DETAILED DESCRIPTION

[0021] The following is a further description of the present invention in conjunction with specific embodiments. These embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0022] See also Figures 1 to 3 This is the structure view, bottom structure view, Figure 1 A partial enlarged view at point A in the middle shows a collector header end cover assembly device, which includes a base plate 1, bottom brackets 2 are connected to the bottom of both sides of the base plate 1, a slide groove 3 is opened on the base plate 1, and two symmetrically arranged limit frames 5 are connected to the upper end surface of the base plate 1 and the two sides of the slide groove 3 by bolts, and rounded corners are arranged at the top edges of the opposite end surfaces of the two limit frames 5, a pad 4 is arranged between the limit frames 5 and at the upper end surface of the base plate 1, a collector header is arranged between the two limit frames 5, the bottom of the collector header contacts with the pad 4, the shape and structure of the limit frames 5 are designed to fit the outer shell of the collector header, and an arc structure is arranged on the top of the collector header, and when cooperating with the limit frames 5, the top arc structure is inverted downward, and the flange structures at both ends of the collector just contact with the upper end surfaces of the limit frames 5, which can maintain the stability of the collector where you want to place it.

[0023] Two symmetrically arranged vertical plates 7 are respectively connected to the two ends of the lower end surface of the substrate 1. A screw rod 9 is rotatably arranged between the vertical plates 7 through bearings and retaining springs. A hand wheel 10 is fixedly arranged on the outside of one end of the rod. Two symmetrically distributed sliders 8 are slidably arranged on the inner side of the slide groove 3. A threaded sleeve is fixedly arranged on the inner side of the slider 8. The threaded sleeve is threadedly matched with the screw rod 9. The threads at both ends of the screw rod 9 are opposite. When the screw rod 9 rotates, the movement directions of the two sliders 8 are opposite. There is a clearance fit between the side walls of the slider 8 and the side walls of the slide groove 3, and the spacing is not greater than 0.5mm. A bracket 6 is arranged on the upper end of the slider 8. The slider 8 can slide along the axis of the screw rod 9 and the inner side of the slide groove 3 as the threaded sleeve acts on the inner side of the slide groove 3 when the screw rod 9 rotates. Because the threads at both ends of the screw rod 9 are opposite, the two sliders 8 will drive the two brackets 6 to move toward each other or in opposite directions, and the upper end surface of the bottom substrate 1 of the bracket 6 slides.

[0024] The bottom of the back of the bracket 6 is connected to a connecting frame 11, which is connected to the slider 8 by bolts. Receiving grooves 12 are provided on the side walls at both ends of the bracket 6, and magnets 13 are provided inside the receiving grooves 12. The bottom of the magnet 13 is rotatably arranged with the receiving grooves 12 through a pin 14. The magnet 13 is a bar-shaped structure and has rounded corners at both ends. The upper end height of the magnet 13 is higher than the upper end face height of the bracket 6. The side wall of the magnet 13 close to the bracket 6 is adsorbed and fitted with the side wall of the receiving groove 12. The cross section of the receiving groove 12 is trapezoidal and the side close to the bracket 6 is the short side. The front end face of the bracket 6 is provided with The mounting groove 15 has a center hole 16 penetrating the bracket 6 in the middle thereof. The shape of the mounting groove 15 is designed according to the shape of the end cover, so that the portion of the end cover opposite to the flange structure can be arranged inside the mounting groove 15. The magnet 13 contacts the bracket 6, transfers the magnetic force to the contacted portion, and adsorbs the side wall of the end cover arranged inside to keep it in contact with the bracket 6 as much as possible. If the side wall of the end cover is severely deformed, in addition to the manual reset method, the magnet 13 can also be used for adsorption to expand the side wall of the end cover as much as possible.

[0025] By manually turning the hand wheel 10, the slider 8 can be controlled to drive the bracket 6 toward the collector header, and through the cooperation of the limit frame 5 and the bracket 6, the end cover can be matched with the collector header according to the set line. The center hole 16 can pass through the water pipe at the end of the collector header. After the end cover is plugged into the end of the collector header, continuously turning the hand wheel 10 can continuously pressurize the end cover to further assemble it into place, saving time and effort.

[0026] When the assembly is completed, the bracket 6 can be moved away from the collector header by shaking the hand wheel 10 in the opposite direction. However, at this time, the magnet 13 still remains adsorbed with the bracket 6 and is magnetically attracting the end cover. Moving the bracket 6 will inevitably change the assembly relationship between the end cover and the collector header. Therefore, when the bracket 6 is reset, the magnet 13 needs to be manually flipped away from the bracket 6 to make the bracket 6 lose its strong magnetic force and can no longer attract the end cover. At this time, the hand wheel 10 is shaken to make the bracket 6 move away from the collector header driven by the slider 8.

[0027] In order to save time and improve efficiency when installing and placing the collector header, a scale ruler is engraved on the upper end surface of the base plate 1 near the bottom edge of the limit frame 5, which is conducive to quickly placing the collector header with reference to the scale ruler.

[0028] The utility model adopts a bracket 6 with a magnet 13 to place the end cover, and the side walls on both sides of the end cover are adsorbed by the magnetic force of the magnet 13 to make it fit as close as possible with the inner wall of the bracket 6, and the screw rod 9 is controlled by the hand wheel 10 to drive the slider 8 to be assembled inwardly from both ends at the same time, which saves time and labor, realizes mechanical assisted installation, improves assembly efficiency and reduces labor intensity, and the magnet 13 adsorbs the side wall of the end cover to reduce the difficulty of assembly.
