Description

Technical Field

[0001] The utility model relates to a photovoltaic guide rail quick installation fixture. Background Art

[0002] When laying photovoltaic panels on the roof, it is necessary to first lay corresponding photovoltaic rails on the roof for installing the photovoltaic panels. The photovoltaic rails are installed on the roof through structures such as hooks and brackets. The installation structure is usually provided with clamps for locking the photovoltaic rails.

[0003] The Chinese patent CN30220964706U previously applied by our company discloses a base support structure for a photovoltaic module guide rail, which includes a clamp assembly, the clamp assembly includes a base composed of a table panel for supporting the guide rail and a base formed on the lower edge of the table panel, a locking nut that is screwed together with the screw column to fix the base on the screw column, a wedge pressure plate for pressing the guide rail to the upper edge of the table panel, and a locking screw that connects the wedge pressure plate and the table panel in series to actuate the wedge pressure plate to press the guide rail onto the table panel, one end of the wedge pressure plate is an engaging portion that is inserted into the groove on the other side of the guide rail, and the other end is engaged with the wedge-shaped wall of the wedge block so that the engaging portion of the wedge pressure plate has a tendency to slide obliquely into or out of the groove on the side of the guide rail.

[0004] When the above-mentioned clamp assembly is in use, the wedge pressure block and the table panel are fitted against the wall, so that the wedge pressure plate slides obliquely into the side groove of the guide rail to lock the guide rail. During the process of tightening the locking screw, the wedge pressure block will move horizontally left and right relative to the table panel in a direction perpendicular to the length of the guide rail, which is not conducive to the installer's quick locking installation of the guide rail, thereby reducing the installation efficiency of the guide rail. Utility Model Content

[0005] The utility model provides a photovoltaic guide rail quick installation fixture, which can effectively solve the above problems.

[0006] The utility model is achieved in this way:

[0007] A photovoltaic rail quick installation fixture comprises a base, a top bearing seat, a swing pressure block and a tension bolt which can be put on the mounting plate of the mounting structure, wherein the tension bolt passes through the through hole on the swing pressure block, the plug hole on the base and the air-avoiding hole on the mounting plate in sequence, and is screwed with the tension threaded hole on the top bearing seat to attach the installation fixture to the mounting plate;

[0008] The base is provided with a supporting groove for accommodating and installing the guide rail and a matching groove arranged at one end away from the supporting groove, and the supporting groove has a hook portion that is engaged with the hook of the groove on the guide rail at one end away from the matching groove; one end of the swing pressure block is bent to form a rotating column that is engaged with the matching groove, and the other end is protruded to form an anchor portion that is engaged with the hook of another groove on the guide rail, and the top seat is vertically fixed with sealing plates that contact and press the two sides opposite to the rotating column in parallel to the length direction of the guide rail to limit the rotating column from sliding horizontally out of the matching groove;

[0009] The tightening bolt is connected in series with the swing pressure block, the base, and the mounting plate and is screwed into the threaded hole of the bearing top seat, which can cause the swing pressure block to swing, so that its anchor part and the hook of the slot on the guide rail are engaged, and at the same time, the other slot of the guide rail is pressed against the hook part to lock the guide rail in the supporting slot.

[0010] As a further improvement, the matching groove is parallel to the length direction of the guide rail and passes through the base on both sides. The inner wall of the matching groove is an arc groove for the rotating column to slide into and rotate with the rotating column, and the groove opening is an expanded shape to avoid space and make way for the bending part between the swing pressure block and the rotating column.

[0011] As a further improvement, the width of the slot opening of the matching slot is smaller than the diameter of the slot wall inside the matching slot, so as to limit the longitudinal separation of the rotating column from the matching slot.

[0012] As a further improvement, the notch of the matching groove is composed of an arc portion on the left and a clearance portion on the right, and the clearance portion is gradually reduced from bottom to top; within the swing stroke of the swing pressure block, the arc portion makes way for the bending portion.

[0013] As a further improvement, a reinforcement hole located below the supporting groove is opened on the base parallel to the length direction of the guide rail.

[0014] As a further improvement, the groove wall on one side relative to the hook portion is a ramp with a wedge pressure surface, and a protrusion at one end of the swing pressure block relative to the rotating portion forms an inclined block perpendicular to the anchor portion, and the side of the inclined block away from the anchor portion is a guide surface that slides in contact with the wedge pressure surface; when the swing pressure block is actuated by the tightening bolt and swings to the anchor portion and engages with the hook in the slot on the guide rail, the wedge pressure surface of the inclined block fits with the guide surface of the ramp, and continuing to tighten the tightening bolt can actuate the inclined block to slide down along the guide surface to fill the gap between the guide rail and the ramp.

[0015] As a further improvement, the through hole on the swing pressure block is a waist-shaped hole that makes way for the tensioning bolt, and the surface of the swing pressure block for the nut end of the tensioning bolt to contact and press is an arc surface.

[0016] As a further improvement, a buffer spring is sleeved on the screw end of the tension bolt, one force-bearing end of the buffer spring contacts the edge of the through hole on the swing pressure block, and the other force-bearing end contacts the edge of the socket on the base.

[0017] The beneficial effects of the utility model are:

[0018] The method of locking and fixing the guide rail in the present application is to activate the swing pressure block to rotate by tightening the bolt until the anchor portion on it engages with the tooth hook on the other side of the guide rail to lock the guide rail in the supporting groove. Since the matching groove of the swing pressure block and the base are assembled together by means of rotational cooperation, when in use, the swing pressure block will not move horizontally to the left and right perpendicular to the length direction of the guide rail. The present application has the advantages of simple structure and easy installation, and can greatly improve the installation efficiency of the guide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] A photovoltaic rail 110 quick installation fixture, which can be adaptively installed on any installation structure (such as a bracket such as Figure 7 As shown, the hook is as Figure 8 On a mounting plate 100 having a structure such as shown in the figure.

[0031] like Figure 1 to Figure 6 As shown, the mounting fixture includes a base 10, a top seat 20, a swing pressure block 30 and a tensioning bolt 40 that can be removed and placed on the mounting plate 100 of the mounting structure. The tensioning bolt 40 passes through the through hole 31 on the swing pressure block 30, the plug hole 11 on the base 10, and the air avoidance hole 101 on the mounting plate 100 in sequence, and is threadedly matched with the tensioning threaded hole 21 on the top seat 20 to attach the mounting fixture 120 to the mounting plate 100; the base 10 is provided with a supporting groove 12 for accommodating and installing the guide rail 110 and a matching groove 13 arranged at one end away from the supporting groove 12, and the supporting groove 12 has a side away from the matching groove 13. The hook portion 121 is hooked and engaged with the slot 111 on the guide rail 110, and one end of the swing pressure block 30 is bent to form a rotating column 32 that is rotatably engaged with the matching slot 13, and the other end is protruded to form an anchor portion 33 that is hooked and engaged with another slot 111 on the guide rail 110; the tightening bolt 40 is connected in series with the swing pressure block 30, the base 10, and the mounting plate 100 and is screwed into the threaded hole 21 of the bearing top seat 20, which can cause the swing pressure block 30 to swing, so that the anchor portion 33 is hooked and engaged with the slot 111 on the guide rail 110, and at the same time, the other slot 111 of the guide rail 110 is pressed against the hook portion 121, so that the guide rail 110 is locked and installed in the supporting slot 12.

[0032] The structures of the various components of the utility model are described below.

[0033] like Figure 1 to Figure 4 As shown, the matching groove 13 is parallel to the length direction of the guide rail 110, and passes through the base 10 on both sides. The inner groove wall of the matching groove 13 is an arc groove for the rotating column 32 to slide into and rotate with the rotating column 32, and the groove opening is an expanded opening for the bending portion 35 between the swing pressure block 30 and the rotating column 32 to avoid space and make way; the groove opening width of the matching groove 13 is smaller than the diameter of the inner groove wall of the matching groove 13 to limit the longitudinal separation of the rotating column 32 from the matching groove 13, and the top seat 20 is vertically fixed on the two sides opposite to the length direction of the guide rail 110, and the sealing plates 22 are pressed against the two sides opposite to the rotating column 32 to limit the rotating column 32 from sliding horizontally out of the matching groove 13.

[0034] It is worth noting that after the clamp 120 locks the guide rail 110 on the mounting structure, when the guide rail 110 is subjected to longitudinal external force, since the slot width of the mating slot 13 is smaller than the diameter of the inner slot wall of the mating slot 13, it can also limit the longitudinal separation of the rotating column 32 from the mating slot 13, thereby making it possible to lock the guide rail 110 using the clamp 120 of the present application, thereby having higher safety and installation stability.

[0035] like Figure 1 to Figure 3 As shown, the notch of the matching groove 13 is composed of an arc portion 131 on the left and a clearance portion 132 on the right, and the clearance portion 132 is gradually reduced from bottom to top. Such a design can increase the rotatable angle range of the swing pressure block 30, making it more convenient to place the guide rail 110 in the supporting groove 12; within the swing stroke of the swing pressure block 30, the arc portion 131 makes way for the bending portion 35; it should be noted here that when the tightening bolt 40 is tightened, there is a safety gap between the arc portion 131 and the bending portion 35 to avoid interference between the swing pressure block 30 and the arc portion 131.

[0036] like Figure 3 to Figure 6 As shown, a reinforcement hole 14 is provided on the base 10 parallel to the length direction of the guide rail 110 and located below the supporting groove 12. The provision of the reinforcement hole 14 can improve the overall structural strength of the base 10; the groove wall on one side relative to the hook portion 121 is an inclined platform 122 with a wedge pressure surface 1221, and the swing pressure block 30 is formed with an inclined block 34 perpendicular to the anchor portion 33 on one end of the convex portion relative to the rotating portion, and the inclined block 34 is away from the anchor portion 33 on one side. In order to fit the guide surface 341 that slides with the wedge pressure surface 1221, when the swing pressure block 30 is actuated by the tightening bolt 40 and swings to the point where the anchor portion 33 hooks and engages with the slot 111 on the guide rail 110, the wedge pressure surface 1221 of the oblique insertion block 34 fits with the guide surface 341 of the ramp 122. Continuing to tighten the tightening bolt 40 can actuate the oblique insertion block 34 to slide downward along the guide surface 341 to fill the gap between the guide rail 110 and the ramp 122.

[0037] like Figure 1 to Figure 3 As shown, the through hole 31 on the swing pressure block 30 is a waist-shaped hole that makes way for the tensioning bolt 40, and the surface of the swing pressure block 30 for the nut end of the tensioning bolt 40 to contact and press is an arc surface 301; compared with designing the surface as a plane, in such a design, during the process of tightening the tensioning bolt 40, the nut end of the tensioning bolt 40 can always remain tangent to the arc surface 301, while avoiding interference between the nut end and the swing pressure block 30, it is also possible to stably apply force to the swing pressure block 30 and actuate the swing pressure block 30 to swing.

[0038] like Figure 1 to Figure 3As shown, a buffer spring 50 is provided on the screw end sleeve of the tightening bolt 40, one force-bearing end of the buffer spring 50 contacts the edge of the through hole 31 on the swing pressure block 30, and the other force-bearing end contacts the edge of the socket 11 on the base 10. Through the design of the buffer spring 50, the movement process of the swing pressure block 30 can be made smoother and a buffering effect can be played.

[0039] Combination Figure 1 to Figure 3 , the assembly of the utility model is described below.

[0040] Place the base 10 on the mounting plate 100, align the rotating column 32 on the swing pressure block 30 and slide it into the matching groove 13 on the base 10, place the top seat 20 under the mounting plate 100, so that the sealing plates 22 on both sides touch and press the two ends of the rotating column 32, and at this time, the sealing plates 22 and the two ends of the base 10 and the mounting plate 100 also form contact and pressure, and then pass the tightening bolt 40 through the through hole 31 on the swing pressure block 30, the socket 11 on the base 10, and the air avoidance hole 101 on the mounting plate 100 in sequence, and screw it with the tightening threaded hole 21 on the top seat 20 to complete the assembly of the clamp 120 on the mounting structure.

[0041] A method for installing a photovoltaic rail quick installation fixture is as follows:

[0042] S1: placing the guide rail 110 in the supporting groove 12 on the base 10 so that the hook portion 121 on the supporting groove 12 forms a hook engagement with the hook portion 121 on one side of the guide rail 110;

[0043] S2: Tightening the tension bolt 40 to actuate the swing pressure block 30 to swing until the anchor portion 33 thereon forms a hook engagement with the clamping groove 111 on the other side of the guide rail 110;

[0044] S3: Continue to tighten the tensioning bolt 40 to drive the actuating inclined insert block 34 to slide downward along the guide surface 341 to fill the gap between the guide rail 110 and the ramp 122, so that the other slot 111 of the guide rail 110 is pressed against the hook portion 121 to quickly lock the guide rail 110 in the supporting slot 12.

[0045] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
