Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 7, a novel door horizontal bar buckle comprises a large pipe sleeve 2, a housing 3 sleeved outside the large pipe sleeve 2 and capable of moving axially relative to the large pipe sleeve 2 under an external force, and a small pipe sleeve 5 disposed inside the large pipe sleeve 2.

A clamping structure is arranged between the shell 3 and the small pipe sleeve 5, the shell 3 enables the clamping structure to be in a locking state under a free state so as to limit the small pipe sleeve 5 to rotate, and the shell 3 can enable the clamping structure to be in an unlocking state through axial movement after being stressed so as to enable the small pipe sleeve 5 to have a degree of freedom of rotation relative to the large pipe sleeve 2.

Specifically, the clamping structure comprises a latch 4 installed inside the housing 3 and a second tooth 501 arranged at the outer diameter of the small pipe sleeve 5, wherein the inner side surface of the latch 4 is provided with a first tooth 401, the tooth socket length direction of the first tooth 401 and the second tooth 501 is parallel to the axial direction of the small pipe sleeve 5, and thus when the latch 4 moves axially, the first tooth 401 and the second tooth 501 can be engaged or disengaged to realize quick fit.

More specifically, the front end inner wall position of shell 3 is equipped with a plurality of latch installation positions 302, and latch 4 fixed mounting is on latch installation position 302, and in this embodiment, latch installation position 302 is equipped with two, and winds the central axis evenly distributed of shell 3, and the quantity of latch 4 is the same with latch installation position 302, and the root of latch installation position 302 has the mounting hole 304 that link up in shell 3, and mounting hole 304 department mounting screw or plastics nail are fixed in order to realize the installation of latch 4.

The outer wall of the small pipe sleeve 5 is provided with a clamping groove 203 with an L-shaped structure, the latch 4 is slidably mounted in the clamping groove 203, namely when the small pipe sleeve is actually used, the latch 4 can move in the clamping groove 203 by sliding the outer shell 3, when the latch 4 moves to a position far away from the middle pipe 1, the first tooth 401 is meshed with the second tooth 501, and at the moment, the locking state is a locking state which is a conventional state in the use process of a horizontal bar, meanwhile, the spring 7 applies acting force to the outer shell 3 to ensure that the latch 4 is always arranged at the position, so that the rotation of the small pipe sleeve 5 is limited, and the purpose of limiting the rotation of the telescopic pipe 6 is achieved; when latch 4 moves to the position that is close to middle pipe 1, first tooth 401 becomes the disengagement state from the engagement state with second tooth 501, is in the unblock state promptly to can rotate the telescopic link, adjust its flexible length, for the convenience of liberating both hands in the adjustment process, can rotate shell 3 and latch 4, make latch 4 remove to the rear end root position of draw-in groove 203.

Specifically, a spring 7 is arranged between the large pipe sleeve 2 and the housing 3, one end of the spring 7 abuts against the end face position of the second step part 201 at the end part of the large pipe sleeve 2, and the other end abuts against the end face position of the first step part 303 at the front end of the housing 3, and the spring 7 is mainly used for exerting acting force on the housing 3 by using the elastic force of the spring 7 in a conventional state, so that the latch 4 is always at the root position of the front end of the slot 203, namely, is always in a locked state; in the unlocking state, the shell 3 and the latch 4 can be pressed by the elastic force of the spring 7, so that the telescopic pipe 6 is prevented from being separated when the length is adjusted.

Specifically, the front end of the small pipe sleeve 5 abuts against the end face position of the step part three 204 at the front end of the large pipe sleeve 2 so that the small pipe sleeve 5 is always located at the inner position of the large pipe sleeve 2, and the other end of the small pipe sleeve 5 is limited by the end part of the intermediate pipe 1 so as to limit the axial position of the small pipe sleeve 5.

Specifically, the tail end of the large pipe sleeve 2 is fixedly connected with a middle pipe 1, the outer wall of the large pipe sleeve 2 is provided with a second mounting hole 202, and the second mounting hole 202 is provided with a screw connected with the middle pipe 1; an extension tube 6 is installed inside the small tube sleeve 5, a structure for limiting the extension tube 6 to rotate relative to the small tube sleeve 5 is arranged between the extension tube 6 and the small tube sleeve 5, more specifically, a limiting groove 601 is arranged outside the extension tube 6, the length direction of the limiting groove 601 is parallel to the length direction of the extension tube 6, and a limiting protrusion 502 matched with the limiting groove 601 is arranged on the inner wall of the small tube sleeve 5, so that the small tube sleeve 5 and the extension tube 6 are prevented from rotating relatively.

In addition, in order to facilitate the rotation of the housing 3, the outer wall surface of the housing 3 is provided with an anti-slip groove 301 to increase the friction force with the hand in use.

The working principle is as follows: the middle pipe 1 is in threaded fit with the extension pipe 6, the length adjustment of the extension pipe 6 can be realized by rotating the extension pipe 6 (guessed here, and the writing is not right), and the horizontal bar lock catch mainly utilizes the meshing of the first tooth 401 and the second tooth 501 of the latch 4 to limit the rotation of the small pipe sleeve 5, so that the rotation of the extension pipe 6 is limited, and then the effect of preventing looseness is achieved; when adjusting, only need move the shell 3 backward to rotate the shell 3, can make the latch 4 move to the draw-in groove 203 rear end root position of big pipe box 2, at this moment, be in the unblock state, its length is adjusted to the accessible rotation flexible pipe 6, after finishing adjusting, with the shell 3 recovery normal position, make the first tooth 401 of latch 4 and the second tooth 501 intermeshing of little pipe box 5, can restrict flexible pipe 6's rotation, reach the purpose of locking.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
