Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock technology, and in particular to a lock and a logistics container. Background Technology
[0002] Logistics containers are indispensable tools in modern logistics transportation and warehousing, used for loading, protecting, and transporting various goods. The doors of logistics containers are usually equipped with locks to prevent goods from falling out once the doors are locked. However, current technology makes these locks inconvenient to operate, requiring users considerable time to unlock and lock them. This can lead to longer loading and unloading times, thus impacting logistics turnover efficiency. Utility Model Content
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a lock that is highly convenient to operate.
[0004] This utility model also provides a logistics container including the above-mentioned lock.
[0005] A lock according to a first aspect of the present invention includes: a mounting base; a locking pin rotatably connected to the mounting base, the locking pin including a locking portion, the locking pin being rotatable relative to the mounting base to switch between a first angle and a second angle; and a latch having a notch; when the lock is in a locked state, the locking pin is at the first angle, the locking portion is located within the notch, the inner wall of the notch is capable of preventing the locking portion from moving along a reference plane and leaving the notch, thereby preventing the latch from separating from the locking pin, the reference plane being perpendicular to the rotation axis of the locking pin; when the lock is in an unlocked state, the locking pin is at the second angle, the locking portion is located outside the notch, and the latch is capable of moving relative to the mounting base along the reference plane to allow the locking portion to enter the notch.
[0006] The lock according to the first aspect of the present invention has at least the following beneficial effects:
[0007] In existing lock technology, the locking pin is inserted into the latch along its own axis. Therefore, during locking and unlocking, the user not only needs to rotate the locking pin, but also needs to drive the locking pin to move significantly along its axis.
[0008] As for the lock of this invention, since the latch moves relative to the locking pin along a reference plane (the reference plane is perpendicular to the axis of the locking pin), the locking pin does not need to move significantly along its own axis during unlocking and locking. This helps to shorten the distance the user's hand needs to move, thereby improving the ease of operation of the lock. In addition, the lock of this invention does not require complex electronic components, and the lock structure is simple and the cost is low.
[0009] According to some embodiments of the present invention, the outer peripheral surface of the locking part includes two opposing first surfaces and two opposing second surfaces, the distance between the two first surfaces is the unlocking distance, and the distance between the two second surfaces is the locking distance; the notch includes a receiving area and a transition area distributed along a first direction, the width of the transition area in the second direction is a first distance, the width of the receiving area in the second direction is a second distance, and any two of the first direction, the second direction, and the axial direction of the locking pin are perpendicular to each other; wherein, the second distance is greater than the locking distance, the locking distance is greater than the first distance, and the first distance is greater than the unlocking distance; when the lock is in the locked state, the two second surfaces are distributed along the second direction; when the locking pin is at the second angle and the locking part is located within the receiving area, the two first surfaces are distributed along the second direction.
[0010] According to some embodiments of the present invention, the first surface is a plane, the two first surfaces are parallel to each other, and the first surface is parallel to the rotation axis; and / or, the second surface is an arc surface, and the second surface surrounds the rotation axis.
[0011] According to some embodiments of the present invention, the transition zone includes two transition surfaces spaced apart in the second direction, the transition surfaces being planes, the two transition surfaces being parallel to each other, and the rotation axis being parallel to the transition surfaces; and / or, the inner wall surface of the receiving area is an arc surface.
[0012] According to some embodiments of the present invention, the mounting base has a first limiting hole, and the locking pin further includes a limiting portion. The limiting portion and the locking portion are fixed relative to each other and are spaced apart along the axial direction of the locking pin. When the lock is in the locked state, the limiting portion is located inside the first limiting hole, and the inner wall surface of the first limiting hole can contact the outer peripheral surface of the limiting portion to prevent the locking pin from rotating. When the lock is in the unlocked state, the limiting portion is located outside the first limiting hole.
[0013] According to some embodiments of the present invention, the cross-section of the limiting part and the first limiting hole are both waist-shaped.
[0014] According to some embodiments of the present invention, the lock further includes an elastic element, and the mounting base and the locking pin are both connected to the elastic element. The elastic force of the elastic element is used to drive the locking pin to move along the axial direction so that the limiting part enters the first limiting hole.
[0015] According to some embodiments of the present invention, the mounting base has a second limiting hole. When the lock is in the locked state, a portion of the locking part is located inside the second limiting hole, and the inner wall surface of the second limiting hole can contact the outer peripheral surface of the locking part to prevent the lock pin from rotating. When the lock is in the unlocked state, the locking part is located outside the second limiting hole.
[0016] According to some embodiments of the present invention, the cross-section of the locking part and the second limiting hole are both oblong.
[0017] A logistics container according to a second aspect embodiment of the present invention includes: a lock as described in the first aspect embodiment; a body; a door, the door being movably connected to the body, the door and the body jointly defining a storage space, one of the door and the body being connected to the mounting base, and the other being connected to the latch.
[0018] The logistics container according to the second aspect of the present invention has at least the following beneficial effects: due to the high ease of operation of the lock, the efficiency of loading and unloading goods using the logistics container is high.
[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0039] Figure 1 A logistics container 101 according to an embodiment of the present invention is shown, such as Figure 1 As shown, the logistics container 101 includes a main body 102, a door 103, and a lock 104. The main body 102 and the door 103 are rotatably connected by a hinge 106, and the door 103 can be rotated forward to be opened (e.g., Figure 2 (As shown). The main body 102 and the door 103 together define a storage space 105, which can accommodate items such as logistics packages. In some other embodiments not shown, the door 103 can also be a sliding door (e.g., the door 103 can slide in the left and right direction), as long as the door 103 is movably connected to the main body 102 and the door 103 can be opened and closed.
[0040] like Figure 3 and Figure 4As shown, the lock 104 includes a locking pin 107, a latch 108, and a mounting base 109. The mounting base 109 is connected to the body 102, and the latch 108 is connected to the door 103. The latch 108 has a notch 111. When the door 103 is closed, a portion of the latch 108 is located inside the mounting base 109; when the door 103 is opened, the latch 108 separates from the mounting base 109. In some other embodiments not shown, the mounting base 109 may be connected to the door 103, and the latch 108 may be connected to the body 102. The locking pin 107 includes a locking portion 113. The locking pin 107 is rotatably connected to the mounting base 109 and is rotatable relative to the mounting base 109, thereby switching the locking pin 107 between a first angle and a second angle. The axis of rotation of the locking pin 107 may be its own central axis. Figure 3 and Figure 6 In the middle, locking pin 107 is at the first angle; in Figure 4 , Figure 7 and Figure 8 In the first angle, the locking pin 107 is at the second angle. The angle difference between the first angle and the second angle is 90°. In other embodiments not shown, the angle difference between the first angle and the second angle may also be an acute angle or an obtuse angle.
[0041] The lock 104 has three states: locked, intermediate, and unlocked. When the lock 104 is in the locked state, the door 103 is closed and locked. When the lock 104 is in the unlocked state, the door 103 is open and unlocked. When the lock 104 is in the intermediate state, the door 103 is closed but not locked.
[0042] When lock 104 is in the locked state, such as Figure 6 As shown, the locking pin 107 is at a first angle, and the locking part 113 is located within the notch 111. The inner wall of the notch 111 can prevent the locking part 113 from moving along the reference plane and thus leaving the notch 111, thereby preventing the locking pin 107 from separating from the latch 108. The reference plane is perpendicular to the rotation axis of the locking pin 107. The reference plane is not shown in the figures. In this embodiment, the rotation axis is a vertical line, and the reference plane is a horizontal plane. Furthermore, when the lock 104 is in the locked state, the locking pin 107 cannot move backward along the reference plane (horizontal plane) and leave the notch 111.
[0043] When lock 104 is in the intermediate state, such as Figure 7 As shown, the locking pin 107 is at the second angle, and the locking part 113 is located inside the notch 111. However, the wall of the notch 111 does not obstruct the movement of the locking part 113, and the locking part 113 can move along the reference plane to move away from the notch 111. At this time, the user can pull the door 103 to rotate the door 103 forward, thereby causing the locking part 113 to move away from the notch 111.
[0044] When lock 104 is in the unlocked state, such as Figure 8 As shown, the locking pin 107 is at the second angle, the locking part 113 is outside the notch 111, and the door 103 can rotate freely so that the user can rotate the door 103 to the desired angle. At this time, the latch 108 can move relative to the mounting base 109 along the reference plane (moving forward along the reference plane) so that the locking part 113 enters the notch 111. The latch 108 can move along... Figure 8 The arc 125 shown moves, and the center of the arc 125 is located on the axis of the hinge 106.
[0045] The following describes how to use the lock 104. When the user needs to unlock, they can rotate the locking pin 107 to the second angle. When the user needs to lock, they can first move the latch 108 relative to the locking pin 107 along a reference plane, causing the locking pin 107 to engage with the notch 111 of the latch 108; this can be done by closing the door 103. Then, the user rotates the locking pin 107 to the first angle. The lock 104 is highly convenient to operate, facilitating both locking and unlocking.
[0046] To explain why the lock 104 of this utility model has high ease of operation, the following describes locks in the prior art. Figure 9 A portion of a prior art logistics container 101 is shown, in which a locking pin 107 is also connected to a handle 126, which can engage with a limiting structure 134. For Figure 9 The lock shown has the following unlocking process in sequence: (a) lifting the handle 126 upwards until the handle 126 disengages from the limiting structure 134; (b) pulling the handle 126 to the right until the locking pin 107 disengages from the hole (not shown) of the latch 108. For Figure 9 The locking process of the lock shown includes the following steps in sequence: (c) moving the latch 108 relative to the locking pin 107 along the reference plane until the hole on the latch 108 is aligned with the locking pin 107. This specific operation can be closing the door 103; (d) pulling the handle 126 to the left until the locking pin 107 is inserted into the latch 108.
[0047] Therefore, in the existing lock 104, the locking pin 107 is inserted into the latch 108 along its own axis. Thus, during locking and unlocking, the user not only needs to rotate the locking pin 107, but also needs to drive the locking pin 107 to move significantly along its axis.
[0048] Regarding the lock 104 of this invention, since the latch 108 moves relative to the locking pin 107 along a reference plane, the locking pin 107 does not need to move significantly along its own axis during unlocking and locking. This helps to shorten the distance the user's hand travels, thereby improving the ease of operation of the lock 104. Furthermore, the lock 104 of this invention does not require a handle 126 connected to the outer periphery of the locking pin 107, thus its size is smaller. In addition, the lock 104 of this invention does not require complex electronic components, resulting in a simple structure and low cost.
[0049] The specific structure of the lock 104 of this utility model will be described below.
[0050] like Figure 5 As shown, the outer peripheral surface of the locking part 113 includes two opposing first surfaces 120 and two opposing second surfaces 119. For example, the two first surfaces 120 may be distributed along the front-back direction, and the two second surfaces 119 may be distributed along the left-right direction. The first surfaces 120 and the second surfaces 119 are distributed around the rotation axis of the locking pin 107. The distance between the two first surfaces 120 is the unlocking distance L4, and the distance between the two second surfaces 119 is the locking distance L3. In this invention, the distance between the two surfaces refers to the maximum distance in the distribution direction of these two surfaces. For example, as... Figure 6 As shown, the second surface 119 is an arc surface, and the two second surfaces 119 are distributed along the front-back direction. The maximum distance between the two second surfaces 119 in the front-back direction is the locking distance L3.
[0051] like Figure 6 As shown, the notch 111 includes a receiving area 121 and a transition area 122 distributed along a first direction. The width of the transition area 122 in a second direction is a first distance L1, and the width of the receiving area 121 in the second direction is a second distance L2. Any two of the first direction, the second direction, and the axial direction of the locking pin 107 are perpendicular to each other. Figure 6 and Figure 7 In the diagram, the first direction is the front-to-back direction, and the second direction is the left-to-right direction. The four distances mentioned above satisfy the following condition: L2>L3>L1>L4.
[0052] like Figure 6 As shown, when the lock 104 is in the locked state, the locking pin 107 is located within the receiving area 121, and the two second surfaces 119 are distributed along the second direction. At this time, since L3>L1, the locking part 113 is blocked by the latch 108 when it moves backward relative to the latch 108, and the locking part 113 cannot disengage from the notch 111. Since L2>L3, the locking part 113 can rotate within the receiving area 121 so that the user can change the angle of the locking pin 107.
[0053] like Figure 7 As shown, when the locking pin 107 is at the second angle and the locking part 113 is located within the receiving area 121 (i.e., when the lock 104 is in the intermediate state), the two first surfaces 120 are distributed along the second direction. At this time, since L1>L4, the locking part 113 will not be blocked by the latch 108 when it moves backward relative to the latch 108, and the latch 108 can disengage from the notch 111 so that the user can further switch the lock 104 to the unlocked state.
[0054] like Figure 5 As shown, the first surface 120 can be a plane, the two first surfaces 120 are parallel to each other, and the first surface 120 is parallel to the rotation axis of the locking pin 107. The second surface 119 can be an arc surface, and the second surface 119 surrounds the rotation axis. In this configuration, the locking part 113 is waist-shaped, and the shape complexity and processing difficulty of the locking pin 107 are relatively low.
[0055] like Figure 6 As shown, the transition zone 122 includes two transition surfaces 124 spaced apart in the second direction. The transition surfaces 124 are planar, parallel to each other, and the axis of rotation is parallel to the transition surfaces 124. The inner wall of the receiving zone 121 is an arc surface. In this configuration, the shape of the notch 111 matches the waist-shaped locking part 113 to a high degree, and the shape complexity and processing difficulty of the notch 111 are relatively low.
[0056] It should be noted that, in order to satisfy the condition L2>L3>L1>L4, the shapes of the locking part 113 and the notch 111 are not limited to the shapes described above. For example, as Figure 12 As shown, in another embodiment, the cross-sectional shape of the locking part 113 can also be rectangular, that is, both the first surface 120 and the second surface 119 are planar. For example, as... Figure 13 As shown, in another embodiment, the cross-sectional shape of the receiving area 121 of the notch 111 is rectangular. The shapes of the locking part 113 and the notch 111 are not listed here.
[0057] During the transportation of the logistics container 101, it will inevitably encounter vibration. In some embodiments, the mounting base 109 can prevent the locking pin 107 at the first angle from rotating, so as to prevent the lock 104 from being unlocked by vibration, thereby preventing the door 103 of the logistics container 101 from being accidentally opened due to vibration, and thus preventing the items in the logistics container 101 from falling to the outside of the logistics container 101.
[0058] like Figure 10As shown, the mounting base 109 includes an upper horizontal plate 127, a lower horizontal plate 128, and a vertical plate 129. The upper and lower ends of the vertical plate 129 are connected to the upper horizontal plate 127 and the lower horizontal plate 128, respectively. The mounting base 109 has a first limiting hole 130, which can be located at the upper horizontal plate 127. The first limiting hole 130 is a through hole. Figure 5 As shown, the locking pin 107 includes a limiting part 115, a first rod part 116, and a second rod part 117. The first rod part 116 and the second rod part 117 are respectively connected to the two ends of the locking part 113. The first rod part 116 is located between the limiting part 115 and the locking part 113. The limiting part 115 and the locking part 113 are relatively fixed and spaced apart along the axial direction of the locking pin 107. When the lock 104 is in the locked state, the limiting part 115 is located inside the first limiting hole 130. The inner wall surface of the first limiting hole 130 can contact the outer peripheral surface of the limiting part 115 to prevent the locking pin 107 from rotating, thereby keeping the locking pin 107 at a first angle to prevent the lock 104 from being accidentally unlocked due to vibration. When the lock 104 is in the unlocked state, the limiting part 115 is located outside the first limiting hole 130, at which time the locking pin 107 can rotate.
[0059] In this embodiment, the limiting part 115, the locking part 113, and the first limiting hole 130 are all oblong in shape, which helps to reduce the shape complexity and processing difficulty of the locking pin 107 and the mounting base 109. The outer peripheral surface of the limiting part 115 includes two opposing third surfaces and two opposing arc surfaces, and the hole wall of the first limiting hole 130 includes two opposing first surfaces 120 and two opposing arc surfaces. The third surfaces are planar and parallel to the rotation axis, and the first limiting surfaces 131 are planar and parallel to the rotation axis. The first surfaces 120 and the first limiting surfaces 131 can contact each other, thereby hindering the rotation of the locking pin 107.
[0060] like Figure 10 As shown, the mounting base 109 also has a second limiting hole 132, which can be located at the lower horizontal plate 128 and is a through hole. When the lock 104 is in the locked state, a part of the locking part 113 is located inside the second limiting hole 132, and the inner wall surface of the second limiting hole 132 can contact the outer peripheral surface of the locking part 113 to prevent the locking pin 107 from rotating, thereby keeping the locking pin 107 at the first angle to prevent the lock 104 from being accidentally unlocked due to vibration. When the lock 104 is in the unlocked state, the locking part 113 is located outside the second limiting hole 132, and the locking pin 107 can rotate at this time. Since the mounting base 109 is provided with both the first limiting hole 130 and the second limiting hole 132, the limiting effect of the mounting base 109 on the locking pin 107 is better. In some other embodiments, in order to limit the locking pin 107, only the first limiting hole 130 or only the second limiting hole 132 may be provided.
[0061] In this embodiment, both the locking part 113 and the second limiting hole 132 are oblong in shape, which helps to reduce the shape complexity and manufacturing difficulty of the locking pin 107 and the mounting base 109. The outer peripheral surface of the locking part 113 includes two first surfaces 120, which are planar and parallel to the rotation axis. The hole wall of the second limiting hole 132 includes two second limiting surfaces 133, which are planar and parallel to the rotation axis. The first surfaces 120 and the first limiting surfaces 131 can contact each other, thereby hindering the rotation of the locking pin 107.
[0062] like Figure 11 As shown, the lock 104 also includes an elastic element 110, and both the mounting base 109 and the locking pin 107 are connected to the elastic element 110. For example, the locking pin 107 also includes an anti-disengagement part 114, which is detachably connected to the second rod part 117. The anti-disengagement part 114 can be a nut, and the outer peripheral surface of the second rod part 117 has threads. The connection between the anti-disengagement part 114 and the second rod part 117 is a threaded connection. The elastic element 110 is fitted over the second rod part 117, with its top end abutting against the bottom surface of the lower horizontal plate 128 and its bottom end abutting against the top surface of the anti-disengagement part 114.
[0063] It should be noted that the installation method of the elastic element 110 is not limited to the above-described method. For example, in some other embodiments not shown, both ends of the elastic element 110 are connected to the upper horizontal plate 127 and the knob part 112 respectively (e.g., by bonding, snap-fitting, or welding, etc.). After the locking pin 107 moves upward, the tension of the elastic element 110 drives the locking pin 107 to move downward and reset. The installation methods of the elastic element 110 are not listed here.
[0064] The elastic force of the elastic element 110 drives the locking pin 107 to move axially, so that the limiting part 115 enters the first limiting hole 130. When the mounting base 109 has a second limiting hole 132, the elastic force of the elastic element 110 also drives the locking part 113 into the second limiting hole 132. After the user releases the locking pin 107, the elastic element 110 allows the locking pin 107 to automatically reset, eliminating the need for the user to manually insert the limiting part 115 and the locking part 113 into the first limiting hole 130 and the second limiting hole 132 respectively. Therefore, the elastic element 110 improves the ease of operation of the lock 104.
[0065] Taking the process of lock 104 switching from the locked state to the unlocked state as an example, the following will demonstrate... Figure 11 Explain the position and angle changes of the locking pin 107, and explain how the elastic element 110 works.
[0066] Please refer to Figure 11 (a) to Figure 11(b) When the user needs to unlock, the user grasps the knob 112 and lifts the locking pin 107 upwards until the limiting part 115 disengages from the first limiting hole 130 and the bottom end of the locking part 113 disengages from the second limiting hole 132. It should be noted that after the locking pin 107 is lifted upwards (as...), Figure 11 (b) As shown, the top of the locking part 113 is not inserted into the first limiting hole 130, and the elastic member 110 is in a compressed state at this time.
[0067] Then, please refer to Figure 11 (b) to Figure 11 (c) The user rotates the locking pin 107 (e.g., rotates it 90°) to the second angle. When the locking pin 107 is at the second angle, the limiting part 115 and the first limiting hole 130 intersect each other, and the locking part 113 and the second limiting hole 132 intersect each other. Next, the user releases the hand, and the locking pin 107 moves downward under the action of gravity and the elastic force of the elastic member 110. Finally, the limiting part 115 rests on the upper horizontal plate 127, and the locking part 113 rests on the lower horizontal plate 128. In this way, the limiting part 115 remains outside the first limiting hole 130, and the locking part 113 remains outside the second limiting hole 132. When the locking pin 107 is in the second angle... Figure 11 In the state shown in (c), gate 103 can move.
[0068] During the process of lock 104 switching from the unlocked state to the locked state, the position and angle of lock pin 107 change in the same way as... Figure 11 The process is the reverse. Assuming door 103 is closed and the locking pin 107 is in the notch 111, when the user needs to lock the door, the user grasps the knob 112 and rotates the locking pin 107, thereby rotating the locking pin 107 to the position shown. Figure 11 (b) shows the state (locking pin 107 is at the first angle). Then, the user releases the locking pin 107, which moves downwards under the influence of gravity and the elastic force of the elastic element 110. The limiting part 115 inserts into the first limiting hole 130, and the bottom end of the locking part 113 inserts into the second limiting hole 132. The knob part 112 rests on the upper horizontal plate 127 to prevent the locking pin 107 from falling off the mounting base 109. In this way, the locking pin 107 returns to its original position as shown in the diagram. Figure 11 (a) shows the state, thereby locking the latch 108.
[0069] It should be noted that in the embodiment shown in the accompanying drawings, the axial direction of the locking pin 107 is vertical. In other embodiments not shown, the axial direction of the locking pin 107 may also be horizontal, or it may be a direction inclined relative to the horizontal plane. When the axial direction of the locking pin 107 is horizontal, gravity does not drive the locking pin 107 to reset; only the elastic force of the elastic element 110 drives the locking pin 107 to reset.
[0070] Furthermore, although the user needs to pull and rotate the locking pin 107 to unlock it due to the presence of the limiting part 115 and two limiting holes, the distance the locking pin 107 is pulled is short, and it does not require significant movement along its own axis. Moreover, during locking, the user only needs to rotate the locking pin 107 and release it; there is no need for the user to push or pull the locking pin 107 axially. Therefore, considering both locking and unlocking convenience, the lock 104 of this invention is still superior in ease of use. Figure 9 The prior art shown.
