In building structures such as support frames, walls, and floors, connectors are used to connect steel beams, concrete, and other construction materials to ensure structural stability and safety.

[0003] To increase installation flexibility, the connector of a connecting device is provided with an elongated hole through which a fastener is inserted and secured in place. The fastener's installation position can be freely adjusted along the length of the elongated hole, thereby increasing the installation flexibility of the connecting device. However, while the fastener can adjust its installation position along the elongated hole, it also cannot circumferentially contact and fully support the connector. Even if the fastener is secured in place along the elongated hole, the connector is not fully secured. In this case, additional supporting and securing structures are required to secure the connector, which complicates the structure of the connecting device and increases costs.

[0032] Example 1

[0033] Figure 1 A schematic diagram of the main structure of the connecting piece of the utility model is shown. Figure 2 The figure shows a schematic diagram of the main structure of the pressure block in the connecting piece of the present invention. Figure 3 The figure shows a partial three-dimensional structural diagram of the support frame of the present invention. Figure 1 、 Figure 2 and Figure 3 The connecting device includes a connecting member 1 and a pressing block 2. The connecting member 1 is provided with an elongated hole 11, and the fastener 5 can be installed at any position along the elongated hole 11, thereby improving the flexibility of the installation of the fastener 5. The pressing block 2 is provided with a through hole 21 for the fastener 5 to pass through. The pressing block 2 is provided with a first tooth portion 22 extending from the surface of the connecting member 1.

[0034] Among them, the surface of the connector 1 facing the pressing block 2 is also provided with a first groove 12. When the pressing block 2 is attached to the connector 1, the first tooth portion 22 of the pressing block 2 extends into the first groove 12, and the through hole 21 passes through the elongated hole 11. The first tooth portion 22 and the first groove 12 can transmit force between the pressing block 2 and the connector 1. At this time, the fastener 5 passes through the through hole 21 of the pressing block 2 and then through the elongated hole, that is, the side circumference of the fastener 5 is supported by the pressing block 2, and the fastener 5 can transmit force to the connector 1 through the pressing block 2. After the fastener 5 passes through the through hole 21 and the elongated hole 11 and is fixed in the installation position, the fastener 5 can effectively support the connector 1 through the pressing block 2, without the need to set up additional supporting and fixing structures, which greatly simplifies the structure of the connecting device and reduces the cost of the connecting device.

[0035] Preferably, the fastener 5 can be a screw, a stud, a bolt or a nail, etc. The rod of the fastener 5 passes through the through hole 21 and the long hole 11 and is supported by the pressing block 2. The end of the fastener 5 with a diameter larger than the rod contacts the surface of the pressing block 2 away from the connector 1 to ensure that the pressing block 2 is attached to the connector 1.

[0036] Figure 4 A cross-sectional view of the connecting piece at point A of the connecting piece of the present invention is shown. Figure 5 The figure shows the side view of the pressing block in the connector of the present invention. Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the first groove 12 is connected to the elongated hole 11. A boss 23 is extended on the pressing block 2, and the boss 23 is connected to the first tooth portion 22. The length and width of the boss 23 are smaller than the length and width of the elongated hole 11. When the pressing block 2 is fitted with the connector 1, the boss 23 extends into the elongated hole 11. At this time, the root of the first tooth portion 22 is directly connected to the main body of the pressing block 2, and the side of the first tooth portion 22 is supported by the boss 23 of the pressing block 2. That is, the root and side of the first tooth portion 22 have connection supports, which increases the structural strength of the first tooth portion 22, thereby enhancing the stability of the pressing block 2 and the connector 1 when fitted.

[0037] Preferably, the cross section of the first tooth portion 22 is triangular, and correspondingly, the cross section of the first groove 12 is also triangular. Such a shape is more stable, and the first tooth portion 22 and the first groove 12 can withstand a greater load when intersecting, thereby enhancing the stability of the pressing block 2 and the connecting member 1 when they are attached.

[0038] Please refer to Figure 1 and Figure 2At least two first grooves 12 are provided along the length of the elongated hole 11. At least two first teeth 22 are provided. When the pressing block 2 is attached to the connector 1, all first teeth 22 extend into different first grooves 12. The one-to-one correspondence between the multiple first grooves 12 and the multiple first teeth 22 effectively disperses the force and enhances the stability of the pressing block 2 and the connector 1 when attached.

[0039] Preferably, at least two first grooves 12 are provided, and two or more first grooves 12 are provided on both sides of the two long sides of the elongated hole 11. At least two first teeth 22 are provided, and when the pressing block 2 is fitted with the connector 1, all the first teeth 22 extend into different first grooves 12 respectively. Along the width direction of the elongated hole 11, the first grooves 12 on both sides of the elongated hole 11 are staggered. With this arrangement, when the pressing block 2 is fitted with the connector 1, the multiple first legs and the first teeth 22 correspond one-to-one, which can effectively disperse the force. At the same time, the first teeth 22 transmit the force to the first pressing block 2 at multiple points, so that the force on the pressing block 2 is more evenly applied, thereby enhancing the stability of the pressing block 2 and the connector 1 when fitted.

[0040] When at least two first grooves 12 are provided on the same side of the elongated hole 11, second teeth 13 are formed between adjacent first grooves 12, and second grooves 24 are formed between adjacent first teeth 22. At this time, the pressing block 2 is in contact with the connector 1, with the first teeth 22 extending into the first grooves 12 and the second teeth 13 extending into the second grooves 24.

[0041] Figure 6 A cross-sectional view of the connecting piece at point B in the connecting piece of the present invention is shown. Figure 7 The top view of the pressing block in the connector of the present invention is shown. Figure 3 、 Figure 6 and Figure 7 The width of the first groove 12 gradually increases toward the side close to the pressing block 2, making it easier for the first tooth portion 22 to extend into the first groove 12. On the side close to the connecting member 1, the width of the first tooth portion 22 gradually decreases, making it easier for the first tooth portion 22 to extend into the first groove 12. At the same time, the root width of the first tooth portion 22 is larger, providing better structural strength and being able to withstand greater loads.

[0042] Preferably, the connector 1 has at least two elongated holes 11 formed in the same direction. Accordingly, the number of pressing blocks 2 matches the number of elongated holes 11, and each elongated hole 11 is adapted to accommodate a different pressing block 2. Specifically, multiple fasteners 5 can be provided to simultaneously pass through different pressing blocks 2 and the connector 1. The multiple fasteners 5 effectively disperse the force and enhance the connection strength of the connector 1.

[0043] The specific workflow of this utility model is as follows:

[0044] First, secure the structure to be mounted to the connector 1. Then, move the structure to be mounted and the connector 1 to the mounting position. Move the pressing block 2 along the elongated hole 11 to the preset mounting position, and fit the pressing block 2 and the connector 1 together. At this point, the through-hole 21 and the elongated hole 11 are connected, and the first tooth portion 22 extends into the first groove 12. Finally, insert the fastener 5 into the through-hole 21 and the elongated hole 11 to secure the connector 1 and the structure to be mounted on the connector 1 to the mounting position.

The first support member 3 is connected to the connector 1, and the connection method can be welding connection, fastener 5 connection or any other connection method known to those skilled in the art. The pressing block 2 is attached to the connector 1, and at this time the first tooth portion 22 extends into the first groove 12, the connector 1 contacts the second support member 4, and the fastener 5 is connected to the second support member 4 along the through hole 21 and the long hole 11. The end of the fastener 5 with a larger diameter contacts the surface of the pressing block 2 away from the connector 1.

[0047] Preferably, a hole 41 is provided on the second support member 4 for connection with the fastener 5, and the length of the elongated hole 11 on the connecting member 1 is moderate, so that when the connecting member 1 contacts any position of the second support member 4, the fastener 5 can pass through the elongated hole 11 and connect at least one hole 41, that is, the connecting member 1 can be fixed at any position on the second support member 4, and the connection position between the first support member 3 and the second support member 4 can be flexibly adjusted.

[0048] The specific workflow of this utility model is as follows:

[0049] Move the fixed connecting member 1 and the first supporting member 3 to the installation position of the second supporting member 4, move the pressing block 2 along the elongated hole 11 to the predetermined position, and fit the pressing block 2 and the connecting member 1 together. At this time, the through hole 21 and the elongated hole 11 are connected, and the first tooth portion 22 extends into the first groove 12. Insert the fastener 5 along the through hole 21 and the elongated hole 11 until the end of the fastener 5 presses against the surface of the pressing block 2, completing the connection between the first supporting member 3 and the second supporting member 4.
