Description

Technical Field

[0001] The utility model relates to the field of bicycle connecting seats, in particular to a simple bicycle connecting seat with a stable locking function. Background Art

[0002] A common method of fixing a bicycle bag to a bicycle is to pre-set a mounting position on the bicycle and detachably mount the bicycle bag on the mounting position.

[0003] Although traditional technology can secure a bike bag, it fixes a bulky and heavy connector on the surface of the bag, causing a large protrusion on the bag's surface, affecting the bag's original appearance. When holding the bag by hand or holding it under the arm, the second connector will hurt the hand. When carrying a backpack, the second connector will also hurt the side of the body, affecting people's user experience.

[0004] The applicant has developed a bicycle connector and bicycle hook assembly, wherein the bicycle connector includes a connector body, the connector body including a first mounting portion and a hook portion connected to the front side of the first mounting portion; the first mounting portion is used to be mounted on a bicycle; the front end of the hook portion has a slot extending vertically and extending through the front and rear sides thereof, and the slot at least extends upward through the top of the hook portion to form a latching entrance; the front and rear sides of the slot have front and rear retaining walls; and the left and right ends of the hook portion are formed with a left end beveled portion and a right end beveled portion that expand outward from top to bottom. In this way, the bicycle connector combines the connection functions of two types of buckles and has excellent versatility. In particular, the slot is suitable for the clamping portion of the first buckle. The first buckle structure is generally flat. When installed on a bag body, it does not affect the appearance of the bag, does not hurt the hand, and does not affect the user experience when holding the bag, clipping the bag, or carrying a backpack.

[0005] Based on this, the applicant further researched and designed the bicycle connecting seat to make the structure simpler and the operation more convenient; in addition, the auxiliary locking part of the original bicycle connecting seat is set near the bottom, which means that the buckle has to extend to the bottom position. If the height dimension of the buckle is designed to be smaller, the buckle will not be able to extend to the bottom position and cannot form a locking relationship with the auxiliary locking part. Further research on new technical solutions is also needed to solve this problem. Utility Model Content

[0031] A simple bicycle connector 100 with a secure locking mechanism includes a connector body 10 for mounting on a bicycle (typically, on a tube 400). The connector body 10 includes a first mounting portion 11 and a hook portion 12 connected to the front side of the first mounting portion 11. The first mounting portion 11 includes an upper connecting arm 111, a lower connecting arm 112, and a mounting arm 113. The mounting arm 113 is used for mounting on a bicycle, for example, by screw-locking mounting. The rear ends of the upper connecting arm 111 and the lower connecting arm 112 are respectively connected to the upper and lower ends of the mounting arm 113, and the front ends of the upper connecting arm 111 and the lower connecting arm 112 are respectively connected to the rear end of the hook portion 12, and the front end of the upper connecting arm 111 is located above the front end of the lower connecting arm 112. An air avoidance operation area 14 is formed between the upper connecting arm 111, the mounting arm 113, the lower connecting arm 112 and the rear end of the hook portion 12; the front side of the air avoidance operation area 14 is open, and the left side and / or right side of the air avoidance operation area 14 are open. Preferably, the left side and right side of the air avoidance operation area 14 are open to facilitate the user's fingers to enter for operation.

[0032] The upper connecting arm 111 is connected to an elastic locking arm 13 ; the elastic locking arm 13 may be an integrally formed plastic part. The elastic locking arm 13 includes an arm fixing end 131, an arm elastic section 132 and an arm body 133 connected in sequence from top to bottom, the front side of the arm body 133 is provided with a locking protrusion 1331 protruding forward, and the rear side of the arm body 133 is provided with an unlocking pull-up portion 1332 protruding backward; the arm fixing end 131 is connected to the upper connecting arm 111, and the upper connecting arm 111 includes a top plate portion 111a and left and right side plate portions 111b connected to the top plate portion 111a, the left and right side plate portions 111b extend downward to be located below the top plate portion 111a, the arm fixing end 131 is located below the top plate portion 111a, and a through hole 1311 extending left and right is provided on the arm fixing end 131, and an axle pin 111c is connected between the left and right side plate portions 111b to pass through the through hole 1311. The arm elastic section 132 and the arm body 133 are located below the upper connecting arm 111, that is, within the air avoidance operation area 14. In this embodiment, the arm elastic section 132 includes a plurality of elastic sections 1321, which extend forward and backward. All elastic sections are arranged at intervals above and below, and adjacent elastic sections are sequentially connected end to end to form a whole. The top elastic section is connected to the arm fixed end 131, and the bottom elastic section is connected to the arm body 133. For example, the arm elastic section 132 includes five elastic sections. The front end of the top elastic section is connected to the front side of the arm fixed end 131, the rear end of the second elastic section from the top is connected to the rear end of the top elastic section to form a U-shape, the front end of the second elastic section from the top is connected to the front end of the third elastic section from the top to form a U-shape, the rear end of the third elastic section from the top is connected to the rear end of the fourth elastic section from the top to form a U-shape, the front end of the fourth elastic section from the top is connected to the front end of the fifth elastic section from the top to form a U-shape, and the rear end of the bottom elastic section is connected to the rear side of the arm body 133.

[0033] In the natural state, the locking protrusion 1331 protrudes forward and is in a locked state. When the unlocking pull-up portion 1332 is pulled up, the locking protrusion 1331 swings backward along with the arm body 133, and the locking protrusion 1331 moves backward to achieve an unlocked state. At this time, the arm elastic section 132 is in a deformed energy storage state. When the unlocking pull-up portion 1332 is released, the arm body 133 is reset under the action of the arm elastic section 132, so that the locking protrusion 1331 is reset forward and remains in a locked state.

[0034] There are at least two locking protrusions 1331, spaced apart vertically along the front side of the arm body 133. The hook portion 12 is provided with at least two buckle mounting locations (e.g., a first mounting location 121 and a second mounting location 122, where the first mounting location 122 is the outer periphery of the hook portion 12, and the second mounting location 122 is a buckle groove). Different locking protrusions 1331 are positioned at different front ends to lock different buckles (e.g., a first buckle 200 and a second buckle 300, where the first buckle 200 is mounted in the first mounting location 121 and the second buckle 300 is mounted in the second mounting location 122). The arm body 133 is gradually extended forward from top to bottom, so that: in a natural state, the front end of the locking protrusion 1331 located below exceeds the front end of the locking protrusion 1331 located above, the front end of the locking protrusion 1331 located below protrudes out of the front end surface of the hook portion 12, and the front end of the locking protrusion 1331 located above is located behind the front end surface of the hook portion 12. The locking protrusion 1331 located above can be used to lock a smaller buckle, so the buckle on the bag can be made smaller, and the bicycle connecting seat can also meet the fixing requirements of the bag. The connection between the unlocking pull portion 1332 and the arm body 133 (defined as the first connection) is located above the connection between the locking protrusion (1331) and the arm body (133) (defined as the second connection), that is, the first connection is higher than the second connection.

[0035] The arm fixing end 131 is provided with a slot 1312. The upper end of the slot 1312 extends through the bottom of the through hole 1311, breaking the peripheral sidewall of the through hole 1311 into a C-shape. The lower end of the slot 1312 extends through the lower end of the arm fixing end 131. The slot 1312 better accommodates assembly dimensional errors, making installation of the arm fixing end 131 easier. Furthermore, the arm fixing end 131 has an extension 1313 extending rearward, with an upper abutment protrusion 1314 protruding from the top of the rear end of the extension 1313.

[0036] The design focus of the utility model is that it is mainly through the connection of the elastic locking arm on the upper connecting arm of the first mounting part, the structure of the elastic locking arm is simple and ingenious, and it includes an arm fixing end, an arm elastic section and an arm body connected in sequence from top to bottom, and the front side of the arm body is provided with a locking protrusion protruding forward, and the rear side of the arm body is provided with an unlocking lever protruding backward. When in use, in a natural state, the locking protrusion protrudes forward to enter a locked state, and when the unlocking lever is pulled up, the locking protrusion is deflected backward along with the arm body, and the locking protrusion moves backward to achieve the unlocked state. At this time, the elastic section of the arm is in a deformed energy storage state, and the unlocking lever is released, and the arm body is reset under the action of the elastic section of the arm, so that the locking protrusion is reset forward and maintains the locked state; this elastic locking arm can play a stable locking role for the buckle installed on the bicycle connecting seat, and the unlocking operation is more convenient. Moreover, this elastic locking arm can be injection molded in one step, which is easy to produce and process, and at the same time makes the structure of the bicycle connecting seat more simplified.

[0037] The position of the locking protrusion of this elastic locking arm can be flexibly set, so it can meet the locking requirements of buckles of different sizes. In particular, it solves the locking requirements of small-sized buckles, and the buckle does not have to meet the size restriction of extending downward to the bottom of the first mounting part.

[0038] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
