Technical Field
The utility model belongs to the technical field of the relevant device of model head and specifically relates to a model head is with combination formula unable adjustment base is related to.
Background
The polyurethane model head is a model head made of foam plastic materials formed by foaming polyurethane materials, and in order to be fixed on a supporting base for supporting the model head, a base body is required to be fixed at the lower end of the model head to ensure that the model head can be fixed on the supporting base.
The main problem that exists of unable adjustment base of current model head lower extreme is: the existing fixing base is fixed with a model head by screws, but the effect of fixing the model head made of foam plastic by the screws is poor, so that the fixing base is easily separated from the model head.
Therefore, a combined fixing base for a model head is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model provides a model head is with combination formula unable adjustment base has increased fixed tooth and has come supplementary set screw to fix the model head, has adopted the structure of base body and clamping screw combination formula simultaneously, can select suitable clamping screw to make up as required, has solved the poor problem of fixed effect between unable adjustment base and the model head, has fixed reliable, the characteristics that the suitability is strong.
The technical scheme of the utility model is realized like this:
the combined type fixing base for the model head comprises a base body which is fixed at the lower end of the model head and coaxially arranged with the model head, wherein a fixing groove used for being inserted into the lower end of the model head is formed in the top of the base body, a boss is arranged on the bottom wall of the fixing groove, an installation through hole is formed in the middle of the boss in a penetrating mode, a fixing screw parallel to the axis direction of the base body penetrates through the installation through hole, a fixing nut is fixed on the fixing screw in a threaded mode, a plurality of fixing teeth are evenly distributed on the side wall of the fixing nut, an installation groove coaxially arranged with the installation through hole is formed in the bottom of the base body, the fixing screw stretches out of one end of the base body and is provided with an installation baffle, and the installation baffle is perpendicular to the fixing screw and is arranged in the installation groove.
As a preferred technical scheme, three square grooves extending along the axial direction of the fixed screw are arranged on the side wall of the fixed screw.
As a preferred technical scheme, a plurality of first threaded holes are formed in the boss in an annular penetrating mode, a plurality of second threaded holes matched with the first threaded holes are formed in the mounting baffle, and a fixing screw is fixedly arranged in each second threaded hole and the corresponding first threaded hole in a common threaded mode.
As a preferable technical solution, the number of the first threaded holes is the same as the number of the second threaded holes.
As a preferable technical scheme, an insertion groove for fixing the model head on the supporting base is arranged at the bottom of the fixing screw rod, and the insertion groove extends along the axial direction of the fixing screw rod.
By adopting the technical scheme, the beneficial effects of the utility model are that:
because the model head includes base body, clamping screw, fixation nut and fixed tooth with combination formula unable adjustment base, uses the utility model discloses a method as follows:
firstly, workers can select a proper fixing screw according to the depth of a groove at the bottom of a model head, if the groove is deep, a longer fixing screw can be selected to be combined with a base body, if the groove is shallow, a shorter fixing screw can be selected to be combined with the base body, then the selected fixing screw passes through an installation through hole on the base body, each first threaded hole is aligned with one second threaded hole, then a fixing nut is screwed on the fixing screw, and fixing teeth are adjusted to a proper position according to the depth of the groove at the bottom of the model head;
secondly, injecting a certain amount of polyurethane foaming agent into the groove at the bottom of the model head, rapidly sleeving the combined fixing base at the lower end of the model head, rapidly expanding the polyurethane foaming agent in the groove at the bottom of the model head and the fixing groove on the fixing base, contacting with water in the air to perform a curing reaction to form foamed plastic, wrapping the fixing screw, the fixing nut and the fixing teeth by the foamed plastic and fixing the fixing screw, the fixing nut and the fixing teeth, so that the model head and the fixing base are fixed, and simultaneously discharging the air in the groove at the bottom of the model head and the fixing groove through the first threaded hole and the second threaded hole in the expansion process of the polyurethane foaming agent;
and thirdly, after the polyurethane foaming agent is completely foamed and cured to form foamed plastic, screwing a plurality of fixing screws into the first threaded hole and the second threaded hole, and finally screwing the fixing screws into the foamed plastic to further fix the model head and the fixing base.
In the utility model, on the basis of fixing through the fixing screw, the fixing screw and the fixing teeth are added to assist the fixing screw to fix the model head and the fixing base, the contact surface between the side wall of the fixing teeth and the foamed plastic is very large, when the fixing screw has a tendency of rotation, the fixing teeth can provide a very large resistance to prevent the fixing screw from rotating, and meanwhile, the fixing screw is not only inserted into the foamed plastic for fixing, but also fixes the base body and the mounting baffle, so that the base body, the mounting baffle and the fixing screw are ensured not to rotate relatively, thereby solving the problem of poor fixing effect between the fixing base and the model head, and improving the reliability of fixing between the fixing base and the model head; and fixation screw's length can be selected according to the degree of depth of model head bottom recess, avoids appearing being greater than the degree of depth of first fixed recess because of fixation screw stretches into the length in the first fixed recess, and causes the unable cover of base to establish and be fixed in the condition of the lower extreme of model head body to guaranteed that the base can be firm throughout and model head body is fixed together, make no matter the degree of depth of model head bottom recess is dark shallow, the utility model provides a unable base all realizes fixedly with the model head, has improved the utility model discloses an applicability.
Because the outer side wall of the fixed screw is provided with three square grooves extending along the axial direction of the fixed screw, the fixed screw is cylindrical, although the side wall of the fixed screw is provided with threads, the contact surface between the fixed screw and polyurethane foam formed by polyurethane foaming agent is narrower, the fixed screw and the model head can rotate relatively easily when the model head is used for displaying, the rotation of the fixed screw can drive the fixed nut to rotate and move up and down and can also drive the fixed teeth to rotate, the movement of the fixed nut and the rotation of the fixed teeth can damage the polyurethane foam and seriously affect the fixation between the fixed base and the model head, so the width of the contact surface between the side wall of the fixed screw and the polyurethane foam is greatly increased by the square grooves arranged on the side wall of the fixed screw, and the probability of relative rotation between the fixed screw and the model head body is greatly reduced, the reliability of fixing the fixing screw is improved.
