[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.
[0023] like Figure 1 The diagram shows the structure of an electronic lock, including an electronic lock body 1. One end of the electronic lock body 1 is equipped with a quick-release body 5. A 90-degree unlocking elbow 3 is connected to the electronic lock body 1. One end of the 90-degree unlocking elbow 3 is connected to the quick-release body 5, and the other end is connected to the unlocking pull rope sleeve 4. The 90-degree unlocking elbow 3 has an opening. A pull rope is installed inside the unlocking pull rope sleeve 4. The pull rope passes through the opening and is connected to the electronic lock body 1. The opening on the 90-degree unlocking elbow 3 is equipped with a protective structure to prevent water from splashing into the pull rope and freezing it.
[0024] like Figure 1 As shown, the 90-degree unlocking elbow 3 is connected to the quick-release body 5 and secured by the quick-release clip 2. After the 90-degree unlocking elbow 3 is connected to the quick-release body 5, installation is completed by securing it with the quick-release clip 2; the installation method is convenient and quick. The 90-degree unlocking elbow 3 can rotate at any angle around the central axis of the quick-release body 5.
[0025] like Figures 2-4 As shown, the protective structure consists of a plug 6 and a resin-filled layer 7. The plug 6 is inserted into the opening on the 90-degree unlocking elbow 3, forming a pre-drilled hole 9 for the rope. Resin is injected into the plug 6 using a resin-filling device to form the resin-filled layer 7, thus fixing the plug 6 to the opening on the 90-degree unlocking elbow 3. This protective structure adds a shielding block to the original elbow body and then injects resin to improve the protection level. The pull rope passes through the pre-drilled hole 9, effectively preventing water from splashing into the pull rope and freezing it.
[0026] like Figures 5-8As shown, the protective structure is a bend cover 8 fixedly connected to the opening position of the 90-degree unlocking elbow 3. The front of the bend cover 8 is smooth and flat, and the back has a raised rib 10 that engages with the opening position on the 90-degree unlocking elbow 3. After the bend cover 8 is closed onto the 90-degree unlocking elbow 3, a pre-reserved through hole 9 for hanging rope is formed in the opening position. A ring of welding rib structure 11 for connecting the bend cover 8 is provided at the opening position on the 90-degree unlocking elbow 3. The inner side of the welding rib structure 11 has an inner overflow groove 12, and the outer side has an outer overflow groove 13. The overall structure is connected by welding, using ultrasonic welding or laser welding. The welding joint is equipped with welding ribs and overflow grooves to meet welding requirements. The advantage of this structure is that the process is simple and stable, and it is suitable for mass production.
[0027] like Figure 9 As shown, the protective structure is an aluminum tube 14 fixedly connected to the opening position on the 90-degree unlocking elbow 3. The aluminum tube 14 and the 90-degree unlocking elbow 3 are integrally injection molded with rubber coating, and a pre-reserved through hole 9 for hanging rope is formed inside the aluminum tube 14. Because the precision of the mold is higher than that of the metal hose, to protect the mold and reduce problems such as poor unlocking pull caused by rust and corrosion of the metal hose, the aluminum tube was ultimately chosen as the base material after experimentation. The aluminum tube is placed in the mold and integrally injection molded. The integral molding of the mold results in high product stability; the aluminum tube base material provides higher overall product strength.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
