Description

Technical Field

[0001] This application belongs to the field of ground strength test loading technology, and specifically relates to a compact adhesive tape and lever connector. Background Technology

[0002] In ground verification tests of aircraft structural strength, the tape-lever system loading method is a commonly used loading method, and the connector between the tape and the lever is an essential component in this loading method.

[0003] Currently, the connection between the adhesive tape and the lever is achieved using either a fixed-length steel wire rope or a steel wire rope with a threaded pull plate. Because the steel wire rope and threaded pull plate are relatively long, the distance between the adhesive tape and the lever is significant, resulting in a corresponding increase in the overall height of the adhesive tape-lever system. This makes it impossible to support the overall height of the adhesive tape-lever system in certain confined spaces, thus limiting the use of this loading method.

[0004] Therefore, a more compact connector is needed to shorten the distance between the tape and the lever, thereby reducing the overall height of the loading system for installation of tape-lever loading systems in confined spaces. Summary of the Invention

[0005] The purpose of this application is to provide a compact connector for adhesive tape and lever to solve the problem of excessive overall height in existing adhesive tape-lever systems.

[0006] The technical solution of this application is: a compact adhesive tape and lever connector, including a fixing collar, a single-ear screw and a nut; the fixing collar has symmetrically arranged double circular holes on both sides, a threaded hole in the middle of the fixing collar, the single-ear screw is vertically threaded into the threaded hole, and the nut is threaded to the end of the single-ear screw.

[0007] Preferably, a rectangular boss is provided in the middle of the fixing collar, and the threaded hole is provided in the boss.

[0008] Preferably, the single-ear screw includes a stud and a single-ear ring integrally formed with the stud, the single-ear ring being capable of connecting a lever.

[0009] The compact tape and lever connector of this application, during operation, involves inserting an aluminum rod from the tape into a fixing collar to connect the connector to the tape, and then connecting the lever to the single-ear screw with bolts to complete the connection between the tape and the lever.

[0010] By using this connector, the overall height of the tape and lever system is significantly reduced. This allows for the installation of the tape-lever system in confined spaces, greatly expanding the application range of the tape-lever loading system. Attached Figure Description

[0011] To more clearly illustrate the technical solutions provided in this application, the accompanying drawings will be briefly described below. Obviously, the drawings described below are merely some embodiments of this application.

[0012] Figure 1 This is a structural diagram of the connection between the lever system and the adhesive tape in this application;

[0013] Figure 2 This is a schematic diagram of the overall structure of the connector in this application.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] A compact adhesive tape and lever connector, such as Figure 1 Existing adhesive tape and lever systems, such as Figure 1 As shown, the connector is located between the adhesive tape and the lever system. The adhesive tape is wrapped around the aluminum rod in a loop manner to form two sets. The two sets of aluminum rods are symmetrically arranged through the connector. The lever is located directly above the two sets of aluminum rods. The middle position of the lever is located at the opening for connection. It can be effectively connected and fixed to the connector by means of bolts or pins.

[0017] like Figure 2 The assembly includes a retaining collar 1, a single-ear screw 2, and a nut 3. The retaining collar 1 has symmetrically arranged double circular holes on both sides, and a threaded hole in the middle. The single-ear screw 2 is vertically threaded into the threaded hole, and the nut 3 is threaded to the end of the single-ear screw 2. During operation, the aluminum rod on the adhesive tape is inserted into the retaining collar 1, connecting the connector to the adhesive tape. Then, the lever is bolted to the single-ear screw 2, completing the connection between the adhesive tape and the lever.

[0018] By using this connector, the overall height of the tape and lever system is significantly reduced. This allows for installation of the tape-lever system in confined spaces, greatly expanding its application range. Disassembly is simple and convenient; simply unscrew nut 3 and remove the one-way screw from the threaded hole to separate the components.

[0019] Preferably, a rectangular boss is provided in the middle of the fixing collar 1, and a threaded hole is provided in the boss. The design of the boss makes the fixing collar 1 and the single-ear screw 2 fit stably.

[0020] Preferably, the single-ear screw 2 includes a stud and a single-ear ring integrally formed with the stud. The single-ear ring can connect to the lever. The single-ear screw 2 can further simplify the structure through a bidirectional connection combination structure.

[0021] In summary, this application has the following advantages:

[0022] 1. It greatly shortens the distance between the lever and the tape;

[0023] 2. The compact connector design is simple, easy to operate, and easy to use and install;

[0024] 3. It can still be used in limited spaces, thus expanding its scope of application.

[0025] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this invention only involve the structures involved in the embodiments disclosed in this invention. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other.

[0026] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
