Abstract
Description
Technical Field
[0001] The utility model relates to a locking structure, and more specifically, to a locking structure for the legs of a folding table. Background Art
[0002] A folding table is a table with a folding function. It is widely used in a variety of indoor and outdoor occasions because it is easy to fold and transport. In order to ensure the firmness of the folding table legs used in the support process, common folding tables usually need to be equipped with various rods, keys, hooks and other structures to lock the table legs in the open state. The structure is relatively complex, the operation steps are more, and it is not convenient when fixing and contact fixing. Utility Model Content
[0003] The utility model aims to provide a folding table leg locking structure which is simple in structure and convenient and quick in solving the above-mentioned deficiencies in the prior art.
[0004] The technical solution of the utility model is achieved as follows: a folding table leg locking structure comprises an upper table leg and a lower table leg, wherein the upper table leg and the lower table leg are hinged via a hinge assembly; a positioning structure is provided between the hinged ends of the upper table leg and the lower table leg, and a locking sleeve for fixing the positioning structure is threadedly connected to the upper table leg or the lower table leg; when the locking sleeve cooperates with the positioning structure, the upper table leg and the lower table leg are in a fixed support state.
[0005] In the above-mentioned folding table leg locking structure, the hinge assembly includes a first hinge seat arranged at the lower side of the upper leg end, a second hinge seat cooperating with the first hinge seat is arranged at the lower leg end, and the first hinge seat and the second hinge seat are connected by a hinge shaft.
[0006] In the above-mentioned locking structure for the legs of a folding table, the positioning structure includes a positioning groove arranged at the end of the upper leg, and a positioning plug corresponding to the positioning groove is provided on the lower leg.
[0007] In the above-mentioned folding table leg locking structure, an inclined yielding guide portion is provided at the front end of the positioning plug block.
[0008] In the above-mentioned locking structure for the legs of a folding table, a threaded section protruding outwards is provided on the outer wall of the upper leg and is connected to the locking sleeve.
[0009] After the utility model adopts the above structure, when the upper table leg and the lower table leg are rotated to the same straight line, it is only necessary to lock the positioning structure by rotating the locking ring through the thread, so that the upper table leg and the lower table leg can be quickly fixed, and to unlock it, it is only necessary to rotate the locking ring, which is simple, convenient and fast to operate. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The present invention will be further described in detail below in conjunction with the embodiments in the accompanying drawings, but this does not constitute any limitation to the present invention.

[0014] In the figure: 1, upper table leg; 2, lower table leg; 3, hinge assembly; 4, positioning structure; 5, locking sleeve; 3a, first hinge seat; 3b, second hinge seat; 3c, hinge axis; 4a, positioning groove; 4b, positioning plug; 4c, yielding guide; 6, threaded section. DETAILED DESCRIPTION
[0015] See also Figure 1-3 As shown, a folding table leg locking structure of the utility model comprises an upper table leg 1 and a lower table leg 2, wherein the upper table leg 1 and the lower table leg 2 are hingedly connected by a hinge assembly 3; a positioning structure 4 is provided between the hinged ends of the upper table leg 1 and the lower table leg 2, and a locking sleeve 5 for fixing the positioning structure 4 is threadedly connected to the upper table leg 1 or the lower table leg 2; when the locking sleeve 5 cooperates with the positioning structure 4, the upper table leg 1 and the lower table leg 2 are in a fixed support state. The locking ring and the positioning structure facilitate the quick fixing of the upper table leg and the lower table leg.
[0016] In this embodiment, the hinge assembly 3 includes a first hinge seat 3a disposed at the lower end of the upper leg 1, a second hinge seat 3b matched with the first hinge seat 3a is disposed at the end of the lower leg 2, and the first hinge seat 3a and the second hinge seat 3b are connected by a hinge shaft 3c. With this structure, when the locking sleeve is rotated into place, its end contacts the hinge seat, which can ensure that the locking sleeve and the positioning structure are accurately matched.
[0017] In this embodiment, preferably, the positioning structure 4 includes a positioning groove 4a provided at the end of the upper table leg 1, and a positioning plug 4b corresponding to the positioning groove 4a is provided on the lower table leg 2.
[0018] Further preferably, the front end of the positioning plug 4b is provided with an inclined guide portion 4c. The inclined guide portion can prevent the end of the positioning plug from pressing against the inner wall of the positioning slot and causing it to get stuck when the positioning plug rotates into the positioning slot.
[0019] In this embodiment, the outer wall of the upper table leg 1 is provided with a threaded section 6 protruding outwards and connected to the locking sleeve 5. The threaded section is protruding outwards and arranged on the outer wall of the upper table leg. When the locking sleeve is detached from the thread, it can slide freely along the upper table leg, which can reduce the setting length of the threaded section and facilitate the installation of the locking sleeve on the upper table leg.
[0020] When in use, the lower table leg and the upper table leg are rotated to the same straight line and the positioning plug is inserted into the positioning groove, and the locking sleeve is rotated along the threaded section until the end portion contacts the first hinge seat to complete the locking.
[0021] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
