Technical Field
[0001] This utility model relates to a hook for a belt body; in particular, it refers to a detachable hook for fixing accessories to a belt body. Background Technology
[0002] The existing double-headed hook has an opening on each of the upper and lower sides of the hook body, and a spring gate is provided on the hook body corresponding to each opening. The opening can be closed or opened by the spring gate. When the above-mentioned double-headed hook is used, a strap, such as a shoulder strap or seat belt worn on the human body, is placed into one of the openings, and accessories or other items that need to be attached to the shoulder strap or seat belt are placed into the other opening.
[0003] While the aforementioned double-ended hook can be installed on seat belts and other harnesses for attaching accessories, its design with two spring-loaded gates requires the user to press down the gates with their fingers to open the opening while simultaneously guiding the harness into it. This process involves moving the hook relative to the harness and pressing down the gates, reducing operational efficiency. Furthermore, after prolonged use or in harsh environments, the spring gates may fail due to corrosion or elastic fatigue, resulting in incomplete closure of the opening and affecting the stability and reliability of the double-ended hook when installed on seat belts and other harnesses. Summary of the Invention
[0004] In view of this, the purpose of this utility model is to provide a detachable hook with two through holes on the hook body, and the notches of the two through holes are designed with the openings facing opposite positions, making it easy to install the hook on the strap and easy to disassemble when needed. In addition, since the hook body has no movable structure, the structure is durable and safer and more reliable in use.
[0005] To achieve the above objectives, this utility model provides a detachable hook, comprising a hook body and a hooking structure. The hook body includes a first crossbar with a center line; a second crossbar and a third crossbar are respectively arranged on both sides of the first crossbar perpendicular to the center line; the extension directions of the second and third crossbars are parallel to the center line; a first side bar is connected between one end of the first crossbar and the corresponding end of the second crossbar; a second side bar is connected between the other end of the first crossbar and the corresponding end of the third crossbar; a first strap through-hole is formed between the first crossbar, the second crossbar, and the first side bar, and the first strap through-hole has a first notch; a second strap through-hole is formed between the first crossbar, the third crossbar, and the second side bar, and the second strap through-hole has a second notch; the opening directions of the second notch and the first notch are respectively facing opposite sides of the center line. The hooking structure is connected to the third crossbar of the hook body on the side opposite to the first crossbar, and a hooking hole is formed on the inner side of the hooking structure.
[0006] The advantage of this invention is that when the detachable hook is fixed to the belt body, the two parts of the same belt body are inserted into the first belt body through-hole and the second belt body through-hole respectively through the first notch and the second belt body through-hole, thus fixing the hook body to the belt body. Accessories are then hung using the hook holes of the hook structure. By relatively moving the belt body and the hook body, the hook body can be easily fixed to or detached from the belt body. Furthermore, since the hook body has no movable parts, the structure is durable and safer to use. Attached Figure Description

[0043] To more clearly illustrate this utility model, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figures 1 to 5As shown, a detachable hook 100 according to a preferred embodiment of the present invention includes a hook body 10 disposed on the upper side and a hook structure 20 connected to the lower side of the hook body 10. The hook body 10 of the detachable hook 100 is used to fix to a belt body, for example, detachably fixed to the belt body of a backpack seat belt. In the following description of the detachable hook 100, the detachable hook 100 is defined according to the direction of use as having a vertical direction, a horizontal direction, a direction close to the user's back, and a direction away from the user's abdomen; wherein:
[0044] The hook body 10 includes a first crossbar 12, which is a straight rod extending in the left-right direction with a quadrilateral cross-section. The four corners of the first crossbar 12 each form a first chamfer 121, and the first crossbar 12 has a center line L extending in the left-right direction. A second crossbar 14 and a third crossbar 16 are respectively provided on the upper and lower sides of the first crossbar 12, perpendicular to the center line L; the extension directions of the second crossbar 14 and the third crossbar 16 are each parallel to the center line L.
[0045] The second crossbar 14 is a straight bar with a quadrilateral cross-section, and each of its four corners forms a second chamfer 141. A first side bar 13 is connected between one end of the first crossbar 12 and the corresponding end of the second crossbar 14. The cross-sectional area of the second crossbar 14 gradually decreases from the end where it is connected to the first side bar 13 towards the other end away from the first side bar 13. At the end of the second crossbar 14 away from the first side bar 13, a first hook 142 protrudes towards the second side bar 15.
[0046] A first belt body through hole S1 is formed between the first crossbar 12, the second crossbar 14, and the first side bar 13. The first belt body through hole S1 is an elongated hole extending in the left-right direction and has a first notch S11 at its left end. The first notch S11 is formed between the first hook portion 142 and the second side bar 15, and the opening direction of the first notch S11 faces left. The width H11 of the first notch S11 in the vertical direction perpendicular to the center line L is smaller than the width H1 of the first belt body through hole S1 in the vertical direction perpendicular to the center line L. When the hook body 10 is placed on the belt body, in order to allow the belt body to be smoothly inserted into the first belt body through hole S1 through the first notch S11, for example, when it is necessary to insert a portion of the belt body with a thickness of about 3mm into the first belt body through hole S1 through the first notch, the width H11 of the first notch S11 is usually set to a width between 2mm and 5mm, and the length of the first belt body through hole S1 in the left-right direction along the center line L is greater than the width of the belt body in the left-right direction.
[0047] The third crossbar 16 is a straight rod with a quadrilateral cross-section, and each of its four corners forms a third chamfer 161. A second side bar 15 is connected between the other end of the first crossbar 12 and the corresponding end of the third crossbar 16. The cross-sectional area of the third crossbar 16 gradually decreases from the end of the third crossbar 16 connected to the second side bar 15 towards the other end away from the second side bar 15. At the end of the third crossbar 16 away from the second side bar 15, a second hook portion 162 protrudes towards the first side bar 13.
[0048] A second strip through hole S2 is formed between the first crossbar 12, the third crossbar 16 and the second side bar 15. The second strip through hole S2 is an elongated hole extending in the left-right direction and has a second notch S21 at the right end. The second notch S21 is formed between the second hook 162 and the first side bar 13, and the opening direction of the second notch S21 is to the right. The opening directions of the second notch S21 and the first notch S11 are respectively facing opposite sides of the center line L.
[0049] The width H21 of the second notch S21 along the vertical direction perpendicular to the center line L is smaller than the width H2 of the second strap perforation S2 along the vertical direction perpendicular to the center line L. To allow the strap to be smoothly inserted into the second strap perforation S2 through the second notch S21, for example, when another portion of the approximately 3mm thick strap is inserted into the second strap perforation S2 through the second notch S21, the width H21 of the second notch S21 is typically set to be between 2mm and 5mm, and the length of the second strap perforation S2 along the left-right direction of the center line L is greater than the width of the strap along the left-right direction. The hook body 10 forms a first back surface 11 on its surface facing the back side.
[0050] The hook structure 20 has two ends and is connected to both ends of the third crossbar 16, thereby connecting the hook structure 20 to the side of the third crossbar 16 away from the first crossbar 12. A hook hole S3 is formed on the inner side of the hook structure 20, which allows accessories to be hung. In this preferred embodiment, the hook structure 20 includes two bent arms 22, which are curved rods connected to both ends of the third crossbar 16. The outer ends of the two bent arms 22 each form an end face 221. The two end faces 221 face each other and form a gap S4 between them. The width H3 of the gap S4 along the center line L is less than 3mm, and the gap S4 communicates with the hook hole S3. The hook structure 20 forms a second back surface 21 on the surface facing the back side. There is an included angle θ between the first back surface 11 and the second back surface 21, and the included angle θ is 30 degrees. In other preferred embodiments, the included angle θ may also be between 0 degrees and 60 degrees.
[0051] Please refer to Figures 2 to 5 As shown, when the detachable hook 100 of the above-described preferred embodiment of this utility model is used, the detachable hook 100 is fixed to the strap of, for example, a backpack safety belt. Two adjacent portions of a section of the strap are inserted into the first strap through-hole S1 and the second strap through-hole S2 through the first notch S11 and the second strap through-hole S2, respectively. The portion of the strap passing through the first strap through-hole S1 and the second strap through-hole S2 rests against the front of the first crossbar 12, thus easily fixing the hook body 10 to the strap. Furthermore, since the hook body 10 has no movable parts, the structure is durable and safer to use.
[0052] When the strap is kept straight, since the first notch S11 and the second notch S21 open in opposite directions, even if the hook body 10 is twisted, as long as the different parts of the strap are not pulled out of the first notch S11 and the second notch S21 from different directions, the hook body 10 can be firmly attached to the strap and will not fall off. The hook hole S3 of the hook structure 20 is then used to hang climbing tools and other accessories. When the angle θ between the second back side 21 of the hook structure 20 and the first back side 11 of the hook body 10 is greater than 0 degrees, the hook structure 20 will be suspended relative to the hook body 10, preventing friction between the accessories suspended in the hook hole S3 and the user's abdomen. The first hook 142 and the second hook 162 corresponding to the first notch S11 or the second notch S21 prevent the belt from being easily moved out of the first notch S11 and the second notch S21 before it is moved by the user.
[0053] The hook structure 20 of the detachable hook 100, through the aforementioned gap S4, allows each bent arm 22 to be easily bent under force. When the hook body 10 is fixed to the user's seat belt, and the accessory hooked to the hook hole S3 is subjected to an external force sufficient to bend each bent arm 22, the design of each bent arm 22 bending after bearing a certain force causes the accessory subjected to external force to fall off the hook structure 20 due to the bending and damage of each bent arm 22, preventing the accessory from pulling on the hook body 10 attached to the seat belt and protecting the safety of the seat belt wearer. In other preferred embodiments, the two bent arms 22 can also be connected as one unit. In this case, the safety function of the hook structure 20 being able to be destroyed when subjected to strong pulling can still be provided by reducing the cross-sectional area of the middle of the upper side of the hook structure 20.
[0054] The above description is only a preferred and feasible embodiment of this utility model. Any equivalent changes made by applying the specification and claims of this utility model should be included within the patent scope of this utility model.
