Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of folding storage box, especially a side plate locking mechanism for storage box and folding storage box. BACKGROUND

[0002] The folding storage box is a box for placing articles during travel, which can be folded when not in use, and is provided with a pull rod on the side and a tire at the bottom, so that it can be dragged. The folding is to turn up the bottom plate and make the two side plates face inward to achieve the folding of the box body. During use, the side plates are unfolded and the bottom plate is turned down. In order to ensure the stability of the unfolded side plates, a locking mechanism is needed on the side plates to keep the side plates in the same plane.

[0003] For example, Chinese utility model patent 202020241297.1 uses the sliding cavity on the lock block to cooperate with the first guide rail and the second guide rail on the first plate body and the second plate body to lock the first plate body and the second plate body and keep them in the same plane.

[0004] This locking form has the following defects: the folding storage box is a plastic part, so the first plate body, the second plate body and the lock block are all plastic parts, and the thickness of the lock block is limited, so the strength is poor, and the stability of the first plate body and the second plate body is poor during use.

[0005] Therefore, it is urgent to design a locking mechanism that can improve the locking stability between the first plate body and the second plate body. UTILITY MODEL CONTENTS

[0006] The utility model provides a side plate locking mechanism for storage box and folding storage box to solve the above technical problems, which can keep the first plate body and the second plate body of the side plate in the same plane and has high stability.

[0007] This utility model discloses a side panel locking mechanism for a storage box. The side panel of the storage box includes a first plate and a second plate. The side edges of the first plate and the second plate are rotatably connected by a pin. An inner groove is provided on the upper side wall of the first plate near the second plate. A locking block is provided on the side wall of the second plate corresponding to the inner groove. When the first plate and the second plate rotate to the same plane, the locking block is located inside the inner groove. A vertical locking hole is provided on the first plate at the upper end of the inner groove, and a vertically sliding push-button is provided on the first plate at the upper end of the inner groove. A push rod is installed inside the hole, and the push buckle is connected to the push rod. The push buckle drives the push rod to move inside the lock hole. A vertical guide hole is provided on the lock block corresponding to the lock hole. A compression spring is provided at the lower end of the guide hole. A lock rod is provided inside the guide hole. In its natural state, the upper end of the lock rod is exposed outside the lock block and inserted into the lock hole. A guide slope is provided on the side wall of the first plate at the upper end of the lock rod or the upper end of the inner groove. The guide slope is used to push the lock rod into the guide hole when the first plate and the second plate rotate to the same plane, so that the lock block can be completely inserted into the inner groove.

[0008] During the process of the first plate and the second plate rotating to the same plane, the first plate on the side where the locking block enters the inner groove is provided with a guide slope. The guide slope extends downward from the side near the second plate to be flush with the upper wall of the inner groove.

[0009] The top of the locking bar has an arc-shaped structure.

[0010] The lock hole passes through the first plate above the inner groove. The push buckle is U-shaped and inserted into the first plate above the inner groove. The upper end of the push rod is fixedly connected to the push buckle. When the push buckle moves to the lowest position, the lower end of the push rod is flush with the lower end of the lock hole.

[0011] The guide hole is a stepped hole with a smaller top and a larger bottom. A compression spring is installed inside the stepped hole. The lower end of the locking rod is provided with an outwardly protruding limiting ring. The upper end of the compression spring abuts against the limiting ring. The diameter of the limiting ring is larger than the diameter of the upper end of the stepped hole.

[0012] The lock hole passes through the lock block, and a plug is threadedly connected to the lower end of the lock hole. The lower end of the compression spring abuts against the plug, and the plug is used to adjust the position of the lowest end of the compression spring.

[0013] A folding storage box, wherein the two opposite side panels are fitted with the aforementioned side panel locking mechanism, which is used to restrict the first and second panels of the side panels to be in the same plane.

[0014] The present invention provides a side panel locking mechanism for a storage box and a storage box in which a pressing buckle is provided on the side panel to release the locking rod from the locking hole, thereby making the limiting and stabilizing between the first plate and the second plate, and making the operation simple.

[0021] In order to further illustrate the technical means and effects taken by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0022] Example 1:

[0023] As Figures 1-5 The utility model discloses a kind of side plate locking mechanism for storage box, the side plate of storage box includes first plate body 1 and second plate body 2, the side of first plate body 1 is connected with the side of second plate body 2 by pin shaft 3 rotation, and the upper end side wall of first plate body 1 is provided with inner groove 5 in the side of second plate body 2, locking block 6 is provided on the side wall of second plate body 2 corresponding with inner groove 5, when first plate body 1 and second plate body 2 rotate to the same plane, locking block 6 is located in the inside of inner groove 5;Locking hole 11 in the vertical direction of first plate body 1 on the upper end of inner groove 5, press button 4 that is vertically slid is provided on the first plate body 1 on the upper end of inner groove 5, push rod 12 is provided in locking hole 11, the press button 4 is connected with push rod 12, push rod 12 is moved in locking hole 11 by press button 4;Guiding hole 8 in the vertical direction is provided on locking block 6 corresponding with locking hole 11, compression spring 9 is provided in the lower end of guiding hole 8, locking rod 10 is provided in guiding hole 8, locking rod 10 upper end is exposed outside locking block 6 in natural state, and is inserted in locking hole 11;Guiding slope 7 is provided on the side wall of first plate body 1 on the upper end of inner groove 5, the guiding slope 7 is used to push locking rod 10 into guiding hole 8 in the process that first plate body 1, second plate body 2 rotate to the same plane, so that locking block 6 can enter inner groove 5 completely.

[0024] The storage box generally comprises a bottom plate, four side plates, and a top cover, bottom tires, a pull rod, etc. The overall structure of the storage box is known in the art and will not be described here. In order to fold the storage box, two opposite side plates are foldable. Therefore, the structure of the two opposite side plates comprises a first plate body 1 and a second plate body 2, which are connected by a pin shaft 3 to achieve folding. The connection between the first plate body 1 and the second plate body 2 is provided with protrusions alternately, and the pin shaft 3 is arranged on the protrusions, so as to realize the butt joint. The side plate locking mechanism is arranged at the upper end of the first plate body 1 and the second plate body 2.

[0025] An inner groove 5 is arranged on the first plate body 1, and a protruding locking block 6 is arranged on the second plate body 2 corresponding to the inner groove 5. When the first plate body 1 and the second plate body 2 are rotated around the pin shaft 3 to the same plane, the locking block 6 is embedded in the inner groove 5. A guide hole 8 is arranged on the locking block 6, a locking hole 11 is arranged on the first plate body 1 above the inner groove 5, and the locking hole 11 and the guide hole 8 are butt jointed in the vertical direction when the locking block 6 is embedded in the inner groove 5. A locking rod 10 is arranged in the guide hole 8, and a compression spring 9 is arranged in the guide hole 8 below the locking rod 10. Therefore, in the natural state, the compression spring 9 pushes the locking rod 10 upward, so that the upper end of the locking rod 10 is exposed outside the guide hole 8, that is, the end of the locking rod 10 is exposed outside the locking block 6. The design of the guide slope 7 on the first plate body 1 above the inner groove 5 is that, in the process of rotating the first plate body 1 and the second plate body 2 to the same plane, the upper end of the locking rod 10 first contacts the guide slope 7, and the guide slope 7 gradually descends from outside to inside. Therefore, the locking rod 10 is pressed inward when the first plate body 1 and the second plate body 2 are rotated to the same plane, and the force acting on the locking rod 10 by the guide slope 7 generates a downward component force, which pushes the locking rod 10 into the guide hole 8, so that the locking block 6 can be embedded in the inner groove 5. After the locking block 6 is embedded in the inner groove 5, the guide hole 8 is butt jointed with the locking hole 11, and at this time, the first plate body 1 and the guide slope 7 are separated from the locking rod 10. Therefore, the locking rod 10 enters the locking hole 11 under the action of the compression spring 9, thereby locking the locking block 6 and the first plate body 1, limiting the relative position of the first plate body 1 and the second plate body 2, and keeping them in the same plane. Since the pressing buckle 4 arranged vertically on the first plate body 1 above the inner groove 5 is connected with the push rod 12 in the locking hole 11, the push rod 12 and the pressing buckle 4 are pushed upward after the locking rod 10 enters the locking hole 11. When unlocking, only a downward pressure needs to be applied to the pressing buckle 4 to make the pressing buckle 4 move downward. In this process, the push rod 12 moves downward in the locking hole 11, pushing the locking rod 10 downward to completely move out of the locking hole 11. At this time, the first plate body 1 and the second plate body 2 are rotated, and the locking block 6 is removed from the inner groove 5, thereby achieving the release of the first plate body 1 and the second plate body 2.

[0026] In this way, the automatic locking can be realized when the first plate body 1 and the second plate body 2 are unfolded, and the stability is high after locking, and when being folded, only the press buckle 4 needs to be pushed downward, and the operation is simple and convenient. Since the press buckle 4 is located at the top of the side plate, the operation is convenient.

[0027] During the rotation of the first plate body 1 and the second plate body 2 to the same plane, the first plate body 1 on one side of the inner groove 5 where the lock block 6 enters is provided with a guide slope 7, which extends downward from the side close to the second plate body 2 to be flush with the upper wall of the inner groove 5. The guide slope 7 is arranged on the first plate body 1 above the entrance of the inner groove 5 where the lock block 6 enters, so that the lock rod 10 will contact first, and during the process that the lock block 6 enters the inner groove 5, the guide slope 7 always applies a downward force on the lock rod 10 to press the lock rod 10 downward until the end of the lock rod 10 contacts the upper surface of the inner groove 5, at which time the lock block 6 continues to rotate in the inner groove 5 without interference. Until the lock block 6 is in place inside the inner groove 5, the lock hole 11 is connected to the guide hole 8, that is, the lock rod 10 enters the lock hole 11. Since the lock rod 10 rotates around the pin shaft 3 during the rotation of the first plate body 1 and the second plate body 2, the guide slope 7 can have an arc structure, that is, cover the running track of the lock rod 10.

[0028] The top of the lock rod 10 is an arc surface structure. The top of the lock rod 10 is an arc surface structure, preferably a hemispherical structure, that is, the hemispherical structure of the top of the lock rod 10 contacts the guide arc surface, so that the sliding between the two is smoother and the stability is high.

[0029] The lock hole 11 penetrates the first plate body 1 above the inner groove 5, the press buckle 4 is a U-shaped structure inserted into the first plate body 1 above the inner groove 5, the upper end of the push rod 12 is fixedly connected with the press buckle 4, and when the press buckle 4 moves to the lowermost position, the lower end of the push rod 12 is flush with the lower end of the lock hole 11. The first plate body 1 above the inner groove 5 can be recessed inward and outward, so that after the press buckle 4 is inserted into the first plate body 1 above the inner groove 5, the outer surface of the press buckle 4 can be flush with the outer surface of the entire first plate body 1, and the appearance is better. Moreover, the push rod 12 will be connected to the middle part of the press buckle 4, and during the process that the press buckle 4 is pressed downward, the push rod 12 can be stably driven to move downward, and the operation reliability is high. The maximum position of the downward movement of the press buckle 4 is just to make the lower end of the push rod 12 consistent with the lower end of the lock hole 11, that is, the lower end of the push rod 12 is flush with the upper surface of the inner groove 5, so that the push rod 12 can completely exit the lock hole 11, and the push rod 12 will not enter the guide hole 8, so that the lock block 6 and the first plate body 1 are completely released, and the rotation of the two does not interfere with each other, and the operation is convenient.

[0030] The guide hole 8 is a stepped hole with a small upper part and a large lower part, and a compression spring 9 is arranged in the stepped hole. The lower end of the lock rod 10 is provided with an outwardly protruding limiting ring 13, the upper end of the compression spring 9 abuts against the limiting ring 13, and the diameter of the limiting ring 13 is larger than the diameter of the upper end of the stepped hole. The stepped hole is used as the guide hole 8, which can effectively limit the maximum distance of upward movement of the lock rod 10, and avoid the lock rod 10 from falling out of the guide hole 8 during transportation of the folded storage box. In addition, the compression spring 9 at the bottom extrudes the lock rod 10 upward, and in the natural state, the upper end of the lock rod 10 is exposed outside the lock block 6. At this time, the compression spring 9 is still in a small compression state, that is, the compression spring 9 applies a certain pushing force to the lock rod 10, so as to keep the lock rod 10 stable.

[0031] The lock hole 11 penetrates through the lock block 6, and the lower end of the lock hole 11 is threadedly connected with a plug 14, the lower end of the compression spring 9 abuts against the plug 14, and the plug 14 is used to adjust the position of the lowermost end of the compression spring 9.

[0032] The plug 14 is threadedly connected at the bottom of the guide hole 8, and adjusting the position of the plug 14 can adjust the compression state of the compression spring 9, so as to change the pushing force applied by the compression spring 9 to the lock rod 10. The pushing force applied by the compression spring 9 to the lock rod 10 can be adjusted according to actual conditions, so as to improve the use performance.
