Description

Technical Field

[0001] This utility model relates to the field of winding device technology, and more specifically, to a winding device with a detonator and wire clip storage structure. Background Technology

[0002] After the electronic detonator is manufactured, a winding device is needed to coil and store the connecting leads in the electronic detonator. Currently, common winding devices on the market only have the function of storing the connecting leads between the detonator and the wire clamp, but they cannot store the detonator and the wire clamp. As a result, when transporting electronic detonators, the detonators are prone to colliding with other objects due to shaking, which may cause safety risks. In addition, the connecting leads are prone to becoming loose and knotted on the winding device, which affects the wire release efficiency during subsequent use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a winding device with a detonator and wire clip storage structure, which can effectively avoid the safety hazards caused by the detonator being hit, and can effectively prevent the connecting wires from becoming loose or knotted.

[0004] This utility model provides a winding device with a detonator and wire clamp storage structure, including a winding disc, a ring-shaped winding area formed in the middle of the winding disc in the axial direction, a cavity provided in the middle of one end of the winding disc for storing the detonator and wire clamp; a ring-shaped wire groove provided on the outer side of the cavity in the circumferential direction, a plurality of notches distributed circumferentially at intervals at one end of the winding disc for connecting the cavity and the wire groove, a plurality of opening slots distributed circumferentially at intervals at the inner end of the wire groove for connecting the wire groove and the winding area; the connecting wires of the detonator and the wire clamp are wound in the winding area, and the connecting wires are embedded in the wire groove, some notches and some opening slots.

[0005] After the connecting lead wire is coiled and stored, the detonator and wire clamp can be stored in the cavity, which can effectively avoid the safety hazards caused by the detonator being hit. The connecting lead wire located at the end of the detonator and wire clamp can be embedded in the opening groove, wire groove and notch, which can effectively prevent the connecting lead wire from becoming loose or knotted, so as to facilitate the release of the connecting lead wire during subsequent use.

[0006] In one possible implementation, a snap-fit ​​structure is provided at the inner end of the cavity, and the detonator is snapped into the cavity through the snap-fit ​​structure; by adopting this structure, the detonator can be reliably snapped into the cavity under the action of the snap-fit ​​structure, that is, the detonator can be reliably stored in the cavity.

[0007] In one possible implementation, the locking structure includes two sets of hook groups respectively disposed on both sides of the detonator in the axial direction. Each set of hook groups includes several hooks spaced apart along the axial direction of the detonator. Each hook is connected to the inner end of the cavity. The two sides of the detonator in the axial direction respectively engage with the hooks on the corresponding sides. With this structure, when the detonator is placed between the two sets of hook groups, the detonator can be locked between the two sets of hook groups, that is, the two sides of the detonator in the axial direction can engage with the hooks on the corresponding sides, thereby enabling the detonator to be reliably locked in the cavity.

[0008] In one possible implementation, a plug-in structure is provided at the inner end of the cavity, and the wire clip is inserted tightly into the plug-in structure. With this structure, the wire clip can be reliably plugged into the cavity under the action of the plug-in structure, that is, the wire clip can be reliably stored in the cavity.

[0009] In one possible implementation, the plug-in structure includes two protrusions disposed on the inner end of the cavity, the two protrusions being arranged opposite each other, and slots being formed on the inner sidewalls of both protrusions. Plug-in ribs are provided on both outer walls of the wire clip, and each plug-in rib is inserted into the corresponding slot. With this structure, after the wire clip is placed in the cavity and the plug-in ribs on both outer walls of the wire clip are engaged and inserted into the corresponding slots, the wire clip can be reliably stored in the cavity.

[0010] In one possible implementation, the opening end of each slot is located on the peripheral wall of the winding spool, and the opening end of each slot forms a constriction. By adopting this structure, after the connecting wire is inserted into the slot through the constriction, it can effectively prevent the connecting wire from freely coming out of the slot, thereby improving the reliability of the connecting wire after it is inserted into the slot.

[0011] In one possible implementation, both sides of each notch are formed with arc surfaces; by adopting this structure, after the connecting line is embedded in the notch, the arc surfaces can prevent the connecting line from being cut by the two side walls of the notch, that is, the connecting line can be prevented from being damaged.
