Description

[Detailed description of the invention] [Industrial field of application] This invention is for installing a pipe protector at key terminal points of a pipe protector that is installed to cover the pipe in order to protect the pipe of a vehicle such as an automobile. Regarding structure.

[Prior art] Conventional pipe protector 20 for vehicles such as automobiles
The mounting structure will be explained with reference to FIGS. 8 and 9.

In the piping 10 in the vehicle engine room, etc.
In order to protect the piping 10 from radiant heat from the engine or flying stones, mud, etc. caused by driving the car,
In some cases, the protector 20 may also be applied.
The fixing method has generally been to use adhesive tape or adhesive, or mechanically fix it using fastening screws, clips, or the like. In the actual assembly, the protector 20 is set in advance on the piping 10 on the vehicle side, and then a normal hose clamp 3a is tightened in this position to fix the aforementioned piping 10, and then the aforementioned protector is After moving the protector 20, the protector 20 is fixed with the next hose clamp 3b.

By the way, in the middle of the above piping 10,
Although it is suitable for parts that can be performed before vehicle assembly, work space can sometimes become a problem for parts that can be performed only after vehicle assembly.

In addition, there was a tendency for the number of component parts of the protector 20 to increase and for the assembly quality of the protector 20 to become unstable.

If we list the conventional problems with the mounting structure of these piping protectors 20, they are as follows: (1) In both of the hose clamps 3a and 3b mentioned above, it is always difficult to identify each size depending on the size of the clamp diameter. was necessary, and it was quite troublesome in terms of parts management.

(2) Furthermore, it has always been difficult to determine the mounting position of the protector 20 in the longitudinal direction at the end of the pipe.

(3) Hose clamp 3 of conventional protector 20
In the case of tightening b, there was a considerable difference in the diameter of the clamp 3b, and it took too much time to narrow down the clamp diameter. Due to these various reasons, the assembly workability was poor.

[Purpose of the invention] The purpose of this invention is to eliminate the various drawbacks of the conventional piping protector mounting structure as described above, and to improve the installation structure for the piping on the vehicle side and the piping at the connection part of the vehicle. A mounting part suitable for use as a clamp-like hanging member is newly attached to the protector terminal, and the mounting performance of the protector is significantly improved. It is intended to provide a mounting structure.

[Structure of the invention] This invention is a pipe protector that is installed to cover the pipes of vehicles such as automobiles in order to protect the pipes. A protector for automobile piping, in which a flat plate-shaped hanging member is fixed to the bottom edge of the notch toward the end, and this hanging member is hung on the tightening bolt shaft of a hose clamp that tightens the piping connection part. This is the mounting structure.

Furthermore, in the mounting structure for an automobile piping protector, a hook-shaped locking pawl is formed in advance on the free end of the locking member for locking onto the tightening bolt shaft.

[Example] Each example of this invention will be described in detail below with reference to the drawings.

First, FIG. 1 is a perspective view of the entire installation and installation of the piping protector of this invention. In the figure, 1 is a bent heater hose having a predetermined inner diameter and length. This bent heater hose 1 plays the role of a bendable part of the metal pipe 10, and the end of this metal pipe 10 and the end of the other metal pipe 11 are connected to the above-mentioned bent heater hose 1. Both terminals are
It is fitted in a liquid-tight manner. Both ends of this heater hose 1 are also fastened with respective hose clamps 3, 3'. Further, in a portion A in the figure, a protector 2 of this invention is fastened to one end of the heater hose 1.
Note that the metal pipe 11 is configured to extend toward the engine side.

Next, Fig. 2 is an exploded perspective view showing the components of section A in Fig. 1 of the first embodiment of the piping protector of this invention, and Fig. 3 is a side view of the first embodiment. be.

In this first embodiment, a U-shaped notch 21 is provided at the end of the piping protector 2 in order to protect a hanging member 4, etc., which will be described later.
A latching member 4, which is a flat metal strip coated with vinyl chloride, is fixed to the rivet portion 23 in one place in the fastening hole 22 on the bottom edge in the direction in which the terminal is released. As shown by the arrow in FIG.
The free end is wrapped around the threaded part of the screw and fixed.

Next, FIG. 4 is an exploded perspective view of a second embodiment of the piping protector of this invention, and FIG. 5 is a side view of the second embodiment. In this second embodiment,
A U-shaped notch 21 is provided at the end of the piping protector 2', and flat spring steel hooks are inserted into the fastening holes 22 at the bottom edge of the 21 notches in the direction in which the end opens. A hanging member 5 with a hook-shaped claw is set at the riveted part 23, and the downward hook is attached to the threaded part of the tightening bolt 6 of the hose clamp 3. A hanging member 5 with a hook-shaped claw 51 is hooked on the hook 51 in place of a shaped claw 51 or a clamp.

Next, FIG. 6 is an exploded perspective view of a third embodiment of the piping protector of this invention, and FIG. 7 is a side view of the third embodiment. In this third embodiment,
A U-shaped notch 21 is provided at the end of the piping protector 2'', and a flat spring rigid hook is inserted into the fastening hole 22 at the bottom edge of the 21 notches in the direction in which the end opens. A latching member 5' with a hook-shaped claw is set at the riveted portion 23, and this upward cut is attached to the threaded part of the tightening bolt 6 of the hose clamp 3 with the latching member 5' with a hook-shaped claw. Raising hook-shaped claw 51'
Alternatively, in place of a clamp, a hook-shaped hook 51' is attached to the hook member 5'.

The protectors 2, 2′ devised in this way,
2'' mounting method, wherein the protector 2,
A hooking member 4 or a hook-shaped hooking member 5, 5' is set in the notch 21 at the 2', 2'' end, and the hooking member 4 or the hooking member 5, 5' with a hook-shaped claw is set on the threaded part of the tightening bolt 6 of the hose clamp 3. The structure is such that the protectors 2, 2', 2'' are fixed by hooking the member 4, the hook-shaped hook-equipped hook members 5, 5', and the like.

[Effect of the invention] The structure of the protector for automobile piping constructed as described above is such that the protector terminal is notched in a U-shape, and the latching member is attached to the riveted portion at the back of this notch, facing toward the opening of the terminal. is set, and each protector is equipped with a piping protector mounting structure in which each protector is wrapped around the threaded part of the tightening bolt of the hose clamp in use. It is possible to assemble the protector in a narrow space by setting the protector on the piping on the vehicle side in advance.
At this position, tighten the usual latching member to fix the aforementioned piping, then move the same protector, and then install a protector suitable for the piping on the vehicle side and the piping at the connection there. Performance can be greatly improved and this installation is stable.
Therefore, there is no problem with the protector's inherent radiant heat and protection against muddy water, and it can be said to be a device with great practical value, as it effectively provides protection for the inserted items.
