Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a track clamping block. Background Technology

[0002] In common photovoltaic systems, the C-shaped steel purlin 1' and the inclined beam 2' are fixed in the following way: Figure 1 As shown, purlin support plates 3' and stiffening plates 4' need to be welded onto the inclined beam, and then bolts 5' are used to lock them to the pre-drilled holes on the C-shaped steel. The disadvantages of this approach are: the purlin support plates and stiffening plates need to be welded in advance, the C-shaped steel needs to be pre-drilled, it is difficult to adjust on site, and the processing is troublesome.

[0003] Therefore, a fixing block for a photovoltaic panel guide rail, as disclosed in Chinese Patent CN 220935098 U, allows for the locking of two C-shaped steel sections by simply opening mounting holes on the horizontal part of the flange of one C-shaped steel section; however, this solution has poor structural stability. This utility model proposes a different type of rail fixing block, unlike the aforementioned one, but which still achieves rapid installation and fixing of C-shaped steel sections. Utility Model Content

[0004] The purpose of this utility model is to provide a track pressure block that has the advantages of convenient installation and fixing of two horizontally and vertically arranged C-shaped steels, and better structural stability.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A track clamping block includes a clamping block body and a connecting component;

[0007] The pressing block body includes a base plate and two side plates. The two side plates are erected above the front and rear edges of the base plate at intervals, and an installation space is formed between the two side plates.

[0008] The bottom surface of the middle part of the pressure block body forms a slot that extends upward and connects to the installation space. The slot includes a bottom slot located on the bottom plate and a side slot located on the side plate. The slot is used to avoid and engage the end hook of the wing plate of the C-shaped steel rail.

[0009] A snap-fit ​​part is formed on the left side of the slot of the pressure block body, and the left and right widths of the snap-fit ​​part match the depth of the C-shaped steel of the track.

[0010] A locking part is formed on the right side of the slot of the pressure block body. The bottom plate of the locking part is provided with a vertically penetrating connecting hole. The connecting hole is used to connect with the pre-drilled mounting hole on the wing plate of the inclined beam C-shaped steel. The locking part and the inclined beam C-shaped steel are pressed and fixed by a connector passing through the connecting hole and the mounting hole.

[0011] Furthermore, the connector includes screws and nuts.

[0012] Furthermore, the side groove of the slot is a wedge-shaped groove with a wider bottom, and an inclined abutment edge is formed on the left side of the side groove; this abutment edge is used to press against the hook part of the C-shaped steel of the track.

[0013] Furthermore, the bottom of the locking part has a protruding pressing rib, which is located on the right side of the connecting hole.

[0014] Furthermore, at least two slots are provided in the middle of the pressing block body, with each slot spaced apart from the left and right, and each slot and the left end of the pressing block body forming a locking part with different widths on the left and right sides.

[0015] Furthermore, the top width of the snap-fit ​​portion is adapted to the depth of the C-shaped steel of the track, while the bottom width is designed to taper.

[0016] Furthermore, the tops of the two side plates of the locking part are configured as bevels with the left side higher than the right side.

[0017] After adopting the above technical solution, the track C-shaped steel is usually arranged in the front-to-back direction with the flange facing down and overlapped on the inclined beam C-shaped steel arranged in the left-to-right direction with the flange facing up. When fixing the two, firstly, the left side of the clamping part of the pressure block body is inserted into the C-shaped opening of the track C-shaped steel, and the left end of the clamping part abuts against the web of the track C-shaped steel. The groove in the middle of the pressure block body is for the hook part of the track C-shaped steel to pass through and avoid. Then, ensure that the connecting hole of the locking part of the pressure block body is aligned with the mounting hole of the inclined beam C-shaped steel. Then, use the connector to pass through the connecting hole and mounting hole to lock the locking part of the pressure block body and the inclined beam C-shaped steel. At this time, the clamping part of the pressure block body will also press and fix the lower flange of the track C-shaped steel to the inclined beam C-shaped steel.

[0018] The pressure block of this invention has a simple and lightweight structure, is easy to install, requires no welding, and its locking part can firmly clamp the C-shaped steel of the track. Compared with the pressure blocks of the prior art, which cannot abut against the web of the C-shaped steel of the track and cannot provide support in the opposite direction to the deformation trend of the C-shaped steel, the locking part of this invention abuts against the web of the C-shaped steel of the track and can provide support in the opposite direction to the deformation trend of the C-shaped steel, effectively reducing the deformation of the C-shaped steel. At the same time, the contact area between the pressure block and the flange of the C-shaped steel of the prior art is small, resulting in poor structural stability, while the bottom plate of the locking part of this invention has a large contact area with the flange of the C-shaped steel of the track, resulting in a more stable structure. The slot allows the C-shaped steel of the track to move back and forth for adjustment, and the locking part, after locking with the inclined beam C-shaped steel, ensures the fixing effect of the locking part on the C-shaped steel of the track.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] like Figures 2 to 7 As shown, this embodiment of a track clamp is used to clamp and lock two mutually perpendicular C-shaped steels (such as the inclined beam and track of a photovoltaic system). No welding process is required. Only a mounting hole needs to be pre-drilled on the wing plate of one of the C-shaped steels (inclined beam). The installation is convenient and quick. This structure can be used to quickly build photovoltaic system guide rails, etc.

[0029] Taking the existing structure as an example, the C-shaped steel 30 includes a web 31 and flanges 32 that are perpendicular to both sides of the web 31. Each flange 32 has a relatively inwardly turned hook portion 33 at its outer end away from the web 31, and a C-shaped opening 35 is formed between the two hook portions 33.

[0030] like Figure 3The track block includes a block body 10 and a connector 20.

[0031] The pressing block body 10 includes a base plate 11 and two side plates 12. The two side plates 12 are erected above the front and rear edges of the base plate 11 at intervals, and an installation space 13 is formed between the two side plates 12.

[0032] The bottom surface of the middle part of the pressure block body 10 forms a slot 14 that extends upward and connects to the installation space 13. The slot 14 includes a bottom slot 111 located on the bottom plate 11 and a side slot 121 located on the side plate 12. The slot 14 is used to avoid and engage the end hook portion 33 of the wing plate 32 of the track C-shaped steel 301.

[0033] The left side of the slot 14 of the pressure block body 10 forms a locking part 15. The left and right widths of the locking part 15 match the depth of the track C-shaped steel 301. The left end of the locking part 15 can abut against the web plate 31 of the track C-shaped steel 301 to cooperate with the slot 14 to lock the wing plate 32 of the track C-shaped steel 301.

[0034] A locking part 16 is formed on the right side of the slot 14 of the pressure block body 10. The bottom plate 11 of the locking part 16 is provided with a vertically penetrating connecting hole 112. The connecting hole 112 can be connected to the pre-drilled mounting hole 34 on the wing plate 32 of the inclined beam C-shaped steel 302. The locking part 16 and the inclined beam C-shaped steel 302 are pressed and fixed by the connector 20 passing through the connecting hole 112 and the mounting hole 34.

[0035] Typically, the track C-shaped steel 301, with its front-to-back orientation and flange 32 facing downwards, overlaps the inclined beam C-shaped steel 302, which is positioned laterally and has its flange 32 facing upwards. To fix the two together, the left side locking portion 15 of the pressure block body 10 is first inserted into the C-shaped opening 35 of the track C-shaped steel 301, and the left end of the locking portion 15 abuts against the web 31 of the track C-shaped steel 301. The slot 14 in the middle of the pressure block body 10 provides space for the track C-shaped steel 302. The hook part 33 of 1 is inserted to avoid obstruction, and then the connecting hole 112 of the locking part 16 of the pressure block body 10 is aligned with the mounting hole 34 of the inclined beam C-shaped steel 302. Then, the connector 20 is passed through the connecting hole 112 and the mounting hole 34 to lock the locking part 16 of the pressure block body 10 and the inclined beam C-shaped steel 302. The clamping part of the pressure block body 10 can also press and fix the lower wing plate 32 of the track C-shaped steel 301 to the inclined beam C-shaped steel 302.

[0036] The pressure block body 10 of this embodiment has a simple and lightweight structure, making it easy to install. The snap-fit ​​part 15 can firmly clamp the track C-shaped steel 301. The left end of the snap-fit ​​part 15 can abut against the web plate 31 of the track C-shaped steel 301, providing support. The bottom plate 11 at the bottom of the snap-fit ​​part 15 can press against the wing plate 322 of the track C-shaped steel 301, resulting in a large contact area and higher structural stability. The slot 14 allows the track C-shaped steel 301 to move back and forth for adjustment. After the locking part 16 is locked with the inclined beam C-shaped steel 302, it can ensure the fixing effect of the snap-fit ​​part 15 on the track C-shaped steel 301. The connector 20 can adopt the common screw 21 and nut 22 structure, but it is not limited to this.

[0037] In this embodiment, the screw 21 of the connector 20 can pass through the connecting hole 112 and the mounting hole 34 from the mounting space 13, and then the nut 22 is locked inside the inclined beam C-shaped steel 302 at the other end of the screw 21. Both the screw 21 and the nut 22 can be hidden inside the mounting space 13 and the C-shaped steel 30, which can avoid external interference and improve the structural reliability.

[0038] The connector 20 may also include a flat washer 23 and a spring washer 24, which can improve the stability of the screw 21 and nut 22 after they are fastened, and prevent shock and loosening.

[0039] like Figures 5 to 7 In this embodiment, the side groove 121 of the slot 14 can be a wedge-shaped groove with a wider bottom, and an inclined abutment edge 122 is formed on the left side of the side groove 121. During installation, the bottom groove 111 allows the hook portion 33 of the track C-shaped steel 301 to pass through, while the abutment edge 122 in the side groove 121 can press against the hook portion 33 of the track C-shaped steel 301 to the right. By applying pressure, the pressure block body 10 can firmly press and clamp the track C-shaped steel 301.

[0040] In this embodiment, the bottom of the base plate 11 of the locking part 16 can also protrude to form a pressing rib 113. The pressing rib 113 is located on the right side of the connecting hole 112. Thus, when the connector 20 passes through the connecting hole 112 to lock the locking part 16 and the inclined beam C-shaped steel 302, the pressing rib 113 presses down against the wing plate 32 of the inclined beam C-shaped steel 302 to form a locking fulcrum, which can improve the locking and fixing effect. Moreover, the tighter the connector 20 locks the locking part 16 and the inclined beam C-shaped steel 302, the greater the pressing force of the snap-fit ​​part 15 on the track C-shaped steel 301, and the better the fixing effect.

[0041] In this embodiment, to improve the adaptability of the pressure block body 10, at least two slots 14 can be provided in the middle of the pressure block body 10. Each slot 14 is spaced apart from the left and right sides. A locking part 15 with different widths is formed between each slot 14 and the left end of the pressure block body 10, thereby allowing each locking part 15 to be matched with different types of rail C-shaped steel 301 (such as...). Figure 6 and Figure 7As shown), each slot 14 can accommodate the hook portion 33 of different track C-shaped steel 301.

[0042] Furthermore, in order to improve the ease of installation, the snap-fit ​​part 15 in this embodiment has a gradually narrowing bottom width while maintaining the top width to match the depth of the track C-shaped steel 301. This makes the left and right widths of the bottom 151 of the snap-fit ​​part slightly smaller than the distance between the inner web 31 and the hook part 33 of the track C-shaped steel 301, so as to facilitate the snap-fit ​​part 15 to be snapped in during installation.

[0043] In this embodiment, the top of the two side plates 12 of the locking part 16 can be set as a sloping side 123 with the left side higher than the right side, which can reduce the material and ensure the structural strength, while facilitating the locking and installation of the connector 20.
