[0017] In the description of the utility model, it is necessary to explain that, for the direction word, if the term "center", "transverse (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawings, only for the convenience of narrating the utility model and simplifying the description, and not indicating or implying that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the utility model.

[0018] In addition, if the terms "first", "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. Therefore, the "first", "second" features can be explicitly or implicitly included one or more features, and in the description of the utility model, the meaning of "several", "several" is two or more than two, unless otherwise explicitly specified.

[0019] Referring to Figures 1 to 5 Further illustrate the utility model.

[0020] A pull tab lock, including shell 1 and base 2, be provided with combination lock mechanism 14 and lock bar 3 on the base 2, the lock bar 3 is slidably connected with base 2, the lock bar 3 is provided with lock hook 4 and the elastic sheet 5 with elastic body, the elastic sheet 5 includes splicing part 6, inclined part 7 and horizontal part 8, and the included angle between splicing part 6 and horizontal part 8 extension surface in the relaxed state of elastic sheet 5 is acute angle, the lock bar 3 is provided with through slot 9, the lock hook 4 is located on the upper surface of lock bar 3, the lower bottom surface of lock bar 3 is provided with stop lever 10, the stop lever 10 is located on the side of lock hook 4 towards the unlocking direction, the splicing part 6 is provided with inclined clamping part 11, the clamping part 11 is inclined away from the lower bottom surface of lock bar 3, the clamping part 11 is located on the side of stop lever 10 towards the unlocking direction, the upper surface of splicing part 6 is in contact with the lower surface of lock bar 3, and the lower surface of splicing part 6 is in contact with the upper side of stop lever 10.

[0021] As Figures 1 to 5As shown, when installing the spring piece 5, the insertion part 6 is inserted into the through groove 9 from the locking side of the locking hook 4, and then passes under the locking hook 4 to the through groove 9 on the unlocking side. Then, the end of the insertion part 6 passes over the stop bar 10, and until its locking part 11 also passes over the stop bar 10, the end of the insertion part 6 contacts the lower surface of the locking bar 3. Finally, the insertion part 6 is elastically bent by the bottom of the locking hook 4, the upper side of the stop bar 10 and the lower surface of the locking bar 3, so as to realize the insertion of the spring piece 5. The insertion process is convenient and quick, improving the installation efficiency of the spring piece 5. The locking part 11 prevents the spring piece 5 from falling out, avoiding affecting its use.

[0022] Specifically, after the spring 5 is installed, the inclined part 7 tilts downward under the pressure of the locking hook 4, thereby making the horizontal part 8 horizontal.

[0023] like Figure 3 As shown, in this preferred embodiment, an inclined surface 12 is provided on the lower surface of the locking rod 3 to form an inclined groove. The inclined groove is connected to the through groove 9 and is located on the side of the through groove 9 facing the unlocking direction. The inclined surface 12 of the plug-in part 6 is in contact with it.

[0024] Specifically, when the plug part 6 is plugged in, it will bend in an arc shape and fit against the inclined surface 12 due to the obstruction of the bottom of the locking hook 4, the upper side of the stop bar 10 and the lower surface of the locking bar 3. The inclined surface 12 can reduce the degree of bending of the part of the plug part 6 in contact with the locking bar 3, thereby reducing the bending resistance during plugging and making plugging more convenient.

[0025] like Figure 3 As shown in this example, preferably, a limiting rod 13 is provided on the lower surface of the locking rod 3. The limiting rod 13 is located on one side of the inclined surface 12. The end of the insertion part 6 contacts the limiting rod 13, and the insertion length of the insertion part 6 is limited by the limiting rod 13.

[0026] like Figure 5 As shown, in this example, preferably, the upper side of the stop bar 10 is an arc-shaped end to reduce the force on the insertion part 6 when it bends.

[0027] like Figure 4 As shown, in this example, preferably, the snap-fit ​​portion 11 is located on one side of the insertion portion 6, which facilitates the forming of the snap-fit ​​portion 11. That is, the snap-fit ​​portion 11 can be formed by stamping on one side of the insertion portion 6.

[0028] Specifically, the base 2 is provided with a first mounting groove, and the outer shell 1 is provided with a second mounting groove.
