Technical Field

[0001] The utility model relates to the technical field of detonators, and particularly relates to a handheld wireless detonator with an anti-misoperation structure. Background Technique

[0002] A remote control detonator is a detonating device that controls the explosion of a charge at a certain distance through radio waves, sound waves or light beams. It usually consists of a transmitting mechanism and a receiving mechanism, and can accurately detonate multiple charges simultaneously or detonate the charges one by one. For some existing obstacle-breaking remote control detonators, there are certain inconveniences during use, which are not conducive to locking the control keys and are prone to misoperation, bringing potential safety hazards and great losses.

[0003] In order to solve the above problems, a patent document with the publication number "" discloses an obstacle-breaking remote control detonator, including a remote control detonator main body. A control key is movably connected to the front end of the remote control detonator main body. A fixing hole is penetrated through the inner end of the control key. A stop pin is embedded and installed at the inner end of the fixing hole. The tail end of the stop pin is fixedly connected with a slider. The outer end of the slider is movably connected with a first spring. The outer end of the first spring is wrapped with a chute, and the outer end of the chute is wrapped with a fixing block. It is convenient to lock the control key to prevent misoperation.

[0004] In the above-mentioned prior art, although the control key can be locked by the stop pin, when the external force applied is too large, the stop pin is easily deformed, thus losing the limiting function, and the limiting effect is not reliable enough. Therefore, a handheld wireless detonator with an anti-misoperation structure is needed. Content of the Utility Model

[0006] To achieve the above purpose, this application provides the following technical solution: A handheld wireless detonator with an anti-misoperation structure includes a detonator main body. An installation groove is arranged on the surface of the detonator main body. A detonating button is movably installed in the installation groove. A movable trigger piece is fixed at the lower end of the detonating button through a resisting column. The resisting column movably penetrates the bottom wall of the installation groove. The movable trigger piece is located in the inner cavity of the detonator main body. A fixed trigger piece corresponding to the position of the movable trigger piece is fixed in the inner cavity of the detonator main body. A detonation signal is generated when the movable trigger piece and the fixed trigger piece are in contact;

[0007] An elastic support member is installed in the installation groove. The bottom surface of the detonating button and the inner bottom wall of the installation groove are elastically connected through the elastic support member, and the elastic support member also functions as a torsion spring;

[0008] A positioning structure is also provided in the abutting column and the installation groove. When the positioning structures are adapted to each other, the abutting column can slide downward and drive the movable trigger piece to contact the fixed trigger piece. When the positioning structures are not adapted to each other, the distance that the abutting column slides downward is less than the distance between the movable trigger piece and the fixed trigger piece.

[0009] Preferably, a sliding hole for the abutting column to pass through movably is opened on the inner bottom wall of the installation groove, and the inner diameter of the sliding hole is equal to the diameter of the abutting column.

[0010] The positioning structure includes a positioning column and a positioning hole. The positioning column is fixed on the circumferential side of the abutting column, the positioning hole is opened on one side of the sliding hole, the positioning column and the positioning hole are adapted to each other, and the initial positions of the positioning hole and the positioning column are staggered.

[0011] Preferably, the positioning column is an irregular polygonal prism, the positioning hole is an irregular polygonal hole, and the cross-sectional shape and size of the positioning column are the same as those of the positioning hole.

[0012] Preferably, the elastic support member is a spring. The spring is sleeved on the abutting column movably. The upper end of the spring is fixed to the bottom surface of the detonating button, the lower end of the spring is fixed to the inner bottom wall of the installation groove, and metal columns are formed at both ends of the spring.

[0013] Preferably, a torsion piece is fixed on the upper surface of the detonating button, and the torsion piece is an S-shaped plate structure.

[0016] The initial positions of the second positioning point and the first positioning point form a 90° angle.

[0017] Preferably, when the positioning column is in the initial position, there is a gap between the lower end of the positioning column and the inner bottom wall of the installation groove, and the gap is less than the distance between the movable trigger piece and the fixed trigger piece.

[0018] In summary, the technical effects and advantages of the present utility model are as follows:

[0019] 1. In the present utility model, through the arrangement of the positioning structure and the elastic support member, when the detonating button is extruded by an external force due to accidental touch, and the detonating button drives the abutting column to slide, since the positioning structure is not adapted, at this time, the downward sliding distance of the abutting column is less than the distance between the movable trigger piece and the fixed trigger piece, so a detonation signal cannot be generated, playing a good role in preventing accidental touch, and this effect is stable and reliable, and will not cause uncontrollable deformation due to a large external force, and the support is more stable. When detonation is required, only by first rotating the detonating button to make the positioning structure adapted, at this time, the abutting column can slide downward and drive the movable trigger piece to contact the fixed trigger piece, so as to generate a detonation signal for detonation. Also, because the elastic support member has the functions of elastic support and torsion spring, it can absorb the extrusion force and torsion force of accidental touch, so that the detonating button is not easy to rotate when accidental touch occurs, thereby further avoiding the possibility of the positioning structure being adapted during accidental touch, thus improving the anti-accidental-touch effect of the handheld wireless detonator, and the operation during detonation is also more convenient.

[0020] 2. In the present utility model, by setting a gap between the lower end of the positioning column and the inner bottom wall of the installation groove, when the positioning column does not correspond to the positioning hole, the abutting column can also move downward a certain distance, which is beneficial for the spring to absorb the extrusion force generated by accidental touch, avoiding the situation that the abutting column cannot move downward, resulting in a hard collision between the detonating button and the accidentally touched object, and avoiding damage to the detonating button or other components, and extending the service life of the handheld wireless detonator to a certain extent.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] Embodiment: Refer to Figures 1-4 A hand-held wireless initiator with an anti-misoperation structure as shown, including an initiator body 1. An installation groove 11 is provided on the surface of the initiator body 1. An initiation button 2 is movably installed in the installation groove 11. A movable trigger piece 4 is fixed to the lower end of the initiation button 2 through a resistance column 3. The resistance column 3 movably penetrates the bottom wall of the installation groove 11. The movable trigger piece 4 is located in the inner cavity of the initiator body 1. A fixed trigger piece 5 corresponding to the position of the movable trigger piece 4 is fixed in the inner cavity of the initiator body 1. When the movable trigger piece 4 and the fixed trigger piece 5 are in contact, a detonation signal is generated;

[0029] An elastic support member is installed in the installation groove 11. The bottom surface of the initiation button 2 and the inner bottom wall of the installation groove 11 are elastically connected through the elastic support member. The elastic support member also functions as a torsion spring;

[0030] A positioning structure is also provided between the resistance column 3 and the installation groove 11. Based on the above structure, combined with the attached Figures 2-4 It can be seen that when the initiation button 2 is extruded by an external force of misoperation, when the initiation button 2 drives the resistance column 3 to slide, due to the inadaptability of the positioning structure, at this time, the downward sliding distance of the resistance column 3 is less than the distance between the movable trigger piece 4 and the fixed trigger piece 5. Therefore, a detonation signal cannot be generated, playing a good role in preventing misoperation, and this effect is stable and reliable, and will not produce uncontrollable deformation due to a large external force, and the support is more stable. When detonation is required, only by rotating the initiation button 2 first to make the positioning structure adaptable, at this time, the resistance column 3 can slide downward and drive the movable trigger piece 4 to contact the fixed trigger piece 5, so as to generate a detonation signal for detonation. Also, because the elastic support member has the functions of elastic support and torsion spring, it can absorb the extrusion force and torsional force of misoperation, so that the initiation button 2 is not easy to rotate when misoperation occurs, thereby further avoiding the possibility of the positioning structure being adaptable during misoperation, thereby improving the anti-misoperation effect of the hand-held wireless initiator, and the operation during initiation is also more convenient.

[0031] Furthermore, a sliding hole 12 for the abutting post 3 to movably penetrate through is formed in the inner bottom wall of the installation groove 11, and the inner diameter of the sliding hole 12 is equal to the diameter of the abutting post 3;

[0032] The positioning structure includes a positioning post 7 and a positioning hole 13. The positioning post 7 is fixed on the circumferential side of the abutting post 3, the positioning hole 13 is formed on one side of the sliding hole 12, the positioning post 7 and the positioning hole 13 are adapted to each other, and the initial positions of the positioning hole 13 and the positioning post 7 are staggered;

[0033] The positioning post 7 is an irregular polygonal prism, the positioning hole 13 is an irregular polygonal hole, and the cross-sectional shape and size of the positioning post 7 are both consistent with the cross-sectional shape and size of the positioning hole 13.

[0034] Through the arrangement of the positioning post 7 and the positioning hole 13, the abutting post 3 can drive the movable trigger piece 4 to contact the fixed trigger piece 5 only when the positions of the positioning post 7 and the positioning hole 13 correspond, providing good and stable anti-misoperation performance. And setting the positioning post 7 as an irregular polygonal prism can improve the alignment accuracy of the positioning post 7 and the positioning hole 13, thereby further increasing the difficulty of the corresponding positions between the two, and further improving the anti-misoperation performance and enhancing the safety.

[0035] Furthermore, the elastic support member is a spring 6. The spring 6 is movably sleeved on the abutting post 3. The upper end of the spring 6 is fixed to the bottom surface of the detonating button 2, and the lower end of the spring 6 is fixed to the inner bottom wall of the installation groove 11. Metal columns are formed at both ends of the spring 6. The spring 6 can not only provide elastic support for the detonating button 2 to help the detonating button 2 generate a reverse acting force when being misoperated, but also play the role of a torsion spring to help the detonating button 2 generate a reverse acting force when being misoperated by circumferential rotation, and help the detonating button 2 to quickly reset.

[0036] In order to facilitate the rotation and pressing of the detonating button 2 during detonation, a torsion piece 9 is fixed on the upper surface of the detonating button 2. The torsion piece 9 is an S-shaped plate structure. When detonation is required, the detonating button 2 can be rotated by rotating the torsion piece 9. When the detonating button 2 is rotated to a predetermined position, then press the detonating button 2, so as to facilitate the detonation operation, avoid slipping during the process of rotating and pressing the detonating button due to the reverse acting force of the spring 6, and the operation is more stable and convenient.

[0037] Furthermore, a second positioning point 8 is formed at the edge of the upper surface of the detonating button 2. The second positioning point 8 is triangular and one of its angles points to the side away from the axis of the detonating button 2. The second positioning point 8 corresponds to the position of the positioning post 7;

[0038] A first positioning point 14 is formed on the surface of the detonator body 1. The first positioning point 14 is also triangular and one of its angles points to the axis of the detonating button 2. The first positioning point 14 corresponds to the position of the positioning hole 13;

[0039] The initial position of the second positioning point 8 forms a 90° angle with the first positioning point 14;

[0040] Through the settings of the second positioning point 8 and the first positioning point 14, it is beneficial for the user to observe whether the positioning post 7 corresponds to the positioning hole 13, so that it is convenient for the user to rotate the positioning post 7 to the position corresponding to the positioning hole 13 when rotating the detonation button 2, facilitating the detonation operation.

[0041] Furthermore, when the positioning post 7 is in the initial position, there is a gap between the lower end of the positioning post 7 and the inner bottom wall of the installation groove 11, and the gap is smaller than the distance between the movable trigger piece 4 and the fixed trigger piece 5. In this way, when the positioning post 7 does not correspond to the positioning hole 13, the abutting post 3 can also move downward a certain distance, which is beneficial for the spring 6 to absorb the extrusion force generated by accidental touch, avoiding the situation where the abutting post 3 cannot move downward, resulting in a hard collision between the detonation button 2 and the accidentally touched object, and avoiding damage to the detonation button 2 or other components. To a certain extent, the service life of this handheld wireless detonator is extended.

[0042] The working principle of the present utility model: During daily use, when the detonation button 2 is extruded by an external force of accidental touch and the detonation button 2 drives the abutting post 3 to slide, due to the staggered positions of the positioning post 7 and the positioning hole 13, the distance that the abutting post 3 slides downward at this time is less than the distance between the movable trigger piece 4 and the fixed trigger piece 5. Therefore, no detonation signal can be generated, playing a good role in preventing accidental touch, and this effect is stable and reliable, and will not produce uncontrollable deformation due to a large external force, with more stable support. When detonation is required, only by rotating the detonation button 2 first to make the positioning post 7 and the positioning hole 13 correspond, can the abutting post 3 slide downward at this time and drive the movable trigger piece 4 to contact the fixed trigger piece 5, thereby generating a detonation signal for detonation. Also, because the spring 6 has an elastic support and a torsion spring effect, it can absorb the extrusion force and the torsional force of accidental touch, making the detonation button 2 not easy to rotate when accidental touch occurs, thereby further avoiding the possibility that the positioning post 7 and the positioning hole 13 correspond during accidental touch, thus improving the anti-accidental touch effect of this handheld wireless detonator, and the operation during detonation is also more convenient.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
