Description

Technical fields:

[0001] This utility model relates to the field of hardware products technology, and more specifically to a splicing connector for splicing frames. Background technology:

[0002] Existing splicing frames, such as rectangular frames, are generally composed of multiple vertical and horizontal ribs. Each horizontal and vertical rib is connected by a splicing connector. The existing splicing connectors are generally formed by four connecting columns on the top, bottom, and two side walls of the main body, or by two connecting columns on two side walls and one connecting column on the top or bottom surface, to achieve four-way or three-way connections. Four-way connections are suitable for connections in the middle of the frame, while three-way connections are suitable for connections at the top or bottom of the frame. Their adaptability is limited, and it is not possible to change four-way connections to three-way connections or three-way connections to four-way connections as needed. Utility model content:

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a splicing connector for splicing frames. It can install top connecting columns on the splicing connector body as needed to achieve a four-connecting-column form, or it can remove the top connecting columns as needed to achieve a three-connecting-column form, thereby meeting the connection needs of different positions. It has good performance and a wide range of applications.

[0004] The solution of this utility model to the aforementioned technical problem is:

[0005] A splicing connector for a splicing frame includes a splicing connector body, wherein a downwardly extending lower connecting column is formed on the bottom surface of the splicing connector body, and a transverse connecting column is formed on two adjacent side walls of the splicing connector body.

[0006] The top surface of the splice body has a downwardly extending insertion hole formed in the middle, and the lower part of the top connecting column is inserted into the insertion hole.

[0007] The two horizontal connecting columns are perpendicular to each other.

[0008] The horizontal connecting column, the lower connecting column, and the top connecting column are all rectangular connecting columns.

[0009] The bottom surface of the transverse connecting column is formed with an axially extending insertion groove, and the outer end of the insertion groove extends out of the outer end of the transverse connecting column.

[0010] A central through groove is formed in the middle of the top surface of the insertion groove. A transverse elastic part is formed on one side wall near the outer end of the central through groove. The transverse elastic part is located in the central through groove, and its bottom surface at its inner end extends downward, with its bottom surface extending out of the top surface of the insertion groove.

[0011] The insertion hole is a rectangular hole, and the lower locking part of the top connecting post is rectangular. Multiple axially extending protrusions are formed on its outer side wall, and the outer side wall of the protrusions presses against the inner side wall of the insertion hole.

[0012] The outstanding effect of this utility model is:

[0013] Compared with existing technologies, it can install top connecting columns on the splice body as needed to achieve a four-connecting-column configuration, or remove the top connecting columns as needed to achieve a three-connecting-column configuration, thus meeting the connection needs of different positions, with good performance and wide applicability.

[0022] Example 1, see as follows Figures 1 to 5 As shown, a splicing connector for a splicing frame includes a splicing connector body 10, the bottom surface of which is formed with a downwardly extending lower connecting post 11, and two adjacent side walls of the splicing connector body 10 are each formed with a transverse connecting post 12.

[0023] The top surface of the splice body 10 has a downwardly extending insertion hole 13 formed in the middle, and the lower locking part of the top connecting post 20 is locked in the insertion hole 13.

[0024] The two horizontal connecting columns 12 are perpendicular to each other.

[0025] The horizontal connecting column 12, the lower connecting column 11, and the top connecting column 20 are all rectangular connecting columns.

[0026] The bottom surface of the transverse connecting post 12 is formed with an axially extending insertion groove 121, the outer end of which extends out of the outer end of the transverse connecting post 12. The top surface of the transverse connecting post 12 is also formed with an axially extending upper insertion groove, the outer end of which extends out of the outer end of the transverse connecting post 12.

[0027] A central through groove is formed in the middle of the top surface of the insertion groove 121. A transverse elastic part 122 is formed on one side wall near the outer end of the central through groove. The transverse elastic part 122 is located in the central through groove, and its bottom surface at its inner end extends downward, with its bottom surface extending out of the top surface of the insertion groove 121.

[0028] When this structure is connected, its transverse connecting post 12 can be inserted into the end hole of the corresponding transverse connecting rod, and the bottom surface of the end hole is formed with an elongated protrusion strip, which is inserted into the corresponding insertion groove 121 to achieve connection. At the same time, the bottom surface of the inner end of the transverse elastic part 122 presses against the top surface of the elongated protrusion strip to increase friction and achieve a firm insertion connection.

[0029] Furthermore, the insertion hole 13 is a rectangular hole, and the lower locking part of the top connecting post 20 is rectangular, with multiple axially extending protrusions 21 formed on its outer side wall. The outer side wall of the protrusions 21 presses against the inner side wall of the insertion hole 13. The protrusions 21 increase the friction between the lower locking part of the top connecting post 20 and the insertion hole 13, thereby improving the connection's firmness.

[0030] Both the lower connecting post 11 and the top connecting post 20 include an L-shaped main connecting part 1 and a cross-shaped locking extension part 2. The bottom surfaces of the main connecting part 1 and the cross-shaped locking extension part 2 of the top connecting post 20 are formed on the top surface of the lower locking part of the top connecting post 20, and the top surfaces of the main connecting part 1 and the cross-shaped locking extension part 2 of the lower connecting post 11 are formed on the bottom surface of the splice body 10.

[0031] A slot 3 is formed between the main connecting part 1 and the cross-shaped locking extension part 2.

[0032] When the above structure is used for vertical rod connection, an extended connecting part is formed at the end of the vertical rod, which cooperates with the insertion slot 3, thereby improving the connection effect.

[0033] In this embodiment, the top connecting column 20 and the splice body 10 are detachable structures. Of course, they are generally not disassembled after installation, otherwise the firmness of the snap-fit ​​connection will be affected.

[0034] Example 2, see Figures 6 to 8As shown, a middle locking part 131 is formed on the inner side wall of the middle part of the insertion hole 13. The four side walls of the lower locking part of the top connecting post 20 are all formed with slots 25. The middle locking part 131 is inserted into the corresponding slots 25. The outer side wall of the lower locking part of the top connecting post 20 is pressed against the inner side wall of the insertion hole 13. The top surface of the middle locking part 131 is an inclined wall surface that extends obliquely from the outside to the inside and downward.

[0035] This structure connects the middle locking part 131 to the lower locking part of the top connecting post 20, improving the connection effect. At the same time, the connection at this time makes the two firmly connected and basically impossible to disassemble again. Meanwhile, the structure of the top connecting post 20 and the lower connecting post 11 at this time is different from that in embodiment 1. It needs to be connected with a corresponding vertical rod. The vertical rod can be a rod with a rectangular insertion hole directly formed at the end, which is a conventional structure and will not be described in detail here.

[0036] Meanwhile, no transverse elastic part 122 or other structures are provided at its transverse connecting column 12, and the rest is the same as in embodiment 1.

[0037] In this embodiment, the top connecting column 20 and the splice body 10 are separate parts. When used as the top and bottom connection of the frame, the top connecting column 20 does not need to be installed. When used as the middle connection of the frame, the top connecting column 20 needs to be installed to meet the installation requirements. It has good performance and wide applicability.

[0038] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
