Abstract
The utility model provides a bolt seat which can prevent dust from blocking a hole. The root part of a bolt pipe shrinks inwardly to form a cone shape; a closing plate, a spring and a bottom plate are arranged in the bolt pipe in sequence; the bottom plate is positioned in the intersection of the conical pipe part and the straight pipe part of the bolt pipe; the lower end of the spring is supported on the root part of the bolt pipe through the bottom plate; the closing plate is pressed on the upper end of the spring; a faceplate is arranged on the opening of the bolt pipe and seals the opening thereof; a bolt hole is formed on the middle part of the faceplate and allows the bolt to enter and exit; a protruding part is arranged on the middle part of the closing plate and has the shape and size matched with the bolt hole. When the bolt is pulled out, the closing plate can move to the opening under the action of the spring tension and the protruding part passes through the bolt hole to seal the bolt hole, thereby preventing dirt from entering into the passage.
Description
Technical field
The utility model relates to a kind of plug housing, relates in particular to a kind of tubulose plug housing.
Background technology
The object that door and window etc. often open and close generally uses latch, traditional plug housing is a tubulose, after extracting, latch can expose the mouth of pipe of plug housing, plug housing is stopped up by dust or other foreign material easily, cause latch to insert, or insert not in placely, and in a single day the tubulose plug housing is filled in dirt and just is difficult to its removing.
The utility model content
The technical problems to be solved in the utility model provides a kind of plug housing that can prevent the dust plug-hole.
For addressing the above problem, plug housing of the present utility model comprises the latch pipe, be provided with shrouding, spring and base plate in the latch pipe successively, the lower end of spring by backplanes support at latch pipe root, shrouding is pressed in the spring upper end, the mouth of pipe of latch pipe is provided with the panel with its sealing, and the panel middle part is provided with the pin hole for the latch turnover.
After having adopted above structure, after latch was extracted, shrouding to mouth of pipe motion, was sealed pin hole, thereby is blocked the admission passage of dirt under the effect of spring tension.
As a kind of improvement of the present utility model, the shrouding middle part is provided with shape size and the suitable protuberance of pin hole.The shrouding protuberance passes from the panel pin hole like this, and plane can be realized equal with plane on the panel on it.
As further improvement of the utility model, latch pipe root inwardly is shrunk to taper, and described base plate is positioned at the intersection of Taper Pipe and straight tube.Latch pipe root is tapered can be so that the installation of plug housing and easy to make.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Among the figure: 1 panel, 2 shroudings, 3 latch pipes, 4 springs, 5 base plates.
The specific embodiment
As shown in Figure 1, the latch pipe is cylindric, and its root inwardly shrinks the formation taper, is provided with spring, base plate and shrouding in the latch pipe, base plate places the intersection of Taper Pipe and straight tube, spring places on the base plate, and at latch pipe root, shrouding is pressed in the spring upper end by backplanes support in its lower end, the mouth of pipe of latch pipe is provided with the panel with its sealing, panel is pressed in shrouding in the latch pipe, and the panel middle part is provided with the pin hole for the latch turnover, and the shrouding middle part is provided with shape size and the suitable protuberance of pin hole.After latch was extracted, to mouth of pipe motion, its protuberance passed from the panel pin hole shrouding, thereby blocks the admission passage of dirt under the effect of spring tension.
