Background
The connecting sleeve is applied to various mechanical fields and is commonly used for connecting a device to a cross rod, the sleeve part of the connecting sleeve commonly used in the market is generally designed into a closed structure, when the connecting sleeve is installed on the cross rod, the cross rod needs to be sleeved into the connecting sleeve in advance, and then the cross rod is installed, but once the connecting sleeve needs to be detached, the cross rod needs to be detached firstly so as to take down the connecting sleeve, and great trouble is brought to a user due to inconvenient design. In order to facilitate the assembly and disassembly, the present inventors have purposely designed the connecting pipe sleeve to be in a directly detachable state, but the directly detachable connecting pipe sleeve is generally locked by a locking device such as a screw, a bolt, etc., and in the use process, friction, collision, etc. can occur between the connecting pipe sleeve and the cross bar, and these forces may cause the locking device such as the screw, the bolt, etc. of the connecting pipe sleeve to generate certain abrasion and looseness. In some applications, the connecting sleeve is required to be in transition fit or close to transition fit with the cross rod, and the abrasion and loosening of the locking device inevitably affect the firmness of the connecting sleeve, so that the gap between the locking device and the cross rod is increased, and the use is affected, so that an improved connecting sleeve capable of adjusting the size of the connecting sleeve in real time is needed.

Detailed Description
As shown in fig. 1-3, an improved connecting pipe sleeve comprises a U-shaped pipe sleeve 1, a connecting block 2 and a bolt 3, wherein the top of the U-shaped pipe sleeve 1 is provided with a first arc guiding surface 11, two side walls 12 of the first arc guiding surface form a clamping part 121 with a tapered opening from top to bottom, and at least two groups of screw holes 4 which are correspondingly arranged are arranged at intervals along the length direction of the clamping part 121; the top of the connecting block 2 is provided with a concave second arc guide surface 21, when the connecting block 2 is sleeved in the clamping part 121 of the U-shaped pipe sleeve 1, a containing space 5 for containing a circular pipe is formed between the first arc guide surface 11 at the top of the U-shaped pipe sleeve 1 and the second arc guide surface 21 of the connecting block 2, the two side walls of the connecting block 2 are provided with positioning reference surfaces 22 matched with the clamping part 121 of the U-shaped pipe sleeve 1, the space between the two positioning reference surfaces 22 is gradually reduced from top to bottom, the positioning reference surfaces 22 are provided with positioning adjustment holes 122, the positioning adjustment holes 122 are opposite to screw holes 4 on the clamping part 121 of the U-shaped pipe sleeve 1, and the positioning adjustment holes 122 have adjustment allowance relative to the screw holes 4 along the vertical direction of the positioning reference surfaces 22 (namely, the vertical direction length of the positioning adjustment holes 122 is longer than that of the screw holes 4); the bolt 3 sequentially penetrates through the screw hole 4 and the positioning adjusting hole 122, and the relative position between the positioning adjusting hole 122 and the screw hole 4 in the vertical direction is changed by locking the bolt 3, so that the connecting block 2 is locked in the clamping part 121 of the U-shaped pipe sleeve 1. More preferably, the bottom of the connecting block 2 is provided with a connecting part 23 for externally connecting objects. The central axis of the connecting part 23 is perpendicular to the central axis of the accommodating space 5, the connecting part 23 can be externally connected with corresponding pipe fittings, the embodiment is a screw pipe fitting, and the connecting pipe sleeve can conveniently realize the connection of the pipe fittings perpendicular to each other through the connecting part 23. The clamping part 121 is formed by two inclined planes which are tapered from top to bottom; the positioning reference surface 22 formed by the two side walls of the connecting block 2 is also formed by two inclined surfaces which taper from top to bottom. As shown in fig. 3, the cross section of the U-shaped tube main body 1 is respectively composed of an arc section 111 and a clamping section 112 with a tapered opening; meanwhile, a straight line segment 113 for adjusting the vertical position is additionally arranged between the arc segment 111 and the clamping segment 112.
As shown in fig. 4, when the connecting sleeve is used, the bolt 3 is first disassembled, the connecting block 2 is removed, then the U-shaped sleeve 1 is clamped into the cross bar 6 which needs to be matched through the connected clamping part 121, then the connecting block 2 is clamped into the clamping part 121, the bolt 3 sequentially passes through the oppositely arranged screw hole 4 and the positioning adjusting hole 122 and is locked with the nut 31, the U-shaped sleeve 1 and the connecting block 2 are provided with matching surfaces with tapered openings from top to bottom, the positioning adjusting hole 122 and the screw hole 4 are provided with an adjusting allowance in the vertical direction, and the U-shaped sleeve 1 is also provided with a straight line section 113 for adjusting the position in the vertical direction, so when the bolt 3 is locked, the clamping part 121 is further used for clamping the connecting block 2, and due to the tapered structure, when the clamping part 121 further clamps the connecting block 2, the bolt 3 is upwards displaced along the positioning adjusting hole 122, so that the height difference between the second circular arc guide surface 21 and the first circular arc guide surface 11 is further reduced, and the connecting cross bar 6 can be stably and rotatably arranged in the connecting sleeve. If friction and collision are generated between the U-shaped pipe sleeve 1 and the cross rod 6 of the connecting pipe sleeve in the subsequent use process, the bolt 3 is further locked, so that the assembly is convenient.
