In the present embodiment, referring to fig. 2-5, an adjustable grab bar device is provided, which includes a base 2, a grab bar 1 and a slide block 3 fixed to the grab bar 1; the base 2 is provided with a hollow cavity, and the end part of the grab rail 1 far away from the roof is accommodated in the hollow cavity; a first end of the base 2 is provided with a connecting part 21, and the connecting part 21 is fixedly connected with a floor in the vehicle; the sliding block 3 is fixedly connected to the grab bar 1, the side wall of the base 2 is provided with a sliding groove 22, the sliding block 3 is accommodated in the sliding groove 22, and when the grab bar 1 moves up and down relative to the base 2, the sliding block 3 slides up and down in the sliding groove 22. When a heavy component such as a battery or a gas cylinder is arranged at the top of the vehicle and the vehicle runs on a bumpy road, the downward amplitude of vibration of the top in the vehicle is up to 5-10mm, and the grab bar 1 fixedly connected to the top in the vehicle sinks to drive the sliding block 3 to sink. The slider 3 moves downward along the slide groove 22 on the base 2, and the slider 3 and the slide groove 22 are subjected to only a small stress. Thus, the problem that the grab rail device in the prior art can not provide axial adjustment for the grab rail 1, and further the grab rail 1 is broken due to large stress is solved.
In this embodiment, it is preferable that the cross-sectional shape of the slider 3 is an oblong having a straight edge connected to the rest bar 1.
Alternatively, the slider 3 has a rectangular or square cross-sectional shape.
In this embodiment, correspondingly, in order to enable the grab rail 1 and the base 2 to move relatively and ensure the strength of the grab rail base 2 after the hole is formed, the side wall of the base 2 is provided with the oblong sliding groove 22, and the periphery of the hole is in round corner transition, so that the generation of cracks caused by stress concentration is avoided.
Optionally, the sliding groove 22 is a rectangular hole, and corners of the sliding groove 22 are provided with rounded corners.
Preferably, the number of the sliding blocks 3 is 4, and the sliding blocks 3 are arranged on two symmetrical surfaces of the circumference of the grab bar 1, so that when the grab bar 1 moves up and down, the sliding blocks 3 can be ensured to smoothly slide in the sliding grooves 22.
It should be noted that the number of the sliders 3 is not limited to the above 4, and may be 2, 6 or other numbers; other arrangements of the slider 3 are possible; of course, the shape of the slide groove 22 is not limited to the above-described oblong hole or rectangular hole, and holes of other shapes may be applied to the slide groove 22 as long as the same function can be achieved.
In this embodiment, the sliding block 3 is fixedly connected with the grab rail 1 through the screw 6 to ensure the fastening connection, so that the grab rail 1 drives the sliding block 3 to sink simultaneously when sinking.
Further, the inner side of the slider 3 is closely attached to the grab bar 1, and in order to position the screw 6 for mounting the slider 3, the mounting surface of the screw 6 is recessed by a mounting surface. The mounting surface is an arc concave surface which is inosculated with the outer wall of the grab rail 1, and the arc concave surface is provided with a screw hole for the screw 6 to pass through.
In this embodiment, it is preferable that the slider 3 is made of a high-strength self-lubricating nylon material since the slider 3 often rubs against the slide groove 22.
The material of the slider 3 is not limited to the nylon, and may be PP, ABS, or the like, and of course, other materials having high strength self-lubricating property may be applied to the slider 3 as long as the same function can be achieved.
In this embodiment, because grab bar 1 can reciprocate relative base 2 in the in-service use in-process, if grab bar 1 direct contact base 2, can send the abnormal sound, so set up the bolster between the contact surface of grab bar 1 and base 2.
Preferably, the buffer member is a bushing 4, the bushing 4 has an outer circular flange, and a sleeve of the bushing 4 is inserted into the hollow cavity of the base 2 from the second end of the base 2.
Further preferably, the bushing 4 is wear resistant and noise resistant, so nylon bushings are also used.
The material of the bush 4 is not limited to the nylon, and other materials having high strength and self-lubricating properties may be applied to the bush 4 as long as the same function can be achieved.
In this embodiment, the first connection hole is formed in the connection portion 21, the second connection hole is formed in the floor in the vehicle, and the screw penetrates through the first connection hole and the second connection hole to fixedly connect the connection portion 21 with the floor in the vehicle, so that the base 2 is firmly and stably connected with the floor in the vehicle.
In another embodiment, the adjustable grab bar device further comprises a decoration piece 5, and the decoration piece 5 covers the base 2.
Further, the garnish 5 is in a hood shape, and a garnish hood is formed outside the base 2. The sliding groove 22 of the sliding block type grab bar device is arranged outside, and the protrusion of the screw 6 for fixing the sliding block 3 is also arranged outside, so that the appearance of the base device is influenced; in addition, small garbage, dust and the like can easily enter the base 2, therefore, the decoration of the decoration piece 5 is added on the outer portion of the grab rail base 2, and the attractiveness of the grab rail device is greatly improved after the decoration piece 5 is added.
The utility model discloses a grab rail device with adjustable divide into fixed part and movable part. The base 2 is fixed to the floor in the vehicle by screw connection, and then the armrest seat decoration 5 is covered and buckled on the base 2 as a fixed part. One end of the grab rail 1 is fixed on the top cover in the vehicle, and the other end is connected with the grab rail base device. The grab bar 1 extends downwards from the top of the vehicle and then penetrates into the hollow cavity of the base 2 from the upper part of the base 2. The bushing 4 needs to be installed in advance before the grab bar 1 is inserted into the base 2. After the grab bar 1 is inserted into the base 2, the slide block 3 is connected to the grab bar 1 by the screw 6 and fixed on the roof as a movable part. When a heavy component such as a battery or a gas cylinder is arranged at the top of the vehicle and the vehicle runs on a bumpy road, the downward amplitude of vibration of the top of the vehicle is up to 5-10 mm. At the moment, the roof in the vehicle sinks to drive the grab rail 1 to sink; the grab bar 1 sinks to drive the slide block 3 to sink, the slide block 3 moves downwards along the slide groove 22 on the base 2, and the slide block 3 and the slide groove 22 only bear little stress. Therefore, the problem that the grab rail base 2 in the prior art can not provide axial adjustment for the grab rail 1, and the grab rail 1 is broken due to large stress is solved.
The above embodiment of the utility model has following beneficial effect: the adjustable grab bar device of the utility model has the advantages that through the arrangement of the sliding block and the sliding groove on the base, as the sliding block is fixedly connected with the grab bar, when the height in the vehicle changes and the sliding block slides in the sliding groove, the relative position of the grab bar in the axial direction and the base can be adjusted, the stress applied to the grab bar in the actual use process is reduced, and the problem that the grab bar is easy to break is solved; moreover, because screws are not adopted to simultaneously penetrate through the grab rail and the grab rail base for connection and fixation, the problem that the screws of the grab rail base are easy to break in the prior art can be solved; in addition, the adjustable grab rail device adopts the decorative cover, has beautiful structure, convenient installation and lower manufacturing cost, and simultaneously improves the use comfort and riding safety of the grab rail.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
