Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aviation sealant construction, in particular to a special installation tool for rubber sealing caps of aviation fasteners. Background Art
[0002] One current method for sealing aircraft fasteners involves using pre-formed rubber sealing caps with sealant. These bowl-shaped caps are pre-formed with a suitable sealant. Upon installation, the caps are injected with sealant and then installed over the fasteners being sealed. The caps, along with the sealant, eventually solidify and remain attached to the aircraft. Current installation methods rely on manual installation. However, due to the varying sizes of the caps, smaller ones are particularly difficult to grasp. Furthermore, the caps themselves are relatively soft and easily deform during installation, resulting in uneven sealant overflow and making installation difficult. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Reference Figures 1 to 3The utility model provides a special installation tool for rubber sealing caps of aviation fasteners: comprising an operating handle 1, the bottom end of the operating handle 1 is fixedly connected to a simulated rubber cap body 2, a magnetic chip 101 is installed inside the operating handle 1, the simulated rubber cap body 2 is in the shape of an inverted bowl, the cross-section of the operating handle 1 is hexagonal, and the operating handle 1 adopts a thick standard hexagonal handle design, which can meet the needs of manual installation and can be matched with existing electric screwdrivers, standard hexagonal socket wrenches or hexagonal ratchet wrenches, and the top of the operating handle 1 is open;
[0025] The simulated rubber cap body 2 is composed of a first connector 201 and a second connector 202, and the first connector 201 and the second connector 202 are integrally formed. The second connector 202 is composed of a first arc segment 203, a vertical segment 204 and a second arc segment 205, and the first arc segment 203, the vertical segment 204 and the second arc segment 205 are integrally formed. The first arc segment 203 is connected to the bottom of the first connector 201, and a raised connecting segment 206 is provided on the inner wall of the connection between the first arc segment 203 and the first connector 201. The raised connecting segment 206 is integrally formed with the first arc segment 203 and the first connector 201, and the raised connecting segment 206 cooperates with the first arc segment 203 and the first connector 201, so that the interior of the simulated rubber cap body 2 has a non-slip design, which will not cause it to fall off when the rubber sealing cap is installed.
[0026] Working principle:
[0027] The internal shape of the simulated rubber cap body 2 is similar to the external shape of the rubber sealing cap. The design of the first connector 201 and the second connector 202 makes the internal of the simulated rubber cap body 2 anti-slip, so that the rubber sealing cap will not fall off when it is installed. The simulated rubber cap body 2 and the bottom of the rubber sealing cap are reserved for installation compression space (refer to Figure 3 ), which allows the internal sealant to be squeezed out evenly;
[0028] The rubber sealing cap is filled with sealant. When the simulated rubber cap body 2 is rotated with the rubber sealing cap for installation, the anti-slip design inside the simulated rubber cap body 2 can drive the rubber sealing cap to rotate, making the installation action smooth.
[0029] The operating handle 1 adopts a thick standard hexagonal handle design, which can meet the needs of manual installation and can be used with existing electric screwdrivers, standard hexagonal socket wrenches or hexagonal ratchet wrenches. The operating handle 1 is wrapped with a magnetic chip 101, which can be attracted to tools with hexagonal sockets and will not fall off during construction. The product can be classified by different colors for different models, which is easy for users to identify. When using the installation tool to install the rubber sealing cap, the work efficiency is improved. The rubber sealing cap can be easily installed to a position that cannot be reached by hands with the help of the installation tool; and the sealant can be evenly overflowed during installation, thereby achieving a sealing effect of continuous overflow of the glue layer and reducing rework.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
