Description

Technical Field

[0001] The utility model belongs to the technical field of railway detection instruments, in particular to a portable instrument fixing device. Background Art

[0002] Routine maintenance and repair of railway equipment requires measuring and recording a variety of data, including but not limited to current, voltage, frequency, length, pressure, and temperature. Currently, these data are measured using a variety of instruments, and the measured values ​​are recorded and regularly analyzed.

[0003] When using an instrument for measurement, the operator needs to hold the instrument and test leads, observe the instrument data and record it, and often also hold documents or other tools when performing measurements. Therefore, when operating a handheld instrument, it is easy for the instrument to fall from the hand and be damaged. Although the prior art uses a hanging rope to tie the instrument to prevent it from falling, the instrument still needs to be held in the hand, which is inconvenient.

[0004] In the prior art, the fixing device of the instrument is usually to set a strap on the instrument and then tie the strap to the arm, or to set Velcro on the strap and fix it with Velcro. However, this fixing method is not convenient for installing and disassembling the instrument. The adhesive surface of the Velcro is easy to tear, causing the instrument to fall. Moreover, after working for a long time, the strap is always in contact with the operator's arm, which is easy to form sweat, not only causing discomfort to the operator, but also causing the strap to slide on the arm, thereby causing the instrument to slide, affecting the detection work. Utility Model Content

[0005] In view of this, the present invention aims to provide a portable instrument fixing device to solve the problems in the prior art that the instrument fixing device is inconvenient to install and remove the instrument, and the straps increase the discomfort of the operator and affect the detection.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A portable instrument fixing device includes a plug assembly, a bracket assembly, and a strap assembly. The plug assembly is arranged on the top of the bracket assembly, the strap assemblies are arranged on both sides of the bracket assembly, and the instrument is arranged above the bracket assembly through the plug assembly.

[0008] The plug-in assembly includes a bottom plate, a U-shaped plug-in plate, a socket, a limit assembly, and a rotation adjustment assembly. The U-shaped plug-in plate and the bottom plate are sequentially arranged above the bracket assembly from top to bottom. The ends of both sides of the upper part of the U-shaped plug-in plate are provided with limit assemblies. The socket is provided with a through slot inside. The upper part of the U-shaped plug-in plate is inserted into the through slot. The rotation adjustment assembly is arranged inside the U-shaped plug-in plate. The upper part of the U-shaped plug-in plate is inserted into the through slot.

[0009] Furthermore, adhesive is provided on the top of the socket, and the socket is arranged below the meter through the adhesive.

[0010] Furthermore, the length of the U-shaped plug board is greater than the length of the socket, and the two limiting components extend out of the through slot for limiting.

[0011] Furthermore, the limiting assembly includes a limiting groove, a spring block, and a plurality of springs. The limiting groove is provided at the end portion of one side of the upper portion of the U-shaped plug-in plate. One end of the plurality of springs is provided on the side wall of the limiting groove, and the other end of the plurality of springs is connected to the spring block. The spring block is extended and retracted in the limiting groove by the plurality of springs.

[0012] The spring block is a right-angled trapezoidal structure, and the oblique side of the spring block is arranged on a side away from the spring.

[0013] The upper part of the U-shaped plug-in plate is inserted into the through slot, and the two trapezoidal spring blocks are squeezed and retracted into the corresponding limit slots, and the connected springs are squeezed. After the U-shaped plug-in plate is completely inserted into the through slot, the springs rebound and the two spring blocks extend out of the through slot to limit the socket, thereby fixing the instrument bonded to the socket. When the instrument needs to be removed, just press the two spring blocks to retract them into the limit slots, and the socket slides out of the U-shaped plug-in plate for quick removal.

[0014] Furthermore, the rotation adjustment assembly includes a rotating disk and a threaded rod. The rotating disk is disposed within the U-shaped insert. One end of the threaded rod is fixedly connected to the bottom of the rotating disk, and the other end of the threaded rod is threaded through the lower portion of the U-shaped insert and is threadedly connected to the base plate. When the fixed direction of the instrument needs to be adjusted, the rotating disk is rotated to rotate the threaded rod upward, thereby moving the rotating disk away from the lower portion of the U-shaped insert, and the U-shaped insert can be rotated. After adjusting the direction of the instrument, the rotating disk is rotated in the opposite direction to rotate the threaded rod downward, so that the rotating disk contacts the lower portion of the U-shaped insert, thereby fixing the U-shaped insert.

[0015] Furthermore, the bracket assembly includes an arc-shaped plate, a fixing ring, and a T-shaped bolt. The fixing ring is arranged at one end of the arc-shaped plate, and the T-shaped bolt is arranged at the upper middle part of the other end of the arc-shaped plate.

[0016] Furthermore, a soft cushion is provided under the curved plate.

[0017] The curved plate fits the shape of the operator's arm better, and the soft padding further increases the operator's comfort.

[0018] Furthermore, the strap assembly includes a strap, an elastic band, and a ring sleeve, which are arranged in sequence, and one end of the strap away from the ring sleeve is connected to one end of the arc plate away from the fixing ring.

[0019] Furthermore, a plurality of evenly distributed silicone strips are provided on the inner side of the strap, a Velcro hook surface is provided on the outer end of the strap close to the fixing ring, and a Velcro fleece surface is provided on the outer end of the strap away from the fixing ring.

[0020] Furthermore, the inner diameter of the ring sleeve corresponds to the T-bolt.

[0021] The strap passes through the fixed ring and is adjusted according to the thickness of the operator's arm, and is bonded and fixed by the Velcro hook and Velcro fleece. Pull the elastic band to make the ring sleeve fit over the T-bolt to further fix the strap and prevent the adhesive surfaces of the Velcro hook and Velcro fleece from tearing. The setting of the silicone strip not only increases the comfort of the operator, but also the silicone strip on the surface of the strap can softly contact the operator's arm, allowing the sweat formed to flow out from the gap, preventing the strap from sliding on the operator's arm after sweat forms between the strap and the arm, causing the instrument to shake and affecting the measurement work.

[0022] Compared with the prior art, the portable instrument fixing device described in the present invention has the following advantages:

[0023] (1) The plug-in assembly of the present invention enables the instrument bonded to the socket to be plugged into the U-shaped plug-in plate, and is fixed in position by two limiting assemblies, making installation and disassembly convenient.

[0024] (2) The rotary adjustment assembly described in the present invention can realize the rotation and fixation of the U-shaped plug plate by rotating the rotary disk, so that the instrument plugged into the U-shaped plug plate can adjust the direction, which is convenient for the operator to operate the instrument.

[0025] (3) The strap assembly described in the present invention can adjust the circumference of the strap through the Velcro hook surface and the Velcro fleece surface, so as to adapt to the thickness of the arms of different operators. The setting of the elastic belt and the loop can further fix the strap to prevent the adhesive surface of the Velcro hook surface and the Velcro fleece surface from being torn apart. The silicone strip can softly contact the operator's arm to allow the sweat formed to flow out from the gap, thereby preventing the strap from sliding on the operator's arm after sweat is formed between the strap and the arm, causing the instrument to shake and affecting the measurement work.
