[0024] Referring to Figures 1-5 The utility model aims at providing a kind of antenna pedestal pitch face fast insertion limiting mechanism, including shell body 1, shell body 1 top fixedly connected with top cover 2, top cover 2 is equipped with the through hole that passes through up and down, the inside of through hole is slidably connected with clamp head 5.The top of clamp head 5 is equipped with inclined surface portion 52.

[0025] Shell body 1 is equipped with the accommodating cavity that passes through up and down, cavity is equipped with telescopic rod 3, and telescopic rod 3 is fixedly connected with clamping portion 31, and spring 6 is installed between clamping portion 31 and the inner bottom surface of accommodating cavity.Top cover 2 is fixedly connected with the limiting portion 22 matched with clamping portion 31.

[0027] That is, the outer ring side of the top contact part 33 is fixedly connected with the first clamping block 321 and the second clamping block 322, when the first clamping block 321 and the second clamping block 322 are respectively disengaged from the first clamping groove 221 and the second clamping groove 222, the top contact part 33 is away from the inside of the through hole of the top cover 2. But due to the limiting of the top contact part 33, the clamping head 5 is always clamped with the limiting part 22 and cannot continue to be pulled out.

[0028] Therefore, the device can be applied to the rotary opening and closing door. When the spring 6 is in the relaxed state, at this time the first clamping block 321 is clamped in the inside of the first clamping groove 221, the device is in the locked state. In this case, when the first clamping block 321 is rotated to correspond to the second clamping groove 222 by pulling the telescopic rod 3, the spring 6 stores elastic potential energy and pushes the first clamping block 321 to be clamped with the second clamping groove 222 under the influence of elasticity. When the clamping is to be released, only need to pull down the telescopic rod 3 again and rotate the first clamping block 321 to the first clamping groove 221 to complete the locking again. In another state, the top of the clamping head 5 is provided with a slope part 52, when the clamping head 5 is in the extended state, the rotary opening and closing door is closed, the slope part 52 of the clamping head 5 can collide with the door frame of the rotary opening and closing door to produce downward sliding, so that the clamping head 5 is retracted, and when the rotary opening and closing door is completely closed, the clamping head 5 corresponds to the hole in the door frame of the rotary opening and closing door, and the clamping head 5 is extended again under the driving of the spring to complete the locking.

[0029] Preferably, the top surface of the top cover 2 is uniformly provided with a plurality of mounting screw holes 21, and the top of the outer shell 1 is provided with a plurality of bolt holes corresponding to the mounting screw holes 21, and the top cover 2 can be mounted on the outer shell 1 through the cooperation of the mounting screw holes 21 and the bolt holes; that is, the top cover 2 can be detachably connected with the outer shell 1 through bolts.

[0030] Preferably, the inner side of the through hole of the limiting part 22 is provided with a sliding groove 223. Specifically, the sliding groove 223 is oppositely arranged on the inner side of the through hole; and the side surface of the clamping head 5 is fixedly connected with two oppositely arranged sliding blocks 51, and the sliding blocks 51 are matched with the sliding grooves 223.

[0031] Preferably, the side surface of the outer shell 1 is fixedly connected with a base 7, and the base 7 is provided with screw holes for mounting bolts. The device can be installed on the rotary opening and closing door through the base 7; at the same time, after the installation of the clamping head 5, the slope part 52 on the clamping head 5 faces the base 7. Therefore, after the device is installed on the rotary opening and closing door, when the rotary opening and closing door is closed, the slope part 52 of the clamping head 5 can collide with the door frame of the rotary opening and closing door to produce downward sliding, so that the clamping head 5 is retracted, and when the rotary opening and closing door is completely closed, the clamping head 5 corresponds to the hole in the door frame of the rotary opening and closing door, and the clamping head 5 is extended again under the driving of the spring to complete the locking.

The outer ring side of the operating knob 4 is provided with anti-skid teeth for easy holding. The user can operate the telescopic rod 3 through the operating knob 4, which is more convenient.

[0033] Preferably, the spring 6 is fixedly connected with the clamping portion 31 at one end and with the inner bottom surface of the accommodating cavity inside the outer housing 1 at the other end. Specifically, when the spring 6 is relaxed and no rotational potential energy exists, the first clamping block 321 is clamped inside the first clamping groove 221. In this case, when the telescopic rod 3 is pulled and the first clamping block 321 is rotated to correspond to the second clamping groove 222, the spring 6 stores rotational potential energy, and only needs to be pulled down again to release the clamping, or the clamping head 5 is slightly moved downward to cause the first clamping block 321 to disengage from the second clamping groove 222, so that the series of actions of elongation, rotation, re-elongation and locking can be quickly completed under the influence of the elastic potential energy and the rotational potential energy of the spring 6.

[0034] Preferably, the bottom of the clamping portion 31 is provided with an annular spring clamping groove 310. A section of the spring 6 is clamped inside the spring clamping groove 310; at the same time, the inner bottom surface of the accommodating cavity inside the outer housing 1 is provided with a second abutting portion 12, which abuts against one end of the spring 6 away from the spring clamping groove 310.

[0035] Preferably, the accommodating cavity inside the outer housing 1 is provided with a first abutting portion 11 corresponding to the clamping portion 31. The first abutting portion 11 is higher than the second abutting portion 12, and the distance between the first abutting portion 11 and the second abutting portion 12 is greater than the length of the spring 6 after extreme compression.

[0036] In actual use, the operator can control the extension and rotation of the telescopic rod 3 by operating the knob 4, and then control the up-down movement of the clamping part 31 and the clamping and disengagement of the first clamping block 321 and the second clamping block 322 with the corresponding clamping grooves on the limiting part 22, so as to realize the locking and unlocking of the device.

If it is necessary to unlock, the telescopic rod 3 is pulled and rotated, so that the first clamping block 321 corresponds to the second clamping groove 222, and under the action of the elastic potential energy of the spring 6, the first clamping block 321 is quickly clamped with the second clamping groove 222. When relocking, the telescopic rod 3 is only pulled and rotated again, and the first clamping block 321 is rotated back to the first clamping groove 221. In another case, when the rotary swing door is closed, the inclined surface part 52 of the clamping head 5 collides with the door frame, the clamping head 5 is forced to shrink, and after the rotary swing door is completely closed, the clamping head 5 is extended again under the action of the spring 6, and the locking is completed by corresponding to the hole of the door frame. The device is installed on the rotary swing door through the base 7 on the side surface of the outer shell 1, the mounting bolt is fixed on the door through the screw hole on the base 7, and the inclined surface part 52 of the clamping head 5 faces the base 7, so that the clamping head 5 can correctly act on the door frame when the door is closed.

[0037] When the spring 6 is fixedly connected at one end with the clamping part 31 and at the other end with the inner bottom surface of the accommodating cavity in the inner shell 1, when manually unlocking, the first clamping block 321 is rotated to correspond to the second clamping groove 222, and when relocking, only the door closing operation needs to be completed, the clamping head 5 moves slightly downward under the impact of the door frame, the first clamping block 321 is immediately disengaged from the second clamping groove 222, and the clamping head 5 quickly completes a series of actions of elongation, rotation, re-elongation and locking under the influence of the elastic potential energy and the rotation potential energy of the spring 6, and the locking is completed.

[0038] Therefore, the device can realize the quick locking and unlocking of the rotary swing door through the above structure and operation mode, the operation is simple, the locking is stable and reliable, and the device has good practicability and popularization value.
