The position fixation of the sensor and the mounting plate is achieved by matching a limit plate with symmetrical grooves on the surface of the sensor and the pins on both sides of the mounting plate.

[0004] However, when implementing the above technical solution, the following problems exist: the above device requires the cooperation of multiple people when placing the sensor on the surface of the mounting plate, and the latches on both sides slide independently, and under the action of the spring, the initial state is to protrude from the inner wall of the mounting cylinder in the mounting plate. When placing the sensor into the mounting cylinder, it is necessary to pull the latches on both sides to prevent the position of the latches from hindering the placement of the sensor.

[0029] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1-6 As shown, a sensor locking and mounting mechanism includes a sensor body 1 and a mounting plate 2;

[0031] It should be noted that the mounting plate 2 includes a mounting plate 2 having the same shape as that in the reference patent, a mounting cylinder, and a threaded column on the mounting plate 2, which provides space and structure for mounting the sensor body 1 and can be fixed to the surface of other parts;

[0032] A fixing mechanism is provided between the sensor body 1 and the mounting plate 2, and the fixing mechanism includes:

[0033] A fixing sleeve 31, the inner ring of which is engaged with the sensor body 1, and a fixing groove 32 is symmetrically formed on the surface of the fixing sleeve 31;

[0034] A pressing post 33, wherein the pressing post 33 is slidably connected to the interior of the mounting plate 2, and a mounting spring is fixedly connected between the pressing post 33 and the mounting plate 2;

[0035] A plurality of drive blocks 34 are slidably connected to the interior of the mounting plate 2. The plurality of drive blocks 34 are symmetrically arranged. The side of the drive block 34 close to the pressing post 33 is arc-shaped, and the cross-sectional size of the drive block 34 gradually increases in the direction away from the pressing post 33. The drive block 34 is in close contact with the pressing post 33. A connecting spring is fixedly connected between the drive blocks 34;

[0036] The driving block 34 is in contact with the surface of the pressing post 33, and the cross-sectional area of ​​the driving block 34 on the side away from the pressing post 33 is larger than the cross-sectional area of ​​the other side. As a result, the downward sliding of the pressing post 33 increases the distance between the driving blocks 34.

[0037] A plurality of fixing rods 35, each of which is slidably connected to the interior of the mounting plate 2, and each of which is adapted to the fixing slot 32. A connecting rod 36 is slidably connected to one side of the fixing rod 35 and the driving block 34, and a connecting shaft is rotatably connected to the surface of the connecting rod 36, and the connecting shaft is fixedly connected to the interior of the mounting plate 2;

[0038] A connecting rod 36 that rotates at a fixed point is provided between the driving block 34 and the fixing rod 35 so that the moving directions of the driving block 34 and the fixing rod 35 are opposite. When the pressing column 33 moves downward, the distance between the driving block 34 increases, and the fixing rod 35 approaches the sensor body 1 and can be inserted into the fixing groove 32, thereby fixing the position of the mounting plate 2 and the sensor body 1.

[0039] The sensor locking mounting mechanism, in actual application, is provided with a driving block 34 on the side of the pressing column 33 away from the sensor body 1 and a fixed rod 35 that rotates at a fixed point, so that the movement of the pressing column 33 is linked to the movement of the fixing rod 35. The movement distance of the pressing column 33 is controlled by the position of the internal sensor body 1. When the sensor body 1 is placed in the specified position, the fixing rod 35 can be engaged with the fixing groove 32 on the surface of the fixing sleeve 31 to achieve position fixation of the sensor body 1 and the mounting plate 2. Then, in the process of fixing the sensor body 1 to the mounting plate 2, after the positions of the fixing groove 32 and the fixing rod 35 are aligned, the position fixation can be achieved by a single sensor pressing operation. The overall process is simpler and can be completed by one person, which is more practical.

[0040] In some specific embodiments, a sliding groove 41 is formed on the surface of the connecting rod 36, and a sliding shaft 42 is fixedly connected to the side of the fixing rod 35 and the driving block 34 close to the connecting rod 36, and the sliding shaft 42 is adapted to the sliding groove 41;

[0041] In some specific embodiments, the driving block 34 includes an arc-shaped block and a rectangular block, the side of the arc-shaped block close to the pressing post 33 is in contact with the pressing post 33, the sum of the width of the rectangular block and half of the width of the arc-shaped block is greater than the radius of the pressing post 33, and the connecting spring is fixed to the surface of the rectangular block;

[0042] The sum of the width of the rectangular block and half the width of the arc block is set to be larger than the radius of the pressing post 33, thereby preventing the connecting spring from being within the sliding range of the pressing post 33 and avoiding contact between the pressing post 33 and the connecting spring, thereby limiting the expansion and contraction of the connecting spring and affecting subsequent transmission.

[0043] In some specific embodiments, a support rod 51 and a limiting rod 52 are fixedly connected to the mutually symmetrical surfaces of the driving blocks 34, respectively. The width of the support rod 51 is greater than the width of the limiting rod 52, and the limiting rod 52 is slidably connected inside the support rod 51.

[0044] By providing the support rod 51 and the limiting rod 52, the distance between the driving blocks 34 is increased in a separate control mode, thereby facilitating the subsequent removal of the sensor body 1. After the sensor body 1 and the mounting plate 2 are fixed, the positions of the two are further restricted to ensure that the sensor body 1 or the pressing column 33 does not move under the action of gravity, thereby affecting the fixed state.

[0045] In a further embodiment, a movable shaft 53 is fixedly connected to the side of the limiting rod 52 away from the driving block 34, and a limiting gear 54 is slidably connected to the movable shaft 53. A guide tooth 55 and a limiting tooth 56 are fixedly connected to the interior of the support rod 51. The guide tooth 55 and the limiting tooth 56 are both engaged with the limiting gear 54. The guide tooth 55 and the limiting tooth 56 are symmetrically arranged relative to the movable shaft 53.

[0046] In a further embodiment, the width of the guide tooth 55 is greater than or equal to twice the width of the limiting gear 54, the width of the limiting tooth 56 is less than or equal to the width of the limiting gear 54, and the sides of the guide tooth 55 and the limiting tooth 56 away from the driving block 34 are located on the same horizontal plane;

[0047] In some specific embodiments, the fixed rod 35 includes a base rod 61 and an extension rod 62. The extension rod 62 is slidably connected to the inside of the base rod 61. A plurality of operating grooves 63 are formed on the surface of the base rod 61. An operating rod 64 is slidably connected to the inside of the extension rod 62. The operating rod 64 is adapted to the operating groove 63. An extension spring 65 is fixedly connected between the operating rod 64 and the extension rod 62.

[0048] The working principle of the present utility model is as follows: when placing the sensor body 1, first slide the limiting gear 54 so that the surface of the limiting gear 54 is only in contact with the surface of the guide gear 55, and then adjust the length of the fixing rod 35 according to the specific distance between the fixing sleeve 31 and the fixing rod 35;

[0049] When adjusting the length of the fixed rod 35, first press the operating rod 64 to cause one end of the operating rod 64 to slide against the inner wall of the base rod 61, blocking the operating slot 63 along the way during the sliding process. Pull the extension rod 62 to the appropriate position, release the operating slot 63, and the operating rod 64 will return to its original position under the action of the extension spring 65, and the length of the fixed rod 35 will be fixed.

[0050] Then, the sensor body 1 is used to press down the pressing column 33, and the movement of the pressing column 33 causes the distance between the driving blocks 34 to increase, thereby driving the connecting rod 36 at one end to rotate, causing the fixing rod 35 at the other end of the connecting rod 36 to slide toward the fixing groove 32. After the fixing rod 35 is inserted into the fixing groove 32, the sensor body 1 and the mounting plate 2 are initially fixed, and then the limit gear 54 is reset. The guide teeth 55 and the limiting teeth 56 are in contact with the surface of the limit gear 54 at the same time, thereby limiting the distance between the driving blocks 34 and fixing them to the sensor body 1.

[0051] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
