Abstract
The utility model relates to a rectangular mast lifting component comprising a first mast, a second mast, a third mast...and an N<th> mast which are sequentially sleeved from inside to outside, wherein the N is larger than or equal to 3. Two adjacent masts are slidably sleeved, two 'L'-shaped nylon blocks are arranged on the first mast and fixed to opposite angles of the first mast respectively, inner right angles of the 'L'-shaped nylon blocks are matched with exterior angles of the first mast, the length of each of four sides of the cross section of the first mast is d1, the length of each of two inner right-angle sides of each 'L'-shaped nylon block is d2, and the d2 is larger than 0.6*(d1/2). The rectangular mast lifting component effectively stops top masts from rotating relatively.
Description
Technical field
The utility model relates to a kind of rectangle mast lifting assembly, belongs to the beacon lighting technical field.
Background technology
Existing mast mouth design is also to adopt the nylon block diagonal angle distribution limitation free degree, but when a few joint of mast top, often due to the reason (large percentage of R and d1) at the R angle of the rectangle section bar used, the relative motion that can rotate, very dangerous, even the effect that nylon block does not all reach has all been installed at four angles.
The utility model content
The purpose of this utility model is to overcome the defect that prior art exists, and mast rectangle mast lifting assembly in relative rotation in a kind of effective prevention top is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of rectangle mast lifting assembly, by the first segment mast, the second section mast, the 3rd joint mast, N joint mast is socket formation successively from inside to outside, N>=3, between described two adjacent masts, be slidably socketed, be provided with " L " type nylon block on described first segment mast, should be provided with two by " L " type nylon block, be separately fixed on the diagonal angle of first segment mast, the interior right angle that is somebody's turn to do " L " type nylon block matches with the exterior angle of first segment mast, the length of the four edges of the cross section of described first segment mast is d1, the length of two interior right-angle sides of " L " type nylon block is d2, and d2 > 0.6 * (d1/2).
Described second section mast top is equipped with position two bracing frames corresponding with above-mentioned two " L " type nylon block respectively, and described two " L " type nylon block is separately fixed on this two bracing frame.
Beneficial effect: the utility model has solved the defect existed in the background technology, increased L " length d 1 of two interior right-angle sides of type nylon block; use like this two nylon blocks just can effectively stop the top mast to relatively rotate; to use safer; reached better effect; simple in structure, safety, reliable, be easy to application.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
A kind of rectangle mast lifting assembly as shown in Figure 1, 2, by first segment mast 1, second section mast 2, the 3rd joint mast ..., N joint mast from inside to outside successively socket form, N>=3, be slidably socketed between described two adjacent masts.Be provided with " L " type nylon block 3 on described first segment mast 1, should be provided with two by " L " type nylon block 3, be separately fixed on the diagonal angle of first segment mast 1, the interior right angle that is somebody's turn to do " L " type nylon block 3 matches with the exterior angle of first segment mast 1.Described second section mast 2 tops be equipped with position respectively two bracing frame 4, two " L " type nylon blocks 3 corresponding with two " L " type nylon block 3 be separately fixed on this two bracing frame 4.The length of the four edges of the cross section of described first segment mast 1 is d1, and the length of two interior right-angle sides of " L " type nylon block 3 is d2, and d2 > 0.6 * (d1/2).
Should be appreciated that specific embodiment described above is only for explaining the utility model, and be not used in restriction the utility model.The apparent variation of being extended out by spirit of the present utility model or change are still among protection domain of the present utility model.
