Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a straight-handled mountain hook assembly. Background Art

[0002] Straight shank double hooks are made from materials specified in GB / T10051-88 and GB / T10051-2010 standards, including DG20, DG20Mn, DG34CrMO, DG34CrNiMo, DG30Cr2Ni2Mo, Q355D, Q420D, 35CrM0, 34Cr2Ni2M0, and 30Cr2Ni2Mo. These are smelted in electric furnaces and forged into blanks. These are then machined and formed, with heat treatment processes, temperatures, and times strictly controlled. Ultrasonic testing and mechanical property testing are performed to ensure the product's fine metallographic structure, uniform grain size, and structural uniformity. The product boasts a beautiful, regular appearance, precise dimensions, and a vertical center of gravity. This prevents burnt defects on the hook surface caused by gouging or cutting.

[0032] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] See Figure 1-Figure 3 This embodiment discloses a hook assembly, specifically a straight-shank shank hook assembly, including a shank hook body 101. A connecting unit 102 is provided on the top of the shank hook body 101. The connecting unit 102 includes:

[0035] A base 103 is provided with a through hole 105 for the upper end of the mountain hook body 101 to pass through, and an annular support platform 106 is provided on the surface of the base 103;

[0036] A connecting base 104 is provided with a first threaded hole 107 and a positioning groove 108 on the side of the connecting base 104 facing the base 103;

[0037] Among them, after the upper end of the mountain hook body 101 passes through the through hole 105 and is connected to the first threaded hole 107, the positioning groove 108 on the connecting seat 104 contacts the annular support platform 106, and lifting handles 110 are set on both sides of the base 103.

[0038] In actual use, the present invention connects the mountain-shaped hook body 101 with the connecting seat 104, and supports the connecting seat 104 through the annular support platform 106 provided on the base 103, so that the overall structure is subjected to more reasonable force, and the force is dispersed to the base 103. At the same time, lifting handles 110 are provided on both sides of the base 103 to achieve lifting. The present invention can effectively solve the technical problem in the prior art that after the mountain-shaped hook body 101 is directly connected to the connecting seat 104, the straight-handled mountain-shaped hook and the connecting seat 104 are prone to force at the connection point, resulting in stress concentration.

[0039] Furthermore, an anti-slip groove 109 is provided at the end of the lifting handle 110. The anti-slip groove 109 can prevent the cable from slipping off and ensure stability during the lifting process.

[0040] Furthermore, the upper end of the chevron hook body 101 has a stepped shoulder 111, and the base 103 is provided with a first inclined surface 112 connected to the through hole 105. The first inclined surface 112 contacts the inclined surface at the stepped shoulder 111, and the stepped shoulder 111 can serve the purpose of limiting. After the chevron hook body 101 is threadedly connected to the connecting seat 104, the connecting seat 104 presses the base 103 tightly against the stepped shoulder 111, so that the structure formed after the chevron hook body 101, the base 103 and the connecting seat 104 are connected is more stable.

[0041] Furthermore, in some preferred implementation cases, an anti-rotation structure is provided between the upper end of the mountain-shaped hook body 101 and the connecting seat 104; the anti-rotation structure includes a first positioning groove 113 provided on the upper end surface of the mountain-shaped hook body 101, and a second positioning groove 114 provided on the surface of the connecting seat 104. The first positioning groove 113 and the second positioning groove 114 are collinear to form a limiting groove 115, and a positioning block 121 is fixedly provided in the limiting groove.

[0042] By cooperating with the positioning block 121 and the limiting groove 115, the U-shaped hook body 101 and the connecting seat 104 can be effectively locked and fixed to prevent the two from loosening after relative rotation; at the same time, the first positioning groove 113 is provided on the end face of the U-shaped hook body 101, which will not affect the force applied to the U-shaped hook body 101.

[0043] The positioning block 121 is provided with a first through hole 116, and the second positioning groove 114 is provided with a second threaded hole corresponding to the first through hole 116. The positioning block 121 is fixedly connected by a screw threadedly connected to the second threaded hole. The screw is used to fix the positioning block 121 and prevent it from falling off.

[0044] In some preferred embodiments, an anti-slip assembly 117 is fixedly mounted on the chevron hook body 101. The anti-slip assembly 117 includes a first fastener 118 and a second fastener 119, which are bolted to the chevron hook body 101. Anti-slip arms 120 are rotatably mounted on the first and second fasteners 118, 119 via a pin and a torsion spring. The torsion spring forces the anti-slip arms 120 into contact with the inner wall of the curved hook of the chevron hook body 101. The present invention is fastened to the chevron hook body 101 via the first and second fasteners 118, 119, without damaging the structure of the chevron hook body 101.

[0045] Among them, anti-slip pads are provided on the side where the first fastener 118 and the second fastener 119 contact the mountain hook body 101, which can ensure the fixed position of the first fastener 118 and the second fastener 119 and prevent the first fastener 118 and the second fastener 119 from sliding.

[0046] Furthermore, the end of the anti-slip arm 120 has a fitting portion for matching the inner wall of the curved hook of the mountain hook body 101. This fixes the position of the anti-slip arm 120 and prevents the anti-slip arm 120 from slipping.

[0047] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
