Locking mechanism for electronic lead seal

[0016] The following describes the specific structure of the present invention in conjunction with the accompanying drawings of the specification:

[0017] A locking mechanism for electronic seals, such as figure 1 with figure 2 As shown, it includes a housing 1 with a sealing hole 11 for the sealing line 3 to pass through, and a locking mechanism is provided in the housing for locking the sealing line 3 in In the lead sealing hole 11, a gap 12 is provided in the middle of the lead sealing hole 11, and the locking mechanism includes a locking piece 4 for pressing the sealing line 3 and providing a locking elastic force for the locking piece 4 The elastic member 5, the locking piece 4 is rotatably installed inside the housing 1 through a connecting shaft, and the free end of the locking piece 4 extends into the notch 12 under the action of the elastic member 5 The lead seal hole 11. When the above-mentioned electronic seal is installed, the free end of the seal line 3 is inserted into the seal hole 11 after bypassing the object to be locked. During the insertion process, the end of the seal line 3 causes the locking piece 4 The force causes the locking piece 4 to overcome the force of the elastic component 5 and rotate. When the seal line 3 is inserted in place, the elastic component 5 exerts a locking elastic force on the locking piece 4 to press and lock the seal line 3. Prevent the sealing line 3 from exiting from the sealing hole.

[0018] In this embodiment, the elastic member 5 is a spiral compression spring, one end of the compression spring abuts on the locking piece 4, and the other end abuts on the compression spring positioning seat 13 in the housing 1 As a deformation, the elastic member 5 can also be a torsion spring in actual operation.

[0019] In this embodiment, the compression spring positioning seat 13 is formed with a first positioning structure for positioning one end of the compression spring, and the locking piece 4 is formed with a second positioning structure for positioning the other end of the compression spring. Specifically, the first positioning structure is a positioning groove 131, and the second positioning structure is a positioning boss 41. Through the positioning groove 131 and the positioning boss 41, one end of the compression spring is located in the positioning groove 131, and the other end is sleeved on the positioning boss 41, so that the compression spring can play a good role. Positioning function to ensure the effectiveness and stability of the installation and use of the compression spring.

[0020] As a further improvement, the lead sealing hole 11 is a through hole penetrating through the housing 1, and the end of the through hole has a bell mouth whose diameter gradually decreases from outside to inside. 11. Improve the convenience of threading operation. Specifically, the through hole is formed by sequentially connecting a first flared section 111, a cylindrical hole section 112, and a second flared section 113, the gap 12 is provided in the middle of the cylindrical hole section 112, and the cylindrical hole section The ratio of the length of 112 to the total length of the through hole is 1:6-7.

[0021] Obviously, the above-mentioned embodiments of the present invention are merely examples to clearly illustrate the present invention, and are not intended to limit the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. There is no need and cannot give an exhaustive list of all implementation methods. And these obvious changes or variations derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
