Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a static load tester. Background Technology
[0002] Static load testing is a field test in engineering geology that involves determining the deformation modulus of soil under natural conditions, the continuity of soil deformation over time, and estimating the bearing capacity of the foundation under load conditions close to actual foundation conditions, using a certain vertical pressure. A static load testing instrument is involved in static load testing.
[0003] Currently used static load testing instruments include the instrument body and accessories such as displacement sensors, pressure sensors, and connecting cables. The instrument body includes a housing containing internal electronic components and a display screen mounted on the housing for displaying data. During testing, the sensor is connected to the instrument via the connecting cable, placed at the test position, and the readings are displayed on the screen. The data can also be imported into a computer for analysis using software.
[0004] In actual working conditions, due to the poor environment of the construction site, the wind often blows up dust, and the tester itself is often covered with dust. The dust on the display screen makes it difficult for the staff to observe the readings. On the construction site, the dust can only be wiped clean by hand, which is inconvenient and will cause wear and tear on the display screen. After repeated use, the touch screen will become unusable, affecting the normal use of the tester. Utility Model Content
[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a static load tester that can protect the display screen, is easy to replace, and is convenient to use.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A static load tester includes a tester body, the tester body including a shell, a display screen mounted on the front side of the shell, a boss provided on the outer periphery of the shell facing the display screen, a frame placed on the boss, a protective film fixed inside the frame, the protective film facing the display screen; the boss has an outward inclined surface, a pressure frame is installed on the shell through a connecting structure, the pressure frame has a pressure area that conforms to the frame, and the pressure frame has an inner inclined surface that fits against the outer inclined surface.
[0008] In this way, the frame is placed on the raised platform, with the protective film facing the display screen to protect it. A pressure frame presses down on the frame, ensuring its stable installation on the housing. The pressure frame is connected to the housing via a connecting structure; when replacement is needed, simply remove the pressure frame to remove the frame. Steps are provided to facilitate frame placement and prevent the frame from protruding beyond the housing's outer edge. The pressure area limits the frame's movement, preventing it from interfering with the display screen's touch functionality. The upper and lower slopes increase the contact area between the pressure frame and the housing, making the installation more stable and providing a positioning effect, resulting in a better fit between the pressure frame and the housing.
[0009] Preferably, the connection structure includes a groove formed on the outer shell, a first magnet is fixed in the groove, and a second magnet is fixed in front of the first magnet in the pressure frame. The first magnet and the second magnet have opposite polarities and the first magnet can attract the second magnet.
[0010] Preferably, limiting frames are symmetrically installed on both sides of the outer shell, with the two limiting frames spaced apart, and the outer surface of the pressure frame is in contact with the inner surface of the limiting frame.
[0011] Preferably, handles are fixedly installed on the outer sides of both ends of the pressure frame, the handles are spaced apart from the outer shell, and the handles are located in the gap between the two limiting frames.
[0012] Preferably, anti-collision blocks are fixed at the four corners and both sides of the shell.
[0013] Preferably, the display screen is a resistive screen, and the protective film is a PE soft film.
[0014] In summary, this static load tester has the advantages of protecting the display screen, being easy to replace, and being convenient to use. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0022] like Figure 1-6 As shown, a static load tester includes a tester body 1, which includes a shell. A display screen 2 is mounted on the front side of the shell. A boss 3 is provided on the outer periphery of the shell facing the display screen. A frame 4 is placed on the boss. A protective film 5 is fixed inside the frame and faces the display screen. An outer inclined surface 6 is provided on the boss. A pressure frame 7 is installed on the shell through a connecting structure. The pressure frame has a pressure area 8 that conforms to the frame. The pressure frame has an inner inclined surface 9 that fits against the outer inclined surface.
[0023] In this way, the frame is placed on the raised platform, with the protective film facing the display screen to protect it. A pressure frame presses down on the frame, ensuring its stable installation on the housing. The pressure frame is connected to the housing via a connecting structure; when replacement is needed, simply remove the pressure frame to remove the frame. Steps are provided to facilitate frame placement and prevent the frame from protruding beyond the housing's outer edge. The pressure area limits the frame's movement, preventing it from interfering with the display screen's touch functionality. The upper and lower slopes increase the contact area between the pressure frame and the housing, making the installation more stable and providing a positioning effect, resulting in a better fit between the pressure frame and the housing.
[0024] The casing contains a circuit board and other electrical components that connect to the display screen, which is an existing structure.
[0025] In implementation, the connection structure includes a groove formed in the outer casing, in which a first magnet 10 is fixed. A second magnet 11 is fixed to the pressure frame opposite to the first magnet. The first and second magnets have opposite polarities, and the first magnet can attract the second magnet. The arrangement of the first and second magnets allows the pressure frame to be quickly connected to or disconnected from the outer casing.
[0026] In implementation, limiting frames 12 are symmetrically installed on both sides of the outer shell, with the two limiting frames spaced apart. The outer surface of the pressure frame is in contact with the inner surface of the limiting frame. The limiting frames provide a limit for the pressure frame, making the installation of the pressure frame more accurate and better securing the frame.
[0027] In implementation, handles 13 are fixedly installed on the outer sides of both ends of the pressure frame. The handles are spaced apart from the outer shell and are located within the gap between the two limiting frames. The handles facilitate the removal of the pressure frame. The spaced-apart design of the handles from the outer shell also facilitates hand gripping.
[0028] During implementation, anti-collision blocks 14 are fixed at the four corners and both sides of the shell to protect the outer shell.
[0029] In practice, the display screen is a resistive touchscreen, and the protective film is a PE soft film. This design facilitates pressing the resistive touchscreen and is convenient to use. When the PE soft film needs to be replaced, the frame is removed, the PE soft film is removed from the frame, and then a new PE soft film is adhered to the frame.
[0030] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
