Description

Technical Field

[0001] The utility model specifically relates to a bolt with an adjustable installation angle. Background Art

[0002] A bolt is a type of fastener composed of a bolt head and a screw rod, which needs to cooperate with a nut for fastening and connecting two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the parts can be separated, so the bolt connection belongs to a detachable connection.

[0003] Currently, when a bolt is installed and used, it can only be perpendicular to the installation hole. When the installation hole is inclined, the staff needs to support the screw rod to ensure the stability of the screw rod during installation. Such operations reduce the convenience and safety of bolt installation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bolt with an adjustable installation angle to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A bolt with an adjustable installation angle, including an installation frame, a rotation assembly, a screw rod, and a screwing assembly. The screw rod is installed on the installation frame, and the screw rod rotates relative to the installation frame in the installation direction through the rotation assembly. After the rotation direction of the screw rod is consistent with the direction of the installation hole, the installation of the screw rod is completed through the screwing assembly.

[0006] Preferably, the rotation assembly includes two vertical plates arranged on the installation frame. Rotation holes are formed on the surfaces of the two vertical plates, and a rotating shaft is inserted into the rotation holes.

[0007] Preferably, a rotating block is sleeved outside the rotating shaft, and an insertion hole for inserting the screw rod is formed in the rotating block.

[0008] Preferably, upper threads and lower threads are respectively formed on the upper and lower parts of the screw rod. The screwing assembly includes a screwing nut arranged outside the upper threads of the screw rod.

[0009] Preferably, the screwing assembly further includes a fixing block arranged at the top of the screw rod. A screwing groove is formed on the surface of the fixing block from outside to inside and downward.

[0010] Preferably, a strip-shaped groove for the deflection of the screw rod is formed on the lower surface of the installation frame.

[0011] Preferably, internal threads are formed on the inner wall of the insertion hole.

[0012] Technical effects and advantages of the present utility model: For the bolt with adjustable installation angle, when installing the bolt, place the mounting bracket vertically above the hole to be installed, rotate the screw cap, and make the screw cap rotate on the upper thread of the screw rod. After the screw cap rotates to the end of the upper thread, it can drive the whole screw rod to rotate. At this time, the lower thread of the screw rod is adapted to the internal thread in the jack, so that the screw rod rotates and is inserted into the preset installation hole. When it is necessary to install the screw rod obliquely, rotate the rotating block by rotating the rotating shaft, so that the screw rod follows the deflection. Insert an external pneumatic tool into the screwing groove to drive the screw rod to rotate, so that the screw rod is driven in obliquely. At this time, there is no need to manually support the screw rod, which improves safety and convenience. Description of the Drawings

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] To improve the convenience when the screw rod 2 is installed at a certain angle of deflection, refer to Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes a mounting bracket 1, a rotating assembly, a screw 2, and a screwing assembly. The screw 2 is installed on the mounting bracket 1, and the screw 2 rotates in the installation direction relative to the mounting bracket 1 through the rotating assembly. After the rotation direction of the screw 2 is consistent with the direction of the installation hole, the installation of the screw 2 is completed through the screwing assembly. When installing a bolt, place the mounting bracket 1 vertically above the installation hole to be installed, and rotate the screw cap 7 so that the screw cap 7 rotates on the upper thread of the screw 2. After the screw cap 7 rotates to the end of the upper thread, it can drive the entire screw 2 to rotate. At this time, the lower thread of the screw 2 is adapted to the internal thread in the jack 6, so that the screw 2 rotates and is inserted into the preset installation hole. When it is necessary to install the screw 2 obliquely, rotate the rotating block 5 by rotating the rotating shaft 4, so that the screw 2 follows the deflection. Insert an external pneumatic tool into the screwing groove 9 to drive the screw 2 to rotate, so that the screw 2 is driven in obliquely. At this time, there is no need for manual support of the screw 2, which improves safety and convenience.

[0020] To improve the stability of the screw 2 after installation, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, the rotating assembly includes two vertical plates 3 provided on the mounting bracket 1. When it is necessary to install the screw 2 obliquely, just press the mounting bracket 1 to fix the screw 2 to be installed, avoiding direct pressing of the screw 2 by the staff and improving safety. Both surfaces of the two vertical plates 3 are provided with rotation holes, and a rotating shaft 4 is inserted into the rotation holes. A rotating block 5 is sleeved outside the rotating shaft 4, and a jack 6 for inserting the screw 2 is provided in the rotating block 5. By rotating the rotating shaft 4, the rotating block 5 is driven to rotate, so that the screw 2 deflects in direction and the installation angle of the screw 2 is changed. The upper and lower parts of the screw 2 are respectively provided with upper threads and lower threads. The screwing assembly includes a screw cap 7 provided outside the upper thread of the screw 2. By rotating the screw cap 7, the screw cap 7 rotates on the upper thread. When it rotates to the end of the upper thread, the screw 2 can be driven to rotate. The screwing assembly further includes a fixing block 8 provided at the top of the screw 2. A screwing groove 9 is opened on the surface of the fixing block 8 from outside to inside and downward. When the screw cap 7 is screwed to a certain extent, that is, when it cannot be rotated manually, at this time, the head of the screw 2 has entered the installation object. The output end of the external pneumatic tool is inserted into the screwing groove 9 opened on the upper surface of the fixing block 8, and the screw 2 is rotated to complete the installation of the screw 2. A strip-shaped groove 10 for the deflection of the screw 2 is opened on the lower surface of the mounting bracket 1. When the rotating block 5 drives the deflection of the screw 2, the strip-shaped groove 10 facilitates the lower part of the screw 2 to follow the deflection. The inner wall of the jack 6 is provided with an internal thread, which facilitates the rotation of the screw 2 through the internal thread in the jack 6. When the screw 2 is installed, the mounting bracket 1 is fixed accordingly, thus playing the role of a gasket and further improving the stability of the screw 2 after installation.

[0021] During use, when installing the bolt, place the mounting bracket 1 vertically above the hole to be installed, and rotate the screw cap 7 so that the screw cap 7 rotates on the upper thread of the screw rod 2. After the screw cap 7 rotates to the end of the upper thread, it can drive the entire screw rod 2 to rotate. At this time, the lower thread of the screw rod 2 is adapted to the internal thread in the jack 6, so that the screw rod 2 rotates and is inserted into the preset installation hole. When it is necessary to install the screw rod 2 obliquely, rotate the rotating block 5 by rotating the rotating shaft 4, so that the screw rod 2 follows the deflection. Insert an external pneumatic tool into the screwing groove 9 to drive the screw rod 2 to rotate, so that the screw rod 2 is driven in obliquely. At this time, there is no need for manual support of the screw rod 2, which improves safety and convenience.

[0022] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
