Description

Technical Field

[0001] The utility model relates to the technical field of hexagon socket bolts, in particular to a hexagon socket bolt with a dustproof block. Background Art

[0002] Hexagon socket head bolts have a rounded outer head and a recessed hexagonal center. They are commonly used in machinery, automotive, aerospace, and other fields, offering advantages such as ease of fastening and removal, and resistance to slippage. Choosing a bolt should be tailored to the specific application and torque requirements.

[0003] When using existing hexagon socket bolts, a hexagonal screwdriver needs to be inserted into the hexagonal groove for rotation. After the hexagonal socket bolts are installed, it is inconvenient to seal the hexagonal groove. As time goes by, impurities will adhere to the inner wall of the hexagonal groove, thereby affecting the subsequent rotation of the hexagonal screwdriver and the installation of the hexagonal socket bolt. For this reason, we propose a hexagonal socket bolt with a dust block. Utility Model Content

[0004] The purpose of the utility model is to provide a hexagon socket bolt with a dust block to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A hexagonal socket bolt with a dustproof block comprises a head and a rod, a hexagonal socket groove is provided on the head, and a connecting spring is provided on the bottom wall of the inner cavity of the hexagonal socket groove, a hexagonal dustproof block is provided on the connecting spring, a card slot is provided on both side walls of the hexagonal dustproof block, a through hole connecting the card slot is provided on both side walls of the head, and a fixing component for fixing the card slot is provided in the through hole.

[0007] Further: the fixing component includes a sliding rod, which is slidably connected in the through hole, and a clamping block adapted to the slot is installed at one end of the sliding rod close to the hexagonal dust block, and a compression spring is sleeved on the outer wall of the sliding rod, and the compression spring is located between the outer side surface of the clamping block and the inner wall of the through hole.

[0008] Furthermore: the outer wall of the hexagonal dustproof block is embedded with a corrugated protrusion.

[0009] Furthermore: a pull ring is installed at one end of the slide rod away from the clamping block.

[0010] Furthermore: the handheld end of the pull ring is covered with a non-slip rubber sleeve.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The hexagonal socket bolt of the utility model has a dustproof block. Through the sliding of the sliding rod in the through hole of the fixed component and the elasticity of the compression spring, the clamping block can be connected to or disengaged from the clamping groove. With the elasticity of the connecting spring, the hexagonal dustproof block can be quickly disengaged from the hexagonal socket. After the hexagonal dustproof block is disengaged from the hexagonal socket, the hexagonal screwdriver can be inserted into the hexagonal socket and rotated to realize the disassembly and assembly of the bolt. The operation is convenient, and the overall space occupied is small. The hexagonal socket bolt can be used under different working conditions and has few limitations in use.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1:

[0019] See also Figure 1-3 The utility model provides a technical solution: a hexagonal socket bolt with a dustproof block, comprising a head 1 and a rod 2, a hexagonal socket groove 3 is provided on the head 1, and a connecting spring 11 is provided on the inner bottom wall of the hexagonal socket groove 3, a hexagonal dustproof block 4 is provided on the connecting spring 11, and a card slot 10 is provided on both side walls of the hexagonal dustproof block 4, and a through hole 5 communicating with the card slot 10 is provided on both side walls of the head 1, and a fixing component for fixing the card slot 10 is provided in the through hole 5.

[0020] The head 1 and the rod 2 form a hexagon socket bolt, and the through holes 5 on both sides are connected to the hexagon socket grooves 3, and the two groups of through holes 5 are aligned with the two groups of slots 10 respectively. Through the action of the fixing component, the clamping block 9 can be connected to or disengaged from the slots 10. When the hexagonal dust block 4 is installed, the clamping block 9 is connected to the slots 10. At this time, the connecting spring 11 is in a compressed state after being subjected to the extrusion force. When the hexagonal socket bolt needs to be rotated for installation, the fixing component disengages the clamping block 9 from the slots 10. At this time, the position of the hexagonal dust block 4 is no longer restricted, and the compressed connecting spring 11 bounces off to lift the hexagonal dust block 4, so that the hexagonal dust block 4 can be removed, and the hexagonal screwdriver is then inserted into the hexagonal socket groove 3 and rotated to realize the disassembly and assembly of the bolt. It is easy to operate and the overall space occupied is small. The hexagonal socket bolt can be used under different working conditions and has few limitations on use.

[0021] Among them, preferably, the fixing component includes a slide rod 6, the slide rod 6 is slidably connected in the through hole 5, and a clamping block 9 adapted to the card slot 10 is installed at one end of the slide rod 6 close to the hexagonal dust block 4, and the outer wall of the slide rod 6 is sleeved with a compression spring 8, and the compression spring 8 is located between the outer side surface of the clamping block 9 and the inner wall of the through hole 5;

[0022] The slide rod 6 is fixedly connected to the clamping block 9. When the hexagonal dust block 4 is installed, the slide rods 6 on both sides are pulled outward. At this time, the compression spring 8 is in a compressed state, and the clamping block 9 is received in the through hole 5. Then the hexagonal dust block 4 is placed in the inner hexagonal groove 3 so that the clamping slots 10 on both sides are aligned with the two sets of clamping blocks 9 respectively. Finally, the two sets of slide rods 6 are released, and the compressed compression spring 8 can automatically return to its position. The two sets of clamping blocks 9 move and are connected to the corresponding clamping slots 10, thereby fixing the position of the hexagonal dust block 4. When disassembling, the slide rod 6 is pulled outward to disengage the clamping block 9 from the clamping slot 10. After the position of the hexagonal dust block 4 is no longer restricted, the elastic force of the connecting spring 11 can lift the hexagonal dust block 4.

[0023] Preferably, the outer wall of the hexagonal dust block 4 is embedded with a corrugated protrusion; the corrugated protrusion can increase the friction force in contact with the inner hexagonal groove 3, further improving the stability of the connection between the hexagonal dust block 4 and the inner hexagonal groove 3.

[0024] Preferably, a pull ring 7 is installed at one end of the slide rod 6 away from the clamping block 9; the pull ring 7 facilitates the pulling of the slide rod 6.

[0025] Example 2:

[0026] Reference Figure 3 This embodiment is different from the first embodiment in that the hand-held end of the pull ring 7 is covered with an anti-slip rubber sleeve; the anti-slip rubber sleeve plays an anti-slip role, preventing the hand from slipping when holding the pull ring 7.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
