[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] The embodiment of the present application provides an electric wrench with an ambient temperature and humidity sensing system, which can solve the problem of setting the torque of the electric wrench by manual recording and calculation in the related art.

[0033] Reference Figure 1 An electric wrench with an environmental temperature and humidity sensing system comprises an electric wrench body 1, a temperature and humidity sensing device 2 and a data display device. The temperature and humidity sensing device 2 is mounted on the electric wrench body 1 to measure the temperature and humidity of the current environment; the data display device is mounted on the electric wrench body and is electrically connected to the temperature and humidity sensing device and the electric wrench body to display temperature and humidity data and a set torque value.

[0034] In this way, by arranging the temperature and humidity sensing device 2 and the data display device on the electric wrench body 1, the temperature and humidity in the current environment can be measured when the electric wrench is used, and the measured values ​​are sent to the data display device for display. At this time, the operator can obtain the temperature and humidity data and calculate the matching torque value, and then set the electric wrench body 1. Therefore, the electric wrench can be simply and quickly set to a torque that meets the current environmental temperature and humidity, and high-strength bolts can be efficiently tightened subsequently, which significantly improves work efficiency.

[0035] Optionally, in some embodiments, the electric wrench with an ambient temperature and humidity sensing system provided in the embodiments of the present application also includes a data processing device, which is installed on the electric wrench body and is electrically connected to the temperature and humidity sensing device and the electric wrench body for calculating the torque value corresponding to the current ambient temperature and humidity and setting it in the electric wrench body.

[0036] Set it up like this, refer to Figure 2 It can be understood that after sensing the temperature and humidity in the current environment, the temperature and humidity sensing device 2 transmits the data to the data display device and simultaneously transmits the data to the data processing device 3, thereby realizing calculation at the data processing device 3, and directly calculating the torque value corresponding to the current temperature and humidity. At the same time, after the data processing device 3 sets the torque value, it will also transmit the torque value to the data display device, thereby facilitating the operator to grasp the temperature and humidity conditions in the current environment, and automatically set the torque, reducing manual operation, and allowing the operator to timely understand the torque value set in the environment.

[0037] Optionally, the data display device includes a display screen 40 .

[0038] Optionally, the data display device also includes a judgment alarm component (not shown in the figure) for prompting and alarming when the displayed temperature and humidity do not match the torque values.

[0039] Set it up like this, refer to Figure 2 The judgment alarm component can judge the temperature and humidity data transmitted to the data display device and the torque value of the electric wrench, and then when the current torque value does not match the set torque value, a prompt and alarm will be given on the display screen 40, thereby ensuring that the operator can stably tighten the high-strength bolts.

[0040] Optionally, the data processing device 3 is connected to an external cloud for interactive data transmission with the outside.

[0041] Set it up like this, refer to Figure 2, the data of the electric wrench provided in the embodiment of the present application during operation will be uploaded to the external cloud, and then the operator can view it online or input data to the data processing device 3 through the external cloud, so that the use settings of the electric wrench can be adjusted in time when needed.

[0042] Optionally, the electric wrench body 1 comprises an operating body 10 and a gripping portion 11. A screwing head 100 is disposed at one end of the operating body 10; and the gripping portion 11 is disposed at one end of the operating body 10 away from the screwing head 100.

[0043] This arrangement makes it more convenient and labor-saving for the operator to hold the electric wrench to tighten the high-strength bolts. At the same time, since the holding portion 11 is far away from the tightening rotary head 100, the operation is safer and more stable.

[0044] Optionally, the temperature and humidity sensing device 2 and the data processing device 3 are both disposed in the holding portion 11 , and the data display device is disposed at an end of the operating body 10 away from the twisting rotary head 100 .

[0045] In this way, the temperature and humidity sensing device 2 and the data processing device 3 are both arranged outside the operating body 10, avoiding occupying the position of the internal components of the operating body 10 itself, and effectively utilizing the space in the holding portion 11, making the overall structure more compact and reasonable, while avoiding compressing the use space of necessary parts, which is beneficial to the use of the electric wrench.

[0046] Optionally, the holding portion 11 includes the data processing device 3 and the temperature and humidity sensing device 2 which are sequentially arranged in a direction away from the operating body 10 .

[0047] In this way, the temperature and humidity sensing device 2 is arranged at the tail end of the holding part 11, so that the sensing area is further away from the operating body, and the influence of heat emitted by the human hand or the operating body is minimized. The measured ambient temperature and humidity values ​​will be more accurate, thereby improving the accuracy and effectiveness of the electric wrench when in use.

[0048] Optionally, a holding side rod 110 is provided on the side of the holding portion 11 away from the screwing rotary head 100, one end of the holding side rod 110 is connected to the end of the holding portion 11 away from the operating body 10, and the other end is connected to the end of the operating body 10 away from the screwing rotary head 100, and forms a holding area 111 together with the holding portion 11.

[0049] With this arrangement, the gripping area 111 formed by gripping the side rod 110 increases the gripping space, thereby enabling the operator to grip the electric wrench more stably as required, thereby making the operation of the electric wrench more stable.

[0050] Optionally, the holding side rod 110 is provided with anti-slip grooves.

[0051] In this way, the anti-skid pattern increases the friction of the gripping side rod 110 and the entire gripping area 111, further improving the gripping stability of the electric wrench when in use. In this embodiment, preferably, a rubber layer is disposed on the gripping side rod 110 and anti-skid patterns are formed thereon.

[0052] The working principle and beneficial effects of the electric wrench with an environmental temperature and humidity sensing system provided in the embodiment of the present application are as follows: a temperature and humidity sensing device 2 and a data processing device 3 are provided on the electric wrench body 1, so that when the electric wrench is used, the temperature and humidity in the current environment can be measured, and the measured values ​​are sent to the data processing device 3 for processing and calculation, and finally the matched torque value is obtained and the electric wrench body 1 is set. Therefore, the electric wrench can be set to a torque that matches the current environmental temperature and humidity simply and quickly, and high-strength bolts can be tightened efficiently in the subsequent process, significantly improving work efficiency.
