Description

Technical Field

[0001] The utility model relates to the technical field of industrial detonating equipment, in particular to a protective rubber plug used for detonating equipment. Background Art

[0002] In the blasting industry, general detonating equipment is used more and more widely. However, in actual industrial sites, detonating equipment works in harsh environments with accumulated dust for a long time. Currently, protective rubber plugs are usually used to protect the data interface to ensure the normal operation of the detonating equipment.

[0003] Patent document CN202424805U proposes a USB plug structure for a mobile phone, which uses a USB plug handle to fix the mobile phone plug to the product. However, the disadvantage is that the USB plug handle takes up a lot of product space, resulting in a waste of product design space.

[0004] Patent document CN203872214U proposes a dustproof rubber plug for a mobile phone USB interface, one end of which is fixed to the side wall of the mobile phone by a fastener, and the other end is provided with a handle. However, the disadvantage is that the rubber plug needs two hands to be opened. If one hand is released, the rubber plug will return to a closed state due to the elastic arm. In the case where the product itself is heavy and large in size (such as an industrial mobile phone), it is not easy to open the rubber plug and insert the connector when working outdoors, and it is difficult to achieve single-handed operation.

[0005] In summary, the existing protective rubber plugs are not easy to operate with one hand and will cause a waste of design space. In addition, the existing protective rubber plugs only meet the protection of one data interface. If the device has two data interfaces, it is even more difficult to operate with one hand and it is impossible to achieve protection at the same time. Utility Model Content

[0006] In view of the above problems, the utility model provides a protective rubber plug for an initiating device, which is easy to operate and can be operated with one hand, and can avoid wasting design space and meet the protection requirements of multiple data interfaces.

[0008] Furthermore, both left and right ends of the middle rubber plug are provided with assembly grooves, so that the middle rubber plug is in an I-shape as a whole, and a first slot hole is opened on the side wall of the assembly groove;

[0009] Furthermore, the side ends of the left rubber plug and the right rubber plug are each provided with a first protrusion corresponding to the assembly groove, the first protrusion is provided with a second slot hole, and the left rubber plug, the middle rubber plug and the right rubber plug are rotatably connected to each other through the cooperation of the latch steel rod and the first slot hole and the second slot hole;

[0010] Furthermore, the left rubber plug, the middle rubber plug and the right rubber plug are all made of 85-degree Shore silica gel; the fasteners are made of carbon steel screws; the bolt steel rod is made of SUS304;

[0011] Furthermore, the inner diameters of the first slot hole and the second slot hole are not greater than the diameter of the bolt steel rod, and the length of the bolt steel rod is not greater than the width of the left rubber plug and the right rubber plug;

[0012] Furthermore, the surfaces of the left rubber plug and the right rubber plug at the buckling end are both provided with a second protrusion, and the buckling ends of the left rubber plug and the right rubber plug are both provided with a groove;

[0013] Furthermore, a third protrusion is provided on the left rubber plug and / or the right rubber plug, and the third protrusion matches the data interface and extends into the data interface.

[0014] The beneficial effect of the utility model is that the rubber plug body is divided into a three-section structure of a left rubber plug, a middle rubber plug and a right rubber plug. After the rubber plug body is assembled on the detonating device, the left rubber plug and the right rubber plug can be turned and snapped together with one hand, which is simple and convenient to operate and can avoid wasting design space. The left rubber plug and the right rubber plug can meet the protection of two data interfaces. At the same time, the structure is reliable and not easy to fall off, and has good use value.
