Description

Technical Field

[0001] The present invention relates to a bracket, and more particularly, to a bracket for a tester, which can place a tester and a chamber so that a user can easily inject liquid into the chamber and insert the chamber filled with a liquid material sample into the tester. Background Art

[0002] First of all, liquid substances in the following text include various liquid samples contained in the human body, such as saliva, blood, semen, sweat, urine, tears, etc., and a broader range also includes various types of similar liquid substances, including organic and inorganic compounds used in scientific research such as medicine, biology, water quality, and environment.

[0003] Generally speaking, a liquid material inspection device (hereinafter referred to as a "tester") for inspecting liquid materials has been developed and provided. Among these existing testers, as described in Granted Patent No. 10-2288223 and Granted Patent No. 10-2333043, there is a tester that uses a chamber filled with a liquid material sample to receive the liquid material sample. The term "chamber" is a general term for all types of devices that are filled with a liquid material sample and inserted into the tester to supply the liquid material sample.

[0004] The typical method for using a chamber in such a tester is for the user to place the chamber on a table or desk, then supply a liquid sample to the chamber using a liquid sample supply device. Since the chamber is approximately 1 mm thick, the user holds the chamber by hand while supplying the liquid sample.

[0005] Afterwards, the user places the tester back on a table or a stand and then holds the chamber containing the sample by hand or directly holds the chamber and inserts it into the tester.

[0006] However, during this process, since the user holds the chamber or tester by hand while performing the operation, it brings inconvenience to the user. Depending on the situation, accidents may occur in which the chamber or tester is damaged due to mistakes such as not holding the chamber properly or dropping the tester.

[0007] In addition, when a chamber-based tester is loaded with a liquid material sample, the user needs to observe the liquid material sample loaded into the tester through the camera lens of the mobile phone, but it is inconvenient to closely contact the tester with the mobile phone in the air or on a table to observe. Summary of the Invention

[0053] In the present application, it is understood that the terms "include" or "have" or the like are intended to designate the existence of the features, numbers, steps, actions, constituent elements, parts, or combinations thereof described in the specification, but do not preclude the existence or additional possibility of one or more other features, numbers, steps, actions, constituent elements, parts, or combinations thereof.

[0054] Hereinafter, the present application will be described with reference to the accompanying drawings.

[0055] Figure 1 is a top perspective view of a stand for a tester according to an embodiment of the present application, Figure 2 is a rear perspective view of a stand for a tester according to an embodiment of the present application, Figure 3 is a perspective view showing a height difference between a chamber region and a tester region in a stand for a tester according to an embodiment of the present application.

[0056] Referring to Figures 1 to 3 , a stand for a tester 100 according to an embodiment of the present application can include a main body 110, a chamber placement portion 120, a device placement portion 130, and a height adjustment portion 140.

[0057] The main body 110 is manufactured to be horizontal when placed on the ground or a flat object (i.e., a desk, a table, or the like) and to have a thickness (i.e., a height) so as to have a space in which a tester is placed and can be vertically moved. The thickness can be manufactured to have a length such that a part of the height adjustment portion 140 does not touch the ground or the object on which the stand 100 is placed when the height adjustment portion 140 is vertically lowered, or the cup 40 mounted on the back does not touch the ground or the object when the cup 40 is mounted on the back (refer to Figure 6 ).

[0058] The overall shape of the main body 110 can be manufactured as a hexahedron in consideration of the placement of the mobile phone on the upper surface, but is not limited thereto. In order to place the mobile phone 400 (refer to Figure 9 and Figure 10) is arranged on the upper surface of the main body 110 in parallel with the placed tester, and a mobile phone placement area 30 is formed on the upper surface to abut against the mobile phone, and the mobile phone placement area 30 is made into a flat shape.

[0059] The upper surface of the main body 110 is formed with a chamber operation area 10 and a device operation area 20. The chamber operation area 10 is for the user to place the chamber 200 (refer to Figure 7 ) area, which is used to perform the operation of injecting the liquid material sample into the chamber, and the device operation area 20 is used to place the tester 300 (refer to Figure 7 ) area and insert the chamber 200 into the tester 300.

[0060] The chamber operation area 10 is formed in an intaglio manner on the upper surface of the main body 110 and includes an area where the chamber placement portion 120 is formed. The area is made to have a wider area than the chamber placement portion 120 to facilitate the user to place the chamber 200 by hand or inject the liquid material sample into the chamber 200 while holding the chamber 200.

[0061] The chamber operation area 10 can be formed in a groove shape so as to be located below the mobile phone placement area 30. In this case, the groove can have a depth of length L1. Furthermore, at least one inner side of the chamber operation area 10 can be open to the outside, allowing the user's hand to freely move toward the chamber placement portion 120. In this case, the open inner side of the chamber operation area 10 can include one of the two side surfaces along the length direction of the main body 110.

[0062] The device operation area 20 is formed in an intaglio manner on the upper surface of the main body 110 and includes an area where the device placement portion 130 is formed, and is made to have an area that is more spacious than the device placement portion 130, so that the user can place the tester 300 by hand or insert the tester 300 into the chamber 200 while holding it.

[0063] The device operating area 20 may be formed in a groove shape to be located lower than the mobile phone placement area 30. In this case, considering that the thickness of the tester 300 is thicker than the thickness of the chamber 200, the depth of the groove may have a length L2 that is longer than the length L1. Of course, depending on the situation, the length L1 may be the same as or longer than L2.

[0064] Furthermore, at least one inner side of the device operation area 20 is open to the outside so that the user's hand can freely move toward the chamber placement portion 120 and insert the chamber 200 into the insertion port 320 of the tester 300 (see FIG. Figure 7At this time, the inner side of the open device operation area 20 may include one of the two side surfaces in the length direction of the main body 110, and may also include a side surface in the length direction close to the device operation area 20 or the other of the two side surfaces in the length direction of the main body 110.

[0065] On the upper surface of the main body 110, the number "2" may be formed inside or near the chamber operation area 10, and the number "3" may be formed inside or near the device operation area 20. The numbers "2" and "3" represent the operation sequence, such as Figure 6 As shown, the number “1” may be formed in the cup 40 .

[0066] In addition, an anti-slip pad 150 may be formed on the main body 110 to prevent the mobile phone 400 from sliding when the mobile phone 400 is placed. Figure 5 The anti-skid pad portion 150 may include an anti-skid pad portion 151 and a pad groove 152 to which the anti-skid pad portion 151 is mounted or attached. On the other hand, the main body 110 may be formed with a leg-shaped support portion 111 protruding from each corner of the rear surface toward the lower side.

[0067] The chamber placement portion 120 is formed in the chamber working area 10 and is used to place the chamber 200. The chamber placement portion 120 may include a chamber placement area 121, a fixing frame 122 and a locking groove 123.

[0068] The chamber placement area 121 can be manufactured in the same shape as the outer shape of the chamber 200, or at least in the same shape as the outer shape of the portion of the chamber 200 that contains the liquid material sample. In each of the drawings of the present invention, the chamber placement area 121 is shown as being manufactured in the same shape as the outer shape of the remaining portion of the chamber 200 except for a portion of the handle portion.

[0069] The chamber placement area 121 may be formed to protrude from the bottom surface of the chamber operation area 10. In this case, the maximum protrusion position may be the same as or lower than the position of the mobile phone placement area 30. The entire chamber placement area 121 may be painted with a first color other than white, or attached with a tape or film of the first color. The reason for applying the first color to the chamber placement area 121 is that when the main body 110 is white, the chamber 200 may be difficult to identify due to its transparent color.

[0070] To secure the chamber 200 placed in the chamber placement area 121, the fixing frame 122 is formed to protrude at a predetermined height along the edge of the chamber placement area 121. The fixing frame 122 is preferably not formed on at least one of the two longitudinal surfaces of the chamber placement area 121 to facilitate placement of the chamber 200 in the chamber placement area 121. Alternatively, the fixing frame 122 may protrude intermittently along the edge of the chamber placement area 121 to create spaces between adjacent protruding portions.

[0071] The engaging groove 123 is formed to correspond to the protrusion 210 formed on the back of the chamber 200 so that the protrusion 210 formed on the back of the chamber 200 fits in the chamber 200, allowing the user to confirm that the chamber 200 is completely placed in the chamber placement area 121 and secure the chamber 200 in the chamber placement area 121. Depending on circumstances, the engaging groove 123 may be omitted.

[0072] The device placement portion 130 is formed in the device operation area 20 and is configured to accommodate the tester 300 and the height adjustment portion 140. The device placement portion 130 may be configured to allow the tester 300 to be inserted or removed, or may be integrally fixed to the tester 300.

[0073] Such a device placement portion 130 may include a device insertion groove 131 , a fastening insertion groove 132 , and a leg hole 133 .

[0074] The device insertion groove 131 is a groove for inserting and installing a part of the tester 300 or fixing the tester 300 integrally therewith, and is formed into the same shape as the outer shape of the tester 300 .

[0075] Furthermore, the depth of the device insertion groove 131 is made such that the insertion port 320 of the inserted or integrated tester 300 is exposed to the outside, and the back side of the inserted tester 300 (i.e., the back side having the lens portion 310 (see FIG. 1 ) is formed). Figure 7 ) reaches the position of the mobile phone placement area 30, or is located at a position higher than the position of the mobile phone placement area 30 by a set length. In the present invention, a circular tester 300 is taken as an example, so the shape of the device insertion groove 131 is shown as a circular groove.

[0076] The fastening insertion groove 132 is formed so that the height adjustment portion 140 can be inserted and fixed to the device insertion groove 131, and is formed to protrude from a portion of the inner bottom surface of the device insertion groove 131 toward the back side (lower side) of the main body 110. The fastening insertion groove 132 can be inserted into the fastening rod 143 of the height adjustment portion 140. The leg holes 133 are holes for inserting the plurality of rise-limiting legs 144 formed in the height adjustment portion 140, and can be formed in the bottom surface of the device insertion groove 131.

[0077] The height adjustment portion 140 supports the test meter 300 inserted into the device insertion slot 131. When the cell phone 400 is placed on the cell phone placement area 30, the height adjustment portion 140 can be lowered to the lower side of the main body 110 by the force of the cell phone 400 pressing. If the cell phone 400 is placed without the force of the cell phone 400 pressing, the height adjustment portion 140 can not be lowered.

[0078] In addition, the back of the main body 110 can be formed with a plurality of clamping plates 161 or 162 facing each other. The plurality of clamping plates 161 can be used to clamp the cup 40, and if the lower portion of the cup 40 is clamped, the interval between the facing clamping plates needs to be reduced to match the diameter of the lower portion of the cup, and if the upper portion of the cup 40 is clamped, the interval between the facing clamping plates needs to be increased to match the diameter of the upper portion of the cup.

[0079] Referring to Figure 4 and Figure 5 The height adjustment portion 140 will be described in more detail. Figure 4 is an exploded perspective view of a height adjustment portion in a test meter support according to an embodiment of the present application. Figure 5 is a perspective view showing the installation of a height adjustment portion on a test meter support according to an embodiment of the present application.

[0080] The height adjustment portion 140 can include a support plate 141, a fixing plate 142, a fastening rod 143, a plurality of rising restriction legs 144, and an elastic body 145.

[0081] The support plate 141 is made in a plate shape and is located above the bottom surface of the device insertion slot 131. The support plate 141 is located at a position spaced apart from the bottom surface in an initial position where the test meter 300 is not inserted, and when the test meter 300 is pressed by the cell phone 400, the support plate 141 is lowered to the bottom surface and closely contacts the bottom surface. Thereafter, when the cell phone 400 is removed from the support 100, the support plate 141 is restored to the initial position by the elastic body 145.

[0082] When the test meter 300 is placed on the device placement portion 130, the test meter 300 is located at the upper portion. The support plate 141 as a whole can be circular, but can be made in various shapes that can be inserted into the device insertion slot 131.

[0083] The fixing plate 142 is formed to protrude in a vertical direction at the edge of the support plate 141 and fixes the test meter 300 by abutting against the side surface of the test meter 300 located above the support plate 141. In addition, if it is made to fix the test meter 300 inserted into the device insertion slot 131, the fixing plate 142 can be omitted.

[0084] The fastening bar 143 protrudes from the lower surface (back surface) of the support plate 141 to the lower side, and has a shape corresponding to that of the fastening insertion groove 132 to be inserted into the fastening insertion groove 132. For example, the fastening bar 143 can have a bar shape or a cylindrical shape, etc.

[0085] The plurality of ascent restriction legs 144 protrude from the lower surface of the support plate 141 to the lower side, and pass through the leg hole 133 of the device placement portion 130. The distal end of the ascent restriction leg 144 is formed with a stopper 144a which is caught in the leg hole 133 when the support plate 141 ascends due to the elastic body 145, and prevents the support plate 141 from further ascending.

[0086] The elastic body 145 is inserted into the fastening insertion groove 132 in a state of being sleeved on the fastening bar 143, and contracts and has an elastic force when the force of the cell phone 400 pressing is applied, and the support plate 141 and the tester 300 are made to ascend by the elastic force when the force of the cell phone 400 pressing is removed. The elastic body 145 can be a spring, and can be made in various forms other than a spring.
