Technical Field

The utility model relates to the technical field of safe theft prevention of bags and suitcases.

Background

Draw-bar boxes, as a common luggage case, are a main category of cases, and security and theft prevention thereof are important problems. The applicant's utility model patent "safety bag" (patent number ZL201821721671.7), a theft-proof scheme of laying detection lines from the opening of the box and the box surface is given, and some existing related technologies are listed, but do not relate to the alarm implementation. Although the mobile communication terminal (such as a mobile phone) can be used for controlling and alarming, the basic form of alarming is that the draw-bar box emits alarming sound and light. The alarm must be arranged in the box body, and the alarm sound and light must also be transmitted out. "a draw-bar box with two alarm system" (utility model patent number ZL201520014089.7), mainly set up the warning on the handle. Other draw-bar boxes have alarms mounted on the inside of the surface of the box, and have covers of specific colors on the outside, and the covers vary depending on the style and color of the box. Therefore, a simple and practical alarm mounting structure which is universal for draw-bar boxes with various styles and colors and does not need to change the appearance of the draw-bar box is lacking.

Disclosure of Invention

The alarm device starts from the structure of the pull rod, and is matched with the alarm support and the alarm device with proper structures, so that the problem of a universal mounting structure for alarming of the pull rod box is solved.

The utility model firstly provides an alarm pull rod as a pull rod box accessory, which comprises a base, a sleeve, a pull rod, a panel and a handle, and is characterized in that a transverse surface or a vertical surface of the panel is provided with a through sound outlet, the inner side of the panel where the sound outlet is positioned is used as a supporting base surface, an alarm support with a basically vertical integral outline and containing the sound outlet is configured, a sound cavity is arranged in the alarm support and reaches the sound outlet, and the configuration structure adopts one of the following three forms:

a) the alarm bracket and the supporting base surface are integrally molded, namely the alarm bracket and the panel are connected into a whole on the material;

b) the supporting base surface is provided with a hook/groove capable of positioning and clamping an attachment component, the alarm bracket is used as an assembly member capable of being assembled and disassembled, and the bottom of the alarm bracket is provided with a hole/strip complementary with the hook/groove, so that the alarm bracket can be hung on the supporting base surface in a matching way and is fixed on the supporting base surface without being pulled off easily;

c) the alarm support is used as a mountable and dismountable matching set and comprises a light and thin bottom surface and a vertical body which is integrally vertical and connected to the bottom surface, the overall dimension of the bottom surface is larger than that of the vertical body to form a crown shape, the vertical body penetrates through the positioning through hole of the box wall inwards to be limited to translate, and the crown-shaped bottom surface is clamped and fixed between the box wall and the supporting base surface to form an interlayer.

The improvement of the draw-bar is concentrated on the panel (also called big panel), the appearance surface is only added with the sound outlet, the sound outlet is represented as a local hole/seam, and the appearance and the color of the draw-bar box are hardly affected. The alarm support is simple in connection, even in the two forms of the b) and the c), and is applied to the existing draw-bar box assembly process, and the additional screw is not needed to be added for fixing, so that the production cost is saved, and the production cost comprises the material cost and the labor cost.

The alarm pull rod is considered to be matched with an alarm, and is characterized in that the alarm support of the alarm pull rod is also provided with an alarm which can be assembled and disassembled at any time, and a sound generating port of the alarm is close to or even embedded into a sound cavity of the alarm support to be communicated with the sound outlet. The alarm can be installed and disassembled at any time, is convenient to take out for charging, and can be carried along during air consignment (because the battery is arranged in the alarm and belongs to the articles prohibited for consignment). The sounding port of the alarm is close to or even embedded into the sound cavity of the alarm support to be communicated with the sound outlet, so that the alarm sound emitted by the alarm can be transmitted out of the sound outlet on the panel from the sound cavity channel of the alarm support, and the actual hearing effect of the alarm is generated outside the draw-bar box.

The utility model provides an alarm support which is used for supporting an alarm at the inner side of a pull rod panel in a pull rod box and comprises a light and thin bottom surface and a vertical body which is integrally vertical and connected to the bottom surface. This means, alarm support both can produce the circulation with the pull rod independently, can install with the general supporting of pull rod of different model colours again. A typical connector jack is known as a gold finger jack, but is not limited to just such a jack.

The alarm support is required to fix the wiring socket installed in the sinking groove seat, and is characterized in that the groove seat is provided with at least one pair of elastic groove buckles capable of clamping the socket which is matched with the embedding installation. The socket is clamped by the elastic groove buckle, so that the fixing by screws is avoided, the mounting process is simplified, and the production cost is saved.

Above-mentioned alarm support still needs can make things convenient for fixed mounting alarm, characterized by, erect the body structure and further include at least one elasticity in the periphery and press the knot, can form the extrusion centre gripping to the alarm casing of installing this perpendicular body and play and press from both sides tight fixed effect. Thus, the alarm can be conveniently assembled and disassembled at any time without screws.

The utility model provides an alarm which is used in a draw-bar box and is convenient to mount and dismount on the alarm support. By the arrangement, the indicator light can emit light outwards through the sound outlet to display a normal working duty state (such as intermittent slow flashing) and a flashing signal (such as rapid flashing) during alarming.

The alarm is inserted into the alarm support and needs to be matched with the shell structure, and is characterized in that buckling grooves are formed in two sides of the shell and are matched with the elastic pressing buckles of the alarm support in a matching mode. Therefore, when the alarm is inserted into the alarm support, the elastic pressing buckle on the alarm support is firstly squeezed open by applying a slight force, and then the buckling groove on the alarm meets the elastic pressing buckle on the alarm support to be compacted and fixed. When the alarm is pulled out, only a little force is needed.

The utility model provides an alarm draw-bar box based on the alarm draw-bar, an alarm support and an alarm, which comprises a box body, a draw bar, an alarm support and an alarm, and is characterized by comprising at least one of the following three items:
