Description

Technical Field

[0001] The utility model relates to a column bar, in particular to a sleeved column bar, and belongs to the technical field of column bars. Background Art

[0002] Column bars are long structural components that are commonly used in construction and home decoration. As key elements of support, connection and decoration, they can be made of various materials, including steel, aluminum, wood, plastic, etc. The appropriate material and specifications are selected according to application requirements.

[0003] In home decoration, column bars are a common structure, usually serving as the structural support part of furniture, used to connect different parts of furniture and provide fixed and stable connection points. For example, in the corners of cabinets or the edges of furniture, column bars can connect side panels, top panels and bottom panels to form a solid overall structure. However, when the length of some stable connection points that need to be provided is long and multiple column bars are required, most of them are welded together using welding devices, resulting in the inability to use the column bars without welding devices when connecting them, making it difficult to achieve tool-free quick self-connection, and failing to effectively reduce the difficulty of on-site operations. In addition, when a column bar needs to be replaced due to an accidental connection to the wrong column bar, it cannot be quickly disassembled, which increases the process of home decoration. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] The utility model provides a sleeved column bar, which can complete the rapid sleeve connection of the column bars and realize tool-free rapid self-connection.

[0006] (II) Technical solution

[0007] The utility model is realized by the following technical scheme: a sleeve-jointed column bar, comprising a sleeve, on which a connecting mechanism and a limiting mechanism are arranged;

[0008] The connecting mechanism includes an articulated frame fixed on one side of the sleeve, a threaded barrel is hinged inside the articulated frame, a threaded rod is threadedly connected to the inner wall of the threaded barrel, and one end of the threaded rod extends to the outside of the threaded barrel, a fixing plate is threadedly connected to the outer surface of the threaded rod, and the fixing plate is located above the threaded barrel, a limiting plate is fixed to the bottom surface of the fixing plate, and a turning handle is fixed to the top end of the threaded rod.

[0009] Preferably, the limiting mechanism includes a sliding rod that slides in contact with the inner wall of the sleeve, a handle is fixed to one end of the sliding rod located outside the sleeve, and an insert block is fixed to one end of the sliding rod located inside the sleeve. The sliding rod can be moved by pulling the handle, and the movement of the sliding rod can drive the insert block to move.

[0010] Preferably, a first telescopic spring is sleeved on the outer surface of the sliding rod, and the first telescopic spring is located between the handle and the plug block. The first telescopic spring can be squeezed by the movement of the plug block, so that the first telescopic spring can generate a corresponding elastic force, so that the plug block is subjected to a force opposite to its sliding direction.

[0011] Preferably, a support plate is fixed to the inner wall of the sleeve to support the insertion rod, and an insertion rod is fixed to the upper surface of the support plate. The position of the column bar body can be further limited by the arranged insertion rod, making the connection more stable.

[0012] Preferably, a plurality of telescopic rods are fixed to the upper surface of the support plate, and each telescopic rod is arranged in an equilinear manner. When the limiting fixation of the column bar body is released, the elastic force generated by the compression of the telescopic rods can push the column bar body to move along the inner wall of the sleeve, thereby enabling the column bar body to be disassembled more conveniently and quickly.

[0013] Preferably, the outer surface of each telescopic rod is sleeved with a second telescopic spring, and the bottom end of each second telescopic spring is fixed to the upper surface of the support plate. The provision of the second telescopic spring can effectively reduce the direct pressure on the telescopic rod when it is subjected to force, reduce the risk of damage caused by abnormal conditions, thereby extending the service life of the telescopic rod and increasing its elasticity.

[0014] Preferably, the plug block is in a triangular shape, and a sealing gasket is provided on the inner wall of the sleeve, so that the sleeve connection between the column bar body and the sleeve can be tighter.

[0015] The utility model provides a sleeve column bar, which has the following beneficial effects:

[0016] 1. The sleeved column bar is to insert the column bar body into the interior of the sleeve, and then the threaded tube is flipped toward the direction of the column bar body, and then the fixed plate and the limit plate are slid into the limit groove of the column bar body, and then the handle is turned to drive the threaded rod to rotate, and the threaded rod can drive the fixed plate to move during the rotation. When the limit plate contacts the limit block and contacts the column bar body, the connection of the column bar body can be completed, thereby realizing tool-free quick self-connection, reducing the difficulty of on-site operation and realizing quick disassembly.

[0017] 2. For the sleeved column bar, when the column bar body is inserted into the sleeve, the bottom end of the column bar body will squeeze the inclined surface of the plug block, and under the squeezing force, the slide bar will extend along the inclined surface of the corresponding plug block to the outside of the sleeve, and the plug block will compress the first telescopic spring at this time. When the plug block is inserted into the corresponding slot in the column bar body, the squeezing force disappears. At this time, the elastic force of the first telescopic spring in a compressed state drives the corresponding plug block to pop out and be snapped into the corresponding slot, thereby completing the further connection of the column bar body and increasing its stability and safety during sleeve connection.

[0031] The connecting mechanism 2 includes an articulated frame 201 fixed on one side of the sleeve 1, and a threaded tube 202 is hinged inside the articulated frame 201. The inner wall of the threaded tube 202 is threadedly connected to a threaded rod 203, and one end of the threaded rod 203 extends to the outside of the threaded tube 202. The outer surface of the threaded rod 203 is threadedly connected to a fixing plate 204, and the fixing plate 204 is located above the threaded tube 202. A limiting plate 206 is fixed to the bottom surface of the fixing plate 204, and a turning handle 205 is fixed to the top of the threaded rod 203. A limiting groove 801 is provided on the side of the column bar body 8, and a limiting block 802 is fixed to the inner bottom wall of the limiting groove 801.

[0032] Insert the column bar body 8 into the interior of the sleeve 1, then flip the threaded tube 202 toward the direction of the column bar body 8, then slide the fixing plate 204 and the limiting plate 206 into the limiting groove 801 of the column bar body 8, and then turn the handle 205, the handle 205 can drive the threaded rod 203 to rotate, and the threaded rod 203 can drive the fixing plate 204 to move during the rotation process, when the limiting plate 206 contacts the limiting block 802 and contacts the column bar body 8, the connection of the column bar body 8 can be completed.

[0033] Please refer to Figure 1 , Figure 3 and Figure 5 The limiting mechanism 3 includes a sliding rod 301 that slides in contact with the inner wall of the sleeve 1, a handle 304 is fixed to the end of the sliding rod 301 located outside the sleeve 1, and an insert block 302 is fixed to the end of the sliding rod 301 located inside the sleeve 1.

[0034] When the column bar body 8 is inserted into the sleeve 1, the bottom end of the column bar body 8 will squeeze the inclined surface of the plug block 302. Under the squeezing force, the slide bar 301 will extend to the outside of the sleeve 1 along the inclined surface of the corresponding plug block 302. At this time, the plug block 302 will compress the first telescopic spring 303. When the plug block 302 is inserted into the corresponding slot 803 in the column bar body 8, the squeezing force disappears. At this time, the elastic force of the first telescopic spring 303 in the compressed state drives the corresponding plug block 302 to pop out outward and snap into the corresponding slot 803, thereby completing the further connection of the column bar body 8.

The outer surface of each telescopic rod 6 is sleeved with a second telescopic spring 7, and the bottom end of each second telescopic spring 7 is fixed to the upper surface of the support plate 5. The provision of the second telescopic spring 7 can effectively reduce the direct pressure of the telescopic rod 6 when it is subjected to force, reduce the risk of damage caused by abnormal conditions, thereby extending the service life of the telescopic rod 6 and increasing its elasticity.

[0037] When the utility model is in use: the column bar body 8 is inserted into the sleeve 1, at this time, the bottom end of the column bar body 8 will squeeze the inclined surface of the plug block 302, and under the squeezing force, the slide bar 301 will extend to the outside of the sleeve 1 along the inclined surface of the corresponding plug block 302, and at this time, the plug block 302 will compress the first telescopic spring 303, and when the plug block 302 is inserted into the corresponding slot 803 in the column bar body 8, the squeezing force disappears at this time, and the elastic force of the first telescopic spring 303 in the compressed state drives the corresponding plug block 302 to pop out outward and be snapped into the corresponding slot 803, thereby completing the further connection of the column bar body 8, otherwise, the pull handle 304 is pulled to increase its stability and safety during sleeve connection.

[0038] At the same time, the threaded tube 202 is flipped toward the direction of the column bar body 8, and then the fixing plate 204 and the limiting plate 206 are slid into the limiting groove 801 of the column bar body 8, and then the turning handle 205 is turned, and the turning handle 205 can drive the threaded rod 203 to rotate, and the threaded rod 203 can drive the fixing plate 204 to move during the rotation.
