Description

Technical Field

[0001] This utility model belongs to the technical field of steel rod connectors, and in particular relates to a novel prestressed steel rod connector. Background Technology

[0002] Prestressed steel bar connectors are core connecting components in the field of prestressed engineering. They are mainly used to achieve reliable connection (extension) of two or more prestressed steel bars, or rigid connection between steel bars and anchors or components, ensuring that prestress can be efficiently and stably transferred between steel bars. They are an indispensable key component in prestressed structures such as long-span bridges, high-rise buildings, and pipe pile foundations.

[0003] However, existing prestressed steel bar connectors require a wrench to rotate the device during connection and assembly, which limits their use and makes them inconvenient to operate. Utility Model Content

[0004] The purpose of this invention is to provide a novel prestressed steel bar connector that solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a novel prestressed steel bar connector, comprising: a top seat, a threaded connecting seat fixedly installed at the bottom end of the top seat, an upper steel bar slidably inserted into the threaded connecting seat, and one end of the upper steel bar extending to the outside of the top seat; a connecting body threadedly connected to the bottom end of the top seat via the threaded connecting seat; a lower steel bar slidably inserted into the connecting body; and a rotating mechanism for rotating the connecting body symmetrically fixedly installed on the outer ring of the connecting body; the rotating mechanism includes mounting seats symmetrically fixedly installed on the outer ring of the connecting body, connecting plates rotatably connected to the mounting seats, connecting posts equidistantly spaced between the connecting plates, and two connecting plates fixedly connected by the connecting posts.

[0006] Furthermore, a PC pad is provided between the upper steel bar and the lower steel bar.

[0007] Furthermore, the rotating mechanism also includes a snap-fit ​​part fixedly installed on the end of the connecting plate away from the mounting base. The snap-fit ​​part is L-shaped, and a snap-fit ​​groove is provided on one side of the mounting base to engage with the snap-fit ​​part.

[0008] Furthermore, the outer ring of the connecting plate and the connecting column is provided with anti-slip texture. The anti-slip texture can increase the friction between the connecting plate and the worker's hand, making the connection more stable when rotating and facilitating the worker's work.

[0009] Furthermore, the connecting plate is provided with a lightweight groove in the middle. The lightweight groove can reduce the overall weight of the rotating mechanism, so that the weight deviation after the rotating mechanism is installed on the device is small. At the same time, the lightweight groove can increase the contact area between the connecting plate and the operator's hand, further increasing the friction during use.

[0010] Furthermore, a pressing seat is provided on one side of the card slot, which is pressed and fitted with the connecting plate. When the connecting body needs to be rotated, the connecting plate is rotated 180° along the mounting base, so that the two connecting plates form symmetrical extensions, so that the operator can rotate the connecting body through the connecting plate. In order to increase the stability of the connecting plate during rotation, a pressing seat is provided at the connection between the connecting plate and the mounting base, which can support the connecting plate when it rotates.

[0011] Furthermore, the bottom end of the connector is provided with a rotating groove, which is a regular polygon, making it easy for workers to rotate the connector with a wrench, thereby increasing the connection stability between the threaded connector and the connector, making the device more stable during assembly.

[0012] This utility model has the following beneficial effects: 1. This utility model, through the setting of the rotating mechanism, enables the device to achieve a stable connection between the threaded connector and the connecting body without the aid of a wrench, increasing the convenience of the device during use. In addition, the symmetrical fitting and snap-fit ​​setting of the rotating mechanism can reduce the space occupied by the rotating mechanism, making the fit between the connecting body and the rotating mechanism more stable and convenient for workers to use.

[0013] 2. The lightweight groove in this invention can reduce the overall weight of the rotating mechanism. In addition, the lightweight groove can also increase the friction between the rotating mechanism and the operator's hand when the rotating mechanism is unfolded or folded, making it easier for the operator to rotate the connecting body.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 This utility model is a novel prestressed steel bar connector, comprising: a top seat 1, a threaded connecting seat 2 fixedly installed at the bottom end of the top seat 1, an upper steel bar 3 slidably inserted into the threaded connecting seat 2, and one end of the upper steel bar 3 extending to the outside of the top seat 1; a connecting body 4 threadedly connected to the bottom end of the top seat 1 through the threaded connecting seat 2; a lower steel bar 5 slidably inserted into the connecting body 4; and a rotating mechanism 7 for rotating the connecting body 4 symmetrically fixedly installed on the outer ring of the connecting body 4; the rotating mechanism 7 includes mounting seats 8 symmetrically fixedly installed on the outer ring of the connecting body 4; connecting plates 9 rotatably connected to the mounting seats 8; connecting posts 10 are equidistantly arranged between the connecting plates 9; and the two connecting plates 9 are fixedly connected by the connecting posts 10.

[0020] A PC pad 6 is provided between the upper steel rod 3 and the lower steel rod 5. The PC pad 6 can compress the upper steel rod 3 and the lower steel rod 5, thereby increasing the installation fit between the upper steel rod 3 and the threaded connecting seat 2, and between the connecting body 4 and the lower steel rod 5.

[0021] The rotating mechanism 7 also includes a snap-fit ​​part 13 fixedly installed on the end of the connecting plate 9 away from the mounting base 8. The snap-fit ​​part 13 is L-shaped, and a snap-fit ​​groove 14 is provided on one side of the mounting base 8 to engage with the snap-fit ​​part 13.

[0022] It should be noted that when the rotating mechanism 7 is not needed to rotate the connecting body 4, the connecting plate 9 does not need to be unfolded. The connecting plate 9 is engaged with the locking groove 14 on one side of the mounting base 8 through the locking part 13 at the end, so that the rotating mechanism 7 maintains installation stability when not in use. When the rotating mechanism 7 is needed to rotate the connecting body 4, the connecting plate 9 is pulled to move the locking part 13 out of the locking groove 14. Then, the connecting plate 9 is rotated until the two connecting plates 9 are rotated 180° and form a linear symmetrical arrangement, which makes it convenient for the staff to rotate the connecting body 4.

[0023] The outer ring of the connecting plate 9 and the connecting column 10 is provided with anti-slip texture 11. The anti-slip texture 11 can increase the friction between the connecting plate 9 and the worker's hand, making the connecting body 4 more stable when rotated, and making it easier for the worker to work.

[0024] The connecting plate 9 is provided with a lightweight groove 12 in the middle. The lightweight groove 12 can reduce the overall weight of the rotating mechanism 7, so that the weight deviation after the rotating mechanism 7 is installed on the device is small. At the same time, the lightweight groove 12 can increase the contact area between the connecting plate 9 and the worker's hand, further increasing the friction during use.

[0025] One side of the snap-fit ​​groove 14 is provided with a pressing seat 15, which is pressed and fitted with the connecting plate 9. When it is necessary to rotate the connecting body 4, the connecting plate 9 is rotated 180° along the mounting base 8, so that the two connecting plates 9 form symmetrical extensions, so that the operator can rotate the connecting body 4 through the connecting plate 9. In order to increase the stability of the connecting plate 9 during rotation, the connecting plate 9 and the mounting base 8 are provided with a pressing seat 15, which can support the connecting plate 9 when it rotates.

[0026] The bottom end of the connector 4 is provided with a rotating groove 16. The rotating groove 16 is a regular polygon, which makes it easy for the operator to use a wrench to rotate the connector 4, thereby increasing the connection stability between the threaded connector 2 and the connector 4, making the device more stable during assembly.
