Description

Technical Field

[0001] The utility model relates to the technical field of rivet corner brackets, and particularly relates to an integrated corner bracket member. Background Art

[0002] When rivets and corner brackets are used in combination, they are mainly used to fix and strengthen structural members, and are widely used in fields such as metal processing, building installation, and furniture manufacturing. The selection of corner brackets should be determined according to actual requirements and the thickness of the aluminum plate (or other materials). Generally speaking, the length and width of the corner bracket should be larger than the thickness of the material to be fixed, so as to better bear the load and disperse the stress. The selection of rivets needs to consider the thickness of the material to be fixed, the required bearing capacity, and the riveting method. The thicker the aluminum plate and the greater the load, the thicker the required rivets.

[0003] The existing rivets and corner brackets can be respectively referred to Figure 1 and Figure 2 As shown, the corner bracket 1 and the rivet 2 are separate parts. Not only do they need to be purchased separately, but they also need to be used in combination during use. Specifically, an electric drill is used to drill corresponding through holes 3 in the corner bracket 1 and the material to be fixed. Note that the position of the hole should be accurate to avoid drilling off or drilling through the material. Align the corner bracket 1 with the position to be fixed and hold the corner bracket 1 by hand to ensure that it fits tightly with the material to be fixed. Then, place the rivet 2 into the drilled through hole 3, ensure that the rivet 2 is aligned with the through hole 3 and the head of the rivet 2 protrudes from the corner bracket 1 by a certain length. Finally, use a riveting tool to stretch the tail of the rivet 2 to a certain length to form a firm connection with the material to be fixed. Since the rivet 2 and the corner bracket 1 are arranged separately, before riveting, it is necessary to manually hold the rivet 2 in the through hole 3 of the corner bracket 1 and then use a riveting tool for riveting. The whole process is time-consuming and laborious, increasing the working intensity. Summary of the Utility Model

[0004] The utility model provides an integrated corner bracket member to solve the technical problem that the separate arrangement of rivets and corner brackets in the prior art leads to a time-consuming and laborious riveting process and a large working intensity.

[0005] To solve the above problems, the integrated corner bracket member provided by the utility model adopts the following technical solutions:

[0006] An integrated corner bracket member includes a corner bracket and a rivet. The corner bracket has a through hole for the rivet to be inserted. The outer periphery of the rivet has a connecting structure for fixing the rivet in the through hole to form an integrated structure with the corner bracket.

[0007] The beneficial effects of the integrated angle code provided by the present utility model are as follows: The angle code and the rivet are pre-connected through a connection structure to form an integrated structure. When riveting with other devices, it is no longer necessary for designers to manually hold the rivet to ensure that the rivet is stably in the perforation of the angle code, which improves the usage efficiency during the construction of the angle code and the rivet, reduces the working intensity, and also ensures the accuracy of riveting, effectively solving the technical problem in the prior art that the rivet and the angle code are separately arranged, resulting in time-consuming and laborious riveting process and high working intensity.

[0008] Further, the connection structure is a detachable structure, so that the rivet and the angle code form a detachable integrated structure.

[0009] Further, the connection structure is a protrusion located on the outer periphery of the rivet, and the protrusion is used to make the rivet be press-fitted in the perforation. The protrusion structure is relatively simple, which is convenient for press-fitting. Press-fitting has the advantages of simple structure and firm connection, and can be easily disassembled by setting a small interference amount.

[0010] Further, the rivet includes a rivet head and a rivet rod, and the protrusion is located on the outer periphery of the rivet rod, and one side of the protrusion is connected to the rivet head. This can avoid the problem of waste caused by the unused gap when there is a gap between the protrusion and the rivet head.

[0011] Further, the protrusion is an annular protrusion, and its dimension along the length direction of the rivet rod is one-third of the length of the rivet rod.

[0012] Further, the protrusions are multiple strip-shaped protrusions, and the multiple strip-shaped protrusions are evenly distributed at intervals in the circumferential direction of the rivet rod, and the dimension of each strip-shaped protrusion along the length direction of the rivet rod is one-third of the length of the rivet rod.

[0013] Further, the angle code is an L-shaped plate, and a perforation is provided on one side plate of the L-shaped plate, and a mounting hole for connecting with other devices is provided on the other side plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] It should be noted that the main concept of the present utility model is to pre-connect the angle bracket 1 and the rivet 2 arranged separately in the prior art through a connection structure to form an integrated structure. When riveting with other devices, it is no longer necessary for designers to manually hold the rivet 2 to ensure that the rivet 2 is stably located in the perforation 3 of the angle bracket 1, which improves the use efficiency of the angle bracket 1 and the rivet 2 during construction, reduces the working intensity, and also ensures the accuracy of riveting, so as to solve the technical problem that the rivet 2 and the angle bracket 1 are arranged separately in the prior art, resulting in time-consuming and laborious riveting process and high working intensity.

[0029] After introducing the basic principle of the present utility model, the various non-limiting embodiments of the present utility model will be specifically introduced below. The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0030] Next, with reference to several representative embodiments of the present utility model, the principle and spirit of the present utility model will be elaborated in detail.

[0031] Embodiment 1 of the integrated angle bracket provided by the present utility model:

[0032] As Figures 1 to 4 shown, an integrated angle bracket includes an angle bracket 1 and a rivet 2. The angle bracket 1 has a perforation 3 for the rivet 2 to insert. On this basis, the outer periphery of the rivet 2 has a connection structure for fixing the rivet 2 in the perforation 3 to form an integrated structure with the angle bracket 1.

[0033] Specifically, the angle bracket 1 is an L-shaped plate. A perforation 3 is provided on one side plate of the L-shaped plate, and a mounting hole 4 for connecting with other devices is provided on the other side plate.

[0034] The design requirement of the connection structure is to achieve the integrated connection of the angle bracket 1 and the rivet 2 while having a relatively simple structure and not increasing the structural complexity of the rivet 2 or the angle bracket 1, so as to facilitate the quick pre-assembly of the angle bracket 1 and the rivet 2. In this embodiment, the connection structure is a detachable structure, so that the rivet 2 and the angle bracket 1 form a detachable integrated structure.

[0035] Specifically, the connection structure is a protrusion located on the outer periphery of the rivet 2, and the protrusion is used to make the rivet 2 be press-fitted in the perforation 3. The protrusion structure is relatively simple, which is convenient for press-fitting. Press-fitting has the advantages of simple structure and firm connection, and can be easily disassembled by setting a small interference amount.

[0036] Regarding the specific arrangement of the protrusion. The rivet 2 includes a rivet head 6 and a rivet shank 7, and the protrusion is located on the outer periphery of the rivet shank 7, and one side of the protrusion is in contact with the rivet head 6. This can avoid the problem of waste caused by the unused gap when there is a gap between the protrusion and the rivet head 6.

[0037] In this embodiment, the protrusion is an annular protrusion 5, and its dimension along the length direction of the rivet rod 7 is one-third of the length of the rivet rod 7.

[0038] Regarding the application of the integral angle code member, it is mainly realized by a riveting tool. Specifically, referring to Figures 5 to 8 As shown, the riveting tool includes a linear driver 8. A positioning frame is installed at the output end of the linear driver 8. The positioning frame includes two parallelly arranged clamping plates 9. The extending directions of the two clamping plates 9 are the same as the length direction of the linear driver 8. The two clamping plates 9 are used to clamp the angle code from both sides of the width of the angle code; a transverse baffle 15 is also connected between the two clamping plates 9. The transverse baffle 15 is used to abut against the long side of the angle code to cooperate with the output end of the linear driver 8 for riveting.

[0039] For the convenience of introduction, it is defined that the side of the two clamping plates 9 close to the linear driver 8 is the left side. The two clamping plates 9 both include an outward expanding section 10 on the left side and an inward contracting section 11 on the right side. The outward expanding section 10 is used for fixedly connecting with the linear driver 8, and the inward contracting section 11 is used for clamping the angle code to improve the compactness of the whole structure. The outward expanding section 10 and the inward contracting section 11 are integrally formed by an inclined plate.

[0040] Specifically, the outward expanding section 10 is connected to the linear driver 8 through a bolt 12. In this embodiment, the linear driver 8 is a cylinder, and a pressing plate 14 for riveting is connected to the output end of the cylinder.

[0041] In addition to improving the compactness of the whole structure. The left end of the inclined plate abuts against the right end of the cylinder to position the cylinder. The pressing plate 14 reciprocates between the inward contracting sections 11 of the two clamping plates 9. With such a setting, when assembling, the end of the cylinder can be directly abutted against the left end of the inclined plate, improving the assembly efficiency.

[0042] Regarding the size of the pressing plate 14. The width of the pressing plate 14 is adapted to the distance between the inward contracting sections 11 of the two clamping plates 9, so that the pressing plate 14 can be guided to move along the inward contracting section 11. With such a setting, the two clamping plates 9 also guide the pressing plate 14, improving the stability of the movement of the pressing plate 14 and further ensuring the stability of the riveting between the angle code, the rivet 2 and the material to be riveted.

[0043] Finally, the transverse baffle 15 also has a semi-circular groove 13 corresponding to the rivet head 6 of the rivet 2, so as to facilitate the placement of the rivet head 6 when the transverse baffle 15 abuts against the angle code, avoiding the deviation of the rivet head 6 during riveting. The semi-circular groove 13 pre-positions the rivet head 6, further improving the positioning effect.

[0044] The working principle of the riveting tool is as follows: Using the frame 16 to be riveted as the material to be riveted, the integrated angle code piece is sleeved on the frame plate of the frame 16 to be riveted. Through holes for the rivets 2 to pass through are correspondingly arranged on the frame plate of the riveting frame. Then, the riveting tool is used to respectively abut against the wide side and the long side of the angle code through the two clamping plates 9 and the transverse baffle 15 to position the integrated angle code piece. The rivet head 6 of the angle code piece is clamped in the arc-shaped groove of the transverse baffle 15, further improving the positioning effect. Then, the air cylinder is started, and the output end of the air cylinder applies a force to the rivet rod 7 through the pressing plate 14, Figure 6 The arrow direction in [Figure 108] shows the force application direction of the pressing plate 14, and thus the stable riveting among the angle code, the rivets 2 and the frame 16 to be riveted is completed.

[0045] Embodiment 2 of the integrated angle code piece provided by the present utility model:

[0046] The main difference from Embodiment 1 is that:

[0047] In Embodiment 1, the protrusion is an annular protrusion, and its dimension along the length direction of the rivet rod is one-third of the length of the rivet rod.

[0048] In this embodiment, as shown in Figure 9 Figure 117, the protrusion is a plurality of strip-shaped protrusions 17, and the plurality of strip-shaped protrusions 17 are evenly distributed at intervals in the circumferential direction of the rivet rod. The dimension of each strip-shaped protrusion along the length direction of the rivet rod is one-third of the length of the rivet rod.

[0049] Embodiment 3 of the integrated angle code piece provided by the present utility model:

[0050] The main difference from Embodiment 1 is that:

[0051] In Embodiment 1, the angle code is an L-shaped plate, a perforation 3 is provided on one side plate of the L-shaped plate, and a mounting hole 4 for connecting with other devices is provided on the other side plate.

[0052] In this embodiment, as shown in Figure 10 Figure 126, the angle code is a flat plate structure, and both the perforation 3 and the mounting hole 4 are provided on the flat plate.

[0053] Based on the above description of this specification, those skilled in the art can also understand the following terms used. For example, terms indicating orientation or positional relationship such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings of this specification. They are only for the purpose of facilitating the description of the solution of the present utility model and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or positional relationship cannot be understood or interpreted as a limitation to the solution of the present utility model.

[0054] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
