Abstract
Description
Technical Field
[0001] This utility model relates to the field of data acquisition terminal technology, specifically a data acquisition terminal. Background Technology
[0002] With the continuous advancement of technology, wireless handheld scanners have appeared in various fields, using RFID technology for scanning. However, existing wireless scanners lack external protective structures, and due to the absence of wires, they are easily damaged when dropped on hard surfaces such as concrete.
[0003] According to a publicly disclosed data acquisition handheld terminal (announcement number: CN222283645U), in the aforementioned application, one side of the terminal body is slid into the protective shell and fits against the inner end face of the protective shell. Then, a pressing plate moves linearly to clamp and fix the side of the terminal body that is not fitted. The above operation is repeated to fit the protective shell onto the other side of the terminal body and fix it. If the terminal body is dropped on the ground, the buffer plates on both sides in contact with the ground will move inward and compress the first spring. The first spring provides a buffer protection effect. At the same time, the driving block on the buffer plate compresses the inclined block. The inclined block is compressed and slides to one side, compressing the second spring. The second spring also provides a buffer protection effect.
[0004] The lack of effective fixation between the two sets of protective shells means that when the handheld terminal is accidentally dropped, the two sets of protective shells may shift relative to each other or even separate completely due to the lack of fixation, resulting in damage to the terminal itself. Utility Model Content
[0005] The purpose of this invention is to provide a data acquisition terminal to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a data acquisition terminal, comprising two sets of protective shells and a terminal body, wherein the two sides of the terminal body are respectively inserted into the interior of the two sets of protective shells, and a connecting component is provided between the two sets of protective shells. The connecting component includes a fixed frame, and two sets of symmetrically arranged sliders are slidably connected inside the fixed frame. The two sets of sliders are respectively fixedly connected to the ends of the two sets of protective shells, and the two sets of sliders are threadedly connected to each other by a bidirectional threaded rod. The bidirectional threaded rod passes through and is rotatably connected to the end of the fixed frame, and a rotating wheel is fixedly connected to the end of the bidirectional threaded rod.
[0007] Preferably, the protective shell has a buffer assembly inside, which includes a compression plate one, which is slidably connected inside the protective shell and fits against one end of the terminal body. The compression plate one is elastically connected to the inner wall of the protective shell by a buffer spring one. A compression plate two is slidably connected inside the protective shell and fits against the other end of the terminal body. The compression plate two is elastically connected to a sliding plate by a buffer spring two. A lead screw is rotatably connected to the side wall of the sliding plate. The lead screw passes through and is threaded to the end of the protective shell. A handwheel is fixedly connected to the end of the lead screw.
[0008] Preferably, buffer plates are provided on both the upper and lower sides of the two sets of protective shells.
[0009] Preferably, a pad is fixedly connected to the side wall of the fixed frame, and a handle and a strap are fixedly connected to the side wall of the pad.
[0010] Preferably, the protective shell has a guide groove on its side wall, and a guide block is slidably connected inside the guide groove. The guide block is fixedly connected to the side wall of the extrusion plate.
[0011] Preferably, the side wall of the slide plate has a through hole, and a T-shaped rod is slidably connected in the through hole, the end of the T-shaped rod being fixedly connected to the side wall of the extrusion plate.
[0012] Compared with the prior art, the present invention provides a data acquisition terminal with the following advantages:
[0013] 1. This data acquisition terminal achieves flexible adjustment of the protective shell spacing through the connecting components, adapting to terminal bodies of different sizes and improving the versatility of the equipment. The cooperation between the bidirectional threaded rod and the slider can not only accurately adjust the spacing, but also limit the relative displacement of the protective shell when the equipment is impacted or dropped, preventing the terminal body from separating from the protective shell and enhancing the stability and safety of the equipment.
[0014] 2. In this data acquisition terminal, buffer spring one and buffer spring two absorb internal vibration energy through elastic deformation. The bidirectional elastic clamping of compression plate one and compression plate two not only ensures the stable installation of the terminal body, but also effectively dissipates force when an impact occurs, greatly reducing the risk of damage to the terminal body due to collision or vibration, and extending the service life of the equipment.

[0019] like Figures 1-3 As shown, this utility model provides a technical solution: a data acquisition terminal, including two sets of protective shells 1 and a terminal body 2. The two sides of the terminal body 2 are respectively inserted into the interior of the two sets of protective shells 1. The protective shells 1 accommodate the two sides of the terminal body 2 through grooves in their side walls, thus achieving the installation of the terminal body 2. Buffer plates 11 are provided on the upper and lower sides of both sets of protective shells 1. When the device is subjected to external impact, the buffer plates 11 preferentially contact the impact source and absorb some energy through their own deformation, reducing the impact force directly transmitted to the terminal body 2.
[0020] A connecting component 3 is provided between the two sets of protective shells 1. The connecting component 3 includes a fixed frame 31, and two sets of symmetrically arranged sliders 32 are slidably connected inside the fixed frame 31 to restrict the movement trajectory of the sliders 32 and ensure that they slide in a fixed direction. The two sets of sliders 32 are fixedly connected to the ends of the two sets of protective shells 1 respectively. The sliders 32 convert the rotational motion of the bidirectional threaded rod 33 into linear motion, driving the protective shell 1 to move. The two sets of sliders 32 are threadedly connected to each other by the bidirectional threaded rod 33, which passes through and is rotatably connected to the end of the fixed frame 31. A rotating wheel 34 is fixedly connected to the end of the bidirectional threaded rod 33. The bidirectional threaded rod 33 has two sections of threads with opposite directions of rotation, which cooperate with the two sets of sliders 32 respectively. The rotating wheel 34 drives the bidirectional threaded rod 33 to rotate, driving the two sets of sliders 32 to move synchronously towards or away from each other, realizing the precise adjustment of the distance between the two sets of protective shells 1 to adapt to terminal bodies 2 of different sizes, while avoiding relative displacement of the protective shells 1 and separation from the terminal body 2 when dropped.
[0021] A pad 35 is fixedly connected to the side wall of the fixed frame 31, and a handle 36 and a strap 37 are fixedly connected to the side wall of the pad 35. The pad 35 provides an installation surface for the handle 36 and the strap 37. The handle 36 makes it easier for the operator to hold the equipment and improves the ease of use. The strap 37 is put around the wrist to prevent the equipment from falling.
[0022] The protective shell 1 is equipped with a buffer assembly 4, which includes a compression plate 41. The compression plate 41 is slidably connected inside the protective shell 1 and is attached to one end of the terminal body 2. The compression plate 41 is elastically connected to the inner wall of the protective shell 1 through a buffer spring 42. The compression plate 41 is directly attached to one end of the terminal body 2, so that the elastic force of the buffer spring 42 is evenly applied to the terminal body 2 to achieve elastic support. When the equipment is subjected to vibration, the energy is absorbed by the compression and rebound deformation of the buffer spring 42, reducing the impact on the terminal body 2.
[0023] The protective shell 1 has a guide groove 43 on its side wall. A guide block 44 is slidably connected inside the guide groove 43. The guide block 44 is fixedly connected to the side wall of the extrusion plate 41. The guide block 44 slides in the guide groove 43 to ensure that the extrusion plate 41 moves smoothly in a straight line and to ensure the stability of the buffering effect.
[0024] An internal slidable compression plate 45 is connected to the protective shell 1. The compression plate 45 is in contact with the other end of the terminal body 2. The compression plate 45, together with the compression plate 41, achieves bidirectional clamping of the terminal body 2. The compression plate 45 is elastically connected to a sliding plate 47 via a buffer spring 46. The buffer spring 46 provides variable buffering force to adapt to different vibration intensities and protects the terminal body 2 through elastic deformation. The sliding plate 47 serves as the connecting carrier between the buffer spring 46 and the lead screw 49, enabling the position adjustment of the compression plate 45.
[0025] The side wall of the slide plate 47 has a through hole, and a T-shaped rod 48 is slidably connected in the through hole. The end of the T-shaped rod 48 is fixedly connected to the side wall of the second extrusion plate 45. The T-shaped rod 48 ensures the stability of the second extrusion plate 45 when it moves, preventing it from shifting or rotating. A lead screw 49 is rotatably connected to the side wall of the slide plate 47. The lead screw 49 passes through and is threaded to the end of the protective shell 1. A handwheel 410 is fixedly connected to the end of the lead screw 49. By rotating the handwheel 410, the lead screw 49 is rotated, and the slide plate 47 is moved through the threaded transmission, thereby adjusting the position of the second extrusion plate 45 and realizing the adjustment of the preload of the terminal body 2.
[0026] In this invention, during use, the spacing of the protective shells 1 is first adjusted according to the actual size of the terminal body 2. Specifically, the rotating wheel 34 is rotated, causing the bidirectional threaded rod 33 to rotate. Since the two oppositely oriented threads on the bidirectional threaded rod 33 engage with two sets of sliders 32, and the sliders 32 are restricted by the fixed frame 31 to slide only in a straight line, the rotation of the bidirectional threaded rod 33 causes the two sets of sliders 32 to move synchronously towards or away from each other, thereby precisely adjusting the spacing of the two sets of protective shells 1 to match the size of the terminal body 2.
[0027] After the spacing is adjusted, insert both sides of the terminal body 2 into the grooves on the side wall of the protective shell 1. Next, adjust the position of the second extrusion plate 45 by rotating the handwheel 410. The handwheel 410 drives the lead screw 49 to rotate, and the threaded engagement between the lead screw 49 and the end of the protective shell 1 causes the slide plate 47 to slide along the inside of the protective shell 1. The slide plate 47 pushes the second extrusion plate 45 to move through the second buffer spring 46 until the second extrusion plate 45 is in contact with the other end of the terminal body 2. At this time, both the first buffer spring 42 and the second buffer spring 46 are in a pre-compressed state, providing a stable elastic clamping force for the terminal body 2.
[0028] During daily use, operators can either hold the handle 36 to operate the equipment or wear the strap 37 on their wrists to prevent accidental drops. When the equipment is subjected to external impact, the buffer plates 11 on the upper and lower sides of the protective shell 1 first come into contact with the impact source and deform, absorbing some of the impact energy. The compression plate 41 and the compression plate 45 further buffer the vibration under the action of the buffer spring 42 and the buffer spring 46, absorbing and dispersing energy through the compression and rebound of the springs, effectively reducing the impact force on the terminal body 2.
[0029] Throughout the process, the sliding of the guide block 44 within the guide groove 43 ensures the smooth movement of the first extrusion plate 41, while the T-shaped rod 48 ensures the stability of the second extrusion plate 45 during movement, preventing it from shifting or rotating, thus ensuring the reliability of the buffering effect. Furthermore, the bidirectional threaded rod 33 not only enables precise adjustment of the spacing between the protective shells 1, but also prevents relative displacement of the two sets of protective shells 1 when the equipment is dropped, avoiding separation between the terminal body 2 and the protective shell 1.
[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
