Description

Technical Field

[0001] This utility model relates to a connection structure. In particular, it relates to a corner connection structure for steering extension connections. Background Technology

[0002] The currently used pipe rack structure can only use connecting pads placed on both sides of a vertical pipe to extend the length of the horizontal pipe in the same direction (e.g., the X-axis or Y-axis). If it is to extend in two dimensions (e.g., simultaneously in the X-axis and Y-axis directions), then because the pipe wall of the vertical pipe is curved, the two ends of the horizontal pipe must be machined to be curved (i.e., concave) to match the curved (i.e. convex) pipe wall of the vertical pipe. Therefore, this leads to increased processing costs and delays in work time. Utility Model Content

[0003] Based on the above reasons, the purpose of this utility model is to provide a corner connection structure that can directly connect a horizontal tube in a first direction (e.g., the X-axis direction) to a base, and then connect another horizontal tube in a second direction (e.g., a positive direction of the Y-axis) perpendicular to the first direction through a first connector; furthermore, it can be connected to yet another horizontal tube in a third direction (e.g., a negative direction of the Y-axis) through a third connector; thereby saving the processing time of the horizontal tube and shortening the overall working time, thus saving costs.

[0004] To achieve the above objectives, the present invention provides a corner connection structure, including a base having a base body portion and a base ring portion, the upper surface of the base body portion being concave; and a first connector extending upward from one end of the base, the first connector being approximately perpendicular to the base such that the first connector and the base are approximately L-shaped, the first connector having a first body portion and a first ring portion, the first body portion being connected to one end of the base body portion, the first ring portion being disposed on the side of the first body portion opposite to the base, the surface of the first body portion adjacent to the base being concave, and the end of the first connector away from the base having a first concave arc slope.

[0005] In some embodiments, the end of the base away from the first connector has a base concave bevel.

[0006] In some embodiments, the end of the base away from the first connector has a base convex bevel.

[0007] In some embodiments, the base body portion has a first hole at its center, the base ring portion is disposed on a lower surface of the base body portion, and the base ring portion has a second hole at its center, the second hole communicating with the first hole.

[0008] In some embodiments, the first connector further includes a first through hole that passes through the first body portion and the first ring portion.

[0009] In some embodiments, the corner connection structure further includes a second connector extending upward from the end of the base away from the first connector. The second connector is substantially perpendicular to the base and substantially parallel to the first connector, such that the first connector, the second connector, and the base are configured in a substantially U-shape. The second connector has a second body portion and a second ring portion. The second body portion is connected to the end of the base body portion away from the first connector. The second ring portion is disposed on the side of the second body portion facing away from the base. The surface of the second body portion facing the first connector is concave.

[0010] In some embodiments, the second connector further includes a second through hole that passes through the second body portion and the second ring portion.

[0011] In some embodiments, the first perforation and the second perforation are substantially coaxial.

[0012] In some embodiments, the end of the second connector away from the base has a second concave bevel.

[0013] In some embodiments, the base body portion, the first body portion, and the second body portion are generally circular, the diameter of the base ring portion is smaller than the diameter of the base ring portion, the diameter of the first ring portion is smaller than the diameter of the first body portion, and the diameter of the second ring portion is smaller than the diameter of the second body portion.

[0014] The advantage of this invention is that it can save the processing time of the horizontal pipe and shorten the overall working time, thereby saving costs. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in detail below with reference to specific circumstances.

[0029] Figure 1This is a perspective view of the first embodiment of the corner connection structure of this utility model. Figure 2 This is a side view of the first embodiment of the corner connection structure of this utility model.

[0030] Please refer to Figure 1 and Figure 2 As shown, the first embodiment of this utility model provides a corner connection structure 10, which may include a base 300 and a first connector 100.

[0031] The base 300 may have a base body portion 310 and a base ring portion 320; the base ring portion 320 is disposed on a lower surface of the base body portion 310 (see reference). Figure 1 and Figure 2 (or orientation). One upper surface of the base body 310 is concave, for example, in Figure 1 and Figure 2 In this embodiment, the upward-facing surface of the base body portion 310 is concave. In some embodiments, the base body portion 310 has a first hole 311 at its center, and the base ring portion 320 has a second hole 321 at its center, the second hole 321 communicating with the first hole 311. In some embodiments, the first hole 311 may be a square hole, and the second hole 321 may be a round hole, but is not limited thereto.

[0032] A first connector 100 may extend upward from one end of the base 300. The first connector 100 may be substantially perpendicular to the base 300, such that the first connector 100 and the base 300 are configured in a substantially L-shape. The first connector 100 may have a first body portion 110 and a first ring portion 120. The first body portion 110 may be connected to one end of the base body portion 310. The first ring portion 120 may be disposed on the side of the first body portion 110 facing away from the base 300. In some embodiments, a surface of the first body portion 110 adjacent to the base 300 may be concave. In some embodiments, the end of the first connector 100 away from the connection with the base 300 has a first concave bevel 111. In some embodiments, the first connector 100 may further include a first through hole 130. The first perforation 130 may pass through the first body portion 110 and the first ring portion 120; for example, the first perforation 130 may pass through the center of the first body portion 110 and the first ring portion 120, but is not limited thereto.

[0033] Please refer to Figure 1 and Figure 2 As shown, in the first embodiment, the base 300 has a base concave arc slope 330 at the end away from the first connector 100. Through the configuration of the base concave arc slope 330 and the first concave arc slope 111, when the horizontal pipe body is connected to the vertical pipe body, the corner connection structure 10 of this utility model will not be exposed, so as to improve the appearance of the pipe rack.

[0034] Figure 3 This is a perspective view of the second embodiment of the corner connection structure of this utility model. Figure 4 This is a side view of a second embodiment of the corner connection structure of this utility model.

[0035] Please refer to Figure 3 and Figure 4 As shown, the corner connection structure 20 of the second embodiment of this utility model is similar to that shown below. Figure 1 and Figure 2 The corner connection structure 10 of the first embodiment shown has the same or similar elements marked with the same element number, and its function and configuration are the same, so it will not be described in detail.

[0036] The difference between the corner connection structure 20 of the second embodiment and the corner connection structure 10 of the first embodiment is that in the corner connection structure 20 of the second embodiment, the end of the base 300 away from the first connector 100 has a base convex arc slope 340. By configuring the base convex arc slope 340, when connecting a horizontal pipe to a vertical pipe, the corner connection structure 20 of this invention can be applied to the side with a shield or the side facing away from the user, reducing the need for complex manufacturing processes. Figure 1 and Figure 2 The procedure and time for the base concave arc slope 330 shown are used to shorten the process and processing time.

[0037] Figure 5 This is a three-dimensional schematic diagram of the third embodiment of the corner connection structure of this utility model. Figure 6 This is a side view of the third embodiment of the corner connection structure of this utility model.

[0038] Please refer to Figure 5 and Figure 6 As shown, the corner connection structure 30 of the third embodiment of this utility model is similar to that shown below. Figure 1 and Figure 2 The corner connection structure 10 of the first embodiment shown has the same or similar elements marked with the same element number, and its function and configuration are the same, so it will not be described in detail.

[0039] The difference between the corner connection structure 30 of the third embodiment and the corner connection structure 10 of the first embodiment is that the corner connection structure 30 of the third embodiment further includes a second connector 200. The second connector 200 extends upward from the end of the base 300 away from the first connector 100. The second connector 200 is substantially perpendicular to the base 300 and substantially parallel to the first connector 100, so that the first connector 100, the second connector 200 and the base 300 are generally arranged in a U-shape. In some embodiments, the second connector 200 may have a second body portion 210 and a second ring portion 220. The second body portion 210 may be connected to the end of the base body portion 310 away from the first connector 100. The second ring portion 220 may be disposed on the side of the second body portion 210 facing away from the base 300. In some embodiments, the surface of the second body portion 210 facing the first connector 100 is concave.

[0040] Please refer to this again. Figure 5 and Figure 6 As shown, the second connector 200 may further include a second through hole 230. The second through hole 230 passes through the second body portion 210 and the second ring portion 220; for example, the second through hole 230 passes through the center of the second body portion 210 and the second ring portion 220, but is not limited thereto. In some embodiments, the first through hole 130 and the second through hole 230 may be substantially coaxially arranged.

[0041] In some embodiments, the end of the second connector 200 away from the connection with the base 300 has a second concave slope 211. In some embodiments, the second concave slope 211 may correspond to the first concave slope 111, but is not limited thereto.

Figure 8 This is a three-dimensional schematic diagram of an L-shaped pipe rack constructed using the corner connection structure of this utility model. Figure 9 The L-shaped pipe rack composed of the corner connection structure of this utility model is used along... Figure 8 A cross-sectional view of section line A-A'. Figure 10 The L-shaped pipe rack composed of the corner connection structure of this utility model is used along... Figure 8 A schematic cross-sectional view along section line B-B'.

[0043] Please refer to Figure 7 As shown, the corner connection structure of this utility model is used (with) Figure 1 and Figure 2 The first embodiment of the corner connection structure 10 is used as an example to form a single tube frame 1A. The corner connection structures 10, 20, and 30 of this utility model must be used in conjunction with a conventional connecting pad 10'.

[0044] Please refer to Figure 8 , Figure 9 and Figure 10 As shown, the corner connection structure of this utility model (with) Figure 1 and Figure 2 The L-shaped pipe rack is formed by the corner connection structure 10 of the first embodiment. Similarly, the corner connection structures 10, 20, and 30 of this utility model all require a conventional connecting pad 10' for use. Figure 8 and Figure 10 In the middle, a first bolt B1 with a square nut B11 can be inserted from a first hole 311 (square hole) in the base 300 of the corner connection structure 10 into a second hole 321 (circular hole); then, as Figure 9 As shown, a second bolt B2 with a stop portion B21 can directly pass through the first body portion 110 of the first connector 100, a vertical tube VP1 (in the Z-axis direction), and a conventional connecting pad 10' in sequence. The direction of the first bolt B1 (e.g., the Y-direction) is perpendicular to the direction of the second bolt B2 (e.g., the X-axis direction). Then, the stop portion B21 of the second bolt B2 abuts against the outside of the first protruding ring portion 120 of the first connector 100 to fix the first connector 100 and the conventional connecting pad 10' to the outside of both sides of the vertical tube VP1, respectively.

[0045] Please refer to Figure 8 and Figure 10 As shown, the first horizontal tube PP1 (in the X-axis direction) can be sleeved and fixed on the base 300 of the corner connection structure 10; in detail, since the diameter of the base ring 320 of the base 300 is smaller than the diameter of the base body 310, one end of the first horizontal tube PP1 can abut against the base body 310, and the base ring 320 tightly fixes the inner surface of the first horizontal tube PP1 to complete an extension in a first direction (i.e., the X-axis direction).

[0046] Please refer to Figure 8 and Figure 9 As shown, a second horizontal tube PP2 (in a positive direction of the Y-axis +Y) can be sleeved and fixed to the first connector 100 of the corner connection structure 10; in detail, since the diameter of the first ring portion 120 of the first connector 100 is smaller than the diameter of the first body portion 110, one end of the second horizontal tube PP2 can abut against the first body portion 110, and the first ring portion 120 tightly fixes the inner surface of the second horizontal tube PP2 to complete the extension in a second direction (i.e., the positive direction of the Y-axis +Y).

[0047] Please refer to this again. Figure 8 and Figure 9As shown, a third horizontal tube PP3 (in a negative Y-axis direction -Y) can be fitted and fixed to a conventional connecting pad 10'; more specifically, one end of the third horizontal tube PP3 can abut against and be fixed to the conventional connecting pad 10' to complete a third-direction extension (i.e., a negative Y-axis direction -Y).

[0048] By extending in the first direction (in the X-axis direction), the second direction (in a positive direction +Y on the Y-axis), and the third direction (in a negative direction -Y on the Y-axis), the L-shaped pipe rack 1B can be completed (e.g. Figure 10 As shown), T-shaped pipe rack 1C (as shown) Figure 11 (as shown) and cross-shaped tube rack 1D (as shown) Figure 12 (as shown), but not limited to this.

[0049] In summary, the corner connection structures 10, 20, and 30 of this utility model can directly connect the first horizontal tube PP1 in the first direction (e.g., the X-axis direction) via the base 300, and then connect the second horizontal tube PP2 in the second direction (e.g., a positive value direction of the Y-axis +Y) perpendicular to the first direction via the first connector 100; even further, it can connect the third horizontal tube PP3 in the third direction (e.g., a negative value direction of the Y-axis -Y) via the second connector 200; thereby saving the processing time of the horizontal tubes (i.e., the first horizontal tube PP1, the second horizontal tube PP2, and the third horizontal tube PP3) and shortening the overall working time, thus saving costs.
