DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0028] like Figure 1-6As shown, the embodiment of the present application discloses a waterproof electronic lock emergency unlocking pull rope structure, including a sleeve 10, an emergency unlocking pull rope 20, a protective sleeve 30, a through-hole sleeve 11 and a fixed buckle 14. The sleeve 10 is fixedly arranged in the vehicle body through the through-hole sleeve 11 and the fixed buckle 14. The emergency unlocking pull rope 20 is arranged in the sleeve 10, one end of which is connected to the unlocking handle of the electronic lock, and the other end thereof passes through the sleeve 10 and extends to the dry area of the vehicle body. The end located in the dry area is crimped into a rope loop with a crimping sleeve, which is convenient for fingers to pull. A protective sleeve can be put on the rope loop to prevent the hand from being strangled due to the rope loop being too thin, affecting the user experience. The protective sleeve 30 is arranged on the emergency unlocking pull rope 20 between the unlocking handle of the electronic lock and the connecting sleeve 40, one end of which is sealed and fixed on the emergency unlocking pull rope 20, and the other end is sealed and connected to the end of the sleeve 10, so that water flows along the emergency unlocking pull rope 20 to the protective sleeve 30, and will not flow from the wet area to the dry area along the emergency unlocking pull rope 20. The protective cover 30 is retractable, so that even when the emergency unlocking pull rope 20 is pulled, the protective cover 30 can always maintain the sealing state of the emergency unlocking pull rope 20 and the sleeve 10.
[0029] The protective sleeve 30 is in the shape of a gourd as a whole, and the diameter of its small end is smaller than the diameter of the emergency unlocking pull rope 20, so that the small end and the emergency unlocking pull rope 20 are interference fit, thereby ensuring that the small end and the emergency unlocking pull rope 20 are tightly connected and well sealed. The large end of the protective sleeve 30 is in the shape of a straight tube and is provided with an external convex rib at the end. The outer wall of the straight section and the external convex rib form an annular groove 31, and a clamping groove is provided on the inner wall of the straight section away from the end. A connecting sleeve 40 is sleeved on one end of the sleeve 10 near the protective sleeve 30, and two annular convex ribs 41 are arranged at intervals on the connecting sleeve 40. The two annular convex ribs 41 and the outer wall of the connecting sleeve 40 form an annular installation groove. The outer wall of the connecting sleeve 40 near one end of the protective sleeve 30 is set in an inner eight-shaped shape, which is convenient for the connecting sleeve 40 to be inserted into the protective sleeve 30 and plays a guiding role. During installation, the connecting sleeve 40 is inserted into the protective sleeve 30 until the annular convex rib 41 on the connecting sleeve 40 away from the protective sleeve 30 touches the outer convex rib of the protective sleeve 30. At this time, the annular convex rib 41 of the connecting sleeve 40 adjacent to the protective sleeve 30 is just placed in the clamping groove of the protective sleeve 30, and the straight section of the protective sleeve 30 is sleeved in the annular installation groove. Then tie the cable tie 32 on the annular groove 31 to completely fix the protective sleeve 30 and the connecting sleeve 40. The protective sleeve 30 is made of rubber material and has good sealing after being completely fixed with the connecting sleeve 40. When specifically set, the outer wall of the gourd-shaped tube is a wavy structure, so that it is difficult for water on the pull rope to flow along the protective sleeve 30 to the sleeve 10. A fixing groove 42 is also provided at one end of the connecting sleeve 40 away from the protective sleeve 30, and a fir-shaped cable tie 43 for connecting with the vehicle body is provided on the fixing groove 42. The connecting sleeve 40 is connected to the sleeve 10 on the vehicle body through the fir-shaped cable tie 43.
[0030] The through hole sleeve 11 is truncated cone-shaped as a whole, and is provided with a sheet metal snap-in groove for snap-connecting with the vehicle body. A receiving hole 12 is provided in the through hole sleeve 11, and a sealing ring 13 is provided in the receiving hole 12. The sleeve 10 passes through the receiving hole 12 and its outer wall is sealed with the sealing ring 13 to prevent water from flowing from the outer wall of the sleeve 10 from the wet area to the dry area. The fixing buckle 14 is provided at one end of the sleeve 10 away from the protective sleeve 30, and is used to fix with the vehicle body. A through hole is provided in the fixing buckle 14 for the emergency unlocking pull rope 20 to pass through. The aperture of the through hole is slightly larger than the diameter of the emergency unlocking pull rope 20, so that after the emergency unlocking pull rope 20 passes through the through hole, it will not affect the smoothness of stretching, and it can also prevent debris from entering the through hole and causing the pull rope to be stuck and unable to be pulled.
[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
