[0023] The present utility model provides a joint structure.

[0024] In the embodiments of the present utility model, as Figures 1 to 5 shown, the joint structure includes a first connecting member 1 and a second connecting member 2 that are hinged to each other, and a locking member 3 for locking the first connecting member 1 and the second connecting member 2. The locking member 3 is movably installed on the first connecting member 1 and can move relative to the first connecting member 1 between a position where it is partially inserted into the second connecting member 2 and a position away from it. By the way that the locking member 3 is partially inserted into the second connecting member 2, the rotation of the second connecting member 2 relative to the first connecting member 1 is restricted, and by the way that the locking member 3 is away from the second connecting member 2, the restriction is released.

[0025] Specifically, the hinged position of the first connecting member 1 and the second connecting member 2 and the locking member 3 are of the same axis or different axes. When they are of the same axis, the locking member 3 can pivot together with the rotation of the first connecting member 1; when they are of different axes, the locking member 3 can be a pin or a plug that is movably inserted into the first connecting member 1, and the pin or the plug can swing together with the rotation of the first connecting member 1.

[0026] Specifically, the first connecting member 1 is provided with a first cavity 11 adapted to the locking member 3, the second connecting member 2 is provided with a second cavity 21 adapted to part of the locking member 3, the locking member 3 is movably provided in the first cavity 11 and can move between a position where the locking member 3 is partially inserted into the second cavity 21 and a position away from the first cavity 11. When the locking member 3 is partially inserted into the second cavity 21, the remaining part of the locking member 3 is still in the first cavity 11, so that the second connecting member 2 cannot rotate relative to the first connecting member 1, thereby achieving the locking of the first connecting member 1 and the second connecting member 2. When the locking member 3 moves in a direction away from the second cavity 21 and completely exits the second cavity 21, the lock can be released. When the locking member 3 is the latch or the plug, the number of the second cavities 21 is one or more, and when it is more than one, the second cavities 21 are spaced apart along the swinging track of the latch or the plug.

[0027] Specifically, when the hinged positions of the locking member 3, the first connecting member 1 and the second connecting member 2 are on the same axis, the locking member 3 is non-circular in shape, such as a polygon, an ellipse, or a gear structure with a plurality of small teeth 31 and at least one large tooth 32 as shown in the figure. It can rotate between the positions where the large teeth 32 are aligned and offset with the corresponding positions of the second cavity 21 as the first connecting member 1 rotates. When aligned, the locking member 3 can be partially inserted into the second cavity 21. When offset, the locking member 3 can be restricted by the large teeth 32 from moving in the direction of partially inserting into the second cavity 21.

[0028] Specifically, in this embodiment, as shown in the figure, the locking member 3 has two large teeth 32 .

[0029] Specifically, a pivot portion 12 is provided at one end of the first connecting member 1, and the locking member 3 is movably installed in the pivot portion 12. A pivot groove 22 is provided at one end of the second connecting member 2 for the pivot portion 12 to extend into. After the pivot portion 12 extends into the pivot groove 22, the hinge pin 4 is inserted to cooperate with the first connecting member 1, the second connecting member 2 and the locking member 3 to be hinged together.

[0030] Specifically, it also includes a top spring 5, and the top spring 5 is used to apply an elastic force to the locking member 3 to move in a direction where the part is partially inserted into the second connecting member 2. Specifically, one end of the top spring 5 elastically abuts against the first connecting member 1, and the other end elastically abuts against the locking member 3, and the elastic force applied by the top spring 5 can make the part of the locking member 3 automatically inserted into the second cavity 21 to realize the automatic locking of the first connecting member 1 and the second connecting member 2.

[0031] Specifically, a button 6 is further provided. The button 6 is movably installed on the second connecting member 2 and can move relative to the second connecting member 2 between a position where the locking member 3 is forced away from the second connecting member 2 and a position away from the locking member 3. In this way, the unlocking operation can be realized by pressing the button 6 from the outside, so that the locking member 3 moves in a direction away from the second connecting member 2 against the elastic force applied by the top spring 5.

[0032] Specifically, a pushing portion 61 for contacting the locking member 3 is provided on one side of the button 6 close to the locking member 3. The pushing portion 61 extends into the second cavity 21 and a barb 62 is formed at the end to prevent the pushing portion 61 from withdrawing from the second cavity 21, thereby preventing the button 6 from detaching from the second connecting member 2. When the hinge joint of the locking member 3 with the first connecting member 1 and the second connecting member 2 is not coaxial, the movement range of the pushing portion 61 cannot exceed the second cavity 21, that is, the pushing portion 61 just withdraws the locking member 3 from the second cavity 21 and then cannot move any further, avoiding the first connecting member 1 and the second connecting member 2 being locked again due to the pushing portion 61. In this embodiment, as shown in the figure, the locking member 3 is in the shape of a gear, and the hinge joint of the locking member 3 with the first connecting member 1 and the second connecting member 2 is coaxial. Both the first cavity 11 and the second cavity 21 are circular grooves with a plurality of convex portions spaced on the peripheral wall. The circular grooves can avoid the pushing portion 61 of the button 6, so that the pushing portion 61 will not limit the rotation of the pivot portion after pushing the locking member 3 away from the second cavity 21.

[0033] Specifically, the pivot joint portion 12 is in the shape of a circular plate for easy rotation.

[0034] Specifically, the second cavity 21 extends in a direction away from the first cavity 11 to penetrate the second connecting member 2 to form an outer opening, and a cover body 7 is fixed to the second connecting member 2 to close the outer opening. Specifically, the cover body 7 is fixed in the second cavity 21 through the hinge pin 4. The cover body 7 is provided with an installation position 71 for accommodating the button 6, and the pushing portion 61 of the button 6 passes through the cover body 7 and then extends into the second cavity 21.

[0035] The present utility model also proposes a door barrier, including a door frame and a joint structure. The door frame is formed by connecting two vertical rods 8 and two cross bars 9. The joint structure is provided on the vertical rod 8 and / or the cross bar 9. The two ends of the vertical rod 8 and / or the cross bar 9 can swing between positions close to each other and away from each other through the joint structure to realize the folding or unfolding of the door frame. For the specific structure of the joint structure, please refer to the above embodiments. Since this door barrier adopts all the technical solutions of all the above embodiments of the joint structure, it has at least all the beneficial effects brought by the technical solutions of the joint structure, and will not be elaborated here one by one.

[0036] Specifically, the free ends of the first connecting member 1 and the second connecting member 2 are provided with insertion holes 100. The vertical rod 8 and / or the horizontal rod 9 are divided into two sections. One end of one section is inserted into the insertion hole 100 of the first connecting member 1 and locked by a bolt, and the end of the other section is inserted into the insertion hole 100 of the second connecting member 2 and locked by a bolt.

[0037] It should be noted that for other structures of the door fence, reference can be made to the prior art, and the specific structural principles thereof will not be elaborated herein.

[0038] In the technical solution of the present utility model, a joint structure is provided on the vertical rod and / or the horizontal rod of the door fence frame. The two ends of the vertical rod and / or the horizontal rod can be driven by the first connecting member and the second connecting member that are hinged to each other through the joint structure to approach or move away from each other, so as to realize the folding or unfolding of the door frame. A locking member is also movably installed on the first connecting member. By partially inserting the locking member into the second connecting member, the relative rotation of the second connecting member with respect to the first connecting member is restricted, thereby restricting the folding of the door frame. By moving the locking member away from the second connecting member, the restriction on the door frame is released. Compared with the traditional one, the door frame of the present utility model has a folding function, and the folded door frame occupies a small space, which is convenient for storage and transportation.

[0039] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
