A sensing part is fixedly arranged on the movable rod, and a photoelectric sensor in communication connection with the sensing part is arranged at the corresponding position of the base and used for detecting position information of the sensing part. Specifically, when an installation head of the detection equipment is in an in-out state, a press-in rod is matched with a to-be-detected emitter in an aligned mode and gets close to the emitter under the action of force, and a movable rod is stressed to move in the opposite direction; the photoelectric sensor feeds back the loading and unloading state of the transmitter mounting head by detecting the position change of the sensing part. After detection is completed, the press-in rod is separated from the emitter, and the movable rod automatically returns to the original position under the action of the elastic piece.

DETAILED DESCRIPTION

[0027] Combine the following Figure 1 and Figure 2 The utility model is described in detail.

[0028] An installation detection device includes a fixing device, a pressing rod 20 and a movable rod 30; wherein the fixing device includes a base 10, on which a first limit block 101 and a second limit block 102 are spaced apart; the pressing rod 20 is arranged on the side of the first limit block 101 away from the second limit block 102; the movable rod 30 passes through the first limit block 101 and the second limit block 102, and an elastic member 304 is arranged between the first limit block 101 and the second limit block 102, and one end of the elastic member 304 abuts against the second limit block 102. The movable rod 30 is provided with a plurality of sensing parts, and the base 10 is provided with a plurality of photoelectric sensors corresponding to the sensing parts. The photoelectric sensor has high sensitivity and fast response speed. By detecting the position change of the sensing part during the movement of the movable rod 30, it can accurately feedback the loading and unloading information of the transmitter installation head, so that the user can adjust the transmitter installation head in time to ensure the stable operation of the equipment. Specifically:

[0029] During the detection, the push rod 20 is first aligned with the transmitter to be detected, and then approaches it under the action of external force. The movable rod 30 is forced to move in the opposite direction. During the movement, the sensing part enters the sensing range and is detected by the photoelectric sensor. When the push rod 20 completely enters the transmitter and the movable rod 30 stops moving, the photoelectric sensor detects the displacement distance of the sensing part and then feeds back the entry or exit signal of the installation head. At this time, the elastic member 304 is in a compressed state. After the detection is completed, the push rod 20 is separated from the transmitter to be detected, and the movable rod 30 automatically returns to the initial state under the elastic force of the elastic member 304.

[0030] In this embodiment, the sensing part includes a first sensing part 301, a second sensing part 302 and a third sensing part 303; specifically, the first sensing part 301 is arranged between the first limit block 101 and the second limit block 102, and the second sensing part 302 and the third sensing part 303 are arranged in sequence at one end of the movable rod 30 away from the first limit block 101; and the distance A1 between the first sensing part 301 and the second sensing part 302 is greater than the distance A2 between the second sensing part 302 and the third sensing part 303.

[0031] In this embodiment, the photoelectric sensor includes a first photoelectric sensor 103, a second photoelectric sensor 104 and a third photoelectric sensor 105, which are respectively used to detect the position information of the first sensing part 301, the second sensing part 302 and the third sensing part 303. Furthermore, the distance B1 between the first photoelectric sensor 103 and the second photoelectric sensor 104 is equal to the distance A1, and the distance B2 between the second photoelectric sensor 104 and the third photoelectric sensor 105 is equal to the distance A2; the distance C1 between the first sensing part 301 and the second limit block 102 is less than the distance C2 of the second sensing part 302 moving to the sensing range of the third photoelectric sensor 105. The coordination of the three groups of sensing parts and photoelectric sensors can realize the loading and unloading detection of the transmitter mounting head with different installation depths. Specifically:

[0032] When detecting the transmitter installation head at the maximum installation depth, the push rod 20 docks with the transmitter to be detected, and the movable rod 30 moves in the opposite direction after receiving the force. During the movement of the movable rod 30, the elastic member 304 is compressed. First, the first sensing part 301 enters the sensing range of the first photoelectric sensor 103. As the movable rod continues to push, the second sensing part 302 enters the sensing range of the second photoelectric sensor 104 until the push rod 20 completely enters the transmitter. The position information of the third sensing part 303 is detected by the third photoelectric sensor 105. After the movable rod 30 stops moving, a feedback signal is sent. At this time, the first sensing part 301 stops approaching the position of the second limit block 102, and because the distance C1 between the first sensing part 301 and the second limit block 102 is smaller than the distance C2 of the second sensing part 302 moving to the sensing range of the third photoelectric sensor 105, the third photoelectric sensor 105 is prevented from sensing the position information of the second sensing part 302.

[0033] In this embodiment, the pressing rod 20 includes a first pressing rod 201 and a second pressing rod 202 to ensure that the pressing rod 20 does not roll accidentally during the detection process, thereby preventing the device from malfunctioning.

[0034] In this embodiment, the installation detection device can be made of aluminum alloy or stainless steel. The appropriate material should be selected according to the specific requirements of the use occasion to ensure good working performance. Specifically, the material selected for the installation detection device in this embodiment is aluminum alloy, which can achieve lightweight and strong corrosion resistance, and can ensure a long service life.

[0035] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
