4 and the turntable 7, and the anti-rotation part includes a horizontal slide groove 402 opened on the outer side of the two ends of the longitudinal frame 4 and facing the turntable 7, a concave slider 5 movably installed on the inner side of the horizontal slide groove 402 and engaged with the knob 701, and a folding spring piece 6 installed between the horizontal slide groove 402 and the concave slider 5. Under normal circumstances, the folding spring piece 6 can generate an elastic extrusion force in the direction of the rotating shaft 702, so that the concave slider 5 can be engaged with the knob 701 part of the turntable 7, thereby preventing the turntable 7 from rotating accidentally.

[0033] The outer end of the concave slider 5 is integrally fixedly connected with a convex gripping block 501 , which facilitates the operator to grip and slide the concave slider 5 .

[0034] In addition, both sides of the lower ends of the two cross frames 3 are integrally fixedly connected with mounting ribs 301 in the shape of an L-shaped structure, and mounting holes are opened on the horizontal ends of the mounting ribs 301. The arrangement of the mounting ribs 301 and the mounting holes facilitates the installation and fixation of the pressurized solar water heater on the ground or other bearing surfaces by fasteners.

[0035] Working principle: When it is necessary to assemble the solar water heater structure during use, first, the operator can pre-insert and fix the open end of the heat absorbing tube 2 between the box body 1 and the sealing buckle seat 102, and then the operator can hold and turn the knob 701 on the vertical frame 4, and pre-rotate the knob 701 to a vertical state. At this time, the horizontal slot 703 on the shaft 702 will be rotated and adjusted to a horizontal state, and correspond to the lock column 303 in the central socket 302. Secondly, the operator can align the positioning column 403 on the vertical frame 4 and slide it into the positioning hole 304 on the horizontal frame 3, and align the shaft 702 on the vertical frame 4 and slide it into the horizontal position. When the end of the longitudinal frame 4 coincides with the ends of the two transverse frames 3 in the central insertion hole 302 on the transverse frame 3, the operator can hold and rotate the knob 701 90° clockwise, and the transverse slot 703 on the rotating shaft 702 will be adjusted to be perpendicular to the locking column 303, and the locking column 303 will enter the rotary lock slot 704 on the rotating shaft 702. At this time, the rotating shaft 702 is locked and fixed between the central insertion hole 302 and the locking column 303. Finally, under the action of the elastic force of the folded spring sheet 6, the concave slider 5 in the transverse slide groove 402 can be elastically buckled to the knob 701 on the rotary disk 7, thereby preventing the rotating shaft 702 from rotating accidentally after the rotation adjustment.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
