Description

Technical Field

[0001] The utility model relates to the technical field of occupational health detection, in particular to a sample constant temperature storage device for occupational health detection. Background Art

[0002] Occupational health monitoring refers to evaluating the impact and extent of occupational hazards on the health of those exposed to them through various examinations and analyses, understanding the health status of employees, and promptly discovering signs of health damage so that appropriate preventive measures can be taken to prevent the occurrence and development of diseases caused by harmful factors.

[0003] like Figure 4 As shown, it is a previous generation of constant temperature preservation device for occupational health testing samples, and its main function is to centrally store the collected samples of different types and provide a constant temperature storage environment for the samples to facilitate subsequent testing operations on the samples. However, the previous generation of constant temperature preservation device for samples has the following shortcomings in actual use: since the support blocks are equidistantly fixed on the inner side of the box, and the material racks are placed on the inner side of the box through the support blocks, the spacing between multiple material racks is relatively fixed and difficult to adjust. If a sample with a higher height needs to be stored, one of the material racks needs to be pulled out. By using fewer material racks, the number of samples that can be stored in the box will be directly reduced.

[0004] In view of this, it is particularly important to design and manufacture a sample constant temperature storage device that can realize convenient adjustment of the longitudinal spacing between the material racks and facilitate the adjustment and storage of different types of samples in the actual occupational health testing process. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the spacing between multiple material storage racks in traditional constant temperature storage devices for occupational health testing is fixed, which makes it inconvenient to adjust and store different types of samples during actual use, and to propose a constant temperature storage device for samples for occupational health testing.

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

[0007] A constant temperature storage device for samples used for occupational health testing, comprising a box body with an open front end, a visible box door rotatably installed at the front end of the box body, a lower circulation fan installed at the bottom of the inner side of the box body, an upper circulation fan installed at the top of the inner side of the box body, an electric heating lamp installed at the top of the inner side of the box body and located at the periphery of the upper circulation fan, support brackets arranged on the left and right sides of the interior of the box body, and a material placement grid between the upper ends of the two support brackets, two guide slides distributed vertically and parallelly are symmetrically fixedly connected to the left and right side surfaces of the interior of the box body, the support bracket is movably installed between the two guide slides, and a locking mechanism is arranged between the support bracket and the two guide slides for conveniently locking the position of the support bracket after vertical adjustment.

[0009] The locking mechanism includes a T-shaped slide groove opened in the middle of the lower end of the support bracket, two L-shaped sliders symmetrically and movably installed on the inner side of the T-shaped slide groove, a locking column fixed on the horizontal end of the L-shaped slider and laterally passing through the guide slide bar, and a plurality of locking holes opened on the guide slide bar and corresponding to the locking column.

[0010] As a further description of the above technical solution:

[0011] The vertical ends of the two L-shaped sliding blocks are fixedly connected with laterally distributed limiting protrusions, and a spiral extrusion spring is installed between the limiting protrusions of the two L-shaped sliding blocks.

[0012] As a further description of the above technical solution:

[0013] An anti-deviation portion is arranged between the material placing grid frame and the supporting bracket to limit the multi-directional deviation movement of the material placing grid frame above the supporting bracket.

[0014] As a further description of the above technical solution:

[0015] The anti-deviation part includes a limiting column fixed on the four corners of the lower end of the material placing grid and penetrating downwardly through the supporting block, and a limiting hole opened on the supporting block and corresponding to the limiting column.

[0016] As a further description of the above technical solution:

[0017] The anti-bias part also includes a second magnetic sheet symmetrically fixed at the middle of the left and right ends of the material placing grid and a first magnetic sheet fixed at the middle of the upper end of the supporting block and magnetically attached to the second magnetic sheet.

[0018] As a further description of the above technical solution:

[0019] An electric controller is installed at the top of the front end of the box body, and the output end of the electric controller is electrically connected to the input ends of the lower circulation fan, the upper circulation fan and the electric heating lamp respectively.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Please refer to 1-3. The utility model provides a technical solution: a constant temperature storage device for samples for occupational health testing, comprising a box body 1 with an open front end, a visible box door 101 rotatably installed at the front end of the box body 1, a lower circulation fan 102 installed at the bottom of the inner side of the box body 1, an upper circulation fan 103 installed at the top of the inner side of the box body 1, an electric heating lamp 104 installed at the top of the inner side of the box body 1 and located at the periphery of the upper circulation fan 103, support brackets 2 arranged on the left and right sides of the interior of the box body 1 and a material placing grid 3 between the upper ends of the two support brackets 2, two vertically parallel guide slides 4 are symmetrically fixedly connected to the left and right side surfaces of the interior of the box body 1, the support bracket 2 is movably installed between the two guide slides 4, and a locking mechanism is provided between the support bracket 2 and the two guide slides 4 for conveniently locking the position of the support bracket 2 after vertical adjustment.

[0031] Specifically, Figure 1-3 As shown, the locking mechanism includes a T-shaped slot 201 opened in the middle of the lower end of the support bracket 2, two L-shaped sliders 5 symmetrically and movably installed on the inner side of the T-shaped slot 201, a locking column 501 fixed on the horizontal end of the L-shaped slider 5 and transversely passing through the guide slide 4, and a plurality of locking holes 401 opened on the guide slide 4 and corresponding to the locking column 501. When the locking column 501 on the L-shaped slider 5 slides horizontally into the locking hole 401 on the guide slide 4, the support bracket 2 can be limited and locked on the guide slide 4.

[0032] Among them, the vertical ends of the two L-shaped sliders 5 are fixedly connected with laterally distributed limiting protrusions 502, and a spiral extrusion spring 6 is installed between the limiting protrusions 502 of the two L-shaped sliders 5. The spiral extrusion spring 6 can generate an outward elastic extrusion force under normal conditions, so that the two L-shaped sliders 5 can stably abut the T-shaped slide groove 201 outward, so that the locking column 501 on the L-shaped slider 5 can be stably locked in the locking hole 401 of the guide slide 4. Among them, the setting of the limiting protrusion 502 can improve the stability of the spiral extrusion spring 6 installed between the two L-shaped sliders 5.

[0033] Specifically, Figure 1-3 As shown, an anti-bias part for limiting the multi-directional deviation movement of the material placing grid frame 3 above the support bracket 2 is arranged between the material placing grid frame 3 and the support bracket 2, and the anti-bias part includes a limiting column 301 fixed at the four corners of the lower end of the material placing grid frame 3 and penetrating the support bracket 2 downward, and a limiting hole 202 opened on the support bracket 2 and corresponding to the limiting column 301. When the limiting column 301 on the material placing grid frame 3 is inserted into the limiting hole 202 of the support bracket 2, the freedom of the material placing grid frame 3 in the X-axis and Y-axis directions between the two support brackets 2 can be limited, thereby reducing the material placing grid frame 3 between the box body 1 and the two The anti-bias part also includes a second magnetic sheet 302 symmetrically fixed at the middle of the left and right ends of the material rack 3 and a first magnetic sheet 203 fixed at the middle of the upper end of the support bracket 2 and magnetically bonded to the second magnetic sheet 302. When the material rack 3 is installed on the two support brackets 2, the second magnetic sheet 302 on the material rack 3 will be magnetically bonded to the first magnetic sheet 203 on the support bracket 2, which can apply a downward magnetic force to the material rack 3, and cooperate with the self-weight of the upper material rack 3 to reduce the displacement movement of the material rack 3 along the Z-axis direction.

[0034] Specifically, Figure 1 and Figure 2 As shown, an electric controller 105 is installed at the top of the front end of the box 1, and the output end of the electric controller 105 is electrically connected to the input ends of the lower circulation fan 102, the upper circulation fan 103 and the electric heating lamp 104 respectively. The setting of the electric controller 105 facilitates the operator to control the power supply of the lower circulation fan 102, the upper circulation fan 103 and the electric heating lamp 104 and adjust the working parameters.

[0035] Working principle: Under normal conditions, under the action of the elastic force of the spiral extrusion spring 6, the two L-shaped sliders 5 will be squeezed and fitted with the ends of the T-shaped slide groove 201. At this time, the locking column 501 on the L-shaped slider 5 will be inserted into the locking hole 401 at the specified position on the guide slide 4. At this time, the support bracket 2 will be stably locked between the box body 1 and the two guide slides 4 as a whole, and the material placement grid 3 can be placed between the upper ends of the two support brackets 2 through the comprehensive limit of the limit column 301 and the second magnetic suction piece 302. When it is necessary to adjust the spacing of the material placement grid 3, the operator can hold and press the two L-shaped sliders 5 on the support bracket 2 at the specified position inward, and the two L-shaped sliders 5 can be in the T-shaped slide groove 201. Move inward and squeeze the spiral extrusion spring 6. At this time, the locking columns 501 on the two L-shaped sliders 5 can slide away from the locking holes 401 on the two guide slides 4 respectively. At this time, the locking state between the support bracket 2 and the guide slide 4 is released, and the support bracket 2 can be vertically slid between the two guide slides 4. After adjusting to the appropriate position, the two L-shaped sliders 5 can be released. At this time, under the action of the elastic force of the spiral extrusion spring 6, the locking columns 501 on the two L-shaped sliders 5 can bounce into the locking holes 401 at the specified positions on the guide slide 4, thereby locking and fixing the support bracket 2 in the adjusted position, thereby completing the convenient adjustment operation of the spacing between the material loading grids 3.
