Abstract

The utility model discloses a padlock capable of transmitting radio signals, which relates to an anti-theft lock. The product mainly turns an ordinary lock beam into a switch type special lock beam (1); a signal transmitter (13) and a light-touch type press-open switch (K) are added in a lock body (21). The light-touch type press-open switch (K) is composed of a hollow copper screw (8), an insulating rubber pipe (7), a movable copper arm (9), a pressure spring (11) and an insulating rubber pipe (10). The utility model has the primary advantage that the defect that the lock beam is not easy to find to be hinged and pried or opened is avoided. The padlock capable of transmitting radio signals is an ideal anti-theft product for people.

Description

The wireless signal transmission padlock

The utility model relates to theftproof lock, and particularly a kind of padlock of wireless signal transmission is the security device of family, warehouse and vehicle.

In order to strengthen people's property safety problem, people have made various lock series products.Can still keep away the key that unavoidable some lock bridge cut with scissors or duplicate and open, people's property can't be protected.Also stayed the leak of setting about simultaneously to the robber.

The lock that also has some to have warning device now, but its complex structure costs an arm and a leg, and is not suitable for the particularly instructions for use in rural area of general family.

The purpose of this utility model promptly is to keep away unavoidably by sled, cut with scissors at above-mentioned existing general lock, and has the lock construction complexity of warning device, the problem of aspect such as cost an arm and a leg, and a kind of wireless signal transmission padlock of simple in structure, low cost is provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of wireless signal transmission padlock, comprise lock body (21), dead bolt (22), lock cylinder (23), lock bridge (1) is housed on lock body (21), lock bridge (1) is hollow, lead (2) is equipped with in inside, and isolator (3) is housed, and be provided with contact (4) at the top of lock fine strain of millet (1) opening end, in the lock body of bottom, contact (4), be provided with light-duty pressure breakdown and close (K); Battery (15) and signal projector (13) also are housed in lock body (21), are provided with battery cover board (6) on battery (15) top.Light-duty pressure breakdown closes (K) mainly to be made up of hollow brass screws (8), insulation rubber tube (7), active copper arm (9), insulation rubber tube (10) and compression spring (11), its hollow core brass screws is to be fixed on the battery cover board (6), and has added airtight water seal circle (5) between lock bridge (1) opening end and hollow brass screws (8).Airtight water seal circle (14) is housed between battery cover board (6) and battery hole.Lead (12) with a tape insulation skin between active copper arm (9) and signal projector (13) is connected.In battery (15) bottom stage clip (16) and insulator foot (17) are installed, stage clip (16) is connected with signal projector (13) by the lead of tape insulation skin.

The utlity model has following advantage and effect:

For people's property can fully be ensured, the special signal transmitting system that in lock body, is equipped with.The power supply of transmitter (in establish coding circuit) adopts dry cell to supply with, and is convenient in order to change battery, prevents that again the robber from destroying simultaneously, and the fixed screw of battery cover board is arranged in the lock body of lock bridge opening end bottom.Be difficult for realizing this shortcoming for fear of lock bridge by hinge, lock bridge adopts the hollow type, and has injected the lead of a tape insulation skin in the centre, thereby constitutes a kind of special switching mode lock bridge; For fear of the robber unblank, picking lock is difficult for realizing this shortcoming, the special type that touches that is provided with in the lock body of the bottom of lock bridge opening end presses breakdown to close, its structure is made of jointly hollow brass screws, insulation rubber tube, active copper arm and compression spring.Under the cooperation of above several parts, just constituted the complete emission system of a cover.

The advantage of this utility model: build is elegant in appearance, and is safe and convenient to use; Avoided lock bridge to be cut with scissors, prized and locked to be opened being difficult for realizing this especially big shortcoming; Applied range; Owing to adopt coding-decoding circuit, signal changes can reach kind more than 15000, and a receiver can receive the of the same race of many same signals and transmit, and receiving range can reach hundred meters distant, and power consumption is minimum, once changes electricity, available half a year.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structure chart of wireless signal transmission padlock of the present utility model

Fig. 2 is the A-A sectional view of Fig. 1

Be described further below in conjunction with drawings and Examples:

Shown in Figure 1, wireless signal transmission padlock of the present utility model is the same with general padlock, it also has lock body 21, dead bolt 22, lock cylinder 23, lock bridge 1 is housed on lock body 21, lock bridge 1 is hollow, lead 2 is equipped with in inside, and isolator 3 is housed, top at lock bridge 1 opening end is provided with contact 4, being provided with the type that touches in the 4 bottom lock bodies of contact presses breakdown to close K, this touches type and presses breakdown to close K mainly by hollow brass screws 8, insulation rubber tube 7, active copper arm 9, insulation rubber tube 10 and compression spring 11 are formed, and are equipped with airtight water seal circle 5 between lock bridge 1 opening end and hollow brass screws 8.

Shown in Figure 2, battery 15 and signal projector 13 also are housed in lock body 21, be provided with battery cover board 6 on battery 15 tops, hollow brass screws 8 is fixed on above the battery cover board 6 and plays the effect of self-contained battery cover plate 6, airtight water seal circle 14 is housed between battery cover board 6 and battery hole, lead 12 with a tape insulation skin between active copper arm 9 and the signal projector 13 is connected, in battery 15 bottoms stage clip 16 and insulator foot 17 are installed, stage clip 16 is connected with signal projector 13 by the lead 18 of tape insulation skin, seals with sealing compound 20 around the signal projector antenna 19.

Be operating principle below:

From Figure of description as can be seen: the positive electricity of battery 15 is connected with the positive terminal of lead 18 with signal projector 13 by battery spring 16, and battery spring 16 has been equipped with insulator foot 17, is used for completely cutting off being connected of positive electricity and lock body shell 21.The negative electricity of battery 15 is connected with metal lock body shell 21 with hollow brass screws 8 by battery cover board 6, so lock body shell 21 has also just become the negative electricity of battery.Between battery gland 6 and battery hole, added airtight water seal circle 14, immersed battery hole to prevent humidity, and damage battery.When lock is in closure state,, damage switch to prevent humidity because pressing down of lock bridge 1 will compress airtight water seal circle 5.Because pressing down of lock bridge 1 forces the contact 4 of lead 2 to contact with active copper arm 9 again, again hollow brass screws 8 and active copper arm 9 are separated simultaneously; In order not allow active copper arm 9 contact, between them, added insulation tube 7 with hollow brass screws 8.Because the negative electricity end of signal projector 13 is connected with active copper arm 9 by lead 12, again because lock body is the battery negative electricity, lock bridge 1 and lock body are one, so lock bridge 1 also becomes the battery negative electricity, at this moment, as remove to cut off lock bridge 1 with cutting nippers, lock bridge 1 and lead 2 will inevitably pass through the metal cutting nippers and the moment conducting so, thereby constitute signal projector 13 negative electricity conductings and work, make signal projector 13 send signal by antenna 19.When lock is opened, owing to there is not the pressure of lock bridge 1, active copper arm 9 will make active copper arm 9 and hollow brass screws 8 closures by the elastic force of spring 11, thereby make signal projector 13 negative electricity conductings and work, send signal, contact with lock body shell 21 for fear of spring 11, between them, added sealing compound base 10.
