Description

Technical Field

[0001] The utility model relates to an accessory device used on a mask bracket. Background Art

[0002] As a protective equipment installed on the helmet, the mask can effectively protect the user's facial safety. The common mask consists of a mask bracket and a transparent mask body. The transparent mask body is installed on the mask bracket. The two ends of the mask bracket are respectively connected to the two sides of the protective helmet, and the mask bracket can be rotated up and down with the connection points on both sides as the axis to realize the function of flipping up and down the mask.

[0003] In order to make better use of the head space and increase the corresponding functions, such as setting up accessories such as shooting devices and lighting equipment, which have different connection joints, a common method is to directly set a corresponding connection seat on the helmet that matches the connection joint of the accessory to be installed. However, this will cause different types of accessories to set up multiple different connection seats, which will cause inconvenience in use and increase the weight of the helmet. In addition, different mounting parts may interfere with the helmet, limiting the function of the accessory. Protective helmets are usually also equipped with masks, and setting the mounting part on the mask bracket is an option. However, since the mask bracket itself is relatively light, the additional connection seat needs to be small in size and light in weight, and the firmness of the connection must be ensured, while also requiring wide applicability. Summary of the invention

[0004] The utility model aims to provide a connecting seat for a mask bracket, which can be firmly connected to existing common accessories, has a small volume, is convenient to set up, and has wide applicability.

[0005] The technical solution of the utility model is: a connecting seat for a mask bracket, used for connecting a connecting joint of an accessory, comprising a mounting portion arranged on the mask bracket, wherein a clamping piece for fixing the accessory connecting joint is provided at the top of the mounting portion, and a groove extending toward the top surface of the mask bracket is provided at the bottom of the mounting portion.

[0006] The mounting part can be set on the mask bracket as a fixed structure. The clamping part arranged on the top can be used to fix the connecting joints of common accessory equipment. It has wide adaptability. The groove arranged at the bottom of the mounting part can be embedded in the mask bracket, thereby improving the firmness of the mounting part on the mask bracket and reducing the weight of the mounting part itself, making it easy to use.

[0007] The mounting portion and the mask bracket are integrally formed. The integrally formed arrangement can simplify the processing steps and further improve the structural strength and stability of the overall installation.

[0008] The mounting portion is L-shaped, wherein the long end is connected to the top surface of the mask bracket, and the short end is movably connected to the side wall of the mask bracket. The shape of the mounting portion can better fit the top surface and side wall of the mask bracket, which is conducive to increasing the firmness of the overall structural connection.

[0009] It also includes a connecting part connected to the mounting part, wherein a slide rail with a trapezoidal vertical cross section is provided on the top of the mounting part, a slider matched with the slide rail is provided on the connecting part, and the clamp is provided on the slider. By setting the connecting part slidably connected to the mounting part, it is convenient to remove the clamp, and the connecting part and the mounting part are connected only when the accessories are needed, which is conducive to reducing the overall weight of the mask bracket. The slide rail with a trapezoidal cross section can prevent the slider from falling off from the top, and the contact surface of the trapezoidal side surface is large, which is easy to disperse the pressure of the accessories.

[0010] The groove is arranged on the inner bottom surface of the slide rail, and at least one protrusion cooperating with the groove is arranged on the lower surface of the slider. When the slider enters the slide rail, the protrusion can enter the groove to fix the slider in the slide rail, thereby increasing the fixing effect of the entire connecting seat.

[0011] The groove is arranged on the inner bottom surface of the slide rail, and an elastic arm is arranged below the slider, one end of the elastic arm is hingedly connected to the slider, and the other end extends along the slide rail, and a convex block matching the groove is arranged below the elastic arm. When the slider enters the slide rail, the convex block below the elastic arm can enter the groove, and under the elastic force of the elastic arm, automatic fixation in the sliding direction is achieved, simplifying the operation of connecting and fixing the slider.

[0012] The slider is provided with a limit screw which passes through the slider and is opposite to the protrusion on the elastic arm. By screwing in the limit screw, the elastic arm is pressed downward, the protrusion and the groove are fixed more firmly, and it is convenient to connect the heavy accessory equipment, and the overall connection strength is high.

[0013] A handle extending upward is provided on the free end of the elastic arm. The elastic arm is pulled upward to make the protrusion escape from the groove, so that the slide block can be removed easily and the operation of removing the attached accessories is simple.

[0014] An L-shaped base is provided below the slide block, and the base is connected to the mounting portion by fixing bolts. The shape of the base matches the mounting portion, the fit is tight, and the overall appearance is good.

[0015] The clamping member is a first connecting piece and a second connecting piece that are arranged on the slider and are parallel to each other. The first connecting piece and the second connecting piece are respectively provided with coaxial through holes. A hollow stepped portion extending outward is also provided on the outer side of the first connecting piece, and an internal thread is provided in the stepped portion. The connecting plugs of existing accessories such as sports cameras and waterproof covers can be inserted between the first connecting piece and the second connecting piece, which has strong adaptability. By inserting the fixing bolts used to connect these accessories into the coaxial through holes, the accessories can be directly installed on the connecting portion, thereby achieving the effect of attaching accessories to the mask bracket. In addition, the stepped portion extending outward of the first connecting piece itself can be filled between the connecting plugs of the accessories, better fit the accessory connection joint, provide sufficient friction, and further increase the connection firmness with the accessories. The internal thread in the stepped portion can directly engage with the fixing bolts of the accessory connection, thereby achieving a self-fixing effect.

[0016] The clamping member is a standardized accessory mounting rail, a flashlight clip or an LED light holder arranged on the slider. The standardized accessory mounting rail, the flashlight clip and the LED light holder are all common existing accessory connection joints, which are easy to obtain, and can realize universal connection of common accessories by directly setting them on the connection part, which has wide adaptability and further increases the use function of the mask bracket.

[0017] The utility model has the advantages that a connection seat for connecting external accessories can be effectively and quickly arranged on the mask bracket, so that existing common accessories can be conveniently connected, the operation is simple, the connection is firm and stable, and the applicability is wide.
