Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The portable bracket for the special equipment detection instrument shown in the attached drawing comprises two pairs of unit rod sets 4 with the same structure and a supporting plate 3 lifted by the two pairs of unit rod sets; each pair of unit rod groups comprises a first supporting rod 1 and a second supporting rod 2, and the upper end of the first supporting rod 1 is hinged with the upper end of the second supporting rod 2; two pairs of unit bar sets 4 are arranged on both sides of the bearing plate 3. The two sides of the bearing plate 3 are respectively in damping fit with the second support rods 2 in the two pairs of unit rod groups (the damping fit is that the bearing plate is hinged with the support rods through hinge shafts, meanwhile, friction pieces such as rubber are arranged at the hinged parts, so that the rotation between the bearing plate and the support rods is subjected to certain resistance, and the device belongs to the prior art), and therefore the overturning motion relative to the unit rod groups is realized. In each pair of unit rod groups, an elastic cross rod 5 is arranged between the lower end of the first support rod 1 and the lower end of the second support rod 2; the elastic cross rod can freely and elastically stretch along the length direction of the elastic cross rod (as shown in figure 3; an arrow above the bearing plate in the figure represents pressure applied by an instrument), when the bearing plate 3 is pressed, the first supporting rod 1 and the second supporting rod 2 are correspondingly opened, an included angle between the first supporting rod and the second supporting rod is increased, and at the moment, the elastic cross rod 5 is extended in an adaptive manner (as shown by a double-direction arrow in the figure), so that a new relatively stable triangular structure is formed. When the support is not used, the elastic cross rod can be detached from the unit rod group, and the first support rod and the second support rod are closed around the hinged part, so that the occupied space of the unit rod group is greatly reduced, and the support is more convenient to grasp and carry than a regular strip-shaped structure; and the unit rod group and the bearing plate can be disassembled.

The elastic cross bar 5 comprises a spring 51 and a ring piece 52, and the ring piece 52 is connected and arranged at two ends of the spring 51; in each pair of unit rod sets, a first limiting rod 11 is arranged on the first support rod 1 (preferably at the lower half part of the support rod), and a second limiting rod 21 is arranged on the second support rod 2 (preferably at the lower half part of the support rod); the ring pieces 52 at the two ends of the spring 51 are respectively in nested fit with the first limiting rod and the second limiting rod (the heads of the first limiting rod and the second limiting rod are bosses which are larger than the inner hole of the ring piece), and the nested fit mode is very convenient to disassemble and assemble and is suitable for the detection of special equipment and the work with strong maneuverability; meanwhile, the two limiting rods can mutually form a mutually-drawn state, so that the problem that the ring piece and the limiting rods slip off is solved.

As shown in fig. 1, each elastic crossbar 5 further comprises a sleeve 53; the sleeve is sleeved outside the spring 51 in a matching manner; the middle section part in the sleeve is fixedly connected with the middle section part of the spring 51; the length of the two ends of the spring in a natural state is smaller than that of the sleeve 53 at the corresponding end, and the outer diameter of the ring piece 52 is larger than the inner diameter of the sleeve; when the elastic cross bar 5 is not in use, the spring 51 is in a retraction state, and the ring piece 52 is subjected to a pulling force pointing to the center of the sleeve, so that the mouths at two ends of the sleeve are blocked; thereby at the accomodate in-process of elasticity horizontal pole, showing and reducing the dust and the steam that get into the sleeve inside, delay the corruption of spring, increase of service life.

In the two pairs of unit rod groups, a first roller piece 61 is rotatably arranged between the bottom ends of the two first supporting rods 1, and a second roller piece 62 is rotatably arranged between the bottom ends of the two second supporting rods 2 (the first roller piece and the second roller piece both comprise roller shafts and sleeves rotatably sleeved on the roller shafts); a plurality of rolling stopping grooves 601 are formed in the outer circumferential surfaces of the first roller piece and the second roller piece along the length direction of the first roller piece and the second roller piece; the roller structure can adapt to the opening and closing actions of the unit rod group 4 after being pressed by utilizing the rotation of the roller structure, and can adapt to rugged terrains by utilizing rolling compared with a foot pad type bearing part, so that the situation of blocking and clamping in the stretching process is obviously reduced; the rolling stop groove 601 can provide a stable bearing surface for the bottom of the roller structure, so that the roller structure can stop sliding after the unit rod group 4 is adjusted (fig. 3 shows a schematic view of the stable bearing state of the first roller element 61 and the second roller element 62 with the bottom field surface).

As shown in fig. 2, a positioning pin hole 31 is formed in the side surface of the backup plate 3; the unit rod group 4 is provided with a positioning hole 32; the positioning hole 32 corresponds to the swing path position of the positioning pin hole 31; the positioning pin hole 31 and the positioning hole 32 are internally embedded with a pin; when instruments such as an infrared distance meter and the like need to be flexibly adjusted in use, stable pitching control can be realized only by means of the rotary damping between the bearing plate 3 and the unit rod group 4, and the operation is convenient and fast; when the instrument such as a horizontal calibration device and the like needs a relatively fixed use environment, the pin column can be matched with the positioning hole 32 and the positioning pin hole 31 to restrain the rotational freedom degree of the bearing plate 3.

As shown in fig. 1, the backup plate 3 includes a plate body 301; the plate 301 is fixedly connected with the rotating pieces 309 at two sides (the edge of the plate can be inserted into the slot of the rotating piece first, and then the plate and the rotating pieces are connected and fixed through the fastening piece); the rotary connection between the rotating member 309 and the second support rod 2 is a conventional structure in the art and will not be described herein. An anti-skid rubber pad 302 is embedded in the gravity center of the top of the plate body 301, and instruments and equipment needing to be horizontally placed can realize position stability by utilizing the friction force between the rubber pad 302 and the bottom of the instruments and equipment; the plate body 301 is also provided with a mounting hole 303; a plurality of mounting holes 303 are distributed around the anti-skid rubber mat 302; for the instrument equipment needing pitch adjustment, the instrument equipment can be connected with the bottom of the equipment through a fastening bolt or an adhesive piece matched in the mounting hole 303.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
