Technical Field
[0001] The utility model relates to the technical field of hook manufacturing, in particular to a hook closer. Background Art
[0002] The traditional method of closing hooks usually relies on manual operation, which requires two production personnel to work together. One of them holds the hook to be closed with pliers, and the other uses a rubber hammer to knock on the closing part of the hook to achieve the closure of the hook. Although this manual operation mode meets the basic production needs to a certain extent, with the development of the manufacturing industry towards automation and intelligence, its disadvantages are becoming increasingly prominent.
[0003] At present, the closing method by manual knocking is cumbersome to operate, requires high skills of the operator, and requires close cooperation between two people, which not only increases the labor cost, but also reduces the flexibility of production. During the long working process, the operator is prone to fatigue, which in turn affects the work efficiency and closing quality. Therefore, a hook closer is proposed. Utility Model Content

[0008] In a possible design, extension shafts are fixedly connected to both sides of the rack, and sliding grooves are provided on both inner walls of the connection box, and the extension shafts are slidably connected in the sliding grooves.
[0009] In a possible design, an elastic element for resetting is fixedly connected between the bottom of the mounting block and the top of the sleeve 1, and the elastic element is sleeved on the circumferential outer wall of the connecting rod.
[0010] In a possible design, a handle for facilitating the rotation of the rotating shaft is fixedly connected to the other side of the circumferential outer wall of the rotating shaft.
[0011] In a possible design, a groove is formed at the bottom of the upper die, and a plurality of fixing slots are formed at the top of the lower die and the top of the groove.

[0015] In the utility model, the hook closer can fix the hook to be closed by using the fixing slot provided on the side where the lower die and the upper die are close to each other, thereby improving the performance stability and the yield rate;
[0016] In the utility model, the hook closer can simplify the operation steps by setting the handle and utilizing the cooperation of the driving mechanism, the lower pressing die and the upper pressing die, so as to realize single-person operation, improve production efficiency and reduce costs;

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] Example 1
[0025] Reference Figure 1-Figure 4A closer comprises a chassis 1, which serves as the basic supporting component of the entire closer, and the top of which is firmly connected to a lower die 2 and a base 6 by bolts, a support rod 7 is fixed inside the base 6, and a sleeve 2 16 is fixedly connected to the top of the support rod 7 for subsequent connection and support structure, an upper die 3 is designed to be a shape adapted to the lower die 2 to ensure that the hook can be accurately aligned and pressed during the closing process, and a connecting rod 4 is connected to the top of the upper die 3 by bolts, and the connecting rod 4 can slide freely in the sleeve 1 5, thereby realizing the function of moving up and down, and the sleeve 1 5 is fixed above the base 6 and connected to the sleeve 2 16 by a connecting box 14 to form a stable frame structure;
[0026] In order to realize the automatic pressing down of the upper die 3, a driving mechanism consisting of a rotating shaft 9, a gear 12 and a rack 13 is adopted in this embodiment. The rack 13 is fixed to the bottom of the mounting block 8 by bolts, and the mounting block 8 is connected to the top of the connecting rod 4 by bolts. The other end of the rack 13 slides through the top of the connecting box 14 so that it can move smoothly when driven. The rotating shaft 9 rotates to penetrate one side of the connecting box 14, and a gear 12 is fixedly connected to one side of its circumferential outer wall. The gear 12 is meshed with the rack 13, so that the rack 13 is driven up and down by rotating the rotating shaft 9, thereby driving the upper die 3 to be pressed down or reset;
[0027] In order to improve the stability of the rack 13 in movement, extension shafts 19 are fixedly connected to both sides of the rack 13. These extension shafts 19 are slidably connected to the slide grooves 20 opened on the inner walls of both sides of the connection box 14, which effectively prevents the rack 13 from deflecting during movement;
[0028] In addition, in order to realize the automatic reset of the upper die 3, an elastic element 11, such as a spring, is fixedly connected between the bottom of the mounting block 8 and the top of the sleeve 5. The elastic element 11 is sleeved on the circumferential outer wall of the connecting rod 4. When the external force is released, the upper die 3 can be pushed back to its original position by its own elastic force.
[0029] For the convenience of operation, a handle 10 is fixedly connected to the other side of the circumferential outer wall of the rotating shaft 9. The user can easily control the rotation of the rotating shaft 9 by rotating the handle 10, thereby driving the upper die 3 to complete the closing action. A groove 17 is designed at the bottom of the upper die 3 to accommodate and position the hook to be closed, and a plurality of fixed slots 18 are provided at the top of the lower die 2 and the top of the groove 17. These slots are symmetrically distributed up and down, and the spacing between the slots on the same horizontal line is equal, ensuring that the hook can be firmly inserted and fixed in the slot when closed.
