Description

Technical Field

[0001] The utility model relates to the technical field of igniters, in particular to a thin-film bridge type igniter. Background Art

[0002] An igniter refers to a device that can provide sufficient energy in an instant to ignite pulverized coal, oil (gas) fuel and can stabilize the flame. The thin-film bridge type igniter is often used for blasting ignition.

[0003] There is a existing thin-film bridge type igniter (application number: 202022086335.3). By clamping the ignition button, without pulling the clamping button, the ignition button cannot be pressed, preventing ignition caused by workers accidentally touching the ignition button during construction, improving the safety of using the igniter, and also reducing property losses caused by accidental touching. However, the above still has the problem that when using the igniter, it is necessary for the staff to press the button of the igniter to achieve blasting ignition. Since the button of the igniter is always exposed outside, it is very easy for the button of the igniter to be damaged after being impacted and scratched by foreign objects, which is not convenient for the staff to protect the button of the igniter. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defect that it is not convenient for the staff to protect the button of the igniter in the prior art and it is very easy for the button of the igniter to be damaged, and to propose a thin-film bridge type igniter.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a thin-film bridge type igniter, including an igniter. One side of the top of the igniter is fixedly connected to the bottom of a vertical rod. The outer wall of the upper part of the vertical rod is rotationally connected to the inner wall of a cross block through a bearing. One end of the cross block is fixedly connected to the upper part of one side of a straight plate. One end of the straight plate is fixedly connected to one end of a cylinder body. A protection structure is arranged on one side of the cylinder body.

[0007] Preferably, the protection structure includes a threaded rod. One side of the outer wall of the threaded rod is threadedly connected to the inner wall of one end of the cylinder body. One end of the threaded rod is rotationally connected to a cross bar through a bearing. One side of the outer wall of the cross bar is in clearance fit with the inner wall of the lower part of the straight plate. One end of the outer wall of the cross bar is in clearance fit with the groove on one side of the upper part of the vertical rod. A shell is arranged on one side of the cross bar. One end of the shell is fixedly connected to the other end of the cross block. The bottom of the shell is in contact with the top of the igniter.

[0008] Preferably, vertical cylinders are fixedly connected to the four corners of the bottom of the igniter.

[0009] Preferably, a handle is fixedly connected to the top of the shell.

[0010] Preferably, a rubber sleeve is fixedly connected to the outer wall of the handle.

[0011] Preferably, a lead wire is installed at one end of the igniter.

[0012] The beneficial effect of a film bridge type igniter proposed by the present utility model lies in that: through the cooperation of the igniter, the lead wire, the vertical cylinder, the vertical rod, the horizontal block, the straight plate, the cylinder body, the handle, the rubber sleeve and the protection structure, when the device is in use, the handle can be rotated, the handle drives the shell to rotate, the shell drives the horizontal block to rotate, the horizontal block drives the straight plate to rotate, and the straight plate drives the cross bar to rotate. Furthermore, the shell shields and protects the button of the igniter. Rotate the threaded rod, and the threaded rod drives the cross bar to move to the right, so that the cross bar is inserted into the groove of the vertical rod, thereby realizing the positioning of the shell, facilitating the staff to protect the button of the igniter and preventing the button of the igniter from being damaged.

[0022] The protection structure 2 includes a threaded rod 2a1. One side of the outer wall of the threaded rod 2a1 is threadedly connected to the inner wall of one end of the cylinder 8. One end of the threaded rod 2a1 is rotatably connected to a cross bar 2a2 through a bearing. One side of the outer wall of the cross bar 2a2 is in clearance fit with the inner wall of the lower part of the straight plate 7. One end of the outer wall of the cross bar 2a2 is in clearance fit with the groove on one side of the upper part of the vertical rod 5. A housing 2a3 is provided on one side of the cross bar 2a2. One end of the housing 2a3 is fixedly connected to the other end of the cross block 6. The top of the housing 2a3 is fixedly connected to a handle 9. A rubber sleeve 10 is fixedly connected to the outer wall of the handle 9. The handle 9 facilitates the rotation of the housing 2a3. An opening is processed on the front end face of the housing 2a3. The bottom of the housing 2a3 is in contact with the top of the igniter 1. Rotate the handle 9, the handle 9 drives the housing 2a3 to rotate, the housing 2a3 drives the cross block 6 to rotate, the cross block 6 drives the straight plate 7 to rotate, and the straight plate 7 drives the cross bar 2a2 to rotate. Then the housing 2a3 shields and protects the button of the igniter 1. Rotate the threaded rod 2a1, the threaded rod 2a1 drives the cross bar 2a2 to move to the right, so that the cross bar 2a2 is inserted into the groove of the vertical rod 5, thereby realizing the positioning of the housing 2a3, facilitating the staff to protect the button of the igniter 1, and preventing the button of the igniter 1 from being damaged.
