Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a long bolt which is easy to operate and screw. Background Art

[0002] Bolts play a vital role in mechanical manufacturing and have numerous functions. Existing long bolts consist of a long rod with an external thread on one end and a hexagonal bolt head on the other. A wrench is commonly used to install and remove the bolts, and people manually turn the wrench to tighten the bolts. However, existing bolts can only tighten the bolt head at the end, making the tightening operation cumbersome when the bolt is long, and it is difficult to apply force, resulting in installation difficulties and low installation efficiency. Utility Model Content

[0003] The utility model aims to solve one of the problems existing in the existing related technologies to at least a certain extent. To this end, the utility model provides a long bolt that is easy to operate and screw.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] The utility model relates to a long bolt which is easy to operate and twist. The long bolt comprises a bolt body. A plurality of groups of slots for cooperating with a wrench are arranged on the bolt body at intervals along the axial direction thereof.

[0006] In some embodiments, the slot portion includes notches symmetrically arranged on the outer wall of the bolt body, and the wrench can be clamped between the two notches.

[0007] In some embodiments, the opening directions of the slots of two adjacent groups of slot portions are inconsistent.

[0008] In some embodiments, the plurality of slots are spirally arranged in sequence along the axial direction of the bolt body.

[0009] In some embodiments, both end corners of the bolt body are beveled.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] By arranging a plurality of groups of slots for cooperating with the wrench at intervals along the axial direction of the bolt body, the wrench can be as close as possible to the side of the workpiece cooperating with the bolt body during the installation or removal operation of the bolt body, which makes it easier to apply force to the wrench, thereby facilitating the installation or removal of the bolt and improving the efficiency of the bolt installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a three-dimensional schematic diagram of the bolt body of the utility model;

[0013] Figure 2 It is a schematic front view of the bolt body of the present invention. DETAILED DESCRIPTION

[0014] The following detailed description provides various embodiments or examples for implementing the present invention. These are, of course, merely examples and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. This repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the various embodiments and / or configurations discussed.

[0015] like Figure 1-Figure 2 The long bolt shown is easy to operate and twist, including a bolt body 1. The bolt body 1 includes a long rod with an external thread. There are no bolt heads at both ends of the long rod. Several groups of slots 2 for cooperating with a wrench are arranged at intervals along the axial direction of the bolt body 1. When the bolt body 1 is installed or removed, the wrench can be as close as possible to the side of the workpiece that cooperates with the bolt body, which is convenient for applying force to the wrench, thereby facilitating the installation or removal of the bolt and improving the efficiency of bolt installation.

[0016] Furthermore, the slot portion 2 includes slots 21 symmetrically arranged on the outer wall of the bolt body 1. The wrench can be clamped between the two slots 21. During the twisting operation, the wrench can be directly inserted into the two slots, so that the bolt body 1 can be twisted by the wrench. When processing the slot 21, the slot can be directly cut by a milling cutter on a milling machine, which is more convenient to process.

[0017] See also Figure 1-Figure 2 As shown, the opening directions of the slots 21 of two adjacent groups of slot portions 2 are inconsistent, so that there is a rotation angle A between the two adjacent slot portions 2.

[0018] Preferably, the rotation angle A is set to 90°, or several of the slot portions 2 are spirally arranged in sequence along the axial direction of the bolt body 1; during operation, when operating in a relatively narrow space, the operator uses a wrench to tighten the bolt body 1 at the same side. After the wrench drives the bolt body 1 to rotate a certain angle, there must be a group of slot portions 2 that are aligned with the operator's direction position, so that the operator does not need to move the position and can also clip the wrench into the slot portion 2, which is very convenient and can improve work efficiency.

[0019] It should be noted that the above-mentioned rotation angle A of 90° is only a preferred implementation method of this embodiment, but the present invention is not limited to the above implementation method. It can also be any angle of 30°, 60° and equal parts. As long as the technical effect of the present invention is achieved by any same or similar means, it should fall within the scope of protection of the present invention.

[0020] Furthermore, both end corners of the bolt body 1 are provided with bevels 81 , so as to facilitate the bolt body 1 to be screwed into the threaded hole.

[0021] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above in conjunction with the accompanying drawings. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
