DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative effort belong to the scope of protection of the present application.

[0026] Embodiment: refer to Figures 1-4The shown one kind is high-value special RFID identification handheld device of consumables, including shell 1, and identification unit 2, display screen 3 and handle 4 are installed at the front end, upper end and lower end of shell 1 respectively, control button 5 is installed on the side of the upper end of shell 1 away from identification unit 2, identification button 6 is installed on the side of handle 4 close to identification unit 2, above-mentioned identification unit 2, display screen 3, control button 5 and identification button 6 all adopt conventional relevant components in prior art, and all are electrically connected with built-in processor, wherein, identification unit 2 is used to identify the label on medical consumables, belongs to prior art, not described here, in addition, the RFID identification handheld device also includes other components on the existing RFID identification handheld device, such as charging interface, data transmission interface, data storage, battery etc. (not shown in the figure), since RFID identification, data transmission, output storage etc. of RFID identification handheld device itself all belong to prior art, it is considered to be disclosed, so it is not described here.

[0027] The end of identification unit 2 away from shell 1 and the end of handle 4 away from shell 1 are all sleeved with buffer pad 16, which can play a certain buffering effect when resting and is not easy to be knocked.

[0028] Wherein, identification unit 2 is rotatably installed at the front end of shell 1 through pivot 7, damping mechanism is arranged between pivot 7 and shell 1, after rotating identification unit 2, the included angle between identification unit 2 and shell 1 is kept fixed under the action of damping mechanism, when using, it is convenient to adjust the included angle between identification unit 2 and shell 1 according to the needs of the user himself, especially when identifying medical consumable labels of fixed angle in batches, the included angle between identification unit 2 and shell 1 can be adjusted to the most comfortable state for the user to hold and operate, which is more convenient to use.

[0029] Regarding the damping mechanism, specifically, as shown in the figure, Figure 3 The damping mechanism includes limiting tooth block 8, protective shell cover 9, fixed block 10, tension spring 11 and damping block 12, more specifically, a plurality of limiting tooth blocks 8 are arranged, and the plurality of limiting tooth blocks 8 are equidistantly fixed to the circumferential side of one end of pivot 7, protective shell cover 9 is slidingly installed at the side end of shell 1, fixed block 10 is fixed to the side end of shell 1, tension spring 11 is fixed between protective shell cover 9 and fixed block 10, damping block 12 is fixed to the inner wall on the side of protective shell cover 9 away from fixed block 10, the distance between adjacent two limiting tooth blocks 8 is greater than the thickness of damping block 12.

[0030] When it is necessary to adjust the included angle between the identification unit 2 and the shell 1, the user can manually force the identification unit 2 to rotate, so that the limiting tooth block 8 can extrude the damping block 12 with a force sufficient to stretch the tension spring 11, and then the damping block 12 moves away from the limiting tooth block 8, at this time the identification unit 2 can rotate with the rotating shaft 7, and after rotating to the appropriate angle, the identification unit 2 is released, at this time the damping block 12 moves close to the limiting tooth block 8 under the restoring action of the tension spring 11, and the limiting tooth block 8 is limited, so that the included angle between the identification unit 2 and the shell 1 is fixed. In addition, the operator can also manually push the protective shell cover 9 away from the fixed block 10, so that the damping block 12 moves away from the limiting tooth block 8, at this time the identification unit 2 can be easily rotated to the required angle, and then the protective shell cover 9 is released, and the damping block 12 moves close to the limiting tooth block 8 under the restoring action of the tension spring 11, and the limiting tooth block 8 is limited. In order to facilitate the operator to push the protective shell cover 9, a boss 14 is integrally arranged on the outer wall of the side of the protective shell cover 9 away from the shell 1.

[0031] It needs to be further explained that compared with the fixed connection mode of the identification unit 2 and the shell 1 in the prior art, the above limiting tooth block 8, protective shell cover 9, fixed block 10, tension spring 11 and damping block 12 are cooperatively arranged, so that the identification unit 2 has a certain buffering effect when it is subjected to collision impact from the upper and lower sides, and the identification unit 2 can be better protected. In addition, based on the above two adjustment modes, the latter adjustment mode can better protect the limiting tooth block 8 and the damping block 12, so that they are not easy to be broken due to frequent adjustment.

[0032] The damping mechanism further comprises a telescopic rod 13 fixed between the protective shell cover 9 and the fixed block 10. The telescopic rod 13 can be a pipe with two sections of different diameters slidingly sleeved with each other, and the two sections of the pipe are fixed with the protective shell cover 9 and the fixed block 10 respectively.

[0033] The bottom end of the shell 1 is fixed with a semi-open protective cover 15, and the open side of the semi-open protective cover 15 faces the side of the handle 4. The semi-open protective cover 15 can protect the hand holding the handle 4 of the user, and can avoid the hand contacting the medical consumables, especially some corrosive medical consumables.

[0034] In addition, an auxiliary illuminating lamp (not shown in the figure) is installed on the identification end face of the identification unit 2, which can be turned on for auxiliary illumination when used in an environment with insufficient light.

[0035] The utility model discloses working principle: when needing to adjust the included angle between identification unit 2 and shell 1, the user can manually force the identification unit 2, make the force of extruding damping block 12 of limiting tooth block 8 enough to make the tensile spring 11 stretch, and damping block 12 is far away from limiting tooth block 8, identification unit 2 can rotate with pivot 7 at present, and identification unit 2 is loosened after rotating to the appropriate angle, and damping block 12 is close to limiting tooth block 8 under the reset action of tensile spring 11 at present, and limiting tooth block 8 is positioned, thereby making the included angle between identification unit 2 and shell 1 keep fixed;

[0036] In addition, the operator can also manually push the protective shell cover 9 towards the side far away from fixed block 10, so that the damping block 12 is far away from the limiting tooth block 8, at this time, the identification unit 2 can be easily rotated to the required angle, and then the protective shell cover 9 is loosened, and the damping block 12 is close to the limiting tooth block 8 under the reset action of the tensile spring 11, and the limiting tooth block 8 is positioned.

[0037] Finally, it should be pointed out that: the above-mentioned only for the preferred embodiment of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
