Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a dovetail bolt for a track groove. Background Art

[0002] A track groove is the concave and convex part in a large or small sliding door track, mainly playing the role of supporting and guiding a sliding carriage or a door leaf to slide smoothly on the track. When installing the track groove, tapping is usually carried out on the track groove, and then bolts are used to connect the track groove with the installation surface.

[0003] When installing a track groove with a longer inner groove and multiple bolts are needed to fix the position of the track groove at one time, the bolts are likely to fall off from the hands of the installer when holding multiple bolts. Moreover, for a dovetail track groove, bolts with a wider tail are not easy to enter the inside of the track groove, resulting in inconvenient installation and reduced installation efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when installing a track groove with a longer inner groove and multiple bolts are needed to fix the position of the track groove at one time, the bolts are likely to fall off from the hands of the installer when holding multiple bolts, and for a dovetail track groove, bolts with a wider tail are not easy to enter the inside of the track groove, resulting in inconvenient installation and reduced installation efficiency. A dovetail bolt for a track groove is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A dovetail bolt for a track groove includes a screw rod, the top end of the screw rod is fixedly connected with a screw head, a cross groove is opened at the top end of the screw head, a convenient component for temporarily fixing the whole bolt inside the track groove for taking and using is arranged inside the screw head, and an auxiliary component for facilitating the control of the rotation of the screw head and the screw rod is arranged at the top end of the screw head.

[0006] The effects achieved by the above components are as follows: When using the bolt to install and fix the track groove, tapping and opening holes are carried out in the groove of the track groove. Then, several screw rods are placed into the groove. The bolts are temporarily fixed inside the track groove through the convenient component for easy taking of the bolts. Then, the screw rods are inserted into the threaded holes, and a tool is inserted into the cross groove at the top end of the screw head to control the rotation of the screw rod and screw it into the track groove to install the track groove.

[0007] Preferably, the convenient component includes a cylinder and a round rod. Two rectangular grooves are formed inside the screw head. One end of the inner wall of each of the two rectangular grooves is fixedly connected with a baffle. The cylinder and the round rod are respectively located inside the two rectangular grooves. The ends of the cylinder and the round rod away from each other are fixedly connected with bumps. The round rod slides inside the inner wall of the cylinder. Springs are respectively arranged on the outer surfaces of the cylinder and the round rod. Two ends of each of the two springs are fixedly connected with one side of the cylinder and one side of the inner wall of the rectangular groove, and with one side of the round rod and one side of the inner wall of the rectangular groove. When one side of the bump fits against one side of the baffle, the springs inside the rectangular groove are in a compressed state.

[0008] The effects achieved by the above components are as follows: When using bolts to fix the track groove, the screw head can be inserted into the groove of the track groove. When the screw head is located inside the groove, the compressed springs inside the two rectangular grooves will respectively push the cylinder and the round rod to move outward along the inner wall of the rectangular groove, causing the two bumps to move away from each other. The two bumps are abutted against both sides of the inner wall of the dovetail track groove, enabling the screw head and the screw rod to be suspended inside the groove, temporarily fixing multiple bolts inside the groove, facilitating the installer to pick and use, and improving the efficiency when installing the track groove.

[0009] Preferably, the upper and lower edges of the side of the bump away from the round rod and the cylinder are flat surfaces.

[0010] The effects achieved by the above components are as follows: By setting the upper and lower edges of the side of the bump away from the round rod and the cylinder as flat surfaces, it is not easy for the bump to slide autonomously when it abuts against the inner wall of the track groove.

[0011] Preferably, a positioning component is arranged on the outer surface of the screw head. The positioning component includes a positioning ring. The positioning ring is made of elastic rubber material. First and second annular grooves are formed on the outer surface of the screw head. The first annular groove is located outside the rectangular groove, and the second annular groove is located below the first annular groove. The diameter of the first annular groove is larger than that of the second annular groove.

[0012] The effects achieved by the above components are as follows: When temporarily fixing the bolt inside the track groove through the convenient component, the rubber positioning ring can be tied at the second annular groove for standby. When the screw rod needs to be screwed into the threaded hole for installing the track groove, push the two bumps to make one side of the bump fit against one side of the two baffles to compress the springs inside the rectangular groove. Then, put the rubber positioning ring on the first annular groove. The position of the two bumps inside the screw head is fixed by the tightened rubber positioning ring, so that the bumps will not protrude from the screw head to affect the normal use of the bolt.

[0013] Preferably, a convex piece is fixedly connected to the top end of the positioning ring, and a groove is formed on one side of the convex piece.

[0014] The effects achieved by the above components are as follows: When the rubber positioning ring is tied to the first annular groove or the second annular groove, the convex tab can be pinched at the groove on one side to pull the convex tab, causing the side of the positioning ring close to the convex tab to deform, facilitating the taking of the positioning ring.

[0015] Preferably, the auxiliary component includes a bent rod. A fan-shaped groove is provided at the top end of the screw head. Both ends of the bent rod rotate on both sides of the inner wall of the fan-shaped groove, and a magnetic block is fixedly connected to one side of the bent rod.

[0016] The effects achieved by the above components are as follows: When installing and fixing the track groove through bolts, the bent rod can be pinched to make the bent rod rotate perpendicular to the screw head. Then, by twisting the bent rod, the screw head and the screw can be rotated to facilitate screwing the screw into the threaded hole. After the installation is completed, pushing the bent rod to rotate makes the magnetic block on one side of the bent rod magnetically attract the iron screw head, and the bent rod can be fixed in the fan-shaped groove.

[0017] Preferably, a semi-circular groove is provided on one side of the inner wall of the fan-shaped groove, and the semi-circular groove is located on one side of the top end of the inner wall of the fan-shaped groove.

[0018] The effects achieved by the above components are as follows: When the bent rod needs to be used, it can be hooked on the surface of the bent rod at the semi-circular groove with the hand to more conveniently rotate the bent rod out of the fan-shaped groove.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0020] In the present utility model, by providing a convenient component, when using bolts to fix the track groove, the screw head can be inserted into the groove of the track groove, and the two convex blocks are abutted against both sides of the inner wall of the dovetail track groove, so that the screw head and the screw can be suspended in the groove, and multiple bolts can be temporarily fixed in the groove, facilitating the installer to take and use, and improving the efficiency when installing the track groove.

Detailed implementation mode

[0027] Example 1, as Figure 1-2 shown, a dovetail bolt for an orbital groove includes a screw rod 1. The top end of the screw rod 1 is fixedly connected with a screw head 4. A cross slot 5 is opened at the top end of the screw head 4. Inside the screw head 4, there is a convenient component 2 for temporarily fixing the whole bolt inside the orbital groove for taking and using. At the top end of the screw head 4, there is an auxiliary component 3 for controlling the rotation of the screw head 4 and the screw rod 1. When installing and fixing the orbital groove with the bolt, thread tapping and hole opening are carried out in the groove of the orbital groove. Then, several screw rods 1 are placed into the groove. The bolt is temporarily fixed inside the orbital groove through the convenient component 2 for easy taking of the bolt. Then, the screw rod 1 is inserted into the threaded hole, and a tool is inserted into the cross slot 5 at the top end of the screw head 4 to control the rotation of the screw rod 1 and screw it into the orbital groove for installing the orbital groove.

[0028] Refer to Figure 1-3 shown, in this implementation scheme: The convenient component 2 includes a cylinder 23 and a round rod 25. Inside the screw head 4, two rectangular slots 21 are opened. At one end of the inner walls of the two rectangular slots 21, baffles 22 are respectively fixedly connected. The cylinder 23 and the round rod 25 are respectively located inside the two rectangular slots 21. The ends of the cylinder 23 and the round rod 25 away from each other are respectively fixedly connected with bumps 26. The round rod 25 slides inside the inner wall of the cylinder 23. Springs 24 are respectively arranged on the outer surfaces of the cylinder 23 and the round rod 25. The two ends of the two springs 24 are respectively fixedly connected with one side of the cylinder 23 and one side of the inner wall of the rectangular slot 21, and with one side of the round rod 25 and one side of the inner wall of the rectangular slot 21. When one side of the bump 26 is attached to one side of the baffle 22, the springs 24 inside the rectangular slot 21 are in a compressed state. When using the bolt to fix the orbital groove, the screw head 4 can be inserted into the groove of the orbital groove. When the screw head 4 is inside the groove, the compressed springs 24 inside the two rectangular slots 21 will respectively push the cylinder 23 and the round rod 25 to move outward on the inner walls of the rectangular slots 21, making the two bumps 26 move away from each other, and pressing the two bumps 26 against both sides of the inner wall of the dovetail orbital groove, so that the screw head 4 and the screw rod 1 can be suspended inside the groove, temporarily fixing multiple bolts inside the groove, facilitating the installer to take and use, and improving the efficiency when installing the orbital groove.

[0029] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, in this embodiment: The upper and lower edges of the side of the bump 26 away from the round rod 25 and the cylinder 23 are flat surfaces. By setting the upper and lower edges of the side of the bump 26 away from the round rod 25 and the cylinder 23 as flat surfaces, it is not easy for the bump 26 to slide on its own when it abuts against the inner wall of the track groove. A positioning component 27 is arranged on the outer surface of the screw head 4. The positioning component 27 includes a positioning ring 273. The positioning ring 273 is made of elastic rubber material. A first annular groove 271 and a second annular groove 272 are formed on the outer surface of the screw head 4. The first annular groove 271 is located outside the rectangular groove 21, and the second annular groove 272 is located below the first annular groove 271. The diameter of the first annular groove 271 is larger than the diameter of the second annular groove 272. When temporarily fixing the bolt in the track groove through the convenient component 2, the rubber positioning ring 273 can be tied at the second annular groove 272 for standby. When it is necessary to screw the screw rod 1 into the threaded hole for installing the track groove, push the two bumps 26 to make one side of the bump 26 fit against one side of the two baffles 22 to compress the spring 24 inside the rectangular groove 21. Then, put the rubber positioning ring 273 on the first annular groove 271. The position of the two bumps 26 inside the screw head 4 is fixed by the tightened rubber positioning ring 273, so that the bumps 26 will not protrude from the screw head 4 to affect the normal use of the bolt. The top end of the positioning ring 273 is fixedly connected with a convex piece 274. A groove is formed on one side of the convex piece 274. When tying the rubber positioning ring 273 at the first annular groove 271 or the second annular groove 272, the convex piece 274 can be pinched at the groove on one side of the convex piece 274 to pull the convex piece 274 to deform the side of the positioning ring 273 close to the convex piece 274, which is convenient for taking the positioning ring 273.

[0030] Referring to Figure 1 and Figure 4 As shown, in this embodiment: The auxiliary component 3 includes a bent rod 32. A sector-shaped groove 31 is formed at the top end of the screw head 4. Both ends of the bent rod 32 rotate on both sides of the inner wall of the sector-shaped groove 31. A magnetic block 33 is fixedly connected to one side of the bent rod 32. When installing and fixing the track groove with a bolt, the bent rod 32 can be pinched to make the bent rod 32 rotate to be perpendicular to the screw head 4, and then by twisting the bent rod 32, the screw head 4 and the screw rod 1 can be controlled to rotate to facilitate screwing the screw rod 1 into the threaded hole. After the installation is completed, push the bent rod 32 to rotate so that the magnetic block 33 on one side of the bent rod 32 is magnetically attracted to the iron screw head 4, and the bent rod 32 can be fixed in the sector-shaped groove 31. A semi-circular groove 34 is formed on one side of the inner wall of the sector-shaped groove 31. The semi-circular groove 34 is located at the top side of the inner wall of the sector-shaped groove 31. When it is necessary to use the bent rod 32, it is more convenient to hook the surface of the bent rod 32 at the semi-circular groove 34 with the hand to turn the bent rod 32 out of the sector-shaped groove 31.

[0031] Working principle: When installing the track groove with bolts, thread tapping holes are made inside the groove of the track groove, and several screw heads 4 can be inserted into the groove of the track groove. When the screw head 4 is located inside the groove, the springs 24 compressed inside the two rectangular grooves 21 will respectively push the cylinder 23 and the round rod 25 to move outward along the inner wall of the rectangular groove 21, causing the two bumps 26 to move away from each other and abut against both sides of the inner wall of the dovetail track groove, so that the screw head 4 and the screw rod 1 can be suspended inside the groove, and multiple bolts are temporarily fixed inside the groove. When using a single bolt, the rubber positioning ring 273 at the second annular groove 272 on the surface of the screw head 4 of the bolt is taken out and sleeved on the first annular groove 271 to limit the positions of the two bumps 26 inside the screw head 4. Then, one end of the screw rod 1 is inserted into the threaded hole on the inner wall of the track groove, and the curved rod 32 is pinched to make the curved rod 32 rotate perpendicular to the screw head 4. By twisting the curved rod 32, the screw head 4 and the screw rod 1 are controlled to rotate, and the screw rod 1 is screwed into the threaded hole. Then, the curved rod 32 is pushed to rotate, and the magnet 33 on one side of the curved rod 32 is attached to the inner wall of the fan-shaped groove 31 and magnetically attracted to the screw head 4 to fix the curved rod 32 inside the fan-shaped groove 31. Or a tool is inserted into the cross slot 5 at the top of the screw head 4 to control the rotation of the screw head 4 and the screw rod 1. Subsequently, the remaining bolts are screwed into the threaded holes in the same way to install the track groove.
