Referring to fig. 1-7, a quick release locking mechanism 10 may be used to connect a stripper member 20 to a fitting member 320. The quick release locking mechanism 10 includes a cam 112, a locking block 122, and a trigger block 132. The cam 112 is disposed on the detachable member 20, and the cam 112 includes a cam body 1122, a protruding portion 1124 extending from an outer side surface 1122a of the cam body 1122, and a trigger portion 1126 extending from a bottom surface 1122b of the cam body 1122. The lock block 122 includes a contact portion 1222 and a locking portion 1224, the contact portion 1222 corresponds to the protrusion 1124, the locking portion 1224 is configured to cooperate with the locking surface 322 of the fitting 320, when the cam 112 rotates in the first direction, the protrusion 1124 drives the lock block 122 to move forward until the locking portion 1224 abuts against the locking surface 322, so that the dismounting member 20 is connected with the fitting 320. When the cam 112 is rotated in the second direction, the locking block 122 moves in a reverse direction and drives the locking portion 1224 away from the locking surface 322, thereby disengaging the release member 20 from the fitting 320. The trigger block 132 includes a trigger projection 1322, the trigger block 132 is movable relative to the cam 112, and when the trigger block 132 is in the first position, the trigger projection 1322 interferes with the trigger part 1126 (the cam 112 is restrained); when the trigger block 132 is in the second position, the trigger projection 1322 releases the trigger 1126 (the cam 112 can rotate normally). In the present embodiment, the forward direction refers to a direction away from the cam 112, and the reverse direction refers to a direction toward the cam 112. It will be appreciated that in another embodiment, forward may refer to a direction toward the cam 112 and reverse may refer to a direction away from the cam 112. For example, when the cam 112 rotates in the first direction, the locking block 122 can move forward and drive the locking portion 1224 to disengage from the locking surface 322, and when the cam 112 rotates in the second direction, the protrusion 1124 can push the contact portion 1222 to drive the locking block 122 to move backward until the locking portion 1224 interferes with the locking surface 322.

The quick release locking mechanism 10 of the embodiment of the invention is matched with the cam 112, the locking block 122 and the trigger block 132 to quickly mount or dismount the quick release locking mechanism 10 on the assembly member 320, so that the dismounting efficiency can be improved. The quick release locking mechanism 10 is reliable, has large locking force and is easy to operate.

With continued reference to fig. 1, the first direction may be a counterclockwise direction, and the second direction may be a clockwise direction (the quick release locking mechanism 10 of fig. 1 is in an unlocked state, in which the cam 112 can rotate in the first direction, and the quick release locking mechanism of fig. 10 is in a locked state, in which the cam 112 can rotate in the second direction). In one embodiment, the cam 112 may be rotated 120 degrees in a first direction to cause the locking portion 1224 to interfere with the locking surface 322 and the cam 112 may be rotated 120 degrees in a second direction to cause the locking portion 1224 to disengage from the locking surface 322.

The detachable member 20 may be a handle 20, and the assembly member 320 may be disposed on the head 300 (see fig. 15), so that the handle 20 may be quickly connected to or disconnected from the head 300, so that the head 300 may be conveniently switched between a ground application scene and an aerial application scene.

Referring to fig. 8, the distance (hereinafter, simply referred to as distance) between the outer side surface 1124a of the protrusion 1124 and the central axis 1122c of the cam body 1122 is gradually changed, so that when the cam 112 rotates along the first direction, the distance of the protrusion 1124 corresponding to the contact 1222 is gradually increased, and the protrusion 1124 pushes the contact 1222 to move the locking block 122 in the forward direction, wherein the forward movement may be a movement in a direction away from the cam 112, and correspondingly, the reverse movement may be a movement in a direction approaching the cam 112.

In some embodiments, when the cam 112 moves in the first direction, the distance of the protrusion 1124 corresponding to the contact portion 1222 is gradually decreased, so that the protrusion 1124 releases the contact portion 1222, so that the lock block 122 moves in a forward direction, wherein the forward direction may be a direction approaching the cam 112, and correspondingly, the reverse direction may be a direction moving away from the cam 112.

The two triggering protrusions 1322 include two triggering portions 1126, and the two triggering portions 1126 include interference surfaces 1126a, the interference surfaces 1126a having a rectangular shape, for example, such that when the triggering block 132 is in the first position, the two triggering protrusions 1322 interfere with the interference surfaces 1126a to restrict the cam 112 from rotating, and when the triggering block 132 is in the second position, the two triggering protrusions 1322 release the interference surfaces 1126a, so that the cam 112 can normally rotate. Of course, the abutting surface 1126a may have other shapes such as a triangle and an ellipse.

Referring to fig. 9, the number of the locking portions 1224 is two, and the two locking portions 1224 cooperating with the locking surface 322 can provide a greater locking force. Of course, the number of the locking parts 1224 may be one or more, and is not particularly limited herein.

Referring to fig. 2, fig. 3 and fig. 6 again, the quick release locking mechanism 10 further includes a base 14, a bolt 114 and a handle 116, the base 14 defines an accommodating groove 142, a bottom 1421 of the accommodating groove 142 defines a mounting hole 1422, the cam 112 is accommodated in the accommodating groove 142 and corresponds to the mounting hole 1422, the handle 116 and the cam 112 are both sleeved on the bolt 114 and can rotate around the bolt 114, the handle 116 is fixedly connected to the cam 112, a first end 1142 of the bolt 114 extends into the mounting hole 1422 and is fixedly connected to the mounting hole 1422, the handle 116 is sleeved on a second end 1144 of the bolt 114, and the first end 1142 is opposite to the second end 1144. The cam 112 is positioned between the first end 1142 and the second end 1144.

The user can rotate the cam 112 by the handle 116, and in addition, the handle 116 and the cam 112 are fixed relatively and rotate together around the bolt 114, so that the handle 116 and the cam 112 can be prevented from deviating from the positions when rotating. The bolt 114 is fixed in the mounting hole 1422, and when the handle 116 and the cam 112 rotate, the bolt 114 is stationary relative to the base 14, i.e., the bolt 114 does not rotate, thereby preventing the bolt 114 from wearing in the mounting hole 1422.

The handle 116 and the cam 112 may be directly fixedly connected by a screw connection, a snap connection, an integral molding, or the like, and is not particularly limited herein. For example: the handle 116 is provided with internal threads, the cam body 1122 is provided with external threads, and the cam body 1122 extends into the handle 116 and is screwed through the threads; alternatively, the handle 116 may be externally threaded, the cam body 1122 may be internally threaded, and the handle 116 may extend into the cam body 1122 and be threadably tightened. Referring to fig. 8 again, in an embodiment, the cam body 1122 is formed with a locking groove 1122d, the handle 116 includes a connecting portion 1162, an inner wall of the connecting portion 1162 is formed with a locking protrusion (not shown), and the locking groove 1122d corresponds to the locking protrusion, and the number of the locking protrusions may be one or more. When the handle 116 and the cam 112 are fixedly connected, the engaging protrusion engages with the engaging groove 1122d, so that the handle 116 and the cam 112 are fixed relative to each other and can rotate together around the bolt 114. It is understood that the connection form of the cam body 1122 and the connection portion 1162 of the handle 116 is not limited thereto, for example, a snap projection may be formed on the cam body 1122 and a snap groove may be correspondingly formed on the connection portion 1162, or the cam body 1122 and the connection portion 1162 may be in an interference fit, which is not limited herein. In other embodiments, the cam body 1122 may be fixedly connected to the connecting portion 1162 of the handle 116 by using an adhesive, or may be integrally formed with the connecting portion 1162.

In some embodiments, the handle 116 and the cam 112 may also be indirectly fixedly connected. Specifically, the handle 116 is fixedly attached to the second end 1144 of the bolt 114, and the cam 112 is fixedly attached between the first end 1142 and the second end 1144, i.e., the handle 116 and the cam 112 are fixedly attached by the bolt 114. At this point, the first end 1142 of the bolt 114 extends into the mounting hole 1422 and is rotatably engaged with the mounting hole 1422. When the cam 112 is rotated, the bolt 114 and the handle 116 are correspondingly rotated.

Referring to fig. 3 and 6 again, the quick release locking mechanism 10 further includes an elastic element 118, the trigger portion 1126 and the cam body 1122 together form an accommodating groove 1128, the trigger portion 1126 is carried on the bottom surface 1421 of the accommodating groove 142, the elastic element 118 is accommodated in the accommodating groove 1128, one end 1182 of the elastic element 118 is fixed to the base 14, and the other end 1184 of the elastic element 118 is combined with the cam 112 to provide a pre-tightening rotating force to the cam 112 (the cam 112 of the quick release locking mechanism 10 in the unlocked state in fig. 1 has a pre-tightening rotating force, and when the trigger protrusion 1322 releases the trigger portion 1126, the pre-tightening rotating force causes the cam 112 to rotate in the first direction). The elastic member 118 may be a torsion spring, a spring, or the like, and may also be an element made of an elastic material.

The base 14 may be formed with a fixing hole 143, one end 1182 of the elastic element 118 may be inserted into the fixing hole 143 to be fixed on the base 14, the number of the fixing holes 143 may be one or more, and the plurality of fixing holes 143 is beneficial for a user to select a suitable fixing hole 143 to fix the elastic element 118 according to a requirement so as to be able to provide pre-tightening rotating forces of different sizes. In addition, the trigger 1126 and the cam body 1122 together form an accommodating groove 1128 for accommodating the elastic element 118, so that the trigger 1126 can be directly carried on the bottom surface 1421 of the accommodating groove 142, the heights of the elastic element 118 and the cam 112 are reduced, and the size of the quick release locking mechanism 10 is reduced.

In some embodiments, the triggering portion 1126 extends from the outer side 1122a of the cam body 1122 (no accommodating groove 1128 is formed between the triggering portion 1126 and the cam body 1122), one end 1182 of the elastic element 118 is fixed to the base 14, and the other end 1184 of the elastic element 118 is combined with the bottom surface of the triggering portion 1126 to provide a pre-tightening rotational force to the cam 112. At this time, the trigger 1126 does not directly contact the bottom 1421 of the storage tub 142.

Referring to fig. 10, fig. 11 and fig. 12, the quick release locking mechanism 10 further includes a guiding post 15 extending from the bottom 1424 of the receiving groove 142, the guiding post 15 is provided with a guiding hole 152 corresponding to the mounting hole 1422, the first end 1142 extends into the guiding hole 152 and the mounting hole 1422, and the elastic element 118 is sleeved on the guiding post 15.

The first end 1142 of the bolt 114 extends into the mounting hole 1422 through the guiding hole 152, the guiding hole 152 can prevent the first end 1142 of the bolt 114 from being separated from the mounting hole 1422, and the elastic element 118 can be sleeved on the guiding post 15, and the guiding post 15 can prevent the elastic element 118 from inclining or deviating from the position.

Referring to fig. 3, 13 and 14, the quick release locking mechanism 10 further includes a cover plate 16, the cover plate 16 is combined with the base 14 to form an accommodating space 17, the cam 112, the elastic element 118 and the locking block 122 are all accommodated in the accommodating space 17, the bolt 114 penetrates through the cover plate 16, and the handle 116 is located outside the accommodating space 17.

The receiving space 17 formed by the cover 16 and the base 14 can protect the cam 112, the elastic element 118, and the locking block 122 received therein, and reduce or prevent the cam 112, the elastic element 118, and the locking block 122 from being interfered by the outside (e.g., moisture, dust, etc.). The handle 116 is located outside the receiving space 17 to facilitate the user to rotate the cam 112 by the handle 116.

The cover plate 16 may have through bolt holes 161 formed therein, and the bolts 114 may pass through the bolt holes 161. The cover plate 16 may further have a threaded hole 162, the base 14 may have a through hole 148, a screw may be inserted through the through hole 148 to connect with the threaded hole 162, and the cover plate 16 may be mounted on the base 14 by screwing the internal thread of the threaded hole 162 with the external thread of the screw. The screw is inserted into the base 14 after being installed, so as to prevent the screw from interfering with the assembly member 320 and affecting the installation of the locking structure 10.

Referring to fig. 3 again, the base 14 is provided with a through hole 144, the trigger block 132 further includes a trigger body 1324, the trigger body 1324 can be accommodated in the accommodating space 17 and corresponds to the through hole 144, the trigger body 1324 extends out of the accommodating space 17 from the through hole 144 or retracts into the accommodating space 17, and when the trigger body 1324 extends out of the accommodating space 17, the trigger block 132 is at the first position; when the trigger body 1324 is retracted into the receiving space 17, the trigger block 132 is in the second position.

The trigger body 1324 extends out of the receiving space 17 or retracts into the receiving space 17 through the through hole 144 (part of the structure of the trigger body 1324 is in the through hole 144, the through hole 144 can be regarded as a part of the receiving space 17), so that the trigger block 132 moves relative to the cam 112. When the trigger body 1324 extends out of the accommodating space 17, the trigger block 132 is in the first position, and the trigger projection 1322 abuts against the trigger part 1126; when trigger body 1324 is retracted into receptacle 17, trigger block 132 is in the second position, at which time trigger projection 1322 releases trigger 1126.

Referring to fig. 2 and fig. 3, the quick release locking mechanism 10 further includes a trigger elastic member 134, one end 1342 of the trigger elastic member 134 is connected to the trigger body 1324, and the other end 1344 of the trigger elastic member 134 abuts against the inner surface 163 of the cover plate 16.

The inner surface 163 of the cover 16 may be formed with a receiving hole 164, and the other end 1344 of the trigger elastic member 134 is abutted against the receiving hole 164. In this way, the trigger spring 134 is prevented from sliding on the cover plate 16.

When the triggering elastic member 134 does not receive the external force, the triggering elastic member 134 extends the triggering body 1324 out of the accommodating space 17, when the triggering elastic member 134 receives the external force, the triggering body 1324 retracts into the accommodating space 17, because the cover plate 16 is fixed, the triggering elastic member 134 is compressed at the moment, and after the external force is cancelled, the triggering elastic member 134 restores to the original state, so that the triggering body 1324 extends out of the accommodating space 17 again. The triggering elastic member 134 may be an elastic member such as a spring, rubber, etc., and is not particularly limited herein.

Referring to fig. 2, 3 and 9, the base 14 is provided with a through sliding groove 146, the locking block 122 includes a locking body 1226, the contact portion 1222 extends from a side surface of the locking body 1226 and penetrates the trigger block 132, the locking portion 1224 extends from a bottom surface of the locking body 1226, the locking body 1226 is located in the accommodating space 17, and the locking block 122 extends out of the base 14 from the sliding groove 146 and can move along the sliding groove 146.

Referring to fig. 7, a gap 1324a may be formed at a middle position of the trigger body 1324, and the contact portion 1222 may pass through the gap 1324a to correspond to the contact portion 1222, so that the trigger body 1324 can prevent the locking block 122 from deviating from the position when moving.

Referring to fig. 2 and 9, the locking portion 1224 is formed with a wedge-shaped notch 1227 to form an inclined clamping surface 1228, and when the locking portion 1224 abuts against the locking surface 322, the clamping surface 1228 forms a line contact with the locking surface 322.
