Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket assembly technology, and in particular to a track fixing component. Background Technology

[0002] With the widespread application of photovoltaic power generation technology, the installation method of the track in photovoltaic brackets directly affects construction efficiency and structural stability. Currently, traditional track fasteners mostly adopt a structure of flat hooks and pressure blocks, requiring the track to be placed horizontally on the hooks for installation. However, this type of structure has significant drawbacks: First, the track installation direction is limited, and the angle cannot be adjusted according to actual needs; second, the position of the pressure block needs to be manually adjusted and locked step by step during installation, which is cumbersome and time-consuming; in addition, the pressure block is prone to local breakage due to excessive torque during the locking process, affecting the fixing effect and service life.

[0003] While existing technologies offer some improvements to address the aforementioned issues, such as adding track placement slots or optimizing the shape of the clamping blocks, they still fail to completely resolve problems like poor adaptability for multi-angle installation, complex installation procedures, and easy damage to the clamping blocks. Therefore, there is an urgent need for a track fixing component that can achieve rapid multi-directional track positioning and installation, simplify the operation process, and enhance structural stability. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the technical problem to be solved by this utility model is to propose a track fixing component, which adopts the following technical solution:

[0005] A track fixing assembly, comprising

[0006] A base for supporting the track, the base having a pre-installed groove for fixing one side of the track;

[0007] A pressure block is rotatably connected to the base, and the pressure block is provided with a pressing part for pressing the other side of the track.

[0008] The bottom of the pre-installation slot is provided with a clearance groove, which is inclined along the direction of the track extension.

[0009] It also includes fasteners and springs, the fasteners passing through the base and the pressure block for locking the pressure block and the base to fix the track, and the springs for opening the base and the pressure block at a certain angle in the unlocked state.

[0010] As a further improvement, the top of the track is provided with a slide rail, and the bottom sides are respectively provided with a first base plate and a second base plate. The first base plate extends into the pre-installation groove along the relief groove. When the fastener is locked, the holding part presses against the second base plate, and the upper surface of the first base plate abuts against the lower surface of the pre-installation groove.

[0011] As a further improvement, the base is provided with a placement groove for supporting the track. One side of the placement groove is the pre-installation groove, and the other side is provided with a limiting boss for abutting against the outer side of the second base plate. The limiting boss is provided with a ramp structure on the side near the second base plate.

[0012] As a further improvement, the pressure block is provided with an elongated hole, the base is provided with a through hole, the fastener passes through the elongated hole and the through hole, the spring is sleeved on the fastener, with one end abutting against the pressure block and the other end abutting against the base.

[0013] As a further improvement, the base is provided with at least one anti-breakage protrusion near the through hole. When the fastener is tightened, the anti-breakage protrusion abuts against the pressure block or maintains a slight gap.

[0014] As a further improvement, the aforementioned pressing part is provided with a protrusion, and the aforementioned second base plate is provided with a recess that matches the aforementioned protrusion.

[0015] As a further improvement, the base is provided with a shaft hole, and one end of the pressure block is provided with a shaft pin. The shaft hole and the shaft pin cooperate to form a rotatable connection.

[0016] As a further improvement, the opening angle between the aforementioned pressure block and the aforementioned base ranges from 10° to 60°.

[0017] Further improvements include a hook assembly, which includes a first connecting plate and a second connecting plate bolted to the first connecting plate, with the base fixed to the first connecting plate and the second connecting plate fixed to the roof hook.

[0018] As a further improvement, the fasteners are bolts and nuts, and the bolts are sequentially passed through the pressure block, the base and the first connecting plate, and then locked by the nuts.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Firstly, this utility model is equipped with a pressure block that can rotate around the base and an automatic opening structure that works with a spring and fasteners. The elastic force of the spring causes the pressure block to automatically open to a certain angle in the unlocked state, so that there is no need to manually adjust the angle of the pressure block during operation. The track can be directly inserted at an angle from the base and the opening of the pressure block, which significantly improves the installation efficiency and is especially suitable for complex installation environments.

[0021] Secondly, this utility model features an inclined clearance groove and a limiting boss on the base, combined with the combination structure of the pressing block and the concave and convex parts of the track base plate, achieving precise positioning for multi-angle installation. After the track slides obliquely into the pre-installation groove through the clearance groove, the limiting boss and the pressing block together restrict the track displacement, ensuring that the track can be quickly positioned and fixed at different installation angles, thus broadening the adaptability of the track's installation direction on the roof hook.

[0022] Thirdly, this utility model features an anti-breakage protrusion near the fastener hole on the base, and maintains a small gap at the corresponding position of the pressure block to prevent breakage caused by over-tightening of the pressure block. Specifically, when the fastener tightening torque is too large, the anti-breakage protrusion contacts the pressure block to disperse stress, preventing the pressure block from breaking due to localized stress concentration, thus improving the reliability and service life of the overall structure.

[0035] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

The terms "part," "side," "end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0037] like Figure 1 and Figure 2 As shown, a track 100 fixing assembly includes a base 1 and a pressure block 2. The top of the base 1 is provided with a placement groove 12 for supporting the track 100, and one side of the placement groove 12 is a pre-installation groove 11 for fixing one side of the track 100. The pressure block 2 is rotatably connected to the base 1, and the pressure block 2 is provided with a pressing part 21 for pressing the other side of the track 100.

[0038] In one specific embodiment, the base 1 is provided with a shaft hole 16, and one end of the pressure block 2 is provided with a shaft pin 23. The shaft hole 16 and the shaft pin 23 cooperate to form a rotatable connection.

[0039] like Figure 2 As shown, the bottom of the pre-installation slot 11 is provided with a clearance slot 11a, which is inclined along the extension direction of the track 100. The pre-installation slot 11 and the clearance slot 11a are used to accommodate one side of the track 100 and pre-fix it, thereby expanding the insertion space of the track 100, making it easier to insert the track 100 and improving installation efficiency.

[0040] like Figure 3 and Figure 4 As shown, a slide rail 101 is provided on the top of the track 100 for installing photovoltaic panels or photovoltaic panel connection components. A first base plate 102 and a second base plate 103 are respectively provided on the bottom two sides of the track 100. The first base plate 102 extends into the pre-installation groove 11 along the aforementioned relief groove 11a. When the fastener 3 is tightened, the pressing part 21 of the pressure block 2 presses the second base plate 103, and the upper end surface of the first base plate 102 abuts against the lower end surface of the pre-installation groove 11.

[0041] It should be noted that the first base plate 102 and the second base plate 103 in the above embodiments can be metal plates fixed by bolts, welding or other means, or they can be integrally formed with the track 100, or have V-groove track 100, H-shaped track 100 or other features that can be clamped.

[0042] Furthermore, such as Figure 2 As shown, it also includes a fastener 3 and a spring 4. The fastener 3 passes through the base 1 and the pressure block 2 and is used to lock the pressure block 2 and the base 1 to fix the track 100. The spring 4 is used to open the base 1 and the pressure block 2 at a certain angle in the unlocked state to provide sufficient space for the track 100 to be inserted. The opening angle of the pressure block 2 and the base 1 is in the range of 10° to 60°. Preferably, the opening angle of the pressure block 2 and the base 1 is 30°.

[0043] like Figures 2-4 As shown, one side of the placement groove 12 is the aforementioned pre-installed groove 11, and the other side is provided with a limiting boss 13 for abutting against the outer side of the second base plate 103. The limiting boss 13 has a ramp structure on the side closest to the second base plate 103. The limiting boss 13 and the pressing part 21 together restrict the displacement of the track 100. Specifically, as shown... Figures 3-4 As shown, after the track 100 slides obliquely into the pre-installation groove 11 through the clearance groove 11a, the second base plate 103 moves down along the slope structure as the fastener 3 is tightened, ensuring that the track 100 can be quickly positioned and fixed at different installation angles, thus broadening the adaptability of the track 100 to the installation direction on the roof hook 300.

[0044] like Figure 2 As shown, the pressure block 2 has an elongated hole 22, and the base 1 has a through hole 14. The fastener 3 passes through the elongated hole 22 and the through hole 14. The spring 4 is sleeved on the fastener 3, with one end abutting against the pressure block 2 and the other end abutting against the base 1. The purpose of the elongated hole 22 on the pressure block 2 is to ensure that the fastener 3 remains perpendicular to the base 1 when the pressure block 2 and the base 1 are opened at a certain angle, facilitating the locking of the fastener 3 during fixing. The spring 4 is used to push the base 1 and the pressure block 2 to automatically open at a certain angle in the unlocked state, facilitating the insertion and adjustment of the track 100.

[0045] Specifically, the aforementioned through hole 14 can also be a threaded hole. Correspondingly, the fastener 3 is a bolt, which locks the pressure block 2 to the base 1.

[0046] like Figure 2As shown, at least one anti-breakage boss 15 is provided on the base 1 near the through hole 14. When the fastener 3 is locked, the anti-breakage boss 15 abuts against the pressure block 2 or maintains a slight gap. When the fastener 3 is locked, if the applied torque is too large, the inner surface of the pressure block 2 will contact the anti-breakage boss 15, forming a rigid support and preventing the pressure block 2 from breaking due to local stress concentration. In a preferred embodiment, the initial gap between the anti-breakage boss 15 and the pressure block 2 is designed to be 0.5-1mm, which allows for a certain amount of elastic deformation while limiting over-tightening.

[0047] like Figure 2 As shown, the holding part 21 is provided with a protrusion 21a, and the second base plate 103 is provided with a recess 103a that matches the protrusion 21a. When the fastener 3 is locked, the protrusion 21a of the holding part 21 engages into the recess 103a of the second base plate 103, which can prevent the track 100 from shifting under force and increase the overall stability.

[0048] like Figure 1 As shown, it also includes a hook assembly, which includes a first connecting plate 201 and a second connecting plate 202 bolted to the first connecting plate 201. The base 1 is fixed to the first connecting plate 201, and the second connecting plate 202 is fixed to the roof hook 300. In one specific embodiment, both the first connecting plate 201 and the second connecting plate 202 are L-shaped. The connecting portion of the first connecting plate 201 and the second connecting plate 202 is provided with an elongated opening for adjusting the height distance between the roof hook 300 and the track 100 fixing assembly. In one specific embodiment, the fastener 3 is a bolt and a nut. The bolt passes through the pressure block 2, the base 1, and the first connecting plate 201 in sequence, and is then locked from the lower end of the first connecting plate 201 by the nut.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
