With reference to 1 and 2 has a clamping device according to the invention for Roof tiles have a first clamping unit 205, a second clamping unit 204 and an adjusting screw 501.

According to 1 and 5 The first clamping unit 205 according to the invention has a first clamping part 2052 which is provided for engaging in a groove 101 on one side of the rail 100. The specific design of the first clamping part 2052 should be adapted to the shape of the corresponding groove 101, so that the rail 100 can be fixed by the first clamping part 2052 snapping into the associated groove 101. A through hole 2053 is provided on the first clamping unit 205, which facilitates the connection to the second clamping unit 204.

With reference to 6 the second clamping unit 204 includes a second clamping part 2042 which serves to engage in a groove 101 on the opposite side of the rail 100. The specific configuration of the second clamping part 2042 should also correspond to the shape of the associated groove 101 so that the rail 100 can be secured by the engagement of the second clamping part 2042 in the corresponding slot 101. A screw opening is provided on the second clamping unit 204.

As in 2 As shown, the adjusting screw 501 penetrates the through hole 2053 and enters the screw hole to adjust the distance between the first clamping part 2052 and the second clamping part 2042. By adjusting the penetration depth of the adjusting screw 501 into the screw hole, the distance between the first clamping part 2052 and the second clamping part 2042 can be varied, which simplifies the installation of the rail 100.

The roof tile clamping device according to the invention comprises a first clamping unit 205 and a second clamping unit 204 which are separate from each other. The adjusting screw 501 penetrates the through hole 2053 of the first clamping unit 205 and engages the thread of the first screw hole of the second clamping unit 204. By regulating the penetration depth of the adjusting screw 501 into the first screw hole, the distance between the first clamping part 2052 and the second clamping part 2042 can be adjusted. When installing the rail 100, the adjusting screw 501 can adjust the distance between the first clamping part 2052 and the second clamping part 2042 to be larger than the width of the bottom of the rail 100 [i.e., the side with the groove 101]. After that, the bottom of the rail 100 with the groove 101 can be easily placed between the first clamping part 2052 and the second clamping part 2042. Then, by turning the adjusting screw 501, the distance between the first clamping part 2052 and the second clamping part 2042 is reduced until both clamping parts engage the groove 101 on the underside of the rail 100, which completes the connection of the rail 100 to the roof tile clamping device. This invention allows the rail 100 to be attached by simply placing it between the first clamping part 2052 and the second clamping part 2042 and tightening the adjusting screw 501, which ensures easy and quick installation.

The detailed design of the clamping device for roof tiles is described below.

With reference to 5 the first clamping unit 205 has a mounting plate 251 and a support strut 252 connected thereto. The support strut 252 and the mounting plate 251 can be constructed as a unit or connected to each other by fasteners or welding. The first clamping part 2052 is arranged on the side of the mounting plate 251 which faces away from the support strut 252, while the through hole 2053 is positioned on the mounting plate 251.

Further, with reference to 6 , the second clamping unit 204 has a stop bar 242 connected to a support plate 241 located on the first side of the stop bar 242. The stop bar 242 and the support plate 241 are typically in a vertical relationship to one another. The second clamping part 2042 is located on the support plate 241, on the side facing away from the stop bar 242, so as to provide a larger support surface. When assembling the rail 100, it can first be positioned on the support plate 241. The stop bar 242 rests on the support strut 252 on the other side, with the first screw hole formed in the stop bar 242. Once positioned on the support strut 252, the support plate 241 can be designed to be vertical with respect to the mounting plate 251.

In order to increase the clamping effect of the first clamping unit 205 and the second clamping unit 204 on the rail 100, in this embodiment the side of the support strut 252 facing the first clamping part 2052 is provided with an inclined surface 2051. The inclined surface 2051 slopes away from the side connected to the fastening plate 251, towards a direction facing away from the first clamping part 2052. The stop bar 242 is supported on this inclined surface 2051. As in 7 As shown, when assembling the rail 100, first the end of the rail 100, which has the groove 101 is placed on the support plate 241 so that the groove 101 is positioned between the first clamping part 2052 and the second clamping part 2042. By turning the adjusting screw 501, the first clamping part 2052 and the second clamping part 2042 are gradually brought closer to each other. As the stop bar 242 moves along the inclined surface 2051 and slides towards the fastening plate 251, it also rises due to the inclined surface 2051 until the first clamping part 2052 and the second clamping part 2042 engage in the groove 101 on the bottom of the rail 100. At the same time, the support plate 241 presses the bottom of the rail 100 firmly against the first clamping part 2052 [see 8th ].

In order to increase the stability of the stop bar 242 when sliding on the inclined surface 2051, the side of the stop bar 242 facing the inclined surface 2051 is an inclined surface 2041 that rests on the inclined surface 2051. When the inclined surface 2051 and the inclined surface 2041 meet, the mounting plate 251 and the stop bar 242 are parallel to each other. The inclination angle of the inclined surface 2051 and the inclined surface 2041 is identical, which ensures that the mounting plate 251 and the stop bar 242 always remain parallel during the sliding process on the inclined surface 2051.

In order to prevent loosening during transport and use and at the same time to stabilize the distance between the first clamping unit 205 and the second clamping unit 204 in order to be able to insert the rail 100 more easily, the clamping device for roof tiles according to the invention can also have a spring element 206 arranged between the fastening plate 251 and the stop bar 242. In this exemplary embodiment, the spring element 206 can be designed as a compression spring arranged around the adjusting screw 501. Under the action of the spring element 206, a larger distance between the first clamping unit 205 and the second clamping unit 204 can be ensured before the adjusting screw 501 is tightened, which facilitates the installation of the rail 100. In addition, the spring element 206 can prevent the assembled unit from loosening during transport and use.

The mentioned first through hole 2053 is designed as an elongated hole whose longitudinal direction points in the direction of the first clamping part 2052. This enables an adjustment of the vertical position between the first clamping unit 205 and the second clamping unit 204 in order to adjust the clamping force of the support plate 241 on the bottom of the rail 100 against the first clamping part 2052.

As in 1 until 3 As shown, the invention further discloses a roof tile hook 200 comprising a hook main body 202, a mounting base 201 and the roof tile clamping device described above. The hook main body 202 can be bent into an appropriate shape structure according to requirements. In this embodiment, the specific shape of the hook main body 202 is not limited. The mounting base 201 is arranged at one end of the hook main body 202, with the first clamping unit 205 positioned at the other end of the hook main body 202.

By integrating the roof tile clamping device, the roof tile clamping device 200 disclosed in the present invention has all the technical features of the said roof tile clamping device, which are not further explained here.

The specific implementation of the roof tile hook 200 is explained below.

The first clamping unit 205 is attached to the hook main body 202 by means of the connecting bracket 203. As shown in 4 As shown, the connecting bracket 203 has a base plate 223 attached to the hook main body 202 and a standing plate 213. On the standing plate 213 there is a second through hole 2031 through which the adjusting screw 501 is guided. The base plate 223 and the standing plate 213 are manufactured as a single piece. The adjusting screw 501, which is guided through the second through hole 2031 and the first through hole 2053 and cooperates with the thread of the first screw hole, enables the clamping device according to the invention for roof tile hooks to be mounted on the hook main body 202 by means of the connecting bracket 203.

Furthermore, the second through hole 2031 is an elongated hole perpendicular to the base plate 223 in the longitudinal direction, whereby the height of the roof tile hook clamping device can be adjusted to suit different roof structures and facilitate the height adjustment of the rail 100 on the roof.

In order to increase the stability of the connection between the clamping device for roof tile hooks and the base plate 223, a first toothed strip 2033 is attached to the side of the surface of the standing plate 213 that is in contact with the fastening plate 251. On the side of the surface of the fastening plate 251 that is in contact with the standing plate 213, there is a second toothed strip 2054 that engages in the first toothed strip 2033. Under the action of the spring element 206, the second toothed strip 2054 of the fastening plate always engages into the first toothed strip 2033 of the upright plate 213 to prevent the fastening plate from slipping along the upright plate 213. To adjust the height of the clamping device for roof tile hooks, the first clamping unit 205 is pulled outwards so that the second toothed strip 2054 of the first clamping unit 205 is released from the first toothed strip 2033 of the upright plate 213. This allows the vertical position of the first clamping unit 205 and the second clamping unit 204 to be adjusted. After adjusting the vertical position and releasing, the first clamping unit 205 and the second clamping unit 204 can press the second toothed strip 2054 of the first clamping unit 205 firmly against the first toothed strip 2033 by compressing the spring element 206 to prevent slipping.

The base plate 223 can be fixed to the hook main body 202 by means of the base plate screw set 300. A third through hole 2032 is provided on the base plate 223, while a second screw hole 2021 is formed on the hook main body 202. The base plate locking screw 301 of the base plate screw set 300 is passed through the third through hole 2032 and engages the thread of the second screw hole 2021. A corresponding base plate fixing disk 302 can be placed on the base plate locking screw 301 to ensure a tight fit and prevent loosening. The third through hole 2032 can be designed as an elongated hole that runs towards the clamping device for roof tile hooks in order to make the position of the connecting angle 203 adjustable. In addition, the connecting bracket 203 can rotate about the locking screw 301 to allow adjustment of the direction of the rail.

The mounting base 201 is fixed to the hook main body 202 by means of the mounting base screw set 400. A fourth through hole 2011 is provided on the mounting base 201, while a fifth through hole 2022 is provided on the hook main body 202. The mounting base screw set 400 includes a mounting base screw 401 and a U-shaped clamp block 403, and a third screw hole 4031 is provided on the U-shaped clamp block 403. The side walls of the U-shaped clamp block 403 are provided on both sides of the hook main body 202, and the mounting base screw 401 is passed through the fourth through hole 2011, the fifth through hole 2022, and the third screw hole 4031 and engages the thread. The side walls of the U-shaped clamp block 403 clamp onto the sides of the lower end of the hook main body 202, which prevents the U-shaped clamp block 403 from twisting when tightening the mounting base screw 401. In addition, the large contact area between the U-shaped clamp block 403 and the lower part of the hook main body 202 increases the stability and reduces the deformation of the lower part of the hook main body 202.

In addition, a corresponding mounting base fixing washer 402 can be placed on the mounting base screw 401 to ensure a tight fit and prevent loosening.

The fourth through hole 2011 and the fifth through hole 2022 may be designed as elongated holes extending in the vertical direction to enable height adjustment of the hook main body 202.

The illustrated embodiments and drawings are not intended to limit the form and embodiment of the invention. Any reasonable adaptations or modifications made by those skilled in the art should be considered to be within the scope of the present invention.
