[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 to Figure 3, is the first embodiment of the utility model, which provides a ground plug mechanism, which can achieve the effect of rapid disassembly and assembly of the fixed object after pre-embedding, and includes a ring 100, a sleeve 101 is provided at the top of the ring 100, and a chamfer 101a is provided at the bottom of the sleeve 101, the bottom of the sleeve 101 is threadedly connected to the bottom of the ring 100, and a tapered hole 101b is provided at the top of the sleeve 101, a plug 103 is sleeved on the tapered hole 101b, and a plug rod 104 is inserted at the top of the plug rod 104, a tapered wall 104a is provided on the bottom peripheral wall of the plug rod 104, and the plug rod 103 is located at the tapered wall 104a and a round pin 105 is inserted along its radial direction, and the two ends of the round pin 105 are respectively clamped with the inner wall of the tapered hole 101b and the tapered wall 104a.

[0030] Specifically, the outer diameter of the sleeve 101 is equal to the outer diameter of the collar 100, and the bottom of the sleeve 101 is coaxially connected with a screw rod 101c, the bottom of the collar 100 is fixedly sleeved with a nut 102, the screw rod 101c is threadedly connected with the screw, the diameter of the tapered hole 101b located in the sleeve 101 is larger than the diameter of the open end of the sleeve 101, and the radius contraction direction of the tapered wall 104a is opposite to that of the tapered hole 101b, and the round pins 105 are distributed in a circular array with respect to the insert 103. Both ends of the round pin 105 are hemispherical, and a spring 106 is arranged between the bottom end of the insertion rod 104 and the insertion tube 103, and a retaining spring 107 is arranged on the bottom inner wall of the insertion tube 103. The bottom end of the spring 106 is in contact with the retaining spring 107, and the spring 106 is pre-loaded. The top edge of the insertion tube 103 is provided with a side strip 103a, and the top of the insertion rod 104 is provided with a flat head 104b. The insertion rod 104, the insertion tube 103, the sleeve 101, and the ring 100 are coaxially arranged.

[0031] The tensioning structure composed of the collar 100, nut 102, sleeve 101 and screw rod 101c of the device has the same principle as that of ordinary expansion screws, except for the direction of expansion. For details, please refer to Example 2. The sleeve 101 of the device replaces the screw part extending from the traditional expansion screw in the form of quick release, so as to facilitate the installation of the box 200 in a limited space where it is inconvenient to operate tools. The method of use is as follows: when pre-embedded tensioning structure, it is necessary to ensure that the sleeve 101 completely enters the hole into which it is inserted, align the fixing hole of the fixed object with the tapered hole 101b of the sleeve 101, and insert the insertion tube with the insertion rod 104. 103 is inserted into the tapered hole 101b through the fixing hole of the fixed object, and the side strip 103a of the insert tube 103 is close to the outer wall of the fixed object. In the process of inserting the insert tube 103, it is necessary to press the insert rod 104 to make the tapered wall 104a move away from the round pin 105 to provide space for the round pin 105 to retract. After the insert tube 103 is inserted into place, the insert rod 104 is released, and the spring 106 pushes the insert rod 104 to make the tapered wall 104a squeeze the round pin 105 outward until the other end of the round pin 105 hits the inner wall of the tapered hole 101b, so that the insert rod 104 and the sleeve 101 are clamped, thereby connecting the fixed object to the device.

[0032] In summary, the device unlocks by pressing the insertion rod 104 and releases the insertion rod 104 to clamp, so that the device can achieve the effect of quickly disassembling and assembling the fixed object after being partially embedded.

[0033] Example 2

[0034] Reference Figure 1 and Figure 6 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a ring 100 of a ground insertion mechanism. By optimizing the expansion of the bottom end of the traditional expansion screw to the top expansion, the edge of the ring 100 is stretched open by the slit 100a and obliquely inserted into the hole wall in the direction of the hole where it is located, thereby providing better anti-slip performance. It includes: the top of the ring 100 is distributed with slits 100a in an annular array, the outer wall of the sleeve 101 is provided with anti-slip lines 100b in an annular array, and the slits 100a and the anti-slip lines 100b are both parallel to the axis of the ring 100.

[0035] The nut 102 of the device is press-fitted with the bottom of the sleeve by interference fit, and the nut 102 is screwed into the bottom screw rod 101c of the sleeve 101, so that the chamfered corner 101a at the bottom of the sleeve 101 is partially squeezed into the top of the ring 100, so that the top of the ring 100 is stretched out in a petal shape through the slit 100a to achieve tension with the hole wall. Since the ring 100 is expanded at the top, the petal-shaped bevel plays a role similar to a barb, which can provide more reliable anti-slip performance.

[0036] The rest of the structure is the same as that of Example 1.

[0037] In summary, the device expands through the top of the ring 100, and the expanded beveled edge is inclined in the opposite direction of the hole, which can play a role similar to a barb and be inserted into the hole wall to provide more reliable anti-slip performance.

[0038] Example 3

[0039] Reference Figures 4 to 6 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a protective cover device to solve the protection problem of the vertical height transmitter installed on the ground, and the protective box 200 cooperates with the ground plug-in mechanism to make the assembly operation simpler, including the ground plug-in mechanism in the above embodiment, which includes a box 200, and the four corners of the bottom of the box 200 are provided with a ground plug-in mechanism, and the ring 100 and the sleeve 101 are pre-buried in the ground at the bottom of the box 200, the insertion tube 103 passes through the inside of the box 200 and is connected to the sleeve 101, a round hole 201 is opened at the top of the box 200, and an observation port 202 is opened on one side of the box 200, and a cabinet door 203 is provided on the side of the box 200 away from the observation port 202.

[0040] The box 200 covers the vertical height transmitter on the ground. The rod of the vertical height transmitter can extend through the circular hole 201 on the top of the box 200. A cabinet door 203 for repairing the vertical height transmitter is set on the side of the box 200. At the same time, an observation port 202 for daily inspection is also opened. After drilling holes in the ground to pre-embed the ring 100 and sleeve 101 of the ground plug mechanism, the cabinet door 203 is opened and the box 200 can be quickly fixed to the ground through the ground plug mechanism insert pipe 103 and insert rod 104 without the aid of other tools. After locking the cabinet door 203, the illegal dismantling of the ground plug mechanism and the box 200 can be prevented, so that the internal structure design of the box 200 is very simple, and there is no need to reserve a wrench operation space for anti-theft dismantling, which can reduce the design and manufacturing costs of the box 200.

[0041] The rest of the structure is the same as that of Example 2.

[0042] In summary, the box 200 can be quickly assembled on the ground, solving the protection problem of the vertical height transmitter installed on the ground, and is safe and reliable.
