Description

Technical Field

[0001] This invention relates to the field of quick-release and quick-install lock technology, and in particular to a quick-release and quick-install lock for bicycle baskets and its application. Background Technology

[0002] Some bicycles and e-bikes have baskets installed at the front handlebars to accommodate cargo.

[0003] However, traditional bicycle basket mounting brackets are cumbersome and difficult to install and remove, causing inconvenience to users. Moreover, the handlebar connection of existing bicycle basket mounting brackets is only compatible with handlebars of specific thicknesses, resulting in poor adaptability and versatility, and they also present the same problem of difficult installation and removal. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-release and quick-installation lock for bicycle baskets and its application. The quick-release and quick-installation lock can achieve quick disassembly of the bicycle basket by using an upward lifting unlocking and disassembly method. At the same time, the included angle of the V-shaped connector and the V-shaped connecting block at the handlebar connection end is an inferior angle, which can improve the installation compatibility of the bracket with different types of handlebars, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] On one hand, the present invention provides a quick-release and quick-install lock for a bicycle basket, comprising:

[0007] The mounting lock includes a first locking member and a second locking member. The first locking member includes a base and a positioning protrusion. The positioning protrusion is connected to the base via an elastic element and can extend towards the positioning side of the base under the action of the elastic element. The second locking member includes a base and a pull-type unlocking member. The base is used to slide vertically with the positioning side of the base. A locking positioning hole is provided on the side of the base facing the base. The pull-type unlocking member is slidably mounted on the base, and a lifting part is provided at the top of the pull-type unlocking member. Above the second base, the bottom of the pull-type unlocking component is provided with an unlocking part, and the bottom of the pull-type unlocking component is connected to the second base via an elastic element. The positioning protrusion can extend into the locking positioning hole after the second base and the first base are slidably installed in place, so that the second base and the first base are locked together. The pull-type unlocking component can be lifted under external force, so that the positioning protrusion is pushed out of the locking positioning hole by lifting the unlocking part, thereby unlocking the second base and the first base. The elastic element can automatically reset the pull-type unlocking component after the external force is removed. The second base is used to connect to a bicycle basket.

[0008] The handlebar connection includes a support base and a fixing base. The front side of the support base is connected to the base, and a V-shaped connector is provided on the rear side of the support base. The fixing base includes a V-shaped connecting block. The included angle between the V-shaped connecting block and the V-shaped connector is a minor angle. The openings of the V-shaped connecting block and the V-shaped connector are opposite each other. The two ends of the opening of the V-shaped connecting block are detachably connected to the two ends of the opening of the V-shaped connector through connecting screws. The V-shaped connecting block and the V-shaped connector are used to clamp and fix the handlebar.

[0009] In some embodiments, the included angle between the V-shaped connecting block and the V-shaped connector is 90° or both are obtuse angles.

[0010] In some implementations, the included angle between the V-shaped connecting block and the V-shaped connector is the same.

[0011] In some embodiments, the support base is a U-shaped support base, and the V-shaped connectors are provided at the ends of both side walls of the U-shaped support base; the openings of the V-shaped connectors face downwards, and each of the two ends of any V-shaped connector is provided with a connection hole.

[0012] The fixing base includes two V-shaped connecting blocks, the openings of which face upwards, and each V-shaped connecting block corresponds to a V-shaped connector. Both ends of the V-shaped connecting block are provided with internal thread structures for the connecting screw to be screwed in. The internal thread structure is a threaded hole opened in the V-shaped connecting block, or, both ends of the V-shaped connecting block are provided with a second connecting hole. The internal thread structure is a locking nut adapted to the connecting screw, and the locking nut is embedded in the second connecting hole through an anti-rotation structure.

[0013] In some embodiments, the mounting base further includes a support bridge, with two V-shaped connecting blocks respectively fixed to both ends of the support bridge; the support bridge is used to abut against the front side of the handlebar stem to provide upward support for the basket.

[0014] In some embodiments, the support bridge is a U-shaped support bridge, which is integrally formed with the two V-shaped connecting blocks.

[0015] In some embodiments, the base is a cavity substrate, the cavity substrate has a closed inner cavity, and the outer surface of the front end plate of the cavity substrate serves as the positioning side, and the front end plate is provided with a through hole for the positioning protrusion to extend and retract.

[0016] The positioning protrusion is located inside the closed inner cavity and is connected to the rear end plate of the cavity substrate through the elastic element. The positioning protrusion is a columnar protrusion arranged perpendicular to the cavity substrate. The front end of the columnar protrusion can extend to the outside of the through hole under the action of the elastic element. The rear end of the columnar protrusion is provided with a limiting platform protruding to the outer periphery of the columnar protrusion. The limiting platform can prevent the columnar protrusion from coming out forward from the closed inner cavity.

[0017] In some embodiments, the rear end plate is further provided with an outwardly protruding connecting portion, and the base is connected to the front side of the support base through the connecting portion.

[0018] In some embodiments, the second base is a cavity substrate, which has a closed inner cavity. The pull-type unlocking component is slidably installed in the closed inner cavity, and the pull portion extends to the top outside of the second base. The rear end plate of the second cavity substrate is used to be parallel to and attached to the front end plate of the first cavity substrate. The rear end plate of the second cavity substrate is provided with the locking positioning hole and a U-shaped groove with a downward opening. The U-shaped groove is located on the outer periphery of the locking positioning hole and protrudes from the outer surface of the rear end plate of the second cavity substrate. The U-shaped groove is used for the first base to slide upward or downward.

[0019] The front end plate of the cavity substrate is provided with longitudinal protrusions on both sides, and the top of the front end plate of the cavity substrate is provided with transverse protrusions. The two ends of the transverse protrusions are respectively connected to the two longitudinal protrusions, so as to form a U-shaped protrusion that is adapted to slide with the U-shaped groove on the outer periphery of the front end plate of the cavity substrate.

[0020] In some embodiments, the bottom of the pull-type unlocking component is further provided with a guide protrusion, and the rear end plate of the cavity substrate is provided with a guide groove. The guide groove is located below the locking positioning hole and communicates with the locking positioning hole. The guide protrusion and the guide groove are slidably installed.

[0021] The unlocking part is a wedge-shaped unlocking surface located on the top of the guide protrusion. The wedge-shaped unlocking surface can push the positioning protrusion out of the locking positioning hole when the lifting unlocking component is lifted.

[0022] In some embodiments, the top of the pull-type unlocking component is further provided with a guide protrusion 2, and the rear end plate of the cavity substrate 2 is provided with a guide groove 2. The guide groove 2 is located above the locking positioning hole and communicates with the locking positioning hole. The guide protrusion 2 and the guide groove 2 are slidably installed.

[0023] The second guide protrusion is spaced vertically from the first guide protrusion, and the space between them is used to accommodate the positioning protrusion.

[0024] In some embodiments, the cavity substrate two includes:

[0025] The front substrate shell has a front end plate that is the front end plate of the cavity substrate two. The outer peripheral sidewall of the front substrate shell has a plurality of nut positioning grooves, and the front and rear end faces of the front substrate shell have mounting holes that communicate with the nut positioning grooves. Nuts and nut positioning blocks are embedded in the nut positioning grooves. The nut positioning blocks are fastened to the nut positioning grooves by snap-fit, so as to press the nut against the bottom of the nut positioning groove and make the mounting holes on the front and rear end faces of the front substrate shell coaxially aligned with the nut.

[0026] The rear base plate shell is tightly fastened to the rear end face of the front base plate shell, and the rear base plate shell has countersunk holes corresponding to the nuts; the rear base plate shell is the rear end plate of the cavity base plate two.

[0027] An intermediate mounting base is disposed between the front base shell and the rear base shell, and the intermediate mounting base is snapped into the front base shell, forming the second closed inner cavity between the intermediate mounting base and the front base shell. The pull-type unlocking component is slidably mounted on the intermediate mounting base. The intermediate mounting base has through holes corresponding to the nuts.

[0028] The fastening screws correspond one-to-one with the nuts. The fastening screws pass through the countersunk holes and the through holes in sequence and are then tightened to the nuts to achieve a fast connection between the front base plate shell and the rear base plate shell.

[0029] In some embodiments, the lifting part is a closed lifting ring or a lifting hook.

[0030] On the other hand, the present invention proposes the application of the quick-release and quick-install lock of any of the above-mentioned bicycle baskets in the bicycle basket disassembly and assembly technology.

[0031] The present invention achieves the following technical effects compared to the prior art:

[0032] The quick-release and quick-install lock for bicycle baskets proposed in this invention uses a pull-type unlocking mechanism. By lifting the pull-type unlocking mechanism with external force, the unlocking part of the mechanism pushes the positioning protrusion back, achieving quick unlocking and disassembly. When applied to the disassembly and assembly of bicycle baskets, the quick-release and quick-install lock, based on the pull-type unlocking method of the lock, provides an upward lifting force to the basket during and after unlocking, enabling effortless disassembly. It can be completed with one hand, making it convenient and quick. This solves the technical problem of existing bicycle basket disassembly and assembly structures, where the increased weight and contents of the basket make quick unlocking and disassembly difficult.

[0033] The quick-release and quick-install lock for the bicycle basket uses a sliding disassembly and assembly mechanism between the two locking parts, which can meet the needs of quick disassembly and quick assembly. Compared with the existing disassembly and assembly structure, it has the advantages of ingenious structure, simple components, reliable performance and easy operation.

[0034] Because handlebar diameters vary, existing bicycle basket brackets typically use multiple bushings of different sizes to address this issue. However, the quick-release and quick-install lock proposed in this invention uses a V-shaped connecting block and a V-shaped connector opening to clamp the handlebar at the connection end. The included angle between the V-shaped connecting block and the V-shaped connector is a minor angle, eliminating the need for bushings. This design allows for compatibility with different types and diameters of handlebars, improving the quick-release and quick-install lock's compatibility with various handlebar types.

[0035] Furthermore, the V-shaped connecting block and V-connector at the handlebar connection end are connected by a connecting screw. The spacing between the V-shaped connecting block and V-connector can be adjusted by changing the depth of the connecting screw into the internal thread of the V-shaped connecting block. This allows the handlebar connection end to accommodate different types and thicknesses of handlebars without the need for bushings, thus improving the versatility and adaptability of the quick-release and quick-install lock mechanism for the bicycle basket. At the same time, using a connecting screw to connect the V-shaped connecting block and V-connector facilitates disassembly and assembly, enhancing the ease of bracket assembly and disassembly. Compared to existing bushing installation methods, this simplifies the number of parts, resulting in cost reduction and efficiency improvement.

[0036] In some technical solutions disclosed in this invention, the V-type connector and the V-type connecting block are arranged vertically. The connecting screw passes through the connecting hole one of the V-type connector from the top and enters the connecting hole two of the V-type connecting block, and is tightened with the internal thread structure in the V-type connecting block to achieve a tight connection between the V-type connector and the V-type connecting block. In this structure, the connecting screw is arranged in the vertical direction, which can reduce the contact opportunity between the bicycle and the connecting screw and ensure the reliability and durability of the connection between the V-type connector and the V-type connecting block.

[0037] In some of the technical solutions disclosed in this invention, a support bridge is connected between the two V-shaped connecting blocks of the fixed base. On the one hand, this achieves structural integration of the two V-shaped connecting blocks. During the disassembly or installation of the bracket, a single person can support the support bridge with one hand to install or disassemble the two V-shaped connecting blocks, saving manpower and preventing the V-shaped connecting blocks from falling off during disassembly and assembly, thus improving the efficiency of disassembly and assembly of the two V-shaped connecting blocks. On the other hand, when the support bridge is installed, it is used to abut against the front side of the handlebar stem tube to prevent the entire basket quick-release lock from sagging, providing upward support for the basket and preventing the handlebar connection end from rotating forward and downward relative to the handlebar due to the weight of the basket. This improves the support strength of the bracket for the basket and also enhances the load-bearing capacity of the basket.

[0038] In some of the technical solutions disclosed in this invention, the threaded hole structure of the front base plate shell for connecting with the fastening screw adopts a detachable structure design. That is, the front base plate shell with a nut positioning groove is integrally formed first, and then the nut and nut positioning block are assembled into the nut positioning groove. Compared with the process of directly machining the threaded hole on the front base plate shell, the assembly design of the front base plate shell and the nut in this invention can simplify the production process of the front base plate shell and reduce the production cost of the front base plate shell. When the nut is damaged, only the nut that needs to be replaced needs to be removed, without replacing the entire front base plate shell, thus reducing the maintenance cost of the front base plate shell.

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] The purpose of this invention is to provide a quick-release and quick-installation lock for bicycle baskets and its application. The quick-release and quick-installation lock can achieve quick disassembly of the bicycle basket by using an upward lifting unlocking and disassembly method. At the same time, the included angle of the V-shaped connector and the V-shaped connecting block at the handlebar connection end is an inferior angle, which can improve the installation compatibility of the bracket with different types of handlebars, thereby solving the problems existing in the prior art.

[0066] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0067] Example 1

[0068] like Figure 1 and Figure 2 As shown, this embodiment provides a quick-release and quick-install lock for a bicycle basket, including a lock mounting part 200 and a handlebar connecting end 300.

[0069] like Figure 3 and Figure 4As shown, the mounting lock 200 includes a first locking member 1 and a second locking member 2. The first locking member 1 and the second locking member 2 are respectively used to install on two parts to be connected. For example, the first locking member 1 and the second locking member 2 are respectively connected to the basket and the handlebar connection end 300 (the handlebar connection end 300 is used to connect the handlebars), which can be used for quick removal and quick installation of the basket on the handlebars. Figures 6-9 As shown, the first locking member 1 includes a base 11 and a positioning protrusion 12. The positioning protrusion 12 is connected to the base 11 through an elastic member 13. The positioning protrusion 12 can extend towards the positioning side of the base 11 under the action of the elastic member 13. The second locking member 2 includes a base 21 and a pull-type unlocking member 22. The base 21 is used to slide up and down with the positioning side of the base 11. A locking positioning hole 212 is provided on the side of the base 21 facing the base 11. The pull-type unlocking member 22 is slidably installed on the base 21. The top of the pull-type unlocking member 22 is provided with a lifting part 221. The lifting part 221 is located above the base 21, making it easy for people to find and lift it. The bottom of the pull-type unlocking member 22 is provided with an unlocking part 222. The bottom of the pull-type unlocking member 22 is connected to the base 21 through an elastic member 23. After the base 21 and base 11 are slidably installed in place, the positioning protrusion 12 automatically extends into the locking positioning hole 212 under the action of the elastic element 13. Through the interlocking of the locking positioning hole 212 and the positioning protrusion 12, and the circumferential limiting effect of the locking positioning hole 212 on the positioning protrusion 12, the locking connection between the base 21 and base 11 is realized. The lifting unlocking part 22 can be lifted relative to the base 21 under the action of external force (such as the upward lifting force applied by a person to the lifting part 221). Then, by lifting the unlocking part 222, the positioning protrusion 12 is pushed out of the locking positioning hole 212. At this time, the locking positioning hole 212 and the positioning protrusion 12 are separated from each other, and the unlocking purpose is achieved. Afterwards, by continuing to lift the above-mentioned lifting unlocking part 22, the entire base 21 can be slid relative to the base 11 until the base 21 slides off the base 11, realizing the unlocking separation of the base 21 and base 11. Afterwards, the elastic element 23 can automatically reset the pull-type unlocking element 22 after the external force is removed. After resetting, the unlocking part 222 returns to the bottom of the locking positioning hole 212. The locking positioning hole 212 is unobstructed, allowing the positioning protrusion 12 to be directly inserted, thus achieving re-locking installation.

[0070] like Figures 1-3As shown, the handlebar connection end 300 includes a support base 4 and a fixing base 5. The front side of the support base 4 is connected to the base 11, and the rear side of the support base 4 is provided with a V-shaped connector 41. The fixing base 5 includes a V-shaped connecting block 51. The included angle between the V-shaped connecting block 51 and the V-shaped connector 41 is an obtuse angle (an obtuse angle is a geometric term that refers to an angle greater than 0° and less than 180°, including acute angles, right angles and obtuse angles). For example, the included angle between the V-shaped connecting block 51 and the V-shaped connector 41 is 90° or both are obtuse angles. When it is an obtuse angle, 120°~160° is preferred. The openings of the V-shaped connecting block 51 and the V-shaped connector 41 are arranged opposite to each other, and the two ends of the opening of the V-shaped connecting block 51 are detachably connected to the two ends of the opening of the V-shaped connector 41 through the connecting screw 6. The V-shaped connecting block 51 and the V-shaped connector 41 are used to clamp and fix the handlebar. By tightening the connecting screw 6, both the V-shaped connecting block 51 and the V-shaped connector 41 can clamp the handlebar, thereby achieving a tight connection between the handlebar connecting end 300 and the handlebar. If it is necessary to remove the handlebar connecting end 300, unscrew the connecting screw 6, and separate the fixing seat 5 and the V-shaped connector 41.

[0071] In some feasible embodiments, the support base 4 is preferably a U-shaped support base, with the opening of the U-shaped support base facing the rear side, and V-shaped connectors 41 are provided at the ends of both side walls of the U-shaped support base, with the openings of the V-shaped connectors 41 facing downwards. Figure 2 and Figure 3 As shown, each V-connector 41 has a connecting hole 42 at both its front and rear ends. The connecting hole 42 is preferably a through hole, and each connecting hole 42 has a countersunk groove at its top for accommodating the head of the connecting screw 6. Correspondingly, the fixing base 5 includes two V-connecting blocks 51, with the opening of each V-connecting block 51 facing upwards. Each V-connecting block 51 corresponds one-to-one with a V-connector 41. Both the front and rear ends of the V-connecting block 51 are provided with internal thread structures for screwing the connecting screw 6. The internal thread structure can be a threaded hole opened within the V-connecting block 51, or, as... Figures 2-4 As shown, the V-shaped connecting block 51 has connecting holes 53 at both its front and rear ends. The internal thread structure is a locking nut 54 adapted to the thread of the connecting screw 6. The locking nut 54 can be inserted into the connecting hole 53 through the anti-rotation structure 55. Figure 4 As shown, the anti-rotation structure 55 is preferably a regular hexagonal hole adapted to the outer contour of the locking nut 54. The locking nut 54 is fitted into the regular hexagonal hole with a clearance or interference fit. The connecting screw 6 can be a bolt, which passes through the first connecting hole 42 from above and extends downward into the corresponding second connecting hole 53, and is tightened with the thread of the locking nut 54 fitted into the regular hexagonal hole. During the process of screwing the connecting screw 6 into the locking nut 54, the locking nut 54 remains stationary due to the limiting effect of the regular hexagonal hole. The locking nut 54 is preferably welded into the regular hexagonal hole.

[0072] The V-connector 41 and V-connecting block 51 are arranged vertically. The connecting screw 6 passes through the connecting hole 42 of the V-connector from the top and then enters the connecting hole 52 of the V-connecting block 51, where it is tightened with the locking nut 54, thus achieving a secure connection between the V-connector 41 and the V-connecting block 51. In this structure, the connecting screw 6 is arranged vertically, which reduces the chance of contact between the bicycle and the connecting screw 6, ensuring the reliability and durability of the connection between the V-connector 41 and the V-connecting block 51. At the same time, the connecting screw 6 passes through from top to bottom, which provides more operating space compared to passing through the front and rear sides of the handlebars, making the assembly and disassembly of the connecting screw 6 simpler and easier.

[0073] In practical applications, when the bracket is installed on handlebars of different specifications and thicknesses, the distance between the V-shaped connecting block 51 and the V-shaped connector 41 is also different. Correspondingly, the depth to which the connecting screw 6 extends into the connecting hole 53 is also different, in order to adapt to handlebars of different specifications and thicknesses.

[0074] In some feasible implementations, the mounting base 5 also includes a support bridge 52, with two V-shaped connecting blocks 51 fixed to both ends of the support bridge 52 respectively. During installation, after the V-shaped connector 41 of the support base 4 is aligned vertically with the V-shaped connecting block 51 of the mounting base 5, the support bridge 52 is located on the front side of the handlebar stem. After the V-shaped connector 41 of the support base 4 and the V-shaped connecting block 51 of the mounting base 5 are connected and tightened by the connecting screw 6, the support bridge 52 is exactly against the front side of the handlebar stem to restrict the handlebar connection end 300 from rotating downward relative to the handlebar, preventing the bracket from sagging as a whole, and providing upward support for the basket. This support includes at least one of vertical upward support and oblique upward support. A support bridge 52 is connected between the two V-shaped connecting blocks 51 of the fixed base 5. On the one hand, it realizes the structural integration of the two V-shaped connecting blocks 51. During the disassembly or installation of the bracket, a single person can support the support bridge 52 with one hand to install or disassemble the two V-shaped connecting blocks 51, saving manpower and preventing the V-shaped connecting blocks 51 from falling off during disassembly and assembly, thus improving the efficiency of disassembly and assembly of the two V-shaped connecting blocks 51. On the other hand, when the support bridge 52 is installed, it is used to abut against the front side of the handlebar stem tube to prevent the bracket from sagging. It can also prevent the handlebar connecting end 300 from rotating forward and downward relative to the handlebar due to the weight of the basket, thereby improving the support strength of the bracket for the basket and also increasing the load-bearing capacity of the basket.

[0075] Some feasible implementation methods, such as Figure 3 and Figure 4 As shown, the support bridge 52 is preferably a one-piece molded U-shaped support bridge, and the U-shaped support bridge and the two V-shaped connecting blocks 51 are preferably one-piece molded to improve the overall structural strength of the fixing seat 5. One-piece molding can also simplify the processing technology of the fixing seat 5 and reduce its processing cost.

[0076] In some feasible embodiments, to facilitate the connection between the base 11 and the front side of the support 4, it is preferable that the rear end plate of the base 11 is also provided with an outwardly protruding connecting part 3, and the connecting part 3 is preferably made of... Figure 6 and Figure 8 The hanging ear structure is shown. In practical applications, the connecting part 3 can also adopt other forms of mounting structure such as a mounting plate or mounting rod. Correspondingly, another connecting part is provided on the front side of the support base 4, such as... Figure 2 and Figure 3 As shown, after the connecting part of the support base 4 and the connecting part 3 of the base 11 are aligned, a bolt rod passes through and is tightened to fix them. Loosening the bolt rod allows adjustment of the relative posture between the base 11 and the support base 4. After adjustment, tightening the bolt rod again fixes the relative position of the base 11 and the support base 4.

[0077] Some feasible implementation methods, such as Figures 5-8 As shown, base 11 is a cavity substrate 1, which has a closed inner cavity 111 inside. The outer surface of the front end plate of the cavity substrate 1 serves as the aforementioned positioning side. The positioning side is flat, which facilitates the guiding and positioning of base 11 and base 21 during sliding assembly and disassembly. A through hole 112 for the positioning protrusion 12 to extend and retract is provided on the front end plate of the cavity substrate 1. The positioning protrusion 12 is located in the closed inner cavity 111 and is connected to the rear end plate of the cavity substrate 1 (arranged opposite to the aforementioned front end plate) through an elastic member 13. The front end of the positioning protrusion 12 can extend to the outside of the through hole 112 under the action of the elastic member 13, so as to be inserted and positioned with the locking positioning hole 212.

[0078] In some feasible embodiments, the positioning protrusion 12 is a columnar protrusion arranged perpendicular to the cavity substrate. The rear end of the columnar protrusion is provided with a limiting platform 121 protruding outward from the outer periphery of the columnar protrusion. The limiting platform 121 can prevent the columnar protrusion from coming out forward from the closed inner cavity 111, and at the same time limit the depth of the positioning protrusion 12 inserted into the locking positioning hole 212, thereby improving the reliability of the entire basket quick-release and quick-install lock 100.

[0079] In some feasible embodiments, the positioning protrusion 12 includes, but is not limited to, cylindrical or prismatic protrusions (such as triangular or quadrangular prisms). The shapes of the through hole 112 and the locking positioning hole 212 are preferably adapted to the cross-sectional shape of the positioning protrusion 12 to ensure that the through hole 112 and the locking positioning hole 212 can effectively limit the circumferential positioning of the positioning protrusion 12. As a preferred embodiment, such as... Figures 9-11 As shown, the positioning protrusion 12 is preferably a cylindrical protrusion, and the through hole 112 and the locking positioning hole 212 are preferably circular holes with the same diameter as the outer diameter of the cylindrical protrusion.

[0080] In some feasible embodiments, the second base 21 is a cavity substrate 2, which has a closed inner cavity 211. A pull-type unlocking component 22 is slidably installed within the closed inner cavity 211, and the pull-out portion 221 extends to the top outside of the second base 21. The rear end plate of the second cavity substrate faces the front end plate of the first cavity substrate and is used to parallelly engage with the front end plate of the first cavity substrate. During the sliding assembly and disassembly of the second base 21 relative to the first base 11, the rear end plate of the second cavity substrate and the front end plate of the first cavity substrate remain parallel, with a clearance sliding fit between them. The rear end plate of the second cavity substrate is provided with a locking positioning hole 212 and a downward-facing U-shaped groove 213, allowing the second cavity substrate to adopt... Figure 5 and Figure 9 Taking the rectangular plate shape shown as an example, the locking and positioning hole 212 is preferably located at the center of the cavity substrate 2, and the U-shaped groove 213 is located on the outer periphery of the locking and positioning hole 212 and protrudes from the outer surface of the rear end plate of the cavity substrate 2. The U-shaped groove 213 is used for the base 11 to slide upward or downward. Correspondingly, longitudinal protrusions 113 that slide and adapt to the U-shaped groove 213 are provided on both sides of the front end plate of the cavity substrate 1. The longitudinal protrusions 113 are preferably continuous strip-shaped protrusions.

[0081] In some feasible implementations, to ensure accurate positioning between base 11 and base 21 after they are slidably installed in place, a transverse protrusion 114 is preferably provided on the top of the front end plate of the cavity substrate 1. Figures 6-8 As shown, the two ends of the transverse protrusion 114 are respectively connected to the two longitudinal protrusions 113 to form a U-shaped protrusion on the outer periphery of the front end plate of the cavity substrate 1. After the base 11 and the base 21 are slidably installed in place, the transverse protrusion 114 is embedded in the top groove of the aforementioned U-shaped groove 213.

[0082] To facilitate processing, a closed annular protrusion can be directly provided on the outer periphery of the front end plate of the cavity substrate. The part of the annular protrusion except for the bottom protrusion is the aforementioned U-shaped protrusion.

[0083] In some feasible implementations, the bottom of the pull-type unlocking component 22 is also provided with a guide protrusion 223, and a guide groove 214 is provided on the rear end plate of the cavity base plate 2. The guide groove 214 is located below the locking positioning hole 212 and communicates with the locking positioning hole 212. The guide protrusion 223 and the guide groove 214 are slidably installed. During the lifting and resetting process of the pull-type unlocking component 22, the sliding cooperation between the guide protrusion 223 and the guide groove 214 can provide a good guiding effect for the pull-type unlocking component 22, avoid the pull-type unlocking component 22 from shifting during the lifting and resetting process, thereby causing damage, and improve the reliability of the quick-release and quick-install lock of the basket.

[0084] Based on the arrangement of the guide protrusion 223 and guide groove 214, the unlocking part 222 is preferably a wedge unlocking surface provided on the top of the guide protrusion 223. The wedge unlocking surface can utilize the slope characteristics of the wedge plane to slide and cooperate with the front end of the positioning protrusion 12 when the lifting unlocking part 22 is lifted. Then, by utilizing the change in the position of the wedge surface, the positioning protrusion 12 is pushed to the outside of the locking positioning hole 212 to achieve the unlocking purpose.

[0085] In some feasible implementations, the top of the pull-out unlocking component 22 is also provided with a second guide protrusion 224, and a second guide groove 215 is provided on the rear end plate of the cavity base plate 2. The second guide groove 215 is located above the locking positioning hole 212 and communicates with the locking positioning hole 212. The second guide protrusion 224 and the second guide groove 215 are slidably installed. During the lifting and resetting process of the pull-out unlocking component 22, the second guide protrusion 224 and the second guide groove 215 slide together, which can assist the first guide protrusion 223 and the first guide groove 214 to provide a good guiding effect for the pull-out unlocking component 22, avoid the pull-out unlocking component 22 from shifting during the lifting and resetting process, thereby causing damage, and further improve the reliability of the quick-release and quick-install lock of the basket.

[0086] The aforementioned guide protrusion 224 is parallel to and vertically aligned with guide protrusion 223. Correspondingly, guide groove 215 is parallel to and vertically aligned with guide groove 214. Guide protrusion 224 and guide protrusion 223 are spaced vertically apart, and the space between them is used to accommodate the positioning protrusion 12.

[0087] In some embodiments, the cavity substrate two (i.e., base two 21) includes a front substrate shell 216, a rear substrate shell 217, a middle mounting substrate 218, and a fastening screw 219. For example... Figures 12-17As shown, the front end face of the front substrate shell 216 is the front end plate of the cavity substrate two. Multiple nut positioning grooves 2161 are formed on the outer peripheral sidewall of the front substrate shell 216, and mounting holes 2162 communicating with the nut positioning grooves 2161 are formed on both the front and rear end faces of the front substrate shell 216. Nuts 2163 and nut positioning blocks 2164 are embedded in the nut positioning grooves 2161. The nut positioning blocks 2162 are snapped into the sidewall of the nut positioning grooves 2161 by a snap fastener, so that the nuts 2163 are pressed against the bottom of the nut positioning grooves 2161, and the mounting holes 2162 on the front and rear end faces of the front substrate shell 216 are coaxially aligned with the nuts 2163. The rear substrate shell 217 is tightly fastened to the rear end face of the front substrate shell 216, and countersunk holes 2171 corresponding one-to-one with the nuts 2163 are formed on the rear substrate shell 217; the rear substrate shell 217 is the rear end plate of the cavity substrate two. An intermediate mounting base plate 218 is disposed between the front base plate shell 216 and the rear base plate shell 217, and the intermediate mounting base plate 218 is snapped into the front base plate shell 216, forming a closed inner cavity 211 between the intermediate mounting base plate 218 and the front base plate shell 216. A pull-type unlocking member 22 is slidably mounted on the intermediate mounting base plate 218. The intermediate mounting base plate 218 has through holes 2181 corresponding to the nuts 2163. Fastening screws 219 correspond to the nuts 2163. The fastening screws 219 pass through the countersunk holes 2171 and the through holes 2181 in sequence and are screwed into the nuts 2163 to achieve a fast connection between the front base plate shell 216 and the rear base plate shell 217.

[0088] Some feasible implementation methods, such as Figures 12-17 As shown, preferably, a nut positioning groove 2161 is provided at each of the four corners of the front base plate shell 216, and the four nut positioning grooves 2161 are arranged symmetrically in two groups, with two nut positioning grooves 2161 in each group being horizontally aligned. After the nut positioning block 2164 is engaged with the nut positioning groove 2161, the outer end face of the nut positioning block 2164 is flush with the outer peripheral sidewall of the front base plate shell 216. Based on the above structure, an "internal threaded hole structure" is formed at the four corners of the front base plate shell 216, which can improve the connection reliability and stability of the front and rear base plate shells.

[0089] In some feasible implementations, the lifting part 221 may be a closed lifting ring or a lifting hook.

[0090] In some feasible implementations, both the aforementioned elastic element 13 and elastic element 23 are preferably springs.

[0091] The following section uses the application of the aforementioned quick-release and quick-install lock 100 for bicycle baskets in bicycle basket assembly and disassembly technology as an example to explain the working principle of the aforementioned quick-release and quick-install lock 100 for bicycle baskets.

[0092] The first locking component 1 is connected to the basket, and the second locking component is fastened to the front handlebars of an automatic or electric bicycle via the handlebar connection end 300.

[0093] During installation, hold the basket and slide the U-shaped groove 213 of base 21 from top to bottom onto the outside of the U-shaped protrusion of base 11. After sliding into place, the positioning protrusion 12 extends into the locking positioning hole 212 to achieve a locking connection between base 21 and base 11, thereby completing the quick installation of the basket on the front handlebars.

[0094] When the basket needs to be disassembled, the person holds the lifting part 221 of the pull-type unlocking component 22 and pulls it upwards. This lifts the wedge unlocking surface, pushing the positioning protrusion 12 out of the locking positioning hole 212, thus achieving quick unlocking. During this process, lifting the aforementioned pull-type unlocking component 22 applies a certain lifting force to the basket, preventing disassembly difficulties caused by the basket being loaded with items or being heavy.

[0095] The quick-release and quick-install lock for bicycle baskets proposed in this invention employs a lifting unlocking structure. By utilizing the lifting movement of the wedge-shaped unlocking surface, the positioning protrusion is pushed back, achieving rapid unlocking and disassembly. Furthermore, the lifting operation provides an upward pulling force to the basket during and after unlocking, allowing for quick and convenient disassembly with just one hand. When installing the basket, simply align it with the U-shaped groove 213 and the U-shaped protrusion, then lower the basket to quickly complete the locking installation.

[0096] This invention enables the sliding assembly and disassembly of the bicycle basket, meeting the needs for quick assembly and disassembly, and allowing for effortless disassembly with just one hand. Compared to existing bicycle basket assembly and disassembly structures, this invention has the advantages of ingenious structure, simple components, reliable performance, and easy operation.

[0097] The quick-release and quick-install lock for the bicycle basket uses a sliding disassembly and assembly mechanism between the two locking parts, which can meet the needs of quick disassembly and quick assembly. Compared with the existing disassembly and assembly structure, it has the advantages of ingenious structure, simple components, reliable performance and easy operation.

[0098] The quick-release and quick-install lock for bicycle baskets proposed in this invention uses a connecting block and a V-shaped connector to clamp the handlebars at the handlebar connection end. The included angles of the connecting block and the V-shaped connector are both minor angles, such as obtuse angles, so that it can be adapted to be installed on different types and thicknesses of handlebars, thereby improving the compatibility of the quick-release and quick-install lock for bicycle baskets with different types of handlebars.

[0099] In addition, the connecting block and V-connector at the handlebar connection end are connected by a connecting screw. The spacing between the connecting block and the V-connector can be adjusted by adjusting the depth of the connecting screw into the connecting hole of the V-connector, so that the handlebar connection end can clamp handlebars of different types and thicknesses, further improving the versatility and adaptability of the quick-release and quick-install lock for the basket.

[0100] In the mounting lock 200 disclosed in this invention, the threaded hole structure of the front base plate shell for connecting with the fastening screw adopts a detachable structure design. That is, the front base plate shell with a nut positioning groove is integrally formed first, and then the nut and nut positioning block are assembled into the nut positioning groove. Compared with the process of directly machining the threaded hole on the front base plate shell, the assembly design of the front base plate shell and the nut in this invention can simplify the production process of the front base plate shell and reduce the production cost of the front base plate shell. When the nut is damaged, only the nut that needs to be replaced needs to be removed, without replacing the entire front base plate shell, thus reducing the maintenance cost of the front base plate shell.

[0101] Example 2

[0102] This embodiment proposes the application of the quick-release and quick-install lock 100 for bicycle baskets in embodiment 1 in bicycle basket disassembly and assembly technology. The quick-release and quick-install lock 100 enables the disassembly and assembly of the bicycle basket, meeting the need for quick disassembly and quick assembly of the basket on the front handlebars. Even if the basket is loaded with items, the unique lifting unlocking structure of the lock in the quick-release and quick-install lock 100 can provide an upward lifting force for the basket, enabling effortless disassembly. It can be completed with one hand, making it convenient and quick.

[0103] The handlebar connector 300 uses the V-shaped connector 51 and the V-shaped connector 41 to clamp the handlebar by connecting their openings. The included angles of the V-shaped connector 51 and the V-shaped connector 41 are both minor angles, such as obtuse angles, so that they can be adapted to be installed on different types and thicknesses of handlebars, which can improve the compatibility of the quick-release lock of the basket with different types of handlebars.

[0104] Furthermore, the V-shaped connecting block 51 and V-shaped connector 41 of the handlebar connection end 300 are connected by a connecting screw 6. The spacing between the V-shaped connecting block 51 and V-shaped connector 41 can be adjusted by changing the depth of the connecting screw 6 into the internal thread structure of the V-shaped connecting block. This allows the handlebar connection end to clamp handlebars of different types and thicknesses, further improving the versatility and adaptability of the quick-release and quick-install lock for the bicycle basket. At the same time, using the connecting screw 6 to connect the V-shaped connecting block 51 and V-shaped connector 41 facilitates disassembly and assembly, enhancing the ease of mounting and disassembly of the bracket.

[0105] The V-connector 41 and V-connecting block 51 are arranged vertically. The connecting screw 6 passes through the connecting hole 42 of the V-connector from the top and then enters the connecting hole 52 of the V-connecting block 51, where it is tightened with the locking nut 54, thus achieving a secure connection between the V-connector 41 and the V-connecting block 51. In this structure, the connecting screw 6 is arranged vertically, which reduces the chance of contact between the bicycle and the connecting screw 6, ensuring the reliability and durability of the connection between the V-connector 41 and the V-connecting block 51. At the same time, the connecting screw 6 passes through from top to bottom, which provides more operating space compared to passing through the front and rear sides of the handlebars, making the assembly and disassembly of the connecting screw 6 simpler and easier.

[0106] A support bridge 52 is connected between the two V-shaped connecting blocks 51 of the fixing seat 5 in the handlebar connection end 300. On the one hand, it realizes the structural integration of the two V-shaped connecting blocks 51. During the disassembly or installation of the bracket, a single person can support the support bridge 52 with one hand to install or disassemble the two V-shaped connecting blocks 51, saving manpower and preventing the V-shaped connecting blocks 51 from falling off during disassembly and installation, thus improving the efficiency of disassembly and installation of the two V-shaped connecting blocks 51. On the other hand, when the support bridge 52 is installed, it is used to abut against the front side of the handlebar stem tube, which can prevent the handlebar connection end 300 from rotating forward and downward relative to the handlebar due to the weight of the basket, thus preventing the bracket from sagging, improving the support strength of the bracket for the basket, and also increasing the load-bearing capacity of the basket.

[0107] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
