DETAILED DESCRIPTION

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0019] Please refer to Figures 1-4 , the utility model provides an embodiment: a kind of connecting device for building heating and ventilation pipeline of convenient fixing type, including first clamping plate 1, mounting plate 2, second clamping plate 9, first installation block 12 and second installation block 17, the bottom of mounting plate 2 one end is installed with first clamping plate 1, and the bottom of mounting plate 2 is installed with fixed nut 8 away from the end of first clamping plate 1, fixed nut 8 is internally threaded with fixed bolt 7, the end of fixed bolt 7 away from first clamping plate 1 is installed with handle, and the outside of handle is installed with sponge cover, to facilitate staff to rotate fixed bolt 7, the bottom of mounting plate 2 is close to the end of fixed nut 8 and is provided with sliding groove 3, and sliding groove 3 is internally slidably installed with sliding block 4, the bottom of sliding block 4 is installed with second clamping plate 9, and the bottom of second clamping plate 9 is installed with second installation block 17, the bottom of first clamping plate 1 is installed with first installation block 12.

[0020] As Figure 1 Shown, the top of second clamping plate 9 close to the end of fixed nut 8 is installed with bearing 5, and the inside of bearing 5 is installed with connecting rotating rod 6, the end of connecting rotating rod 6 away from bearing 5 is connected with fixed bolt 7, when using, by rotating fixed bolt 7, so that fixed bolt 7 drives second clamping plate 9 to move through bearing 5 and connecting rotating rod 6, i. e. second clamping plate 9 can be directly clamped and fixed with the outside of heating and ventilation pipeline, two groups of heating and ventilation pipeline can be directly clamped and fixed, and the operation is relatively convenient during fixing process, and the device is relatively convenient to use.

[0021] As Figures 1-4As shown, the bottom of the first mounting block 12 is provided with a fixed clamping groove 11, and the end of the first mounting block 12 close to the second clamping plate 9 is provided with a mounting slot 16, which is in communication with the fixed clamping groove 11. The end of the second mounting block 17 close to the first clamping plate 1 is provided with a mounting plug 15, the bottom of the mounting plug 15 is provided with a mounting groove 13, and the top of the inside of the mounting groove 13 is provided with a fixed spring 14. The bottom of the fixed spring 14 is provided with a fixed clamping block 10, and the outer side of the fixed spring 14 is provided with an anti-rust layer. When the first clamping plate 1 and the second clamping plate 9 are attached to the outside of the heating and ventilation pipeline, the mounting plug 15 is inserted into the inside of the mounting slot 16, and the fixed clamping block 10 is clamped into the inside of the fixed clamping groove 11, so that the first clamping plate 1 and the second clamping plate 9 are fixed firmly. During use, even if the fixed bolt 7 is loose due to rust or thread slipping, the first clamping plate 1 and the second clamping plate 9 can still be firmly installed on the outside of the heating and ventilation pipeline, having a double fixing effect, preventing the heating and ventilation pipeline from falling off between the first clamping plate 1 and the second clamping plate 9, and effectively improving the stability of the device.

[0022] Working principle:

[0023] When installing, place the two groups of heating and ventilation pipelines between the first clamping plate 1 and the second clamping plate 9, and attach the pipe openings of the two groups of heating and ventilation pipelines, so that the two groups of heating and ventilation pipelines are connected;

[0024] The worker can rotate the fixed bolt 7 clockwise, the fixed bolt 7 drives the connecting rotating rod 6 to rotate, the connecting rotating rod 6 rotates in the inside of the bearing 5, and the bearing 5 does not drive the second clamping plate 9 to rotate through the bearing 5;

[0025] The fixed bolt 7 moves in the inside of the fixed nut 8 through the thread, and the fixed bolt 7 drives the second clamping plate 9 to move together through the connecting rotating rod 6 and the bearing 5, so that the first clamping plate 1 and the second clamping plate 9 are tightly attached to the outside of the two groups of heating and ventilation pipelines, the two groups of heating and ventilation pipelines are clamped firmly through the first clamping plate 1 and the second clamping plate 9, and the gap at the connection position of the two groups of heating and ventilation pipelines is shielded by the first clamping plate 1 and the second clamping plate 9;

[0026] When the first clamping plate 1 and the second clamping plate 9 are tightly attached to the outside of the two groups of heating and ventilation pipelines, the first clamping plate 1 and the second clamping plate 9 are closed, at this time, the second mounting block 17 is attached to the first mounting block 12, so that the mounting plug 15 on the second mounting block 17 is inserted into the inside of the mounting slot 16;

[0027] When the fixing clamping block 10 at the bottom of the installation plug 15 moves to the position directly opposite the fixing clamping groove 11, the elastic action of the fixing spring 14 pushes the fixing clamping block 10, and the fixing clamping block 10 can be clamped into the inside of the fixing clamping groove 11. The installation plug 15 is limited by the fixing spring 14, and the installation plug 15 and the second installation block 17 cannot continue to move, the first installation block 12 and the second installation block 17 can be installed firmly, and thus the first clamping plate 1 and the second clamping plate 9 can be installed firmly.

[0028] During use, even if the fixing bolt 7 is loose due to rust or thread slipping, the first clamping plate 1 and the second clamping plate 9 can still be installed firmly on the outside of the heating and ventilation pipeline by fixing the first installation block 12 and the second installation block 17, and the device has a double fixing effect, can prevent the heating and ventilation pipeline from falling off between the first clamping plate 1 and the second clamping plate 9, and can effectively improve the stability of the device.

[0029] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as exemplary and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and thus all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.
