Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute limitations on the invention.
The utility model aims at providing a simple structure, convenient operation seal a tight solid screw of gluing and seal with gluing the mouth. The following will describe the sealing nozzle for screw sealing in detail by specific embodiments.
Fig. 1 and fig. 2 show the three-dimensional structure of the sealing nozzle for screw sealing of the present invention, as shown in fig. 1 and fig. 2, a sealing nozzle for screw sealing mainly includes: a screw sealing head 22 sleeved outside the screw head and an injection connecting pipe 21 fixedly connected with the screw sealing head 22. The screw sealing head 22 wraps the outside of the screw head to form a pressurized sealant cavity 23 so as to realize the solidification and shaping of the sealant at the periphery of the screw head. The injection connection tube 21 is a hollow cylinder as a whole and is open in the axial direction. The hollow interior of which forms a passage that communicates with the pressurized sealant chamber 23. More specifically, the glue solution injecting device 1 is communicated with the screw sealing head 22 through the injection connecting pipe 21, and the injection end of the glue solution injecting device 1 extends into the injection connecting pipe 21. Preferably, the screw sealing head 22 and the injection connecting pipe 21 are integrally formed, so that the time for fixedly connecting the two by using other tools is saved.
Compared with the existing mode that the toothpick is stained with glue points around the screw head, the screw sealing head 22 can control the smearing position and the solidification shape of glue; the screw sealing head 22 cooperation can be used through the common equipment that injects the glue solution through pressure in this field, and the injecting glue is more even, seals the process simple operation admittedly, and equipment injects the colloid around the screwhead through injection connecting pipe 21 and screw sealing head 22 and can form fixed shape, promotes pleasing to the eye degree.
In a preferred embodiment of the present invention, as shown in fig. 3 and 4, the glue injection device 1 is a syringe, and the injection end of the syringe extends into the channel. The injector has low cost, small volume and large injection pressure.
In a preferred embodiment of the present invention, the injection connection tube 21 comprises a first connection end 211 and a second connection end 212. The nipple of the injector is arranged in the first connecting end 211, which has guiding function to the injector, and the injector is not easy to shake in the using process. The needle of the syringe is placed in the second connection end 212. The inner diameter of the second connection end 212 is smaller than that of the first connection end 211, so that the channel is divided into two parts with different diameters, and the two parts are respectively correspondingly provided with different parts of the injector, so that the injector is quickly arranged in the injection connection pipe 21. The second connecting end 212 is communicated with the side wall of the screw sealing head 22, and the second connecting end 212 is gradually narrowed as being closer to the screw sealing head 22, so that the colloid propelling speed and the controlled dosage can be ensured.
In a preferred embodiment of the present invention, the injection connection tube 21 is arranged at an acute angle to a plane perpendicular to the axis of the screw head. I.e. the injection connecting tube 21 is arranged obliquely, in accordance with the use habit of people using the syringe-type glue injection apparatus 1. In addition, when the screw head on the workpiece is glued, the shapes of other parts to be installed on the workpiece are also changed, the space where the workpiece is located is different, and particularly when the operation space is narrow or limited by the environment such as the wall surface and the like, the glue can be glued in a mode that the injection connecting pipe 21 is inclined when the gluing is inconvenient through the vertical injection connecting pipe 21; in addition, compared with the vertical glue injection by using the injection connecting pipe 21, the vertical glue injection is not beneficial for the operator to observe the injection condition of the glue injection device 1.
In a preferred embodiment of the present invention, the screw sealing head 22 is cylindrical with an opening at the bottom, the bottom is attached to the workpiece surface of the mounting screw, and the screw sealing head 22 is sleeved outside the screw head to form a pressurized sealant chamber 23 together with the workpiece surface. The cylindrical side wall is provided with a through hole communicating with the passage of the injection connecting tube 21.
In a preferred embodiment of the present invention, the inner diameter of the pressurized sealant chamber 23 near the screw head is larger than the inner diameter of the screw head. Therefore, the glue solution can flow rapidly in the pressurized glue sealing cavity 23, and the forming is accelerated. And is convenient to separate from the pressure glue sealing cavity 23 after the glue is fixed.
The utility model discloses a preferred embodiment, screw seal head 22 is the hollow circular truncated cone form that removes the top, and the glue of beating like this is close to the diameter of the part of workpiece surface more big more, and the colloid of being convenient for is beaten the back, when taking off screw seal head 22, and the colloid of the part of keeping away from workpiece surface is difficult to be interfered by screw seal head 22. The side wall of the truncated cone is provided with a through hole which is communicated with the channel of the injection connecting pipe 21. The inner wall surface of the screw mounting end 221 of the screw sealing head 22 at the end remote from the screw head is in contact with the screw head. The compression sealing end 222 of the screw sealing head 22 adjacent the screw head abuts the surface of the workpiece on which the screw head is mounted. The inner diameter of the compression sealing end 222 is larger than the inner diameter of the screw mounting end 221. The outer surface of the screw head, the inner wall surface of the screw sealing head 22 and the surface of the workpiece jointly form a pressure sealant cavity 23.
The screw sealing head 22 is narrow at the top and wide at the bottom, a pressurizing glue sealing cavity 23 can be reserved for realizing glue solidification and shaping, and meanwhile, the screw mounting end 221 at the upper end of the screw sealing head 22 is connected with the outer wall of the screw head in a sealing mode, so that the glue is prevented from overflowing and the attractiveness is prevented from being influenced. And once the screw mounting end 221 is found to have glue running out, it is an indication that the glue has been run out. The screw sealing head 22 is in a truncated hollow truncated cone shape, so that the side wall of the screw sealing head is more convenient to mount and communicate with the injection connecting pipe 21. The further injection connecting pipe 21 is placed obliquely, and the glue in the injection connecting pipe can quickly flow into the screw sealing head 22.
When the device is used, taking an injector as the glue injection equipment 1 as an example, after a screw head is fixed on a workpiece, the device is installed at the screw head, the screw sealing head 22 is sleeved on the screw head until the pressing sealing end 222 presses the surface of the workpiece, and the screw installation end 221 is fixed at the screw head in a sealing manner, then the nipple end of the injector is installed on the first connection end 211 of the injection connection pipe 21, glue is filled in the glue injection equipment 1, then the piston is pushed to gradually push the glue into the screw sealing head 22 from the injection connection pipe 21, the glue is remained in the pressure glue sealing cavity 23 until solidification and shaping, and finally, glue injection and fixation of the screw head are finished.
