Abstract

The utility model provides safe helmet provided with hidden contractible wind shielding glasses. The safe helmet comprises an outer housing, an inner housing and wind shielding glasses; a movable groove is formed at the front parts of the outer and the inner housings; a linear guide rail hole is formed in the middle of the front part of the inner surface of the outer housing, and chutes are arranged in parallel on the two sides of the linear guide rail hole; a guide block and guide columns respectively in movable connection with the guide rail hole and the chutes are arranged on one face of the wind shielding glasses in the movable groove close to the inner surface of the outer housing; a fixing column is vertically arranged in the middle of the lower surface of a sliding key body arranged at the outer part of the outer housing; two movable elastic tongues arranged at the bottom of the fixing column pass through the guide rail hole and are in stationary fit with the guide block on the wind shielding glasses; a sliding slot for the fixing column to slide is formed between the two parallel edges of the guide rail hole; and a clamping groove arranged on the inner side of the sliding slot is occluded with latches on the two horizontal sides of the fixing column. The safe helmet has the advantages of simple structure and reasonable design, solves the problems of the prior wind shielding glasses of ugly appearance, inconvenient use and easy erosion, and has high market potential and wide market prospect.

Description

Crash helmet with concealed collapsible wind-blocking glass

Technical field

The crash helmet that a kind of outdoor personnel use with concealed collapsible wind-blocking glass.

Background technology

The wind-blocking glass of existing crash helmet generally is fixed in helmet front part sides, and is neither attractive in appearance, and long-time use can make wind-blocking glass produce the downslide displacement, brings inconvenience to the user; The wind-blocking glass of peripheral hardware places the very easily dirty erosion in helmet outside for a long time in addition, may cause potential threat to user's personal safety.

The utility model content

The utility model makes the helmet promptly attractive in appearance by a kind of design with crash helmet of concealed collapsible wind-blocking glass, and it is better that wind-blocking glass is hidden property, can keep the cleaning of wind-blocking glass again for a long time, ensures user's safe handling.

The utility model is made up of shell, inner casing and wind-blocking glass, and the front portion of shell and inner casing forms loose slot, and inner surface of outer cover anteriomedial position is provided with the line slideway hole, the parallel chute that is provided with in both sides; The wind-blocking glass that is built in the loose slot is respectively equipped with guide block and guide pillar and guide rail hole and chute movingly near the one side of inner surface of outer cover; The slide key body lower surface intermediate vertical of being located at housing exterior is provided with fixed leg, and the fixed leg bottom is provided with two activity elasticity tongues, and activity elasticity tongue passes the guide block stationary fit on guide rail hole and the wind-blocking glass; Two parallel edges of guide rail hole form sliding trays that allow fixed leg to slide, and the sliding tray inboard is provided with the latch interlock mutually of draw-in groove and the horizontal both sides of fixed leg.

Using method of the present utility model is: during use, the user applies external force and promotes the draw key body to lower slider, and the draw key body drives wind-blocking glass; The guide block of wind-blocking glass and guide pillar slide in guide rail hole and chute respectively, and the draw key body drives the lower end that wind-blocking glass comes downwards to guide rail hole; When not using, only need apply external force and promote the draw key body and upwards slide and since the guide rail hole upper end stop the chute interlock of the latch of the horizontal both sides of fixed leg and guide rail hole, thereby wind-blocking glass fixed preventing that wind-blocking glass from gliding, and then wind-blocking glass is hidden among the crash helmet.

The utility model is simple in structure, reasonable in design, has solved the shortcoming that wind-blocking glass in the past is not attractive in appearance, use inconvenience and easy dirty erosion, and huge market potential and vast market prospect are arranged.

The specific embodiment

The utility model is described in more detail below in conjunction with accompanying drawing:

Referring to Fig. 1,2,3 and 4, the utility model is made up of shell 1, inner casing 2 and wind-blocking glass 4, and shell 1 forms loose slot 3 with the front portion of inner casing 2, and shell 1 inner surface anteriomedial position is provided with line slideway hole 5, the parallel chute (6,7) that is provided with in both sides; The wind-blocking glass that is built in the loose slot 3 is respectively equipped with guide block 8 and guide pillar (9,10) and guide rail hole 5 and chute (6,7) movingly near the one side of inner surface of outer cover; The slide key body 11 lower surface intermediate vertical of being located at shell 1 outside are provided with fixed leg 12, and fixed leg 12 bottoms are provided with two activity elasticity tongues (13,14), and activity elasticity tongue (13,14) passes guide block 8 stationary fits on guide rail hole 5 and the wind-blocking glass 4; Two parallel edges of guide rail hole 8 form sliding trays 15 that allow fixed leg 12 to slide, and sliding tray 15 inboards are provided with latch 17 interlock mutually of draw-in groove 16 and fixed leg 12 horizontal both sides.

During use, the user applies external force and promotes draw key body 11 to lower slider, and draw key body 11 drives wind-blocking glass 4; The guide block 8 of wind-blocking glass 4 and guide pillar (9,10) slide in guide rail hole 5 and chute (6,7) respectively, and draw key body 11 drives the lower end that wind-blocking glass 4 comes downwards to guide rail hole 5; When not using, only need apply external force and promote upwards slip of draw key body 11, owing to stopping of guide rail hole 5 upper ends, the latch 17 of fixed leg 12 horizontal both sides and draw-in groove 16 interlocks of guide rail hole 5, thereby the fixing wind-blocking glass that prevent of wind-blocking glass 4 are glided, and then wind-blocking glass 4 is hidden among the crash helmet.
