Abstract
The utility model relates to a nut sealing structure. A screw and a nut are coaxially and fixedly mounted on a flange plate; a seal plug is mounted at the end part of the screw coaxially in a threaded manner; the nut is embedded and mounted in a circular groove formed in the end part of the seal plug; a seal ring is coaxially mounted between the seal plug and the flange plate. According to the utility model, the structure is simple, the design is scientific and reasonable, the implementation is easy, the sealing property of the matching of the screw and the nut is guaranteed, and the protection level of monitoring products is effectively improved.
Description
Technical field
The utility model belongs to the video security monitoring field, especially a kind of nut seal structure.
Background technique
As the monitoring product used in outdoor environment, barrier propterty seems and is even more important.In order to prevent that rainwater or water vapour from entering monitoring product inside and cause device damage or burn, the especially sealing at screw place, usually be designed to tapped hole blind hole and solve this problem.
But run into special circumstances, due to the restriction of physical dimension, in the situation that must use screw-nut to coordinate, because screw-nut is installed rear thread, there is certain gap in cooperation, so solve the sealing problem of nut, seems particularly important.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of female sealing configuration of simple in structure, good seal performance is provided.
Technical solutions of the utility model are achieved in that
A kind of nut seal structure, screw and nut coaxially is packed on flange plate, it is characterized in that: the end coaxial threaded of described screw is installed a seal plug, and described nut is inlaid in the circular groove that the seal plug end is shaped with, at coaxial installation one seal ring of seal plug and the nut outer rim between flange plate.
And, the stifled end of sealing coaxially be shaped with one with the screw of described screw fit, coaxially be shaped with the circular groove that can hold described nut in the end of screw, be shaped with an elongated slot on the seal plug top of corresponding circular groove.
And described elongated slot is word structure or a cross structure.
And described seal ring is made by rubber or foamed material, its structure is rectangle, circle or oval.
Advantage of the present utility model and good effect are:
1, this nut seal structure is by the screw end coaxial threaded, one seal plug being installed, and the stifled end of sealing is shaped with the circular groove that can hold nut, the use of fitted seal circle simultaneously, thus effectively guaranteed the sealability of nut.
2, the utility model is simple in structure, design science is reasonable, is easy to realize, has guaranteed the sealability that screw coordinates with nut, has effectively improved the security level of monitoring product.
The accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the structure sectional view of the utility model seal ring impaction state.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of nut seal structure, as shown in Figure 1, screw 7 and nut 4 coaxially are packed on flange plate 6, and the end coaxial threaded of described screw is installed a seal plug 1, described nut is inlaid in the circular groove 3 that the seal plug end is shaped with, coaxial installation one seal ring 5 between seal plug and flange plate.
In the present embodiment, described seal plug is round structure, the stifled end of sealing coaxially be shaped with one with the screw of described screw fit, end at screw coaxially is shaped with the circular groove that can hold described nut, the height of the degree of depth of this circular groove and diameter and described nut and equal diameters, be shaped with a straight groove 2 corresponding with a word screwdriver (not shown) at the seal plug top of corresponding circular groove, certainly, also can be the cross recess corresponding with cross screwdriver.
Described seal ring is made by rubber or foamed material, has certain consistency and elasticity, and sealing circle rectangle, also can be circle or ellipse.
In use, seal plug is screwed down the utility model, nut is inlaid in circular groove, and by seal ring extrusion-deformation, as shown in Figure 2, sealing stifled with being used in conjunction with of seal ring, effectively improved the sealability of nut.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (4)
1. a nut seal structure, screw and nut coaxially is packed on flange plate, it is characterized in that: the end coaxial threaded of described screw is installed a seal plug, described nut is inlaid in the circular groove that the seal plug end is shaped with, at coaxial installation one seal ring of seal plug and the nut outer rim between flange plate.
2. nut seal structure according to claim 1, it is characterized in that: the stifled end of sealing coaxially be shaped with one with the screw of described screw fit, end at screw coaxially is shaped with the circular groove that can hold described nut, on the seal plug top of corresponding circular groove, is shaped with an elongated slot.
