TECHNICAL FIELD

[0001] The utility model relates to the technical field of bundling machine, specifically discloses a kind of bundling machine of elastic locking silk disc storehouse cover. BACKGROUND

[0002] Bundling machine is a kind of handheld tool widely used in construction field, mainly used for bundling fixed reinforcement with iron wire, to ensure the stability and safety of structure.

The rotating lever is fixed on the shell by connecting with the rotating shaft with a pin, and the spring is responsible for pushing the locking lever against the cover to maintain the closed state of the cover. When replacing the iron wire roll, the user only needs to pull the rotating lever outward and twist it to make it disengage from the pressure holding of the cover, so as to open the cover. However, in actual use, this locking device has the problems of easy breakage, disengagement and other locking failures, and has a short service life, which needs further structural improvement.

[0031] REFERENCE Figures 1-3, the shell 1 is further provided with a telescopic rod 4, an elastic element 5 and a locking knob 6. The telescopic rod 4 is axially movable in the shell 1, and the shell 1 is circumferentially limited relative to the telescopic rod 4; the elastic element 5 is connected with the telescopic rod 4; the locking knob 6 is connected with the end of the telescopic rod 4 extending out of the shell 1, and the locking knob 6 is circumferentially rotatable relative to the telescopic rod 4; the telescopic rod 4 abuts the locking knob 6 against the shell 1 through the elastic element 5, and the locking knob 6 locks the spool cover 3 on the shell 1. According to the scheme, the circumferential relative positioning is arranged between the telescopic rod 4 and the shell 1, so that only axial relative movement exists between the locking knob 6 and the telescopic rod 4, and when the operator overcomes the elastic force of the elastic element 5 to lift and rotate the locking knob 6 upward, the locking knob 6 will not rotate together with the telescopic rod 4. This design avoids the problems of breakage and falling of the telescopic rod 4 or the locking knob 6 due to operation errors, thereby prolonging the service life of the product.

[0032] Specifically, referring to Figures 3-4 , the telescopic rod 4 has a rod body part 41 and outer circular platform parts 42 and inner circular platform parts 43 connected at both ends of the rod body part 41. The shell 1 is provided with a mounting sleeve 7 having an annular outer cylinder 71 and an annular inner cylinder 72. Part of the rod body part 41 of the telescopic rod 4 is located in the annular inner cylinder 72, the rod body part 41 of the telescopic rod 4 is axially extended to be provided with a limiting plane 411, and the inside of the annular inner cylinder 72 of the mounting sleeve 7 is provided with a plane abutting against the limiting plane 411, so that the shell 1 is circumferentially limited relative to the telescopic rod 4. In other embodiments, the circumferential limiting of the shell 1 relative to the telescopic rod 4 can also be achieved by the clamping cooperation of the strip-shaped grooves and the protrusions.

[0033] The locking knob 6 has a mounting part 61 and a locking part 62, the locking knob 6 is connected with the shell 1 through the mounting part 61, and the spool cover 3 is locked through the locking part 62. The outer end of the mounting part 61 of the locking knob 6 is provided with an annular groove 611 matched with the outer circular platform part 42 of the telescopic rod 4, so that the locking knob 6 is abutted against the surface of the shell 1 by the telescopic rod 4, and the cooperation of the outer circular platform part 42 and the annular groove 611 plays a positioning role. In addition, the shell 1 is provided with an annular convex edge 11 for matching and embedding the mounting part 61 of the locking knob 6, and the outer periphery of the mounting part 61 of the locking knob 6 is provided with an annular positioning groove 612, the annular positioning groove 612 of the locking knob 6 is sleeved with the annular convex edge 11 of the shell 1, and the design of the annular convex edge 11 and the annular positioning groove 612 also plays a positioning role for the locking knob 6, thereby improving the rotation stability of the locking knob 6.

[0034] The elastic member 5 in the scheme is a spring, and the elastic member 5 is located in the annular space between the annular outer cylinder 71 and the annular inner cylinder 72, one end of the elastic member 5 abuts against the inner side wall of the mounting sleeve 7, and the other end abuts against the inner circular table part 43 of the telescopic rod 4, and in other embodiments, a tension spring can also be used as the elastic member 5. The design of the mounting sleeve 7 plays a dustproof protection role on the telescopic rod 4 and the elastic member 5, so that foreign matter cannot enter to affect the normal use, and the structural design of the annular outer cylinder 71 and the annular inner cylinder 72 can separate the telescopic process of the elastic member 5 from the telescopic rod 4, and better improve the use reliability. In addition, the inner circular table part 43 of the scheme moves in the annular outer cylinder 71 and covers at least part of the gap between the annular outer cylinder 71 and the annular inner cylinder 72, further improving the dustproof effect.

[0035] As a preferred scheme, referring to Figures 4-5 , the locking knob 6 is provided with annular stop teeth 613 close to the inner side of the shell 1, and the shell 1 is provided with a stop slot 12 matched with the stop teeth 613. When the operator pulls and twists the locking knob 6 outward, the cooperation of the stop slot 12 and the stop teeth 613 plays a role in positioning the angle of the locking knob 6, and even if the operator does not place the bundling machine horizontally, the locking knob 6 will not sag due to gravity, but will remain at the angle position after twisting, which is more convenient to use. Specifically, the stop teeth 613 of the scheme include spaced apart sharp tooth parts and groove parts, and a transition slope is arranged between the sharp tooth parts and the groove parts, and the angle locking effect is more obvious by arranging the sharp tooth parts and the groove parts and arranging the transition slope interval.
