Description

Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to a wearable laser sampling template. Background Art

[0002] A sampling template is a commonly used test instrument for sampling the surface of an object during the detection process in the fields of medical and health, food and drugs, environmental protection, public places, etc. When in use, a sterilized sampling template with a size of 5 cm × 5 cm or 10 cm × 10 cm needs to be placed flat on the surface of the item to be inspected, and then a cotton swab dipped in the corresponding sterile eluent is used to evenly wipe back and forth within the sampling template for sampling.

[0003] After the existing sampling plate is used once, it needs to be cleaned and disinfected again. For each sampling, the sampling plate needs to be replaced once, and the process is cumbersome. Moreover, a laser projection sampling template with the publication number of CN212567979U discloses a technology that is portable and does not require the use of a physical sampling plate.

[0004] In the process of using the above existing technologies, it is difficult to make appropriate adjustments according to the spacing in the actual use scenario. After the height of the laser emission position is easily changed, the laser projection area will change, affecting the area size accuracy of the sampling area. Summary of the Utility Model

[0005] Therefore, the utility model provides a wearable laser sampling template to solve the above problems in the existing technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

A strap is installed at the outer end of the installation block for wearing.

[0009] A central control mechanism is installed inside the installation housing, and a laser projection lamp is installed on the side of the central control mechanism away from the magnetic attraction block for laser projection. A distance measurement mechanism is arranged on one side of the laser projection lamp for distance measurement, and a covering area adjustment mechanism is installed outside the laser projection lamp for restricting the laser projection area.

[0010] Furthermore, the installation block and the installation housing are rotationally connected.

[0011] Furthermore, the covering area adjusting mechanism includes a mounting base. An engaging wheel is arranged inside the mounting base, and the engaging wheel is rotatably connected to the mounting housing. One side of the engaging wheel is meshed with a driving wheel for driving the engaging wheel to rotate.

[0012] Furthermore, a limiting frame is rotatably connected to the side of the engaging wheel away from the mounting housing, and a covering plate is slidably mounted inside the limiting frame.

[0013] Furthermore, there are 4 groups of covering plates arranged in the mounting base, and the middle parts of the covering plates are combined to form a square cross-section.

[0014] Furthermore, the longitudinal section of the covering plate is in a "Ji" shape.

[0015] Furthermore, a groove-shaped structure corresponding to the convex structure inside the limiting frame is also formed on the outer surface of the covering plate.

[0016] Furthermore, a switch button is also installed on one side of the mounting housing for starting and controlling the central control mechanism.

[0017] Furthermore, a buzzer is also arranged inside the central control mechanism for height prompting.

Specific embodiments

[0025] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 4 shown, a wearable laser sampling template in the first aspect embodiment of the present utility model includes a mounting housing 1. A magnetic attraction block 2 is installed on the outer surface of the mounting housing 1, and an iron block corresponding to the magnetic attraction block 2 is arranged inside a mounting block 4, which is used to generate a magnetic attraction effect with the magnetic attraction block 2. A strap 3 is installed at the outer end of the mounting block 4 for wearing on the user's head or arm. After the double-strand strap 3 is installed on the arm, the mounting housing 1 can be prevented from deflecting;

[0027] The mounting block 4 is rotatably connected to the mounting housing 1, so that after the strap 3 installed in the mounting block 4 is worn on the user's head or arm alone, the turning direction of the mounting housing 1 can be adjusted.

[0028] A central control mechanism 5 is installed inside the mounting housing 1. A computer program is incorporated in the central control mechanism 5 for controlling the start of the covering area adjustment mechanism 8. A laser projection lamp 7 is installed on the side of the central control mechanism 5 away from the magnetic attraction block 2 for laser projection. A ranging mechanism 6 is arranged on one side of the laser projection lamp 7. The ranging mechanism 6 is specifically a small laser rangefinder for ranging. A covering area adjustment mechanism 8 is installed outside the laser projection lamp 7 for restricting the laser projection area. Among them, the covering area adjustment mechanism 8 includes a mounting base 801. A connecting wheel 802 is arranged inside the mounting base 801, and the connecting wheel 802 is rotatably connected to the mounting housing 1. A driving wheel 805 is meshed and connected to one side of the connecting wheel 802 for driving the connecting wheel 802 to rotate. A limiting frame 803 is rotatably connected to the side of the connecting wheel 802 away from the mounting housing 1. A covering plate 804 is slidably installed inside the limiting frame 803. Four groups of covering plates 804 are arranged in the mounting base 801, and the middle parts of the covering plates 804 are combined to form a square cross-section, so as to restrict the shape of the laser emitted by the laser projection lamp 7 to be square;

[0029] Specifically, after the user wears it, the distance measuring mechanism 6 measures the distance between the mounting housing 1 and the sampling area. After obtaining the distance data feedback, the central control mechanism 5 controls the driving wheel 805 to start, causing the connecting wheel 802 to rotate. After the connecting wheel 802 rotates, it drives the limit frame 803 rotatably connected to the surface of the connecting wheel 802 to move. Since both ends of the shielding cover plate 804 are constrained to slide within the mounting seat 801, the limit frame 803 drives the shielding cover plate 804 to move without deflection, thereby changing the shielding area of the shielding cover plate 804 for the laser projection lamp 7, so that the area of the laser projection lamp 7 projected on the sampling area can be controlled;

[0030] A buzzer is also provided inside the central control mechanism 5 for height prompting;

[0031] In a specific embodiment, when the distance measuring mechanism 6 detects that the mounting housing 1 reaches a certain height within the central control mechanism 5, the buzzer emits an alarm to prompt that this height is suitable for generating the sampling area, so that the user stops moving the arm when reaching this height, and the laser projection lamp 7 is started and projects the sampling area.

[0032] The longitudinal section of the shielding cover plate 804 is in a "Ji" shape, so that the convex part in the middle of the shielding cover plate 804 can avoid conflicts with other shielding cover plates 804 and the limit frame 803;

[0033] The outer surface of the shielding cover plate 804 is also provided with a groove-shaped structure corresponding to the convex structure inside the limit frame 803, thereby reducing the protruding height of the limit frame 803, thereby reducing the convex height in the middle of the shielding cover plate 804 and reducing the material consumption.

[0034] A switch button 9 is also installed on one side of the mounting housing 1 for starting control of the central control mechanism 5.
