Description

Anti-theft lockset of student residence

Technical field

The present invention relates to a kind of lockset, in particular, relate in particular to a kind of lock that is applied in the student dormitory and is easy to change padlock.

Background technology

At present, student's life is convenient to change and make things convenient for for reducing management cost in school; Most dormitory door locks are padlock; The door nose is steel plate or reinforcing bar hanging nose, because of lock and door nose expose, picking lock takes place often or cut off the stolen incident of a nose; Brought very big inconvenience not only for the management of school, but also student's property has been caused infringement.

Summary of the invention

The present invention provides an a kind of pick-proof lock and the anti-anti-theft lockset of student residence of nose structure of cutting of being provided with in order to overcome the shortcoming of above-mentioned technical problem.

Anti-theft lockset of student residence of the present invention; Comprise that first nose and second nose of being individually fixed on doorframe and the door reach and two door locks that the door nose is used; Its special feature is: described first nose comprises afterbody, stem and is connected afterbody and the middle part of stem; Described afterbody and stem are positioned at the both sides on plane, middle part place, and described middle part offers the some mider holes that are used for fixing first nose, have on the described stem on the side of lockhole and stem and are fixed with arc; Described second nose comprises second afterbody, second stem and is connected second afterbody and second middle part of second stem; Described second afterbody and second stem are positioned at the same side on plane, place, second middle part; Offer some second mider holes that are used for fixing second nose on described second middle part, have second lockhole that matches with lockhole on described second stem; Described door lock comprises lock body and lock, and the fixed end of said lock is provided with arc first backplate that is symmetric shape, and movable end one side of said lock is provided with second backplate of arc, forms the backplate breach between described first backplate and second backplate.The described mider hole and second mider hole are respectively applied for fixing first nose and second nose, and the arc that is arranged on the stem outside is used for protection lock and hangs over the door lock on the lockhole, prevents that door lock from being prized, and said arc can cover whole sides and whole top margins of stem; The afterbody and second afterbody are set prevent effectively that first nose and second nose from being extracted out from crack between a door and its frame.First backplate that shields and second backplate are set around the lock of door lock can be prevented more effectively that door lock from being prized and cut.

Anti-theft lockset of student residence of the present invention, described stem is provided with breach, and said breach is positioned at the below of lockhole; Second stem of described second nose is provided with second breach, and said second breach is positioned at the below of second lockhole.The breach and second breach are set can be used with the door lock that has backplate, makes lock be blocked fully in the inside of arc, is of value to the protection door lock more.

Anti-theft lockset of student residence of the present invention, the angle at said afterbody and middle part are 90 °, and the angle at described second afterbody and second middle part is 90 °.Adopt afterbody and the perpendicular form in middle part to help fixing first nose and second nose more.

Anti-theft lockset of student residence of the present invention, the angle at said first nose stem and middle part is 100～160 °, the angle at said second stem and second middle part is 100～160 °.

Anti-theft lockset of student residence of the present invention, the described afterbody and second afterbody have had two afterbody holes and two second afterbody holes of fixation, and the quantity of the said mider hole and second mider hole is three and distribution triangular in shape.Adopt all fixing fixed structure form in afterbody and middle part and second afterbody and middle part, fixing first nose and second nose that can be more firm.

The invention has the beneficial effects as follows: said first nose adopts S shape, and second nose adopts L shaped form of structure, makes that the door nose is more firm; The door nose is provided with arc and can prevents effectively that door lock from being prized and cut; The lock of the door lock that is used with the door nose is provided with first backplate and second backplate, has further strengthened the fastness of lockset of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described further.

Fig. 1, Fig. 2 and Fig. 3 are and first kind of structural representation that embodiment is relevant; Fig. 4, Fig. 5 and Fig. 6 are and second kind of structural representation that embodiment is relevant; The difference of first kind of embodiment lockset and second kind of embodiment lockset is; First kind of embodiment is applied in the open the door situation of (people stands outside the door, and sees towards door) of right side, and second kind of embodiment is applied in the situation of opening the door in the left side.

Embodiment 1; As shown in Figure 1; First shown nose 1 comprise afterbody 2, stem 4 and be connected the middle part 3 of afterbody 2 and stem 4, and shown afterbody 2 and stem 4 are positioned at the both sides on plane, 3 place, middle part, and the vertical and afterbody 2 in shown afterbody 2 and middle part 3 is provided with two afterbody holes 6 of matching with bolt; Shown middle part 3 is provided with the mider hole that matches with bolt 7 of three distributions triangular in shape; Shown stem 4 and the angle between the middle part 3 are 135 °, and the central part of shown stem 4 is provided with a lockhole 8, and the below of shown lockhole 8 is provided with rectangle breach 9; The curved surface of forming a circular shape on the side of shown stem 4 and the end face; Be fixed with arc 5 on this curved surface, this arc 5 has covered the whole side and the whole top of stem, and the curved surface at the normal on plane, stem 4 place and arc 5 places parallels.

As shown in Figure 2; Second shown nose 10 comprises second afterbody 11, second stem 13 and is connected second middle part 12 of 10 ones of second afterbodys and second stem 13; The second shown afterbody 11 and second stem 13 are positioned at the same side on plane, 12 place, second middle part; Shown second afterbody 11 and second middle part are perpendicular; Have the length at two 6, the second middle parts 12, afterbody hole of matching and the equal in length at first nose middle part 3 on second afterbody, and offer second mider hole 15 of three distributions triangular in shape on second middle part 12 with bolt; The shape of the second shown stem 13 is identical with the shape of first nose stem 4; The central part of second stem 13 offers second lockhole 16, and the below of this second lockhole 16 offers rectangular second breach 17, and the second shown lockhole 16 is corresponding with the position of lockhole 8 and breach 9 respectively with second breach 17.

As shown in Figure 3, the structural representation when Fig. 3 has provided the use of embodiment 1 can be known that by Fig. 3 first shown nose 1 is fixed on the doorframe, and second nose 10 is fixed on the door, and after door was closed, its state was as shown in Figure 3, and locking then gets final product.

Embodiment 2; Fig. 4, Fig. 5 and Fig. 6 have provided the structural representation of second kind of embodiment, and the structure of first nose 1 shown in Figure 4 is identical with the structure of first nose described in the embodiment 1, and second nose 10 shown in Figure 5 is also identical with the structure of second nose shown in the embodiment 1; Structural representation during the use of embodiment 2 as shown in Figure 6; First shown nose 1 is fixed on the doorframe, and second shown nose 10 is fixed on the door, after door closes well; Its state is as shown in Figure 6, and locking then gets final product.
