Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a lock and a folding trolley case. Background Art

[0002] Folding boxes, also known as turnover boxes and logistics boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries because they can be folded and are easy to use. They take up little space when folded and have a large storage space when unfolded. They are also very suitable for self-driving travel. Many families will also prepare a folding box to facilitate the transportation of a large number of items in life.

[0003] When other boxes or items are placed on top of the folding box, the other boxes or items on top of the box must be removed before the items can be taken or stored. Some items are placed at the bottom of the box. When they need to be taken, all the items on the upper side of the box must be taken out before the items at the bottom of the box can be taken out. At the same time, in order to ensure that the items placed inside will not fly out easily, and to prevent debris from entering the folding box, an openable side door is usually set on the side of the folding box, so that users can take out the items in the folding box at any time.

[0004] For example, Chinese patent CN202321600351.7 discloses a foldable shopping cart, in which a buckle is provided to ensure that the front door panel will not be easily unfolded, so as to ensure a locked state between the front door panel and the box body.

[0005] The prior art still has the following deficiencies:

[0006] 1. Although the structure of the buckle is simple, the buckle itself is small in size but needs to bear a large load for a long time, so it is also easy to be damaged, which reduces the service life of the folding box.

[0007] 2. Some buckle structures can easily fix the door panel, but it is more troublesome to open it. People often need to use more force to pry the door panel or push multiple buckles to open the door panel, which makes the unlocking action not convenient enough. Utility Model Content

[0056] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0057] like Figure 1-Figure 3 A lock as shown, comprising:

[0058] The locking plate 2 has a supporting portion 21 formed thereon, and a supporting inclined surface 23 formed on the supporting portion 21;

[0059] The trigger member 3 has a pressing portion 35 and a pushing portion 31 formed thereon, and a driving inclined surface 33 is formed on the pushing portion 31;

[0060] When the locking plate 2 cooperates with the trigger member 3 , the abutting portion 21 faces the pushing portion 31 , so that the abutting inclined surface 23 and the driving inclined surface 33 can fit each other.

[0061] And from Figure 3 It can be seen that the width of the abutting slope 23 is greater than the width of the driving slope 33 , so when the abutting slope 23 and the driving slope 33 can fit each other, the driving slope 33 can move along the abutting slope 23 .

[0062] By pressing the pressing portion 35 , the trigger member 3 can be moved toward the locking plate 2 , and the driving inclined surface 1 33 can move on the abutting inclined surface 1 23 along the axial direction of the pressing portion 35 , thereby driving the locking plate 2 to move.

[0063] like Figure 1-Figure 3 As shown, the locking plate 2 is further formed with a second abutting portion 22, and a second abutting slope 24 is formed on the second abutting portion 22, and the inclination direction of the second abutting slope 24 is the same as the inclination direction of the first abutting slope 23. Therefore, when the trigger member 3 is pushed toward the locking plate 2, it can be ensured that the direction of the component force received by the locking plate 2 is the same, thereby ensuring that the locking plate 2 can move along the designed direction.

[0064] Because the inclination direction of the second abutting slope 24 is different from that of the first abutting slope 23 , the trigger member 3 will not exert force components in two different directions on the locking plate 2 , thereby affecting the moving route of the locking plate 2 .

[0065] The trigger member 3 is also formed with an avoidance hole 36 , and a side wall of the avoidance hole 36 is formed as a second pushing portion 32 . The second pushing portion 32 is also formed with a second driving slope 34 , and the inclination direction of the second driving slope 34 is the same as that of the first driving slope 33 .

[0066] When the first abutting slope 23 and the first driving slope 33 are in contact with each other, the second abutting slope 24 and the second driving slope 34 are also in contact with each other, and the second abutting portion 22 can extend into the avoidance hole 36 .

[0067] like Figure 1-Figure 4 As shown, the technical solution also includes a fixed cover 4, and the locking plate 2 and the trigger member 3 are partially arranged in the fixed cover 4.

[0068] When the fixing cover 4 is fixed on other surfaces, a mounting cavity 41 is formed between the fixing cover 4 and the surface, which can facilitate the mounting of the locking plate 2 and the trigger member 3 on the surface.

[0069] At the same time, the fixing cover 4 can also limit the moving direction of the locking plate 2, so that the locking plate 2 can only move along the designed direction.

[0070] like Figure 1-Figure 7 As shown, a reset spring 1 6 and a reset spring 2 7 are arranged in the installation cavity 41. The reset spring 1 6 is used to drive the locking plate 2 to reset and be in the locking position, and the reset spring 2 7 is used to drive the trigger member 3 to reset and be in the pressing position.

[0071] The locking position mentioned herein refers to the position where the locking plate 2 is in which the locking plate 2 can be locked. The pressing position mentioned herein refers to the position where the triggering member 3 is farthest from the locking plate 2 when the locking plate 2 and the triggering member 3 are arranged in the mounting cavity 41. Pressing the pressing portion 35 at this position can make the locking plate 2 have the maximum stroke to ensure that the locking plate 2 will move out of the locking position.

[0072] An abutting plane 45 is formed in the installation cavity 41 for one end of the return spring 6 to abut against.

[0073] The locking plate 2 is provided with a reset column 28, and the reset spring 16 can be sleeved on the outside of the reset column 28 to fix the position of the reset spring 16. When the locking plate 2 is arranged in the installation cavity 41, the two ends of the reset spring 16 face the side wall of the locking plate 2 and the abutment plane 45 respectively.

[0074] A fixing column 37 is formed on the inner side of the pressing portion 35 , and the return spring 2 7 is sleeved on the fixing column 37 , so that two ends of the return spring 2 7 can respectively abut against the locking plate 2 and the trigger member 3 .

[0075] Specific as Figure 4 As shown, a plurality of limiting posts 42 are formed on the fixed cover 4, and a plurality of limiting holes 25 are formed on the locking plate 2, and the limiting posts 42 can be placed in the limiting holes 25. In the present technical solution, the limiting holes 25 are strip-shaped holes, and the width of the limiting posts 42 matches the width of the limiting holes 25, so that the locking plate 2 can only move along the length direction of the limiting holes 25 through the cooperation between the limiting holes 25 and the limiting posts 42.

[0076] Specific as Figure 1-Figure 6 As shown, a limiting column 3 46 is formed on the fixed cover 4, and a limiting hole 3 20 is formed on the locking plate 2. The limiting column 3 46 can be placed in the limiting hole 3 20;

[0077] The inner recess of the limiting column 3 46 is formed with an abutment groove 47. When the locking plate 2 and the trigger member 3 are connected, the fixing column 37 can partially extend into the abutment groove 47, so that one end of the reset spring 2 7 abuts against the abutment groove 47 and fixes the position of the reset spring 2 7. The abutment groove 47 can also prevent one end of the reset spring 2 7 from swinging.

[0078] like Figure 1-Figure 7 The foldable suitcase shown includes a box body 1, which includes a panel 11 and a folding plate 18. The panel 11 and the folding plate 18 constitute the side wall of the box body 1, and an openable cover 16 is arranged above the panel 11 and the folding plate 18.

[0079] The panel 11 is provided with an access opening 15, and a door panel 5 is provided at the access opening 15. When the cover panel 16 is inconvenient to open, or when it is necessary to take out items at the bottom of the box body 1, the items can be taken out from the inside of the box body 1 through the access opening 15 after the door panel 5 is opened.

[0080] Also included is a lock as described above;

[0081] The fixing cover 4 is detachably disposed on the panel 11 . When the fixing cover 4 is connected to the panel 11 , a mounting cavity 41 is formed between the fixing cover 4 and the panel 11 .

[0082] The locking plate 2 and the trigger member 3 are arranged in the mounting cavity 41 .

[0083] like Figure 1-Figure 7 As shown, the fixed cover 4 is arranged on the inner side of the panel 11, and a through hole 13 is opened on the panel 11. The through hole 13 is connected with the installation cavity 41, and the pressing part 35 can extend out of the through hole 13, so that the user can press the pressing part 35 from the outside of the box body 1 to contact the locked state of the door panel 5 and open the door panel.

[0084] like Figure 1-Figure 7 The side wall of the installation cavity 41 is provided with a lock beam hole 44, and the locking plate 2 is formed with a lock beam 26, and the lock beam 26 can extend out of the lock beam hole 44;

[0085] When the pressing portion 35 is pressed, the lock beam 26 is retracted from the lock beam hole 44 into the installation cavity 41, so that the door panel 5 can be opened;

[0086] The door panel 5 is formed with a lock groove 52. When the locking plate 2 is in the locked position, the lock beam 26 can be placed in the lock groove 52 to keep the door panel 5 in the locked state.

[0087] One end of the door panel 5 is hinged on the panel 11, and the other end of the door panel 5 is formed with a locking block 51, and a locking groove 52 is formed on the locking block 51;

[0088] The end of the locking block 51 is formed with a push inclined surface 53, and the lower end of the locking beam 26 is formed with abutting inclined surface 3 27;

[0089] The panel 11 is provided with a second through hole 14 , through which the locking block 51 can pass, so that the locking groove 52 enters the interior of the box body 1 , making it easier for the locking beam 26 to be inserted into the locking groove 52 .

[0090] like Figure 1-Figure 7 The trigger member 3 is provided with a positioning hole 38, and the panel 11 is provided with a connecting column 12, the diameter of which matches the positioning hole 38, so that the trigger member 3 can be sleeved on the connecting column 12. The cooperation between the connecting column 12 and the positioning hole 38 ensures that the trigger member 3 moves along the connecting column 12 without deviation, thereby ensuring the stable working state of the lock.

[0091] The middle recess of the limiting column 1 42 is formed with a connecting groove 43, so that the connecting column 12 can pass through the positioning hole 38 and then be inserted into the connecting groove 43. Thereby, the relative state between the positioning locking plate 2 and the trigger member 3 can also be started.

[0092] Furthermore, a second limiting column 17 is formed on the panel 11 , and a second limiting hole 29 is opened on the locking plate 2 . When the locking plate 2 and the trigger member 3 are arranged in the mounting cavity 17 , the end of the second limiting column 17 can be movably inserted into the second limiting hole 29 .

[0093] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
