[0002] The glass curtain wall bolt tightening force detection device is mainly used to ensure the stability of curtain wall bolts during installation and use. This device usually contains a tool that can apply accurate torque to the bolt, such as a torque wrench, as well as corresponding accessories and sensors. In mechanical structures, the tightening force is achieved by the friction between the bolt and the nut and the friction between the bolt head and the connected parts. These friction forces are proportional to the torque applied to the bolt. Therefore, by measuring the torque applied to the bolt, the tightening force of the bolt can be known.

[0003] According to the publication (announcement) number: CN206216578U, the publication (announcement) date: 2017-06-06, a torque wrench is disclosed, including: a wrench body with a tool head at the end; a torque strain rod arranged in the wrench body and connected to the tool head at one end; a torque sensor, the torque sensor is arranged on the torque strain rod to detect the torque value transmitted from the tool head to the torque strain rod; an angle sensor, the angle sensor is arranged in the wrench body to detect the horizontal angle between the tool head and the wrench body; a circuit board device, the circuit board device is arranged in the wrench body to process the detected torque signal and angle signal; a controller, the controller is wirelessly connected to the wrench body to receive and process the data sent by the circuit board device.

[0004] It can be seen from the above patents and prior art that torque wrenches are suitable for light loads and occasions that do not require high precision. They are cheap and easy to operate. However, when curtain walls are operated at high altitudes, if the bolts of the curtain walls are too large, a larger torque wrench is required. At the same time, a longer torque wrench is also required to achieve a larger torque force. However, it is inconvenient to carry a longer torque wrench at high altitudes, and it is more troublesome to use. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-3 As shown, a glass curtain wall bolt tightening force detection device comprises a torque wrench 1, on which a wrench head 11 is arranged, a sliding cylinder 14 is slidably arranged on the torque wrench 1, and outer shells 13 are symmetrically arranged on both sides of the sliding cylinder 14. The two outer shells 13 are buckled to form a cylinder, and the diameter of the outer shell 13 is larger than the maximum diameter of the torque wrench 1;

[0023] When the outer shell 13 moves onto the anti-slip handle 12 disposed at the bottom of the torque wrench 1 , the outer shell 13 is located at the bottom of the torque wrench 1 , so that the length of the torque wrench 1 is increased.

[0024] Specifically, when in use, first slide the sliding cylinder 14 downward on the torque wrench 1, driving the two cylindrical outer shells 13 to be located on the anti-slip handle 12 at the bottom of the torque wrench 1. At this time, the sliding cylinder 14 is located on the anti-slip handle 12 at the bottom of the torque wrench 1. At this time, the length of the torque wrench 1 becomes longer, and then the wrench head 11 of the torque wrench 1 is placed on the bolt to be tested, and the cylinder composed of the two outer shells 13 is rotated to perform torque testing.

[0025] In the above scheme, the curtain wall bolts are detected by the torque wrench 1 and the wrench head 11, the outer shell 13 is driven to slide by the sliding cylinder 14, and the cylinder composed of the two outer shells 13 and the sliding cylinder 14 drive the outer shell 13 to move to the anti-slip handle 12, thereby increasing the length of the torque wrench 1, and achieving a stronger torque force through the short torque wrench 1.

[0026] As an embodiment further provided by the present invention, according to Figure 1 , Figure 2 and Figure 3As shown, an extension plate 17 is provided at the edge of one of the outer shells 13 , and a plurality of circular grooves 18 arranged in a linear array are formed on the extension plate 17 .

[0027] Furthermore, a fixing portion 21 is disposed at the edge of the other outer shell 13 . The fixing portion 21 is provided with an inserting groove 211 for inserting the extension plate 17 . A plurality of fixing balls 22 corresponding to the circular grooves 18 are disposed in the inserting groove 211 .

[0028] Furthermore, a fixed block 16 is provided at the connection between the outer shell 13 and the sliding cylinder 14 , a rotating block 162 is provided on the fixed block 16 , and the outer shell 13 is rotatably provided on the rotating block 162 .

[0029] Specifically, when working at high altitude, it is not convenient to twist the torque wrench 1. At this time, the two cylindrical outer shells 13 are pried apart. At this time, the outer shell 13 is deflected by the rotating block 162 on the fixed block 16, so that the two outer shells 13 and the torque wrench 1 form a "cross" shape. When the two outer shells 13 are separated, the fixed ball 22 will be disengaged from the circular groove 18. When it is necessary to combine, the two outer shells 13 are pried to wrap the torque wrench 1. At this time, the extension plate 17 will be inserted into the insertion groove 211 opened on the fixing part 21, and the fixed ball 22 will be embedded in the circular groove 18 at the same time to complete the fixation.

[0030] As an embodiment further provided by the present invention, according to Figure 1 , Figure 2 and Figure 3 As shown, a plurality of reinforcing ribs 161 are symmetrically fixedly arranged around the rotating block 162 , and the plurality of reinforcing ribs 161 are all rotatably arranged on the outer shell 13 .

[0031] Specifically, the reinforcing ribs 161 can be used to reinforce the outer shell 13 when it swings to prevent it from breaking.

[0032] As an embodiment further provided by the present invention, according to Figure 1 , Figure 2 and Figure 3 As shown, a fixing groove 15 is provided on the sliding cylinder 14 , and a fixing rod 19 is slidably provided in the outer shell 13 .

[0033] Furthermore, an insert block 23 is slidably disposed on the sliding cylinder 14 .

[0034] Specifically, when the two outer shells 13 and the torque wrench 1 form a "cross" shape, the fixing rod 19 is pushed inward and inserted into the fixing groove 15, and then the insert block 23 is pressed downward to insert the insert block 23 into the slot 20 opened on the fixing rod 19 for fixing.

[0035] Working principle: When in use, first slide the sliding cylinder 14 downward on the torque wrench 1, driving the two outer shells 13 forming a cylindrical shape to be located on the anti-slip handle 12 at the bottom of the torque wrench 1. At this time, the sliding cylinder 14 is located on the anti-slip handle 12 at the bottom of the torque wrench 1. At this time, the length of the torque wrench 1 becomes longer, and then the wrench head 11 of the torque wrench 1 is placed on the bolt to be tested, and the cylinder formed by the two outer shells 13 is rotated to perform torque testing;

[0036] When working at high altitude, it is convenient to twist the torque wrench 1. At this time, the two cylindrical outer shells 13 are broken apart. At this time, the outer shell 13 is deflected by the rotating block 162 on the fixed block 16, so that the two outer shells 13 and the torque wrench 1 form a "cross" shape. When the two outer shells 13 and the torque wrench 1 form a "cross" shape, the fixing rod 19 is pushed inward and embedded in the fixing groove 15, and then the plug block 23 is pressed downward to make the plug block 23 inserted into the slot 20 opened on the fixing rod 19 for fixing.

[0037] It should be noted that when the two outer shells 13 are separated, the fixed ball 22 will be detached from the circular groove 18. When they need to be combined, the two outer shells 13 are bent to wrap the torque wrench 1. At this time, the extension plate 17 will be inserted into the insertion groove 211 opened on the fixing part 21, and the fixed ball 22 will be embedded in the circular groove 18 at the same time to complete the fixation.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
