All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in figures 1, 2 and 3, this embodiment provides a multi-angle adjustable retractor. The multi-angle adjustable drag hook comprises a handle 1, an anti-rotation block 2, a hook body 3 and a control mechanism 4. The control mechanism 4 is used for controlling whether the anti-rotation block 2 and the hook body 3 can be separated or not. When the anti-rotation block 2 and the hook body 3 are locked, the hook body 3 rotates, and when the anti-rotation block 2 and the hook body 3 are separable, the angle of the hook body 3 can be adjusted, so that the operation is convenient to carry out.
As shown in fig. 4, the handle 1 includes a body 11 and a mounting portion 12. The body 11 is a slender cuboid, which is convenient for the operating personnel to hold. The body 11 includes opposite first and second ends 11a, 11 b. The mounting portion 12 is provided at the first end 11a of the body.
The anti-rotation block 2 is slidably disposed on the mounting portion 12, in this embodiment, the sliding direction of the anti-rotation block 2 is parallel to the long side 11c of the body 11, that is, the anti-rotation block 2 slides along the X direction. The hook 3 is hinged to the mounting 12, the hook 3 being rotatable about an axis parallel to the short sides of the body 11, i.e. the hook 3 being rotatable about an axis in the Y-direction.
The control mechanism 4 is used for controlling whether the anti-rotation block 2 can slide or not. When the control mechanism 4 limits the sliding of the anti-rotation block 2, the anti-rotation block 2 locks the hook body 3, and the hook body 3 cannot rotate. When the control mechanism 4 does not limit the sliding of the anti-rotation block 2, the anti-rotation block 2 unlocks the hook body 3, and the hook body 3 can rotate so as to adjust the hook body 3 to a required angle.
According to the multi-angle adjustable drag hook, when the angle of the hook body 3 needs to be adjusted, the hook body 3 is unlocked, and an operator can manually adjust the angle of the hook body 3 so as to adjust the drawing direction of the drag hook; after the angle of the hook body 3 is adjusted in place, the hook body 3 is locked through the anti-rotation block 2, the angle of the hook body 3 is fixed, and the change of the angle is avoided.
As shown in fig. 5, according to an alternative embodiment of the present application, an end surface of the anti-rotation block 2 away from the first end 11a of the body is an inward-concave arc surface 21, and a plurality of first gear teeth 211 are sequentially arranged on the inward-concave arc surface 21. The end surface of the hinged end of the hook body 3 is an outward convex cambered surface 31, and a plurality of second gear teeth 311 are sequentially arranged on the outward convex cambered surface 31. Second gear teeth 311 mesh with first gear teeth 211. When the anti-rotation block 2 is restricted from sliding, the second gear teeth 311 are engaged with the first gear teeth 211 to restrict the rotation of the hook body 3. When the rotation preventing block 2 is slidable, the engagement of the second gear teeth 311 with the first gear teeth 211 is separable, so that the hook body 3 can be rotated.
As shown in fig. 6, according to an alternative embodiment of the present application, the mounting portion 12 includes a first support portion 121 and a second support portion 122 disposed in parallel with each other. The first support part 121 and the second support part 122 of the present embodiment are each approximately rectangular parallelepiped. The first supporting part 121 and the second supporting part 122 are respectively connected with the first end 11a of the body, and the first supporting part 121, the second supporting part 122 and the first end 11a of the body form a three-sided closed installation space. The anti-rotation block 2 is slidably disposed in the installation space.
As shown in fig. 7, according to an alternative embodiment of the present invention, the top and bottom of the inner side of the first support part 121 and the top and bottom of the inner side of the second support part 122 are provided with guide surfaces 125, respectively. The guide surface 125 extends in the X direction. In this embodiment, the guide surface of the top of the first supporting portion 121 and the guide surface of the top of the second supporting portion 122 are connected at the first end 11a of the body 1 to form an integral plane. The guide surface of the bottom of the first support 121 and the guide surface of the bottom of the second support 122 are connected at the first end 11a of the body 1 to form another integral plane.
As shown in fig. 8, guide grooves 22 corresponding to the guide surfaces 125 are provided on both sides of the rotation preventing block 2. The rotation preventing block 2 is slidable along the guide surface 125 through the guide groove 22, so that the rotation preventing block 2 is slidably disposed between the first support part 121 and the second support part 122.
According to an optional technical scheme of the application, the anti-rotation block 2 is provided with a hole group 23, and the hole group 23 penetrates through the side walls of two sides of the anti-rotation block 2. The first support part 121 is provided with a first stepped hole 123, the first stepped hole 123 includes a large diameter portion and a small diameter portion which are communicated, and a large diameter portion of the first stepped hole 123 is close to an outer side surface of the first support part 121. The inner side surface of the second support part 122 is provided with a first blind hole 124 corresponding to the first stepped hole 123.
As shown in fig. 9 and 10, the control mechanism 4 includes: a stepped shaft 41, a first elastic member 42, a second elastic member 43, and a pressing member 44.
As shown in fig. 11 and 12, the stepped shaft 41 includes a first large diameter portion 411, a second large diameter portion 413, and a small diameter portion 412 located between the first large diameter portion 411 and the second large diameter portion 413. The first large diameter portion 411 and the second large diameter portion 413 both have a diameter D1, and the small diameter portion 412 has a diameter D2 smaller than the diameter D1. The stepped shaft 2 is inserted into the first stepped hole 123 and the hole group 23 of the anti-rotation block. Alternatively, the second large diameter portion 413 of the stepped shaft 2 of the present embodiment penetrates into the first blind hole 124.
The first elastic element 42 is disposed in the first blind hole 124 and located between the bottom surface of the first blind hole 124 and the end surface of the second large-diameter portion 413 of the stepped shaft. The elastic force of the first elastic member 42 moves the stepped shaft 41 toward one end of the first large diameter portion 411.
The second elastic member 43 is disposed between the rotation preventing block 2 and the end surface of the first end 11a of the body. The elastic force of the second elastic member 43 moves the rotation preventing block 2 in a direction away from the first end 11a of the body.
The pressing member 44 is used to control the engagement of the stepped shaft 41 with the hole group 23 to control whether the anti-rotation block 2 is slidable. The operator presses the pressing component 44, and the anti-rotation block 2 can slide; the operator releases the pressing assembly 44 and the sliding of the anti-rotation block 2 is limited.
As shown in fig. 13, the hole group 23 of the rotation prevention block includes: round hole 231, elongated hole 232, elongated hole 233. A round hole 231 and a long hole 232 are provided on the side of the rotation preventing block 2 close to the first support part 121. The circular hole 231 communicates with the elongated hole 232, and the circular hole 231 is located near the first end 11a of the body with respect to the elongated hole 232. The elongated hole 232 extends in a direction parallel to the sliding direction of the rotation preventing block 2. The diameter D3 of the circular hole 231 is larger than the width D4 of the elongated hole 232, and the width D4 of the elongated hole is smaller than the diameter D1 of the second large diameter portion of the stepped shaft and larger than the diameter D2 of the small diameter portion of the stepped shaft. The second large diameter portion 413 of the stepped shaft can penetrate into the circular hole 231 but cannot enter into the elongated hole 232. The oblong hole 233 is provided on the side surface of the rotation prevention block 2 near the second support portion 122, and the round hole 231 and the oblong hole 232 are both communicated with the oblong hole 233. The diameter D5 of oblong aperture 233 is equal to the diameter D3 of circular aperture 231. The oblong hole 233 extends in a direction parallel to the sliding direction of the anti-rotation block 2.
When the operator does not operate the pressing member 44, the second large-diameter portion 413 of the stepped shaft is located in the circular hole 231 due to the elastic force of the first elastic member 42. Since the second large diameter portion 413 cannot enter the elongated hole 232, the stepped shaft 41 restricts the rotation preventing block 2 from sliding, and the rotation preventing block 2 locks the hook body 3.
When the operator presses the pressing member 44, the stepped shaft 41 moves toward one end of the second large diameter portion 413, the second large diameter portion 413 moves out of the circular hole 231, the small diameter portion 412 of the stepped shaft 2 enters the circular hole 231, and the stepped shaft 42 cannot limit the sliding of the rotation preventing block 2 because the small diameter portion 412 can slide into the long hole 232.
After the hook body 3 is unlocked, the hook body 3 is rotated, when the second gear teeth 311 slide out of the tooth grooves of the first gear teeth 211, the rotation preventing block 2 is stressed to slide towards the first end 11a close to the body, and the second elastic piece 43 is compressed. The second gear teeth 311 slide over the tooth tops of the first gear teeth 211 and then enter the tooth spaces of the first gear teeth 211 again, and the elastic force of the second elastic member 43 pushes the anti-rotation block 2 to slide towards the first end 11a far away from the body. Due to the cooperation of the second gear 311 and the first gear 211, the anti-rotation block 2 may slide back and forth many times during the angle adjustment of the hook body 3. After the hook 3 is adjusted to the proper position, the pressing member 44 is released, and the second large-diameter portion 413 of the stepped shaft moves into the circular hole 231, thereby restricting the sliding of the rotation preventing block 2 again.
As shown in fig. 6 and 14, the large diameter portion of the first stepped hole 123 is provided with a pin hole 128. The pin hole 128 penetrates the top and bottom surfaces of the first support part 121. The pressing assembly 44 includes a button 441 and a stopper pin 443. The button 441 is disposed at a large diameter portion of the first stepped hole 123, and a slide hole 442 is disposed at a sidewall of the button 441. The sliding hole 442 extends in a direction parallel to the axis of the button 441. The retaining pin 443 is disposed in the pin hole 128, and the retaining pin 443 passes through the sliding hole 442, so that the button 441 is slidable relative to the retaining pin 442. The bottom surface of the button 441 is in close contact with the end surface of the first large diameter portion 411 of the stepped shaft. Pressing the button 441 moves the stepped shaft 2 toward one end of the second large diameter portion 413, thereby unlocking the hook body 3. Alternatively, the button 441 and the stepped shaft 41 may be integrally formed.
According to an alternative embodiment of the present application, a second blind hole 111 is provided on the end surface of the first end 11a of the body. One end of the second elastic member 43 is located in the second blind hole 111 to facilitate the installation of the second elastic member 43.
