[0001] The present application relates to the technical field of anti-collision columns, in particular to an active anti-collision column. BACKGROUND

[0002] Anti-collision columns are a general term for columnar roadblocks, which are usually made of rubber, PVC (Polyvinyl Chloride) or steel pipes, have good warning and anti-collision functions, and are mainly installed in places such as shopping malls, branch junctions, highways and communities.

[0003] In related technologies, the anti-collision column structure includes an anti-collision column base and an anti-collision column body, and the anti-collision column body is usually fixedly connected with the anti-collision column base. This design has poor anti-collision effect and is inconvenient for maintenance or replacement of the anti-collision column body by the staff. SUMMARY

[0004] In order to solve or improve the technical problems of poor anti-collision effect of the anti-collision column structure in related technologies and inconvenience for maintenance or replacement of the anti-collision column body by the staff, the purpose of the present application is to provide an active anti-collision column.

[0005] To achieve the above-mentioned purpose, the present application provides an active anti-collision column, which comprises: a box body, the box body comprising a mounting cavity, a first limiting hole being arranged on the cavity wall of the mounting cavity; a column body, the column body comprising a hollow cavity, the column body being provided with a second limiting hole in communication with the hollow cavity, at least a part of the column body being arranged in the mounting cavity, the second limiting hole being arranged correspondingly to the first limiting hole; a mounting frame, the mounting frame being arranged in the hollow cavity and connected with the cavity wall of the hollow cavity, the mounting frame being provided with a third limiting hole, the third limiting hole being arranged correspondingly to the second limiting hole; a bolt, the bolt being movably arranged in the mounting frame, the bolt having a first limit position and a second limit position, the bolt being arranged in the third limiting hole when being in the first limit position; the bolt being arranged in the third limiting hole, the second limiting hole and the first limiting hole when being in the second limit position, so as to lock the position of the column body; an adjusting assembly, the adjusting assembly being arranged in the mounting frame and the column body, the adjusting assembly abutting against the bolt, the adjusting assembly being used for driving the bolt to move between the first limit position and the second limit position.

[0006] The present application aims to provide an active anti-collision column, which has the following advantages:

[0007] In the first aspect, the detachable connection between the column body and the box body can be achieved by adjusting the assembly and the cooperation of the latch. The column body can be in a locked state or an unlocked state by driving the latch to move relative to the mounting frame between the second limit position and the first limit position. When the latch is in the first limit position, the latch is only arranged in the third limiting hole, and at this time, the column body is not in the locked state, and the staff can install or disassemble the column body. When the latch is in the second limit position, the latch is arranged in the third limiting hole, the second limiting hole and the first limiting hole at the same time, and at this time, the column body is in the locked state (the column body is fixed relative to the box body). This design facilitates the staff to maintain or replace the crash barrier body, and is helpful to reduce the use and management cost.

[0008] In the second aspect, the crash barrier body can be matched with box bodies in different positions, which is helpful to flexibly adjust the position of the crash barrier body, and the crash barrier body has higher universality and wider application range.

[0009] In the third aspect, at least a part of the column body is arranged in the mounting cavity, and the outer wall of the column body abuts against the cavity wall of the mounting cavity. This design does not need the column body to be directly embedded in the ground or the concrete base, but the box body is connected with the ground or the concrete base, which is helpful to increase the contact area with the ground or the concrete base and improve the anti-collision effect.

[0010] In some technical solutions, optionally, the adjusting assembly comprises: a pull rod arranged in the hollow cavity, the pull rod being movably arranged in the mounting frame, the pull rod having a size-gradually-changing slope, the size-gradually-changing slope being used for abutting against one end of the latch, the other end of the latch being arranged in the third limiting hole; and an elastic member arranged in the hollow cavity, one end of the elastic member abutting against the mounting frame, the other end of the elastic member abutting against the latch, the elastic member being used for driving the latch to abut against the size-gradually-changing slope; wherein, in the process that the pull rod moves relative to the mounting frame, different positions of the size-gradually-changing slope abut against the latch, so as to make the latch move between the first limit position and the second limit position.

[0011] In the technical solution, the latch is driven to move relative to the mounting frame between the second limit position and the first limit position by the pull rod, so that the column body can be in a locked state or an unlocked state. This design does not need the staff to directly disassemble and assemble a plurality of bolt members, but only needs to operate the pull rod, which is simple, convenient and fast, and is helpful to improve the disassembly and assembly efficiency of the crash barrier body.

[0013] In the technical scheme, the staff manually or through a tool rotates the tongue lock outside the column body, the tongue lock drives the tongue plate to rotate, the tongue plate drives the pull rod to move relative to the mounting frame, and the pull rod drives the bolt to move relative to the mounting frame between the second limit position and the first limit position, so that the column body is in the locked state or the unlocked state. This design is simple, convenient and fast, and is beneficial to improve the disassembly and assembly efficiency of the anti-collision column body.

[0014] In some technical schemes, optionally, the adjusting assembly further comprises a connecting plate arranged in the hollow cavity, one end of the connecting plate is rotationally connected with the tongue plate, and the other end of the connecting plate is rotationally connected with the pull rod.

[0015] In the technical scheme, by arranging the connecting plate, on the one hand, the position of the tongue lock can be adjusted, and the staff can operate the tongue lock in a more comfortable position, which is beneficial to improve the user experience; on the other hand, the flexibility of the adjusting assembly as a whole can be improved, and movement interference can be avoided.

[0016] In some technical schemes, optionally, the movable anti-collision column further comprises a first guide plate arranged in the hollow cavity, the first guide plate is connected with the mounting frame, and a first guide hole is arranged on the first guide plate; wherein the pull rod is arranged in the first guide hole.

[0017] In the technical scheme, by arranging the first guide plate and the first guide hole, the guiding effect can be achieved, and the movement range can also be limited, so that the movement of the pull rod relative to the mounting frame is more stable.

[0018] In some technical schemes, optionally, the cross section of the pull rod is rectangular, and the cross section of the first guide hole is rectangular; the size of the first guide hole in the first direction is greater than the size of the pull rod in the first direction; the size of the first guide hole in the second direction is greater than the size of the pull rod in the second direction; and the first direction is perpendicular to the second direction.

[0019] In the technical scheme, by arranging the first guide hole with a size greater than the size of the pull rod, on the one hand, the installation error can be eliminated; on the other hand, during the movement of the pull rod relative to the mounting frame, there will be a certain degree of left-right or front-back movement, and this design can limit the movement range and effectively avoid movement interference.

[0020] In some technical schemes, optionally, the movable anti-collision column further comprises a second guide plate arranged in the hollow cavity, the second guide plate is connected with the mounting frame, and a second guide hole is arranged on the second guide plate; wherein the bolt is arranged in the third limiting hole and the second guide hole.

[0022] In some technical schemes, optionally, the bolt comprises a first part and a second part connected together; the first part is a cylinder, and the second part is a cylinder; the diameter of the first part is larger than that of the second part; the first part is arranged in the second guide hole, and the second part is arranged in the third limiting hole; one end of the first part, which is away from the second part, abuts against the size-gradually-changing inclined surface; when the bolt is in the second limit position, the second part can be arranged in the third limiting hole, the second limiting hole and the first limiting hole, so as to lock the position of the column body.

[0023] In the technical scheme, the structure of the bolt is optimized, the first part is arranged in the second guide hole, and the second part is arranged in the third limiting hole, so that movement of the bolt relative to the mounting frame is more stable.

[0024] In some technical schemes, optionally, the elastic member is sleeved on the bolt; the wall surface, at which the first part and the second part are connected, is a stepped surface; one end of the elastic member abuts against the mounting frame, and the other end of the elastic member abuts against the stepped surface.

[0025] In the technical scheme, the connection structure between the elastic member and the bolt is optimized, so that the bolt always abuts against the size-gradually-changing inclined surface under the elastic force of the elastic member. By changing the relative position between the pull rod and the mounting frame, the relative position between the bolt and the mounting frame can be changed.

[0026] In some technical schemes, optionally, the box body comprises a base plate, an outer box body arranged on one side of the base plate, and an inner box body arranged in the outer box body, wherein the inner box body comprises a mounting cavity.

[0027] In the technical scheme, the inner box body and the outer box body are arranged, so that, on the one hand, the contact area between the box body and the ground or the concrete base can be further increased, and the anti-collision effect is improved; and on the other hand, the weight of the box body can be reduced, and the material cost is reduced.

DETAILED DESCRIPTION

[0053] In order to enable a more complete understanding of the above-mentioned objects, features and advantages of the embodiments of the present application, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0054] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, embodiments of the present application can be practiced without the specific details, other than in the examples, and it is understood that the scope of the present application is not limited to the details below.

[0055] The anti-collision column is a general term for columnar roadblocks, which are usually made of rubber, PVC (Polyvinyl Chloride) or steel pipes, and have good warning and anti-collision functions. They are mainly installed in places such as shopping malls, junctions, highways and communities.

[0056] In related technologies, the anti-collision column structure includes an anti-collision column base (such as a ground or a concrete base) and an anti-collision column body, and the anti-collision column body is usually fixedly connected with the anti-collision column base. The limitation of this design is that, on the one hand, the anti-collision column body has limited buffering capacity when it is hit, and the anti-collision effect is poor; on the other hand, the fixed connection mode is not convenient for daily maintenance or replacement of the anti-collision column body, increasing the use and management cost.

[0057] The present application aims to provide an active anti-collision column, which has the advantages of:

[0058] In the first aspect, the detachable connection between the column body and the box can be achieved through the cooperation of the adjusting assembly and the latch. The latch is driven by the adjusting assembly to move relative to the mounting frame between the second limit position and the first limit position, so that the column body can be in a locked state or an unlocked state. When the latch is in the first limit position, the latch is only provided in the third limiting hole, and at this time the column body is not in the locked state, so that the worker can install or disassemble the column body; when the latch is in the second limit position, the latch is provided in the third limiting hole, the second limiting hole and the first limiting hole at the same time, and at this time the column body is in the locked state (the column body is fixed relative to the box). This design facilitates the daily maintenance or replacement of the anti-collision column body, which is conducive to reducing the use and management cost.

[0059] In the second aspect, the anti-collision column body can cooperate with boxes at different positions, which is conducive to flexible adjustment of the position of the anti-collision column body, and the anti-collision column body has stronger universality and wider application range.

[0060] In the third aspect, at least a part of the column body is arranged in the mounting cavity, and the outer wall of the column body abuts against the cavity wall of the mounting cavity. This design does not require the column body to be directly embedded in the ground or the concrete base, but the box is connected with the ground or the concrete base, which is conducive to increasing the contact area with the ground or the concrete base and improving the anti-collision effect.

[0061] In related technologies, the anti-collision column body is fixed to the ground by bolts. In order to improve the anti-collision effect, the number of bolts is usually more than one, such as six or eight, which makes the process of disassembling and assembling the anti-collision column body by the worker very cumbersome.

[0062] In the technical solution defined in the application, the locking state or the unlocking state of the column body can be achieved by adjusting the movement of the plug between the second limit position and the first limit position relative to the mounting frame. In this design, the staff does not need to directly disassemble and assemble the plurality of bolt members, but only needs to operate the adjusting assembly, which is simple and convenient, and is beneficial to improve the disassembly and assembly efficiency of the movable crash column body.

[0063] Reference will be made to Figures 1 to 22 The movable crash column provided according to some embodiments of the application is described below.

[0064] In one embodiment of the application, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 9 、 Figure 14 and Figure 18 , the movable crash column 1 comprises a box body 10, a column body 11, a mounting frame 131, a plug 14 and an adjusting assembly 15.

[0065] The box body 10 comprises a mounting cavity 1041, and a first limit hole 1042 is arranged on the cavity wall of the mounting cavity 1041. The column body 11 comprises a hollow cavity 111, and the column body 11 is provided with a second limit hole 112 which is in communication with the hollow cavity 111. At least a part of the column body 11 is arranged in the mounting cavity 1041, and the second limit hole 112 is arranged in correspondence with the first limit hole 1042.

[0066] The mounting frame 131 is arranged in the hollow cavity 111 and connected with the cavity wall of the hollow cavity 111. The mounting frame 131 is provided with a third limit hole 1313 which is arranged in correspondence with the second limit hole 112.

[0067] The plug 14 is movably arranged in the mounting frame 131. The plug 14 has a first limit position and a second limit position. When the plug 14 is in the first limit position, it is arranged in the third limit hole 1313. When the plug 14 is in the second limit position, it is arranged in the third limit hole 1313, the second limit hole 112 and the first limit hole 1042 to lock the position of the column body 11.

[0068] The adjusting assembly 15 is arranged in the mounting frame 131 and the column body 11, and abuts against the plug 14. The adjusting assembly 15 is used to drive the plug 14 to move between the first limit position and the second limit position.

[0069] The box 10 mainly serves as a mounting carrier relative to the column body 11. The column body 11 can be understood as a bollard body. The column body 11 is a columnar structure with a hollow cavity 111. Generally, at least a part of the box 10 is embedded in the ground or a concrete base. In the technical scheme of the present application, the column body 11 does not need to be directly embedded in the ground or the concrete base, but is connected with the ground or the concrete base through the box 10, which is beneficial to increase the contact area with the ground or the concrete base and improve the anti-collision effect.

[0070] When the column body 11 is installed in place, the second limiting hole 112 is arranged corresponding to the first limiting hole 1042.

[0071] The column body 11 mainly serves as a mounting carrier relative to the mounting frame 131. When the mounting frame 131 is installed in place, the third limiting hole 1313 is arranged corresponding to the second limiting hole 112.

[0072] By adjusting the movement of the plug 14 between the second limit position and the first limit position relative to the mounting frame 131 through the adjusting assembly 15, the column body 11 can be in a locked state or an unlocked state. When the plug 14 is in the first limit position, the plug 14 is only arranged in the third limiting hole 1313, at this time, the column body 11 is not in the locked state, and the worker can install or disassemble the column body 11; when the plug 14 is in the second limit position, it is arranged in the third limiting hole 1313, the second limiting hole 112 and the first limiting hole 1042 at the same time, at this time, the column body 11 is in the locked state (the column body 11 is fixed relative to the box 10).

[0073] Optionally, the adjusting assembly 15 can move and / or rotate relative to the mounting frame 131, or the adjusting assembly 15 can move and / or rotate relative to the column body 11.

[0074] The present application aims to provide a movable bollard 1, which has the following advantages:

[0075] In the first aspect, the detachable connection between the column body 11 and the box body 10 can be achieved by adjusting the cooperation between the adjusting assembly 15 and the latch 14. The column body 11 can be in the locked state or the unlocked state by driving the latch 14 to move relative to the mounting frame 131 between the second limit position and the first limit position through the adjusting assembly 15. When the latch 14 is in the first limit position, the latch 14 is only arranged in the third limiting hole 1313, and at this time, the column body 11 is not in the locked state, and the staff can install or disassemble the column body 11; when the latch 14 is in the second limit position, the latch 14 is arranged in the third limiting hole 1313, the second limiting hole 112 and the first limiting hole 1042 at the same time, and at this time, the column body 11 is in the locked state (the column body 11 is fixed relative to the box body 10). This design facilitates the staff to maintain or replace the anti-collision column body, and is conducive to reducing the use and management cost.

[0076] In the second aspect, the anti-collision column body can cooperate with the box body 10 in different positions, which is conducive to flexibly adjusting the position of the anti-collision column body, and the anti-collision column body has higher universality and wider application range.

[0077] In the third aspect, at least a part of the column body 11 is arranged in the mounting cavity 1041, and the outer wall of the column body 11 abuts against the cavity wall of the mounting cavity 1041. This design does not require the column body 11 to be directly embedded in the ground or the concrete base, but the box body 10 is connected with the ground or the concrete base, which is conducive to increasing the contact area with the ground or the concrete base and improving the anti-collision effect.

[0078] It should be noted that the column body 11 can be in the locked state or the unlocked state by driving the latch 14 to move relative to the mounting frame 131 between the second limit position and the first limit position through the adjusting assembly 15. This design does not require the staff to directly disassemble or assemble a plurality of bolt members, but only needs to operate the adjusting assembly 15, which is simple, convenient and fast, and is conducive to improving the disassembly and assembly efficiency of the anti-collision column body.

[0079] In some embodiments, optionally, the box body 10 can be in any shape, such as a cube, a cuboid, a cylinder and a circular truncated cone, etc. When the box body 10 is a cube or a cuboid, the cross-sectional shape of the box body 10 is rectangular (quadrilateral); when the box body 10 is a cylinder or a circular truncated cone, the cross-sectional shape of the box body 10 is circular. The shape of the box body 10 can be flexibly set according to actual needs.

[0080] Optionally, the cross-sectional shape of the column body 11 can be in any shape, such as a triangle, a quadrilateral, a circle and an ellipse, etc. When the cross-sectional shape of the column body 11 is a quadrilateral, the column body 11 is a square tube structure; when the cross-sectional shape of the column body 11 is a circle, the column body 11 is a circular tube structure.

[0081] It is to be noted that the cross-sectional shape of the mounting cavity 1041 is adapted to the cross-sectional shape of the columnar body 11. For example, in the case where the cross-sectional shape of the columnar body 11 is triangular, the cross-sectional shape of the mounting cavity 1041 is also triangular; in the case where the cross-sectional shape of the columnar body 11 is quadrangular, the cross-sectional shape of the mounting cavity 1041 is also quadrangular; in the case where the cross-sectional shape of the columnar body 11 is circular, the cross-sectional shape of the mounting cavity 1041 is also circular; and in the case where the cross-sectional shape of the columnar body 11 is elliptical, the cross-sectional shape of the mounting cavity 1041 is also elliptical.

[0082] In one specific embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 , the box 10 is a cube or a cuboid, and the columnar body 11 is a square tube structure. The cross-sectional shape of the box 10 is quadrangular, the cross-sectional shape of the mounting cavity 1041 is quadrangular, and the cross-sectional shape of the columnar body 11 is quadrangular. At least a portion of the columnar body 11 is disposed in the mounting cavity 1041.

[0083] In one specific embodiment, as shown in Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 , the box 10 is a cube or a cuboid, and the columnar body 11 is a circular tube structure. The cross-sectional shape of the box 10 is quadrangular, the cross-sectional shape of the mounting cavity 1041 is circular, and the cross-sectional shape of the columnar body 11 is circular. At least a portion of the columnar body 11 is disposed in the mounting cavity 1041.

[0084] In one specific embodiment, as shown in Figure 14 , Figure 15 , Figure 16 and Figure 17 , the box 10 is a cylinder, and the columnar body 11 is a circular tube structure. The cross-sectional shape of the box 10 is circular, the cross-sectional shape of the mounting cavity 1041 is circular, and the cross-sectional shape of the columnar body 11 is circular. At least a portion of the columnar body 11 is disposed in the mounting cavity 1041.

[0085] In one specific embodiment, as shown in Figure 18 , Figure 19 , Figure 20 and Figure 21 , the box 10 is a cylinder, and the columnar body 11 is a square tube structure. The cross-sectional shape of the box 10 is circular, the cross-sectional shape of the mounting cavity 1041 is quadrangular, and the cross-sectional shape of the columnar body 11 is quadrangular. At least a portion of the columnar body 11 is disposed in the mounting cavity 1041.

[0086] In some embodiments, as shown in Figure 2 The dimension of the box 10 in the third direction c is optionally one fifth to two fifths of the dimension of the columnar body 11 in the third direction c. Optionally, the third direction c is the height direction of the box 10 or the height direction of the columnar body 11.

[0087] By limiting the range of the dimension of the box 10 in the third direction c, on the one hand, the dimension can be prevented from being too small, ensuring that the columnar body 11 has a large enough contact area with the mounting cavity 1041 of the box 10, and the anti-collision effect of the movable anti-collision column 1 is good; on the other hand, the dimension can be prevented from being too large, which is conducive to reducing the difficulty of disassembling the columnar body 11 by the worker and improving the disassembling efficiency.

[0088] In a specific embodiment, the dimension of the box 10 in the third direction c is one fifth of the dimension of the columnar body 11 in the third direction c.

[0089] In a specific embodiment, the dimension of the box 10 in the third direction c is two fifths of the dimension of the columnar body 11 in the third direction c.

[0090] In some embodiments, as shown in

[0091] Since the first limiting hole 1042 is arranged on the inner wall of the mounting cavity 1041, the worker is not easy to quickly find the position of the first limiting hole 1042, and after the columnar body 11 is installed to the position, the second limiting hole 112 may not be aligned with the first limiting hole 1042. In this case, the worker needs to pull out the columnar body 11 and reinstall the columnar body 11 until the second limiting hole 112 is aligned with the first limiting hole 1042.

[0092] By arranging the first identification part, the worker can quickly determine the position of the first limiting hole 1042, which is conducive to the assembly efficiency of the columnar body 11 and avoids the case of incorrect installation.

[0093] It should be noted that the second limiting hole 112 penetrates the outer wall and the inner wall (the cavity wall of the hollow cavity 111) of the columnar body 11, so the worker does not need to arrange an identification part on the columnar body 11, and can quickly find the position of the second mounting hole.

[0094] In some embodiments, as shown in Figure 1 and Figure 2 The movable anti-collision column 1 further includes a tail plate 12. The tail plate 12 is arranged at the top of the columnar body 11 to block the hollow cavity 111, mainly playing a role of waterproofing and dustproofing.

[0102] In the case that the number of the first limiting holes 1042, the number of the second limiting holes 112, the number of the third limiting holes 1313 and the number of the bolts 14 are two or more, each bolt 14 is correspondingly provided with one third limiting hole 1313, one second limiting hole 112 and one first limiting hole 1042.

[0103] It should be noted that the number of the adjusting assemblies 15 is one. The workers can simultaneously drive two or more bolts 14 to move by operating one adjusting assembly 15. In this design mode, the workers do not need to directly disassemble and assemble a plurality of bolt pieces, but only need to operate the adjusting assembly 15, which is simple, convenient and fast, and is beneficial to improving the disassembly and assembly efficiency of the anti-collision column body.

[0104] In a specific embodiment, the number of the first limiting holes 1042, the number of the second limiting holes 112, the number of the third limiting holes 1313 and the number of the bolts 14 are all two.

[0105] Two first limiting holes 1042 are arranged at opposite positions of the mounting cavity 1041. For example, in the case that the cross-sectional shape of the mounting cavity 1041 is quadrangular, one of the first limiting holes 1042 is arranged on one side cavity wall of the mounting cavity 1041, and the other first limiting hole 1042 is arranged on the other side cavity wall of the mounting cavity 1041.

[0106] Two second limiting holes 112 are arranged at opposite positions of the column body 11. For example, in the case that the cross-sectional shape of the column body 11 is quadrangular, one of the second limiting holes 112 is arranged on one side wall of the column body 11, and the other second limiting hole 112 is arranged on the other opposite side wall of the column body 11.

[0122] The elastic piece 152 is arranged in the hollow cavity 111, one end of the elastic piece 152 abuts against the mounting frame 131, and the other end of the elastic piece 152 abuts against the bolt 14. The elastic piece 152 is used to drive the bolt 14 to abut against the size-gradually-changing inclined surface 1511. By arranging the elastic piece 152, the bolt 14 can always be in contact with the size-gradually-changing inclined surface 1511 under the elastic force of the elastic piece 152.

[0123] During movement of the pull rod 151 relative to the mounting frame 131, different positions of the size-gradually-changing inclined surface 1511 abut against the bolt 14, so as to move the bolt 14 between the first limit position and the second limit position.

[0128] In one specific embodiment, the elastic member 152 is a spring, and the spring is sleeved on the bolt 14.

[0129] In one specific embodiment, the elastic member 152 is a rubber block having an elastic deformation capability.
