Abstract
The utility model provides a clamp type hole protection connecting device which comprises a first hoop plate, a second hoop plate, two connecting long rods and a fixed steel plate, wherein one ends of the two connecting long rods are fixedly provided with external thread sections, one ends of the two external thread sections are respectively provided with a manual adjusting cap in a threaded manner, the surface of the fixed steel plate is provided with a round hole site and a strip hole site, and the round hole site and the strip hole site are respectively connected with the two connecting long rods in an assembling manner. According to the utility model, the round hole site and the strip-shaped hole site are formed in the fixed steel plate, so that the fixed steel plate is changed from a simple support structure with two fixed points into a hinge structure with one fixed end and one free end, and when the fixed steel plate is assembled and disassembled, only a plurality of screw rings are needed to be tightened or loosened, and then the fixed steel plate is rotated, so that the connecting device can be taken down, and the assembly and disassembly efficiency is greatly improved; meanwhile, the manual adjusting cap does not need to be screwed on the tail part of the external thread section during assembly and disassembly, and the loss rate of the manual adjusting cap is greatly reduced in the actual construction process.
Description
Technical Field
The utility model belongs to the technical field of opening protection accessories, and relates to a clamp type opening protection connecting device.
Background
During the course of the new portal protection connector experiments, we have found a small optimization of the old portal protection connector (i.e., double clasps).
In order to increase the universality, the double hoops are suitable for a large range of wall thickness, and long screw rods (shown in fig. 3) are adopted, however, in the practical use process, the long screw rods bring trouble to the installation and the disassembly, too many threads are needed for the complete withdrawal of the screw cap, tens of circles are needed for the tightening, tens of circles are needed for the installation and the disassembly processes, and the electric wrench cannot be used, so that the construction efficiency is greatly influenced.
Disclosure of Invention
The utility model aims to provide a clamp type hole protection connecting device, which is used for solving the problems in the background technology.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a fixture formula entrance to a cave protection connecting device, includes first staple bolt board, second staple bolt board, two connection stock and fixed steel sheet, the front and the one end welded connection of two connection stock of first staple bolt board, the front fixed mounting of second staple bolt board has two symmetrical pole cover bodies, two the pole cover body alternates with the connection stock that corresponds to be connected, two the one end fixed mounting of connection stock has the external screw thread section, two the equal screw thread of one end of external screw thread section installs manual regulation cap, a round hole site and a bar hole site have been seted up to the surface of fixed steel sheet, round hole site and bar hole site are respectively with two connection stock assembly connections.
In the fixture type hole protection connecting device, the limiting rubber plug is movably arranged in the strip-shaped hole site.
Compared with the prior art, the fixture type hole protection connecting device has the advantages that: the fixing steel plate is provided with a round hole site and a strip hole site, so that the fixing steel plate is changed from a simple support structure with two fixed points into a hinge structure with one fixed end and one free end, and when the fixing steel plate is assembled and disassembled, only a plurality of screw rings are needed to be tightened or loosened, and then the fixing steel plate is rotated, so that the connecting device can be taken down, and the assembling and disassembling efficiency is greatly improved; meanwhile, the manual adjusting cap does not need to be screwed on the tail part of the external thread section during assembly and disassembly, and the loss rate of the manual adjusting cap is greatly reduced in the actual construction process.

Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1, fig. 2 and fig. 3, the clamp type hole protection connecting device comprises a first hoop plate 1, a second hoop plate 2, two connecting long rods 3 and a fixed steel plate 7, wherein the front surface of the first hoop plate 1 is welded with one ends of the two connecting long rods 3, two symmetrical penetrating rod sleeves 4 are fixedly arranged on the front surface of the second hoop plate 2, the two penetrating rod sleeves 4 are connected with the corresponding connecting long rods 3 in a penetrating way, an external thread section 5 is fixedly arranged at one end of the two connecting long rods 3, manual adjusting caps 6 are arranged at one ends of the two external thread sections 5 in a threaded way, a round hole position 9 and a strip-shaped hole position 10 are formed in the surface of the fixed steel plate 7, the round hole position 9 and the strip-shaped hole position 10 are respectively connected with the two connecting long rods 3 in an assembling way, and a limiting rubber plug 8 is movably arranged in the strip-shaped hole position 10.
According to the utility model, the fixed steel plate 7 is provided with the round hole position 9 and the strip-shaped hole position 10, so that the fixed steel plate 7 is changed from a simple support structure with two fixed points into a hinge structure with one fixed end and one free end, and when the connecting device is assembled and disassembled, only a few screw rings are needed to be tightened or loosened, and then the fixed steel plate is rotated, so that the connecting device can be taken down, and the assembling and disassembling efficiency is greatly improved; meanwhile, the manual adjusting cap 6 does not need to be screwed on the tail part of the external thread section 5 during assembly and disassembly, and in the actual construction process, the loss rate of the manual adjusting cap 6 is greatly reduced, more importantly, the materials are not increased, the extra cost is avoided, and the existing stock products can be optimized uniformly for one time.
What is not described in detail in this specification is prior art known to those skilled in the art. The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
