Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a pipe holder that can be inserted into a threaded stud with a single touch while ensuring the strength of attachment to the threaded stud.

PRIOR TECHNOLOGY Conventionally, a pipe holder has a main body portion into which a threaded stud is inserted in the center, and a main body portion on both sides of the main body portion, as disclosed in Japanese Patent Application Laid-Open No. 58-687. It is known that a pipe holding part is provided in the pipe holding part. However, this Japanese Patent Application Publication No. 58-687
The pipe holder disclosed in the publication has a straight cylindrical main body to which it is inserted, so when inserting the pipe holder into a threaded stud, each thread of the threaded stud is There is a problem in that it is difficult to insert the pipe holder into the threaded stud with a single touch because it encounters insertion resistance when it comes into contact with the inner wall of the main body to be inserted. Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 57-93027, two pairs of claws are provided at intervals in the direction of insertion of the threaded stud on a pair of leg pieces corresponding to the main body for insertion. The pipe holder is inserted into the threaded stud with a single touch by forming a thin wall part on the pair of legs so that the diameter of the pair of legs expands in the direction of moving away from each other when the threaded stud is inserted. There are also known methods that make it easier. However, although the pipe holder disclosed in JP-A-57-93027 allows the pipe holder to be inserted with one touch, if the threaded stud is inserted at an angle with respect to the pair of leg pieces, Since the diameter of the pair of leg pieces is forcibly expanded, there is a risk that the pair of leg pieces may be damaged at the thin portion. Furthermore, since the pair of leg pieces are supported only by the thin portions, there is also the problem that the mounting strength is weak.

Purpose of the invention This invention was made in view of the problems of the above-mentioned prior art, and its purpose is to:
To provide a pipe holder that can be inserted into a threaded stud with a single touch while ensuring the strength of attachment to the threaded stud.

Structure of the invention In order to achieve the above-mentioned purpose, this invention consists of a main body to be inserted that is inserted into a threaded stud fixed to a panel, and a pipe that is pushed in and elastically grips the circumferential surface of the pipe. In a pipe holder made of synthetic resin and comprising a pipe gripping part provided with an elastic gripping piece, the main body part for insertion has a stud receiving hole into which the threaded stud is inserted, and the stud receiving hole has a stud receiving hole into which the threaded stud is inserted. A pair of elastic locking pawls that engage the threads of the threaded stud from opposite directions to sandwich the threaded stud are provided at intervals in the insertion direction of the threaded stud, and , two sets of guide pieces are provided at intervals in the insertion direction for regulating the threaded stud toward the center of the stud receiving hole of the main body for insertion, and one of the two sets of locking claws The locking claw is provided on the side closer to the receiving hole, and the other locking claw is provided between the two sets of guide pieces.

Function According to this invention, when inserting a pipe holder into a threaded stud with a single touch, two sets of guide pieces that restrict the threaded stud toward the center of the stud receiving hole allow the threaded stud to be screwed into place. The stud is guided to the center of the stud receiving hole, thereby preventing excessive force from being applied to the two pairs of locking claws. Also,
Two sets of guide pieces cooperate with two sets of a pair of locking claws to receive a lateral force applied to the pipe holder.
