Abstract
The utility model provides an adjustable tightening barbell lock. The utility model is characterized in that the adjustable screwing barbell clock comprises a tightening part A, a locking hoop, a tightening part B and a locking cover; the outer round of the locking hoop appears as a cone, and a diameter-shrinking groove is arranged on the locking hoop which is positioned into the tightening part B. And one face of the cone of the locking hoop matches with the inner cone-hole of the tightening piece B. One face of the tightening part A touches one face of the locking hoop and the tightening part A is screwed with the tightening part B. When the diameter changes greatly on size in the tolerance, the lock can be adjustably tightened. The overall sealed structure of the utility model has the advantages of that the lock cannot be taken down; disorder can be avoided; loss and damage can be reduced; the use is convenient, etc.
Description
Technical field
The utility model belongs to sports equipment, uses the screwing type the regulated barbell tapered end of locking barbell disc on the bar specifically in the weight lifting sports.
Background technology
At present, the barbell that uses in the weight lifting sports is in order to prevent in the use barbell disc mobile landing from the bar.All be to use special locking device all the time, form by being contained on the outer bar head of barbell disc threaded plum blossom tapered end, spring etc. at bar.They are the uncontrollable defective cun in the aperture all, a kind of bar can only use specification tapered end of the same race, when if the diameter dimension fluctuation range (margin of tolerance) of bar is bigger, the tapered end damage in use takes place or loses in the user so, like this, just be difficult to find suitable tapered end and bar to be complementary.
Summary of the invention
The utility model purpose is the deficiency that is latched at existing barbell, overcomes the restriction that a kind of bar can only specification tapered end of the same race, and provides simple in structure, entanglement easily takes place, the screwing type regulated barbell tapered end easy to use.
The technical solution of the utility model is achieved in that
A kind of screwing type barbell tapered end of regulating is characterized in: comprise screwing part A, locking strap, screwing part B, tightening cover; The cylindrical of locking strap is a cone, has the undergauge groove on the locking strap; Locking strap is put into and screws in the part B, and the one side cone of locking strap is matched with the inner cone body opening that screws part B; Screwing part A has face of a face and locking strap to contact, and screws part A and screws part B with being threaded.
Above-describedly screw part A a face is arranged is inner conical surface, another face of locking strap is a cone also, screws part A inner conical surface and matches with the one side cone of locking strap.
The above-described part A that screws is provided with to take and colludes, and tightening cover is provided with corresponding boss hasp, screws part A and is enclosed within the tightening cover pressing that screws on the part B, screws taking of part A and colludes with corresponding boss hasp on the tightening cover and be connected.
The screwing type the regulated barbell tapered end that the utility model provides is compared with prior art: when the diameter dimension of bar when the margin of tolerance changes greatly, its lock can be regulated and screw, its full-closed structure, have non-dismountable, be difficult for taking place entanglement, advantages such as minimizing damages and loses, and is easy to use.
Description of drawings
Fig. 1 can regulate the structural representation of screwing type barbell plastics tapered end for the bicone locking strap;
Fig. 2 can regulate the structural representation of screwing type barbell plastics tapered end for single taper locks lock ring.
The specific embodiment
Shown in Figure 1, for the bicone locking strap can be regulated screwing type barbell tapered end.It comprises screw part A1, locking strap 2, screw part B3, tightening cover 4; The cylindrical of locking strap is a bicone 201, has undergauge groove 202 on it; Locking strap is put into and screws part B, and the one side cone of locking strap is matched with the inner cone body opening that screws part B; Screwing part A inner conical surface matches with the another side cone of locking strap; Screw part A and screw part B with being threaded; Screw part A and be provided with to take and collude, tightening cover is provided with corresponding boss hasp, screws part A and is enclosed within the tightening cover pressing that screws on the part B, screws taking of part A and colludes with corresponding boss hasp on the tightening cover and be connected.Screw part A and screw part B and also can not establish hasp with being enclosed within, but adopt gluing mode to connect.
Shown in Figure 2, for single taper locks lock ring can be regulated screwing type barbell tapered end.Above-mentioned screw part A1 a face is arranged is inner face, and be that the end face of the locking strap other end of cone matches with an end.
Above-mentioned bicone or single taper locks lock ring can be regulated screwing type barbell tapered end, and it screws part A1, locking strap 2 and screws three holes on the part B3 for concentric.Bar is through in the hole of locking strap (2), so just consists of a non-removable plastics barbell tapered end of regulating.
Above-mentioned each part of barbell tapered end can be made of plastic, also can make with metal or light-weight metal, as brass, aluminium alloy, magnesium alloy or the like.
When the utility model can be regulated the use of screwing type barbell tapered end, the indication " UN-LOCK " " LOCK " of part B according to its end face will be screwed, screw or unclamp according to the indicated direction of arrow, the aperture of locking strap diminishes under the effect of the part B conical surface or becomes big with screwing part A and screw at its conical surface so.So just realized the function of regulating, and be that tapered end can be locked on the bar of different diameters (φ 24mm～φ 26mm) securely.
