Description
Technical field
The utility model relates to body-building apparatus, and more particularly, the utility model is a kind of servicing unit that is used for sit-up exercise.
Background technology
Along with social development and growth in the living standard, increasing people pays close attention to the health of health and pursues the vigorous and graceful bodily form.Undoubtedly, sit-ups are exercising waies of a kind of simple and easy to do, definite effect.But when just beginning to take exercise, especially for the people of abdominal muscle strength deficiency, oneself often can't finish the action of a standard.Both feet are sticking up of free master not, and train on is had a greatly reduced quality, and enthusiasm also is affected, if temper and be subjected to the restriction of time and funds to the gymnasium.For a long time, people all thirst in the heart having one can auxiliary do-it-yourself sit-ups in bed device.Regrettably, do not find the report of Related product up to now as yet.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of servicing unit of sit-ups is provided.This device can help people's incremental performing physical exercise in bed.
The purpose of this utility model is achieved by following technical proposals.
The utility model provides a kind of servicing unit of sit-ups, and this device is formed by pressing plate, connecting rod, T type connecting rod, sponge, straight pin, contiguous block with spring-supported alignment pin.Two contiguous blocks that are equipped with circular hole of welding insert straight pin in the described circular hole on the pressing plate, and pressing plate and connecting rod are interfixed; The inner hollow of connecting rod, the longitudinal rod of T type connecting rod inserts connecting rod inside.Be connected with spring-supported alignment pin between connecting rod and the T type connecting rod.Sponge wrapping is on the transverse bar of T type connecting rod.
The identical circular hole of equally distributed diameter is arranged in processing one on the connecting rod, is used to locate the height and position of T type connecting rod.Oblique angle of pressured plate one side polishing, connecting rod bottom so that connecting rod is the axle center rotation with the straight pin, increases the stressed reasonability of connecting rod in the use.
Using method of the present utility model and operation principle:
Insert under the mattress pressing plate fixing, depress alignment pin, move and adjust T type connecting rod to correct position, unclamp alignment pin and fix T type connecting rod, both feet are stretched into the following of sponge and catch on the transverse bar of T type connecting rod, rely on mattress and user's self weight to fix pressing plate, can begin to do sit-up movement.When giving up doing exercise, be the axle center rotation with the straight pin,, be convenient to collection described folding device by connecting rod.
Compared with prior art, the utlity model has following outstanding advantage:
1. simple and reasonable, described device has utilized mattress and user's self weight to fix the pressing plate .2. easy disassembling of sit-ups dexterously, do not take up space, the time spent can not depressed connecting rod, be contracted to bedside, collect after also detachable folding to wardrobe or the drawer .3. take exercise convenient, at any time all can carry out, evening hora somni(hs), before getting up morning, work tired when thinking of having a rest, or on the date that it's raining and blowing hard, home-confined, pull out this device easily, just can perform physical exercise .4. under the help of servicing unit, temper free and relaxed action norm, adhere to easily, if room, respond well .5. hotel has described device, will greatly facilitate the passenger and take exercises, promote the competitiveness in hotel. in sum, the practicality of this product is extremely strong, and market application foreground is wide.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail, but this is not the qualification to the utility model protection domain.
Embodiment
The servicing unit of sit-ups is formed by pressing plate 1, connecting rod 2, T type connecting rod 3, sponge 4, straight pin 5, contiguous block 6 with spring-supported alignment pin 7.Two contiguous blocks 6 that are equipped with circular hole of welding on the pressing plate 1 insert straight pin 5 in the described circular hole, and pressing plate 1 and connecting rod 2 are interfixed; The inner hollow of connecting rod 2, the longitudinal rod of T type connecting rod 3 inserts connecting rod 2 inside.Be connected with spring-supported alignment pin 7 between connecting rod 2 and the T type connecting rod 3.Sponge 4 is wrapped on the transverse bar of T type connecting rod 3.
The identical circular hole of equally distributed diameter is arranged in processing one on the connecting rod 2, is used to locate the height and position of T type connecting rod 3.Oblique angle of pressured plate 1 one sides polishing, connecting rod 2 bottoms, purpose are that to make connecting rod 2 be the axle center rotation with straight pin 5, increase the stressed reasonability of connecting rod in the use 2, and this folding device can be convenient to collection and be taken care of.The length of connecting rod 2 is decided according to the thickness of the mattress that uses in the daily life, and is slightly shorter than the gauge of mattress.
T type connecting rod 3 is fixedly formed through welding by two orthogonal connecting rods, and effect is the pin that catches on the user.The inner hollow of the longitudinal rod of T type connecting rod 3, circular hole of bottom processing, diameter is identical with circular hole on the connecting rod 2, and alignment pin 7 of being pushed down by spring 8 of the installation hole in is depressed the height of the alignment pin 7 removable T of adjustment type connecting rods 3, reaches comfortable use location.
Sponge 4 is wrapped on the transverse bar of T type connecting rod 3, and effect is in the transverse bar of user's pin contact T type connecting rod 3, buffering and reduce user's arch face and pressure, the frictional force between the T type connecting rod 3, allow user's energy comfortable do sit-ups.
