[0002] In prior art, when the hose is connected with the joint, the port of the hose is usually inserted into the connecting part of the joint, and then the pipe is fixed and installed on the joint by the way of binding band or iron wire on the outside of the pipe, but this way is troublesome, low in efficiency and insufficient in the connection firmness of the pipe and the joint, and the pipe is easy to drop when the medium pressure in the pipe is large. Therefore, the joint structure of pipe anti -drop is provided. SUMMARY

[0003] The utility model discloses a joint structure of pipe anti -drop, which solves the above problems.

[0004] In order to achieve the above purpose, the utility model provides a joint structure of pipe anti -drop, which comprises a joint, characterized by further comprising a locking sleeve that is installed on the joint by clamping to tightly install the pipe on the joint.

[0005] Further preferably, the locking sleeve is provided with a locking block matched with the locking part and a pressing part that cooperates with the connecting part to tightly install the pipe on the connecting part.

[0006] Further preferably, further comprising a cavity arranged between the locking sleeve and the pressing part, which can make the pressing part expand outward after being pressed.

[0007] Further preferably, further comprising a guide part arranged in an arc shape at the front end of the pressing part.

[0008] Further preferably, further comprising a guide surface arranged in an inclined manner on the locking block.

[0009] Further preferably, the locking part is a clamping groove arranged on the joint.

[0010] The utility model has the advantages that the locking sleeve is arranged to tightly install the pipe on the joint, which is simple, fast and firm, and is not easy to drop. BRIEF DESCRIPTION OF DRAWINGS

[0017] Now we make further description to the joint structure of the pipe anti-falling in the utility model in combination with the drawings.

[0018] It should be noted that, all directionality indications such as up, down, left, right, front, back, etc. in the embodiments of the utility model are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture such as shown in the drawings, if the specific posture changes, the directionality indications also change accordingly.

[0019] In the utility model, unless otherwise explicitly specified and limited, the terms "connection", "fixation" and the like should be understood broadly; for example, "fixation" can be fixed connection, or detachable connection, or integral; can be mechanical connection, unless otherwise explicitly limited. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0020] Referring to Figures 1-5 A joint structure of pipe anti-falling, comprising a joint 1; characterized by further comprising a locking sleeve 2 installed on the joint 1 by clamping to tightly install the pipe on the joint 1; the joint 1 is provided with a connecting part 3 connected with the pipe and a locking part 4 connected with the locking sleeve 2;

[0021] Through the setting of the locking sleeve 2, the pipe is tightly installed on the joint 1, which is simple, fast and firm, and is not easy to fall off.

[0022] In one embodiment, the locking sleeve 2 is provided with a locking block 5 matched with the locking part 4 and a pressing part 6 cooperating with the connecting part 3 to tightly install the pipe on the connecting part 3;

[0023] The pipe is installed on the connecting part 3 by inserting, and when the locking sleeve 2 is installed on the joint 1, the pipe is tightly installed between the connecting part 3 and the pressing part 6 by the pressing part 6, which improves the firmness of the pipe installation and connection and avoids easy falling off.

[0024] Further preferably, the cavity 41 is arranged between the locking sleeve 2 and the pressing part 6, so that the pressing part 6 can expand outward after being pressed.

[0025] In one embodiment, the guiding part 7 is arranged in an arc shape at the front end of the pressing part 6.

[0026] The guiding part 7 can guide the pressing part 6 to be installed on the joint 1.

[0027] In one embodiment, the guiding surface 8 is arranged in an inclined shape on the locking block 5, and the locking part 4 is a clamping groove arranged on the joint 1.

[0028] The guiding surface 8 can guide the locking block 5 to be clamped into the clamping groove, so that the locking block 5 can be clamped into the clamping groove without interference.

[0029] In the installation of the utility model, first, the locking sleeve 2 is sleeved on the pipe, then the pipe is inserted into the connecting part 3 of the joint 1, then the locking sleeve 2 is moved along the pipe to the joint 1, until the locking block 5 on the locking sleeve 2 is moved into the clamping groove, the clamping and installation of the locking sleeve 2 on the joint 1 are completed, at this time, the pressing part 6 on the locking sleeve 2 presses the pipe, so that the pipe is clamped and installed between the connecting part 3 and the pressing part 6.

[0030] The protection scope of the utility model is not limited to the above embodiments and their transformations. The routine modifications and replacements made by the skilled in the art based on the content of the embodiments all belong to the protection scope of the utility model.
