Description
Technical field
The utility model is related to nailing device technical field, the noise reduction more particularly, to a kind of nailing device covers and the company of nail casing
Binding structure.
Background technology
Chinese patent discloses a kind of nailing device, the patent No.：201620129833.2 while also disclosing one in further detail
The silencing means of kind nailing device, the patent No.：201620131039.1, by taking a kind of silencing means of nailing device as an example, there are following
It is insufficient：Noise reduction covers and the threaded connection place of nail casing is located at front end, by the rear flange of the rear end face and nail sleeve outer wall of noise reduction set
It abuts and forms sealing, since there are strenuous vibrations during nailing, noise reduction can be caused to cover and follow closely the threaded connection place pine of casing
Dynamic, i.e., noise reduction is covered forms gap between the rear end face that noise reduction can be caused to cover toward anterior displacement and the rear flange for following closely sleeve outer wall, between being somebody's turn to do
Gap can make vessel gas leakage, noise increase, not have erasure effect, need to improve.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of the noise reduction set and nail of nailing device
The connection structure of casing, good seal performance, noise is small when nailing.
To achieve the goals above, the utility model adopts the following technical solution：
A kind of connection structure of the noise reduction set and nail casing of nailing device, including nail casing and noise reduction set, the nail casing
It is set on the outer wall of front there are one the seal groove of annular, the rear end inner wall and the rear portion outer wall of nail casing of the noise reduction set pass through screw thread
Connection, the front inner wall of noise reduction set are with the front outer wall clearance fit of nail casing and close by the sealing ring in seal groove
Envelope forms a silencing cavity between the middle inner wall and the middle outer wall for following closely casing of noise reduction set.
The rear portion outer wall of the nail casing is equipped with the flange extended vertically outward, follows closely before being located at flange on the outer wall of casing
External screw thread is equipped at side, the rear end inner wall of the noise reduction set is equipped with the internal thread to match with external screw thread.
The inner wall front end of the nail casing plugs nail, follows closely the rear on the inner wall of casing positioned at nail and is equipped with and can be covered along nail
The firing pin casing of inside pipe wall movement.
The material of the sealing ring is nitrile rubber.
The utility model has the beneficial effects that：
Even if one, noise reduction is covered toward anterior displacement, the front inner wall of noise reduction set remains unchanged in the sealing stroke range in sealing ring,
Ensure silencing cavity will not gas leakage, noise is small when nailing；
Two, sealing ring can increase resistance, make noise reduction set is whole to be become difficult toward anterior displacement；
Three, the setting of sealing ring reduces cooperation accuracy tolerance so that the front end of the front inner wall and nail casing of noise reduction set
Gap between outer wall can do it is big a bit, this gap is made up by sealing ring, noise when nailing controls completely
In silencing cavity.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：Follow closely casing 1, flange 11, external screw thread 12, seal groove 13, noise reduction set 2, internal thread 21, nail 3, firing pin casing
4, silencing cavity 5, sealing ring 6.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and detailed description：
As shown in Figure 1, the connection structure of the noise reduction set and nail casing of a kind of nailing device, including nail casing 1 and noise reduction set 2,
The inner wall front end of the nail casing 1 plugs nail 3, and being equipped with positioned at the rear of nail 3 on the inner wall of nail casing 1 can be along nail casing 1
The firing pin casing 4 of inner wall movement.The head of nail 3 is equipped with gunpowder, and firing pin casing 4 is internally provided with the firing pin (figure that can fire gunpowder
In be not drawn into), these are the prior art, include the operation principle etc. of nailing device, can refer to existing Patent No.
201620129833.2 nailing device, do not describe in detail herein.
The seal groove 13 of annular there are one being set on the front outer wall of the nail casing 1, the section of the seal groove 13 is semicircle
Shape, the rear end inner wall and the rear portion outer wall of nail casing 1 of the noise reduction set 2 are connected through a screw thread, specially：The nail casing 1
Rear portion outer wall is equipped with the flange 11 extended vertically outward, follows closely and is located on the outer wall of casing 1 at the front of flange 11 equipped with external screw thread
12, the rear end inner wall of the noise reduction set 2 is equipped with the internal thread 21 to match with external screw thread 12.The rear end face of noise reduction set 2 resists flange
11 front end face.
The front inner wall of noise reduction set 2 is with the front outer wall clearance fit for following closely casing 1 and by close in seal groove 13
Seal 6 seals, i.e. sealing ring 6 and the front inner wall of noise reduction set 2 is interference fitted, and the material of the sealing ring 6 is nitrile rubber.Fourth
The wearability of nitrile rubber is higher, and heat resistance is preferable, and bonding force is strong.
A silencing cavity 5 is formed between the middle inner wall and the middle outer wall for following closely casing 1 of noise reduction set 2.
The threaded connection of the nail casing 1 of the utility model and noise reduction set 2 is in rear end, and front end passes through heat safe sealing ring
6 sealings, even if threaded connection place loosens during nailing, i.e., noise reduction set 2 is whole toward anterior displacement, from figure 1 it appears that close
Seal 6 be located at noise reduction set 2 front inner wall centre position, so even noise reduction set 2 displacement, noise reduction set 2 front inner wall according to
In the old sealing stroke range in sealing ring 6.The sealing ring 6 of the utility model can also increase resistance simultaneously, you can make to disappear
Sound set 2 is whole to be become difficult toward anterior displacement.The setting of sealing ring 6 also reduces cooperation accuracy tolerance so that the front end of noise reduction set 2
Gap between inner wall and the front end outer wall for following closely casing 1 can do it is big this gap is a little made up by sealing ring 6,
Noise control completely when nailing is in silencing cavity 5.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
