Description

Technical Field

[0001] This utility model relates to the field of T-bolts, and more particularly to an anti-slip T-bolt. Background Technology

[0002] Bolts: Mechanical parts, cylindrical threaded fasteners that are fitted with nuts. They are a type of fastener consisting of a head and a threaded shank (a cylinder with external threads). They need to be used with nuts to fasten two parts with through holes. T-bolts can be directly inserted into aluminum profile slots. During installation, they can automatically position and lock themselves. They are often used with flange nuts and are the standard matching connectors for installing corner fittings. They can be selected and used according to the width of the profile slot and different series of profiles.

[0003] When installing existing T-bolts with devices, some T-bolts have gaps between themselves and the mounting grooves of the devices, which prevents the T-bolts from fitting tightly into the grooves and causes them to slip off. Therefore, we propose an anti-slip T-bolt to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an anti-slip T-bolt to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-slip T-bolt includes: a bolt body, a first shaft fixedly connected to the bottom of the bolt body, a fixed circular plate fixedly connected to the outer side of the first shaft, and a handwheel rotatably connected to the outer side of the first shaft. Two first posts are fixedly connected to the bottom of the handwheel, connecting rods are rotatably connected to the outer sides of the two first posts, and second posts are rotatably connected to the other ends of the two connecting rods. Insert blocks are fixedly connected to the bottom of the two second posts, and connecting strips are fixedly connected to the sides of the two insert blocks that are close to each other. Guide blocks are fixedly connected to the bottom of the two connecting strips, and two sliding grooves adapted to the guide blocks are opened on the top of the fixed circular plate. The outer sides of the two guide blocks are slidably connected in the corresponding sliding grooves.

[0007] Preferably, the top of the handwheel is fixedly connected to two No. 1 rods, and the outer sides of the two No. 1 rods are slidably connected to No. 1 cylinders. The top of the two No. 1 cylinders is fixedly connected to the same lever, and the bottom of the lever is fixedly connected to two springs. The other ends of the two springs are fixedly connected to the top of the handwheel.

[0008] Preferably, the bottom of the bolt body is provided with a cylindrical rod, and the outer side of the cylindrical rod is fixedly connected to the inner side of the lever block. The bottom of the bolt body is fixedly connected with multiple sockets, and the inner side of each of the multiple sockets is provided with a circular groove that matches the cylindrical rod. The outer side of the cylindrical rod is movably inserted into the corresponding circular groove.

[0009] Preferably, a threaded rod is fixedly connected to the bottom of the fixed circular plate, and a threaded groove is opened on the outer side of the threaded rod, and a nut is threadedly connected to the inner side of the threaded groove.

[0010] Preferably, the top of the bolt body has a rotating groove, and a friction pad is fixedly sleeved on the outside of the handwheel.

[0011] Preferably, the bolt body, threaded rod, fixing circular plate, and outer side of shaft No. 1 are all coated with anti-corrosion material.

[0012] In this utility model, an anti-slip T-bolt is installed by inserting the outer side of the threaded rod into the inner side of the corresponding device and continuously rotating the bolt body. When the bolt body is rotated to a certain depth, the nut is rotated to move the top of the nut into contact with one side of the device. At this point, the first layer of bolt fixing is completed. Further, the push block is pressed down to compress the spring and the cylindrical rod leaves the groove. At this point, the handwheel is rotated to make the connecting rod start to rotate, so that the insert block moves horizontally under the limit of the guide block.

[0013] In this utility model, the anti-slip T-bolt is inserted into the inner side of the device by inserting a plug. At this time, when the plug is stopped, the cylindrical rod enters the inner side of the corresponding circular groove under the reset of the spring. At this time, the handwheel is fixed in the position when it stops rotating, thus completing the fixation of the bolt body to the device and preventing the bolt body from slipping out of the device.

[0014] This utility model has a reasonable structural design. Through the cooperation between the handwheel, connecting rod, No. 1 column, No. 2 column, connecting strip, guide block and insert block, the bolt body can be fixed to the device for a second time, thereby preventing the bolt body from slipping out of the non-fitting installation groove.
