DETAILED DESCRIPTION
[0026] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.
[0027] See also Figures 1 to 5 As shown, a structurally improved hook of the utility model comprises a hook 1 for hanging on an external target part; it also comprises a pressing rod 2 rotatably matched with the hook 1, and a first elastic member 3 for driving the pressing rod 2 to contact and close with the hook; one end of the hook 1 is provided with a first groove 13 for accommodating the first elastic member 3, the first elastic member 3 comprises a reset spring 31, and an auxiliary member 32 abutting with the reset spring 31; one end of the auxiliary member 32 away from the reset spring 31 abuts against one end of the pressing rod 2, and the other end of the pressing rod 2 abuts against and closes with the other end of the hook 1.
[0028] The pressing rod 2 is provided with a first protrusion 21, and the hook 1 is provided with a first opening 11 and a receiving hole 12 for receiving the first protrusion 21. The receiving hole 12 is coaxially arranged with the first protrusion 21. The pressing rod 2 is rotatably matched with the hook 1 through the cooperation between the first protrusion 21 and the receiving hole 12. The pressing rod 2 rotates around the first protrusion 21 to move away from or approach the hook 1 to open and close the first opening 11 to hang the hook 1 on an external target part.
[0029] In this embodiment, the outer shape of the hook 1 is roughly a "C" shape, the pressing rod 2 is roughly a cylindrical rod body, and the "C"-shaped opening is the first opening 11 of the hook 1; the lower end of the hook 1 is connected to a plate body 5 that is approximately rectangular, and a mounting position 51 is opened on one side of the plate body 5, and the accommodating hole 12 is located in the mounting position 51. After one end of the pressing rod 2 enters the mounting position 51, it is rotatably connected to one end of the hook 1 through the snap fit of the first protrusion 21 and the accommodating hole 12, and the other end of the pressing rod 2 can reciprocate with the first protrusion 21 as the axis to close or open the first opening 11.
[0030] Specifically, the accommodating hole 12 is a blind hole. In this embodiment, there are two blind holes, and the number of the first protrusions 21 matches the number of the blind holes. The blind holes are located on the inner side of the plate body 5 near the mounting position 51. Since the blind holes do not penetrate the plate body 5, the outer structure of the plate body 5 is intact. Compared with the design of penetrating the plate body 5, this method avoids the phenomenon of a gap between the first protrusion 21 and the plate body 5 to hide dirt and grime, and further prevents the situation where the pressing rod 2 remains unchanged due to long-term use.
[0031] Specifically, the end of the pressing rod 2 close to the first protrusion 21 is provided with a second protrusion 22, and the outer end surface of the second protrusion 22 is an arc-shaped surface. When one end of the pressing rod 2 swings back and forth relative to the hook 1, a certain friction force will be generated. If the distance between the pressing rod 2 and the mounting position 51 is increased, although more friction is avoided, the structural strength of the pressing rod 2 will be relatively reduced, which is not conducive to the long-term use of the hook. Therefore, the present solution adds a second protrusion 22, utilizes the second protrusion 22 to conflict with the inner side of the mounting position 51 of the plate body 5, and sets the pressure-bearing surface of the second protrusion 22 to an arc-shaped surface, so as to further reduce the friction force of the pressing rod 2 when swinging.
[0032] In actual manufacturing, the second protrusion 22 can be set as a ball, and the ball is used to contact the inner side of the installation position 51 of the plate body 5 to achieve the effect of reducing friction.
[0033] Specifically, the protrusion is an integral structure with the pressing rod 2. In this embodiment, the first protrusion 21 and the second protrusion 22 are integrally arranged with the pressing rod 2 by cutting, grinding, etc. Compared with the pin-hole matching in the prior art, this method improves the deviation phenomenon of the pressing rod 2 when the pressing swing is performed, and at the same time, further reduces the gap between the protrusion and the pressing rod 2, preventing the pressing obstruction caused by dust entering the gap after long-term use.
[0034] Specifically, the end of the pressing rod 2 away from the first protrusion 21 and the end of the hook 1 away from the accommodating hole 12 are inclined surfaces, and the inclination angles of the two inclined surfaces relative to the length direction of the pressing rod 2 are complementary. The setting of the inclined surface can make the pressing rod 2 swing toward the inside of the "C"-shaped hook 1 when pressed, and the reset after the swing also makes the two inclined surfaces conflict with each other again, preventing the pressing rod 2 from continuing to swing toward the outside of the "C"-shaped hook 1. In this embodiment, the inclined surface of the hook 1 serves as the first inclined portion, and the inclined surface of the pressing rod 2 serves as the second inclined portion. The first inclined portion is provided with a raised strip 16, and the second inclined portion is provided with a groove 23 that matches the raised strip 16, which further prevents excessive swinging of the pressing rod 2 when it is reset; in actual production, the positions of the raised strip 16 and the groove 23 can also be interchanged.
[0035] Specifically, the auxiliary component 32 has a thin rod 321 and a thick rod 322 connected to the thin rod 321. The return spring 31 is sleeved on the outside of the thin rod 321 and abuts against the end of the thick rod 322 close to the thin rod 321. The end of the thick rod 322 away from the thin rod 321 is provided with a convex spherical surface for abutting the pressing rod 32.
[0036] Specifically, the end of the hook 1 close to the accommodating hole 12 is provided with a first groove 13, and the first elastic member 3 is located in the first groove 13. In this embodiment, the first groove 13 is opened inside the rectangular plate 5, and the opening direction of the first groove 13 intersects with the swing direction of the pressing rod 2 (the first groove 13 is inclined). Under the action of the first elastic member 3, after the user presses the pressing rod 2, the pressing rod 2 can automatically return to close the first opening 11 without being affected by external force.
[0037] The auxiliary part 32 in this embodiment is roughly cylindrical, and the end surface of the auxiliary part 32 that contacts the pressing rod 2 is set to a hemispherical surface. Compared with only setting the reset spring 31 or setting the end surface of the auxiliary part 32 as a plane, the design of this scheme makes the pressing rod 2 smoother and more unobstructed when performing pressing and resetting actions.
[0038] Specifically, the hook 1 is provided with a second groove 121 at one end close to the receiving hole 12, and the second groove 121 is connected to the receiving hole 12; the first protrusion 21 enters the receiving hole 12 via the second groove 121 so that the pressing rod 2 and the hook 1 can rotate and cooperate. In this embodiment, the side wall of the second groove 121 is an arc, and similarly, the outer cross-section of the first protrusion 21 is also set as an arc surface. Compared with the flat design of the two, this structure makes the friction force of the first protrusion 21 smaller when entering the receiving hole 12 with the help of the second groove 121, which is convenient for installation and disassembly.
[0039] Specifically, the improved hook also includes a ring member 4 detachably connected to the hook 1, and the ring member 4 is used to limit the position of an external target object. The ring member 4 in this embodiment is used to limit the position of external key rings or backpack straps, etc. In actual use, the ring member 4 includes but is not limited to limiting the position of the aforementioned objects.
[0040] Specifically, the hook 1 is further provided with a connecting rod 14 at one end close to the accommodating hole 12, and the ring member 4 is provided with a through hole 41 for the connecting rod 14 to pass through. A limiting member 15 is installed on the connecting rod 14, and the limiting member 15 at least partially covers the through hole 41; the ring member 4 is detachably connected to the hook 1 via the connecting rod 14 and the limiting member 15. In this embodiment, the limiting member 15 is a laterally open annular rubber, and a clamping portion 140 for accommodating the annular rubber is provided at the end of the connecting rod 14; after the connecting rod 14 passes through the through hole 41, the annular rubber is sleeved on the clamping portion 140, and the annular member 4 is limited on the hook 1 by the blocking and abutment of the annular rubber against the clamping portion 140 and the ring member 4.
[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
