[0041] like Figure 1-2 As shown, the present invention provides a trolley, including a frame 10, a wheel 20 is arranged at the bottom of the frame 10, and a workbench is fixed to the frame 10 for placing tightening tools and bolts. The workbench includes a storage box 30, a bracket 40, a tool support 50, a nail removal piece 60 and a pull rope 70. Among them, an avoidance hole is opened on the top of the storage box 30, and the bolts are placed in the storage box 30; the bracket 40 is installed on the frame 10, and the bracket 40 is provided with a fixed pulley 41; the tightening tool can be placed on the tool support 50, and the tool support 50 is slidably connected to the bracket 40; the nail removing member 60 and the tool support 50 are respectively located on both sides of the fixed pulley 41, and the nail removing member 60 is located above the storage box 30, the nail removing member 60 includes a nail removing part, and the nail removing part is provided with a magnet 61, and the nail removing part can enter the storage box 30 from the avoidance hole; the pull rope 70 is slidably connected to the fixed pulley 41 along the circumference of the fixed pulley 41, and the two ends of the pull rope 70 are respectively connected to the tool support 50 and the nail removing member 60.

[0042] Assume that the mass of the nail removal member 60 is M1, the mass of the tool support 50 is M2, the mass of the screw that the nail removal member 60 can absorb at most at one time is m1, and the mass of the tightening tool is m2, which meets the following relationship: M2 <M1<M1+m1<M2+m2。

[0043] The workbench includes two states. When in the first state, the tightening tool is placed on the tool support 50. At this time, the tool support 50 is in a low position and the nail removing component 60 is in a high position. When in the second state, the nail removing component 60 is in a low position, and the nail removing part extends from the avoidance hole into the storage box 30 to absorb the screws. The tool support 50 is not loaded with a tightening tool and is in a high position.

[0044] During actual work, the trolley follows the operator to the first processing point, first takes out the screws required here from the storage box 30, and uses the tightening tool to fix the screws on the workpiece. At this time, the workbench is in the second state. After completing the fixing work at this point, the tightening tool is placed on the tool support 50. At this time, the workbench switches from the second state to the first state, and the nail taking part withdraws from the storage box 30 with the adsorbed screws. The staff moves to the second processing point with the trolley. At this time, the nail taking part 60 is in a high position, and the nail taking part adsorbs the screws. The staff takes the required screws from the nail taking part, and then removes the tightening tool to fix the workpiece. At this time, the workbench switches to the second state, and the nail taking part enters the storage box 30 to adsorb the screws. After completing the fixing work here, the staff places the tightening tool on the tool support 50, the workbench switches to the first state, and goes to the next processing point with the staff, and goes back and forth.

[0045] With such a design, the nail removing member 60 and the tool support 50 are connected by the fixed pulley 41 structure, so that the nail removing member 60 and the tool support 50 have opposite movement tendencies, and the nail removing part is provided with a magnet 61, so that it can absorb the screws, and when the workbench switches between the first state and the second state, the nail removing member 60 can complete the action of repeatedly grabbing the screws from the storage box 30, automatically loading the material, making it convenient for the staff to take it, saving working time, improving work efficiency, and effectively preventing the bolts from scratching the palms or clothes.

[0046] Optionally, the tool support 50 and the nail removal member 60 are both support rods, and the bracket 40 is also fixed with shaft sleeves corresponding to the support rods one by one, and the shaft sleeves are sleeved on the support rods and slidably connected to the support rods.

[0047] Specifically, the bracket 40 includes two guide columns 44, which are arranged at intervals along the first horizontal direction and extend in the vertical direction. One end of the guide column 44 is fixed to the frame 10, and the other end is connected by a limit rod 45. The second shaft sleeve 43 is fixed between the two guide columns 44, and the tool support 50 is sleeved in the second shaft sleeve 43 and slidably connected thereto; one of the guide columns 44 is connected to a mounting rod 46 along the first horizontal direction, and the mounting rod 46 is arranged back to back with the other guide column 44, and the end of the mounting rod 46 away from the guide column 44 is fixed A first sleeve 42 is fixed, and the nail removal member 60 is sleeved in the first sleeve 42 and slidably connected thereto. The axial directions of the first sleeve 42 and the second sleeve 43 are parallel to the vertical direction. The mounting rod 46 is provided with a support rod 47 upward in the vertical direction. The support rod 47 is located between the first sleeve 42 and the guide column 44. A fixed pulley 41 is provided on the support rod 47, and the axial direction of the fixed pulley 41 is perpendicular to the first horizontal direction. One end of the pull line is fixed to the nail removal member 60, and the other end is fixed to the tool support 50 after wrapping around the fixed pulley 41 along the circumference of the fixed pulley 41. With such a configuration, the bracket 40 constructed by the rods occupies a small space and is relatively light in weight, which reduces the load of the trolley, and has a simple structure and is convenient for maintenance.

[0048] Optionally, the nail removing member 60 is a first support rod, and the sleeve includes a first sleeve 42. A magnet 61 is arranged at one end of the first support rod close to the storage box 30, and a pull rope 70 and a first limiting protrusion 62 are fixed at the other end. The first sleeve 42 is located between the first limiting protrusion 62 and the magnet 61. In the vertical direction, the first limiting protrusion 62 can abut against the end surface of the first sleeve 42 on the side opposite to the magnet 61. In this way, when the workbench switches from the first state to the second state, the nail removing member 60 descends with gravity. When the nail removing part extends into the storage box 30 but leaves a certain distance from the bottom of the storage box 30, the first limiting protrusion 62 abuts against the first sleeve 42 to limit the descending distance of the nail removing member 60, so as to prevent the nail removing member 60 from coming out from the bottom of the first sleeve 42, and also to prevent the nail removing part from repeatedly colliding with the bottom of the storage box 30 or the screws in the storage box 30, resulting in damage to the magnet 61 at the nail removing part.

[0049] Optionally, the tool support 50 is a second support rod, the sleeve further includes a second sleeve 43, one end of the second support rod is provided with a tray 51, the other end is provided with a second limiting protrusion, the second sleeve 43 is located between the second limiting protrusion and the tray 51, the bottom surface of the tray 51 can abut against the top end surface of the second sleeve 43, and the second limiting protrusion can abut against the bottom end surface of the second sleeve 43. Since the tool support 50 is linearly related to the lifting stroke of the nail removal part, when the tool support 50 is limited in its range of motion by the tray 51 and the limiting protrusion, the range of motion of the nail removal member 60 is also limited.

[0050] Optionally, the sleeve includes a housing 421 and a roller 422, the roller 422 is rotatably connected to the housing 421, and the support rod is slidably connected to the circumferential end surface of the roller 422. In this arrangement, the roller 422 reduces the friction between the support rod and the sleeve, making the switching between the first state and the second state of the workbench smoother.

[0051] Optionally, the workbench further includes a support member 80 and an abutment member 81 arranged at intervals, the support member 80 is located at the bottom of one end of the storage box 30, and the nail removal member 60 is located at the other end of the storage box 30 and the side wall of the end can abut against the abutment member 81. After the nail removal member 60 removes nails several times, the number of screws in the storage box 30 decreases and is dispersed in the storage box 30, especially concentrated at one end away from the nail removal part in the horizontal direction. The magnetic force of the magnet 61 of the nail removal part is difficult to absorb the screws at the far end. Therefore, in order for the nail removal part to continuously absorb the screws from the storage box 30, a support member 80 is provided at the bottom of one end of the storage box 30 away from the nail removal part in the horizontal direction, so that the storage box 30 is tilted, so that the screws move toward the side where the nail removal part is located and gradually concentrate below the nail removal part. Furthermore, since the storage box 30 is tilted, in order to prevent the storage box 30 from moving toward the side away from the support member 80, the present invention is also provided with an abutment portion, which abuts against the side wall of the storage box 30 away from the support member 80 to keep the storage box 30 stable in the tilted state.

[0052] Furthermore, the support member 80 can adjust the angle between the storage box 30 and the horizontal plane. As the number of screws in the storage box 30 decreases, the tilt angle of the storage box 30 is gradually increased, so that the screws are more concentrated.

[0053] In order to facilitate the movement of the trolley between each processing point, a carrier is installed in the workshop. The carrier can pull the trolley to move and reduce the workload of the staff. After the carrier sends the trolley to the processing point, it may need to stay at the processing point for a long time to perform fixed work. In order to rationally utilize resources, the carrier will not stay at the processing point, but will perform other work, such as moving goods, or carrying other trolleys. Therefore, the convenience of the connection between the trolley and the carrier is more important.

[0054] To this end, the trolley provided by the present invention also includes a connecting rod 90, which is slidably connected to the frame 10 in the vertical direction, and the connecting rod 90 can be plugged into the mounting hole of the carrier from bottom to top in the vertical direction. In this way, when the trolley needs to carry the carrier, the connecting rod 90 is inserted into the mounting hole, so that the trolley can travel with the carrier, and after reaching the designated processing point, the connecting rod 90 is pulled out to release the connection.

[0055] Furthermore, an elastic member 91 is provided between the connecting rod 90 and the frame 10 , and the elastic member 91 enables the connecting rod 90 to have a tendency to move upward and away from the frame 10 in a vertical direction.

[0056] Preferably, the carrier is provided with a convex connection portion 902, and the connection portion 902 is provided with a mounting hole in the vertical direction. The connecting rod 90 is slidably connected to the frame 10 in the vertical direction. The two action ends of the elastic member 91 are respectively fixed to the frame 10 and the connecting rod 90. The connecting rod 90 can be inserted into the mounting hole from bottom to top in the vertical direction. The elastic member 91 makes the connecting rod 90 always have a tendency to move upward away from the frame 10 in the vertical direction. When the trolley needs to carry the carrier, a downward force is applied to the connecting rod 90 in the vertical direction, so that the connecting member slides downward. At this time, the elastic member 91 undergoes elastic deformation and begins to store energy. After aligning the connecting rod 90 with the mounting hole, the vertical downward force is removed, and the elastic member 91 recovers its deformation, so that the connecting rod 90 slides vertically upward, is inserted into the mounting hole, and remains in the plug-in state. When the connection state needs to be released, a vertical downward force is applied to the connecting rod 90 again, so that the connecting rod 90 withdraws from the mounting hole.

[0057] In order to keep the trolley stable and flexible with the carrier, the trolley provided by the present invention has two connecting rods 90, which are arranged at intervals on both sides of the frame 10 along the first horizontal direction. The trolley also includes a synchronization rod 92, which connects the two connecting rods 90 along the first horizontal direction. The connecting rod 90 includes a sliding portion 901, a plug-in portion 903 and a connecting portion 902. The sliding portion 901 is slidably connected to the frame 10. The carrier has two mounting holes along the first horizontal direction. The spacing between the two plug-in portions 903 is the same as the spacing between the two mounting holes. The connecting portion 902 connects the plug-in portion 903 and the sliding portion 901. With such a configuration, when the carrier carries the trolley, the pulling force of the carrier on the trolley acts on both sides of the trolley through the two connecting rods 90, so that the trolley can move smoothly. And the two connecting rods 90 can be controlled simultaneously by the synchronization rod 92.

[0058] Optionally, the wheels 20 provided at the bottom of the trolley are universal wheels. Such arrangement makes the trolley more flexible when turning.

[0059] In addition, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
