Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments individually or selectively.

[0033] Furthermore, the present invention is described in detail in conjunction with schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0034] Embodiment 1, refer to Figure 1 - Figure 5, which is the first embodiment of the present invention, provides a cable laying cart, including a cart 1, and a support frame 11 arranged on the cart 1;

[0035] A connecting frame 2, which is slidably arranged on the support frame 11;

[0036] When one end of the connecting frame 2 is at the bottom of the support frame 11, the cart 1 can be used to transport goods. When one end of the connecting frame 2 is at the middle position of the support frame 11, the connecting frame 2 is used as the rotating shaft of the wire reel.

[0037] Among them, the support frame 11 is vertically fixed on the cart 1, and its front surface is provided with a sliding groove 111 and a fixing groove 113 for guiding the movement of the slider 112. The sliding groove 111 is a vertically opened guiding groove that restricts the slider 112 to only slide up and down. The front end is fixed to the connecting frame 2, and the rear end is provided with a special-shaped block 114. The shape of the special-shaped block 114 matches that of the fixing groove 113 for locking the position of the slider 112. The fixing groove 113 is used to embed the special-shaped block 114 when the slider 112 rises to the highest point to achieve locking. The contour of the special-shaped block 114 is completely adapted to the fixing groove 113 to ensure no shaking after embedding. And the special-shaped block 114 is rectangular, so that after the special-shaped block 114 is embedded in the fixing groove 113, the special-shaped block 114 cannot rotate.

[0038] Further, a rotating groove 21 opened in the front part of the connecting frame 2, a movable part 22 arranged in the rotating groove 21, a receiving groove 23 opened on the lower side surface of the connecting frame 2, a support column 24 arranged in the receiving groove 23, and a sliding groove 25 opened on the movable part 22; the support column 24 passes through the sliding groove 25 and is slidably connected with the movable part 22. A limiting block 26 arranged on the support column 24, and a clamping groove 27 arranged in the receiving groove 23; the limiting block 26 is movably connected in the clamping groove 27. A limiting strip 28 is arranged on the upper side of one end of the limiting block 26; the total height of the limiting block 26 and the limiting strip 28 is greater than the height of the sliding groove 25, and this end of the limiting block 26 cannot pass through the sliding groove 25. A limiting groove 29 is opened on the upper side of the front part of the cart 1; the limiting groove 29 cooperates with the movable part 22 and the limiting block 26 respectively. When the limiting block 26 is limited in the limiting groove 29, the support column 24 and the support frame 11 form a zigzag structure;

[0039] Among them, the movable part 22 is installed in the rotation groove 21 through a rotating shaft. Restricted by the special structure of the rotation groove 21, it can only rotate counterclockwise by 90°, ensuring that the support column 24 can only be switched at a specific angle to avoid misoperation. The support column 24 is rectangular in shape and is slidably connected between the storage groove 23 and the movable part 22. A limit block 26 is provided on the support column 24, and a clamping groove 27 is provided in the storage groove 23. When the support column 24 is stored in the storage groove 23, the limit block 26 is limited in the clamping groove 27. When the support column 24 is stored, the limit block 26 snaps into the clamping groove 27 of the storage groove 23 to prevent the movable part 22 from accidentally rotating due to gravity.

[0040] A limit strip 28 is provided on the upper side of one end of the limit block 26. The total height of the limit block 26 and the limit strip 28 is greater than the height of the sliding groove 25, and one end of the limit block 26 cannot pass through the sliding groove 25, preventing the support column 24 from being overly pulled out of the movable part 22 and can also play a reminder effect. When the limit strip 28 contacts the movable part 22, it indicates that the support column 24 has reached the maximum sliding stroke and needs to be rotated to switch the direction. Rotate the movable part 22 counterclockwise by 90° to change the support column 24 from the horizontal storage state to the vertical use state. Push down the support column 24 to insert the limit block 26 into the limit groove 29 on the trolley 1. The support column 24 and the support frame 11 form a zigzag structure, which can provide an upward supporting force to the support frame 11. The upper end of the support column 24 is higher than the horizontal plane of the support frame 11 to prevent the wire reel from axially slipping off. Also, the lower end of the movable part 22 can be inserted into the limit groove 29, and this effect can be achieved in the transportation mode.

[0041] Embodiment 2, refer to Figures 2 - 5 , this embodiment is used as a carrying and moving tool for a wire reel when laying multiple cable lines. One trolley 1 can be used with multiple wire reels, and the detachable trolley 1 and wire reel can be placed separately when stored. Compared with multiple complete trolleys 1, they occupy less space. The detachable design enables construction workers to quickly replace the wire reel according to different construction requirements. For example, after completing the laying of one cable, the trolley 1 can be quickly combined with a new wire reel and immediately put into the laying work of the next cable route without waiting for the allocation of a new trolley 1, greatly shortening the construction preparation time and improving the overall construction efficiency.

[0042] Push up the connecting frame 2 to drive the slider 112 to vertically move upward along the sliding groove 111 of the support frame 11. When the slider 112 reaches the upper end of the sliding groove 111, the special-shaped block 114 aligns with the fixing groove 113, and then push the slider 112 horizontally backward to embed and fix the special-shaped block 114. At this time, the position of the connecting frame 2 is locked to form a stable zigzag structure;

[0043] Pull out the support column 24 from the storage groove 23 of the connecting frame 2 until the limiting strip 28 of the limiting block 26 contacts the movable part 22. Rotate the movable part 22 counterclockwise by 90°, so that the support column 24 changes from the horizontal storage state to the vertical use state. Push down the support column 24 to insert the limiting block 26 into the limiting groove 29 on the trolley 1. The support column 24 and the support frame 11 form a support structure to prevent the wire reel from axially slipping off.

[0044] Embodiment 3, refer to Figure 2 - Figure 5 , in this embodiment, by changing the position of the support column 24, the sacrifice of universality due to special design is avoided. The connecting frame 2 is used as a rotating shaft, which is suitable for winding and unwinding cables, ropes, etc., but will occupy the loading space of the trolley 1. When the connecting frame 2 is lowered to the bottom, the trolley 1 resumes a flat loading platform and can normally transport toolboxes, equipment, goods, etc. It can be used for multiple purposes, reducing the purchase cost of special equipment, and is also convenient for stacking and storage, adapting to the needs of different working environments, enabling the trolley to meet special operation requirements (such as cable management) and quickly return to conventional transportation tasks, realizing an efficient solution of "one trolley for two uses".

[0045] Pull up the support column 24 to disengage the limiting block 26 from the limiting groove 29 of the trolley 1. Rotate the movable part 22 clockwise by 90° to turn the support column 24 back to the horizontal state. Push the support column 24 back into the storage groove 23, and the limiting block 26 is fixed in the clamping groove 27. Pull the slider 112 horizontally forward to disengage the special-shaped block 114 from the fixing groove 113. The slider 112 resumes its vertical sliding ability and pulls down the connecting frame 2, driving the slider 112 to vertically move down along the sliding groove 111. The connecting frame 2 descends to the bottom of the support frame 11, flush with the bottom of the trolley 1, forming an "L" shape with the support frame 11, and at this time the rotating part is inserted into the limiting groove 29.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
