[0035] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] In this application, the first direction is Figure 5 The X direction in the middle, the second direction is Figure 5 The Z-direction in the middle.

[0037] like Figures 1 to 5As shown, an embodiment of the present invention provides a hooking mechanism 1, including a hooking component 11 and a support plate 12; the hooking component 11 includes a rotary drive 111, a lever 112, a connecting shaft 113, a bearing seat 110, a bearing assembly 114, and a first fastener 115; the bearing seat 110 is mounted on the support plate 12, the bearing assembly 114 is mounted on the bearing seat 110, and the rotary drive 111 is mounted on the support plate 12;

[0038] The lever 112 is provided with a first clamping arm 1121 and a second clamping arm 1122 spaced apart. A clamping groove 1123 is provided between the first clamping arm 1121 and the second clamping arm 1122. The first clamping arm 1121 is provided with a first fastening hole 1125 communicating with the clamping groove 1123. The second clamping arm 1122 is provided with a second fastening hole 1126 communicating with the clamping groove 1123.

[0039] One end of the connecting shaft 113 is connected to the output end of the rotary drive 111, and the other end of the connecting shaft 113 passes through the inner hole of the bearing assembly 114 and is inserted into the clamping groove 1123; the first fastener 115 is inserted into the first fastening hole 1125 and the second fastening hole 1126, and is used to adjust the distance between the first clamping arm 1121 and the second clamping arm 1122.

[0040] The first fastening hole 1125 and the second fastening hole 1126 include, but are not limited to, threaded holes; the first fastener 115 includes, but is not limited to, screws and bolts; the rotary drive component 111 includes, but is not limited to, a motor; the bearing assembly 114 includes, but is not limited to, an oilless bushing and a sliding bearing; the bearing seat 100 is provided with a bearing through hole for mounting the bearing assembly 114; and the connecting shaft 113 is rotatably mounted on the bearing seat 100 via the bearing assembly 114.

[0041] Specifically, the rotary drive 111 can drive the lever 112 to rotate via the connecting shaft 113, so that the lever 112 is in a vertical or horizontal state; when the lever 112 is in a vertical state, during the forward or backward movement of the hooking mechanism 1, the lever 112 can avoid the item to be hooked (such as a courier package); when the lever 112 is in a horizontal state, the lever 112 can push or pull the item to be hooked.

[0042] In this invention, the lever 112 is provided with a first clamping arm 1121 and a second clamping arm 1122 spaced apart. A clamping groove 1123 is provided between the first clamping arm 1121 and the second clamping arm 1122. The first clamping arm 1121 is provided with a first fastening hole 1125 communicating with the clamping groove 1123, and the second clamping arm 1122 is provided with a second fastening hole 1126 communicating with the clamping groove 1123. One end of the connecting shaft 113 is connected to the output end of the rotary drive 111, and the other end of the connecting shaft 113 passes through the inner hole of the bearing assembly 114 and is inserted into the clamping groove 1123. A first fastener 115 is inserted into the first fastening hole 1125 and the second fastener. In hole 1126; the first fastener 115 can adjust the distance between the first clamping arm 1121 and the second clamping arm 1122. When the distance between the first clamping arm 1121 and the second clamping arm 1122 is shortened, the first clamping arm 1121 and the second clamping arm 1122 can clamp the connecting shaft 113, thereby completing the connection between the connecting shaft 113 and the lever 112; when the distance between the first clamping arm 1121 and the second clamping arm 1122 is increased, the first clamping arm 1121 and the second clamping arm 1122 can loosen the connecting shaft 113, thereby completing the disassembly between the connecting shaft 113 and the lever 112. In this embodiment, the hooking mechanism 1 has a simple structure and is easy to assemble and disassemble.

[0043] In one embodiment, such as Figure 4 and Figure 5 As shown, the lever 112 is provided with a first through hole 1124 that passes through the first clamping arm 1121 and the second clamping arm 1122 along a first direction, and the first through hole 1124 communicates with the clamping groove 1123;

[0044] Both the first fastening hole 1125 and the second fastening hole 1126 extend along the second direction; the first direction is perpendicular to the second direction;

[0045] One end of the connecting shaft 113 away from the rotary drive 111 is inserted into the clamping groove 1123 and the first through hole 1124.

[0046] The first through hole 1124 includes a first arc-shaped hole provided on the first clamping arm 1121 and a second arc-shaped hole provided on the second clamping arm 1122. The first fastening hole 1125 is adapted to the first fastener 115, and the second fastening hole 1126 is also adapted to the first fastener 115.

[0047] In this embodiment, the first fastener 115 can adjust the distance between the first clamping arm 1121 and the second clamping arm 1122 so that the connecting shaft 113 is fixedly inserted into the first through hole 1124 and the clamping groove 1123, and ensures the stability of the connection between the connecting shaft 113 and the lever 112.

[0048] In one embodiment, such as Figure 3 and Figure 4 As shown, the bearing assembly 114 includes a first bearing 1141 with a first flange 11411 and a second bearing 1142 with a second flange 11421; the bearing housing 110 is provided with a bearing hole, and the first bearing 1141 and the second bearing 1142 are both installed in the bearing hole, and the first flange 11411 and the second flange 11421 respectively abut against the opposite sides of the bearing housing.

[0049] The first bearing 1141 can be inserted into the bearing hole from the inside, and the second bearing 1142 can be inserted into the bearing hole from the outside; the side of the first bearing 1141 away from the second bearing 1142 abuts against the lever 112.

[0050] In this embodiment, when the lever 112 is subjected to an axial force along the connecting shaft 113, the lever 112 can transmit the force to the bearing seat 110 through the first flange 11411, so that the connecting shaft 113 will not be subjected to axial force, thus avoiding the accident of damage to the rotary drive component 111 due to axial force and extending the service life of the rotary drive component 111.

[0051] In one embodiment, such as Figure 2 and Figure 3 As shown, the hooking component 11 further includes a limiting component 116, which includes a first limiting seat 1161, a second limiting seat 1162, and a limiting block 1163 with a limiting protrusion 11631; the limiting block 1163 is mounted on the connecting shaft 113, and the first limiting seat 1161 and the second limiting seat 1162 are both mounted on the support plate 12;

[0052] The limiting protrusion 11631 is disposed opposite to the first limiting seat 1161 and the second limiting seat 1162, and the limiting component 116 is used to limit the rotation angle of the connecting shaft 113.

[0053] The first limiting seat 1161 extends vertically, and the second limiting seat 1162 extends horizontally.

[0054] Specifically, during the rotation of the connecting shaft 113 and the limiting block 1163 by the rotary drive 111, when the limiting protrusion 11631 of the limiting block 1163 abuts against the first limiting seat 1161, the lever 112 is in a horizontal state; when the limiting protrusion 11631 of the limiting block 1163 abuts against the second limiting seat 1162, the lever 112 is in a vertical state. In this embodiment, the limiting component 116 can restrict the rotation of the lever 112 between the horizontal and vertical states, ensuring the stability of the rotation of the hooking mechanism 1.

[0055] In one embodiment, such as Figures 2 to 4 As shown, the limiting block 1163 is provided with a clamping groove 11632 and a third fastening hole penetrating the clamping groove 11632;

[0056] The connecting shaft 113 is provided with a first cut surface 1131, and the first cut surface 1131 is provided with a fourth fastening hole 1132;

[0057] The hooking component 11 further includes a second fastener 117. The limiting block 1163 clamps the connecting shaft 113 through the clamping groove 11632. The first cut surface 1131 fits against the inner wall of the clamping groove 11632. The second fastener 117 is inserted into the third fastening hole and the fourth fastening hole 1132.

[0058] The second fastener 117 includes, but is not limited to, bolts, screws, etc., and the third fastening hole and the fourth fastening hole 1132 include, but are not limited to, threaded holes; the third fastening hole is provided on the two opposite inner walls of the clamping groove 11632, and the first cut surface 1131 is provided on the opposite sides of the connecting shaft 113. There are two second fasteners 117.

[0059] In this embodiment, the connecting shaft 113 passes through the clamping groove 11632 of the clamping slot, the first cut surface 1131 is in contact with the inner wall of the clamping groove 11632, and the second fastener 117 is inserted into the third fastening hole and the fourth fastening hole 1132. Thus, the limiting block 1163 is mounted on the connecting shaft 113 by the second fastener 117 inserted into the third fastening hole and the fourth fastening hole 1132, ensuring the stability of the limiting block 1163 mounted on the connecting shaft 113. In addition, since the first cut surface 1131 is in contact with the inner wall of the clamping groove 11632, slippage between the limiting block 1163 and the connecting shaft 113 is less likely to occur during rotation.

[0060] In one embodiment, such as Figure 2 and Figure 3As shown, the hooking component 11 also includes a sensing plate 118 and a sensor 119. The sensing plate 118 is mounted on the connecting shaft 113, and the sensor 119 is mounted on the support plate 12. The sensor 119 is used to detect the rotation angle of the connecting shaft 113 through the sensing plate 118.

[0061] The sensing sheet 118 includes, but is not limited to, a magnet, and the sensor 119 includes, but is not limited to, a magnetic sensor; further, the sensing sheet 118 is mounted on the limiting protrusion 11631.

[0062] Specifically, during the process of the rotary drive 111 driving the connecting shaft 113, the sensor 119 can detect the rotation angle of the connecting shaft 113 in real time through the sensing plate 118; when it is detected that the limiting protrusion 11631 is about to contact the first limiting seat 1161 or the second limiting seat 1162, the rotary drive 111 can be de-energized or decelerated, thereby reducing the impact force between the limiting protrusion 11631 and the first limiting seat 1161 and the second limiting seat 1162.

[0063] In one embodiment, such as Figure 1 As shown, the hooking mechanism 1 includes two hooking components 11, which are installed at intervals on the support plate 12.

[0064] Two of the hooking components 11 are mounted on the support plate 12 at intervals along a first direction.

[0065] In this embodiment, the front hooking component 11 can pull the object to be hooked, and the rear hooking component 11 can push the object to be hooked forward; when the user does not place the object to be hooked in place, the rear hooking component 11 can push the object to be hooked forward to the hooking component 11, thereby facilitating the rear hooking component 11 to pull the object to be hooked backward.

[0066] like Figure 6 As shown, another embodiment of the present invention also provides a connecting device, including a support base 2, a moving drive (not shown in the figure) and the hooking mechanism 1 described above. The support plate 12 is slidably mounted on the support base 2, and the moving drive is mounted on the support base 2 and connected to the support plate 12. The moving drive is used to drive the hooking mechanism 1 to move along a first direction.

[0067] The moving drive components include, but are not limited to, pneumatic cylinders, hydraulic cylinders, belt mechanisms, and lead screw and nut mechanisms. The support plate 12 can be slidably mounted on the support base 2 via the guide rail 4 slider assembly and the guide rod sleeve assembly.

[0068] Specifically, the rotary drive 111 drives the lever 112 to be in a vertical state, and the moving drive drives the hooking mechanism 1 to move to the rear of the object to be hooked; the rotary drive 111 drives the lever 112 to be in a horizontal state, and the moving drive drives the hooking mechanism 1 to move backward, so that the lever 112 can pull the object to be hooked backward.

[0069] In this invention, the connecting device has a simple structure and low manufacturing cost.

[0070] In one embodiment, such as Figure 1 and Figure 6 As shown, the connecting device also includes a guide rail 4 and a plurality of first support wheels 5 that are spaced apart on the support plate 12 along a first direction, and the guide rail 4 is mounted on the support base 2;

[0071] The first arc-shaped guide portion 41 extends along the first direction on the guide rail 4, and each of the first support wheels 5 is provided with a first rolling groove, and the first arc-shaped guide portion 41 is slidably inserted into the first rolling groove.

[0072] The number of the first support wheels 5 can be set according to actual needs, and the cross-section of the first arc-shaped guide part 41 can be semi-circular arc; all the first support wheels 5 are located above the guide rail 4.

[0073] Specifically, during the movement of the hooking mechanism 1 along the first direction driven by the moving drive component, the first support wheel 5 rolls on the first arc-shaped guide portion 41, thereby allowing the guide rail 4 to support the hooking mechanism 1 through the first arc-shaped guide portion 41 and the first support wheel 5. The rolling friction between the guide rail 4 and the first support wheel 5 results in low friction, ensuring the stability of the hooking assembly's movement.

[0074] In one embodiment, such as Figure 1 As shown, the guide rail 4 has a second arc-shaped guide portion 42 on the side opposite to the first arc-shaped guide portion 41;

[0075] The connecting device also includes a plurality of second support wheels 6 that are spaced apart on the support plate 12 along a first direction, and each second support wheel 6 is provided with a second rolling groove.

[0076] The second arc-shaped guide portion 42 is slidably inserted into the second rolling groove.

[0077] The number of the second support wheels 6 can be set according to actual needs, and the cross-section of the second arc-shaped guide part 42 can be semi-circular arc; all the second support wheels 6 are located below the guide rail 4.

[0078] Specifically, during the process of the moving drive component driving the hooking mechanism 1 to move along the first direction, the first arc-shaped guide portion 41 moves on the second support wheel 6, thereby allowing the second support wheel 6 to support the guide rail 4. The guide rail 4 and the second support wheel 6 experience rolling friction, resulting in relatively low frictional force between them, further ensuring the stability of the hooking assembly's movement.

[0079] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
