Description

Technical Field

[0001] The utility model relates to the technical field of corner codes, in particular to an adjustable corner code for connecting photovoltaic frames. Background Technique

[0002] When assembling photovoltaic modules, photovoltaic frames are required to wrap and protect the photovoltaic modules, and when the photovoltaic frames wrap the photovoltaic modules, corner codes are needed to connect the photovoltaic frames. For example, the patent with the application number: CN202023163292.0 discloses a corner code with an introduction ramp. The corner code includes: two plug-in terminals arranged in an L shape. The plug-in terminal includes: a corner code head and a locking body, and an introduction ramp is arranged on the side of the locking body. The structure of the utility model is simple, and an introduction ramp is arranged on the side of the locking body, so that the corner code can be quickly inserted into the hole of the to-be-connected frame. However, when the existing corner codes such as the above are in use, their structures are relatively fixed. Since photovoltaic modules are divided into single-glass modules and double-glass modules, and there are differences in the sizes of the two types of modules, the corner codes such as the above cannot meet the connection requirements of the frames of multiple modules. Therefore, the utility model improves a corner code that can adapt to connect the frames of single-glass and double-glass modules. Summary of the Invention

[0003] The embodiment of the present disclosure relates to an adjustable corner code for connecting photovoltaic frames. By adjusting the setting of the ejector pin, it can solve the problem of the narrow application range of the existing corner codes. And because the stress groove is composed of an irregular shape, not only the weight of this connecting corner code is reduced, the cost is reduced, but also the occurrence of stress concentration is reduced, and the service life of this connecting corner code is prolonged.

[0004] In the first aspect of the present disclosure, an adjustable corner code for connecting photovoltaic frames is provided, specifically including: a corner code connecting body, the corner code connecting body is in an L-shaped structure; a stress groove is opened at the bending part of the corner code connecting body; the stress groove is in an irregular shape; two adjusting support cylinders are fixedly installed inside the corner code connecting body; a positioning bolt rod is installed in the adjusting support cylinder by threads; a torsion wheel is fixed at one end of the positioning bolt rod; an adjusting ejector pin is arranged at the inner position of the corner code connecting body; a positioning chuck is arranged on the inner side of the corner code connecting body.

[0005] In at least some embodiments,

[0006] The outer side of the positioning chuck is in an inclined structure; a fixing and shaping groove is opened inside the positioning chuck; the fixing and shaping groove is in an annular structure; a fixing and shaping part is also slidably installed inside the corner code connecting body; the fixing and shaping part is located inside the positioning chuck; the fixing and shaping part is a cylindrical structure with openings on both sides.

[0007] In at least some embodiments,

[0008] A tension spring is jointly installed between the inside of the fixing and shaping member and the inside of the corner code connecting body; a restricted positioning rod is fixedly installed at the central position on the inner side of the fixing and shaping member; the restricted positioning rod is of a cylindrical structure; a limiting jack is opened on the circumferential outer wall of the restricted positioning rod; the other end of the positioning bolt rod is inserted into the inside of the limiting jack.

[0009] In at least some embodiments,

[0010] After the positioning bolt rod is rotated, one end of the positioning bolt rod will slide out from the inside of the limiting jack; after one end of the positioning bolt rod slides out from the inside of the limiting jack, the restricted positioning rod and the fixing and shaping member will move outward under the action of the tension spring; after the fixing and shaping member moves outward to a certain position, the fixing and shaping member will be inserted into the inside of the fixing and shaping groove.

[0011] The utility model provides an adjustable photovoltaic frame connecting corner code, which has the following beneficial effects:

[0012] (1) An adjusting thimble is arranged in the utility model. During the preparation of the connecting corner code by using a mold, the thimble on the thimble plate in the mold can be directly used to push the adjusting thimble during demolding according to the use requirements, so that the length of the adjusting thimble can be adapted to the width of the frame assembly used in a matching manner. In this way, the connecting corner code can be adjusted in size according to the style of the connected component, and the application range of the connecting corner code is improved.

[0013] (2) A fixing and shaping member is arranged in the utility model. After the positioning chuck is inserted into the insertion hole inside the frame, the fixing and shaping member is inserted into the inside of the fixing and shaping groove. By inserting the fixing and shaping member, the strength of the positioning chuck is enhanced, and it is avoided that the positioning chuck made of elastic material is deformed over time, resulting in that the positioning chuck cannot be firmly inserted into the insertion hole in the frame. In this way, the service life and the use stability of the connecting corner code can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0026] Please refer to Figures 1 to 6 :

[0027] Embodiment 1:

[0028] The present utility model provides an adjustable photovoltaic frame connection corner code, including: a corner code connector 1, the corner code connector 1 is an L-shaped structure; a stress groove 2 is provided at the bending part of the corner code connector 1; the stress groove 2 is of an irregular shape; two adjusting support cylinders 3 are fixedly installed inside the corner code connector 1; a positioning bolt rod 4 is threadedly installed inside the adjusting support cylinder 3; a torsion wheel is fixed at one end of the positioning bolt rod 4; an adjusting thimble 6 is arranged at the inner position of the corner code connector 1; a positioning chuck 5 is arranged inside the corner code connector 1.

[0029] The corner code connector 1, the positioning chuck 5 and the adjusting thimble 6 are made of a composite limit-enhanced thermoplastic resin, so the corner code connector 1, the positioning chuck 5 and the adjusting thimble 6 have certain strength and toughness;

[0030] The manufacturing process of the stress groove 2 is as follows: First, two irregular figures symmetrically distributed are set at the side cross-section of the angle code connector 1, and then obtained through the thermoforming process;

[0031] After the stress groove 2 is opened, the overall quality of this connecting angle code can be significantly reduced. And since the cross-section of the stress groove 2 is composed of multiple irregular curves, and the connection between the curves is transitioned through smooth curves, the situation of local stress concentration can be avoided, and to a certain extent, the service life of the angle code is increased.

[0032] Example 2, on the basis of Example 1,

[0033] The outer side of the positioning chuck 5 is of an inclined structure; a fixing and shaping groove 7 is opened inside the positioning chuck 5; the fixing and shaping groove 7 is of an annular structure; a fixing and shaping part 8 is also slidably installed inside the angle code connector 1; the fixing and shaping part 8 is located inside the positioning chuck 5; the fixing and shaping part 8 is of a cylindrical structure with openings on both sides; a tension spring 9 is jointly embedded between the inside of the fixing and shaping part 8 and the inside of the angle code connector 1; a limited positioning rod 10 is fixedly installed at the center position on the inner side of the fixing and shaping part 8.

[0034] After connecting the angle code connector 1 with the photovoltaic frame, the positioning chuck 5 will be stuck into the insertion hole of the photovoltaic frame. At this time, by rotating the positioning bolt rod 4, one end of the positioning bolt rod 4 slides out from the inside of the limit insertion hole 11, canceling the limit of the positioning bolt rod 4 on the limited positioning rod 10, so that the limited positioning rod 10 and the fixing and shaping part 8 move outward under the action of the tension spring 9, and the fixing and shaping part 8 is inserted into the inside of the fixing and shaping groove 7 by moving outward, and the fixing and shaping part 8 is inserted into the inside of the positioning chuck 5, using the fixing and shaping part 8 to improve the strength of the positioning chuck 5, so that the positioning chuck 5 will not change its shape with the increase of the use time, preventing the insertion hole of the positioning chuck 5 and the photovoltaic frame from being mismatched due to deformation, resulting in the disconnection of the angle code and the photovoltaic frame.

[0035] Example 3, on the basis of Example 2,

[0036] The limited positioning rod 1 is of a cylindrical structure; a limit insertion hole 11 is opened on the circumferential outer wall of the limited positioning rod 10; the other end of the positioning bolt rod 4 is inserted into the inside of the limit insertion hole 11; after the positioning bolt rod 4 is rotated, one end of the positioning bolt rod 4 will slide out from the inside of the limit insertion hole 11; after one end of the positioning bolt rod 4 slides out from the inside of the limit insertion hole 11, the limited positioning rod 10 and the fixing and shaping part 8 will move outward under the action of the tension spring 9; after the fixing and shaping part 8 moves outward to a certain position, the fixing and shaping part 8 will be inserted into the inside of the fixing and shaping groove 7.

[0037] During the preparation of this connecting angle code, when adjusting the ejector pin 6, it is necessary to move the corresponding appropriate distance according to the position size of the single-glass component slot. The single-glass component adopts Figure 1 of the state, and the double-glass component adopts Figure 2 of the state. The appropriate distance can be obtained by the following rules: Now assume that the hole width of the single-glass component is A, the hole width of the double-glass component is B, and the value of A is greater than B. That is, the hole width difference between the double-glass component and the single-glass component at this time is "A - B". Therefore, the appropriate distance for the movement of the ejector pin 6 should be "A - B".

[0038] The working principle of this embodiment:

[0039] During use, first, utilize the toughness of the angle code connector 1 and the positioning chuck 5 itself to respectively snap the two positioning chucks 5 into the insertion holes on two photovoltaic frames. Then, by rotating the positioning bolt rod 4, one end of the positioning bolt rod 4 slides out from the inside of the limit jack 11, canceling the limit of the positioning bolt rod 4 on the restricted positioning rod 10. The restricted positioning rod 10 and the fixing and shaping part 8 move outward under the action of the tension spring 9, and the fixing and shaping part 8 is inserted into the inside of the fixing and shaping groove 7 through outward movement. The fixing and shaping part 8 is inserted into the inside of the positioning chuck 5, and the strength of the positioning chuck 5 is improved by using the fixing and shaping part 8, so that the shape of the positioning chuck 5 will not change with the increase of the use time, preventing the insertion hole of the positioning chuck 5 and the photovoltaic frame from being mismatched due to deformation, resulting in the separation of the angle code and the photovoltaic frame.
