Abstract
Description
Technical Field
[0001] This application relates to the technical field of VOC detectors, and specifically to a stable VOC detector with a protection function. Background Art
[0002] A VOC detector is an instrument used to detect the concentration of volatile organic compounds. The VOC detector detects the concentration of VOCs in the environment through sensors or detectors, and displays the results on the screen of the instrument or transmits the data to a computer or mobile device.
[0003] Most VOC detectors are handheld terminal devices, which can be easily moved to intuitively detect the concentration of VOCs in different areas. However, due to their portability, the risk of dropping the VOC detector is also increased. Although anti-slip strips are installed outside the VOC detector, there are still situations where it is not grasped firmly, causing the VOC detector to fall. Since there are precise sensor devices on the handheld terminal of the VOC detector, in the case of a fall, the sensor devices located outside the VOC detector will be directly damaged by the collision, resulting in economic losses. For this reason, a stable VOC detector with a protection function is proposed to solve the above-mentioned problems. Utility Model Content
[0004] In view of the deficiencies of the prior art, this application provides a stable VOC detector with a protection function, which has the advantages of effectively protecting the handheld terminal of the VOC detector.
[0005] To achieve the above object, this application provides the following technical solution: A stable VOC detector with a protection function, including a detector body and a protective shell externally disposed outside the detector body, and a connection structure for connecting the protective shell is provided on the detector body;
[0006] The connection structure includes connection columns installed at the upper and lower ends of the detector body and a guide rail frame on the inner wall of the protective shell. The connection columns are slidably connected to the guide rail frame. A spring seat is fixedly installed on the inner wall of the protective shell, and a return spring is fixedly installed between the spring seat and the end of the connection column.
[0007] Further, the protective shell is a shock-proof outer shell, and a fixing groove is recessed on the inner wall of the protective shell, and the fixing groove corresponds to the side shape of the detector body.
[0008] Further, rubber strips are embedded on the inner wall of the fixing groove, and the number of the rubber strips is several.
[0009] Furthermore, connecting bars are fixedly installed at both the upper and lower ends of the detector body, the connecting columns are fixedly connected to the connecting bars, and the lower end of the guide rail frame is open, which can facilitate crossing over the connecting bars.
[0010] Furthermore, a limiting block is fixedly installed at the end of the connecting column. The limiting block is a right-angled triangular block, and the right-angled end of the limiting block faces the middle direction of the connecting column.
[0011] Furthermore, magnetic attraction strips are fixedly installed on the opposite ends of the two protective shells.
[0012] Furthermore, a protrusion is fixedly installed at the top of the connecting column, and the protrusion is arc-shaped.
[0013] Furthermore, a groove is also formed on the outside of the protective shell.
[0014] Furthermore, protective corners are fixedly installed at the four top corners of the protective shell, and inlays are also fixedly installed on the inner walls of the protective corners.
[0015] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0016] For the stable VOC detector with a protective function, by arranging two openable and closable protective shells slidably installed outside the detector body through connecting bars and connecting columns, and installing a return spring and a magnetic attraction strip between the protective shell and the detector body, the closing protection of the two protective shells can be conveniently completed. Additionally, when in the open state, a protrusion is provided to limit the position of the protective shell, which can facilitate the normal use of the detector body. Since the protrusion can be made of a rubber block, when in the open state, being collided will cause the guide rail frame on the protective shell to cross over the protrusion to achieve closing protection, improving the protection performance of the device.

Detailed implementation manners
[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0023] Please refer to Figures 1-4 , a stable VOC detector with a protection function in this embodiment includes a detector body 1 and a protective shell 2 externally disposed outside the detector body 1. The protective shell 2 includes two symmetrically arranged parts on the left and right. By buckling the two parts of the protective shell 2 with each other, the wrapping protection of the detector body 1 can be realized.
[0024] In this embodiment, a connection structure for connecting the protective shell 2 is provided on the detector body 1. The connection structure includes connection columns 5 installed at the upper and lower ends of the detector body 1 and a guide rail frame 6 located on the inner wall of the protective shell 2. The connection column 5 is slidably connected to the guide rail frame 6. Through the relative sliding between the connection column 5 and the guide rail frame 6, the protective shell 2 can slide and open relative to the detector body 1.
[0025] Preferably, the protective shell 2 is made of a shock-proof outer shell. A fixing groove 9 is recessed on the inner wall of the protective shell 2. The fixing groove 9 corresponds to the side shape of the detector body 1, which can improve the contact effect between the protective shell 2 and the detector body 1 in the buckled state.
[0026] It should be noted that a rubber strip 10 is also embedded on the inner wall of the fixing groove 9. The number of the rubber strips 10 is several. The several rubber strips 10 can effectively improve the contact tightness between the detector body 1 and the fixing groove 9.
[0027] In order to reset the protective shell 2, a spring seat 7 is fixedly installed on the inner wall of the protective shell 2 in this embodiment, and a reset spring 8 is fixedly installed between the spring seat 7 and the end of the connection column 5.
[0028] In specific implementation, by pulling the two protective shells 2 to open relative to the detector body 1, the reset spring 8 is stretched, so that the reset spring 8 can pull the two protective shells 2 to buckle relative to each other.
[0029] In this embodiment, connection strips 4 are fixedly installed at both the upper and lower ends of the detector body 1. The connection column 5 is fixedly connected to the connection strip 4. The lower end of the guide rail frame 6 is open, which can facilitate passing over the connection strip 4.
[0030] It should be noted that a limit block 11 is fixedly installed at the end of the connecting column 5. The limit block 11 is a right-angled triangular block, and the right-angled end of the limit block 11 faces the middle direction of the connecting column 5. The limit block 11 can limit the movement range of the protective shell 2 relative to the detector body 1.
[0031] In this embodiment, magnetic attraction strips 13 are fixedly installed on the opposite ends of the two protective shells 2. By the mutual attraction of the two magnetic attraction strips 13, the buckling and closing of the protective shells 2 can be realized.
[0032] In order to temporarily fix the position of the protective shell 2, in this embodiment, a protrusion 12 is fixedly installed at the top of the connecting column 5. The protrusion 12 is arc-shaped and can limit the sliding of the guide rail frame 6 through the protrusion 12.
[0033] In specific implementation, by pushing the guide rail frame 6 over the protrusion 12, the guide rail frame 6 can abut against the other end of the protrusion 12 to realize temporary position limitation.
[0034] In this embodiment, a groove 3 is also formed on the outer part of the protective shell 2. Through the groove 3, it is convenient to pull the two protective shells 2 away from each other relatively.
[0035] It should be noted that protective corners 14 are fixedly installed at the four top corners of the protective shell 2. The protective corners 14 adopt metal outer corners to reduce the deformation of the protective shell 2 caused by collision. An inlay block 15 is also fixedly installed on the inner wall of the protective corner 14. By inserting the inlay block 15 into the protective shell 2 to connect the protective corner 14, the direct force transmitted to the protective shell 2 through the protective corner 14 can be reduced.
[0036] The working principle of the above embodiment is as follows:
[0037] During use, by pulling the two grooves 3 on the protective shell 2 relative to each other, the two protective shells 2 can drive the fixedly connected guide rail frame 6 to slide relative to the connecting column 5 on the detector body 1, so that the two protective shells 2 open relative to the detector body 1. At this time, the detector body 1 can be exposed for use, and at the same time, the outer periphery of the detector body 1 is still protected by the protective shell 2. By continuously pulling the two protective shells 2, the guide rail frame 6 squeezes the protrusion 12 on the connecting column 5 and abuts against the protrusion 12, thereby realizing the position limitation of the protective shell 2 and facilitating the normal use of the detector body 1.
[0038] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.
