This makes the rack 3 heavy and takes up a large space compressing the cable laying space. In addition, the installation process of the cable involves a riveting process between the bracket 3 and the i-shaped member 1 and a screwing process of the clamp and the bracket 3, and it takes a long time for a worker to install the cable. Finally, under the condition that the cable looseness is large or the clamp fails, the cable is easily in direct contact with the I-shaped component 1, and under the environment condition of long-term vibration, the risk of short circuit and the like of a circuit is easily caused by abrasion.
Based on this, it is necessary to design a new fixing device.

In the following detailed description, directional terms, such as "upper", "lower", "inner", "outer", "longitudinal", "lateral", and the like, are used with reference to the orientation depicted in the accompanying drawings. The components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.
Referring to the securing device 100 for securing a tubular member 400 to an I-shaped member 200 as shown in FIGS. 2-3, FIG. 3 shows the securing device 100 in an opposite orientation to that shown in FIG. 2. As shown in fig. 2 and 3, the fixing device 100 includes a base plate 110, two upper limiting plates 120, and two lower limiting plates 130. The fixation device 100 is a resilient plastic member, preferably a structural member made of nylon 66.
The base plate 110 is a plate-shaped member extending in a width direction of the i-shaped member 200 (corresponding to the X-axis direction of fig. 2), and includes a pair of long sides 112 extending in a lateral direction of the i-shaped member 200 (corresponding to the X-axis direction of fig. 2) and a pair of short sides 114 substantially parallel to a longitudinal direction of the i-shaped member 200. At least one lateral end of the base plate 110 can extend beyond a lateral side edge 210 of the i-shaped member 200. Preferably, both lateral ends of the base plate 110 protrude from the lateral side edges 210 of the i-shaped member 200.
It should be noted that the "long side" does not necessarily mean longer than the "short side", and the "long side" and the "short side" are only used to distinguish the side edges of the substrate 110 in different directions in the present disclosure.
The upper limiting plates 120 are disposed opposite to each other at the long sides 112 of the base plate 110 and extend upward substantially perpendicular to the upper surface of the base plate 110, thereby constituting a passage for the tubular member 400 together with the upper surface of the base plate 110. In the embodiment of fig. 2-4, the number of the upper limiting plates 120 located on the same side of the substrate 110 is 1, and for reasons of arrangement requirements and light weight, a plurality of upper limiting plates 120 spaced apart from each other may be provided on the same side of the substrate 110. The upper limiting plate 120 is optionally provided with lightening holes 113 for lightening.
When the tubular member 400 to be fixed by the fixing device 100 is not in a regular cylindrical shape, the upper limiting plate 120 may be adaptively changed to a non-flat plate type shape.
The lower limiting plates 130 extending downward from the lower surface of the base plate 110 are parallel to the short sides 114 of the base plate 110, and the distance between the lower limiting plates 130 of the opposite sides is configured to match the lateral width (width corresponding to the X-axis direction of fig. 2) of the i-shaped member 200, thereby enabling the fixing device 100 to be reliably snapped onto the i-shaped member 200.
In some embodiments (embodiment one), as shown in fig. 2 and 3, the lower retainer plates 130 are provided in pairs on opposite sides of the base plate 110, and flanges 132 for being snapped into the i-shaped member 200 are provided on opposite surfaces of the lower retainer plates 130 provided in pairs. The lower retainer plate 130 can more securely snap-fit the fixture 100 to the i-shaped member 200 by the flange 132.
The distance between the flange 132 and the lower surface of the base plate 110 is equal to or slightly smaller than the thickness of the cross plate of the i-shaped member 200 (corresponding to the dimension in the Y-axis direction of fig. 2), so that the upper surface of the cross plate abuts against the lower surface of the base plate 110 and the lower surface of the cross plate abuts against the upper surface of the flange 132.
In other embodiments (embodiment two), which are not shown, the lower retainer plate 130 is formed at an acute angle to the lower surface of the substrate 110. The lower limiting plates 130 of the opposite sides are gradually drawn in a direction away from the substrate 110. The lower retainer plate 130 may also secure the fixture 100 to the i-shaped member 200 by the clamping action of the opposing lower retainer plate 130 against the i-shaped member 200. In this embodiment, the lower limiting plate 130 is optionally provided with or without the flange 132 of the first embodiment.
According to some preferred embodiments of the present invention, the lower surface of the base plate 110 is provided with a plurality of downwardly protruding limiting mechanisms (protrusions 116) which are engaged with the predetermined recesses 216 of the i-shaped member 200. Alternatively, the lower surface of the substrate 110 forms the recess 216, and the protrusion 116 is preset on the i-shaped member 200. Or the base plate 110 is provided with a plurality of protrusions 116 and a plurality of recesses 216, and the i-shaped member 200 is provided with the recesses 216 and the protrusions 116, the number and the positions of which are matched with those of the protrusions 116 and the recesses 216.
Preferably, an interference fit is used between the protrusion 116 and the depression 216.
Referring to the view of fig. 2, according to the fixing device 100 of the first embodiment, the lower limiting plate 130 limits the fixing device 100 in the X-axis direction, the flange 132 of the lower limiting plate 130 limits the fixing device 100 in the Y-axis direction, and the protrusion 116 and the recess 216 limit the fixing device 100 in the Z-axis direction. In the fixing device 100 according to the second embodiment, the lower stopper plate 130 restricts the fixing device 100 in the X-axis and Y-axis directions, and the protrusion 116 and the recess 216 restrict the fixing device 100 in the Z-axis direction. In the case where the flange 132 is provided, the surface of the lower retainer plate 130 and the flange 132 simultaneously position the fixture 100 in the Y-axis direction.
In order to better secure the tubular member 400 within the channel, the extension of the base plate 110 beyond the lateral side edge 210 of the i-shaped member 200 is preferably provided with at least two through holes 118. The through hole 118 is used for inserting the fixing clip 300.
In use, the opposing lower retainers 130 are first opened outwardly and pressed down to pre-clamp the fixture 100 to the i-shaped member 200, the fixture 100 is then moved longitudinally along the i-shaped member 200 to align the corresponding recesses 216 and protrusions 116 with one another, and the fixture 100 is pressed down again so that the lower surface of the base 110 of the fixture 100 conforms to the upper surface of the i-shaped member 200. After the fixture 100 is tightly secured to the i-shaped member 200, a tubular member 400, such as a cable, is placed within the channel defined by the upper limiting plate 120. Finally, the cable is locked by the strap 300 and is tightly fixed as shown in fig. 4.
In the above process, in order to further improve the ease of installation. The clip 300 for fixing the cable may be previously inserted into the through hole 118 of the substrate 110 and then the fixing device 100 may be installed. This may prevent a worker from fixing the clip 300 in a relatively narrow space.
As can be seen from the above, the fixing device 100 of the present invention has the following advantages:
a) since the plurality of lightening holes 113 are provided, it has a light weight. In addition, since the fixing device 100 does not have to bear the weight of the tubular member 400, it may use a lightweight plastic member, which may further reduce the overall weight of the fixing device 100.
b) Because the fastener is not needed, the device has the characteristics of simple and convenient installation and disassembly;
c) in the vertical direction, the fixing device 100 does not need to occupy additional space, thereby being beneficial to increasing the arrangement space of the cable;
d) the cables are encapsulated in a relatively closed manner by the upper limiting plate 120, which further improves the risk of direct contact of the cables with the surrounding structure.
The scope of protection of the present invention is limited only by the claims. Persons of ordinary skill in the art, having benefit of the teachings of the present invention, will readily appreciate that alternative structures to those disclosed as possible may be substituted for the alternative embodiments disclosed, and that the disclosed embodiments may be combined to create new embodiments, which likewise fall within the scope of the appended claims.
