Description
Technical field
The utility model relates to lamp stand technical field, is more particularly a kind of anti-loosening anticracking desk lamp lamp stand.
Background technology
Desk lamp lamp stand, for lamp holder is connected to lamp socket, and promotes lamp holder terrain clearance, expands lighting space.In the middle of real life, desk lamp lamp stand is that such way is easy to make screw periphery occur slight crack, finally splits and can not use directly by the middle of screw spiral to the screw of lamp socket.
Utility model content
The purpose of this utility model is to overcome the above defect of prior art, provides that a kind of structure is simple, easy to assembly, firmness is good, not easily loosens, is also convenient to the anti-loosening anticracking desk lamp lamp stand changed.
In order to reach above object, the utility model is achieved through the following technical solutions: a kind of anti-loosening anticracking desk lamp lamp stand, comprise in one there is post holes branch sleeve and one outside there is externally threaded mobile jib, it is characterized in that, a reinforcement sleeve is provided with in the post holes of described branch sleeve, there is in described reinforcement sleeve a screw matched with external screw thread on described mobile jib, the outside wall surface of described reinforcement sleeve is provided with some reinforcements vertically, reinforcing sleeve drum outer wall face described in adjacent two between reinforcement is formed with a groove, a snap fit is respectively arranged with in the groove of symmetry a pair wherein centered by the axle center of described reinforcement sleeve, the free end upper hookhead of described snap fit exposes outside described groove, the post holes internal face of described branch sleeve is provided with the hole clipping matched with snap fit described in two for a pair.
As preferably, the post holes internal face of described branch sleeve is provided with a pair along its axial arranged gathering sill, gathering sill described in each is corresponding to hole clipping described in.
As preferably, the screw strengthening sleeve exports in circumference and is provided with a step groove, described step groove has been embedded in a pad, the outer rim of described pad is provided with the fixing pin be arranged symmetrically with for a pair, the inner edge of described step groove is provided with the position-arresting groove adapting to described fixing pin for a pair; The centre bore inner edge of described pad is provided with the spline limit be arranged symmetrically with for a pair, correspondingly stretches into the spline plane paragraph in the screw of described reinforcement sleeve being provided with and matching with described spline limit for a pair at mobile jib.
As preferably, described mobile jib is also provided with a locking nut matched with described pad.
Beneficial effect: (1) the utility model mobile jib is not directly connected on lamp socket by thread forms, but linked again on lamp socket by the reinforcement sleeve of an outer field branch sleeve and internal layer, through overlapping mobile jib layer by layer, injury like this for installing hole on lamp socket is just very little, no longer easily splits.Branch sleeve and strengthen sleeve be by snap fit and hole clipping in mating connection, instead of the tight fit of routine, such guarantee can not loosen, also ensure relative to not rotating, moreover reinforcement sleeve is provided with reinforcement, not only make that there is between sleeve deformation gap, can not to rise pyrocondensation and racking each other because of heat, while ensureing that firmness is good, be also convenient to change.
(2) strengthen after in sleeve when mobile jib is threaded into, then by the spline limit of pad and the spline plane of mobile jib inconsistent, make both keep static, again pad is pressed as in step groove, with locking nut locking, mobile jib is wanted to have rotated all not easily, fully ensure that mobile jib does not loosen.

Detailed description of the invention
In order to make technological means of the present utility model, creation characteristic and reach object be easy to understand understand, set forth the utility model further below in conjunction with specific embodiment.
Embodiment: as shown in Figure 1, a kind of anti-loosening anticracking desk lamp lamp stand, comprise in one there is post holes 12 branch sleeve 1 and one outside there is externally threaded mobile jib 2, be provided with a reinforcement sleeve 3 in the post holes 12 of branch sleeve 1, strengthen that there is in sleeve 3 screw 34 matched with external screw thread on mobile jib 2.
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the outside wall surface of reinforcement sleeve 3 is provided with four reinforcements 31 vertically, reinforcement sleeve 3 outside wall surface between adjacent two reinforcements 31 is formed with a groove 32, a snap fit 33 is respectively arranged with in the groove 32 of symmetry a pair wherein centered by the axle center strengthening sleeve 31, the free end upper hookhead of snap fit 33 exposes outside groove 32, post holes 12 internal face of branch sleeve 1 is provided with the hole clipping 11 matched with two snap fits 33 for a pair.Post holes 12 internal face of branch sleeve 1 is provided with a pair along its axial arranged gathering sill 13, each gathering sill 13 correspondence is through a hole clipping 11.
As shown in Figure 7 and Figure 8, the screw 34 strengthening sleeve 3 exports in circumference and is provided with a step groove 35, step groove 35 has been embedded in a pad 37, the outer rim of pad 37 is provided with the fixing pin 38 be arranged symmetrically with for a pair, the inner edge of step groove 35 is provided with the position-arresting groove 36 adapting to fixing pin 38 for a pair; The centre bore inner edge of pad 37 is provided with the spline limit 39 be arranged symmetrically with for a pair, the paragraph correspondingly in mobile jib 2 stretches into the screw 34 strengthening sleeve 3 is provided with the spline plane 21 matched with spline limit 39 for a pair.Mobile jib 2 is also provided with a locking nut 4 matched with pad 37.
Practical: first reinforcement sleeve to be pressed in branch sleeve, for making snap fit find hole clipping smoothly, slipping into from snap fit alignment guide groove, and then on mobile jib, overlapping Upper gasket and nut, ensure that mobile jib screws in the abundant distance strengthening sleeve, strengthen after in sleeve when mobile jib is threaded into, then by the spline limit of pad and the spline plane of mobile jib inconsistent, make both keep static, again pad is pressed as in step groove, with locking nut locking, mobile jib is wanted to have rotated all not easily, fully ensure that mobile jib does not loosen.
