Abstract
A kind of glue injecting head, be threaded connection to seal to solve the rod end of seal bar in existing glue injecting head, sealing effectiveness is unsatisfactory, after sealing, the problem of leaking usually can occur along the screw thread place of seal bar.Comprise glue injecting head, the hole for injecting glue at its upper and lower two ends through is offered in glue injecting head, the sidewall of glue injecting head has the adjustment hole of through glue injecting head, adjustment hole and hole for injecting glue arranged in a crossed manner, adjustment hole is divided into the first adjustment hole and the second adjustment hole by hole for injecting glue, seal bar is inserted with to the direction of the second adjustment hole in adjustment hole by the first adjustment hole, first adjustment hole is with internal thread, the diameter of the second adjustment hole reduces gradually along the inner direction to glue injecting head outside of glue injecting head, seal bar is threaded with the first adjustment hole, and one end sealing contact of seal bar is in the second adjustment hole.The utility model is used for industrial pipeline area of maintenance.
Description
Technical field
The utility model relates to a kind of glue injecting head, is specifically related to a kind of glue injecting head of better tightness.
Background technology
Glue injecting head often need be used as injecting glue instrument in the maintenance of existing industrial pipeline; the injecting glue pipeline of glue injecting head controls the closedown of injecting glue pipeline and open-minded by the seal bar arranged in a crossed manner with it; but because in existing glue injecting head, the rod end of seal bar is threaded connection to seal; sealing effectiveness is unsatisfactory; after sealing, usually can leak along the screw thread place of seal bar.
Summary of the invention
The purpose of this utility model is: provide a kind of glue injecting head, and be threaded connection to seal to solve the rod end of seal bar in existing glue injecting head, sealing effectiveness is unsatisfactory, after sealing, the problem of leaking usually can occur along the screw thread place of seal bar.
Scheme of the present utility model is as follows: a kind of glue injecting head, comprise glue injecting head, the hole for injecting glue at its upper and lower two ends through is offered in glue injecting head, the sidewall of glue injecting head has the adjustment hole of through glue injecting head, adjustment hole and hole for injecting glue arranged in a crossed manner, adjustment hole is divided into the first adjustment hole and the second adjustment hole by hole for injecting glue, seal bar is inserted with to the direction of the second adjustment hole in adjustment hole by the first adjustment hole, first adjustment hole is with internal thread, the diameter of the second adjustment hole reduces gradually along the inner direction to glue injecting head outside of glue injecting head, seal bar is threaded with the first adjustment hole, and one end sealing contact of seal bar is in the second adjustment hole.
Adjustment hole and hole for injecting glue forward arranged in a crossed manner, and the diameter of infall adjustment hole is greater than the diameter of hole for injecting glue.
The other end of seal bar stretches the outside at glue injecting head, and the termination of stretching the seal bar outside glue injecting head offers screwdriver cutter groove.
The one end of stretching the seal bar outside glue injecting head is provided with nut, between the nut in seal bar and glue injecting head, is provided with seal washer.
The injecting glue end of described glue injecting head is provided with external screw thread.
The utility model compared with prior art, although the injecting glue pipeline that major advantage is glue injecting head is control the closedown of injecting glue pipeline and open-minded by the seal bar arranged in a crossed manner with it equally, but the rod end of seal bar is held out against by the rod end of seal bar to seal on the inwall of the second adjustment hole in glue injecting head, eliminate the gap that screw thread brings, sealing effectiveness is better, avoids the generation of leakage;
Be provided with seal washer between nut in seal bar and glue injecting head, also improve the sealing effectiveness between the screw cap end of seal bar and the first adjustment hole, further avoid the generation of leakage.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
Composition graphs 1 and Fig. 2, the utility model embodiment provides a kind of glue injecting head, comprising:
Glue injecting head 1, the hole for injecting glue 2 at its upper and lower two ends through is offered in glue injecting head 1, the sidewall of glue injecting head 1 has the adjustment hole 3 of through glue injecting head 1, adjustment hole 3 is arranged in a crossed manner with hole for injecting glue 2, adjustment hole 3 is divided into the first adjustment hole 31 and the second adjustment hole 32 by hole for injecting glue 2, seal bar 4 is inserted with by the first adjustment hole 31 to the direction of the second adjustment hole 32 in adjustment hole 3, first adjustment hole 31 is with internal thread, the direction of diameter along glue injecting head 1 inside to glue injecting head 1 outside of the second adjustment hole 32 reduces gradually, seal bar 4 is threaded with the first adjustment hole 31, and one end sealing contact of seal bar 4 is in the second adjustment hole 32.
Adjustment hole 3 is arranged in a crossed manner with hole for injecting glue 2 forward, and the diameter of infall adjustment hole 3 is greater than the diameter of hole for injecting glue 2.
The other end of seal bar 4 is stretched in the outside of glue injecting head 1, and the termination of stretching the seal bar 4 outside glue injecting head 1 offers screwdriver cutter groove 41.
The one end of stretching the seal bar 4 outside glue injecting head 1 is provided with nut 42, between the nut 42 in seal bar 4 and glue injecting head 1, is provided with seal washer 5.
The injecting glue end of described glue injecting head 1 is provided with external screw thread.
