Description

Technical Field

[0001] The utility model relates to the field of cooking utensils, in particular to a shoulder strap assembly and a container. Background Art

[0002] At present, the portable pots on the market are generally provided with a strap for easy carrying. The two ends of the strap are respectively wrapped around a Japanese buckle, which is fixed at a fixed position of the pot body. When cleaning the strap, if the strap is not removed, it will get wet, affecting the use. If the strap is removed, it needs to be untied from the Japanese buckle, which is troublesome and time-consuming. In addition, if the strap and the Japanese buckle are not wrapped properly, there is a risk that the strap will separate from the pot body. Utility Model Content

[0003] Therefore, an object of the present invention is to provide a shoulder strap assembly and a container to at least solve one of the problems existing in the above-mentioned related art.

[0004] One aspect of an embodiment of the utility model provides a shoulder strap assembly for connecting a container body, the shoulder strap assembly comprising: a shoulder strap, comprising a strap body and a buckle connected to the strap body; a mounting seat, for being coupled to the container body, the mounting seat being provided with a buckle slot, the buckle being detachably inserted into the buckle slot; a locking assembly, arranged on the mounting seat, the locking assembly being capable of limiting the buckle in the buckle slot, and the locking assembly being capable of releasing the limitation on the buckle.

[0005] The strap assembly provided in this embodiment realizes the connection between the strap body and the mounting seat by inserting the buckle into the buckle slot. Compared with the strap body wrapped around the Japanese buckle in the related art, this plug-in and pull-out method is more convenient to operate and saves time. In addition, the buckle is limited by the locking assembly when the buckle is inserted into the buckle slot, and the buckle is locked in the buckle slot, which improves the installation stability of the strap. Therefore, when the strap assembly is installed on a container body, such as a pot body, the probability of the strap body being separated from the pot body and causing the pot body to fall and break can be reduced. When the strap body needs to be disassembled, the locking assembly releases the limit on the buckle, and the buckle can be pulled out of the buckle slot, which is convenient for disassembly.

[0006] In addition, the shoulder strap assembly provided in the above embodiment of the present application may also have the following additional technical features:

[0007] In some embodiments, the buckle is provided with a buckle hole, and the locking assembly includes an insert tongue, which can be inserted into the buckle hole and locked with the buckle. The insert tongue is inserted into the buckle hole to limit the buckle, and the locking effect is good, and the structure is simple and easy to process.

[0008] In some embodiments, the locking assembly further includes an elastic member, and the inserting tongue can be retained in the button hole under the elastic force of the elastic member.

[0009] In these embodiments, when the inserting tongue is inserted into the button hole, the inserting tongue is retained in the button hole by the elastic force of the elastic member, thereby improving the limiting effect. Moreover, the inserting tongue is inserted into the button hole under the elastic force of the elastic member, and when the shoulder strap is lifted, even if the container body is heavy, the inserting tongue will not easily slip out of the button hole under the action of external force, and the elastic force of the elastic member needs to be overcome, thus facilitating the shoulder strap to stably lift the container body.

[0010] In some embodiments, the surface of the inserting tongue facing the insertion direction of the buckle has a guide surface, and the guide surface gradually extends toward the bottom of the inserting tongue from the tongue root direction to the tongue tip direction of the inserting tongue. The guide surface can guide the inserting tongue to retreat to one side of the buckle under the pressure of the buckle until it is inserted into the buckle hole when it corresponds to the buckle hole. The design of the guide surface can prevent the buckle from interfering with the inserting tongue during the process of inserting the buckle slot, which is conducive to the smooth retreat of the inserting tongue and then inserting it into the buckle hole.

[0011] In some embodiments, the locking assembly further includes an unlocking key, through which the inserting tongue can be pushed to overcome the elastic force of the elastic member so that the inserting tongue can be withdrawn from the buckle hole. It is convenient for the user to unlock the locking assembly by triggering the unlocking key, and the operation is convenient.

[0012] In some embodiments, the unlocking key is a press key, the elastic member is a compression spring, the elastic member is located on the inner side of the inserting tongue, the unlocking key is located on the outer side of the inserting tongue, the unlocking key is connected to the inserting tongue in an insertion area that avoids the buckle, and the unlocking key can also be reset under the elastic force of the elastic member.

[0013] In these embodiments, the unlocking key is a press key. By pressing the unlocking key, the insert tongue can be pushed to move out of the buckle hole through the unlocking key to achieve unlocking. The operation is convenient and the belt body can be quickly disassembled. The unlocking key avoids the insertion area of ​​the buckle to connect with the insert tongue. On the one hand, it can drive the insert tongue to move, and on the other hand, it can ensure that the buckle is inserted into the buckle slot without interfering with the unlocking key. In addition, when the user does not apply pressure to the unlocking key, the unlocking key can be reset under the elastic force of the elastic member, which has the effect of beautifying the appearance regardless of whether the buckle is inserted into the buckle slot. Moreover, the elastic member is compressed during the process of pressing the unlocking key, which will also increase the pressing feel and improve the user experience.

[0014] In some embodiments, the shoulder strap assembly further includes a first safety lock, which can lock the locking assembly in a state of limiting the buckle, and unlock the locking assembly.

[0015] In these embodiments, a first safety lock is used to lock the locking assembly when the buckle is limited, which has a double insurance effect. It can prevent the locking assembly from being accidentally unlocked, causing the belt body to separate from the container body, and improve the connection stability of the shoulder strap and the mounting seat.

[0016] In some embodiments, the first safety lock is movably disposed on the mounting seat and can move between a locked position and an unlocked position. The first safety lock has a protruding first stopper, and the unlocking key or the plug tongue has a protruding second stopper. When the first safety lock is in the locked position, the first stopper and the second stopper are arranged in a positional manner to prevent the unlocking key from being pressed. When the first safety lock is in the unlocked position, the first stopper and the second stopper are staggered to allow the unlocking key to be pressed. The first safety lock uses a stopper to prevent the unlocking key or the plug tongue from moving, and has a good limiting effect, which can prevent the unlocking key from being accidentally touched and unlocked, and has a simple structure.

[0017] In some embodiments, a safety lock slot is provided on the mounting seat, the safety lock slot is connected to the buckle slot, the first safety lock is embedded in the safety lock slot, and can move between a locked position and an unlocked position along the slot side wall of the safety lock slot.

[0018] In these embodiments, the safety lock slot is used to limit the movement of the first safety lock, ensuring that the first safety lock moves along a set path and accurately reaches the locked position and the unlocked position.

[0019] In some embodiments, two limit grooves are spaced apart on the side walls of the safety lock slot, and the positions of the two limit grooves correspond to the locking position and the unlocking position respectively. A stop protrusion is provided on one side of the first safety lock, and the stop protrusion can move between the two limit grooves and be inserted into the limit groove at the corresponding position.

[0020] In these embodiments, when locking by the first safety lock, it is necessary to overcome the friction between the stop protrusion and the side wall of the groove of the safety lock slot to move the first safety lock until the stop protrusion moves to and extends into the corresponding limiting groove, so that the first safety lock moves to the locked position or the unlocked position. When the user turns the first safety lock, in addition to the squeezing of the stop protrusion and the side wall of the groove, the stop protrusion will be stuck when it is released into the limiting groove, and it is necessary to increase the force to make the stop protrusion disengage from the limiting groove, so that the user can determine whether the first safety lock has moved into place according to the movement feedback of the first safety lock. Moreover, when the stop protrusion extends into the limiting groove, the limiting groove can also limit the stop protrusion. Since a certain force needs to be applied to move the first safety lock out of the corresponding limiting groove, it can avoid the first safety lock from accidentally moving and losing the locking effect.

[0021] In some embodiments, the first safety lock includes an operating portion and an insertion portion extending from the operating portion, the insertion portion extends into the safety lock slot, and the operating portion is located outside the safety lock slot. Here, the insertion portion can be used to lock the locking assembly, while the operating portion is used for the user to touch, so that the user can touch the operating portion to lock or unlock.

[0022] In some embodiments, the insertion portion includes at least two elastic claws extending into the safety lock slot, and the at least two elastic claws are distributed on both sides of the safety lock slot in the width direction and overlap the inner edge of the safety lock slot to prevent the first safety lock from falling off from the safety lock slot. The design of the elastic claws can prevent the first safety lock from falling off from the safety lock slot and will not affect the sliding of the first safety lock along the safety lock slot.

[0023] In some embodiments, the inserting portion further comprises a first stop post extending into the safety lock slot, and the free end of the first stop post is configured as a first stop portion. The structure is simple and convenient for processing.

[0024] In some embodiments, the inserting portion further comprises a second stop column extending into the safety lock slot, and the stop protrusion is formed on the second stop column structure. The structure is simple and convenient for processing.

[0025] In some embodiments, the notch of the buckle slot is facing upward, the buckle is inserted into the buckle slot downward in a vertical direction, the insert tongue is inserted into or withdrawn from the buckle hole from one side of the buckle along a first horizontal direction, the unlocking key is located on the other side of the buckle in the first horizontal direction, pushing the insert tongue to withdraw from the buckle hole, the first safety lock is located below the buckle, and the first safety lock can move between a locked position and an unlocked position along a second horizontal direction perpendicular to the first horizontal direction.

[0026] In these embodiments, the insertion opening of the buckle slot faces upward, so that the buckle can be aligned with the buckle slot and inserted therein, and the operation is convenient and quick. The unlocking key moves in the first horizontal direction and can be set on the side of the mounting seat. Compared with the unlocking key being set on the upper surface or the lower surface of the mounting seat, the risk of the unlocking key being accidentally touched can be reduced, and it can be kept away from the container body, especially when the container body is a pot body, which can reduce the risk of the user being scalded by the pot body or the hot air emitted from the pot body.

[0027] In some embodiments, the mounting seat is annular, and the buckle slots are distributed on two opposite sides of the mounting seat in a radial direction. Then, two ends of the belt body are connected to two opposite ends of the mounting seat, so that the container body can be stably lifted using the mounting seat.

[0028] In some embodiments, the inner side of the mounting seat has a clamping portion, and the clamping portion is used to clamp and fix with the container body. The mounting seat and the container body are connected by clamping, and the connection stability is good.

[0029] In some embodiments, the mounting seat is further provided with an external thread, which is higher than the buckle slot and is used to be screwed together with the container cover. Compared with the connection between the container cover and the container body, it is unnecessary to provide a corresponding connection structure on the container body, thus simplifying the container body and facilitating processing.

[0030] A second aspect of the present invention provides a container, which includes a container body and a shoulder strap assembly as described in any one of the above embodiments, wherein a mounting seat is mounted on the container body.

[0031] The container provided in the embodiment of this aspect has the shoulder strap assembly of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0032] Other aspects and / or advantages of the general inventive concept will be partially set forth in the following description, and some will be clear from the description or may be learned through implementation of the general inventive concept. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The pot-carrying products or thermal insulation boxes with straps in the related art all have a Japanese-shaped buckle fixed on the pot body or the thermal insulation box, and the end of the strap is wrapped around the Japanese-shaped buckle to achieve the connection between the strap body and the Japanese-shaped buckle. Since the pot body and the thermal insulation box usually need to hold food and need to be cleaned, the strap body needs to be disassembled to prevent the strap body from being wetted by water. However, it is troublesome to untie the strap body from the Japanese-shaped buckle, which wastes time. The subsequent process of wrapping the strap body around the Japanese-shaped buckle again is also troublesome. Moreover, once the strap body and the Japanese-shaped buckle are not wrapped well, there is a risk that the strap body and the Japanese-shaped buckle will separate, which can easily cause the pot body or the thermal insulation box to fall and be damaged.

[0067] Based on this, the embodiment of the present application provides a shoulder strap assembly, which is easy to assemble and disassemble and has good installation stability. The shoulder strap assembly is used to connect the container body of the container. The container can be a pot, a thermos pot, etc., but is not limited thereto. Figures 1 to 16 , taking a pot as an example, the shoulder strap assembly provided by an embodiment of the utility model is introduced.

[0068] like Figures 1 to 4 , Figure 7 and Figure 8 As shown, one embodiment of the utility model provides a shoulder strap assembly, which includes a shoulder strap 30, a mounting seat 20 and a locking assembly 40. The shoulder strap 30 includes a belt body 310 and a buckle 320 connected to the belt body 310. The mounting seat 20 is used to be combined with the container body 10, and the mounting seat 20 is provided with a buckle slot 210, and the buckle 320 is detachably inserted into the buckle slot 210. The locking assembly 40 is provided on the mounting seat 20, and the locking assembly 40 can limit the buckle 320 in the buckle slot 210, and the locking assembly 40 can also release the limit of the buckle 320.

[0069] The strap assembly provided in this embodiment connects the strap body 310 and the mounting seat 20 by inserting the buckle 320 into the buckle slot 210. Compared with the strap body 310 being wrapped around the Japanese buckle in the related art, this plug-in and pull-out method is more convenient to operate and saves time. Moreover, the buckle 320 is limited by the locking assembly 40 when the buckle 320 is inserted into the buckle slot 210, and the buckle 320 is locked in the buckle slot 210, thereby improving the installation stability of the strap 30. Therefore, when the strap assembly is installed on the container body 10, such as a pot body, the probability of the strap body 310 being separated from the pot body and causing the pot body to fall and break can be reduced. When the strap body 310 needs to be disassembled, the locking assembly 40 releases the limit on the buckle 320, and the buckle 320 can be pulled out from the buckle slot 210, which is convenient for disassembly.

[0070] Furthermore, since the method of disassembling the belt body 310 does not require separating the belt body 310 and the buckle 320, the belt body 310 and the buckle 320 can be fixed together, for example, the belt body 310 and the buckle 320 are connected together by a sewing process, thereby improving the connection stability between the two and reducing the probability of the belt body 310 being separated from the mounting seat 20 due to separation from the buckle 320.

[0071] As an example, one end of the buckle 320 has a through hole, one end of the belt body 310 extends into the through hole and bends back to be sewn together with the portion of the belt body 310 that does not extend into the through hole, and the connection stability between the belt body 310 and the buckle 320 is good.

[0072] Regarding the specific structure of the locking assembly 40, further, in some embodiments, as Figure 2 and Figure 4 As shown, a buckle hole 321 is provided on the buckle 320 , and the locking assembly 40 includes an inserting tongue 420 , which can be inserted into the buckle hole 321 and locked with the buckle 320 .

[0073] In these embodiments, the locking assembly 40 limits the buckle 320 by inserting the inserting tongue 420 into the buckle hole 321 , which has a good limiting effect, a simple structure, and is easy to process.

[0074] Here, the buckle hole 321 can be a through hole, and the insert tongue 420 can pass through the through hole and the buckle 320. On the one hand, the locking assembly 40 can effectively limit the buckle 320, and on the other hand, when the shoulder strap 30 is lifted, even if the container body 10 is very heavy, the insert tongue 420 can be used to stably hang on the buckle 320, thereby reducing the risk of separation between the container body 10 and the belt body 310.

[0075] Of course, the buckle hole 321 may also be a countersunk hole, as long as it has a sufficient depth to be fully engaged with the inserting tongue 420 to ensure that the buckle 320 will not be easily separated from the mounting seat 20.

[0076] In some embodiments, the tongue 420 is inserted into the buckle hole 321 under the push of the outside world (such as the user), and is also withdrawn from the buckle hole 321 under the pull of the outside world. The user directly or indirectly moves the tongue 420 to limit the buckle 320. The locking assembly 40 has a simple structure and is easy to process. However, in some cases, such as when the container body 10 is heavy or the container body 10 is tilted, once the user moves away from the tongue 420, the tongue 420 is not restricted and can easily withdraw from the buckle hole 321, resulting in failure of the limit.

[0077] At this time, in order to prevent the tongue 420 from easily escaping from the button hole 321, a convex rib (not shown in the figure) can be provided on the tongue 420, and the convex rib is used to clamp the edge of the button hole 321. When the buckle 320 needs to be limited, the user forcibly pushes the tongue 420 and the convex rib through the button hole 321, and then if the tongue 420 retreats, the edge of the button hole 321 can limit the convex rib, thereby preventing the tongue 420 from easily escaping from the button hole 321. Although this design can reduce the probability of the tongue 420 escaping from the button hole 321 to a certain extent, there is still a risk of failure of the limit, and a large force needs to be applied to the tongue 420 during the process of limiting and releasing the limit, which increases the difficulty of operation. Moreover, after repeated use, the button hole 321 is easily squeezed and deformed by the convex rib, and there is also a risk of failure of the limit.

[0078] To improve the locking stability of the insert tongue 420, further, in some other embodiments, as Figure 2 and Figure 4 As shown, the locking assembly 40 further includes an elastic member 410, and the insert tongue 420 can be retained in the buckle hole 321 under the elastic force of the elastic member 410. Further, the insert tongue 420 can also be automatically inserted into the buckle hole 321 under the elastic force of the elastic member 410.

[0079] In these embodiments, the insert tongue 420 is inserted into the buckle hole 321 with the help of the elastic force of the elastic member 410. Compared with the case where the insert tongue 420 is inserted into the buckle hole 321 under the force of the user and the insert tongue 420 is not restricted after the user detaches from the insert tongue 420, the insert tongue 420 can be ensured to remain in the buckle hole 321, thereby improving the limiting effect on the buckle 320. Moreover, the insert tongue 420 is always inserted into the buckle hole 321 under the elastic force of the elastic member 410. When lifting the shoulder strap 30, even if the container body 10 is heavy, the insert tongue 420 will not easily slide out of the buckle hole 321 under the action of external force, and the elastic force of the elastic member 410 must be overcome. Therefore, it is beneficial for the shoulder strap 30 to stably lift the container body 10.

[0080] As an example, Figure 2 and Figure 4 As shown, the elastic member 410 is a compression spring, which pushes the inserting tongue 420 to insert into the buckle hole 321 .

[0081] As an example, the elastic member 410 is a tension spring, which pulls the inserting tongue 420 to insert into the buckle hole 321 .

[0082] In a specific application, when the buckle 320 is inserted into the buckle slot 210, the buckle 320 will squeeze the tongue 420 and move it back until the buckle hole 321 on the buckle 320 moves to the position of the tongue 420, and then the tongue 420 moves in the reset direction under the elastic force of the elastic member 410 and is inserted into the buckle hole 321. In order to make the tongue 420 insert into the buckle hole 321 more smoothly, the surface of the tongue 420 facing the notch of the buckle slot 210 may have a guiding arc surface or a guiding inclined surface, so as to facilitate squeezing the tongue 420 and moving it back during the insertion of the buckle 320.

[0083] In order to facilitate the smooth insertion of the inserting tongue 420 into the buckle hole 321, further, the surface of the inserting tongue 420 facing the insertion direction of the buckle 320 can be provided with a guide surface 421, and the guide surface 421 gradually extends toward the bottom of the inserting tongue 420 from the tongue root direction of the inserting tongue 420 to the tongue tip direction of the inserting tongue 420. The guide surface 421 can guide the inserting tongue 420 to retreat to one side of the buckle 320 under the pressure of the buckle 320 until it is inserted into the buckle hole 321 when it corresponds to the buckle hole 321. The design of the guide surface 421 can prevent the buckle 320 from interfering with the inserting tongue 420 during the process of inserting the buckle 320 into the buckle slot 210, and is conducive to the smooth retreat of the inserting tongue 420 and then inserting it into the buckle hole 321.

[0084] Figure 2 A partial cross-sectional view of the strap assembly is shown when the tongue 420 is inserted into the buckle hole 321. Figure 4 FIG. 4 is a partial cross-sectional view of the insert tongue 420 when it exits the button hole 321. Figure 4 The surface of the tongue 420 facing the notch of the buckle slot 210 has a guide surface 421, which facilitates the buckle 320 to be inserted downward into the buckle slot 210 and squeezes the tongue 420 to retreat to the left side in the figure. The elastic member 410 is compressed until the buckle hole 321 of the buckle 320 moves down to a position opposite to the tongue 420. Figure 2 The insert tongue 420 is inserted into the buckle hole 321 under the elastic force of the elastic member 410 , and the buckle 320 is restricted from being pulled out of the buckle slot 210 .

[0085] To facilitate unlocking of the locking assembly 40, further, in some embodiments, as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the locking assembly 40 further includes an unlocking key 430, through which the inserting tongue 420 can be pushed to overcome the elastic force of the elastic member 410, so that the inserting tongue 420 can be withdrawn from the buckle hole 321. It is convenient for the user to unlock the locking assembly 40 by triggering the unlocking key 430, and release the limit of the buckle 320, which is easy to operate.

[0086] Further, the unlocking key 430 can be a push button, a lever, a knob, etc. The unlocking key 430 is movably arranged on the mounting base 20.

[0087] Further, the unlocking key 430 can be arranged on the upper surface, the outer side surface or the lower surface of the mounting base 20.

[0088] In some embodiments, as Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, the unlocking key 430 is a push button, the elastic member 410 is a compression spring, the elastic member 410 is located inside the tongue 420, the unlocking key 430 is located outside the tongue 420, the unlocking key 430 is connected to the tongue 420 in the insertion area avoiding the buckle 320, and the unlocking key 430 can also be reset under the elastic force of the elastic member 410.

[0089] In these embodiments, the unlocking key 430 is a push button. Pressing the unlocking key 430 can move the tongue 420 through the unlocking key 430 to withdraw from the buckle hole 321 and release the limit, which is convenient to operate and convenient for quickly disassembling the belt body 310. The unlocking key 430 is connected to the tongue 420 in the insertion area avoiding the buckle 320. On the one hand, it can drive the tongue 420 to move, and on the other hand, it can ensure that the buckle 320 is inserted into the buckle slot 210 without interfering with the unlocking key 430. In addition, when the user does not apply pressure to the unlocking key 430, the unlocking key 430 can be reset under the elastic force of the elastic member 410, which has the effect of beautifying the appearance whether the buckle 320 is inserted into the buckle slot 210 or not. Moreover, during the process of pressing the unlocking key 430, the elastic member 410 is compressed, which will also increase the pressing feel and improve the user experience.

[0090] Further, the unlocking key 430 and the tongue 420 can be of a split structure, and the two are independently processed and formed, which simplifies the mold and is convenient for processing. Or further, the unlocking key 430 and the tongue 420 are integrally formed to ensure that the unlocking key 430 can drive the tongue 420 to move synchronously.

[0091] Regarding the specific structures of the unlocking key 430 and the tongue 420, as an example, the unlocking key 430 is generally in a U shape with an upward opening, the tongue 420 is located on one side of the U shape and extends towards the inside of the U shape, and the other side of the U shape is exposed outside the mounting base 20 for the user to press, and the space in the middle of the U shape is convenient for the buckle 320 to be inserted.

[0092] As an example, the width of the unlocking key 430 is greater than the width of the buckle 320. The two ends of the unlocking key 430 in the width direction cross the insertion area of the buckle 320 and are connected to the tongue 420, and there is a gap for the buckle 320 to be inserted between the tongue 420 and the unlocking key 430.

[0093] As an example, the unlocking key 430 is roughly a square body with an opening at the top. The buckle 320 is inserted into the inner space of the square body through the opening. The outer side of the square body is for the user to press. The tongue 420 is connected to the inner wall of the square body and extends to the middle of the opening.

[0094] The specific structure of the unlocking key 430 and the inserting tongue 420 is not limited to the above embodiment, and there may be a variety of connection modes, which are not listed here one by one.

[0095] In addition, in order to prevent the unlocking key 430 from being pushed out of the mounting seat 20 by the elastic member 410 and falling off, refer to Figure 5 and Figure 6 , a mounting port 220 can be provided on the mounting seat 20, the mounting port 220 is communicated with the buckle slot 210, the unlocking key 430 is embedded in the mounting port 220 and extends into the buckle slot 210, the unlocking key 430 has hooks 431 on both sides of the width direction, and the buckle slot 210 has slide grooves 230 on both sides of the width direction, the hook 431 moves in the slide groove 230, and is limited by the slide groove 230, which can effectively prevent the unlocking key 430 from falling off the mounting seat 20. When installing the unlocking key 430, the unlocking key 430 can be forcibly pushed in until a click sound is heard, and the hook 431 enters the slide groove 230. Of course, in order to prevent the unlocking key 430 from falling, a protrusion can also be provided at the end of the slide groove 230 facing the mounting port 220, and the side wall of the slide groove 230 and the protrusion are used to limit the hook 431 at the same time, and the limiting effect is good.

[0096] To prevent the buckle 320 from being accidentally disengaged from the buckle slot 210, further, in some embodiments, as Figures 9 to 14 As shown, the shoulder strap assembly further includes a first safety lock 50 , which can lock the locking assembly 40 in a state of limiting the buckle 320 , and can also unlock the locking assembly 40 .

[0097] In these embodiments, the first safety lock 50 is used to lock the locking assembly 40 when the buckle 320 is limited, which has a double insurance effect. It can prevent the locking assembly 40 from being separated from the belt body 310 and the container body 10 due to accidental touching, and improve the connection stability between the shoulder strap 30 and the mounting seat 20.

[0098] Regarding the locking and unlocking methods of the first safety lock 50, in some embodiments, the first safety lock 50 is movably disposed on the mounting base 20 and can move between a locked position and an unlocked position; when the first safety lock 50 is in the locked position, the first safety lock 50 can limit the movement of the insert tongue 420 or the unlocking key 430, and when the first safety lock 50 is in the unlocking position, the first safety lock 50 releases the limitation on the insert tongue 420 or the unlocking key 430.

[0099] When the locking assembly 40 includes the inserting tongue 420 and the unlocking key 430, the first mounting assembly can restrict the inserting tongue 420 that has been inserted into the button hole 321 from exiting the button hole 321, or restrict the movement of the unlocking key 430, thereby preventing the unlocking key 430 from being accidentally touched and unlocking.

[0100] In some embodiments, Fig.12 , Fig.13 , Fig.14 , Fig.15 and Fig.16 As shown, the first safety lock 50 has a protruding first stopper 510, and the unlocking key 430 or the inserting tongue 420 has a protruding second stopper 440. When the first safety lock 50 is in the locked position, the first stopper 510 and the second stopper 440 are arranged in a positional manner to prevent the unlocking key 430 from being pressed. When the first safety lock 50 is in the unlocked position, the first stopper 510 and the second stopper 440 are staggered to allow the unlocking key 430 to be pressed. The first safety lock 50 uses a stopper to prevent the unlocking key 430 or the inserting tongue 420 from moving, which has a good limiting effect and a simple structure.

[0101] Fig.13 A longitudinal partial cross-sectional schematic diagram of the shoulder strap assembly is shown when the first safety lock 50 is in the unlocked position. Fig.14 A longitudinal partial cross-sectional view of the harness assembly is shown when the first safety lock 50 is in the locked position. Fig.13 and Fig.14 , the notch of the buckle slot 210 faces upward, and the buckle 320 is inserted into the buckle slot 210 from top to bottom. The insert tongue 420 is arranged on the left side of the buckle 320 in the figure, and the elastic member 410 is located on the left side of the insert tongue 420 in the figure, pushing the insert tongue 420 to insert into the buckle hole 321, and the unlocking key 430 is located on the right side of the buckle 320 in the figure, and passes over the buckle 320 from the bottom of the buckle 320 to connect with the insert tongue 420. The first safety lock 50 is arranged below the buckle 320. Except for the first stop portion 510, the first safety lock 50 is lower than the inserting tongue 420. The bottom of the inserting tongue 420 has a second stop portion 440 protruding downward. In other words, the first stop portion 510 and the second stop portion 440 are at the same height. When the first safety lock 50 is pushed along the width direction of the inserting tongue 420, the first stop portion 510 can be moved to one side of the second stop portion 440 for alignment, so as to prevent the inserting tongue 420 from exiting the buckle hole 321 to the left and prevent the unlocking key 430 from being pressed and moved. The first stop portion 510 can also be kept away from the second stop portion 440. The two are staggered. In this way, when the unlocking key 430 is pressed to the left, the unlocking key 430 can push the inserting tongue 420 to move to the left to exit the buckle hole 321 without interfering with the first stop portion 510. Fig.15 and Fig.16FIG. 1 shows a longitudinal partial cross-sectional view of the first safety lock 50 in the unlocked position. Fig.15 and Fig.16 The first stopper 510 and the second sub-stopper are arranged alternately. Even if the unlocking key 430 is pressed, the first stopper 510 will not block the second stopper 440, thereby blocking the unlocking key 430 and the insertion tongue 420 from moving, making it easier for the insertion tongue 420 to exit the buckle hole 321. When the first safety lock 50 is needed to lock the locking assembly 40, the first installation lock can be moved in the direction of the arrow in the figure to move the first stopper 510 to one side of the second stopper 440 and set in alignment. In this way, even if the unlocking key 430 is pressed inward, the first stopper 510 will prevent the unlocking key 430 from being pressed.

[0102] In some embodiments, Fig.13 and Fig.14 As shown, a safety lock slot 240 is provided on the mounting base 20, and the safety lock slot 240 is connected to the buckle slot 210. The first safety lock 50 is embedded in the safety lock slot 240 and can move between a locked position and an unlocked position along the groove side wall of the safety lock slot 240.

[0103] In these embodiments, the safety lock slot 240 is used to limit the movement of the first safety lock 50, ensuring that the first safety lock 50 moves along a set path and accurately reaches the locked position and the unlocked position.

[0104] In order to enable the first safety lock 50 to be accurately moved to the position, further, as Fig.14 , Fig.15 and Fig.16 As shown, two limit grooves 241 are spaced apart on the side wall of the safety lock slot 240, and the positions of the two limit grooves 241 correspond to the locking position and the unlocking position respectively. A stop protrusion 520 is provided on one side of the first safety lock 50, and the stop protrusion 520 can move between the two limit grooves 241 and be inserted into the limit groove 241 at the corresponding position.

[0105] In these embodiments, when locking by the first safety lock 50, it is necessary to overcome the friction between the stop protrusion 520 and the side wall of the safety lock slot 240 to move the first safety lock 50 until the stop protrusion 520 moves to and extends into the corresponding limiting slot 241, so that the first safety lock 50 moves to the locked position or the unlocked position. When the user turns the first safety lock 50, in addition to the stop protrusion 520 squeezing against the side wall of the slot, the stop protrusion 520 will be stuck when it is released into the limiting slot 241, and it is necessary to increase the force to make the stop protrusion 520 disengage from the limiting slot 241, so that the user can determine whether the first safety lock 50 has moved into place based on the movement feedback of the first safety lock 50. Moreover, when the stop protrusion 520 extends into the limiting groove 241, the limiting groove 241 can also limit the stop protrusion 520. Since a certain force needs to be applied to move the first safety lock 50 out of the corresponding limiting groove 241, the first safety lock 50 can be prevented from accidentally moving and losing the locking effect.

[0106] In a specific application, when the stop protrusion 520 moves to the corresponding limit groove 241, a clicking sound may be emitted there, which is also helpful in reminding the user that the stop protrusion 520 has moved into place.

[0107] Furthermore, if Fig. 9 , Fig.10 and Fig.11 As shown, a locking mark 250 is provided on the outer surface of the mounting base 20 corresponding to the locking position, and an unlocking mark 260 is provided corresponding to the unlocking position. An indication mark 540 is provided on the outer surface of the first safety lock 50. When the first safety lock 50 is moved to the locking position, the indication mark 540 is arranged relative to the locking mark 250. When the first safety lock 50 is moved to the unlocking position, the indication mark 540 is arranged relative to the unlocking mark 260. In order to facilitate the user to move the first safety lock 50, the indication mark 540 is aligned with the locking mark 250 or the unlocking mark 260 to move the first safety lock 50 into place.

[0108] Fig.10 The figure shows that the indicator mark 540 of the first safety lock 50 is aligned with the locking mark 250. In this state, the first stop portion 510 and the second stop portion 440 are arranged in alignment, and the stop protrusion 520 is inserted into a limit groove 241. The first safety lock 50 is in a locked state, restricting the movement of the locking assembly 40. Fig.11 FIG. 5 shows that the indicator mark 540 of the first safety lock 50 is aligned with the unlocking mark 260. In this state, the first stopper 510 and the second stopper 440 are staggered, and the stopper protrusion 520 is inserted into another limit groove 241. The first safety lock 50 is in the unlocking state, and the locking assembly 40 is released from movement. The first safety lock 50 can be moved along Fig.10 and Fig.11Move back and forth in the direction of the double arrows to lock and unlock.

[0109] Among them, the indicator mark 540 can be Fig.10 and Fig.11 The indicator mark 540 may also be a convex point or a convex rib, etc., but is not limited thereto. The locking mark 250 and the unlocking mark 260 may be Fig.10 and Fig.11 The circular convex dots in the figure may also be Chinese characters or convex ribs, etc., but are not limited thereto.

[0110] Regarding the specific structure of the first safety lock 50, in some embodiments, such as Fig.16 As shown, the first safety lock 50 includes an operating portion 530 and an insertion portion protruding from the operating portion 530, the insertion portion extends into the safety lock slot 240, and the operating portion 530 is located outside the safety lock slot 240. Here, the insertion portion can be used to lock the locking assembly 40, and the operating portion 530 is used for the user to touch, so that the user can touch the operating portion 530 to lock or unlock.

[0111] The insertion portion includes at least two elastic claws 550 extending into the safety lock slot 240, and the at least two elastic claws 550 are distributed on both sides of the width direction of the safety lock slot 240 and overlap the inner edge of the safety lock slot 240 to prevent the first safety lock 50 from falling off from the safety lock slot 240. The design of the elastic claws 550 can prevent the first safety lock 50 from falling off from the safety lock slot 240, and will not affect the sliding of the first safety lock 50 along the safety lock slot 240.

[0112] The inserting portion further comprises a first stop post extending into the safety lock slot 240, and a free end of the first stop post is configured as a first stop portion 510. The structure is simple and convenient for processing.

[0113] The inserting part further comprises a second stop column extending into the safety lock slot 240, and the stop protrusion 520 is formed on the second stop column structure. The structure is simple and convenient for processing.

[0114] In a specific embodiment, Figures 9 to 16 As shown, the notch of the buckle slot 210 faces upward, the buckle 320 is inserted into the buckle slot 210 downward in the vertical direction, the insert tongue 420 is inserted into the buckle hole 321 or withdrawn from the buckle hole 321 from one side of the buckle 320 along the first horizontal direction F1, the unlocking key 430 is located on the other side of the buckle 320 in the first horizontal direction F1, and pushes the insert tongue 420 to withdraw from the buckle hole 321, and the first safety lock 50 is located below the buckle 320, and the first safety lock 50 can move between the locked position and the unlocked position along the second horizontal direction F2 perpendicular to the first horizontal direction F1.

[0115] In this embodiment, the insertion opening of the buckle slot 210 faces upward, so that the buckle 320 is conveniently aligned with the buckle slot 210 and inserted therein, and the operation is convenient and quick. The unlocking key 430 moves in the first horizontal direction F1 and can be set on the side of the mounting seat 20. Compared with the unlocking key 430 being set on the upper surface or the lower surface of the mounting seat 20, the risk of the unlocking key 430 being accidentally touched can be reduced, and it can be kept away from the container body 10, especially when the container body 10 is a pot body, the risk of the user being scalded by the pot body or the hot air emitted from the pot body can be reduced.

[0116] To prevent the buckle 320 from accidentally disengaging from the buckle slot 210, further, in some embodiments, the shoulder strap assembly also includes a second safety lock (not shown in the figure), which can lock the buckle 320 in the buckle slot 210, and the second safety lock can also be unlocked to release the limit on the buckle 320.

[0117] In these embodiments, the second safety lock is used to limit the buckle 320 again to prevent the buckle 320 from being separated from the buckle slot 210. Combined with the locking assembly 40, the buckle 320 is double locked, which improves the installation stability of the shoulder strap 30 and the container body 10. Moreover, even if the user accidentally locks one of the locking assembly 40 and the second safety lock, the other one still limits the buckle 320, which is safe.

[0118] As an example, the second safety lock includes a lever movably arranged on the upper surface of the mounting seat 20. When the second safety lock is in the locked position, the lever is pressed on the surface of the buckle 320 exposed in the buckle slot 210. When the second safety lock is in the unlocked position, the lever is away from the buckle 320. The second safety lock directly uses the lever to press the buckle 320 into the buckle slot 210, which can prevent the buckle 320 from easily detaching from the buckle slot 210. Moreover, the second safety lock is located on the upper surface of the mounting seat 20, so it can be intuitively seen whether the lever has moved into place, thereby improving the locking accuracy.

[0119] The length of the lever can be greater than the width of the buckle 320, and the lever can be completely placed horizontally above the buckle 320 to press the buckle 320 into the buckle slot 210. For example, the portion of the buckle 320 exposed from the buckle slot 210 is roughly in the shape of a letter "I", one end of the lever can be rotatably arranged on the upper surface of the mounting seat 20, and the lever can be rotated to insert into the right opening of the bottom of the letter "I" to press the buckle 320 into the buckle slot 210.

[0120] Of course, the length of the lever can also be shorter. In this case, there can be multiple levers, which are pressed against the edge of the surface of the buckle 320 exposed in the buckle slot 210 to prevent the buckle 320 from detaching.

[0121] As an example, the second safety lock includes a lock hook, which is arranged outside the mounting seat 20, and a hook hole is arranged on the portion of the buckle 320 located outside the buckle slot 210, and the lock hook hooks the hook hole. The structure is simple and easy to process. In addition, it can prevent the buckle 320 from directly detaching from the buckle slot 210 after the locking assembly 40 fails to lock.

[0122] The above embodiments define a variety of specific structures of the locking assembly 40, the first safety lock 50 and the second safety lock. Of course, the protection scope of the present application is not limited thereto, and the locking assembly 40, the first safety lock 50 and the second safety lock may also have a variety of structural forms.

[0123] The above embodiment defines that the locking assembly 40 can limit the portion of the buckle 320 inserted into the buckle slot 210 to prevent the buckle 320 from being separated from the buckle slot 210. In other embodiments, the locking assembly 40 can limit the portion of the buckle 320 located outside the buckle slot 210. For example, the unlocking key 430 is an ear structure connected to the insert tongue 420 and tilted up, the insert tongue 420 and the unlocking key 430 are both arranged on the upper surface of the mounting seat 20, the buckle hole 321 is arranged on the portion of the buckle 320 exposed from the buckle slot 210, the insert tongue 420 is horizontally inserted into the buckle hole 321 to limit the buckle 320, and when the limit needs to be released, the unlocking key 430 is pulled to drive the insert tongue 420 to exit the buckle hole 321. At this time, since the locking assembly 40 limits the portion of the buckle 320 exposed from the buckle slot 210, it is convenient to directly observe the insertion of the insert tongue 420 into the buckle hole 321 and understand the limit situation. For another example, the locking assembly 40 is similar to the second safety lock structure in the above embodiment, and uses a lever or other pressure plate to be pressed on the surface of the buckle 320 exposed in the buckle slot 210, and directly uses the lever or pressure plate to restrict the buckle 320 from detaching from the buckle slot 210.

[0124] Furthermore, in some embodiments, the belt body 310 may be made of polyester, which is strong and durable. The buckle 320 may be made of plastic or metal.

[0125] Furthermore, in some embodiments, Figures 1 to 4 As shown, the mounting seat 20 is annular, and the buckle slots 210 are distributed on opposite sides of the mounting seat 20 in the radial direction. The two ends of the belt body 310 are connected to the opposite ends of the mounting seat 20, so that the container body 10 can be stably lifted by using the mounting seat 20.

[0126] Furthermore, in some embodiments, the mounting seat 20 is used to be connected to the container body 10. In order to prevent the shoulder strap 30 from being accidentally separated from the container body 10, the mounting seat 20 can be fixedly connected to the container body 10 to ensure the installation stability of the mounting seat 20 and the container body 10, thereby preventing the container body 10 from falling off during the process of being lifted by the shoulder strap 30 due to the mounting seat 20 being detached from the container body 10.

[0127] As an example, Figure 2 and Figure 4 As shown, the mounting seat 20 is annular, the inner ring of the mounting seat 20 is provided with a clamping portion 270, the outer periphery of the container body 10 is provided with a clamping groove 110, and the clamping portion 270 is clamped into the clamping groove 110 to prevent the mounting seat 20 from being separated from the container body 10. During the specific installation, the mounting seat 20 can be sleeved on the container body 10 from the top, and the mounting seat 20 can be pressed vertically downward until the clamping portion 270 is clamped into the clamping groove 110.

[0128] Furthermore, in some embodiments, Figures 1 to 4 As shown, the mounting seat 20 is also provided with an external thread, which is higher than the buckle slot 210 and is used for screwing and connecting with the container cover 60. Compared with the connection between the container cover 60 and the container body 10, the corresponding connection structure is eliminated on the container body 10, the container body 10 is simplified, and the processing is convenient.

[0129] like Figures 1 to 4 As shown, a second aspect of the present invention provides a container, which includes a container body 10 and a shoulder strap assembly as described in any one of the above embodiments, and a mounting seat 20 is mounted on the container body 10 .

[0130] The container provided in the embodiment of this aspect has the shoulder strap assembly of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0131] In some embodiments, the container is a pot or a thermos pot, but is not limited thereto. The container body 10 can be any one of a thermos pot, a cup or a lunch box. Of course, the container body 10 can also be other containers that can hold food.

[0132] In some embodiments, the container further includes a container cover 60 , which can be covered on the container body 10 , and the container cover 60 is screwed together with the mounting seat 20 .

[0133] As an example, Figure 1 and Figure 3 As shown, the container is a lifting pot, the container body 10 is the lifting pot body, the container also includes a lifting pot inner box 720, the lifting pot inner box 720 is detachable and can be placed in the lifting pot body, the container also includes an anti-overflow cover 710, which covers the top opening of the lifting pot body, and the container cover 60 is further covered on top of the anti-overflow cover 710.

[0134] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
