Abstract
The utility model relates to a kind of cage knob, refers to the cage knob that can prevent key from extracting at errors present very well especially.The utility model is by the following technical solutions: a kind of cage knob that can prevent key from extracting at errors present very well, it is characterized in that: described lock tube assembly includes lock tube and two panels metal clips, the medial surface of lock tube includes two and becomes symmetrically arranged arc surface, two sockets inserted for locking plate top are respectively arranged with between two arc surfaces, the both sides of socket are provided with slot, the below of described arc surface is provided with boss, the both sides of described metal clips are extended straight flange, described two panels metal clips is fixedly fitted on two arc surfaces of lock tube respectively, the both sides of metal clips are corresponding to be respectively plugged in slot, on the boss of the downside conflict of metal clips.By adopting such scheme, the utility model provides a kind of contact area increasing locking plate and lock tube, improves the intensity of lock tube, makes key not easily from the cage knob that the opposite way round is extracted.
Description
Technical field
The utility model relates to a kind of cage knob, refers to the cage knob that can prevent key from extracting at errors present very well especially.
Background technology
The existing key that can prevent very well includes lock tube and lock core at the lock that errors present is extracted, two (inceptive directions locked by key, an operative orientation) or three (inceptive directions, two operative orientations) stagnate position, one of them is inceptive direction, key can plug smoothly, remaining is operative orientation, key cannot be extracted, and lock controls the plug orientation of key by lock tube, key is when the position of mistake is extracted, and key drives locking plate to withstand on lock tube, and key cannot be extracted.Existing plastics lock tube intensity is less, and simultaneously less in the contact area of lock operative orientation lock tube and locking plate, when key is extracted, locking plate easily sticks into lock tube, causes key easily to be extracted from the direction of mistake.In latching operation process, if client uses larger power to extract key from the direction of mistake, cause lock function to lose efficacy, make equipment keep undesirable duty, the consequence of device damage and casualties time serious, may be caused.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, and provides a kind of contact area adding locking plate and lock tube, improves the intensity of lock tube, makes key not easily extract cage knob from the direction of mistake.
To achieve these goals, the utility model is by the following technical solutions: a kind of cage knob that can prevent key from extracting at errors present very well, include lock tube assembly and lock core, described lock core is provided with locking plate and spring, lock core is provided with in the through hole of lock tube assembly, it is characterized in that: described lock tube assembly includes lock tube and two panels metal clips, described lock tube is axially symmetric structure, the medial surface of lock tube includes two and becomes symmetrically arranged arc surface, two sockets inserted for locking plate top are respectively arranged with between two arc surfaces, the both sides of socket are provided with slot, the below of described arc surface is provided with boss, the whole camber of described metal clips, the both sides of metal clips are extended straight flange, described two panels metal clips is fixedly fitted on two arc surfaces of lock tube respectively, the both sides of metal clips are corresponding to be respectively plugged in slot, on the boss of the downside conflict of metal clips.
By adopting such scheme, metal clips is provided with inside lock tube of the present utility model, such key locking plate when other positions has been conflicted on metal clips, add the contact area of locking plate and metal clips, metal clips is whole in addition conflicts with the arc surface of lock tube, substantially increases the intensity of metal clips like this, key is not easily extracted from the direction of mistake, namely use very large power to be also not easy to extract, realize the uniqueness that direction extracted by key.
Further setting of the present utility model is: the middle part of described lock tube boss is provided with reference column, the below of described metal clips is provided with the recess coordinated with reference column, the recess of metal clips is plugged in and reference column realizes being fixedly connected with of metal clips and lock tube, and the outside that described lock tube is positioned at two arc surfaces is respectively arranged with strengthens convex footpath; The width of described boss is identical with the thickness of metal clips, and two, the below drift angle of described metal clips becomes chamfering to arrange.
By the scheme arranged further, the further optimization that the utility model is implemented, the wherein stability that guarantee metal clips is further set of reference column, the outside that lock tube is positioned at two arc surfaces is respectively arranged with to be strengthened arranging of convex footpath and can play a supporting role to metal clips, chamfering the installation that can facilitate metal clips is set.
Newly be described in further detail originally practical below in conjunction with accompanying drawing.

Detailed description of the invention
As Figure 1-Figure 5, a kind of cage knob that can prevent key from extracting at errors present very well, include lock tube assembly 1 and lock core 2, described lock core 2 is provided with locking plate 21 and spring 22, lock core 2 is provided with in the through hole 13 of lock tube assembly 1, in the utility model embodiment, described lock tube assembly 1 includes lock tube 11 and two panels metal clips 12, described lock tube 11 is axially symmetric structure, the medial surface of lock tube 11 includes two and becomes symmetrically arranged arc surface 111, two sockets 112 inserted for locking plate 21 top are respectively arranged with between two arc surfaces 111, the both sides of socket 112 are provided with slot 1121, the below of described arc surface 111 is provided with boss 113, the whole camber of described metal clips 12, the both sides of metal clips 12 are extended straight flange 121, described two panels metal clips 12 is fixedly fitted on two arc surfaces 111 of lock tube 11 respectively, the both sides 121 of metal clips 12 are corresponding to be respectively plugged in slot 112, on the boss 113 of the downside conflict of metal clips 12, by adopting such scheme, metal clips 12 is provided with inside lock tube 11 of the present utility model, such key locking plate when other positions has been conflicted on metal clips 12, add the contact area of locking plate 21 and metal clips 12, metal clips 12 is whole in addition conflicts with the arc surface of lock tube 11, substantially increases the intensity of metal clips 11 like this, key is not easily extracted from the direction of mistake, namely use very large power to be also not easy to extract, realize the uniqueness that direction extracted by key.
In the utility model embodiment, the middle part of described lock tube boss 113 is provided with reference column 1131, the below of described metal clips 12 is provided with the recess 122 coordinated with reference column 1131, the recess 122 of metal clips 12 is plugged in being fixedly connected with of reference column 1131 realizing metal clips 12 overlaps with lock 11, the stability of so further guarantee metal clips 12, the outside that described lock tube 11 is positioned at two arc surfaces 111 is respectively arranged with the convex footpath 114 of reinforcement, can play a supporting role like this to metal clips 12; The width of described boss 113 is identical with the thickness of metal clips 12, and two, the below of described metal clips 12 drift angle 123 one-tenth chamfering is arranged, chamfering 123 the installation that can facilitate metal clips 12 is set.
