Description

Technical Field

[0001] This utility model relates to the technical field of lifting bollards, and in particular to a lifting bollard. Background Technology

[0002] Rising bollards are security products, and to meet the current demands of the security market, they need to offer both robust security performance and stability during use. Currently, hydraulic bollards are prone to pressure leaks, causing the bollard to descend. Therefore, customers often choose bollards with electric screw drives to prevent this descent after pressure leaks.

[0003] However, the electric bollard mechanism uses a gear reduction structure. Under motor operation, the gear reduction mechanism drives the lead screw to raise and lower the bollard. Therefore, in the product design, appropriate clearances are required between the bollard and the top ring, and between the lead screw and the telescopic tube, to ensure the normal operation of the bollard. After the bollard is raised to its position, the gearbox, lead screw, and bollard are in close contact, and under normal circumstances, the bollard will not wobble significantly. However, under external force, some loosening may occur between the gearbox, lead screw, and bollard. Due to the design clearances, this can cause the bollard to wobble noticeably. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a sway-proof lifting bollard.

[0005] The present invention provides the following technical solution: a lifting ground column, comprising: a foundation box mechanism, and a column mechanism that is lifted and connected to the foundation box mechanism; The foundation box mechanism includes: The foundation box shell has an internal mounting cavity. A connecting component is provided inside the mounting cavity, and the column mechanism is slidably connected to the outer shell of the foundation box through the connecting component; Anti-scratch top rings, a plurality of such anti-scratch top rings are provided on the upper part of the mounting cavity; The column mechanism includes: The column housing is slidably connected to the foundation box housing via the connecting assembly; A drive assembly for driving the cylindrical housing to move; A gap baffle is provided on the outer wall of the column housing. When the column housing is raised, the gap baffle is located between the anti-scratch top ring and the column housing.

[0006] Furthermore, the driving component includes: A ground column mechanism, wherein the ground column mechanism is fixedly connected to the upper part of the inner side of the column housing; A telescopic tube, which is fixedly connected to the connecting assembly; A transmission screw is fixedly connected to the output shaft of the ground column mechanism, and the transmission screw is threadedly connected to the telescopic pipe.

[0007] Furthermore, the driving component also includes: The protective sleeve is fixedly connected to the ground column mechanism, the transmission screw is located inside the protective sleeve, and the protective sleeve is slidably connected to the telescopic tube.

[0008] Furthermore, the foundation box housing includes: The box body includes a bottom wall and side walls, and the top is open. The foundation box cover is provided on the top of the box body.

[0009] Furthermore, the connection component includes: Guide rods, a plurality of the guide rods being fixedly connected to the foundation box cover in a circumferential manner; The guide rod is connected to the middle frame plate at one end away from the foundation box cover; A support frame is provided on the side of the middle frame plate away from the foundation box cover, and a telescopic tube is fixedly connected to the support frame.

[0010] Furthermore, the connection component also includes: The buffer pads are a plurality of buffer pads that are fixedly connected in a ring around the side of the frame plate near the foundation box cover. When the column mechanism retracts, the bottom of the column mechanism contacts the buffer pads.

[0011] Furthermore, the support frame includes: Support rods, a number of support rods are fixedly connected in a ring on the side of the middle frame plate away from the foundation box cover; The lower frame plate is connected to the bottom end of the support rod, and the lower frame plate is fixedly connected to the telescopic tube.

[0012] Furthermore, the cylindrical outer shell includes: Columnar component; the columnar component is annular in shape; A column cover, wherein the column cover is disposed on the top of the column component; The lower outer wall of the column is provided with a number of long guide sleeves corresponding to the number of guide rods, and the long guide sleeves are slidably connected to the guide rods.

[0013] The beneficial effects of this utility model are: By installing a gap baffle at the bottom of the column component, the gap between the column component and the anti-scratch top ring can be reduced. When the column is raised, the swaying under the action of external force can be reduced. Moreover, since the added gap baffle is within the overlap range between the column component and the foundation box, it will not affect the appearance or operation of the product. By designing the ground column mechanism inside the column mechanism, the overlap range between the transmission screw and the column component is increased, which allows the column component to wobble, requiring a larger external force to achieve this. By designing a long guide sleeve, no resistance is generated during the lifting and lowering of the column component without reducing the operating clearance between the long guide sleeve and the guide rod. Under lateral forces, when the column sways left and right, the inner wall of the long guide sleeve exerts an opposite force on the guide rod, reducing the swaying of the column component.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] This embodiment provides a rising ground column, such as Figure 1 As shown, it includes: a foundation box mechanism 1, and a column mechanism 2 that is lifted and connected to the foundation box mechanism 1; Among them, the foundation box mechanism 1 is buried underground. In the initial state, the column mechanism 2 is located inside the foundation box mechanism 1. In the use state, the column mechanism 2 rises from the inside of the foundation box mechanism 1.

[0026] In this embodiment, the foundation box mechanism 1 includes: a foundation box shell, a connecting assembly, and several anti-scratch top rings; like Figure 2 As shown, the outer shell of the foundation box is cylindrical in shape and has an internal mounting cavity. Specifically, the outer shell of the foundation box includes a box body 11 and a foundation box cover 12. The box body 11 includes a bottom wall and side walls, and the top is open. The top of the box body 11 is detachably connected to the foundation box cover 12 by screws. A through hole is formed in the middle of the foundation box cover 12 so that the column mechanism 2 can pass through.

[0027] like Figure 3 and Figure 4 As shown, a connecting component is installed inside the mounting cavity of the foundation box shell, and the column mechanism 2 is slidably connected to the foundation box shell through the connecting component; The connecting components include: guide rod 14, middle frame plate 17, support frame and upper frame plate 15; Several guide rods 14 are fixedly connected to the foundation box cover 12 in a ring-like manner; Specifically, the three guide rods 14 are fixedly connected to the bottom of the foundation box cover 12 in a circular and evenly spaced manner. In other embodiments, the number of guide rods 14 can be adjusted according to the actual situation.

[0028] The end of the guide rod 14 away from the foundation box cover 12 is connected to the middle frame plate 17; Specifically, the top of the middle frame plate 17 is fixedly connected to the bottom of the three guide rods 14; a through hole is formed in the middle of the middle frame plate 17 so that the telescopic tube 24 can pass through for installation.

[0029] A support frame is provided on the side of the middle frame plate 17 away from the foundation box cover 12, and a telescopic pipe 24 is fixedly connected to the support frame; It is worth noting that the support frame includes: support rods 19 and lower frame plate 110; several support rods 19 are fixedly connected in a ring on the side of the middle frame plate 17 away from the foundation box cover 12; the bottom end of the support rods 19 is connected to the lower frame plate 110, and the lower frame plate 110 is fixedly connected to the telescopic tube 24. Specifically, the bottom side of the middle frame plate 17 is fixedly connected with three support rods 19 in a ring-like manner; the three support rods 19 are evenly spaced; the top of the lower frame plate 110 is fixedly connected to the bottom of the three support rods 19, and the middle part of the lower frame plate 110 is fixedly connected to the bottom of the telescopic tube 24.

[0030] The upper frame plate 15 is fixedly connected to the inner wall of the box 11 and is located at the upper part of the inner side of the box 11. All three guide rods 14 pass through the upper frame plate 15. A through hole is opened in the middle of the upper frame plate 15 so that the column mechanism 2 can pass through. When the column mechanism 2 is raised to the position, the lower part of the column mechanism 2 contacts the upper frame plate 15. The upper frame plate 15 is used to restrict the column mechanism 2 from moving further upward.

[0031] Furthermore, the connecting assembly also includes: buffer pads 18, a number of buffer pads 18 are fixedly connected in a ring around the side of the middle frame plate 17 near the foundation box cover 12, and when the column mechanism 2 retracts, the bottom of the column mechanism 2 contacts the buffer pads 18. Specifically, the top of the middle frame plate 17 is fixedly connected with three buffer pads 18. When the column mechanism 2 retracts, the bottom of the column mechanism 2 contacts the buffer pads 18 to achieve buffering of the column mechanism 2.

[0032] like Figure 3 and Figure 4 As shown, several anti-scratch top rings are provided on the upper part of the mounting cavity of the foundation box shell; Specifically, two anti-scratch top rings are provided on the upper part of the mounting cavity of the foundation box shell. The two anti-scratch top rings are the upper anti-scratch top ring 13 and the lower anti-scratch top ring 16. The upper anti-scratch top ring 13 is located on the upper side of the lower anti-scratch top ring 16. The anti-scratch top rings are used to prevent the column component 21 from contacting the foundation box cover 12, thereby causing the surface of the column component 21 to be scratched. Furthermore, since there are still quite a few column parts 21 inside the box 11 when the column part 21 is raised, and the size of one anti-scratch top ring does not extend all the way to the upper frame plate 15, another anti-scratch top ring is installed on the upper frame plate 15.

[0033] Understandably, the upper anti-scratch top ring 13 is fixedly connected to the foundation box cover 12 by screws, and the lower anti-scratch top ring 16 is fixedly connected to the upper frame plate 15 by screws. The diameter of the through hole formed in the middle of the upper anti-scratch top ring 13 and the lower anti-scratch top ring 16 is smaller than the diameter of the through hole in the middle of the foundation box cover 12 and the upper frame plate 15, thereby preventing the column part 21 from contacting the foundation box cover 12 and the upper frame plate 15 and causing scratches.

[0034] like Figures 5-7 As shown, the column mechanism 2 includes: a column housing, a drive assembly, and a gap baffle 26; the column housing is slidably connected to the foundation box housing via a connecting assembly; the drive assembly is used to drive the column housing to move; the gap baffle 26 is provided on the outer wall of the column housing, and when the column housing is raised, the gap baffle 26 is located between the anti-scratch top ring and the column housing.

[0035] The outer shell of the column includes: a column component 21, a column cover 22, and a long guide sleeve 23. The column component 21 is in the shape of a ring. The column cover 22 is provided on the top of the column component 21. The lower outer wall of the column component 21 is provided with a number of long guide sleeves 23 corresponding to the number of guide rods 14. The long guide sleeves 23 are slidably connected to the guide rods 14.

[0036] Specifically, the column component 21 is annular, and the base mechanism 27 is installed inside the column component 21. The top of the column component 21 is fixedly connected to the column cover 22 by screws to seal the top of the column component 21. Three long guide sleeves 23 are fixedly connected in a ring-like manner on the lower outer wall of the column component 21. The three long guide sleeves 23 are slidably connected to three guide rods 14 respectively. The length of the long guide sleeves 23 is 43.5mm±0.5mm, which is 14.5mm longer than the normal guide sleeve 29mm, so that the contact area between the long guide sleeves 23 and the guide rods 14 is wider. A ring-shaped gap baffle 26 is fixedly connected to the lower part of the outer wall of the column component 21. When the column shell is raised, the gap baffle 26 is located between the anti-scratch top ring and the column component 21, thereby reducing the gap between the column component 21 and the anti-scratch top ring. When the column component 21 is raised, the gap can be reduced by shaking under the action of external force. Furthermore, since the added gap baffle 26 is located within the overlap area between the column part 21 and the box body 11, it will not affect the appearance or operation of the product.

[0037] The drive assembly includes: a ground column mechanism 27, a telescopic tube 24, and a transmission screw 210. The ground column mechanism 27 is fixedly connected to the upper part of the inner side of the column housing; the telescopic tube 24 is fixedly connected to the connecting assembly; the transmission screw 210 is fixedly connected to the output shaft of the ground column mechanism 27, and the transmission screw 210 is threadedly connected to the telescopic tube 24. Specifically, the ground column mechanism 27 consists of a motor and a gearbox. The power of the motor is transmitted to the transmission screw 210 after passing through the gearbox. Since the specific structure of the ground column mechanism 27 is existing technology, it will not be described in detail here. A lower support plate 28 and an upper support plate 29 are fixedly connected to the inner side of the column housing. The ground column mechanism 27 is fixedly installed between the lower support plate 28 and the upper support plate 29. The bottom of the telescopic tube 24 is fixedly connected to the lower frame plate 110. The telescopic tube 24 includes a tube body and a threaded sleeve fixedly connected to the top of the tube body. The threaded sleeve is screwed to the transmission screw 210. The screw 210 can move through the threaded sleeve to the inside of the tube. When the column mechanism 2 retracts into the base box mechanism 1, the transmission screw 210 also moves completely to the inside of the tube. The tube can protect the transmission screw 210 to prevent surface contamination and instability of the column mechanism 2. The top of the transmission screw 210 is fixedly connected to the output shaft of the base column mechanism 27. The power output by the base column mechanism 27 drives the transmission screw 210 to rotate. The rotation of the transmission screw 210, through its engagement with the threaded sleeve, drives the column mechanism 2 to rise and fall on the base box mechanism 1.

[0038] Furthermore, the drive assembly also includes: a sheath 25, a sheath 25 fixedly connected to the ground column mechanism 27, a transmission screw 210 located inside the sheath 25, and the sheath 25 being slidably connected to the telescopic tube 24; It is understandable that when the column mechanism 2 is lifted, the transmission screw 210 moves out from the inside of the tube. In order to protect the transmission screw 210 and avoid surface contamination, a protective sleeve 25 is provided. After the transmission screw 210 moves out from the inside of the tube, the protective sleeve 25 can prevent impurities from adhering to the transmission screw 210 and causing inconvenience in movement.

[0039] In summary, by designing the ground column mechanism 27 inside the column mechanism 2 and increasing the overlap between the transmission screw 210 and the column component 21, the column component 21 can be made to sway, which requires a larger external force to achieve.

[0040] By designing a long guide sleeve 23, the operating gap between the long guide sleeve 23 and the guide rod 14 is not reduced, ensuring that no resistance is generated during the lifting and lowering of the column component 21. Under lateral force, when the column sways left and right, the inner wall of the long guide sleeve 23 will exert an opposite force on the guide rod, reducing the swaying of the column component 21.

[0041] By providing a gap baffle 26 at the lower part of the column component 21, the gap between the column component 21 and the anti-scratch top ring can be reduced. When the column is raised, the swaying under the action of external force can be reduced. Moreover, since the increased gap baffle 26 is within the overlap range between the column component 21 and the foundation box, it will not affect the appearance or operation of the product.
