Technical Field

The invention relates to the technical field of ribbon manufacturing, in particular to a ribbon with a self-locking structure.

Background

A cable tie is a type of band used for bundling articles, which is widely used in various industries. Common ties include plastic ties and metal ties, depending on the material; because plastics are poor in heat resistance, corrosion resistance and ultraviolet light resistance, the application range of the plastic ribbon is limited, and the metal ribbon has a wider application range than the plastic ribbon.

The binding belt can meet the binding requirements in a general environment, but in some cases, the requirement on pulling and separating is high or the use environment is special (such as a vibration environment), the binding belt has higher requirements. In order to ensure the binding firmness of the binding tape, the binding and locking binding tape is generally subjected to a pull-out force test and a vibration pull-out force test (i.e., the pull-out force test is performed again in a simulated vibration environment). In order to improve the locking force of the ribbon, a steel ball is arranged in a lock catch, for example, the steel ball 200720195240.7 and 201320720451.3 adopt the structure, and the extrusion force of the steel ball on the ribbon body is improved through the matching of the steel ball and the inner inclined surface of the lock catch, so that the locking force of the ribbon is improved. The structure can improve the locking force of the ribbon and can pass the pull-off test of the ribbon; however, because the steel ball is not fixed in the lock catch, when the vibration tension test is carried out, the steel ball is easy to slide, so that the locking force is insufficient, and the steel ball cannot pass the vibration tension test.

As another patent 201720476803.3, the fixing groove is formed on the belt body, and the fixing is realized by inserting and matching the extrusion rod and the fixing groove; in addition like patent 201720489809.4, through setting up the lock door, be connected with the metal strip on the lock door, set up the circular port on the area body, it is fixed to join in marriage the realization through inserting of metal strip and circular port. The above-mentioned 2 patent locking structure essentials are similar, utilize the inserted bar (inserted bar) to join in marriage with inserting of fixed slot (fixed orifices) and realize fixedly, but because the setting of fixed slot (fixed orifices) is the spaced, consequently can't realize the locking of optional position, and this can cause very big trouble in the use of ribbon, can lead to the unable effective locking of ribbon.

The invention aims to solve the technical problem of the prior art and provides a ribbon with a self-locking structure, which is simple in structure, convenient to use and capable of forming self-locking at any position.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides a ribbon with auto-lock structure, including strap and fixed head, the one end of strap be the stiff end, fixed mutually with the fixed head, its other end is for penetrating the end, the fixed head on be provided with the mouth of penetrating that runs through mutually and wear the export, fixed head internal fixation have a locking piece, the locking piece including fixed part and locking portion, fixed part and locking portion between be formed with deformation portion, locking portion and strap penetrate the end directional contained angle that penetrates the mouth direction and be the acute angle.

The optimized technical measures further comprise:

the included angle ranges from 70 degrees to α degrees which is less than 90 degrees.

The deformation part is an elastic part which enables the locking part to move elastically towards the direction of the penetration opening.

The fixing part is positioned on the side of the penetration port, and the locking part is positioned on the side of the penetration port.

The fixing part is positioned on the side of the penetration port, and the locking part is positioned on the side of the penetration port.

The two ends of the fixing part are respectively connected with a locking part.

The fixed head on punching press form the fixed slot, the middle part of the fixed part of lock piece seted up the socket, the both sides of this socket are provided with a pair of fixed oblique piece, the lock piece be fixed in the fixed head through the card cooperation of fixed oblique piece and fixed slot.

The fixing head is provided with an opening at one end, the fixing head is punched to form a fixing block, a clamping groove is formed in the fixing block, a fixing part of the locking piece is provided with an insertion hole and an inclined clamping piece, and the locking piece is fixed in the fixing head through the inclined clamping piece and the clamping groove in a clamping fit mode.

The locking part is vertically provided with a reinforcing rib along the locking part.

The two sides of the locking part are bent to form reinforcing edges.

The binding belt with the self-locking structure is simple in structure, the locking piece is fixed in the fixing head, the locking piece comprises a fixing part, a deformation part and a locking part, and an included angle formed by the locking part and the penetrating end of the metal belt in the direction pointing to the penetrating port is an acute angle; when the penetrating end of the metal strip penetrates, the deformation part deforms, the locking part deflects towards the penetrating port side, the penetrating end can penetrate smoothly, and when the metal strip is pulled out reversely, the penetrating end surface abuts against the end face of the locking part to form self-locking. The ribbon has low manufacturing cost, can form self-locking at any position and is very convenient to use.
