Description

Technical Field

[0001] The present invention belongs to the technical field of locks, and in particular relates to a lock structure and a suitcase. Background Art

[0002] Suitcases are used to carry luggage when traveling long distances, such as for travel and business trips. They have a large capacity, are convenient for carrying belongings, and can be dragged, effectively reducing the burden of carrying belongings. Currently, suitcases primarily consist of a case and a lock structure, wherein the case comprises an upper case and a lower case. One side of the upper case and the lower case are hinged, and the other side of the upper case and the lower case are locked by a lock structure, thereby completing the opening and closing of the upper case and the lower case.

[0003] However, when too many items are placed in an existing suitcase, the suitcase body will be squeezed, causing the suitcase to bulge outward to a certain extent, thereby changing the position of the lock head and the lock buckle in the lock structure. At this time, the lock head and the lock buckle cannot be kept in the same position, making it difficult for the lock head to be buckled into the lock buckle, resulting in the suitcase being unable to be locked. Summary of the Invention

[0004] In response to the above-mentioned defects or improvement needs of the prior art, the present invention provides a lock structure and a suitcase, the purpose of which is to ensure that the lock head is accurately inserted into the lock buckle when the suitcase is deformed, and at the same time achieve locking between the upper and lower suitcases.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a lock structure, comprising a lock head assembly and a lock catch assembly; The lock assembly includes a housing, a lock, and two pressing heads. One side of the housing is rotatably arranged on the lower box, and the rotation axis of the housing extends along a first direction. The two pressing heads are spaced apart and arranged on the housing along a second direction perpendicular to the first direction. The lock is slidably arranged on the other side of the housing along the first direction. The lock assembly includes a lock seat and a lock, the lock seat is used to be installed on the upper box body, the lock can be slidably arranged on the lock seat, the sliding track of the lock is arc-shaped and perpendicular to the first direction, the lock has a crimping plane and a strip groove, the two pressing heads are used to contact the crimping plane after being pressed, the strip groove is used to accommodate the lock head, and the inner wall of the strip groove on the side away from the lock seat is a limiting plane, the limiting plane is parallel to the crimping plane and spaced apart, and the limiting plane is used to limit the lock head after contacting the lock head.

[0006] Optionally, the lock assembly further includes a push knob and an elastic member, the push knob being slidably arranged on the shell along the second direction, the push knob having a protrusion, the protrusion having a first inclined surface on the side facing the lock head, the first inclined surface being used to squeeze the lock head to slide, and an elastic member being sandwiched between the lock head and the shell.

[0007] Optionally, one side of the push knob has a plurality of slides arranged in parallel and at intervals, and the housing has a plurality of sliding grooves arranged in parallel and at intervals, and each of the slides can be slidably inserted into the corresponding sliding groove.

[0008] Optionally, the lock head has a second inclined surface, and the second inclined surface is used to squeeze the lock buckle so that the lock head compresses the elastic member.

[0009] Optionally, the shell includes a mounting base and a main body, the mounting base is used to be installed on the lower box body, rubber sleeves are inserted on both sides of the mounting base, and mounting shafts are fixedly inserted on both sides of the main body, and one end of the mounting shaft can be rotatably inserted in the corresponding rubber sleeve.

[0010] Optionally, the main body includes an upper shell and a lower shell, the mounting shaft is fixedly inserted on both sides of the upper shell, the lock head can be slidably arranged on the lower shell, and the lower shell can be detachably mounted on the upper shell to form a accommodating cavity, and the lock head can extend out of the accommodating cavity or retract into the accommodating cavity.

[0011] Optionally, the lock head has a matching plane, and the matching plane is used to fit with the limiting plane.

[0012] Optionally, the lock seat has a T-shaped slot, the lock buckle has a T-shaped block, and the T-shaped block can be slidably inserted into the T-shaped slot.

[0013] Optionally, the lock seat has a boss, which is used to be inserted into a zipper hole of a zipper used to connect the upper box body and the lower box body, and the boss is located between the shell and the lock seat.

[0014] In a second aspect, the present invention provides a suitcase, comprising a lock structure as described in the first aspect.

[0015] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0016] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art: In a lock structure provided by an embodiment of the present invention, before locking the box, the shell is first installed on the lower box and the lock seat is installed on the upper box. When the box is not deformed, to close the upper and lower boxes: rotate the shell so that the other side of the shell rotates to the lock seat. When it is rotated into place, the two pressure heads are pressed on the crimping plane and limit the lock buckle. The lock head is slid and inserted into the strip groove and contacts the limit plane. At this time, due to the contact limit between the lock head and the limit plane, the upper and lower boxes cannot be rotated open, and finally the upper and lower boxes are locked.

[0017] When the housing deforms outwardly, the pressing head simultaneously presses the lock catch as the housing rotates toward the lock seat, causing the lock catch to move along an arc-shaped trajectory on the lock seat. Ultimately, the two pressing heads simultaneously contact the pressing plane, achieving leveling of the lock catch relative to the two pressing heads, thereby achieving adaptive adjustment of the lock catch. This also allows the bottom surfaces of the two pressing heads to be parallel to the limiting plane, ensuring that the corresponding lock head on the housing can subsequently be inserted into the strip groove. Finally, after moving, the lock head extends and contacts the limiting plane, preventing the upper and lower housings from rotating open. Furthermore, in other cases of outward deformation (for example, when the upper and lower housings simultaneously deform outward, increasing the distance between the rotating end of the housing and the lock seat), even if the positions of the two pressing heads on the pressing plane vary, and the corresponding position of the lock head relative to the strip groove in the second direction differs, the locking head can still be smoothly inserted into the strip groove and contacted with the limiting plane because the limiting plane is parallel to the pressing plane and spaced apart.

[0018] That is to say, the lock structure provided by the present invention can still ensure that the lock head is accurately inserted into the lock buckle when the box body is deformed, and at the same time achieve locking between the upper box body and the lower box body.

Example:

[0026] Figure 1 is a structural diagram of a lock structure provided by an embodiment of the present invention, Figure 2 This is an exploded view of a lock structure provided by an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of the lock without an upper shell provided by an embodiment of the present invention, combined with Figure 1-Figure 3 As shown, the lock structure includes a lock head assembly 1 and a lock catch assembly 2.

[0027] The lock head assembly 1 includes a housing 11, a lock head 12 and two pressing heads 13. One side of the housing 11 is used to be rotatably arranged on the lower box 100, and the rotation axis of the housing 11 extends along a first direction (for example, the X-axis direction). The two pressing heads 13 are arranged on the housing 11 at intervals along a second direction (for example, the Y-axis direction). The second direction is perpendicular to the first direction. The lock head 12 is slidably arranged on the other side of the housing 11 along the first direction. An elastic member 15 is sandwiched between the lock head 12 and the housing 11.

[0028] Figure 4 FIG. 1 is a structural diagram of a lock assembly provided by an embodiment of the present invention. Figure 4As shown, the lock assembly 2 includes a lock seat 21 and a lock catch 22. The lock seat 21 is used to be installed on the upper box body 200. The lock catch 22 is slidably arranged on the lock seat 21. The sliding trajectory of the lock catch 22 is arc-shaped and perpendicular to the first direction. The lock catch 22 has a crimping plane 221 and a strip groove 222. The two pressing heads 13 are both used for pressing (that is, the pressing head 13 can make the lock catch 22 swing along an arc shape for adaptive calibration during the pressing process) and then contact the crimping plane 221. The strip groove 222 is used to accommodate the lock head 12, and the inner wall of the strip groove 222 away from the lock seat 21 is a limiting plane 2221. The limiting plane 2221 is parallel to the crimping plane 221 and spaced apart. The limiting plane 2221 is used to limit the lock head 12 after contacting it.

[0029] Regarding a lock structure provided by an embodiment of the present invention, before locking the box, the shell 11 is first installed on the lower box 100 and the lock seat 21 is installed on the upper box 200. When the box is not deformed, to close the upper box 200 and the lower box 100: rotate the shell 11 so that the other side of the shell 11 rotates to the lock seat 21. When it is rotated into place, the two pressure heads 13 are pressed on the pressing plane 221 and limit the lock buckle 22. The sliding lock head 12 can be inserted into the strip groove 222 and contact the limiting plane 2221. At this time, due to the contact limitation of the lock head 12 and the limiting plane 2221 (the lock head needs to make a circular motion relative to the hinge axis of the box during the box opening process), the upper box 200 and the lower box 100 cannot be rotated to open, and finally the upper box 200 and the lower box 100 are locked.

[0030] When the box is deformed outwardly and the housing 11 rotates to the lock seat 21, the pressing head 13 will simultaneously press the lock catch 22, causing the lock catch 22 to move along an arc-shaped trajectory on the lock seat 21. Ultimately, the two pressing heads 13 simultaneously contact the pressing surface 221, achieving leveling of the lock catch 22 relative to the two pressing heads 13, thereby achieving adaptive adjustment of the lock catch 22 and making the bottom surfaces of the two pressing heads 13 parallel to the limiting surface 2221, ensuring that the corresponding lock head 12 on the subsequent housing 11 can be precisely inserted into the strip groove 222. Finally, after moving, the lock head 12 just extends out and contacts the limiting surface 2221, making it impossible for the upper box 200 and the lower box 100 to rotate and open. Moreover, in other cases of convex deformation (for example, the upper and lower box bodies are deformed outward synchronously as a whole, thereby increasing the distance between the rotating end of the shell 11 and the lock seat 21), even if the positions of the two pressing heads 13 on the crimping plane 221 change, and the corresponding positions of the lock head 12 corresponding to the strip groove 222 in the second direction are different, since the limiting plane 2221 is parallel to the crimping plane 221 and spaced apart, the lock head 12 can still be smoothly inserted into the strip groove 222 and contact-limited with the limiting plane 2221.

[0031] In other words, the lock structure provided by the present invention can ensure that the lock head 12 is accurately inserted into the lock buckle 22 when the box body is deformed, and at the same time achieve locking between the upper box body 200 and the lower box body 100.

[0032] In addition, when the box needs to be unlocked, the lock head 12 is driven backward so that the lock head 12 is disengaged from the strip groove 222, and the shell 11 can be freely rotated, finally realizing the opening between the upper box 200 and the lower box 100.

[0033] For example, the lock head 12 can be locked by the combination lock 3, that is, the combination lock 3 can realize the locking and unlocking of the lock head 12 by sliding. Therefore, when the password entered into the combination lock 3 is correct, the combination lock 3 unlocks the lock head 12, and the lock head 12 can be driven to slide by an external force; when the password entered into the combination lock 3 is incorrect, the combination lock 3 remains locked on the lock head 12, and the lock head 12 cannot move, so that the lock head 12 cannot be disengaged from the strip groove 222.

[0034] Figure 5 This is a first view of the push button provided by an embodiment of the present invention. Figure 6 This is a second view of the push button provided by the embodiment of the present invention, combined with Figure 5 and Figure 6 As shown, the lock assembly 1 also includes a push knob 14 and an elastic member 15. The push knob 14 is slidably arranged on the shell 11 along the second direction. The push knob 14 has a protrusion 141. The protrusion 141 has a first inclined surface 1411 on the side facing the lock head 12. The first inclined surface 1411 is used to squeeze the lock head 12 to slide. An elastic member 15 is sandwiched between the lock head 12 and the shell 11.

[0035] Specifically, when the push knob 14 is pushed, the push knob 14 will drive the protrusion 141 to move, and the first inclined surface 1411 of the protrusion 141 will squeeze the lock head 12, so that the lock head 12 overcomes the elastic force of the elastic member 15 and retreats, thereby conveniently controlling the retreat of the lock head 12 before the lock head 12 is inserted into the strip groove 222, and conveniently unlocking the lock head 12 after the lock head 12 is inserted into the strip groove 222.

[0036] Exemplarily, the elastic member 15 may be a spring.

[0037] For example, when the housing 11 is rotated onto the lock seat 21, the force acting on the push knob 14 is released, and the lock head 12 can be automatically inserted into the strip groove 222 under the action of the elastic member 15, and the push knob 14 can be reset to the initial position. In addition, the number of protrusions 141, lock heads 12, and lock catches 22 can all be two, and the corresponding number of press heads 13 is four, divided into two groups, thereby achieving multi-point locking and ensuring stability after locking. Among them, the two lock catches 22 are arranged in parallel and spaced apart, and the two lock catches 22 are located between the two protrusions 141, and the multiple press heads 13 can be located on the push knob 14.

[0038] Furthermore, one side of the push knob 14 has a plurality of slides 142 arranged in parallel and spaced apart, and the shell 11 has a plurality of slide grooves arranged in parallel and spaced apart. Each slide 142 can be slidably inserted into the corresponding slide groove, so that the push knob 14 can be accurately guided by the insertion and cooperation of the slide 142 and the slide groove.

[0039] In one implementation of the present invention, Figure 7 : is a schematic diagram of the structure of the lock provided by an embodiment of the present invention, such as Figure 7 As shown, the lock head 12 has a second inclined surface 121 , and the second inclined surface 121 is used to squeeze the lock buckle 22 so that the lock head 12 compresses the elastic member 15 .

[0040] In the above embodiment, during the rotation of the shell 11, the lock head 12 automatically retreats due to the squeezing contact between the second inclined surface 121 and the lock buckle 22, ensuring that the lock head 12 can automatically retreat during the rotation of the shell 11, and automatically insert into the strip groove 222 under the action of the elastic member 15 after the shell 11 is rotated into place.

[0041] In addition, the lock head 12 has a matching plane 122 , which is used to fit with the limiting plane 2221 .

[0042] It is easy to understand that when the lock head 12 is inserted into the strip groove 222, the matching plane 122 is exactly in contact with the limiting plane 2221, and the locking of the lock head 12 and the lock buckle 22 is more reliable, thereby making the locking of the upper box body 200 and the lower box body 100 more reliable.

[0043] In this embodiment, the shell 11 includes a mounting base 111 and a main body 112. The mounting base 111 is used to be installed on the lower box body 100. Rubber sleeves 1111 are inserted on both sides of the mounting base 111. Mounting shafts 1112 (i.e., the rotating shafts of the shell 11) are fixedly inserted on both sides of the main body 112. One end of the mounting shaft 1112 is rotatably inserted in the corresponding rubber sleeve 1111.

[0044] In the above embodiment, the mounting base 111 serves to connect the lower case 100, facilitating the rotational installation of the body 112. The rubber sleeve 1111 can increase the resistance to the rotation of the body 112, achieving a hovering effect or slow descent, thereby preventing the housing 11 from swinging freely and causing damage when the housing 11 is not locked to the lock buckle 22.

[0045] It should be noted that, in other embodiments of the present invention, the mounting shaft 1112 may also be directly rotatably inserted into the mounting seat 111 (ie, the rubber sleeve 1111 is not provided).

[0046] Furthermore, the body 112 includes an upper shell 1121 and a lower shell 1122. Mounting shafts 1112 are fixedly mounted on both sides of the upper shell 1121. The lock head 12 is slidably arranged on the lower shell 1122, and the lower shell 1122 is detachably mounted on the upper shell 1121 to form an accommodating cavity. The lock head 12 can extend into the accommodating cavity or retract into the accommodating cavity. When the lock head 12 is retracted into the accommodating cavity, the lock head 12 can be protected.

[0047] Exemplarily, the elastic member 15 is located in the receiving groove, and the push button 14 is located on the upper shell 1121 .

[0048] Continue to see Figure 3 The lock base 21 has a T-shaped slot 211, and the lock catch 22 has a T-shaped block 223. The T-shaped block 223 is slidably inserted into the T-shaped slot 211. The cooperation between the T-shaped block 223 and the T-shaped slot 211 can prevent the lock catch 22 from sliding upward from the lock base 21. The T-shaped slot 211 extends along an arc.

[0049] Exemplarily, the lock seat 21 is a U-shaped structure as a whole, and a lock seat bottom shell 213 is also provided on the lock seat 21. The lock seat bottom shell 213 has a blocking block, which can be inserted into the opening of the lock seat 21 to prevent the lock buckle 22 from detaching from the left and right ends of the T-slot 211.

[0050] In this embodiment, the lock base 21 has a boss 212 , which is used to be inserted into a zipper hole of a zipper used to connect the upper box body 200 and the lower box body 100 , and the boss 212 is located between the housing 11 and the lock base 21 .

[0051] It is easy to understand that this lock structure can be used in a suitcase with a zipper. When the upper and lower cases 200 and 100 are connected and locked by the zipper, to prevent the zipper from accidentally sliding and unlocking, the zipper is placed on the boss 212 to prevent accidental zipper slippage. In addition, the zipper is located between the housing 11 and the lock base 21, thus providing shielding and protection for the zipper (i.e., the zipper can only be removed from the boss 212 when the housing 11 is opened), preventing the zipper from being unlocked by non-users when the case is locked.

[0052] Exemplarily, the boss 212 is located between the two lock buckles 22 .

[0054] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
