Description

Technical Field

[0001] The present application belongs to the field of electric bicycle accessories, and specifically relates to a movable snap hook. Background Art

[0002] A hook is mounted on the back of the front windshield of an electric bicycle for hanging items such as handbags, helmets, raincoats, and shopping bags. The hook is threaded into a pre-recorded mounting hole on the bicycle frame via bolts. There are many types of hooks, including standard, hidden, and anti-theft. Standard hooks are simple J- or L-shaped, connecting directly to the bicycle frame without any special structural design. Hidden hooks pop out for the rider to use with a press and remain hidden within the bicycle when not in use. Anti-theft hooks utilize a unique structural design to prevent theft. However, existing hooks cannot be adjusted in length, making them inadequate when a large number of items need to be hung, resulting in drawbacks.

[0003] Chinese patent CN214565859U discloses a lock hook for electric vehicles and motorcycles, comprising a lock hook and an upper hanging hook. The lock hook is V-shaped and includes outer and inner clamping plates of the lock hook and an arc-shaped connecting plate connecting the lower ends of the outer and inner clamping plates. Several auxiliary hooks are provided on the outer wall of the lock hook's outer clamping plate. The lock hook is used to hang an anti-theft lock, the upper hanging hook is used to hang items or bags, and the auxiliary hooks are used to hang more items or bags. By increasing the number of hooks to hang more items, this type of hook occupies a large area. Because the auxiliary hooks protrude, riders are prone to touching the auxiliary hooks and scraping their knees. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a movable spring-loaded hook, which can adjust the length of the hook through the spring-loaded hook, so as to hang more items.

[0005] The technical solution adopted in the present invention is as follows:

[0006] A movable spring-loaded hook comprises a hook body connected to an electric bicycle frame, a hook cover that slides longitudinally along the hook body, and a spring that penetrates the hook cover and restricts its movement. The hook body is provided with a bending portion that extends from the hook body and bends toward the hook cover. A buckle is provided at the end of the bending portion for engaging with the spring catch, and a first spring is provided between the hook cover and the spring catch.

[0007] Furthermore, the hook body is a shell with an opening on one side. The hook body can be, for example, a rectangular parallelepiped, and a hollow cavity is formed inside the hook body. A first door-shaped frame is provided at the position of the opening of the hook body. The width and height of the first door-shaped frame are both smaller than the width and height of the hook body. The two side frames of the first door-shaped frame are respectively provided with outwardly protruding sliding strips, which extend along the height direction of the first door-shaped frame. A channel is formed between the sliding strip and the hook body, and the top corners of the sliding strip are rounded.

[0008] Furthermore, two spaced-apart limiting protrusions are provided on the top frame of the first door-shaped frame, which protrude toward the hook cover. A connecting hole is provided on the side of the hook body opposite to the opening, and the bolt passes through the connecting hole and is connected to the vehicle frame.

[0009] Furthermore, a bending portion extends from the top of the hook body, and the bending portion includes a first bending section connected to the top of the hook body and arranged at an angle to the hook body, and a second bending section integrally connected to the first bending section and arranged parallel to the hook body. There is a certain distance between the second bending section and the hook cover. Articles such as shopping bags and handbags are hung on the hook body between the second bending section and the hook cover, and the hook cover forms a barrier to prevent articles from falling.

[0010] Furthermore, the second bending section is provided with a through slot for setting the buckle, and one side of the through slot is provided with two limiting openings which pass through to the first bending section, and the two limiting openings are arranged at intervals.

[0011] Furthermore, the buckle includes a second spring, spring blocks connected to both ends of the second spring, and a shift rod fixedly connected to the spring blocks.

[0012] Furthermore, the two spring blocks are both right-angled trapezoids, and the plane where the two long right-angled sides are located is against the plane of the through slot away from the hook cover. The inclined surfaces of the two spring blocks are arranged in an eight-shaped shape, and the side surfaces where the two long right-angled sides are located are provided with fixing holes for fixing the lever. The second spring and part of the spring block are arranged in the groove cavity of the through slot, and the other part of the spring block extends out of the through slot. The plane where the short straight side of the spring block is located is located in the through slot, and the lever is L-shaped. The lever includes a first rod inserted into and fixed in the fixing hole and a second rod vertically connected to the first rod. The first rod is connected to the second rod after extending through the limit mouth. The first rod has a certain movable space in the limit mouth. On the one hand, the lever is used to control the contraction and release of the second spring, thereby indirectly controlling the spring block. On the other hand, the lever is used to prevent the spring block from being ejected from the through slot.

[0013] Furthermore, the hook cover includes a main body cover and a second door-shaped frame arranged on the back of the main body cover, the second door-shaped frame surrounds the first door-shaped frame, a slide groove is opened on the side frame of the second door-shaped frame, a slide bar is arranged in the slide groove, the slide groove cooperates with the slide bar, and the hook cover slides up and down along the slide bar, and the main body cover inside the second door-shaped frame is opened with an opening for the spring buckle to pass through, the opening is, for example, rectangular, and a first protrusion supporting the spring buckle is provided below the opening, a second protrusion is provided below the first protrusion, and avoidance grooves are provided on both sides of the first protrusion, and the avoidance grooves are arranged along the length direction of the hook cover. During the upward sliding process of the hook cover, the avoidance groove is used to avoid the limiting protrusion. There is a spacing between the second protrusion and the side frame of the second door-shaped frame. The width of the second protrusion is smaller than the distance between the two limiting protrusions to avoid the limiting protrusion hindering the assembly of the hook body and the hook cover. The protrusion height of the second protrusion relative to the main body cover is greater than the protrusion height of the first protrusion relative to the main body cover. The first protrusion does not protrude to the first door-shaped frame, and the second protrusion protrudes to the first door-shaped frame. A blind hole for fixing the first spring is provided on the main body cover between the first protrusion and the opening.

[0014] Furthermore, the spring buckle includes a push-pull block extending outward through the opening, and a back plate arranged inside the hook cover and connected to the push-pull block. The shape of the push-pull block is adapted to the shape of the opening. The push-pull block is, for example, a rectangular parallelepiped. Positioning grooves are provided on the push-pull block and the back plate. Card grooves are provided on the side groove walls of the positioning grooves. A limiting hole corresponding to the limiting protrusion is provided on the top of the back plate. Under the elastic force of the first spring, the first spring pushes the spring buckle toward the hook body, and the limiting protrusion enters the limiting hole, which is used to prevent the rider from accidentally touching the hook cover upward, causing the hook cover to move along the hook body. Sliding, the push plate presses against the first door-shaped frame, and when the rider pulls out or pushes back the push-pull block, the bottom surface of the push plate slides along the top surface of the first protrusion, the height of the push plate is greater than the height of the push-pull block, and the top surface of the push plate is flush with the top surface of the push-pull block. Preferably, the distance between the bottom surface of the push plate and the top surface of the second protrusion is equal to the shell thickness of the top of the hook body. When the hook cover slides upward to the top of the hook body, the second protrusion presses against the top frame of the first door-shaped frame. At this time, the bottom surface of the push plate is just flush with the top surface of the hook body, so that the spring buckle is smoothly pushed into the second bending section of the bending portion.

[0015] Furthermore, one end of the first spring is fixed to the blind hole, and the other end is fixed to the support plate below the push-pull block. The first spring is in a compressed state, pushing the spring buckle to resist the first door-shaped frame.

[0016] Beneficial effects of the present invention:

[0017] The invention relates to a movable spring-loaded hook, which is connected to the bicycle frame by setting a hook body, a slide bar is provided on the hook body, and a slide groove is provided on the hook cover. The hook cover slides up and down along the slide bar. When the hook cover slides out of the hook body, the hook cover can be used to hang objects, thereby increasing the usable length of the hook cover. A first spring is provided between the hook cover and the spring-loaded hook. Under the elastic force of the first spring, the first spring pushes the spring-loaded hook toward the hook body, and the limiting protrusion enters the limiting hole, so as to prevent the rider from accidentally touching the hook cover upwards, causing the hook cover to slide along the hook body. The hook cover is moved upwards by pulling the push-pull block outwards. When the limiting protrusion exits the limiting hole, the push-pull block is pushed upwards. The push-pull block moves the hook cover upwards along the slide bar to realize the sliding of the hook cover. By setting the bending portion, the buckle and the spring buckle, the spring block gradually enters the positioning groove of the spring buckle through the inclined surface of the spring block. The spring block moves to the position of the slot, the second spring releases the elastic force, the spring block is stuck in the slot, and the spring buckle is locked. The locked spring buckle prevents the hook cover from sliding back to the hook body 1. The hook cover above the buckle can continue to hang items, without increasing the number of hooks and reducing the occupied space. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 As shown, the bending portion 4 extends from the top of the hook body 1. The bending portion 4 includes a first bending section 401 connected to the top of the hook body 1 and arranged at an angle to the hook body 1, and a second bending section 402 integrally connected to the first bending section 401 and arranged parallel to the hook body 1. There is a certain distance between the second bending section 402 and the hook cover 2. Articles such as shopping bags, handbags, etc. are hung on the hook body between the second bending section 402 and the hook cover 2. The hook cover forms a barrier to prevent articles from falling.

[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 As shown, the second bending section 402 is provided with a through slot 403 for arranging the buckle 5 , and one side of the through slot 403 is provided with two limiting openings 404 that pass through to the first bending section 401 , and the two limiting openings 404 are arranged at intervals.

[0040] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 As shown, the buckle 5 includes a second spring 501 , spring blocks 502 connected to both ends of the second spring 501 , and a lever 503 fixedly connected to the spring blocks 502 .

[0041] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 9As shown, the two spring blocks 502 are both in the shape of a right-angled trapezoid, with the plane where the two long right-angled sides are located against the plane of the through slot 403 away from the hook cover 2, and the inclined surfaces of the two spring blocks 502 are arranged in an eight-shaped shape. A fixing hole 504 for fixing the lever 503 is opened on the side where the two long right-angled sides are located. The second spring 501 and part of the spring block 502 are arranged in the groove cavity of the through slot 403, and the other part of the spring block 502 extends out of the through slot 403. Preferably, the plane where the short straight side of the spring block is located is located in the through slot, and the lever 503 is opened. The rod 503 is L-shaped. The lever 503 includes a first rod 5031 inserted into and fixed in the fixing hole 504 and a second rod 5032 vertically connected to the first rod 5031. The first rod 5031 extends through the limiting opening 404 and is connected to the second rod 5032. The first rod 5031 has a certain amount of movable space within the limiting opening 404. On the one hand, the lever is used to control the contraction and release of the second spring, thereby indirectly controlling the spring block. On the other hand, the lever is used to prevent the spring block from being ejected from the through slot.

[0042] like Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 As shown, the hook cover 2 includes a main body cover 201 and a second door-shaped frame 202 arranged on the back of the main body cover 201. The second door-shaped frame 202 surrounds the first door-shaped frame 101. A slide groove 203 is provided on the side frame of the second door-shaped frame 202. The slide bar 102 is arranged in the slide groove 203. The slide groove 203 cooperates with the slide bar 102. The hook cover 2 slides up and down along the slide bar 102. The main body cover 201 inside the second door-shaped frame 202 is provided with an opening 204 for the spring buckle 3 to pass through. The opening 204 is, for example, rectangular. A first protrusion 205 supporting the spring buckle 3 is provided below the opening 204. A second protrusion 206 is provided below the first protrusion 205. Avoidance grooves 207 are provided on both sides of the first protrusion 205. The avoidance grooves are arranged along the hook cover The hook cover is arranged in the longitudinal direction, and in the process of sliding the hook cover upward, the avoidance groove is used to avoid the limiting protrusion. There is a distance between the second protrusion 206 and the side frame of the second door-shaped frame 202. The width of the second protrusion 206 is less than the distance between the two limiting protrusions 103, so as to avoid the limiting protrusion 103 hindering the assembly of the hook body and the hook cover. The protrusion height of the second protrusion 206 relative to the main body cover 201 is greater than the protrusion height of the first protrusion 205 relative to the main body cover 201. The first protrusion 205 does not protrude to the first door-shaped frame 101, and the second protrusion 206 protrudes to the first door-shaped frame 101. A blind hole 208 for fixing the first spring 6 is provided on the main body cover 201 between the first protrusion 205 and the opening 204.

[0043] like Figure 3 、 Figure 8 、 Figure 9As shown, the spring buckle 3 includes a push-pull block 301 extending outward through the opening 204, and a push-pull plate 302 arranged inside the hook cover 2 and connected to the push-pull block 301. The shape of the push-pull block 301 is adapted to the shape of the opening 204. The push-pull block 301 is, for example, a rectangular parallelepiped. A positioning groove 303 is provided on the push-pull block 301 and the push-pull plate 302. A card groove 304 is provided on the side groove wall of the positioning groove 303. A limiting hole 305 corresponding to the limiting protrusion 103 is provided on the top of the push-pull plate 302. Under the elastic force of the first spring 6, the first spring 6 pushes the spring buckle 3 toward the hook body 1, and the limiting protrusion 103 enters the limiting hole 305, which is used to prevent the rider from accidentally touching the hook cover 2 upward, causing the hook cover 2 to move along the hook The main body 1 slides and the support plate 302 is pressed against the first door-shaped frame 101. When the rider pulls out or pushes back the push-pull block 301, the bottom surface of the support plate 302 slides along the top surface of the first protrusion 205. The height of the support plate 302 is greater than the height of the push-pull block 301, and the top surface of the support plate 302 is flush with the top surface of the push-pull block 301. Preferably, the distance between the bottom surface of the support plate 302 and the top surface of the second protrusion 206 is equal to the shell thickness of the top of the hook main body 1. When the hook cover 2 slides upward to the top of the hook main body 1, the second protrusion 206 is pressed against the top frame of the first door-shaped frame 101. At this time, the bottom surface of the support plate 302 is just flush with the top surface of the hook main body 1, so that the spring buckle 3 is smoothly pushed into the second bending section 402 of the bending part 4.

[0044] like Figure 3 As shown, one end of the first spring 6 is fixed to the blind hole 208, and the other end is fixed to the support plate 302 below the push-pull block 301. The first spring 6 is in a compressed state, pushing the spring buckle to resist the first door frame.

[0045] Example

[0046] The method of using the movable spring buckle 3 hook of the present invention is as follows:

[0047] When there are fewer items to be hung, the hook cover 2 does not need to slide out of the hook body 1. The items can be hung on the hook body 1 between the second bent section 402 and the hook cover 2, and the hook cover 2 forms a barrier.

[0048] When there are many items to be hung, the hook cover 2 above the hook body 1 cannot meet the needs. You can first hang some items on the hook body 1 between the second bending section 402 and the hook cover 2, and then hold the push-pull block 301 and pull the push-pull block 301 outward. The first spring 6 is squeezed, the limiting protrusion 103 exits the limiting hole 305, and pushes the push-pull block 301 upward. The push-pull block 301 moves upward along the slide bar 102 with the hook cover 2. When the second protrusion 206 presses against the top frame of the first door-shaped frame 101, the push-pull block 301 is pushed toward the bending portion 4. When the second bending section 402 and the spring block 502 gradually enter the positioning groove 303, the second spring When 501 is squeezed, the spring block 502 will gradually enter the positioning groove 303 through the inclined surface of the spring block 502 until the spring block 502 moves to the position of the locking groove 304. The second spring 501 releases its elastic force, pushing the spring block 502 to lock into the locking groove 304, locking the spring buckle 3. The locked spring buckle 3 prevents the hook cover 2 from sliding back to the hook body 1. At this time, the hook cover 2 above the spring buckle 3 can continue to hang items. The hook cover 2 slides upward along the hook body 1. The hook cover 2 can be used to hang items. The pre-placed items are hooked in the annular space surrounded by the bent portion 4, the spring buckle 3 and the hook body 1, thereby increasing the usable length of the hook cover 2.

[0049] When restoration is required, force is applied to the two levers 503 at the same time, the two levers 503 move closer to each other, the second spring 501 contracts, the two spring blocks 502 exit the slots 304, and after pulling the push-pull block 301 back outward, hold the push-pull block 301 and apply force downward, and the hook cover 2 slides downward along the slide bar 102 until the top frame of the second door-shaped frame 202 rests against the top frame of the first door-shaped frame 101.

[0050] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
