Description

Technical Field

[0001] This utility model relates to the field of bolt structure technology, specifically to a dust-proof bolt structure. Background Technology

[0002] Bolts are common connecting parts in construction, machinery assembly, equipment installation and other fields. Many bolts now have a slotted end to allow flathead screwdrivers to be inserted to tighten or loosen them. However, in dusty places such as coal mines and construction sites, dust easily accumulates in the slotted end of the bolt, eventually causing blockage. During disassembly and assembly, the screwdriver cannot be directly inserted to rotate the bolt, requiring time-consuming and laborious cleaning, which seriously affects the efficiency of disassembly and assembly.

[0003] Based on this, the present invention designs a dust-proof bolt structure to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a dust-proof bolt structure to solve the above-mentioned technical problems.

[0006] A connecting plate is fixedly connected to the top of the gasket ring. An insertion hole is provided on the outer wall of the connecting plate. A flexible strip is fixedly connected to the end of the insertion rod near the connecting plate. A cone is fixedly provided at one end of the flexible strip. The cone end of the flexible strip is inserted into the insertion hole of the connecting plate.

[0007] Preferably, the end of the bolt rod away from the end head has a protruding thread, and the washer ring is sleeved between the protruding thread of the bolt rod and the end head.

[0008] Preferably, the end is hexagonal and two locking heads are symmetrically engaged on both sides of the end.

[0009] Preferably, the blade groove and the insert rod are both in a straight line shape that fits each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, the insertion rod can be inserted into the blade groove at the end, and the two end clips are engaged with both sides of the end, thereby forming a stable closed structure to prevent dust and impurities from entering the blade groove and accumulating, which would affect subsequent disassembly and assembly.

[0012] Secondly, the washer ring and the insert rod are connected and fitted by a soft strip, a cone head and a connecting plate, and the washer ring is also fitted between the end and the protruding thread, so that the insert rod is not easily lost during disassembly, assembly and transfer.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a dust-proof bolt structure, including: a bolt rod 1 and a washer ring 3; one end of the bolt rod 1 is fixedly connected to an end head 2, the top of the end head 2 is provided with a knife groove 6, an insert rod 7 is embedded in the knife groove 6, and the two ends of the insert rod 7 are respectively fixedly connected to a clip head 8;

[0023] A connecting plate 4 is fixedly connected to the top of the gasket ring 3. An insertion hole 5 is opened on the outer wall of the connecting plate 4. A flexible strip 9 is fixedly connected to the end of the insertion rod 7 near the connecting plate 4 with a clip 8. A cone 10 is fixedly provided at one end of the flexible strip 9. One end of the cone 10 of the flexible strip 9 is inserted into the insertion hole 5 of the connecting plate 4.

[0024] The insertion rod 7 is inserted into the knife groove 6 at the top of the end 2, which covers the knife groove 6. The clips 8 at both ends of the insertion rod 7 will engage with the two sides of the end 2, making the insertion rod 7 stable and not easy to fall out. One end of the flexible strip 9 is fixed to one of the clips 8 of the insertion rod 7, and the other end is directly inserted into the insertion hole 5 of the connecting plate 4 on the gasket ring 3 through the cone 10, which makes it easy to move the insertion rod 7. The cone 10 is made of rubber, which makes it easy to connect with the insertion hole 5 of the connecting plate 4.

[0025] More preferably, the end of the bolt rod 1 away from the end 2 is provided with a protruding thread 11, and the washer ring 3 is sleeved between the protruding thread 11 of the bolt rod 1 and the end 2;

[0026] The other end of the bolt rod 1 is provided with a protruding thread 11, and the washer ring 3 is sleeved between the end 2 and the thread;

[0027] The inner diameter of the washer ring 3 is smaller than that of the end 2 and the protruding thread 11. It slides on the end 2 and the protruding thread 11 of the bolt 1, and the cooperation between them ensures that the insert rod 7 is not easily lost.

[0028] More preferably, the end 2 is hexagonal and two locking heads 8 are symmetrically locked onto both sides of the end 2;

[0029] End 2 is hexagonal, providing greater tool compatibility and not limited to screwdriver assembly and disassembly.

[0030] In a further preferred embodiment, both the knife groove 6 and the insert rod 7 are straight lines that fit together.

[0031] Both the slot 6 and the insert 7 are straight, and their shapes fit each other perfectly. The straight structure is easy to process and easy to connect.

[0032] One specific application of this embodiment is as follows: After the bolt 1 is locked in place by the cooperation of the end 2, the washer ring 3 and the protruding thread 11, the insert rod 7 can be inserted into the slot 6 of the end 2. The two end clips 8 are engaged on both sides of the end 2, thereby forming a stable closed structure to prevent dust and impurities from entering and accumulating in the slot 6. When it is necessary to disassemble or assemble the bolt 1, the operator can manually move the protruding clips 8 to pull out the insert rod 7 in the slot 6. The soft strip 9 will then loosen, and the insert rod 7 will be removed or lifted to expose the slot 6. The screwdriver can then be smoothly inserted into the slot 6 to rotate the entire bolt.
