Description

Technical Field

[0001] The utility model relates to the field of collectors, in particular to a network data collection device. Background Art

[0002] At present, a Chinese utility model with the announcement number CN213342979U discloses a network data acquisition device, which belongs to the field of data acquisition technology, and includes a housing, and mounting blocks are arranged on both the left and right sides of the housing, and a circuit board body is arranged above the opposite surfaces of the two mounting blocks, and a heat sink is overlapped on the lower surface of the circuit board body, and the left and right sides of the lower surface of the heat sink are overlapped with limit blocks, and the lower surface of the limit block is fixedly connected with a movable rod. The network data acquisition device fixes the circuit board body in the housing, and uses two limit blocks to support the heat sink, so that the heat sink can not only dissipate heat for the circuit board body, but also play a role of supporting the circuit board body, and under the action of the first spring, it can reduce the shock of the circuit board body, reduce the damage to the circuit board body caused by the collision, thereby protecting the circuit board body and ensuring the service life of the circuit board body.

[0003] Although the existing data acquisition device has good ventilation and heat dissipation effects, there are still other problems during use, such as the lack of bottom protection function. Since the connector is fixed on the circuit board, and the connector port extends out of the outer shell, the circuit board and the outer shell are bound to be in a rigid fixed state. When the bottom of the device collides during carrying, the force generated by the collision will be directly transmitted to the circuit board and other components. The vibration of the outer shell can easily cause failure of the internal circuit board and components, and the fixing effect of the cable is poor. The external cable is only connected to the device by plugging. Although the cable port will not fall off automatically during static use, it is very easy to loosen and fall off when the cable is pulled by external force, and the practicality is poor. In order to solve the above problems, we propose a network data acquisition device. Utility Model Content

[0004] The utility model aims to provide a network data acquisition device, which solves the problem that the existing data acquisition device does not have a bottom protection function and cannot reinforce the connection cables.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a network data acquisition device, including a casing, a circuit board bolted inside the casing, a heat sink installed at the bottom of the circuit board, heat dissipation grooves on both sides of the casing, a mounting frame symmetrically bolted to the bottom of the casing, a buffer seat slidably sleeved inside the mounting frame, a fixing spring bolted between the top of the buffer seat and the mounting frame through a spring fixing sheet, a U-shaped mounting frame installed on the front of the casing, a mounting groove opened on the front of the U-shaped mounting frame, a pressure plate is arranged inside the mounting groove, arc grooves are opened at the bottom of the pressure plate and the inside of the mounting groove, and the top of the pressure plate is rotatably connected to a threaded rod through a bearing.

[0006] By adopting the above technical solution, the connecting cables can be reinforced to prevent the cables from loosening and falling off due to external pulling, thereby improving the stability between the cables and the device. At the same time, it can have a bottom protection function, reduce the transmission of shock energy on the outer casing to the inside, and extend the service life of internal electrical components, which is highly practical.

[0007] The utility model is further configured as follows: a limiting rod is welded inside the installation frame, a limiting groove is arranged on the top of the buffer seat, and the other end of the limiting rod extends to the inside of the limiting groove.

[0008] By adopting the above technical solution, the buffer seat can be limited by setting the limiting rod and the limiting groove, so as to prevent the buffer seat in the installation frame from tilting when sliding up and down.

[0009] The utility model is further configured as follows: an anti-slip pad is installed at the bottom of the buffer seat.

[0010] By adopting the above technical solution and providing the anti-skid pad, the wear-resistant and anti-skid effect of the bottom of the buffer seat can be improved.

[0011] The utility model is further configured as follows: dustproof nets are bolted to both sides of the housing, and the diameter of the dustproof nets is greater than the inner diameter of the heat dissipation slot.

[0012] By adopting the above technical solution, the dust-proof net can be provided to intercept dust and prevent dust in the air from entering the casing through the heat dissipation slot.

[0013] The utility model is further configured as follows: a guide rod is symmetrically welded on the top of the pressing plate, and the other end of the guide rod penetrates and extends to the top of the U-shaped mounting frame.

[0014] By adopting the above technical solution, the pressure plate can be limited by setting the guide rod to prevent the pressure plate from rotating when moving up and down.

[0015] The utility model is further configured as follows: a turning handle is welded on the other end of the threaded rod, and a thread groove is provided on the top of the U-shaped mounting frame.

[0016] By adopting the above technical solution and setting the turning handle, it is convenient for a person to rotate the threaded rod by hand.

[0017] The utility model is further configured as follows: the threaded rod is made of stainless steel.

[0018] By adopting the above technical solution, the threaded rod has the characteristics of high strength, low density and excellent corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model first passes the connecting cable through the installation groove when in use, and then plugs the head end of the cable into the connecting socket of the circuit board. After the plugging of the head end of the cable is completed, the cable body is placed in the arc groove, and then the handle is held by hand and rotated to move the pressure plate downward. After moving downward, the pressure plate clamps the cable body, which can reinforce the connecting cable, prevent the cable from loosening and falling off due to external force, and improve the stability between the cable and the device.

[0021] 2. The utility model causes the buffer seat at the bottom to collide with the table top when the casing falls. After the collision between the buffer seat and the table top, the buffer seat will move into the installation frame through the cooperation of the limit rod and the limit groove. When the buffer seat moves into the installation frame, it will press on the fixed spring to make the fixed spring enter a contracted state. When the fixed spring contracts, its deformation energy will be converted into elastic potential energy to absorb vibration. It can have the function of bottom protection, reduce the inward transmission of shock energy on the outer casing, extend the service life of internal electrical components, and has high practicality.
