Description

Technical Field

[0001] This utility model relates to the technical field of electronic load instruments, and in particular to a support device. Background Technology

[0002] Electronic load testers are mainly used for battery pack capacity testing and maintenance. They simulate a load to control the discharge of DC power supplies (such as batteries below 220V / 3000A). Key functions include various discharge modes such as constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CP), requiring real-time monitoring of parameters such as voltage, current, and temperature.

[0003] Existing electronic load testers use a rotating turntable to rotate a threaded rod, which in turn moves a connecting block within a moving slot. This, in turn, moves the moving seat and support rod to adjust their positions. During the movement of the support rod, the load tester body can be angled. However, the rotational design of the protruding rod and the connecting seat provides rotational freedom, which causes the electronic load tester body to shift due to gravity when tilted, resulting in insufficient support for the electronic load tester. Utility Model Content

[0004] The purpose of this invention is to provide a support device to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A support device includes: a support assembly comprising: symmetrically fixed support columns inside a housing; an electronic load cell body disposed on top of the support columns and rotatably connected to them; an adjustment assembly disposed inside the housing and below the electronic load cell body; and a fixing assembly disposed between the housing and the electronic load cell body, the fixing assembly comprising: support rods symmetrically fixed on both sides of the electronic load cell body; an arc-shaped through-slot penetrating the outer wall of the housing, allowing the support rods and the electronic load cell body to slide together; a slider disposed at one end of the support rods; arc-shaped sliding grooves symmetrically disposed on both sides of the housing; and a positioning rod penetrating the slider, the arc-shaped sliding groove having a positioning groove that engages with the positioning rod, allowing the slider to engage and be fixed to the housing.

[0007] Optionally, a locking block is provided on the outer side of the positioning rod and located inside the slider, and an L-shaped slot that cooperates with the locking block is provided on the inner side wall of the slider.

[0008] Optionally, a spring is fitted on the outer side of the positioning rod and located inside the slider.

[0009] Optionally, the adjustment assembly includes: a support base disposed on the inner bottom side of the placement shell; a threaded rod passing through the support base and rotatably connected to the support base; a movable block sleeved on the outside of the threaded rod and located inside the support base; and a connecting plate disposed between the movable block and the electronic load instrument body and rotatably connected to both the movable block and the electronic load instrument body.

[0010] Optionally, a threaded sleeve is fitted on the outer side of the threaded rod and is located on one side of the support.

[0011] Optionally, a compression plate is provided on one side of the threaded sleeve and is sleeved on the outside of the threaded rod.

[0012] Optionally, an anti-slip pad is provided between the extrusion plate and the support base.

[0013] Optionally, a rubber baffle is provided inside the arc-shaped through groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The support rod slides in the arc-shaped through groove, which in turn drives the slider to slide in the arc-shaped slide groove. When the electronic load instrument body is adjusted to a predetermined angle, the positioning rod is pushed inward, so that the positioning rod is inserted into the corresponding positioning groove, thereby making the support rod and the housing locked together and thus providing auxiliary support for the electronic load instrument body, increasing the support of the electronic load instrument body after the angle is adjusted.

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Given that the rotational design of the protrusion and connecting seat in the current technology provides rotational freedom, the electronic load cell body will shift due to gravity when tilted, resulting in insufficient support for the electronic load cell.

[0028] like Figure 1-5As shown, this utility model embodiment provides a support device, including: a support assembly 1, which includes: a support column 12 symmetrically fixed inside a housing 11; an electronic load cell body 13 disposed on the top of the support column 12 and rotatably connected to the support column 12; an adjustment assembly 14 disposed inside the housing 11 and located below the electronic load cell body 13; and a fixing assembly 2 disposed between the housing 11 and the electronic load cell body 13, which includes: a support rod 21 symmetrically fixed on both sides of the electronic load cell body 13; an arc-shaped through groove 22 penetrating the outer wall of the housing 11, allowing the support rod 21 and the electronic load cell body 13 to be slidably connected; a slider 23 disposed at one end of the support rod 21; an arc-shaped sliding groove 231 symmetrically disposed on both sides of the housing 11; and a positioning rod 24 penetrating the slider 23, with a positioning groove 241 on the arc-shaped sliding groove 231 that matches the positioning rod 24, allowing the slider 23 to be engaged and fixed with the housing 11.

[0029] In use, the lid of the housing 11 is opened, and the electronic load cell body 13 is tilted upward by the adjustment component 14, which adjusts the angle of the electronic load cell body 13 for support. The electronic load cell body 13 can be adjusted to an angle that is easy to view according to the needs of users of different heights. When the electronic load cell body 13 is tilted, the support rod 21 slides in the arc-shaped through groove 22, and the slider 23 slides in the arc-shaped slide groove 231. After the electronic load cell body 13 is adjusted to a predetermined angle, the positioning rod 24 is pushed inward, so that the positioning rod 24 is inserted into the corresponding positioning groove 241, thereby locking and fixing the support rod 21 with the housing 11, thus providing auxiliary support for the electronic load cell body 13 and increasing the support of the electronic load cell body 13 after angle adjustment.

[0030] Specifically, the model of the electronic load instrument body 13 is: N6100.

[0031] Furthermore, a locking block 25 is provided on the outer side of the positioning rod 24 and is located inside the slider 23. An L-shaped slot 251 that matches the locking block 25 is provided on the inner side wall of the slider 23. When the positioning rod 24 is pulled out from the positioning groove 241, the positioning rod 24 is rotated so that the locking block 25 is engaged in the L-shaped slot 251, thereby limiting and fixing the positioning rod 24 and preventing the positioning rod 24 from accidentally entering the positioning groove 241 and from detaching from the slider 23 when the slider 23 slides.

[0032] Furthermore, a spring 26 is sleeved on the outer side of the positioning rod 24 and located inside the slider 23. The elasticity of the spring 26 supports the stability of the positioning rod 24 when it is inserted into the positioning groove 241.

[0033] Furthermore, the adjustment assembly 14 includes: a support base 141 disposed on the inner bottom side of the housing 11; a threaded rod 142 passing through the support base 141 and rotatably connected to the support base 141; a movable block 143 sleeved on the outside of the threaded rod 142 and located inside the support base 141; and a connecting plate 144 disposed between the movable block 143 and the electronic load instrument body 13 and rotatably connected to both the movable block 143 and the electronic load instrument body 13. By rotating the threaded rod 142, the rotating threaded rod 142 pushes the movable block 143 to move within the support base 141, and the connecting plate 144 pushes the electronic load instrument body 13 to deflect and adjust the angle.

[0034] Furthermore, a threaded sleeve 27 is fitted on the outer side of the threaded rod 142 and is located on one side of the support base 141. After the threaded rod 142 is rotated to adjust the angle of the electronic load instrument body 13, the threaded sleeve 27 is rotated. The rotating threaded sleeve 27 moves toward one side of the support base 141 and squeezes, thereby squeezing and locking the threaded rod 142 and increasing the stability of the electronic load instrument body 13 after angle adjustment.

[0035] Furthermore, a compression plate 271 is provided on one side of the threaded sleeve 27 and is sleeved on the outside of the threaded rod 142, which increases the compression area of ​​the threaded sleeve 27 on the side wall of the support seat 141 and improves the stability of the threaded sleeve 27 in compressing and locking the threaded rod 142.

[0036] Furthermore, an anti-slip pad 272 is provided between the extrusion plate 271 and the support base 141, which increases the anti-slip properties of the side wall of the extrusion plate 271 and the support base 141.

[0037] Furthermore, a rubber baffle 28 is provided inside the arc-shaped through groove 22 to block the arc-shaped through groove 22 and prevent dust from entering the interior of the housing 11, while not affecting the sliding of the support rod 21 within the arc-shaped through groove 22.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
