[0030] Embodiment 1

[0031] Figures 1 to 7 Schematically shows the flat-push type safety self-locking hook of the present utility model.

[0032] As Figure 1 shown, this embodiment provides a flat-push type safety self-locking hook, which includes a first cover plate 1 and a second cover plate 2 that are buckled with each other. A working space 3 is provided between the first cover plate 1 and the second cover plate 2. It further includes a rotating member 4 disposed in the working space 3 and rotating under the friction of the rope;

[0033] A detachable hook 5 disposed between the first cover plate 1 and the second cover plate 2 and an anti-disengagement lock catch 51 that cooperates with the hook 5;

[0034] An anti-disengagement catch mounting block 52 is provided on the first cover plate 1. One end of the anti-disengagement lock catch 51 is movably mounted on the anti-disengagement catch mounting block 52, and the other end abuts against the hook 5 for closing the notch of the hook 5. At the same time, a limiting groove is provided on the inner side surface of the end of the anti-disengagement catch mounting block 52. The other end of the anti-disengagement lock catch 51 is received and abuts in the limiting groove. A hook support block 6 is provided inside the first cover plate 1. The hook 5 is sleeved on the hook support block 6 to achieve detachable connection of the hook. A hook limiting hole 61 is commonly provided between the first cover plate 1 and the second cover plate 2. The hook limiting hole 61 is used to limit the angle of the hook 5 to prevent relative rotation between the hook 5 and the hook support block 6, causing potential safety hazards;

[0035] A mounting hole 13 opened on the side surface of the first cover plate 1;

[0036] The mounting hole 13 is a hexagonal hole, and a lighting lamp 12 can be inserted and mounted on the mounting hole 13, which can play a lighting function when used at night, facilitating night use and at the same time having a warning effect.

[0037] A limiting push rod 21 disposed in the working space 3 for enabling the rotating member 4 to rotate only in one direction;

[0038] In order to ensure that the rotating member 4 can only rotate in one direction, a limiting push rod 21 is provided to control the rotation direction of the rotating member 4, increasing the safety during use.

[0039] Combined with Figure 5As shown, the rotating member 4 includes a first gear 41 rotatably connected to the first cover plate 1 and a second gear 42 rotatably connected to the second cover plate 2. The first gear 41 and the second gear 42 are fixedly connected. On one side of the first gear 41 close to the first cover plate 1, a plurality of limiting platforms 411 are evenly arranged along the circumferential direction of the first gear 41 itself.

[0040] In this embodiment, when the first gear 41 and the second gear 42 are connected, a lifting rope is placed between the first gear 41 and the second gear 42. Transmission pieces 413 for increasing the friction with the lifting rope are arranged on the mutually close side surfaces of the first gear 41 and the second gear 42. A plurality of transmission pieces 413 are evenly arranged along the circumferential direction of the gear. When the lifting rope is lapped on the transmission pieces of the two gears and a heavy object is connected to the lower end of the lifting rope, as the tension received by the lifting rope gradually increases, the friction between the lifting rope and the gear is greater, and the transmission effect is better.

[0041] Combined with Figure 6 As shown, a socket hole 412 is arranged in the first gear 41, and a socket rod 421 is arranged on the second gear 42. The socket rod 421 and the socket hole 412 are tightly connected by stamping.

[0042] In this embodiment, the outer diameter of the socket rod 421 gradually increases from the side far away from the second gear 42 to the side close to the second gear 42. During installation, the socket rod 421 on the second gear 42 is inserted into the socket hole 412 in the first gear 41, and then the two are pressed tightly by using stamping equipment, so that the first gear 41 and the second gear 42 are tightly and fixedly connected. Compared with the prior art, the stamping method is more material-saving and the connection is more stable than the connection method using screws and nuts. The situation that the two gears are separated due to the loosening of the nut will not occur, and the installation is more convenient.

[0043] Combined with Figures 3 - 4 As shown, a torsion spring is connected between the limit push rod 21 and the second cover plate 2. An anti-slip push button 211 is arranged on the limit push rod 21, and a sliding groove 22 is opened on the second cover plate 2. The anti-slip push button 211 slides in the sliding groove 22.

[0044] In this embodiment, the limit push rod 21 abuts against the limiting platform 411 on the first gear 41 under the action of the torsion spring, so as to limit the first gear 41 and prevent it from rotating in the reverse direction, so that the first gear 41 only rotates in the forward direction. When the limit needs to be released, only by pushing the anti-slip push button 211 can the limit push rod 21 be driven to rotate and disengage from the limiting platform 411, so that the first gear 41 can rotate freely. Compared with the prior art, when the torsion spring breaks in the structure of the pressing contact limit itself, the first gear 41 can still be limited by the self-gravity of the limit push rod 21 moving downward.

[0045] Combined with Figure 1As shown, a fastening connection block 11 is disposed on the outer side of the second cover plate 2 , and a fastening connection hole 111 is opened on the fastening connection block 11 .

[0046] In this embodiment, a fastening connection block 11 and a fastening connection hole 111 are additionally provided, and a rope can be passed through the fastening connection hole 11 to increase the practicality of the device and the diversity of connection with the suspension rope.

[0047] Combination Figure 1 As shown, the first cover plate 1 and the second cover plate 2 are connected by means of threads and screws.

[0048] In this embodiment, the first cover plate 1 and the second cover plate 2 can be detachably connected by means of screws and threads, and the hook 5 can be easily replaced, thereby increasing practicality.

[0049] Combination Figure 4 As shown, after the first cover plate 1 and the second cover plate 2 are buckled together, a hanging rope inlet 9 and a hanging rope outlet 8 are jointly opened, and the hanging rope inlet 9 and the hanging rope outlet 8 are communicated.

[0050] In this embodiment, the sling rope passes through the sling rope inlet 9, passes through the rotating member 4 and passes out from the sling rope outlet 8, and the sling rope is placed on the rotating member 4, so that the sling rope can only rotate forward and cannot rotate reversely when in use.

[0051] Combination Figures 2 - 3 As shown, after the first cover plate 1 and the second cover plate 2 are buckled together, the sliding groove 22 and the center line of the mounting hole 13 are coincident.

[0052] In this embodiment, the mounting hole 13 has multiple uses. When the hook 5 or the anti-drop hook 51 is broken, the lighting lamp 12 is taken out from the mounting hole 13, and the suspension rope is passed through the mounting hole 13 and out of the sliding groove 22 of the second cover plate 2, thereby increasing the safety performance and emergency measures. At the same time, the sliding groove 22 is arranged to coincide with the center line of the mounting hole 13 to increase the efficiency of rope threading, avoid the difficulty of rope threading caused by the uneven hole positions of the two, and affect the use in extreme situations.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
