Description

Technical Field

[0001] This utility model relates to the field of bicycle bracket technology, and more specifically, to a bicycle bracket. Background Technology

[0002] Currently, some wall-mounted bicycle racks on the market have achieved convenient storage and retrieval of bicycles through innovative designs. This is especially beneficial for users with less strength, such as women, children, or some adult men. Simply pushing the front wheel of the bicycle into the designated mechanism allows for easy vertical lifting and lowering of the bicycle, securing it to the wall and solving the space-consuming problem of traditional storage methods. This design greatly improves the convenience of bicycle storage and retrieval, enabling even users with less strength to independently complete the operation.

[0003] However, while these supports offer convenience, they also expose certain safety hazards. For example, Chinese patent application number 201780076026.6 discloses a bicycle parking device including a bracket, a slide mounted on the bracket, the slide being movable on a guide rail of the bracket and connected to a lifting unit (spring), and a wheel fixing mechanism mounted on the slide. The slide can be locked in a low position by the slide fixing unit mounted on the bracket. If it is necessary to park the bicycle vertically, the wheel is pushed into the wheel fixing mechanism, and the wheel presses against the pedal. This is equivalent to triggering the unlocking device, and the slide and the slide fixing unit are released. The loosened slide and wheel fixing mechanism, together with the fixed wheel, are lifted upward with the help of the guide rail and the spring.

[0004] While the above design excels in convenience, it poses certain safety hazards. Specifically, if a user or child accidentally presses the pedal, triggering the unlocking device, the slide and its fixing unit will be released. At this point, the slide will move rapidly upward under the action of the spring, causing the wheel fixing mechanism and other components mounted on it to move upward at high speed, which could cause injury to people in the vicinity. Utility Model Content

[0005] The main purpose of this utility model is to provide a bicycle bracket that can solve the problem that, due to accidental contact during use, the component used to hold the wheels may suddenly move upwards, causing injury to people in the vicinity.

[0006] To achieve the above objectives, this utility model provides a bicycle bracket, including a column and a base. The base is movably mounted on the column in a vertical direction. The base is equipped with a triggering device and a wheel placement assembly for receiving wheels. When the triggering device is activated, the base moves upward in a vertical direction relative to the column. The bicycle bracket also includes a safety structure, comprising: a first limiting structure, including a first limiting member, which is movably mounted relative to the column in a first direction to allow the first limiting member to switch between a first position and a second position; and a second limiting structure, which cooperates with the first limiting structure. One of the first and second limiting structures is mounted on the column, and the other is mounted on the base. When the first limiting member is in the first position, the first limiting member and the second limiting structure form a stop in the vertical direction; when the first limiting member is in the second position, the first limiting member and the second limiting structure are released from the stop.

[0007] Furthermore, the first limiting member includes an anti-detachment structure. When the first limiting member is in the first position, the anti-detachment structure can cooperate with the first limiting structure so that the first limiting member and the second limiting structure can form a stop limit in the vertical direction and an anti-detachment limit in the first direction.

[0008] Furthermore, the first limiting structure also includes a mounting base with a receiving cavity communicating with the outside. The first limiting member is movably disposed in the receiving cavity along a first direction. The operating end of the first limiting member can cooperate with one end of the mounting base to keep the first limiting member in a first position or a second position.

[0009] Furthermore, the first limiting structure also includes an elastic element, which is located in the receiving cavity and sleeved on the first limiting element. The elastic element can provide the first limiting element with a force to move in the direction of the first limiting element toward the second limiting structure.

[0010] Furthermore, the first limiting member can rotate relative to the receiving cavity. The first limiting structure also includes a second limiting member, which is connected to the first limiting member. A first groove and a second groove are provided on the end face of the mounting base away from the column. The depth of the first groove is greater than the depth of the second groove. When the first limiting member is in the first position, the end of the second limiting member is engaged in the first groove. When the first limiting member is in the second position, the end of the second limiting member is engaged in the second groove.

[0011] Furthermore, there are two first grooves and two second grooves. When the first limiting member is in the first position, the two ends of the second limiting member are respectively inserted into the two first grooves. When the first limiting member is in the second position, the two ends of the second limiting member are respectively inserted into the two second grooves.

[0012] Furthermore, the anti-detachment structure includes an annular groove, and the second limiting structure includes a baffle. When the first limiting member is in the first position, if the base moves upward in the vertical direction relative to the column, the baffle is inserted into the annular groove and can form a stop limiting with the annular groove in the vertical direction and an anti-detachment limiting with the annular groove in the first direction. At this time, the first limiting member cannot release the limiting from the second limiting structure.

[0013] Furthermore, the anti-detachment structure also includes a coaxial first cylindrical segment and a second cylindrical segment. The diameter of the first cylindrical segment is larger than the diameter of the second cylindrical segment. One end of the second cylindrical segment is connected to the first cylindrical segment, and the other end of the second cylindrical segment is provided with an annular protrusion. An annular groove is formed between the annular protrusion and the first cylindrical segment.

[0014] Furthermore, the second limiting structure is disposed on the base, and the baffle includes a first plate segment and a second plate segment. One end of the first plate segment is fixedly connected to the base, and the other end of the first plate segment is bent upward and extended. One end of the second plate segment is connected to the first plate segment, and the side of the second plate segment facing the base is fixedly connected to the base.

[0015] Furthermore, the safety structure also includes an operating part, which is installed at the end of the first limiting member away from the second limiting structure, and the operating part is located on the side of the second limiting member away from the second limiting structure.

[0016] The present invention employs a safety structure, which includes a first limiting structure and a second limiting structure. The first limiting structure includes a first limiting member. When the base is stopped at the bottom of the column, the first limiting member is in a first position. At this time, the first limiting member and the second limiting structure can form a stop and limit in the vertical direction. Even if the triggering device is accidentally switched to the triggering state, the base cannot move upward quickly relative to the column, forming an anti-accidental collision mechanism to avoid injury to personnel.

[0041] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] See also Figures 1 to 21 As shown, this utility model provides a bicycle bracket, which includes a column 20 and a base 40. The base 40 is movably mounted on the column 20 in a vertical direction. The base 40 is provided with a triggering device and a wheel placement assembly for receiving wheels. When the triggering device is triggered, the base 40 moves upward in a vertical direction relative to the column 20. The bicycle bracket also includes a safety structure, which includes a first limiting structure 10, including a first limiting member 11. The first limiting member 11 is movably mounted relative to the column 20 in a first direction to allow the first... The limiting member 11 switches between a first position and a second position; the second limiting structure 30 is used to cooperate with the first limiting structure 10, one of the first limiting structure 10 and the second limiting structure 30 is installed on the column 20, and the other of the first limiting structure 10 and the second limiting structure 30 is installed on the base 40; when the first limiting member 11 is in the first position, the first limiting member 11 and the second limiting structure 30 form a stop and limit in the vertical direction, and when the first limiting member 11 is in the second position, the first limiting member 11 and the second limiting structure 30 are released from the limit.

[0043] In this embodiment, the wheel placement assembly is used to place and hold the front or rear wheel of a bicycle. The triggering device has a triggered state and a non-triggered state. When the triggering device is triggered and in the triggered state, the base 40 drives the wheel placement assembly to move vertically upward relative to the column 20 to hang the bicycle. When the triggering device is triggered and in the non-triggered state, the base 40 stops at the bottom of the column 20, and the wheel placement assembly is also located at the bottom of the column 20. At this time, the bicycle can be removed from the bicycle bracket or the front or rear wheel of the bicycle can be pushed into the wheel placement assembly. The first direction refers to... Figure 11 The first limiting member 11 has a first position and a second position, and is movable relative to the column 20 in a first direction to switch between the first position and the second position. One of the first limiting structure 10 and the second limiting structure 30 is mounted on the column 20, and the other of the first limiting structure 10 and the second limiting structure 30 is mounted on the base 40 and is movable with the base 40 relative to the column 20 in a vertical direction.

[0044] In the initial state, the base 40 is located at the bottom of the column 20, and the triggering device is in a non-triggered state, allowing the base 40 to remain stationary at the bottom of the column 20. Because the base 40 is located at a low position, if someone accidentally touches the triggering device, it will cause the triggering device to switch from a non-triggered state to a triggered state. At this time, the base 40 will move vertically upward relative to the column 20, which may injure the person's hand or other contact parts, posing a safety hazard. Therefore, a safety structure is set on the bicycle bracket to solve the problem that the component used to hold the wheels may suddenly move upward due to accidental contact during the use of the existing bicycle parking device, causing injury to people around.

[0045] Specifically, when the base 40 is stopped at the bottom of the column 20, the first limiting member 11 is in the first position. At this time, the first limiting member 11 and the second limiting structure 30 can form a stop limit in the vertical direction. Even if the triggering device is accidentally triggered and switched to the triggering state, the base 40 cannot move upward relative to the column 20, forming an anti-accidental collision mechanism to avoid injury to personnel. When it is necessary to hang the bicycle, the first limiting member 11 can be in the second position. At this time, the first limiting member 11 and the second limiting structure 30 release the vertical limit. When the triggering device is triggered, the base 40 can move upward in the vertical direction relative to the column 20 to hang the bicycle.

[0046] It should be noted that the triggering device and the wheel placement assembly are not the core improvements of this application. The triggering device can be the pedal in 201780076026.6, and the wheel placement assembly can be the wheel fixing mechanism in 201780076026.6. At the same time, the triggering device and the wheel placement assembly are not limited to the corresponding structures in 201780076026.6, but can also be other existing technologies that can achieve the same function.

[0047] See also Figures 1 to 21 As shown, in one embodiment of the present invention, the first limiting member 11 includes an anti-detachment structure. When the first limiting member 11 is in the first position, the anti-detachment structure can cooperate with the first limiting structure 10 so that the first limiting member 11 and the second limiting structure 30 can form a stop limit in the vertical direction and an anti-detachment limit in the first direction.

[0048] In this embodiment, when the first limiting member 11 is in the first position, if the triggering device is accidentally touched, that is, the triggering device has been switched to the triggering state, without an anti-detachment structure, the user may directly switch the first limiting member 11 to the second position without the user's knowledge, and the base 40 will still suddenly slide upward. The first limiting member 11 includes an anti-detachment structure, so that even if a person pulls the first limiting member 11, it cannot be moved along the first direction when the triggering device has been accidentally touched, that is, the first limiting member 11 cannot be switched to the second position, thus forming a secondary anti-accidental contact mechanism, further improving the safety of the bicycle bracket.

[0049] See also Figures 1 to 21 As shown, in one embodiment of the present invention, the first limiting structure 10 further includes a mounting base 12, the mounting base 12 having a receiving cavity 121 communicating with the outside, the first limiting member 11 being movably disposed in the receiving cavity 121 along a first direction, and the operating end of the first limiting member 11 being able to cooperate with one end of the mounting base 12 so that the first limiting member 11 is held in a first position or a second position.

[0050] In this embodiment, the operating end of the first limiting member 11 refers to the part used for manual operation, so that the user can easily control the movement of the first limiting member 11 in the first direction. The mounting base 12 has a receiving cavity 121 communicating with the outside for accommodating the first limiting member 11. The operating end of the first limiting member 11 can cooperate with one end of the mounting base 12 to keep the first limiting member 11 in a first position or a second position, allowing the user to adjust the first limiting member 11 to the first position or the second position as needed, and once adjusted to the correct position, the first limiting member 11 can be stably maintained in this position.

[0051] See also Figures 1 to 21As shown, in one embodiment of the present invention, the first limiting structure 10 further includes an elastic element 14, which is located in the receiving cavity 121 and sleeved on the first limiting element 11. The elastic element 14 can provide the first limiting element 11 with a force that moves it in the direction of the first direction toward the second limiting structure 30.

[0052] In this embodiment, when the first limiting member 11 is in the second position, the elastic member 14 is compressed. When the operator operates the operating end of the first limiting member 11 to switch the first limiting member 11 from the second position to the first position, under the elastic restoring force of the elastic member 14, the first limiting member 11 can move along the first direction toward the direction close to the second limiting structure 30, making the operation easier and reducing the user's physical exertion.

[0053] In one embodiment, the elastic element 14 is a spring.

[0054] See also Figures 1 to 21 As shown, in one embodiment of the present invention, the first limiting member 11 is rotatable relative to the receiving cavity 121. The first limiting structure 10 also includes a second limiting member 13, which is connected to the first limiting member 11. A first groove 122 and a second groove 123 are provided on the end face of the mounting base 12 away from the column 20. The depth of the first groove 122 is greater than the depth of the second groove 123. When the first limiting member 11 is in the first position, the end of the second limiting member 13 is inserted into the first groove 122. When the first limiting member 11 is in the second position, the end of the second limiting member 13 is inserted into the second groove 123.

[0055] In this embodiment, by setting a first groove 122 and a second groove 123 of different depths, the end of the second limiting member 13 is engaged in the grooves of different depths, so that the first limiting member 11 can be maintained in the first position or the second position. For ease of understanding, the switching process is described in detail below. If the first limiting member 11 is currently in the first position and it is necessary to switch the first limiting member 11 to the second position, the operator pulls the operating end of the first limiting member 11, so that the first limiting member 11 moves away from the second limiting structure 30 in the first direction relative to the mounting base 12. When the first limiting member 11 moves away from the mounting base 12, the first limiting member 11 is rotated until the end of the second limiting member 13 is aligned with the second groove 123. Then, the first limiting member 11 is moved towards the second limiting structure 30 in the first direction until the end of the second limiting member 13 is engaged in the second groove 123, so that the first limiting member 11 is maintained in the second position.

[0056] If the first limiting member 11 is currently in the second position, and it is necessary to switch the first limiting member 11 to the first position, the operator pulls the operating end of the first limiting member 11 to move the first limiting member 11 away from the second limiting structure 30 in the first direction relative to the mounting base 12 until the first limiting member 11 is outside the mounting base 12. Then, the operator rotates the first limiting member 11 until the end of the second limiting member 13 is aligned with the first groove 122. Then, the operator moves the first limiting member 11 towards the second limiting structure 30 in the first direction until the end of the second limiting member 13 is engaged in the first groove 122, thereby keeping the first limiting member 11 in the first position.

[0057] See also Figures 1 to 21 As shown, in one embodiment of the present invention, there are two first grooves 122 and two second grooves 123. When the first limiting member 11 is in the first position, the two ends of the second limiting member 13 are respectively inserted into the two first grooves 122. When the first limiting member 11 is in the second position, the two ends of the second limiting member 13 are respectively inserted into the two second grooves 123.

[0058] In this embodiment, when the first limiting member 11 is in the first position, both ends of the second limiting member 13 are respectively engaged in the two first grooves 122. When the first limiting member 11 is in the second position, both ends of the second limiting member 13 are respectively engaged in the two second grooves 123. Compared with single-end engagement, this double-end engagement ensures that even if one end of the second limiting member 13 fails due to wear, obstruction by foreign objects or other reasons, the other end can still be engaged in the groove, thus ensuring the stability of the first limiting member 11.

[0059] In one embodiment, the second limiting member 13 is provided with a thread in the middle, the first limiting member 11 is provided with a first threaded hole 115, the second limiting member 13 passes through the first threaded hole 115, and the middle part of the second limiting member 13 is threadedly engaged with the first threaded hole 115 to realize the connection between the first limiting member 11 and the second limiting member 13.

[0060] See also Figures 1 to 21 As shown, in one embodiment of the present invention, the anti-detachment structure includes an annular groove 111, and the second limiting structure 30 includes a baffle 31. When the first limiting member 11 is in the first position, if the base 40 moves upward relative to the column 20 in the vertical direction, the baffle 31 is inserted into the annular groove 111 and can form a stop limiting with the annular groove 111 in the vertical direction and an anti-detachment limiting with the annular groove 111 in the first direction. At this time, the first limiting member 11 cannot release the limiting from the second limiting structure 30.

[0061] In this embodiment, when the first limiting member 11 is in the first position, if the base 40 moves upward relative to the column 20 in the vertical direction, the baffle 31 will be engaged in the annular groove 111 and abut against the bottom wall of the annular groove 111, so that the first limiting member 11 and the second limiting structure 30 form a stop and limit in the vertical direction, preventing the base 40 from jumping up and causing injury to personnel after the triggering device is triggered. Along the length direction of the first limiting member 11, the annular groove 111 has a first side wall and a second side wall that are arranged opposite to each other. The baffle 31 is engaged in the annular groove 111 and is located between the first side wall and the second side wall. The first side wall and the second side wall can stop and limit the baffle 31 in the first direction, preventing the baffle 31 from coming out of the annular groove 111. At this time, the first limiting member 11 cannot release the limit from the second limiting structure 30, that is, the baffle 31 cannot come out of the annular groove 111 in the first direction.

[0062] See also Figures 1 to 21 As shown, in one embodiment of the present invention, the anti-detachment structure further includes a coaxial first cylindrical segment 112 and a second cylindrical segment 113. The diameter of the first cylindrical segment 112 is larger than the diameter of the second cylindrical segment 113. One end of the second cylindrical segment 113 is connected to the first cylindrical segment 112, and the other end of the second cylindrical segment 113 is provided with an annular protrusion 114. An annular groove 111 is formed between the annular protrusion 114 and the first cylindrical segment 112.

[0063] With the above settings, an annular groove 111 can be formed. When the first limiting member 11 is in the first position, the baffle 31 is inserted into the annular groove 111 and abuts against the bottom wall of the annular groove 111, so that the first limiting member 11 and the second limiting structure 30 form a stop limit in the vertical direction and an anti-disengagement limit in the first direction, so as to prevent the base 40 from jumping up and causing injury to personnel after the triggering device is triggered, thereby enhancing the safety of the bicycle bracket.

[0064] In one embodiment, an annular groove 111 can be directly machined on the first cylindrical segment 112, eliminating the need for manufacturing and assembling additional components and directly reducing production costs. Furthermore, the directly machined annular groove 111 is integral with the first cylindrical segment 112, eliminating the possibility of loosening or damage to additional components and increasing the reliability of the anti-detachment structure.

[0065] See also Figures 1 to 21 As shown, in one embodiment of the present invention, the second limiting structure 30 is disposed on the base 40, and the baffle 31 includes a first plate segment 311 and a second plate segment 312. One end of the first plate segment 311 is fixedly connected to the base 40, and the other end of the first plate segment 311 is bent upward and extended. One end of the second plate segment 312 is connected to the first plate segment 311, and the side of the second plate segment 312 facing the base 40 is fixedly connected to the base 40.

[0066] In this embodiment, the first limiting structure 10 is fixedly installed on the column 20, and the second limiting structure 30 is fixedly installed on the base 40. One end of the first plate segment 311 is fixedly connected to the base 40, ensuring the overall structural rigidity and firmness of the baffle 31. The other end of the plate segment 311 bends upward and extends upward. When the first limiting member 11 is in the first position, this end is inserted into the annular groove 111, forming a stop and limiting in the vertical direction with the annular groove 111. The side of the second plate segment 312 facing the base 40 is fixedly connected to the base 40, which can increase the mechanical strength of the baffle 31 and prevent the baffle 31 from deforming or shifting during operation.

[0067] See also Figures 1 to 21 As shown, in one embodiment of the present invention, the safety structure further includes an operation part 50, which is installed at the end of the first limiting member 11 away from the second limiting structure 30, and the operation part 50 is located on the side of the second limiting member 13 away from the second limiting structure 30.

[0068] In this embodiment, the operating part 50 is installed at the end of the first limiting member 11 away from the second limiting structure 30, so that the operator does not need to contact or go around the second limiting structure 30 during operation, eliminating obstacles that may be encountered during operation and simplifying the operation steps. The operating part 50 is located on the side of the second limiting member 13 away from the second limiting structure 30, which can avoid interference between the operating part 50 and the second limiting member 13.

[0069] In one embodiment, the operating part 50 is a pull ring, which is attached to the end of the first limiting member 11 away from the second limiting structure 30. The pull ring is easy to grip by hand, especially in emergency situations. Users can quickly identify and grab the pull ring to pull the first limiting member 11, so that the first limiting member 11 switches between the first position and the second position, making the operation process more direct and faster.

[0070] See also Figures 1 to 18 As shown, in one embodiment of this utility model, the first limiting structure 10 is mounted on the column 20, and the second limiting structure 30 is mounted on the base 40. The column 20 is provided with a through hole 21 and two second threaded holes 22. The end of the mounting base 12 facing the column is fixedly connected to the column 20 by two bolts 60. The two bolts 60 are correspondingly arranged with the two second threaded holes 22, and the bolts 60 pass through the corresponding second threaded holes 22 and are threaded into the second threaded holes 22. The through hole 21 allows one end of the first limiting member 11 to pass through the column 20 and engage with the second limiting structure 30 mounted on the base.

[0071] See also Figures 1 to 21As shown, in one embodiment of this utility model, one end of the elastic member 14 abuts or connects to the end of the first cylindrical section 112 facing the operating part, and the other end of the elastic member 14 abuts or connects to the inner wall of the receiving cavity 121. When the first limiting member 11 is in the second position, the elastic member 14 is compressed. If it is necessary to switch the first limiting member 11 to the first position, the operator pulls the operating part 50 to move the first limiting member 11 relative to the mounting base 12 in the first direction away from the second limiting structure 30 until the first limiting member 11 is outside the mounting base 12. Then, the operator rotates the first limiting member 11 until the end of the second limiting member 13 is aligned with the first groove 122. Then, the operator releases the hand, and under the elastic restoring force of the elastic member 14, the first limiting member 11 moves in the first direction towards the second limiting structure 30 until the end of the second limiting member 13 is inserted into the first groove 122, thereby keeping the first limiting member 11 in the first position.

[0072] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: a safety structure is provided, and the installation structure includes a first limiting structure and a second limiting structure. The first limiting structure includes a first limiting member. When the base is stopped at the bottom of the column, the first limiting member is in a first position.
