Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

The first embodiment is as follows: as shown in fig. 1 to 9, the plastic storage box includes a box body 1 and a door panel 2 rotatably connected to the box body 1, wherein a fetching and placing opening 1a is formed in a side wall of the box body 1, and the door panel 2 is located at the fetching and placing opening 1 a; the figures in the description show two door panels 2, which door panels 2 are rotated horizontally, whereby the two door panels 2 are facing apart. The door lock structure of the plastic container includes a lock assembly 3, a rotary rod 4 and a handle 5.

The rotating rod 4 is positioned at the inner side of the door panel 2, and the handle 5 is positioned at the outer side of the door panel 2. Be equipped with shaft hole 2a on the door plant 2, the both ends of bull stick 4 all imbed in shaft hole 2a, bull stick 4 rotates with door plant 2 from this and is connected, and this structure can also improve the bearing capacity of 4 tip of bull stick. The axial lead of the rotating rod 4 is vertically arranged, namely the axial lead of the rotating rod 4 is arranged in parallel with the rotating axial lead of the door panel 2, so that the direction of acting force applied to the handle 5 when the door lock structure is locked and unlocked can be kept consistent with the acting force applied to the rotating door panel 2.

Seted up on door plant 2 and kept away hole 2b, had joint head 5a on the handle 5, seted up joint groove 5b on the joint head 5a, in 4 imbeds joint groove 5b of bull stick, be tight fit between bull stick 4 and the joint head 5a, pulled handle 5 from this, handle 5 just drives bull stick 4 and rotates. The lateral surface of the clamping head part 5a depends on the medial surface of the avoiding hole 2b, so that the bearing capacity of the handle 5 is improved, the load of the handle 5 on the rotating rod 4 is reduced, the rotating stability of the handle 5 is improved, the opening size of the avoiding hole 2b is controlled, the rotating angle of the handle 5 can be limited, and the rotating angle of the rotating rod 4 is controlled. Have lug portion 4a on the bull stick 4, seted up the draw-in groove on the lateral wall of joint groove 5b, in lug portion 4a embedding draw-in groove, guarantee handle 5 and bull stick 4 synchronous rotation from this.

The lock assembly 3 is provided with a locking piece 3a and a bolt piece 3b, the locking piece 3a is fixed on the side wall of the taking and placing port 1a, the bolt piece 3b is fixedly connected with the rotating rod 4, and the bolt piece 3b is eccentrically arranged relative to the axial lead of the rotating rod 4. The attached figures of the specification show that the locking piece 3a and the bolt piece 3b are both in a sheet shape, the locking piece 3a is connected with the side wall of the taking and placing port 1a into a whole, and the bolt piece 3b is connected with the rotating rod 4 into a whole. The number of the lock components 3 is two, and the bolt pieces 3b of the two lock components 3 are correspondingly connected with the two end parts of the rotating rod 4 one by one; the locking pieces 3a of one group of lock assemblies 3 are fixed on the lower side wall of the taking and placing port 1a, and the locking pieces 3a of the other group of lock assemblies 3 are fixed on the upper side wall of the taking and placing port 1 a. The locking pieces 3a in the two groups of door lock structures on the same side wall of the taking and placing opening 1a are connected into a whole, so that the strength of the locking pieces 3a is obviously increased, and the possibility of breakage of the locking pieces 3a is reduced.

When the door panel 2 is in a closed state and the door lock structure is in a locked state, the door panel 2 abuts against the blocking edge part 1b of the taking and placing opening 1a, the handle 5 is in a state close to the door panel 2, and the bolt piece 3b is positioned on the inner side of the locking piece 3a, namely the locking piece 3a is positioned between the bolt piece 3b and the door panel 2, so that the door panel 2 is prevented from rotating outwards; this state is also referred to as the latch piece 3b being in engagement with the lock piece 3 a. When the locking state is required to be switched to the unlocking state, people pull the handle 5 outwards, the handle 5 drives the rotating rod 4 to rotate, the rotating rod 4 drives the two lock tongue pieces 3b to synchronously rotate, and the lock tongue pieces 3b rotate to the left side or the right side of the locking piece 3a, wherein the state is also called that the lock tongue pieces 3b and the locking piece 3a are in a separated state; at this time, the handle 5 is continuously pulled outwards, so that the door rotates outwards to open the door. When the unlocking state needs to be switched to the locking state, people push the handle 5 inwards, the handle 5 drives the rotating rod 4 to rotate, the rotating rod 4 drives the two lock tongue pieces 3b to synchronously rotate, and the lock tongue pieces 3b rotate to the inner sides of the lock tongue pieces 3 a; if the door is in the open state, the door panel 2 is abutted against the edge part 1b, and then the handle 5 is pushed.

As shown in fig. 1 to 9, the plastic storage box is a plastic folding storage box, the box body 1 includes a base 1c, a top cover 1d, a bead positioning ring 1e and four side wall plates 1f rotatably connected to the base 1c, a drawing of the specification shows that one side wall plate 1f is provided with a taking and placing opening 1a, and each side wall plate 1f can be provided with a taking and placing opening 1a according to actual conditions; the door panel 2 is rotatably connected with the side wall plate 1f, and the door panel 2 is connected with the side wall plate 1f through the door lock structure; the lock assembly 3 has a lock member 3a integrally connected to the side wall plate 1 f.

When the side wall plates 1f are in a vertical state relative to the base 1c, the box body 1 is in an unfolded state, the top edges of the four side wall plates 1f are embedded into bead positioning rings 1e, and the bead positioning rings 1e are positioned on the inner side of the top cover 1 d.

Two adjacent side wall plates 1f are connected through a mutual clamping structure, the mutual clamping structure comprises a first clamping groove 1f1 positioned on one side wall plate 1f and a first clamping strip portion 1f2 positioned on the other side wall plate 1f, when one side wall plate 1f rotates outwards, the first clamping strip portion 1f2 can be embedded into the first clamping groove 1f1, and when one side wall plate 1f rotates inwards, the first clamping strip portion 1f2 can be separated from the first clamping groove 1f 1. The side wall of the first card slot 1f1 is provided with a second card strip portion 1f3, the first card strip portion 1f2 is provided with a second card slot 1f4, and when the first card strip portion 1f2 is in a state of being inserted into the first card slot 1f1, the second card strip portion 1f3 is inserted into the second card slot 1f4, so that the possibility that the one side wall plate 1f naturally swings inward is reduced.

Example two: the structure and principle of the present embodiment are substantially the same as those of the first embodiment, and the substantially same parts are not described redundantly, but only different parts are described, and the different parts are: the locking pieces 3a are cylindrical, and the locking pieces 3a in the two groups of door lock structures on the same side wall of the taking and placing opening 1a are not connected together.

Example three: the structure and principle of the present embodiment are substantially the same as those of the first embodiment, and the substantially same parts are not described redundantly, but only different parts are described, and the different parts are: locking piece 3a is the cubic, has seted up the locking groove on locking piece 3a, and spring bolt piece 3b is the column. When the door lock structure is in a locking state, the bolt piece 3b is embedded into the locking groove; when the locking state is switched to the unlocking state, the bolt piece 3b swings and slides out of the locking groove; when the unlocking state is switched to the locking state, the bolt piece 3b swings and slides into the locking groove.
