Description

Technical Field

[0001] This application belongs to the field of electric bicycle accessories, specifically relating to a movable spring-loaded hook. Background Technology

[0002] The back of the windshield of an electric bicycle is equipped with hooks for hanging items such as handbags, helmets, raincoats, and shopping bags. These hooks are threaded onto pre-drilled holes in the frame using bolts. There are many types of hooks, such as standard, concealed, and anti-theft hooks. Standard hooks are simple J- or L-shaped, directly connected to the frame without any special structural design. Concealed hooks pop out when pressed and are hidden in the vehicle when not in use. Anti-theft hooks utilize a unique structural design to prevent theft. However, existing hooks lack adjustable length, which is insufficient when multiple items need to be hung, presenting a drawback.

[0003] Chinese patent CN214565859U discloses a padlock hook for electric vehicles and motorcycles, including a lock hook and an upper hook. The lock hook is V-shaped and includes outer and inner clamping plates and an arc-shaped connecting plate connecting the lower ends of the outer and inner clamping plates. Several secondary hooks are provided on the outer wall of the outer clamping plate. The lock hook is used to attach an anti-theft lock, the upper hook is used to hang items or bags, and the secondary hooks are used to hang even more items or bags. This design allows for the hanging of more items by increasing the number of hooks. However, these hooks occupy a relatively large area, and because the secondary hooks protrude, riders are prone to touching them and scraping their knees. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a movable spring hook, which adjusts the length of the hook by spring to hang more items.

[0005] The technical solution adopted in this utility model is as follows:

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

[0007] Furthermore, the hook body is a shell with an opening on one side. The hook body can be a cuboid, for example, with a hollow cavity inside. A first gate-shaped frame is provided at the opening of the hook body. The width and height of the first gate-shaped frame are smaller than the width and height of the hook body. The two side frames of the first gate-shaped frame are respectively provided with outwardly protruding slides. The slides extend along the height direction of the first gate-shaped frame, forming a channel between the slides and the hook body. The top corners of the slides are rounded.

[0008] Furthermore, the top frame of the first portal frame is provided with two spaced-apart limiting protrusions, which protrude toward the hook cover. The hook body has a connecting hole on the side opposite to the opening, and the bolt passes through the connecting hole and connects to the frame.

[0009] Furthermore, the bent portion extends from the top of the hook body. The bent portion includes a first bent section connected to the top of the hook body and inclined to the hook body, and a second bent section integrally connected to the first bent section and parallel to the hook body. There is a certain distance between the second bent section and the hook cover. Items such as shopping bags or handbags are suspended on the hook body between the second bent section and the hook cover. The hook cover forms a barrier to prevent items from falling.

[0010] Furthermore, the second bending section has a through groove for setting a buckle, and one side of the through groove has two limiting ports that extend to the first bending section, with the two limiting ports spaced apart.

[0011] Furthermore, the latch includes a second spring, spring blocks connected to both ends of the second spring, and a lever fixedly connected to the spring blocks.

[0012] Furthermore, both spring blocks are right-angled trapezoids, with the plane containing the two long right-angled sides abutting the plane of the through groove away from the hook cover. The inclined surfaces of the two spring blocks are arranged in a figure-eight shape, and fixing holes for fixing the lever are opened on the side containing the two long right-angled sides. The second spring and part of the spring blocks are arranged in the cavity of the through groove, and the other part of the spring blocks extends out of the through groove. The plane containing the short straight side of the spring block is located in the through groove. The lever is L-shaped and includes a first rod inserted and fixed in the fixing hole and a second rod perpendicularly connected to the first rod. The first rod extends out through the limiting port and connects to the second rod. The first rod has a certain amount of room for movement within the limiting port. The lever is used to control the contraction and release of the second spring, thereby indirectly controlling the spring blocks. On the other hand, the lever is used to prevent the spring blocks from being ejected from the through groove.

[0013] Furthermore, the hook cover includes a main cover and a second portal frame disposed on the back of the main cover. The second portal frame surrounds the first portal frame. A sliding groove is formed on the side frame of the second portal frame, and a slide bar is arranged in the sliding groove. The sliding groove and the slide bar cooperate, and the hook cover slides up and down along the slide bar. The main cover inside the second portal frame has an opening for the spring clip to pass through. The opening is, for example, rectangular. A first protrusion supporting the spring clip is provided below the opening. A second protrusion is provided below the first protrusion. A clearance groove is provided on both sides of the first protrusion. The clearance groove is arranged along the length direction of the hook cover. During the upward sliding of the hook cover, the clearance groove is used to avoid the limiting protrusion. There is a gap between the second protrusion and the side frame of the second gate frame. The width of the second protrusion is less than the distance between the two limiting protrusions to avoid the limiting protrusions from hindering the assembly of the hook body and the hook cover. The protrusion height of the second protrusion relative to the main cover is greater than the protrusion height of the first protrusion relative to the main cover. The first protrusion does not protrude to the first gate frame, while the second protrusion protrudes to the first gate frame. The main cover between the first protrusion and the opening is provided with a blind hole for fixing the first spring.

[0014] Furthermore, the snap fastener includes a push-pull block extending outward from the opening and a stop plate disposed inside the hook cover and connected to the push-pull block. The shape of the push-pull block matches the shape of the opening. The push-pull block is, for example, a cuboid. Positioning grooves are formed on the push-pull block and the stop plate. A locking groove is formed on the side wall of the positioning groove. A limiting hole is formed on the top of the stop plate, with its position corresponding to the limiting protrusion. Under the elastic force of the first spring, the first spring pushes the snap fastener toward the hook body, and the limiting protrusion enters the limiting hole to prevent the rider from accidentally touching the hook cover upward, causing the hook cover to move along the hook body. The sliding plate abuts against the first gate-shaped frame. When the rider pulls out or pushes back the push-pull block, the bottom surface of the plate slides along the top surface of the first protrusion. The height of the plate is greater than the height of the push-pull block, and the top surface of the plate is flush with the top surface of the push-pull block. Preferably, the distance between the bottom surface of the 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 abuts against the top frame of the first gate-shaped frame. At this time, the bottom surface of the plate is exactly flush with the top surface of the hook body, so that the snap fastener can be smoothly pushed into the second bending section of the bending part.

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

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a movable spring-loaded hook. The hook body is connected to the bicycle frame. The hook body has a sliding strip, and the hook cover has a sliding groove. The hook cover slides up and down along the sliding strip. When the hook cover slides out of the hook body, the larger hook cover can be used to hang items, 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 spring pushes the spring-loaded hook towards the hook body, and a limiting protrusion enters a limiting hole to prevent the rider from accidentally touching the hook cover upwards, causing the hook cover to slide along the hook body. Slide the push-pull block outward. When the limiting protrusion exits the limiting hole, push the push-pull block upward. The push-pull block, along with the hook cover, moves upward along the slide bar, thus sliding the hook cover. By setting the bending part, 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. When the spring block moves to the position of the buckle groove, the second spring releases its elastic force, and the spring block is locked into the buckle groove, locking the spring buckle. The locked spring buckle prevents the hook cover from sliding back to the hook body 1. The hook cover above the spring buckle can continue to hang items without increasing the number of hooks, thus reducing the space occupied. Attached Figure Description

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] like Figure 1-9 As shown, a movable spring hook includes a hook body 1 connected to an electric bicycle frame, a hook cover 2 that slides longitudinally along the hook body 1, and a spring hook 3 that passes through the hook cover 2 and restricts the movement of the hook cover 2. The hook body 1 is provided with a bent part 4, which extends from the hook body 1 and bends toward the hook cover 2. The end of the bent part 4 is provided with a buckle 5 for engaging with the spring hook 3. A first spring 6 is provided between the hook cover 2 and the spring hook 3.

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 9 As shown, the hook body 1 is a shell with an opening on one side. The hook body 1 can be a cuboid, for example. The interior of the hook body 1 forms a hollow cavity. A first gate frame 101 is provided at the opening of the hook body 1. The width and height of the first gate frame 101 are smaller than the width and height of the hook body 1. The two side frames of the first gate frame 101 are respectively provided with outwardly protruding slides 102. The slides 102 extend along the height direction of the first gate frame 101, and a channel is formed between the slides and the hook body. The top corners of the slides are rounded.

[0037] like Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 9As shown, the top frame of the first portal frame 101 is provided with two spaced-apart limiting protrusions 103. The limiting protrusions 103 protrude toward the hook cover 2. The hook body 1 has a connecting hole on the side opposite to the opening. The bolt 7 passes through the connecting hole and is connected to the frame.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 As shown, the bent portion 4 extends from the top of the hook body 1. The bent portion 4 includes a first bent section 401 connected to the top of the hook body 1 and inclined to the hook body 1, and a second bent section 402 integrally connected to the first bent section 401 and parallel to the hook body 1. There is a certain distance between the second bent section 402 and the hook cover 2. Items such as shopping bags and handbags are suspended on the hook body between the second bent section 402 and the hook cover 2. The hook cover forms a barrier to prevent items from falling.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 As shown, the second bending section 402 has a through groove 403 for setting the buckle 5. On one side of the through groove 403, there are two limiting ports 404 that extend to the first bending section 401. The two limiting ports 404 are spaced apart.

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

[0041] like Figure 1 , Figure 2 , Figure 4 , Figure 9As shown, both spring blocks 502 are right-angled trapezoids, with the plane containing the two longer right-angled sides abutting against the plane of the through groove 403 away from the hook cover 2. The inclined surfaces of the two spring blocks 502 are arranged in a V-shape. Fixing holes 504 for fixing the lever 503 are opened on the side containing the two longer right-angled sides. The second spring 501 and part of the spring blocks 502 are arranged in the cavity of the through groove 403, and the other part of the spring blocks 502 extends out of the through groove 403. Preferably, the plane containing the shorter straight side of the spring block is located in the through groove. The lever 503 is L-shaped. The lever 503 includes a first lever 5031 inserted into and fixed in the fixing hole 504 and a second lever 5032 perpendicularly connected to the first lever 5031. The first lever 5031 extends out through the limiting port 404 and is connected to the second lever 5032. The first lever 5031 has a certain amount of room to move within the limiting port 404. 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 cover 201 and a second portal frame 202 disposed on the back of the main cover 201. The second portal frame 202 surrounds the first portal frame 101. A sliding groove 203 is opened on the side frame of the second portal frame 202. A slide bar 102 is arranged in the sliding groove 203. The sliding groove 203 cooperates with the slide bar 102. The hook cover 2 slides up and down along the slide bar 102. The main cover 201 inside the second portal frame 202 has 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. A clearance groove 207 is provided on both sides of the first protrusion 205. The clearance groove runs along the hook cover. Arranged along the length direction, during the upward sliding of the hook cover, the clearance groove is used to avoid the limiting protrusion. There is a gap between the second protrusion 206 and the side frame of the second gate 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 protrusions 103 from hindering the assembly of the hook body and the hook cover. The protrusion height of the second protrusion 206 relative to the main cover 201 is greater than the protrusion height of the first protrusion 205 relative to the main cover 201. The first protrusion 205 does not protrude to the first gate frame 101, while the second protrusion 206 protrudes to the first gate frame 101. The main cover 201 between the first protrusion 205 and the opening 204 is provided with a blind hole 208 for fixing the first spring 6.

[0043] like Figure 3 , Figure 8 , Figure 9As shown, the snap fastener 3 includes a push-pull block 301 extending outward through the opening 204 and a stop plate 302 disposed 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 cuboid. The push-pull block 301 and the stop plate 302 have positioning grooves 303. The side wall of the positioning groove 303 has a slot 304. The top of the stop plate 302 has a limiting hole 305 corresponding to the limiting protrusion 103. Under the elastic force of the first spring 6, the first spring 6 pushes the snap fastener 3 towards the hook body 1, and the limiting protrusion 103 enters the limiting hole 305 to prevent the rider from accidentally touching the hook cover 2 upwards, causing the hook cover 2 to move along the hook. The main body 1 slides, and the abutment plate 302 abuts against the first gate-shaped frame 101. When the rider pulls out or pushes back the push-pull block 301, the bottom surface of the abutment plate 302 slides along the top surface of the first protrusion 205. The height of the abutment plate 302 is greater than the height of the push-pull block 301. The top surface of the abutment plate 302 is flush with the top surface of the push-pull block 301. Preferably, the distance between the bottom surface of the abutment 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 abuts against the top frame of the first gate-shaped frame 101. At this time, the bottom surface of the abutment plate 302 is flush with the top surface of the hook main body 1, so that the snap 3 can be smoothly pushed into the second bent section 402 of the bent 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 abutment 302 below the push-pull block 301. The first spring 6 is in a compressed state, pushing the spring buckle against the first door frame.

[0045] Example

[0046] The following is a method of using a movable spring-loaded hook of this utility model:

[0047] When there are few items to be hung, the hook cover 2 does not need to slide out of the hook body 1. The items are hung on the hook body 1 between the second bend section 402 and the hook cover 2, and the hook cover 2 acts as an obstruction.

[0048] When there are many items to be hung, the hook cover 2 above the hook body 1 cannot meet the demand. First, some items can be hung between the second bend section 402 and the hook cover 2 on the hook body 1. Then, hold the push-pull block 301 and pull it outwards. The first spring 6 is compressed, the limiting protrusion 103 exits the limiting hole 305, and the push-pull block 301 is pushed upwards. The push-pull block 301, along with the hook cover 2, moves upwards along the slide bar 102. When the second protrusion 206 abuts against the top frame of the first door frame 101, the push-pull block 301 is pushed towards the bend section 4. As the second bend 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 slot 304. The second spring 501 releases its elastic force, pushing the spring block 502 into the slot 304 to lock 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 formed by the bend 4, the spring buckle 3, and the hook body 1, increasing the usable length of the hook cover 2.

[0049] When restoration is required, force is applied to both levers 503 simultaneously, causing them to move closer together. The second spring 501 contracts, and the two spring blocks 502 exit the slot 304. After pulling the push-pull block 301 outward, the push-pull block 301 is grasped and pushed downward. The hook cover 2 slides down along the slide bar 102 until the top frame of the second gate frame 202 abuts against the top frame of the first gate frame 101.

[0050] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
