Description

[Detailed explanation of the invention] (Industrial application field) This invention has a tube in the protector body.
This invention relates to an improved structure of a tube protector for piping.

(Prior Art) Recently, fuel tubes and brake oil tubes in automobiles have been adopted as a centralized piping system, where they are arranged side by side on a predetermined side of the body and protected by a tube protector. Conventionally, for example, a tube protector 21 shown in FIG.
A structure in which a grommet portion 23 for fixing the tube T is integrally molded on the protector main body 22 is used as shown in FIG. Since the grommet part 23 engages and fixes a plurality of tubes T in parallel, a locking groove 25 that prevents the tubes from coming off is formed by the locking pieces 24 to 24 arranged in succession.
-25 are formed, each tube T-T is engaged with the locking groove 25-25 of the grommet part 23,
A tube protector 1 in which tubes T to T are engaged is attached to a body.

(Problems to be Solved by the Invention) However, in the conventional tube protector 21 described above, the grommet portion 23 is integrally molded with the protector main body 22, and the locking grooves 25 of the grommet portion 23 are arranged in a series in a limited width. Since the tubes are placed in the tubes, the spacing is narrow, making it difficult to insert the tubes, requiring a large amount of force when inserting the tubes, and making it difficult to engage and fix the tubes. Further, there was a problem that the tube might be deformed due to the large force when inserting the tube.

Therefore, the purpose of this invention was to solve the above-mentioned problems with the conventional tube protector in which the tubes are fixed to the protector body. without damaging the tube to be fixed.
Another object of the present invention is to provide a structure of a tube protector that has good tube fixation properties.

(Means for Solving the Problems) In order to achieve the above object, the means of this invention is such that tube locking portions are provided at first and second predetermined intervals in the longitudinal direction of the tube piping side of the protector body. In a tube protector of a type in which a plurality of tubes are provided in the width direction and the tubes are fixed to the piping at first and second tube locking parts, each of the first and second tube locking parts has a tube at the upper end. The protector body consists of a pair of locking pieces having locking claws and a receiving piece located between both the locking pieces, and both the locking pieces and the receiving piece are designed to apply appropriate bending tension to lock the tube. The structure of the tube protector is formed by dispersing the tubes in the longitudinal direction.

(Operation) The tube is engaged and fixed by the first and second tube locking parts. That is, the left and right sides of the tube are regulated by one and the other dispersed locking piece, the lower end is regulated by the receiving piece, the upper end is regulated by the locking claw of the locking piece, and the bending tension is regulated. It will be fixed in the fixed position.

(Example) Next, an example of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing the tube attachment side of the tube protector 1, in which first and second tube locking portion groups 6, 1 are attached to the elongated protector body 2.

Both receiving pieces 7A to 7D, 12 in the above embodiment
A~12D and both locking pieces 8A~8D, 13A~
13D is designed to generate vertical bending tension in the tubes T1 to T4, but the bending tension of the tube is such that the distance between the pair of locking pieces on the left and right holding sides of the tube is slightly smaller than the outer diameter width of the tube with respect to the pair of receiving pieces. It is possible to arrange the tube narrowly so as to apply a deflection tension in the left and right direction to the tube for piping (not shown).

(Effect of the invention) Accordingly, the present invention provides a tube protector in which the tube is fixed to the pipe at the first and second tube locking parts of the protector main body. Since the pair of locking pieces and receiving pieces are dispersedly formed, even if multiple tube locking parts are installed in a row, there is more space in the width direction compared to the conventional grommet part, and the tube locking parts are separated. It is convenient that the tube can be fixed to the stopper part with a small force, easy to fit, and the tube will not be damaged during fixation.

In the present invention, the left and right sides of the tube are regulated by both locking pieces, and the tube is fixed by being regulated by the receiving piece at the lower end and the locking pawl of the locking piece at the upper end. Further, both the locking pieces and the receiving piece of the tube locking part of the present invention are arranged in a dispersed manner so as to give an appropriate bending tension to the tube, so that the tube is fixed in a state where the bending tension is applied. The fixation of the tube is good.
