[0067] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] See also Figures 1 to 3 , a hanging lock mechanism 20 provided by an embodiment of the present invention comprises a hanging seat 100, a hanging column 200 and an ejection assembly 300, wherein the hanging column 200 is slidably arranged on the hanging seat 100 along its own axial direction so as to be switchable between an extended position and a retracted position; the ejection assembly 300 is provided with an ejection end and a slidable operating end 332, the ejection end is used to abut against the hanging column 200, and the operating end 332 can be operated to enable the ejection assembly 300 to store force. When the hanging column 200 is released from restriction, the ejection assembly 300 uses its ejection end to eject the hanging column 200 from at least one of the retracted position and the extended position to the other position of the two.

[0069] Among them, the hanging column 200 is ejected from at least one of the retracted position and the extended position to the other position of the two, including the following three application embodiments: in the first possible application embodiment, the hanging column 200 is ejected from the retracted position to the extended position to achieve connection with the external structure; in the second application embodiment, the hanging column 200 is ejected from the extended position to the retracted position to achieve separation from the external structure. In the third application embodiment, the hanging column 200 is ejected from the retracted position to the extended position to achieve connection with the external structure, and the hanging column 200 is ejected from the extended position to the retracted position to achieve separation from the external structure. For the convenience of explanation, this application is mainly described by taking the third application embodiment as an example.

[0070] In specific applications, when the hanging lock mechanism 20 needs to be connected to an external structure, the staff operates the ejection assembly 300 to elastically store force. For example, the ejection assembly 300 is provided with a slidable operating end 332, and the staff pushes the operating end 332 to slide so that the ejection assembly 300 can store force. When the lifting column 200 is released from restriction, the ejection assembly 300 uses its ejection end to release the previously stored force to the lifting column 200, thereby hitting the lifting column 200 to slide toward the outside of the lifting seat 100, and the lifting column 200 slides from the retracted position to the extended position, thereby achieving connection with the external structure. Similarly, when the hanging lock mechanism 20 needs to be separated from the external structure, the staff operates the ejection assembly 300 through the operating end 332 to elastically store force. When the lifting column 200 is released from the restriction, the ejection assembly 300 uses its ejection end to release the previously stored force to the lifting column 200, thereby hitting the lifting column 200 to slide toward the inner side of the lifting seat 100, and the lifting column 200 slides from the extended position to the retracted position, thereby achieving separation from the external structure.

[0071] As can be seen from the above, after the ejection assembly 300 completes the accumulation of force through the operating end 332, the ejection end of the ejection assembly 300 ejects the hanging column 200 to slide when the restriction on the hanging column 200 is released. After the ejection end is separated from the hanging column 200, the hanging column 200 can also use its inertia force to maintain the previous movement, so that the hanging column 200 can slide a sufficiently long distance to satisfy the hanging column 200 sliding from the retracted position to the extended position, or from the extended position to the retracted position. After testing, the staff only needs the operating end 332 of the ejection assembly 300 to slide about 5mm, and the hanging column 200 can slide about 25mm. It can be seen from this that, through the setting of the ejection assembly 300, the staff of the present application only needs to operate the operating end 332 of the elastic assembly to move a small distance to complete the displacement of the hanging column 200 over a large distance, thereby effectively solving the problem of limited operating space of the hanging column 200, thereby improving the user experience of the staff.

[0072] It should be noted that when the hanging column 200 does not need to slide, the ejection assembly 300 is not in a state of storing force. Only when the hanging column 200 needs to slide, the staff will operate the ejection assembly 300 to store force. Such a setting effectively avoids the elastic parts of the ejection assembly 300 being in a large compression state for a long time, thereby ensuring that the ejection assembly 300 has a good ejection effect for a long time.

[0073] In addition, if in the above-mentioned third application embodiment, the stored force of the ejection assembly 300 is not only used to push the lifting column 200 to eject from the retracted position to the extended position, but also used to push the lifting grab to eject from the extended position to the retracted position. It can be seen that the ejection assembly 300 is more flexible in application.

[0074] In order to realize that the ejection assembly 300 can push the hanging column 200 to eject from the retracted position to the extended position, in a possible embodiment, refer to Figure 3 and Figure 4 The ejection assembly 300 includes a first ejection member 310, a force storage operating member 330 and a first elastic member 340, wherein the first ejection member 310 is provided with a first ejection end, and the first ejection end is used to resist the hanging column 200 in the extending direction of the hanging column 200; the force storage operating member 330 is provided with an operating end 332, and the force storage operating member 330 is slidably arranged on the hanging seat 100 and is located on one side of the hanging column 200; one end of the first elastic member 340 is connected to the force storage operating member 330, and the other end is connected to the first ejection member 310, for making the first ejection end resist the hanging column 200; wherein the force storage operating member 330 can be operated to move away from the first ejection member 310 so that the first elastic member 340 can be force stored.

[0075] Specifically, refer to Figure 5 When the hanging lock mechanism 20 needs to be connected to an external structure, the staff pushes the force storage operating member 330 to move in the extension direction of the hanging column 200 through the operating end 332, and the first ejection end abuts against the hanging column 200 in the extension direction of the hanging column 200, and the hanging column 200 is in a restricted state. Therefore, the force storage operating member 330 pulls the first elastic member 340 to lengthen during the sliding, so that the first elastic member 340 obtains elastic force storage. When the hanging column 200 is released from the restriction, the hanging column 200 correspondingly releases the abutting force on the first ejection member 310. At this time, the first elastic member 340 acts on the hanging column 200 in the direction in which the first ejection member 310 extends toward the hanging column 200. Under the impact of the first ejection member 310, the hanging column 200 is ejected from the retracted position to the extended position.

[0076] In order to realize that the ejection assembly 300 can push the hanging column 200 to eject from the extended position to the retracted position, in a possible embodiment, refer to Figure 3 and Figure 4 The ejection assembly 300 includes a second ejection member 320, a force storage operating member 330 and a first elastic member 340, wherein the second ejection member 320 is provided with a second ejection end, and the second ejection end is used to resist the hanging column 200 in the contraction direction of the hanging column 200; the force storage operating member 330 is provided with an operating end 332, and the force storage operating member 330 is slidably arranged on the hanging seat 100 and is located on one side of the hanging column 200; one end of the first elastic member 340 is connected to the force storage operating member 330, and the other end is connected to the second ejection member 320, for making the second ejection end resist the hanging column 200; wherein the force storage operating member 330 can be operated to move away from the second ejection member 320 so that the first elastic member 340 can be charged.

[0077] Specifically, refer to Figure 6 When the hanging lock mechanism 20 needs to be separated from the external structure, the staff pushes the force storage operating member 330 to move in the contraction direction of the hanging column 200 through the operating end 332, and the second ejection end resists the hanging column 200 in the contraction direction of the hanging column 200, and the hanging column 200 is in a restricted state. Therefore, the force storage operating member 330 pulls the first elastic member 340 to lengthen during the sliding, so that the first elastic member 340 obtains elastic force storage. When the hanging column 200 is released from the restriction, the hanging column 200 correspondingly releases the resisting force on the second ejection member 320. At this time, the first elastic member 340 acts on the hanging column 200 in the direction of the second ejection member 320 contracting toward the hanging column 200. Under the impact of the second ejection member 320, the hanging column 200 is ejected from the extended position to the contracted position.

[0078] In order to realize that the ejection assembly 300 can push the hanging column 200 to eject from the retracted position to the extended position, and also to eject from the extended position to the retracted position, in a possible embodiment, refer to Figure 3 and Figure 4The ejection assembly 300 includes a first ejection member 310, a second ejection member 320, a force storage operating member 330 and a first elastic member 340, wherein the first ejection member 310 is provided with a first ejection end, and the first ejection end is used to abut against the hanging column 200 in the extension direction of the hanging column 200; the second ejection member 320 is provided with a second ejection end, and the second ejection end is used to abut against the hanging column 200 in the tail direction of the hanging column 200; the force storage operating member 330 is provided with an operating end 332, and the force storage operating member 330 is provided with an operating end 333. 0 is slidably disposed on the hanging seat 100 and is located between the first ejection member 310 and the second ejection member 320; one end of the first elastic member 340 is connected to the first ejection member 310, and the other end is connected to the second ejection member 320, and the first elastic member 340 is used to make one of the first ejection end and the second ejection end abut against the hanging column 200, wherein the force storage operating member 330 can be operated to move away from the first ejection member 310 or the second ejection member 320, so that the first elastic member 340 is force stored.

[0079] In specific applications, also refer to Figure 5 When the hanging lock mechanism 20 needs to be connected to an external structure, the staff pushes the force storage operating member 330 to move toward the extension direction of the hanging column 200 through the operating end 332, and the force storage operating member 330 pushes the second ejection member 320 to move toward the extension direction of the hanging column 200 at the same time, and the first ejection end is against the hanging column 200 in the extension direction of the hanging column 200, and the hanging column 200 is in a restricted state. Therefore, when the force storage operating member 330 slides, the first elastic member 340 is pulled longer through the second ejection member 320, so that the first elastic member 340 is elastically stored. When the restriction on the hanging column 200 is released, the hanging column 200 releases the resistance force on the first ejection member 310 accordingly. At this time, the first elastic member 340 acts on the hanging column 200 in the direction in which the first ejection member 310 extends toward the hanging column 200. Under the impact of the first ejection member 310, the hanging column 200 is ejected from the retracted position to the extended position.

[0080] Also refer to Figure 6When the hanging lock mechanism 20 needs to be separated from the external structure, the staff pushes the force storage operating member 330 to move in the contraction direction of the hanging column 200 through the operating end 332, and the force storage operating member 330 pushes the first ejection member 310 to move in the extension direction of the hanging column 200 at the same time, and the second ejection end is against the hanging column 200 in the contraction direction of the hanging column 200, and the hanging column 200 is in a restricted state. Therefore, when the force storage operating member 330 slides, the first elastic member 340 is pulled longer by the first ejection member 310, so that the first elastic member 340 is elastically stored. When the restriction on the hanging column 200 is released, the hanging column 200 releases the resistance force on the second ejection member 320 accordingly. At this time, the first elastic member 340 acts on the hanging column 200 in the direction of the second ejection member 320 contracting toward the hanging column 200. Under the impact of the second ejection member 320, the hanging column 200 is ejected from the extended position to the contracted position.

[0081] In some embodiments, reference Figure 3 and Figure 4 The hanging seat 100 includes a guide bottom plate 110 and two guide side plates 120, wherein the two guide side plates 120 are connected to the opposite edge portions of the guide bottom plate 110 and are located on the same side of the guide bottom plate 110, and the two guide side plates 120 are arranged opposite to each other, and a guide channel 130 is formed between the two. The two guide side plates 120 are provided with guide bosses 121 on the opposite sides, the hanging column 200 is slidably connected to the guide channel 130, and is located between the guide bosses 121 and the guide bottom plate 110, and the force storage operating member 330 is slidably arranged on the side of the guide bosses 121 away from the guide bottom plate 110.

[0082] Among them, also refer to Figure 5 and Figure 6 The first ejection member 310 is L-shaped and slidably disposed in the guide channel 130. One side of the first ejection member 310 is located at one end of the force storage operating member 330 and is used to abut against the hanging column 200, and the other side is located at the side of the force storage operating member 330 away from the guide boss 121. Similarly, the second ejection member 320 is L-shaped and slidably disposed in the guide channel 130. One side of the second ejection member is located at the other end of the force storage operating member 330 and is used to abut against the hanging column 200, and the other side is located at the side of the force storage operating member 330 away from the guide boss 121. The first elastic member 340 can be a tension spring. The first elastic member 340 is located at the side of the force storage operating member 330 away from the guide boss 121. One end of the first elastic member 340 is hooked on the other side of the first ejection member 310, and the other end is hooked on the other side of the second ejection member 320.

[0083] It is understandable that the hanging seat 100 adopts the above-mentioned structural form, the overall structure of the hanging seat 100 is relatively simple, and the hanging column 200 and the ejection assembly 300 can be assembled and connected to the hanging seat 100 in a relatively compact manner. Moreover, in specific applications, the hanging seat 100 simultaneously has the function of positioning and guiding the force storage operating member 330, the first ejection member 310 and the second ejection member 320, so that the ejection assembly 300 can stably store force and apply force outward to realize the ejection of the hanging column 200. For example, when the hanging column 200 is released from restriction, the first ejection member 310 or the second ejection assembly 300 can stably act on the hanging column 200 along the guide channel 130 under the action of the first elastic member 340, so that the hanging column 200 slides between the retracted position and the extended position.

[0084] Furthermore, refer to Figure 5 and Figure 6 The hanging lock mechanism 20 also includes a limit pin 220, and the two ends of the limit pin 220 are respectively set as a first limit end 221 and a second limit end 222, wherein the limit pin 220 is arranged in the hanging column 200 along the cross section of the hanging column 200, the first limit end 221 is exposed on one side of the hanging column 200, and the second limit end 222 is exposed on the other side of the hanging column 200. At the same time, the guide bottom plate 110 is provided with a first limit groove 111 along its length direction, and the first limit end 221 is slidably arranged in the first limit groove 111, thereby, the first limit groove 111 restricts the first limit end 221 to make the hanging column 200 slide within a set range. Specifically, when the first limit end 221 abuts against the rear end of the first limit groove 111, the hanging column 200 is in a retracted position; when the first limit end 221 abuts against the front end of the first limit groove 111, the hanging column 200 is in an extended position. Meanwhile, the second limiting end portion 222 is located between the two guide bosses 121 and between the first ejection member 310 and the second ejection member 320 , and is used for abutting against the ejection end of the first ejection member 310 or the second ejection member 320 .

[0085] In specific applications, refer to Figure 5If the hanging column 200 needs to be slid from the retracted position to the extended position, at this time, the first limiting end 221 is located at the rear end of the first limiting groove 111, and the second limiting end 222 is located near the first ejection member 310. The staff pushes the force storage operating member 330 to move in the extension direction of the hanging column 200, and the force storage operating member 330 pulls one end of the first elastic member 340 to move forward through the second ejection member 320. The first ejection member 310 abuts against the side of the second limiting end 222, thereby limiting the forward movement of the other end of the first elastic member 340, thereby the first elastic member 340 is stretched to store force. If the lifting column 200 is released from the restriction, the first ejection member 310 slides forward to the end of the force storage operating member 330 under the action of the first elastic member 340, and the first ejection member 310 acts on the lifting column 200 through the second limiting end 222, and the lifting column 200 and the limiting pin 220 slide forward synchronously until the lifting column 200 slides from the retracted position to the extended position, and the second limiting end 222 slides to a position close to the second ejection member 320.

[0086] Reference Figure 6 If the hanging column 200 needs to be slid back from the extended position to the retracted position, at this time, the first limit end 221 is located at the front end of the first limit slot 111, and the second limit end 222 is located near the second ejection member 320. The staff pushes the force storage operating member 330 to move in the retracting direction of the hanging column 200, and the force storage operating member 330 pulls one end of the second elastic member 420 to move backward through the first ejection member 310. The second ejection member 320 abuts against the side of the second limit end 222, thereby limiting the forward movement of the other end of the first elastic member 340, thereby the first elastic member 340 is stretched to store force. If the lifting column 200 is released from the restriction, the second ejection member 320 slides backward to the end of the force storage operating member 330 under the action of the first elastic member 340, and the second ejection member 320 acts on the lifting column 200 through the second limiting end 222, and the lifting column 200 and the limiting pin 220 slide backward synchronously until the lifting column 200 slides from the extended position to the retracted position, and the second limiting end 222 slides to a position close to the first ejection member 310.

[0087] In some embodiments, reference Figure 3 and Figure 4 The hanging lock mechanism 20 also includes a locking assembly 400, which is arranged on the guide side plate 120 and is used to keep the hanging column 200 in one of the retracted position and the extended position; of course, other methods can also be used to limit the hanging column 200 so that the hanging column 200 is kept in the retracted position or the extended position, for example, the control of the position of the hanging column 200.

[0088] The locking assembly 400 is used to keep the hanging column 200 in one of the retracted position and the extended position, including the following two application embodiments: In the first application embodiment, only one locking assembly 400 can be provided, and when the hanging column 200 is in the retracted position, the locking assembly 400 limits the hanging column 200 so that the hanging column 200 is kept in the retracted position; or, when the hanging column 200 is in the extended position, the locking assembly 400 limits the hanging column 200 so that the hanging column 200 is kept in the extended position. In the second application embodiment, two locking assemblies 400 can be provided, wherein, when the hanging column 200 is in the retracted position, one locking assembly 400 limits the hanging column 200 so that the hanging column 200 is kept in the retracted position; and, when the hanging column 200 is in the extended position, the other locking assembly 400 limits the hanging column 200 so that the hanging column 200 is kept in the extended position. The present application is described with two locking assemblies 400 , but is not limited to only two locking assemblies 400 .

[0089] Furthermore, when releasing the restriction of the locking assembly 400 on the hanging column 200, the staff may directly operate the locking assembly 400 to release the restriction of the locking assembly 400 on the hanging column 200. Other methods may also be used to release the restriction of the locking assembly 400 on the hanging column 200, which will be described in detail later.

[0090] During the specific working process, if the first elastic member 340 has a sufficiently large elastic force, the locking assembly 400 releases the restriction on the hanging column 200, and the hanging column 200 is ejected from the retracted position to the extended position under the action of the first elastic member 340, or the hanging column 200 is ejected from the extended position to the retracted position under the action of the first elastic member 340.

[0091] In a specific embodiment, referring to Figure 3 and Figure 4 There are two locking assemblies 400, which are respectively located on opposite sides of the hanging column 200, that is, one locking assembly 400 is set on one guide side plate 120, and the locking assembly 400 can be used to keep the hanging column 200 in the retracted position; the other locking assembly 400 is set on the other guide side plate 120, and the locking assembly 400 is used to keep the hanging column 200 in the extended position. It can be understood that the two locking assemblies 400 are respectively set on the two guide side plates 120. In this way, the two locking assemblies 400 will not interfere with each other when used, which facilitates the installation design of the two locking assemblies 400.

[0092] In order to unlock the locking assembly 400, in some embodiments, refer to Figure 3 , Figure 4 ,and Figure 7The force storage operating member 330 is configured to act on the locking assembly 400 during sliding, so that the locking assembly 400 releases the restriction on the hanging column 200 .

[0093] Specifically, if the staff pushes the force storage operating member 330 to move toward the extension direction of the hanging column 200 through the operating end 332, when the first elastic member 340 is stretched to a set length, the force storage operating member 330 just pushes the locking assembly 400 to release the restriction on the hanging column 200. At this time, the first elastic member 340 acts on the hanging column 200 through the first ejection member 310, and the hanging column 200 is ejected from the retracted position to the extended position. If the staff pushes the force storage operating member 330 to move toward the retracted direction of the hanging column 200 through the operating end 332, when the first elastic member 340 is stretched to a set length, the force storage operating member 330 just pushes the locking assembly 400 to release the restriction on the hanging column 200. At this time, the first elastic member 340 acts on the hanging column 200 through the second ejection member 320, and the hanging column 200 is ejected from the extended position to the retracted position.

[0094] It is understandable that when the staff slides the force storage operating member 330, the force storage operating member 330 automatically pushes the locking assembly 400 to release the restriction on the hanging column 200 during the sliding process, and the staff does not need to operate the locking assembly 400 to release the restriction on the hanging column 200. It can be seen from the above that the force storage operating member 330 and the locking assembly 400 are arranged in coordination, and the hanging lock mechanism 20 is more convenient to operate when in use.

[0095] In a specific embodiment, referring to Figure 3 , Figure 4 and Figure 7 The locking assembly 400 includes a locking member 410 and a second elastic member 420, wherein the locking member 410 is movably connected to the sling seat 100 so as to be switchable between a first position and a second position. For example, the locking member 410 is slidably disposed on the guide side plate 120, or is rotatably disposed on the guide side plate 120, or is movably connected to the guide side plate 120 in other ways. The second elastic member 420 is connected to the guide side plate 120 and the locking member 410, and the second elastic member 420 is used to keep the locking member 410 in the first position.

[0096] When the hanging column 200 is in the retracted position, the locking member 410 of the corresponding locking assembly 400 is in the first position, and the locking member 410 is locked with the hanging column 200 to keep the hanging column 200 in the retracted position; if the locking member 410 is in the second position, the locking member 410 and the hanging column 200 are separated, and the hanging column 200 can be ejected from the retracted position to the extended position under the action of the first elastic member 340. When the hanging column 200 is in the extended position, the locking member 410 of another locking assembly 400 is in the first position, and the locking member 410 is locked with the hanging column 200 to keep the hanging column 200 in the extended position; if the locking member 410 is in the second position, the locking member 410 and the hanging column 200 are separated, and the hanging column 200 can be ejected from the extended position to the retracted position under the action of the first elastic member 340.

[0097] Furthermore, the two sides of the force storage operating member 330 close to the two guide side plates 120 are respectively provided with guide slopes 331, and the two guide slopes 331 are inclined in opposite directions. When the force storage operating member 330 slides toward the extension direction of the hanging column 200, the guide slope 331 on the corresponding side of the force storage operating member 330 acts on the corresponding locking member 410. When the first elastic member 340 completes the force storage, the guide slope 331 just pushes the locking member 410 to switch from the first position to the second position, thereby releasing the restriction of the locking member 410 on the hanging column 200, thereby, the hanging column 200 can be ejected from the retracted position to the extended position under the action of the first elastic member 340; when the force storage operating member 330 slides toward the retracted direction of the hanging column 200, the guide slope 331 on the other side of the force storage operating member 330 acts on the corresponding locking member 410. When the first elastic member 340 completes the force accumulation, the guide slope 331 just pushes the locking member 410 to switch from the first position to the second position, thereby releasing the restriction of the locking member 410 on the hanging column 200. As a result, the hanging column 200 can be ejected from the extended position to the retracted position under the action of the first elastic member 340.

[0098] In some embodiments, reference Figure 3 , Figure 4 and Figure 7, the inner sides of the two guide side plates 120 are provided with positioning slots 122, which are roughly triangular in shape and extend into the sliding space of the hanging column 200 and the force storage operating member 330, and partially extend into the guide boss 121. The locking member 410 is an elastic sheet-like body, and is vertically inserted into the positioning slot 122 relative to the hanging seat 100. One end of the locking member 410 is inserted and fixed in a corner position of the positioning slot 122, and the other end is arranged near one side of the positioning slot 122, and can move in the positioning slot 122 with the previous edge as the fixed end. Because the positioning slot 122 partially extends to the guide boss 121, the movable edge of the locking member 410 can be simultaneously located in the sliding space of the hanging column 200 and the force storage operating member 330, so as to be able to be clamped with the hanging column 200 and slide along the guide inclined surface 331.

[0099] Specifically, when the locking member 410 is in the first position, the movable edge portion of the locking member 410 is located in the sliding space of the hanging column 200, thereby maintaining the hanging column 200 in the retracted position or the extended position; at the same time, the movable edge portion of the locking member 410 is located in the sliding space of the force storage operating member 330, and the force storage operating member 330 can also act on the locking member 410 when sliding along the guide channel 130, so that the locking member 410 is deformed from the first position to the second position. At this time, the locking member 410 is hidden on the inner side of the guide side plate 120, thereby releasing the restriction on the guide column 200.

[0100] It is understandable that the locking member 410 is connected to the guide side plate 120 by plugging. With this arrangement, not only is the structure of the locking member 410 simpler, but more importantly, the connection method between the locking member 410 and the guide side plate 120 is simpler, thereby facilitating the installation and disassembly of the guide side plate 120.

[0101] In some embodiments, reference Figure 3 and Figure 4The hanging lock mechanism 20 further includes a sliding cover plate 500 and a top cover 600, wherein the sliding cover plate 500 is arranged on the side of the force storage operating member 330 away from the guide bottom plate 110 and is engaged with each other, thereby the sliding cover plate 500 holds the first elastic member 340 on the side of the force storage operating member 330 away from the guide bottom plate 110. The operating end 332 is a positioning protrusion arranged on the outside of the force storage operating member 330, and a positioning slot is arranged on the side of the sliding cover plate 500 close to the force storage operating member 330, and the positioning protrusion is plugged and connected to the positioning slot to realize the engagement between the sliding cover plate 500 and the force storage operating member 330, thereby, the staff can push the force storage operating member 330 to slide synchronously through the sliding cover plate 500. At the same time, a sliding protrusion 510 is arranged on the outside of the sliding cover plate 500. The top cover 600 is connected to the two guide side plates 120 and is arranged in close contact with the side of the sliding cover plate 500 away from the force storage operating member 330, so that the top cover 600 is used to keep the sliding cover plate 500 in close contact with the force storage operating member 330. The top cover 600 is provided with a second limiting groove 610 along the sliding direction of the hanging column 200, and the sliding protrusion 510 is slidably arranged in the second limiting groove 610.

[0102] As can be seen from the above, the sliding cover plate 500 and the top cover 600 are arranged in cooperation, which conveniently and effectively stably assembles the ejection assembly 300 in the guide channel 130 of the hanging lock seat, thereby the overall structure of the hanging lock mechanism 20 is simple. At the same time, the top cover 600 limits the sliding range of the sliding protrusion 510 of the sliding cover plate 500, so that the force storage operating member 330 slides within the effective range.

[0103] In some embodiments, reference Figure 8 and Fig. 9 The outer side of the hanging lock mechanism 20 is provided with a shell assembly 700, and the shell assembly 700 includes a first shell 710 and a second shell 720 that are spliced ​​together, and the hanging column 200 is inserted through the through hole between the first shell 710 and the second shell 720. The hanging lock mechanism 20 also includes a movable handle 800, both ends of which are rotatably arranged on the shell assembly 700, and are transmission-connected with the sliding end 510, thereby being transmission-connected with the operating end 332, and the rotation center axis of the movable handle 800 is vertically arranged with the center axis of the hanging column 200. Among them, when the movable handle 800 is rotated and operated, it drives the power storage operating member 330 to slide relative to the hanging seat 100, so that the ejection assembly 300 is power stored. For example, the movable handle 800 is transmission-connected with the sliding protrusion 510 through an eccentric structure, thereby being transmission-connected with the operating end 332.

[0104] It is understandable that the movable handle 800 itself can be used as a handle, and the staff can conveniently carry the box body through the movable handle 800. At the same time, the staff can drive the force storage operating member 330 to slide through the movable handle 800, so that the ejection assembly 300 can be charged, thereby ejecting the hanging column 200 from the telescopic position to the extended position, or ejecting the hanging column 200 from the retracted position to the extended position (refer to Figure 8 and Fig.10 ).

[0105] It should be noted that when the rotational motion of the movable handle 800 is switched to linear motion, the movable handle 800 can only be switched to long-distance linear motion unless the size of the movable handle 800 is large, so as to meet the long-distance pushing of the hanging column 200. In the present application scheme, through the setting of the ejection assembly 300, the movable handle 800 does not need to be set to a large size, and the ejection assembly 300 can also be used to achieve a long-distance pushing of the hanging column 200 during rotation, so as to meet the sliding of the hanging column 200 from the retracted position to the extended position, or from the extended position to the retracted position.

[0106] Further, when the movable handle 800 rotates to the extending direction of the hanging column 200, the hanging column 200 is in the retracted position (refer to Figure 8 When the movable handle 800 rotates to the back side of the hanging lock mechanism 20, the hanging column 200 is in the extended position (refer to Fig.10 ). Among them, refer to Fig.10 An elastic clip 730 is provided at a position of the second shell 720 near the transition part of the movable handle 800, and the movable handle 800 is provided with two slots at the position of the transition part, so that when the movable handle 800 is rotated to the extending direction of the hanging column 200, the elastic clip 730 is connected to one of the slots to keep the movable handle 800 in this position; when the movable handle 800 is rotated to the back side of the hanging lock mechanism 20, the elastic clip 730 is connected to the other slot to keep the movable handle 800 in this position.

[0107] It is understandable that when the movable handle 800 rotates to the extension direction of the hanging column 200, the staff can conveniently lift the box body through the movable handle 800, so as to facilitate the transportation of the box body; wherein, the hanging column 200 is in the retracted position, so that the hanging column 200 does not affect the staff's convenient grasping of the movable handle 800. Accordingly, the movable handle 800 does not need to be set to a larger size, so that the staff can grasp the movable handle 800, thereby effectively avoiding the need to set the hanging lock mechanism 20 to a larger size.

[0108] In some embodiments, reference Figures 10 to 12, the movable handle is connected to the sliding protrusion 510 through the transmission assembly 900. Specifically, the transmission assembly 900 also includes a first connecting shaft 910, a second connecting shaft 920, a first connecting member 930 and a second connecting member 940, wherein the first connecting shaft 910 is rotatably connected to the housing assembly 700, and the end of the movable handle 800 is connected to the first connecting shaft 910, so as to realize the rotatable connection between the movable handle 800 and the hanging seat 100. The first connecting member 930 is fixedly connected to the first connecting shaft 910, and the second connecting member 940 is rotatably connected to the first connecting member 930, and the rotation center axis of the first connecting member 930 and the second connecting member 940 is eccentrically arranged with the rotation center axis of the first connecting shaft 910. The second connecting shaft 920 is connected to the power storage operating member 330 and the second connecting member 940, and is rotatably connected to at least one of them. For example, the second connecting shaft 920 is rotatably inserted into the sliding protrusion 510, thereby being rotatably connected to the force storage operating member 330, the second connecting member 940 is rotatably connected or fixedly connected to the second connecting shaft 920, and the rotation center axis of the first connecting member 930 and the second connecting member 940 is eccentrically arranged with the rotation center axis of the second connecting shaft 920.

[0109] In specific applications, when the movable handle 800 rotates, the movable handle 800 drives the first connecting shaft 910 to rotate, and the first connecting shaft 910 drives the second connecting shaft 920 and the sliding protrusion 510 to slide synchronously along the second limiting groove 610 through the first connecting member 930 and the second connecting member 940, thereby driving the power storage operating member 330 to slide along the hanging seat 100, thereby realizing the power storage of the ejection assembly 300. Among them, a rotatable second connecting member 940 is arranged between the second connecting shaft 920 and the first connecting member 930, and the second connecting member 940 effectively avoids the motion interference between the circumferential motion of the first connecting member 930 and the sliding motion of the second connecting shaft 920, and the present application scheme can be implemented. Of course, if the sliding protrusion 510 is provided with a strip through groove along its protruding direction, the first connecting member 930 can be directly rotatably connected with the second connecting shaft 920, and the second connecting member 940 does not need to be arranged, and the rotational motion of the movable handle 800 can be switched to the sliding motion of the second connecting shaft 920.

[0110] The present application also discloses a display device, referring to Figure 3 and Fig.13 , including at least two spliced ​​display units 10 and the above-mentioned hanging lock mechanism 20, wherein the hanging lock mechanism 20 is set on one of the adjacent display units 10 and connected to the other one.

[0111] It is understandable that when the display device adopts the above-mentioned hanging lock mechanism 20, when adjacent display units 10 are installed or removed, the staff can manipulate the operating end 332 to slide over a short distance, thereby using the ejection assembly 300 to achieve long-distance movement of the hanging column 200 over a large distance, thereby facilitating the installation or removal of adjacent display units 10.

[0112] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
