Description

Technical Field

[0001] This application relates to the field of temperature and humidity monitoring equipment, and more particularly to a temperature and humidity recording transmitter. Background Technology

[0002] A temperature and humidity transmitter is a device that measures temperature and humidity. It typically includes an integrated temperature and humidity probe to acquire temperature and humidity signals and is widely used in various fields that require the measurement and control of temperature and humidity in the air.

[0003] The temperature and humidity transmitter in this application is mainly used in cold chain transportation. The temperature and humidity probe cable can be up to 30 meters long, so that the temperature and humidity probe can be installed inside the transport container to collect the temperature and humidity signals inside the transport container. The data display box is installed in the driver's cab and connected to the temperature and humidity probe so that the driver can clearly understand the environment inside the transport container.

[0004] Conventional data display boxes are typically fixed using expansion screws and hoist holes. The data display box's wiring port, charging port, and data cable interface are located at the bottom. After the wiring is installed, the data display box can only lie on the dashboard, making it inconvenient for the driver to observe the data displayed on the data display box.

[0005] If a rotating bracket is installed behind the data display box, the bracket will unfold and form an "A" shape with the data display box body during use. At this time, the bottom of the data display box will still be in contact with the dashboard, and the connection of the data cable will affect the placement of the data display box.

[0006] Therefore, how to design a temperature and humidity recording transmitter that is easy to install in the driver's cab has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] This application provides a temperature and humidity recording transmitter to at least solve the above-mentioned technical problems existing in the prior art.

[0008] A temperature and humidity recording transmitter is provided, including a data display box, a bracket rotatably mounted on the back of the data display box, and a locking mechanism;

[0009] The locking mechanism is installed on the data display box or bracket to switch the bracket between a first state and a second state; in the first state, the bracket is attached to the back of the data display box, and in the second state, the bracket is flipped to leave space between the bottom of the data display box and the dashboard for data cable insertion.

[0010] Positioning plate and angle adjustment mechanism: The positioning plate is connected to the bracket through the angle adjustment mechanism to adjust the angle of the data display box;

[0011] The positioning mechanism is installed on the positioning plate to fix the positioning plate to the dashboard.

[0012] In one embodiment, the locking mechanism includes a locking tongue, a first locking hole, and a second locking hole. The locking tongue is slidably mounted on the bracket. Both the first locking hole and the second locking hole are located on the data display box. In a first state, the locking tongue is inserted into the first locking hole, and in a second state, the locking tongue is inserted into the second locking hole.

[0014] In one embodiment, an auxiliary groove is also included, which is disposed on the bracket and communicates with the sliding groove, and a push handle extending out of the bracket through the auxiliary groove is fixed on the locking tongue.

[0015] In one embodiment, a compression spring is also included, with one end of the compression spring abutting against the inner wall of the sliding groove and the other end of the compression spring abutting against the locking tongue.

[0016] In one embodiment, the angle adjustment mechanism includes a limiting hole and an adjusting rod. The limiting hole is disposed on the side wall of the positioning plate, and the adjusting rod is mounted on the bracket and slidably connected along the axial direction of the limiting hole. The mechanism also includes a limiting member that restricts the relative rotation of the adjusting rod and the bracket. The positioning plate and the bracket are rotatably connected by a rotating shaft. When the adjusting rod is inserted into the limiting hole, the positioning plate and the bracket are locked.

[0017] In one embodiment, the positioning plate is U-shaped, and the bracket is provided with a mounting groove. The positioning plate is rotatably installed in the mounting groove. The bracket is also provided with an unlocking groove. A through hole is provided between the unlocking groove and the mounting groove. The adjusting rod is slidably installed in the unlocking groove and extends to the mounting groove through the through hole.

[0018] In one embodiment, the adjusting rod includes an adjusting part and a pushing part. The cross-section of the adjusting part is rectangular, the cross-section of the through hole is consistent with the cross-section of the adjusting part, and the peripheral wall of the limiting hole is provided with a plurality of insertion slots for the side edge of the adjusting part to be inserted.

[0019] In one embodiment, an unlocking groove extends from the end of the pushing portion.

[0020] In one embodiment, the positioning mechanism includes an adhesive tape, which is fixedly mounted on the positioning plate.

[0021] Compared with the prior art, the temperature and humidity recording transmitter of this application has the following advantages:

[0022] This application flips the bracket to a second state to leave space between the bottom of the data display box and the dashboard, which facilitates the installation of the data cable and solves the problem of the data cable affecting the installation of the data display box.

[0023] The angle between the positioning plate and the bracket is adjusted by using an angle adjustment mechanism. Then, the positioning plate is fixed to the dashboard by the positioning mechanism. This allows the tilt angle of the data display box to be adjusted while it is being installed, making it easier for the driver to observe the data on the data display box.

[0042] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] like Figure 1 As shown, the device includes a data display box 1. The bottom of the data display box 1 is provided with an interface for connecting lines such as charging cable, temperature and humidity probe cable, and data cable. The back of the data display box 1 is provided with a bracket 2. Under normal circumstances, the bracket 2 is fastened to the data display box 1 by a snap-fit ​​method, thereby encapsulating the power supply inside the data display box 1.

[0044] It is worth noting that the back of Data Display Box 1 refers to the back side of the display screen of Data Display Box 1.

[0045] In order to allow the data display box 1 to be placed at an angle, the bracket 2 can be installed on the back of the data display box 1 by means of a rotating connection. When the bracket 2 is unfolded, the bracket 2 and the data display box 1 form an "A" shape to support the data display box 1. However, in this case, the gap between the interface of the data display box 1 and the dashboard is small, which is still not conducive to the installation of data cables and will affect the stability of the data display box 1.

[0046] In this embodiment, as Figure 1 As shown, the bracket 2 is rotatably connected to the data display box 1 by a rotating rod. Specifically, the rotating rod is installed near the bottom of the data display box 1. The bracket 2 can rotate around the rotating rod and switch between the first state and the second state.

[0047] It is worth noting here that Figure 1 The first state, Figure 3In the second state, the bracket 2 flips from the first state to the second state, and the flip angle is greater than 90 degrees. In this embodiment, the flip angle of the bracket 2 is 120°. The free end of the bracket 2 is located below the bottom of the data display box 1 so that the bottom of the data display box 1 and the dashboard surface are left with space for the installation of data cables.

[0048] In this context, the free end of bracket 2 refers to the end furthest from the rotating rod.

[0049] In order to ensure that the bracket 2 remains relatively stationary with respect to the data display box 1 in both the first and second states, in this embodiment, as follows: Figure 2 and Figure 4 As shown, it also includes a locking mechanism 3, which is mounted on the bracket 2 or the data display box 1.

[0050] Specifically, in this embodiment, such as Figure 2 and Figure 4 As shown, the locking mechanism 3 includes a locking tongue 31, a first locking hole 32, and a second locking hole 33. The first locking hole 32 and the second locking hole 33 are circumferentially distributed around the axis of the rotating rod on the data display box 1. The locking tongue 31 is slidably mounted on the bracket 2. In the first state, the locking tongue 31 is inserted into the first locking hole 32, at which time the bracket 2 is attached to the back of the data display box 1, sealing the power supply inside the data display box 1. In the second state, as shown... Figure 3 As shown, at this time, the locking tongue 31 is inserted into the second locking hole 33, leaving space between the bottom of the data display box 1 and the dashboard for the installation of the data cable.

[0051] To achieve the installation of the locking tongue 31, in this embodiment, as follows: Figure 2 and Figure 6 As shown, the bracket 2 is provided with a sliding groove 34, the axis of the sliding groove 34 is set perpendicular to the axis of the rotating rod, and the locking tongue 31 is slidably installed in the sliding groove 34. Specifically, the outer wall of the locking tongue 31 is slidably connected to the inner wall of the sliding groove 34.

[0052] To facilitate the sliding of the locking tongue 31 within the sliding groove 34, in this embodiment, as follows: Figure 2 and Figure 6 As shown, the bracket 2 is also provided with an auxiliary groove 35 that communicates with the sliding groove 34, and a push handle 36 that extends out of the bracket 2 through the auxiliary groove 35 is fixed on the locking tongue 31. The locking tongue 31 can be moved in the sliding groove 34 by the push handle 36.

[0053] To improve the stability of the sliding of the locking tongue 31, in this embodiment, as follows: Figure 2 As shown, a guide rod 38 is fixedly installed in the sliding groove 34, and a guide hole is provided on the latch 31 for the guide rod 38 to be inserted. The guide rod 38 is used to control the sliding direction of the latch 31 and improve the stability of the latch 31 sliding.

[0054] To prevent the locking tongue 31 from moving arbitrarily during the flipping of the bracket 2, in this embodiment, as follows: Figure 2 and Figure 6 As shown, it also includes a compression spring 37, which is sleeved on the outside of the guide rod 38. One end of the compression spring 37 abuts against the inner wall of the sliding groove 34, and the other end of the compression spring 37 abuts against the locking tongue 31. The pushing force of the compression spring 37 can maintain the stability of the locking tongue 31 and solve the problem of the locking tongue 31 moving arbitrarily.

[0055] After the bracket 2 switches from the first state to the second state to facilitate the installation of the data cable, in order to fix the data display box 1 on the dashboard, in this embodiment, as follows: Figure 4 and Figure 5 As shown, a positioning plate 4 is provided on the bracket 2, and a positioning mechanism 6 is provided on the positioning plate 4. The positioning mechanism 6 can fix the positioning plate 4 to the dashboard.

[0056] Specifically, such as Figure 6 As shown, the positioning mechanism 6 includes tape, which is fixedly installed on the positioning plate 4. The tape can be double-sided tape, so as to stick the positioning plate 4 to the dashboard.

[0057] In this embodiment, the positioning plate 4 is U-shaped, and it is rotatably connected to the bracket 2 via a pivot. It is worth noting that the pivot is located on the side furthest from the locking mechanism 3.

[0058] After the positioning plate 4 is fixed on the dashboard, in order to adjust the angle of the data display box 1 and facilitate the driver's observation of the data, in this embodiment, as shown in the figure, the positioning plate 4 and the bracket 2 are connected by an angle adjustment mechanism 5, so that the angle between the positioning plate 4 and the bracket 2 can be adjusted, thereby realizing the adjustment of the tilt angle of the data display box 1.

[0059] Specifically, such as Figure 6 As shown, the angle adjustment mechanism 5 includes a limiting hole 51 and an adjusting rod 52. The limiting hole 51 is set on the side wall of the positioning plate 4, and the adjusting rod 52 is slidably mounted on the bracket 2. The axis of the adjusting rod 52 coincides with the axis of the limiting hole 51. When the adjusting rod 52 is inserted into the limiting hole 51, the positioning plate 4 and the bracket 2 are locked, restricting the positioning plate 4 from rotating around the axis.

[0060] The bracket 2 is provided with an installation groove 20, the positioning plate 4 is provided in the installation groove 20, and the bracket 2 is provided with an unlocking groove 21. The adjusting rod 52 is provided in the unlocking groove 21, and the inner wall of the unlocking groove 21 is provided with a through hole 22 that communicates with the installation groove 20. The adjusting rod 52 can extend into the installation groove 20 through the through hole 22.

[0061] Specifically, such as Figure 7 As shown, the adjusting rod 52 includes an adjusting part 521 and a pushing part 522. The adjusting part 521 is inserted into the through hole 22, and the pushing part 522 is fixedly connected to the adjusting part 521 and extends out into the unlocking groove 21. The sliding of the adjusting rod 52 is facilitated by the pushing part 522.

[0062] To prevent the adjusting part 521 from rotating during sliding, in this embodiment, as follows: Figure 7 As shown, the cross-sections of the through hole 22 and the adjustment part 521 are both rectangular, and the outer wall of the adjustment part 521 abuts against the inner wall of the through hole 22.

[0063] Furthermore, such as Figure 8 As shown, the cross-section of the adjustment part 521 is square.

[0064] The inner wall of the limiting hole 51 is provided with several circumferentially evenly distributed insertion slots for the side edge of the adjustment part 521 to be inserted, thereby restricting the rotation of the positioning plate 4 and realizing the adjustment of the angle between the positioning plate 4 and the bracket 2.

[0065] It is worth noting that when adjusting the angle of the positioning plate 4, first slide the adjusting rod 52 to move the adjusting part 521 out of the limiting hole 51, then rotate the positioning plate 4 to the appropriate position, and then insert the adjusting part 521 of the adjusting rod 52 into the limiting hole 51.

[0066] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.
