Description
Technical Field
[0001] The utility model relates to the field of mechanical anti-theft door locks, and in particular to a device for realizing a quick anti-locking function outside a door. Background Art
[0002] In today's residential security environment, the widespread use of inward-opening entrance doors has aroused widespread concern about their safety. According to surveys, most families have this type of door. Their original design may be for easy opening and closing, but the reality is that this type of door often has certain defects and is unable to cope with technical unlocking.
[0003] In order to enhance security, many families have begun to choose more solid outward-opening entrance doors, or smart door locks equipped with advanced locks and alarms. However, even these high-tech products cannot completely prevent burglary. The most effective way to solve this problem is to lock the door after closing it. It is easy to lock the door indoors, but it must be locked outdoors with a key. Every time you go out, you have to press the elevator, find the key, take out the key, insert the key, turn the key, lock the door, and remove the key. The process is complicated and cumbersome. If there is a problem with any of the procedures, there will be safety hazards. Summary of the invention
[0004] According to the problems of the traditional door lock in use, a device for realizing the function of fast anti-locking from outside the door is provided. The utility model realizes anti-locking of the door by pressing the knob to make the rotating mechanism with gears on both sides contact and rotate, thereby realizing anti-locking of the door by simply pressing the anti-locking button of the door lock once, simplifying the process and saving time.
[0005] The technical means adopted by the utility model are as follows:
[0006] A device for realizing a quick anti-locking function outside a door, comprising: an outer door housing of a door lock, a door lock body, an inner housing of a door lock, an outer door pressing knob, a spring, a one-way rotating ratchet, a rotating shaft, a rotating mechanism, an anti-locking slot, an inner door anti-locking knob, and an inner door anti-locking transmission steel bar;
[0007] The outside door push knob is connected to one side of the rotating mechanism through the spring and the rotating shaft, the one-way rotating ratchet is installed on the rotating shaft, and the inside door anti-lock button on the inside door side is connected to the rotating mechanism with gears through the anti-lock transmission steel bar.
[0008] Furthermore, the one-way rotating ratchet can only rotate forward and cannot rotate reversely.
[0009] Furthermore, the rotating mechanisms with gears on both sides can only be rotated by contacting a push knob outside the door or an anti-lock knob inside the door.
[0010] Furthermore, the door is locked by using the locking button or key.
[0011] Furthermore, the door is locked by pressing the door knob outside.
[0012] Due to the adoption of the above technical solution, compared with the prior art, the utility model has the following advantages:
[0013] 1. The present invention provides a device for realizing a quick anti-locking function outside a door. Compared with the commonly used single-active, double-active, and single-active double-fast door locks, the present design has a quick anti-locking function that can be realized outdoors without a key, which is not available in the common single-active, double-active, and single-active double-fast door locks.
[0014] 2. The present invention provides a device for realizing the function of fast anti-locking outside the door. Compared with the automatic anti-locking lock body, because it can be indiscriminately anti-locked as long as the door is opened or closed, the present design has the selectivity that the latter does not have, and it can not be anti-locked in the scene where anti-locking is not needed, which is more flexible.
[0015] 3. The present invention provides a device for realizing the function of fast anti-locking outside the door. By turning a knob, the anti-locking function can only be realized outside the door, but the anti-locking function cannot be released, which will not cause safety hazards.
[0016] 4. The present invention provides a device for realizing the function of fast anti-locking outside the door. Under normal circumstances, the device has no contact with the original lock body. Even if the device is damaged, the one-button anti-locking function will be invalid, and other functions of the lock body will not be affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0026] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0027] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0029] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0030] like Figures 1 to 4 As shown, the utility model provides a device for realizing the fast anti-locking function outside the door, comprising: a door lock outer shell 1, a door lock body 2, a door lock inner shell 3, an outer door pressing knob 4, a spring 5, a one-way rotating ratchet 6, a rotating shaft 7, a rotating mechanism, an anti-locking slot 10, an inner door anti-locking knob 11, and an inner door anti-locking transmission steel bar 12;
[0031] The outside door push knob 4 is connected to one side of the rotating mechanism through the spring 5 and the rotating shaft 7, and the one-way rotating ratchet is installed on the rotating shaft. The inside door anti-lock button 10 on the inside door side is connected to the rotating mechanism with gears through the anti-lock transmission steel bar 12.
[0032] Furthermore, the outside door push knob 4 and the inside door anti-lock knob 11 both protrude from the door lock outer shell 1 and the door lock inner shell 3. The overall lock body structure is located between the door lock outer shell 1 and the door lock inner shell 3. The outside door push knob 4 is connected to the rotating shaft 7 through a spring 5 and a one-way ratchet 6. A rotating mechanism 8 with a gear on the outside of the door is provided at the tail end of the rotating shaft 7. By pressing and rotating the outside door push knob 4, the rotating mechanism 8 with a gear on the outside of the door contacts and rotates with the rotating mechanism 9 with a gear on the inside of the door, driving the anti-lock slot 10 to rotate, thereby realizing the outside door anti-lock function. The inside door anti-lock button 11 is connected to the anti-lock slot 10 through the inside door anti-lock transmission steel bar 12. The inside door anti-lock is realized by rotating the inside door anti-lock knob 11 inside the door to drive the anti-lock slot 10.
[0033] Furthermore, the anti-lock function can be achieved using the door knob 11 or a key. The door anti-lock button 11 can be rotated counterclockwise or with a key. At this time, due to the action of the spring 5, the door outer rotating mechanism 8 and the door inner rotating mechanism 9 are not in contact, and the function can be achieved normally.
[0034] Further, the door can be locked or unlocked with a key, the door can be locked by turning the door lock button 11 clockwise or turning it with a key. At this time, due to the action of the spring 5, the door outer rotating mechanism 8 and the door inner rotating mechanism 9 are not in contact, and the function can be realized normally. Use the door outer key to lock or unlock. At this time, due to the action of the spring 5, the door outer rotating mechanism 8 and the door inner rotating mechanism 9 are not in contact, and the operation is normal, and the function can be realized normally.
[0035] Further, to lock the door, use the outside door knob. Press the outside door pressing knob 4. At this time, the spring 5 is compressed, causing the gear parts of the door outside rotating mechanism 8 and the door inside rotating mechanism 9 to contact and engage. Then, turn the outside door pressing knob 4 clockwise to drive the door inside rotating mechanism 9, and drive the anti-lock slot 10, the door inside anti-lock button 11 and the door inside anti-lock transmission steel bar 12 to rotate together, so as to achieve the door outside anti-lock function. After rotating into position, the knob will not rotate anymore. Release the outside door pressing knob 4 to achieve the anti-lock purpose. At this time, the spring rebounds to pull the door outside rotating mechanism 8 and the door inside rotating mechanism 9 apart. If it does not reach into position at one time, you can repeat this action until it cannot rotate anymore.
[0036] Furthermore, the one-way rotating ratchet wheel 6 can only rotate in the forward direction and cannot rotate in the reverse direction.
[0037] Furthermore, the rotating mechanisms with gears on both sides can only be rotated by pressing the knob 4 outside the door or contacting the anti-locking knob 11 inside the door.
[0038] Furthermore, the door is locked by using the locking button or key.
[0039] Furthermore, the door is locked by pressing the door knob outside.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
