Atraction coupler assembly 100 of the utility model will be describedin detail in combination with the specific embodiment shown in the accompanying drawings below. Therein, it should be noted that the direction of the light group along the length direction of the light tower is defined as the front end of the light tower, and the direction of the body of the light tower is the rear end of the light tower.
Atraction coupler assembly 100 according to an embodiment of the present utility model will be described below with reference to Figs. 1-11, including a first traction mechanism 1 and a second traction mechanism 2. It should be noted that the traction coupler assembly 100 in the present utility model is used to realize the traction connection between two adjacent light towers 200. For example, the first traction mechanism 1 is used to connect with one light tower 200 in two adjacent light towers 200, and the second traction mechanism 2 is used to connect with the otherlight tower 200 in two adjacent light towers 200, and the first traction mechanism 1 is connected and mated with the second traction mechanism 2.
The first traction mechanism 1 is provided with a first connection portion 11 and a mating part 12, the first connection portion 11being used to detachably connect with theone light tower 200. Therein, the first connection portion 11 is located at one end of the first traction mechanism 1, and the mating part 12 is  located at the other end of the first traction mechanism 1, as shown in Figs. 2, 3 and 4. The first connection portion 11 is located at the front end of the first traction mechanism 1 for connecting with the onelight tower 200, and the mating part 12 is located at the rear end of the first traction mechanism 1 for connecting with the second traction mechanism 2. As shown in Fig. 2, the front end of the first traction mechanism 1, that is, the end where the first connection portion 11 is located, is connected with theone light tower 200, and the first connection portion 11is designed as a structure that is detachably connected with onelight tower 200, such as a hole structure connected by bolts, which can ensure the convenience of installing the light tower 200 and the traction coupler assembly 100, so as to improve the installation efficiency.
The second traction mechanism 2 is provided with a second connecting portion 21 and a mating portion 22, the second connecting portion 21 being detachably connected with the otherlight tower 200. A sleeve space is formed in the mating portion 22, and the mating portion 22 sleeveswith the mating part 12 so that at least part of the mating part 12 is located within the sleeve space.
It should be noted that the second connecting portion 21 is located at one end of the second traction mechanism 2, and the mating portion 22 is located at the other end of the second traction mechanism 2. As shown in Figs. 4 and 10, the mating portion 22 provided at the front end of the second traction mechanism 2 is formedwith thesleeve space for connecting and mating with the mating part 12 of the first traction mechanism 1, so that at least part of the mating part 12 is located within the sleeve space, and the second connecting portion 21 is located atthe rear end of the second traction mechanism 2, and the second connecting portion 21 is used to detachably connect with the other light tower 200. Therefore, the second connecting portion 21 is provided to detachably connected with the otherlight tower 200, such as a hole structure connected by bolts, which ensures the convenience of installing the other light tower 200 with the traction coupler assembly 100 and improves the installation efficiency.
It can be understood that when two adjacentlight towers 200 are connected, as shown in Fig. 11, a plurality of light towers 200 can be connected in series in sequence, wherein one light tower 200 of two adjacent light towers 200 is located in the front and the other light tower 200 is located in the rear, and the mating portion 22 and the mating part 12 are limited and mated in the front-rear direction, so that one light tower 200 located in the front can drive the other light tower200 located in the rear forward through the traction coupler assembly 100, so as to  improve transportation efficiency. By analogy, countless light towers 200 can be towed, so that a plurality of light towers 200 can be transported at the same time, and the transportation efficiency of light towers 200 is improved.
According to the traction coupler assembly 100 of the embodiment of the utility model, adjacent light towers 200 can be connected in series by using the traction coupler assembly 100, so that a plurality of light towers 200 can be transported at the same time, and each traction mechanism is connected with the light tower 200 by bolts when detachably connected with the light tower 200, so that the installation is convenient and the operation is not difficult, so as to reduce the labor cost and improve the transportation efficiency.
In some embodiments, the sleeve space is open downward at the mating portion 22, and at least part of the mating part 12 protrudes upwards from the first traction mechanism 1 and extends into the sleeve space.
It should be noted that the mating part 12 is provided to protrude upward relative to the first traction mechanism 1, and the mating portion 22 forms thesleeve space that is open downward, and the mating portion 22 sleeveswith the mating part 12 so that at least part of the mating part 12 is located within the sleeve space.
That is to say, the mating part 12 is configured to protrude upward from the first traction mechanism 1, and at the same time, the sleeve space of the mating portion 22 is open downward. As shown in Fig. 3, during actual connection, the mating portion 22 can sleevewith the mating part 12 so that the mating part 12 is located within the sleeve space, so that the mating portion 22 and the mating part 12 can be mated and limited in the front-rear direction.
In some embodiments, the mating part 12 includes a fixing portion 121 and a first limiting portion122. The fixing portion 121 is connected with the first traction mechanism 1, and the first limiting portion122 is connected with the upper end of the fixing portion 121 extending into the sleeve space.
In some embodiments, the fixing portion 121 can be installed in the first traction mechanism 1, and a connecting hole D (not shown in Figs. 4-6) can be provided on the first traction mechanism 1. The connecting hole D passes through the first traction mechanism 1, and the fixing portion 121 can be inserted into the connecting hole D, and the first limiting portion122 is located above the fixing portion 121 for matingwith the sleeve space of the mating portion 22 of the second traction mechanism 2. Therein, when the mating part 12 is replaced, the fixing portion 121 is pulled out from the connecting hole D of the first traction  mechanism 1, which is simple in structure and convenient to install.
In some embodiments, the sleeve space is configured as a snap-in slot A, and the snap-in slot A has an opening at one end away from the first traction mechanism 1, and the first limiting portion122 is adapted to extend into the snap-in slot A along the opening.
As shown in Figs. 4-6, the mating portion 22 is configured as a hood 221, and the sleeve space is configured as a snap-in slot A that opens downward from the hood 221, and the opening width of the snap-in slot A of the hood 221 is adapted to the first limiting portion122 of the mating part 12, so that the first limiting portion122 can extend into the snap-in slot A, and the snap-in slot A is in a closed state at one end of the hood 221 near the first traction mechanism 1. As shown in Fig. 4, the front end of the snap-in slot A is in a closed state, so that after the first limiting portion122 is located within the snap-in slot A, the inner end surface of the closed end of the snap-in slot A abuts against the outer wall surface of the first limiting portion122, so as to transfer the traction force between the first traction mechanism 1 and the second traction mechanism 2 and realize the reliable connection between two adjacent light towers 200.
In some embodiments, the first limiting portion122 is configured as spherical-shaped, and the diameter of the first limiting portion122 is larger than the lower opening width of the snap-in slot A and smaller than the opening width of the opening.
It should be noted that, as shown in Fig. 4, the fixing portion 121 in the mating part 12 is configured as a rod-shaped structure, and the first limiting portion122 is configured as a spherical structure, and the diameter of the first limiting portion122 is larger than the diameter of the cross section of the fixing portion 121.
That is to say, the first limiting portion122 can be clamped in the snap-in slot A, and since the diameter of the first limiting portion122 is larger than the lower opening width of the snap-in slot A, the first limiting portion122 cannot be easily separated from the snap-in slot A, so as to ensure its limiting ability, and the diameter of the first limiting portion122 is smaller than the opening width of the opening, whichcan ensure that the first limiting portion122 can extend into the snap-in slot A.
It can be understood that designing the diameter of the first limiting portion122 to be larger than the fixing portion 121 can ensure the limiting between the first limiting portion122 and the first traction mechanism 1, so that  the first limiting portion122 will not fall off the first traction mechanism 1, and the sleeve space between the first limiting portion122 and the mating portion 22 can be guaranteed to have a higher degree of combination, that is, the contact area of the first limiting portion122 abutting against the inner wall of the sleeve space can be increased, so as to improve the efficiency.
Therefore, by the design that the upper opening width of the snap-in slot A is large and the lower opening width is small, the sufficient limiting and mating with the first limiting portion122 is achieved for the snap-in slot A, so that the traction force can be transferred between the first traction mechanism 1 and the second traction mechanism 2, and the mating connection between two adjacent light towers 200 is realized.
In some embodiments, the fixing portion 121 is detachably connected with the first traction mechanism 1.
It should be noted that the first traction mechanism 1 includes a connecting hole D and is used to be detachably connected with the fixingportion 121, so that the fixing portion 121 can be flexibly attached to and/or detached from the first traction mechanism 1, therefore the fixing portion 121 can be stably installed on the first traction mechanism 1, and the connection stability of the fixing portion 121 on the first traction mechanism 1 is ensured, thereby the whole fixing portion 121 is not easy to shake and tilt, and it is beneficial to replace and maintain the fixing portion 121 during the subsequent use.
In some embodiments, the fixing portion 121 is configured as rod-shaped, and the first traction mechanism 1 is provided with a traction plate 142 with a connecting hole D, and the fixing portion 121 detachably passes through the connecting hole D.
It should be noted that the fixing portion 121 in the mating part 12 is configured as a rod-shaped structure, and the lower end of the fixing portion 121 is provided with a threaded structure, and the outer peripheral wall of the fixing portion 121 is also provided with a limiting protrusion portion 123, which is located above the threaded structure. As shown in Fig. 4, the limiting protrusion portion 123 is provided on the peripheral wall of the middle part of the fixing portion 121 in the length direction, and is configured as an annular support platform, and is spaced apart from the first limiting portion122, wherein a certain length is formed between the limiting protrusion portion 123 and the lower end of the fixing portion 121.
In addition, the traction plate 142 in the first traction mechanism 1 is  configured as a rectangular plate, and the connecting hole D mated with the fixing portion 121 is provided in the traction plate, wherein, as shown in Fig. 10, the end of the traction plate 142 near the second traction mechanism 2 is provided with the connecting hole D passing through the up-down direction, and the connecting hole D is configured as a circular hole.
In practice, the lower end of the fixing portion 121 can pass through the connecting hole D, so that the end at the lower end of the fixing portion 121 is screwed with the nut B at the lower side of the traction plate 142, while the limiting protrusion portion 123 is supported on the upper surface of the traction plate 142. With the further tightening of the nut B and the fixing portion 121, the nut B and the limiting protrusion portion 123 are pressed against both sides of the traction plate 142, so that the mating part 12 is stably installed on the traction plate 142.
That is to say, when the fixing portion 121 passes through the connecting hole D and forms a screwed connection with the connecting hole D, the fixing portion 121 can be detachably connected with the first traction mechanism 1, so that the fixing portion 121 and the first traction mechanism 1 can be assembled and disassembled more conveniently and quickly, and the convenience of assembly can be improved.
It should be noted that the outer diameter of the limiting protrusion portion 123 is slightly smaller than the width of the sleeve space in the mating portion 22, so thatthe mating depth between the sleeve space and the mating part 12 is ensured, in addition to the sleeve space can cover the mating part 12 to the greatest extent, and improve the connection stability of the first traction mechanism 1 and the second traction mechanism 2.
When the fixing portion 121 passes through the traction plate 142 and is connected with the nut B, the limiting protrusion portion 123 can play the role of limiting and supporting the whole mating part 12, so that a larger part of the fixing portion 121 is located above the traction plate 142, so that the first limiting portion122 and the larger part of the fixing portion 121 can be sleeved in the sleeve space, which increases the sleeved depth and improves the connection stability.
In some embodiments, the sleeve spacepasses through the mating portion 22 in the up-down direction, and the mating part 12 passes through the sleeve space. Therefore, the mating portion 22 can sleeveon the mating part 12 from top to bottom, so that at least part of the mating part 12 can be limited within the sleeve  space, and then the mating part 12 can be fastened with nuts to achieve detachable connection, and when the mating part 12 abuts against the inner wall of the sleeve space, the mating portion 22 and the mating part 12 can be limited in the front-rear direction. And/or, as shown in Fig. 9, during actual connection, the mating part 12 can be inserted into the mating portion 22 from top to bottom, so that at least part of the mating part 12 abuts against the sleeve space, so that the mating portion 22 and the mating part 12 are limited in the front-rear direction.
In some embodiments, the mating part 12 includes thefixing portion 121 and a second limiting portion124, the second limiting portion124 is connected to the upper end of the fixing portion 121, the fixing portion 121 passes through the sleeve space to be connected with the first traction mechanism 1, and the second limiting portion124 is limited and pressed against the upper side of the mating portion 22.
It should be noted that the lower part of the outer peripheral wall of the second limiting portion124 is fixed and connected with the upper end of the fixing portion 121, for example, they are fixedly connected into one piece, and they can be connected by welding.
It can be understood that the fixing portion 121 is connected with the first traction mechanism 1, for example, the fixing portion 121 is detachably installed in the first traction mechanism 1, and the second limiting portion124 is located above the first traction mechanism 1 for being mated with the sleeve space of the mating portion 22 of the second traction mechanism 2. When the mating part 12 is replaced, the fixing portion 121 can be pulled out from the first traction mechanism 1, which is simple in structure and convenient to install.
In some embodiments, both the mating portion 22 and the second limiting portion124 are configured as annular-shaped, the fixing portion 121 passes through the inner hole of the mating portion 22, and the outer diameter of the second limiting portion124 is larger than the hole diameter of the inner hole of the mating portion 22.
It should be noted that, as shown in Figs. 9 and 10, the second limiting portion124 is configured as annular-shaped, the second limiting portion124 is vertically placed, while the mating portion 22 is configured as a snap ring 222, wherein the snap ring 222 is configured as annular-shaped and horizontally placed.
The inner diameter of the snap ring 222 is smaller than the outer diameter of the second limiting portion124, and the inner diameter of the snap ring 222 is  larger than the outer diameter of the fixing portion 121. That is, the fixing portion 121 can pass through the snap ring 222, but the second limiting portion124 cannot pass through the snap ring 222, so that the snap ring 222 cannot come off from the mating part 12, and the effective connection between the first traction mechanism 1 and the second traction mechanism 2 is realized, which is simple in structure and convenient to install.
In some embodiments, the fixing portion 121 is configured as rod-shaped, and the first traction mechanism 1 is provided with a traction sleeve 141, and the fixing portion 121 passes through the sleeve spacewith the lower end beinginserted into the traction sleeve 141.
It should be noted that, as shown in Fig. 5, the traction sleeve 141 can be configured as a hollow rectangular cylinder with an upward opening, so as to form an installation space in the traction sleeve 141. The traction plate 142 connected with the traction sleeve 141 is configured as a rectangular plate, the width of the traction plate 142 is larger than the width of the bottom end of the traction sleeve 141, and the traction sleeve 141 is located at one end of the traction plate 142 far from the second traction mechanism 2.
It can be understood that the traction plate 142 and the traction sleeve 141 can be connected by a connecting structure, or integrally formed, or the traction sleeve 141 is directly welded above the traction plate 142 as shown in Fig. 4.
The traction plate 142 extends in a direction close to the second traction mechanism 2 relative to the traction sleeve 141, and the mating part 12 is detachably installed on the traction sleeve 141, so that when the mating part 12 is installed with the traction sleeve 141, the lower end part of the fixing portion 121 can be inserted into the traction sleeve 141, and the height of the upper end of the fixing portion 121 is higher than that of the upper end of the traction sleeve 141. The second limiting portion124 is connected to the upper end of the fixing portion 121, and the outer diameter of the second limiting portion124 is larger than the width of the inner cavity of the traction sleeve 141, so that the second limiting portion124 is supported above the traction sleeve 141.
In other words, when the mating part 12 and the mating portion 22 are connected and mated, firstly, the snap ring 222 can be extended above the traction sleeve 141, and the inner hole of the snap ring 222 is aligned with the upper end of the inner cavity of the traction sleeve 141, and then the fixing portion 121 is inserted into the inner hole of the snap ring 222 and extended into the traction sleeve 141, and the second limiting portion124 is supported on the snap ring  222, so that the snap ring 222 will not escape from the mating part 12, and the effective connection between the first traction mechanism 1 and the second traction mechanism 2 is realized, which is simple in structure and convenient to install.
In some embodiments, a connecting block 223 can be provided on the second traction mechanism 2, and one side edge of the snap ring 222 is connected with the connecting block 223. The connecting block 223 is configures as a stepped rectangular plate, and the connecting block 223 is connected and fixed with one side edge of the snap ring 222 by welding or other means, so as to enhance the structural stability of the second traction mechanism 2.
In some embodiments, both ends of the traction sleeve 141 are open and one end region of the traction plate 142 is supported at the lower end of the traction sleeve 141, the lower end of the fixing portion 121 extends into the traction sleeve 141 and is supported at the one end region of the traction plate 142, and at least part of the second traction mechanism 2 is supported above the other end region of the traction plate 142.
As shown in Fig. 9, the traction sleeve 141 is arranged on the traction plate 142 and located at one end of the traction plate 142 far away from the second traction mechanism 2. It should be noted that the upper and lower ends of the traction sleeve 141 are both open ends, and the surrounding walls at the lower end opening are connected with the traction plate 142 by welding or by other connections. The mating part 12 is detachably mated with the traction sleeve 141, for example, the fixing portion 121 of the mating part 12 can be inserted into the traction sleeve 141 from top to bottom.
In addition, the snap ring 222 is installed on the upper side of the second traction mechanism 2, and is located at one end of the upper side of the second traction mechanism 2 close to the first traction mechanism 1, so as to be sleeved on the fixing portion 121 of the mating part 12. That is, as shown in Fig. 9, the snap ring 222 sleevesand is connected with the fixing portion 121, one side edge of the snap ring 222 is connected with the connecting block 223, and the connecting block 223 is connected with the main body of the second traction mechanism 2. Therefore, as shown in Fig. 9, when the fixing portion 121 is inserted into the traction sleeve 141, the snap ring 222 at the front upper end of the second traction mechanism 2 is supported above the traction sleeve 141, and at the same time, the main part of the second traction mechanism 2 is supported at the right lower end of the traction plate 142, so as to ensure the tight connection  between the two traction mechanisms, improving the stability of the traction coupler assembly 100 and making the connection between two adjacent light towers more stable.
In some embodiments, the first traction mechanism 1 includes a connecting frame 13 and a traction frame 14, wherein the connecting frame 13 and the traction frame 14 can be provided as an integral structure to improve the connection strength between them, or the connecting frame 13 can be connected with the traction frame 14 by welding, or the connecting frame 13 can be connected with the traction frame 14 by bolts.
One end of the connecting frame 13 near the second traction mechanism 2 is connected with the traction frame 14, and a first connection portion 11 is provided on the connecting frame 13. That is, the end of the connecting frame 13 near the second traction mechanism 2, that is, the rear end of the connecting frame 13, can be connected with the traction frame 14 by bolt connection or welding. The connecting frame 13 can be detachably connected with onelight tower 200 through the first connection portion 11. As shown in Fig. 5 and Fig. 6, the first connecting portion 11 are provided in two groups, and the two groups of first connecting portion 11 are distributed apart on the connecting frame 13, so that the connecting frame 13 can be detachably connected with the light tower 200 on opposite sides, and the connection strength between the first traction mechanism 1 and the light tower 200 is improved.
Therefore, by providing the first traction mechanism 1 formed by the connecting frame 13 and the traction frame 14, the connecting frame 13 and the traction frame 14 are respectively connected with onelight tower and the second traction mechanism 2, so as to ensure that the first traction mechanism 1 can effectively connect and tow between the onelight tower and the second traction mechanism 2.
In some embodiments, the mating part 12 is installed on the traction frame 14, that is, the traction frame 14 is limited andmated with the mating portion 22 of the second traction mechanism 2 through the mating part 12, so as to realize the connection and fixation of the first traction mechanism 1 and the second traction mechanism 2. It can be understood that the mating part 12 is the main load-bearing part between the first traction mechanism 1 and the second traction mechanism 2, which is prone to structural damage or deformation after long-term use.
In some embodiments, the mating part 12 is detachably installed to the  traction frame 14. That is, in actual installation, the mating part 12 can be installed on the traction sleeve 141, so that the mating part 12 can be flexibly detached relative to the traction sleeve 141, so that when the first traction mechanism 1 and the second traction mechanism 2 are connected, the traction sleeve 141 bears the main traction force therebetween; alternatively, the mating part 12 can be installed on the traction plate 142, so that the mating part 12 can be flexibly detached relative to the traction plate 142, so that when the first traction mechanism 1 and the second traction mechanism 2 are connected, the traction plate 142 bears the main traction force therebetween.
In other embodiments, the mating portion 22 may include a hood 211 and a snap ring 222 which are spaced apart, wherein the hood 211 has a snap-in slot A which is open downward, while the snap ring 222 is configured as a horizontal hollow ring.
In addition, the mating part 12 includes a first mating part and a second mating part. Wherein, the first mating part is configured to include arod-shaped fixing portion 121and a spherical-shapedfirst limiting portion122, and the fixing portion 121 of the first mating part is detachably connected to the traction plate 142 of the first traction mechanism 1, such as being inserted into the connecting hole D of the traction plate 142; the second mating part is configured to include a rod-shaped fixing portion 121 and a ring-shaped second limiting portion124, wherein the second limiting portion124 is vertically ring-shaped and fixed at the upper end of the corresponding fixing portion 121, and the fixing portion 121 of the second mating part can be inserted into the traction sleeve 141 of the first traction mechanism 1.
In a specific installation, firstly, the fixing portion 121 of the first mating part can be fixed to the traction plate 142. At this time, the hood 211 can sleeve upon the first limiting portion122 of the first mating part, so that the first limiting portion122 can be limited and mated in the snap-in slot A. At the same time, the snap ring 222 is sleeved on the upper end of the traction sleeve 141, and the inner hole of the snap ring 222 is directly facing with the upper opening of the traction sleeve 141, and thus, the fixing portion 121 of the second mating part is inserted from the inner hole of the snap ring 222 and extended into the traction sleeve 141, so as to realize that the fixing portion 121 is limitedand mated with the snap ring 222 and the traction sleeve 141, and finally the second limit part 124 is pressed against the upper side of the snap ring 222, so as to realize the limiting and mating.
Thus, in this embodiment, the first traction mechanism 1 and the second traction mechanism 2 can be connected by two groups of limiting structures at the same time, which is beneficial to improve the connection stability.
In some embodiments, the connecting frame 13 includes two side beams 131, the first ends of which are respectively connected to the two sides of the traction sleeve 141, and the second ends of the two side beams 131 are spaced apart and each of which is provided with a first connecting part 11 to be detachably connected to the two sides of onelight tower 200 respectively, wherein the two side beams 131 are configured as groove structures that are open to each other, that is, the side beams 131 are hollow, which is beneficial to reduce the overall weight of the connecting frame 13.
Specifically, as shown in Fig. 3, each side beam 131 includes a first section and a second section, the first section and the second section are integrally formed, and the first sections of the two side beams 131 are spaced apart in parallel. One end of the second section of each of the two side beams 131 is fixed and connected with the respective first section thereof, and the other end of the second section of each of the two side beams 131 is respectively connected with the each of two side edges of the traction sleeve 141. The first section and the second section are connected by bending, so that after being connected with the traction sleeve 141, the second sections of the two side beams 131 are integrally configured into an open structure with the traction sleeve 141 as the end point.
It should be noted that the length of the first section of the side beam 131 is smaller than the length of the second section. In addition, a cross beam 132 is arranged in the middle part of the second section of the two side beams 131, and the cross beam 132 is configured as a rectangular plate, and both ends of the cross beam 132 extend into the inner grooves of the second sections of the two side beams 131, and are connected and fixed with the second sections by welding or other forms, that is, the cross beam 132 and the side beams 131 can play the role of mutual connection and support, so that the cross beam 132 can bear various lateral loads from the traction coupler assembly 100, so as to enhance the stability of the connecting frame 13.
Thus, the side beam 131 and the cross beam 132 together form the connecting frame 13, which can ensure the structural stability of the traction coupler assembly 100. And the first sections of the two side beams 131 are connected with the first connecting parts 11, which can be used for detachable connection with both sides of one light tower 200, so as to ensure the convenience  of installation.
