Abstract
An object of the utility model is to provide a bolt device that fast fastening loosened for realize two plate quick assembly disassembly's technical problem. A bolt device capable of being fastened and loosened quickly comprises a first connecting piece and a second connecting piece, wherein an operation cavity allowing a bolt assembly to be disassembled and assembled is formed in the first connecting piece and the second connecting piece; the first platform hole and the second platform hole are correspondingly arranged; the end part of the first platform hole is provided with a step groove.
Description
Technical Field
The utility model belongs to the technical field of the bolt-up device technique and specifically relates to a bolt device that fastening loosens fast.
Background
In the field of machine manufacturing, various plates are connected, and particularly in the occasions of tools needing frequent disassembly and assembly, the disassembly and assembly of workpieces are time-consuming. When two plate members are bolted together, the common method is to perforate, thread the bolt and then tighten the bolt with a nut. In this way, the following disadvantages exist: the bolt assemblies need to be screwed one by one, and the bolt assemblies need to be unscrewed one by one during disassembly, which wastes time and labor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bolt device that fast fastening loosened for realize two plate quick assembly disassembly's technical problem.
The utility model provides a technical scheme that its technical problem adopted is:
a bolt device capable of being fastened and loosened quickly comprises a first connecting piece and a second connecting piece, wherein an operation cavity allowing a bolt assembly to be disassembled and assembled is formed in the first connecting piece and the second connecting piece; the first platform hole and the second platform hole are correspondingly arranged; the end part of the first platform hole is provided with a step groove.
Preferably, the first and second wells are semi-open.
Preferably, the sum of the lengths of the first hole and the second hole is smaller than the length of the bolt rod in the mounted bolt assembly.
The effects provided in the contents of the present invention are only the effects of the embodiments, not all the effects of the present invention, and the above technical solutions have the following advantages or beneficial effects:
in the technical scheme, the quick assembly and disassembly between the two plates can be conveniently realized.
Drawings
FIG. 1 is a diagram illustrating the overall structure of an embodiment of the present invention;
FIG. 2 is a partial enlarged view of an embodiment of the present invention;
fig. 3 is another enlarged view of a portion of an embodiment of the present invention;
in the figure: 1. a first connecting member; 2. a second connecting member; 3. an operating chamber; 4. a first hole; 5. a second hole; 6. a step groove.
Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and techniques are omitted so as to not unnecessarily limit the invention.
As shown in fig. 1 to 3, a quick fastening and loosening bolt device includes a first connecting member 1 and a second connecting member 2, and the first connecting member 1 and the second connecting member 2 are illustrated as circular ring members for clarity of presentation in this embodiment. An operation cavity 3 allowing the bolt assembly to be assembled and disassembled is arranged in the first connecting piece 1 and the second connecting piece 2. A plurality of first holes 4 are formed in the first connecting piece 1, a second hole 5 is formed in the second connecting piece 2, and the first holes 4 and the second holes 5 are correspondingly arranged and used for installing bolt rods in the bolt assembly; preferably, the first and second wells 4 and 5 are semi-open. The end of the first hole 4 is provided with a step groove 6, and after the bolt assembly is installed, the step groove 6 is used for clamping and fixing a bolt head.
The utility model discloses a use method does: the first connecting piece 1 and the second connecting piece 2 are butted together, and the first hole 4 and the second hole 5 are aligned; the bolt, the flat washer and the nut are assembled together into a bolt group, and the distance from the flat washer to the bolt head is adjusted to be slightly larger than the sum of the thicknesses of the first connecting member 1 and the second connecting member 2 by a pitch of 1-2 turns (about 2 mm). The bolt is placed into the first platform hole 4 and the second platform hole 5 through the side, the parallel surfaces on the two sides of the bolt head are clamped into the step groove 6, and the first connecting piece 1 and the second connecting piece 2 can be connected and fastened by screwing the nut.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
Although the specific embodiments of the present invention have been described with reference to the drawings, the present invention is not limited thereto, and various modifications or variations that can be made by those skilled in the art without inventive labor are still within the scope of the present invention.
