Description

Technical Field

[0001] The invention relates to the technical field of intercoms, in particular to a safety helmet-wearable wireless communication intercom dedicated to construction sites. Background Art

[0002] A walkie-talkie is a two-way mobile communication tool. It allows calls without any network support and does not incur any phone charges. It is suitable for relatively fixed and frequent calls and is widely used in shopping malls, hotels, schools, enterprises, construction sites and other places. Most existing walkie-talkies need to be held in the hand all the time when in use, which brings great inconvenience to workers working on the construction site. It is inconvenient for workers to occupy their hands for a long time. Although the walkie-talkie can be placed in the pocket of clothes, it is not firm enough and is easy to fall, causing damage to the walkie-talkie. For this reason, we propose a helmet-wearable wireless communication walkie-talkie specially designed for construction sites. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a helmet-wearable wireless communication intercom specially used for construction sites. By fixing the intercom on the safety helmet, the workers' hands can be effectively freed, making it convenient for the workers to carry out construction work. The intercom is fixed more firmly and is not easy to fall off. It is highly practical and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a safety helmet wearable wireless communication intercom dedicated to construction sites, comprising a helmet body, a movable component and an intercom component;

[0005] Hat body: with brim on the front side;

[0006] Movable assembly: including a pin, a collar, a support, an arc-shaped plate and a side shaft, wherein the pin is symmetrically arranged on the front and rear sides of the cap body, the collar is symmetrically and movably sleeved on the pins on the front and rear sides, the support is arranged on the side of the collar, the two ends of the arc-shaped plate are respectively fixedly connected to the supports on the front and rear sides, and the side shaft is arranged in the middle of the side of the arc-shaped plate;

[0007] Intercom assembly: includes a mounting seat, a guide groove, a rack, a mounting frame and an intercom body, the mounting seat is rotatably connected to the end of the side shaft, the guide groove is opened on the surface of the mounting seat, the rack is slidably connected in the guide groove, the mounting frame is arranged at the bottom end of the rack, the intercom body is arranged in the mounting frame, and the intercom assembly is provided with a fixing assembly, a sliding assembly, a guide assembly and a limit assembly.

[0008] Furthermore, the movable component also includes a nut, which is threadedly connected to a position on the pin located outside the collar. The movable component can achieve reversal of the intercom component by rotating the arc plate, and then the intercom body can be switched left and right as needed. After the reversal is completed, tightening the nut can fix the collar, thereby achieving fixed positioning of the arc plate.

[0009] Furthermore, the intercom assembly also includes a speaker cavity and an antenna. The speaker cavity is arranged on the top of the side of the intercom body, and the antenna is arranged on the top surface of the intercom body.

[0010] Furthermore, the fixing component includes a side groove, a fixing seat, a screw hole, a support plate and a stud. The side groove is opened in the middle of the side of the mounting frame, the fixing seat passes through the side groove and is arranged on the side of the intercom body, the screw hole is opened on the top surface of the fixing seat, the support plate is arranged on the side of the mounting frame, and the stud passes through the surface of the support plate and the position corresponding to the screw hole. After the fixing seat and the side groove are correspondingly matched, the stud and the screw hole are correspondingly matched. The stud can be screwed into the screw hole to fix the fixing seat, thereby fixing the intercom body.

[0011] Furthermore, the sliding assembly includes a middle groove, a limit seat, a guide rod and a first spring. The middle groove is opened on the side of the rack, the limit seat is arranged on the top of the guide groove, the guide rod is arranged on the surface of the limit seat, and the top end of the guide rod passes through the top surface of the middle groove. The first spring is sleeved on the guide rod and is located in the middle groove. When the sliding assembly slides downward, the first spring is compressed, and then after the limit assembly is released, the first spring can be reset, and the rack can be automatically reset at the same time, thereby realizing automatic reset of the intercom body.

[0012] Furthermore, the guide assembly includes a mounting groove, a rotating shaft and a gear, the mounting groove is opened on the side of the guide groove, the rotating shaft passes through the middle of the mounting groove, the gear is fixedly sleeved on the rotating shaft, and the gear is meshed with the rack.

[0013] Furthermore, the limiting assembly includes a bracket, a sliding rod and a wedge block. The bracket is arranged on the side of the mounting seat at a position corresponding to the gear, the sliding rod passes through the side of the bracket, and the wedge block is arranged at the end of the sliding rod, and the wedge block corresponds to the tooth groove on the gear.

[0014] Furthermore, the limiting assembly also includes a second spring, which is sleeved on the slide rod and located in the bracket. When the rack slides downward, the gear rotates counterclockwise. Since the wedge block corresponds to the tooth groove on the gear and the inclined surface faces downward, the slide rod can slide back and forth under the action of the second spring. At the same time, after the wedge block corresponds to the tooth groove on the gear, the gear can be prevented from rotating clockwise, thereby achieving the limitation of the rack.

[0015] Compared with the prior art, the invention has the following beneficial effects: the helmet-wearable wireless communication intercom dedicated to the construction site has the following advantages:

[0016] 1. When the wireless communication intercom specially worn on the helmet for this construction site is needed, the intercom body can be pulled downward to the position corresponding to the mouth. At the same time, the tilt angle of the intercom body can be adjusted by the rotation connection between the side shaft and the mounting base to make the intercom body closer to the mouth.

[0017] 2. The movable component of the helmet-wearable wireless communication intercom dedicated to this construction site can achieve a 180° reversal of the intercom component by rotating the arc plate, and then the intercom body can be switched left and right as needed. After the reversal is completed, tightening the nut can fix the ring, thereby achieving fixed limit of the arc plate.

[0018] 3. The limit assembly of the helmet-wearable wireless communication intercom specially used for this construction site can make the gear rotate counterclockwise when the rack slides downward. Since the wedge block corresponds to the tooth groove on the gear and the inclined surface faces downward, the reciprocating sliding of the slide bar can be achieved under the action of the second spring. At the same time, after the wedge block corresponds to the tooth groove on the gear, the gear can be prevented from rotating clockwise, thereby achieving the limitation of the rack.

[0019] 4. When the rack of the helmet-wearable wireless communication intercom dedicated to this construction site slides downward, the first spring is compressed. After use, the wedge block can be disengaged from the tooth groove of the gear by pulling the slide bar, thereby releasing the limit of the rack. At the same time, the first spring resets the rack automatically, thereby realizing automatic reset of the intercom body. BRIEF DESCRIPTION OF THE DRAWINGS
