Abstract

The utility model discloses a connection structure for a leg force arm at the front end of a weight lifting bed and a front upright beam; the top of the front upright beam extends forwards to be fixedly connected U-shaped connector; a bent force arm is hinged at the front end of the opened side of the connector; the force arm is hinged with the U-shaped connector by a sheathing bolt; and the sheathing bolt comprises an internal-thread spiral pipe and a screw which is matched therewith. The weight lifting bed in the utility model adopts the internal-thread spiral pipe which is matched with the U-shaped connector in the aspect of width, so that the joint between the leg force arm and the U-shaped connector is elastic properly to achieve smooth and free rotation and the assembling difficulty is reduced; and by means of round caps at two ends of the screw and the spiral pipe, the users can be protected against unexpected scratch. Through elaborate and chic design at details, humanized care for the users is fully embodied, the safety is further considered and the psychological feelings of the users are concerned.

Description

The weight bench front end shank arm of force and preceding upright beam syndeton

Technical field

The utility model relates to a kind of health and fitness facilities, particularly a kind of weight bench.

Background technology

Along with growth in the living standard, people also more and more pay attention to healthy maintenance, and sport and body-building has become in people's daily life must an obligato part; Common health and fitness facilities function singleness, daily exercise is more uninteresting, when tempering disparity items; Need to change body-building apparatus, make that like this exercise is comparatively loaded down with trivial details, often be not easy to adhere to getting off; And deal with improperly simultaneously and can cause problems such as pulled muscle, sports fatigue; Much human persistently but produces little effect to losing weight; Dangerous again as rehabilitation training.

The weight bench series products is extensively popular with users as the many products of a kind of exercise mode simple in structure; But the connecting mode of its anterior shank training position and preceding upright beam uses plain bolt usually; And with common stop nut locking; Though can reach the normal rotation function when using, when stop nut is locked too tight or too loosely, all can influence the smooth and easy of rotation, thereby influence result of use.Simultaneously, the plain bolt part of stretching out nut is easy to scratch the user.

The utility model content

The utility model technical problem to be solved is, provides a kind of raising shank training department to rotate smoothness, prevents the guest too tight or too loose weight bench front end shank arm of force and syndeton of preceding upright beam when these parts are installed.

To achieve these goals, the technical scheme of the utility model is following:

A kind of weight bench front end shank arm of force and preceding upright beam syndeton; Be fixedly connected with the U-shaped connector in preceding upright back portion with extending forward; At the hinged arm of force that is provided with bending shape of the open side front end of described connector; The hinged employing suit bolt of the described arm of force and U-shaped connector, described suit bolt comprise internal thread Luo pipe and with the screw of its coupling.

Preferably, described suit bolt can effectively avoid the user to be scratched by nut for circle cap internal thread Luo pipe and circle cap screw like this.

Preferably, the length of internal thread Luo pipe is complementary with the width of U type connector, like this user only need screw and Luo managed to closely cooperate get final product, the length of riffled tube can be guaranteed the smooth and easy of rotational fixation, need not to debug repeatedly.

The weight bench of the utility model, the internal thread Luo pipe of the width coupling of employing and type connector is guaranteed the shank arm of force and being connected of U type connector being in the suitable position of degree of tightness and freely rotating to reach smooth and easy; And reduced assembly difficulty, the round cap design at screw and screwed pipe two ends can the person of avoiding the use of receive unexpected the scuffing.The design of the meticulous uniqueness at details place has demonstrated fully the intimate concern with humanization to the user, and taking care property is more paid close attention to user's mental impression.

Fig. 2 is the utility model suit bolt arrangement sketch map.

The specific embodiment

Be elaborated below in conjunction with the structure of accompanying drawing to the utility model.

The weight bench of the utility model comprises rear support stand, service creeper device and Calf structure.As depicted in figs. 1 and 2; Described Calf structure comprise the preceding upright beam 11 that is fixedly installed on the seat beam end, with described before upright beam 11 be fixedly connected on lower margin 1 before the U-shaped of its bottom; Upright beam 11 tops have been formed extended at both sides U-shaped connector 2 forward before described; At the hinged arm of force 12 that is provided with bending shape of the open side front end of described connector 2; Comprise that at the described arm of force 12 end is fixedly connected and the perpendicular transversal force arm 121 and the perpendicular arm of force 122; The perpendicular arm of force 122 vertically extends to be provided with bearing tube 13 forward near its bottom, carries out the Calf muscle training on it so that weight stack is provided with, and is provided with butterfly arm 10 in transversal force arm 121 end upper fixed dearly.Upright both sides, beam 11 top are provided with foam 14 respectively symmetrically before the both sides, outer end of the described arm of force 12 transversal force arms and the perpendicular arm of force reach.

The hinged employing suit bolt 20 of the described arm of force 12 and U-shaped connector 2, described suit bolt 20 comprise round cap internal thread Luo pipe 21 and the round cap screw 22 that matches.The round cap center of described round cap internal thread Luo pipe 21 and circle cap screw 22 is formed with the interior hexagonal screw of standard respectively.

Wherein, described round cap internal thread Luo length of tube can be confirmed according to the width of the U type connector on preceding Li Liang top, guarantee the shank arm of force and being connected of U type connector being in the suitable position of degree of tightness and freely rotating to reach smooth and easy; The round cap design at screw and screwed pipe two ends can the person of avoiding the use of receive unexpected the scuffing.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
