Description
Technical field
It the utility model is related to mechanical fastening techniques field, more particularly to a kind of antenna locking device.
Background technology
In Process of Oil Well Drilling, instrument is by high vibration in well, and the antenna of instrument upper end is easily broken, for this
Kind situation, has special antenna locking disk to lock the antenna of instrument upper end at present.
There are the locking plate of many different structures, such as Publication No. 203395038U on the market, publication date is in January, 2014
The Chinese patent literature of 15 days discloses a kind of locking plate, includes outer shroud, inner ring, bolt, a side end face of described outer shroud
On along its inner ring be circumferentially with annular groove, the outer ring of described inner ring is provided with the shoulder rank to match with annular groove, described
The inner ring face of outer shroud and the outer ring face of inner ring are taper surface, and in the inner ring of described inner ring insertion outer shroud, the shoulder rank of inner ring is put
In in the annular groove of outer shroud, described inner ring, outer shroud are fixed through bolt, and the lateral wall of described outer shroud is provided with suspension ring.Adopt
With above-mentioned technical proposal, the utility model provides a kind of locking plate, and it can facilitate handling, so that its convenient transportation.
Obviously, the locking plate of said structure is not particularly suited for the antenna of the instrument upper end involved by the utility model and locked
Tightly.Meanwhile interference fit is used between the antenna locking disk and aerial head used at present in this area, between being produced after long-time use
Gap, it is impossible to play dual parts of antenna vibration damping and electrical connection.
The content of the invention
The defects of the utility model is intended to present in above-mentioned prior art and deficiency, there is provided a kind of antenna locking disk,
The utility model can be good at locking antenna, and play dual parts of antenna vibration damping and electrical connection.
The utility model is realized by using following technical proposals：
A kind of antenna locking disk, it is characterised in that：Including antenna locking disc main body, lock nut and O-ring seal are described
The overall T-shaped structure of antenna locking disc main body, antenna locking disc main body center is provided with the through hole for accommodating antenna, and in aerial lock
Seal groove is provided with tight disc main body, the O-ring seal is located in seal groove and is located at antenna locking disc main body and antenna
Between, volute spring is provided with the upper end of antenna locking disc main body, lock nut is by screw threads for fastening in antenna locking disk master
At the volute spring of body upper end.
The antenna locking disc main body upper end is provided with the socket of multiple regulation locking plate body openings degree.
The antenna locking disc main body lower end is provided with multiple equally distributed holes.
Compared with prior art, what the utility model was reached has the beneficial effect that：
1st, the utility model antenna locking disc main body upper end is provided with volute spring, realizes that antenna bay holds antenna tightly automatically
Head, it ensure that good electrical connection.
2nd, lock nut is connected at the volute spring of the utility model antenna locking disk upper end, realizes locking plate and aerial head
Dual fixation.
The 3rd, O-ring seal is set inside the utility model antenna locking disk, can prevent drilling fluid from entering locking plate endoporus, subtract
Small locking plate erosion, facilitates the dismounting of locking plate.
4th, the utility model antenna locking disk is uniformly distributed hole, is fixed locking plate and tool joint using special spanner,
Realize that antenna bay is electrically connected with tool joint.
Brief description of the drawings
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail, its
In：
Fig. 1 is structural representation of the present utility model.
Marked in figure：
1st, antenna locking disc main body, 2, be lock nut, 3, O-ring seal, 4, volute spring, 5, socket.
Embodiment
As preferred forms of the present utility model, as shown in Figure of description, the utility model includes antenna locking
Disc main body 1, lock nut 2, O-ring seal 3.
There is seal groove in the endoporus of antenna locking disc main body 1, O-ring seal 3 is loaded to the seal groove of antenna locking disk
In, the big end of antenna locking disk is passed through instrument aerial head down, inserted with spanner in the equal cloth hole of antenna locking disc main body 1, will
Screwed between antenna locking disk and tool joint by screw thread, lock nut 2 is tightened on to the upper end cone of antenna locking disc main body 1
At shape spring 4.
The centre of antenna locking disc main body 1 is provided with socket 5, and both wings have symmetrical handle.By the cushion block of two pieces of same sizes
Tightened with screw.By being equipped with different size cushion block, different openings size, different openings width can be adjusted.To adapt to not
Same specification is tightened object.
The utility model is described in detail above by specific and preferred embodiment, but those skilled in the art should
This understands that the utility model is not limited to embodiment described above, all within the spirit and principles of the utility model, is made
Any modification, equivalent substitution etc., should be included within the scope of protection of the utility model.
