Description

Technical Field

[0001] The utility model relates to the technical field of parking racks, in particular to a double-column parking rack. Background Art

[0002] When a bicycle is not being ridden, it needs to be parked using a parking rack. There are two types of existing bicycle parking racks: one is a single-column parking rack and the other is a double-column parking rack. Both have their own advantages and disadvantages. For example, the single-column parking rack is less stable when parked and is prone to running or tipping over. However, the single-column parking rack is less likely to hinder the movement of the bicycle when folded; while the double-column parking rack is more stable when parked and is less likely to run or tip over. However, the commonly used double-column parking rack is not easy to fold, and the commonly used integrated double-column parking rack still occupies a large width after folding, which often affects the movement of the bicycle and creates an obstruction or danger.

[0003] Among existing patents, Chinese patent document No. 200820206667.7 discloses a double-post parking stand comprising a fixed frame head and a double-post leg. The fixed frame head is provided with a pivoting slot and a clamping slot, the pivoting slot being connected and adjacent to the clamping slot. The width between the left and right opposing sides of the clamping slot is smaller than the width between the left and right opposing sides of the pivoting slot. The double-post leg comprises two independent legs and a rotating shaft. Each independent leg has a pivoting end that can be symmetrically received and movably pivoted together in the pivoting slot of the fixed frame head. A linkage structure is provided between the two independent legs to enable synchronous pivoting. The rotating shaft pivots the two independent legs through the pivoting slot of the fixed frame head. The linkage structure comprises an insert and a slot, the insert and the slot being respectively located on opposing walls of the two independent legs. Guide arc surfaces are formed at the intersections of opposing side walls of the pivoting slot of the fixed frame head and opposing side walls of the clamping slot. The width between the left and right opposite sides of the clip receiving groove in this patent document is smaller than the width between the left and right opposite sides of the pivot receiving groove. The intersections of the opposite side walls of the pivot receiving groove of the fixed frame head and the opposite side walls of the clip receiving groove are each formed with a guide arc surface. The insert block and the slot are directly machined and formed on the two foot posts. The structure is complex and the processing is difficult. In addition, the integrity of the foot posts is lacking, which easily leads to a decrease in the strength of the foot posts.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the present utility model is to provide a double-column parking stand.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The top of the two legs is connected to the two sleeves, and the top of the two legs is connected to the sleeves, and the sleeves are connected to the two sleeves respectively.

[0008] Furthermore, an arc-shaped abutment portion is provided at the top of the foot column; when the foot column is in an upright supporting state, the pressing block abuts against the arc-shaped abutment portion; when the foot column is in a folded state, the pressing block abuts against the rear side surface of the foot column.

[0009] Furthermore, a downwardly inclined surface is provided on the front side of the arc-shaped abutting portion.

[0010] Furthermore, a fixing hole is concavely provided on the top surface of the pressing block, and the bottom end of the elastic member is inserted into the fixing hole.

[0011] Furthermore, the fixing frame head is provided with a lock hole.

[0012] Furthermore, the bottom end of the foot column is covered with an anti-slip sleeve.

[0013] Furthermore, the elastic member is a spring.

[0014] The beneficial effects of the present invention are as follows: in actual application, the fixed frame head is installed on the bicycle frame. When the two sleeves are in the upright supporting state, the elastic force of the elastic member applies an elastic force to the pressure block, so that the pressure block presses the top of the foot column, thereby stably maintaining the upright supporting state; when the foot column needs to be folded, an upward swinging force is applied to the foot column, so that the foot column overcomes the elastic force of the elastic member and swings upward, so that the top of the foot column first presses the pressure block upward, and when the foot column swings upward until it contacts the top edge of the rotating notch, the foot column is in the folded state. At this time, the elastic force of the elastic member drives the pressure block to press the rear side of the foot column, so that the foot column is stably in the folded state. In the process of the foot column swinging upward to fold or swinging downward to stand up and support, the two foot columns swing synchronously under the cooperation of the drive rod and the waist-shaped linkage hole. Because the two sleeves are symmetrically arranged, the forward projections of the two sleeves on the vertical plane are in an inverted V shape, the cross-sections of the two sleeves on the horizontal plane are arranged at an angle, the distance between the two sleeves gradually decreases from front to back, and the axis of the rotating shaft is perpendicular to the central axis of the sleeve. Therefore, when the two foot posts are in the folded state, the distance between the two foot posts will become narrower, reducing the risk of the rider's feet scratching or colliding with the foot posts. When the two foot posts are in the upright support state, the distance between the two foot posts will become wider, which is conducive to providing stable support. The structure of the utility model is simple. By optimizing the structure of the two sleeves, the stability of the two foot posts when folded or upright is good. When switching between the folded state and the upright support state, the distance between the two foot posts will undergo adaptive changes and adjustments, which is highly practical.

[0022] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0023] like Figures 1 to 5 As shown, the utility model provides a double-column parking frame, which includes a fixed frame head 1, two foot columns 2 and two spring-pressing components 3. Two sleeves 4 are symmetrically arranged at the bottom of the fixed frame head 1. The forward projection of the two sleeves 4 on the vertical plane is an inverted V shape. The cross-section of the two sleeves 4 on the horizontal plane is set at an angle or an eight-shaped setting. The distance between the two sleeves 4 gradually decreases from front to back. The two spring-pressing components 3 are respectively arranged in the two sleeves 4. The top ends of the two foot columns 2 are respectively extended into the two sleeves 4. The top ends of the foot columns 2 are rotatably connected to the sleeves 4 via a rotating shaft 16. The rotating shaft 16 and the sleeves The tube 4 is arranged vertically, and a rotation notch 5 is provided on the rear side of the bottom port of the two sleeves 4. The rotation notch 5 is used for the foot column 2 to swing upward. The spring-pressing assembly 3 includes a pressure block 6 and an elastic member 7. The top of the elastic member 7 conflicts with the top plate of the sleeve 4 or the fixed frame head 1, and the bottom end of the elastic member 7 conflicts with the pressure block 6. The pressure block 6 conflicts with the top of the foot column 2. One foot column 2 is provided with a linkage plate 8, and the linkage plate 8 is provided with a waist-shaped linkage hole 9. The other foot column 2 is provided with a driving rod 10, which is tilted downward and passes through the waist-shaped linkage hole 9. The driving rod 10 conflicts with the inner wall of the waist-shaped linkage hole 9.

[0024] In actual application, the fixed frame head 1 is installed on the bicycle frame. When the two sleeves 4 are in the upright supporting state, the elastic force of the elastic member 7 applies an elastic force to the pressure block 6, so that the pressure block 6 presses the top of the foot column 2, so that the foot column 2 is stably in the upright supporting state. When the foot column 2 needs to be folded, an upward swinging force is applied to the foot column 2, so that the foot column 2 overcomes the elastic force of the elastic member 7 and swings upward, so that the top of the foot column 2 first presses the pressure block 6 upward. When the foot column 2 swings upward until it contacts the top edge of the rotating notch 5, the foot column 2 is in the folded state. At this time, the elastic force of the elastic member 7 drives the pressure block 6 to press the rear side of the foot column 2, so that the foot column 2 is stably in the folded state. In the process of the foot column 2 swinging upward to fold or swinging downward to stand up and support, the two foot columns 2 swing synchronously under the cooperation of the drive rod 10 and the waist-shaped linkage hole 9. Because the two sleeves 4 are symmetrically arranged, the forward projections of the two sleeves 4 on the vertical plane are in an inverted V shape, the cross-sections of the two sleeves 4 on the horizontal plane are arranged at an angle, the distance between the two sleeves 4 gradually decreases from front to back, and the axis of the rotating shaft 16 is perpendicular to the central axis of the sleeve 4. Therefore, when the two foot posts 2 are in the folded state, the distance between the two foot posts 2 will become narrower, reducing the risk of the rider's feet rubbing against or colliding with the foot posts 2. When the two foot posts 2 are in the upright support state, the distance between the two foot posts 2 will become wider, which is conducive to providing stable support. The structure of the utility model is simple. By optimizing the structure of the two sleeves 4, the stability of the two foot posts 2 when folded or upright is good. When switching between the folded state and the upright support state, the distance between the two foot posts 2 will undergo adaptive changes and adjustments, which is highly practical.

[0025] Specifically, the linkage plate 8 and the driving rod 10 are respectively welded to the relative positions of the two foot columns 2. Compared with directly processing and forming the waist-shaped linkage hole 9 and the driving rod 10 on the two foot columns 2, the processing and forming of this application is easier and will not affect the strength and integrity of the foot columns 2 themselves.

[0026] In this embodiment, the top of the leg 2 is provided with an arcuate abutment portion 11. When the leg 2 is in the upright supporting position, the pressure block 6 abuts against the arcuate abutment portion 11. When the leg 2 is in the folded position, the pressure block 6 abuts against the rear side of the leg 2. When the leg 2 swings, the arcuate abutment portion 11 and the pressure block 6 slide against each other, reducing friction and wear, making the swing of the leg 2 more stable and smooth.

[0027] In this embodiment, a downwardly inclined surface 12 is provided on the front side of the arc-shaped abutting portion 11. This structural design is conducive to the rotation and swing of the leg 2 and facilitates the pressing block 6 to stably maintain the leg 2 in the folded state.

[0028] In this embodiment, the top surface of the pressing block 6 is concavely provided with a fixing hole 13, and the bottom end of the elastic member 7 is inserted into the fixing hole 13. This structural design facilitates the assembly and disassembly of the elastic member 7 and improves the position accuracy and working stability of the elastic member 7.

[0029] In this embodiment, the fixing frame head 1 is provided with a locking hole 14 , and a bolt passes through the locking hole 14 and is threadedly connected to the bicycle frame, so as to facilitate installation of the fixing frame head 1 on the bicycle frame.

[0030] In this embodiment, the bottom end of the foot column 2 is covered with an anti-slip cover 15, which is a rubber cover and plays the role of anti-slip support and is not easy to wear.

[0031] In this embodiment, the elastic member 7 is a spring.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
