Description

Bolt easy to tighten and disassemble

Technical Field

The utility model belongs to the technical field of the fastener, specifically speaking especially relates to an easily tightly tear bolt open.

Background

Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.

The bolt is divided into the following parts according to the shape of the head: hexagonal, round, square, countersunk, etc. With a hex head being the most common. The existing inner hexagonal bolt only has one inner hexagonal hole, the selectable inner hexagonal wrench is single, and the mounting and the dismounting cannot be finished without the corresponding inner hexagonal wrench at the hand. Moreover, the bolt can rust after long-term use, and is not easy to disassemble when being disassembled.

SUMMERY OF THE UTILITY MODEL

The utility model provides an easily tightly tear bolt open, can two kinds of hexagon socket head wrenches of adaptation, do not need the spanner to accomplish even and tightly tear the process open, it is very convenient to prior art exist.

The purpose of the utility model can be realized by the following technical scheme: an easy-to-tighten-and-disassemble bolt comprises a head and a screw, wherein threads are arranged on the screw, a hexagon socket A is arranged in the center of the head, a hexagon socket B is arranged in the center of the hexagon socket A, a conical hole is arranged in the center of the hexagon socket B, and the center of the conical hole is communicated with a pipeline;

the pipeline comprises a main pipeline and a branch pipeline, and the branch pipeline is communicated with the outside;

the head part is not provided with a hole vertical to the axial direction in a penetrating way.

Furthermore, the branch pipelines are arranged in a left-right staggered mode.

Furthermore, the specifications of the hexagon socket A and the hexagon socket B are different, and the diameter of the hexagon socket A is larger than that of the hexagon socket B.

Further, the depth of the hole is smaller than the radius of the head.

Furthermore, the diameter of the tapered hole is larger at the top and smaller at the bottom, and the diameter of the tapered hole is equal to the diameter of the pipeline.

The utility model has the advantages that:

1. the head of the utility model is provided with two hexagon socket holes with different specifications, which can be suitable for hexagon socket wrenches with different specifications, and the selectivity is relatively larger;

2. the head of the utility model is not communicated with a hole vertical to the axial direction, when the bolt is tightened or disassembled, a special tool is not needed, only a stick with enough strength is needed, the rotation is realized, and the operation is simple;

3. the utility model discloses be provided with the pipeline, when step up or dismantle the bolt, can pour lubricating oil into, lubricating oil has made things convenient for step up or the dismantlement process of bolt through the pipeline in flowing into the screw thread.

Drawings

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic perspective view of the present invention;

fig. 2 is a schematic sectional structure diagram of the present invention.

In the figure: 1. a head portion; 2. a screw; 3. a thread; 4. an inner hexagonal hole A; 5. a hexagon socket B; 6. a tapered hole; 7. a pipeline; 71. a main pipeline; 72. branch pipelines; 8. and (4) holes.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings: as shown in fig. 1 to 2 in the attached drawings of the specification, the bolt easy to tighten and disassemble comprises a head part 1 and a screw rod 2, wherein a thread 3 is arranged on the screw rod 2, a hexagon socket A4 is arranged in the center of the head part 1, a hexagon socket B5 is arranged in the center of the hexagon socket A4, a tapered hole 6 is arranged in the center of the hexagon socket B5, and a pipeline 7 is communicated with the center of the tapered hole 6;

the pipeline 7 comprises a main pipeline 71 and a branch pipeline 72, and the branch pipeline 72 is communicated with the outside;

the head part 1 is not provided with a hole 8 which is vertical to the axial direction in a penetrating way.

Further, the branch pipes 72 are arranged in a left-right staggered manner.

Furthermore, the specifications of the hexagon socket A4 and the hexagon socket B5 are different, and the diameter of the hexagon socket A4 is larger than that of the hexagon socket B5.

Further, the depth of the hole 8 is smaller than the radius of the head 1.

Further, the diameter of the tapered hole 6 is larger at the top and smaller at the bottom, and the diameter of the lower hole is equal to the diameter of the pipeline 7.

The use principle is as follows:

the utility model relates to an easily tightly tear bolt open, including head 1 and screw rod 2, be provided with screw thread 3 on the screw rod 2, head 1 center is opened has interior hexagonal hole first 4, and interior hexagonal hole first 4 center is opened has interior hexagonal hole second 5, and interior hexagonal hole first 4 is greater than interior hexagonal hole second 5 with the different and interior hexagonal hole first 4's of specification of interior hexagonal hole second 5 diameter. The utility model discloses a head is provided with the interior hexagonal hole of two different specifications, can be suitable for the interior hexagonal spanner of different specifications, and the selectivity is bigger relatively.

The head part 1 is not penetrated and provided with a hole 8 vertical to the axial direction, and the depth of the hole 8 is smaller than the radius of the head part 1. When the bolt is tightened or disassembled, a special tool is not needed, only a stick with enough strength is needed, and the operation is simple.

A tapered hole 6 is formed in the center of the inner hexagonal hole B5, and a pipeline 7 is communicated with the center of the tapered hole 6; the diameter of the conical hole 6 is larger at the upper part and smaller at the lower part, and is equal to the diameter of the pipeline 7. The pipeline 7 comprises a main pipeline 71 and a branch pipeline 72, and the branch pipeline 72 is communicated with the outside; the branch pipes 72 are arranged in a staggered manner from side to side. When the bolt is tightened or disassembled, lubricating oil can be poured into the bolt, and the lubricating oil flows into the threads 3 through the pipeline 7, so that the bolt tightening or disassembling process is facilitated.

The foregoing is merely exemplary and illustrative of the structure of the invention, and various modifications, additions and substitutions as described in the detailed description may be made by those skilled in the art without departing from the structure or exceeding the scope of the invention as defined in the claims.
