Abstract
The utility model discloses a kind of dumbbell bar dop, described dumbbell bar collet body is divided into two parts by shape: the first cylinder and the second cylinder, described second cylindrical external diameter is greater than the first cylinder, the hollow structure that two cylinder indoor designs have internal diameter consistent, and hollow structure inner surface has inner threaded surface to be engaged with the screw thread on dumbbell bar is suitable, described first cylindrical lateral layout has a screwed hole and the nut suitable with it.The thread pore structure that the utility model designs in the side of dumbbell bar dop, after the utility model being rotated on dumbbell bar install, the effect of reinforcing this dumbbell bar dop can be reached again by inwardly rotating the nut suitable with this screwed hole, make this dumbbell bar dop more firm by this ruggedized construction, not easily come off or the phenomenon of slide fastener, avoid dangerous generation, ensure that the safety of user.
Description
Technical field
The utility model relates to field of exercise equipment, specifically, relates to a kind of dumbbell bar dop.
Background technology
Dumbbell is a kind of simple equipment for strengthening muscle strength training.Its purposes is for exercise for power, and muscle composite move is trained.Because of the patient that motor paralysis, pain, long-term immobilization etc. cause muscular strength low, hand-held dumbbell, can utilize the weight of kinetic dumbbell to carry out resistive drag force active movement, training muscular strength.Dumbbell can train single muscle; As gained in weight, then needing the coordination of multiple muscle, also can be used as the training of a kind of muscle composite move.
As a kind of auxiliary appliance of weight lifting and exercise, dumbbell have a fixed weight with two kinds of adjustable weight, dumbbell structure is made up of dumbbell bar and dumbbell plate, dumbbell plate can increase according to the needs of people's exercise or reduce, but dumbbell plate is in use easy to landing, injure user by a crashing object, therefore dumbbell bar dop just becomes one of requisite structure in dumbbell, dumbbell plate is pinned in the effect of dumbbell bar dop, the slip of restriction dumbbell plate, ensures that it can not cause personal injury to user.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of dumbbell bar dop, and its purposes is by fixing locked dumbbell plate on dumbbell bar, prevents dumbbell plate landing, injures practitioner by a crashing object.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of dumbbell bar dop, it is characterized in that, described dumbbell bar collet body is divided into two parts by shape: the first cylinder and the second cylinder, described second cylindrical external diameter is greater than the first cylinder, the hollow structure that two cylinder indoor designs have internal diameter consistent, and hollow structure inner surface has inner threaded surface to be engaged with the screw thread on dumbbell bar is suitable, described first cylindrical lateral layout has a screwed hole and the nut suitable with it, and described screwed hole is got through in the first cylindrical hollow structure.
Preferably, described first cylindrical entire length is greater than the second cylinder.
Owing to have employed technique scheme, the utility model devises a thread pore structure in the side of dumbbell bar dop, screwed hole has directly been got through in the first cylindrical hollow structure, such dumbbell bar loaded dumbbell plate and rotate install the utility model after, can again by reaching the effect of reinforcing this dumbbell bar dop to rotating nut on the cylindrical side of this dumbbell bar dop first, this dumbbell bar dop can be made more firm by this structure, not easily come off or the phenomenon of slide fastener, avoid dangerous generation, ensure that the safety of user.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, 2, a kind of dumbbell bar dop, described dumbbell bar collet body is divided into two parts by shape: the first cylinder 1 and the second cylinder 2, the external diameter of described second cylinder 2 is greater than the first cylinder 1, the hollow structure that two cylinder indoor designs have internal diameter consistent, and hollow structure inner surface has inner threaded surface 3 to be engaged with the screw thread on dumbbell bar 6 is suitable, the lateral layout of described first cylinder 1 has a screwed hole 4 and the nut 5 suitable with it, and described screwed hole 4 is got through in the first cylinder 1 hollow structure.
The hollow structure inner surface of the utility model first cylinder 1 and the second cylinder 2 indoor design has inner threaded surface 3 to be engaged with the screw thread on dumbbell bar 6 is suitable, rotate this dumbbell bar dop on dumbbell bar 6, reach effect fixing for the first time, then nut 5 is rotated in the screwed hole 4 of side of the first cylinder 1, until touch the dumbbell bar 6 in hollow structure, screw up with a wrench again fixing, reach the effect that second time is fixing.
The utility model is by design twice screw-tightened structure, make to which give dual fixing guarantee, ensure that the reliable location of dumbbell plate and dumbbell bar dop, it also avoid dumbbell plate and dumbbell bar dop comes off from dumbbell bar, the generation of landing phenomenon, improve the safety coefficient of product, ensure that the personal safety of user.
In order to further prioritization scheme, structure of the present utility model is that the external diameter of the second cylinder 2 is greater than the first cylinder 1, the entire length of the first cylinder 1 is greater than the second cylinder 2, and the object of this structural design can hold this dumbbell bar dop for the convenience of the users, makes its not easily landing.
The utility model is not limited to above-mentioned preferred embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or akin technical scheme with the utility model, all belongs to protection domain of the present utility model.
Claims (2)
