Detailed implementation manners

[0031] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 to 14 shown, a fixing bracket for ship electrical fittings includes a support base 3, and further includes: Two groups of special-shaped mechanisms 2, which are symmetrically arranged at both ends of the upper surface of the support base 3. Both groups of special-shaped mechanisms 2 are composed of multiple groups of fixing plates 202 and fastening components 203. Adjacent two groups of fixing plates 202 are rotatably arranged with each other, and multiple groups of fixing plates 202 are fixedly arranged with each other through the fastening components 203; Through the design that multiple groups of fixing plates 202 are fixedly arranged with each other through the fastening components 203, after multiple groups of fixing plates 202 rotate with each other and all fit on the irregular ship electrical fittings, the position can be quickly fixed through the fastening components 203, without the need for the traditional fixing method of using multiple bolts to be installed at different positions. Therefore, through the design of the fastening components 203 and multiple groups of fixing plates 202, the irregular ship electrical fittings can be quickly positioned and fixed.

[0033] A pre-positioning mechanism 1, which is composed of multiple groups of pre-fixing components 106 and a triggering component. The triggering component is arranged in the middle of the upper surface of the support base 3. Both groups of special-shaped mechanisms 2 are arranged to approach or separate from each other through the triggering component. An installation area is formed between the two groups of special-shaped mechanisms 2, and multiple groups of pre-fixing components 106 are arranged to approach each other through the triggering component.

[0034] As Figures 1 to 14 shown, due to the design that multiple groups of pre-fixing components 106 are spatially arranged with each other through the triggering component, the pre-fixing components 106 can first pre-position the ship electrical fittings, so that the ship electrical fittings will not shake significantly, thus facilitating the subsequent fixing of the ship electrical fittings by the special-shaped mechanism 2. Therefore, there is no need for manual intervention to stabilize the ship electrical fittings, further improving the practicability and convenience of the fixing bracket; Further, a second triggering plate 204 is arranged on the same side of multiple groups of fixing plates 202, and adjacent two groups of fixing plates 202 are rotatably arranged with each other through a second torsion spring 205; Specifically, as Figures 9 to 11 shown, convex blocks are arranged at both ends of the bottom of the fixing plate 202, a rotating groove for the convex blocks to rotate is opened at the top of the fixing plate 202, and the second torsion spring 205 is fixedly installed between the convex blocks and the rotating groove, so that adjacent two groups of fixing plates 202 can automatically rotate under the action of the second torsion spring 205.

[0035] Furthermore, extrusion blocks 206 are provided at both ends on one side of the second trigger plate 204. One end of the extrusion block 206 is inclined. A limiting plate 207 is elastically and slidably installed on the other side of the fixed plate 202. Sliding holes 5 are formed at both ends on the other side of the fixed plate 202, and the extrusion block 206 is slidably installed inside the sliding hole 5. A pressure-receiving hole is formed on one side of the limiting plate 207, and the pressure-receiving hole is arranged corresponding to one end of the extrusion block 206; A second limiting block 9 is fixedly installed at the lower end on the other side of the fixed plate 202, and the second limiting block 9 is arranged corresponding to the limiting plate 207; As Figures 1 to 14 shown, through the design of the extrusion block 206 and the pressure-receiving hole, when the lower fixed plate 202 flips close to the marine electrical fitting through the second torsion spring 205, the second trigger plate 204 is squeezed and slides along the direction of the sliding hole 5. The extrusion block 206 passes through the inside of the sliding hole 5 and squeezes the pressure-receiving hole. Relying on the inclined characteristic, the limiting plate 207 slides downward and away from the upper second limiting block 9. Therefore, the second limiting block 9 of the upper fixed plate 202 is released, so that the upper fixed plate 202 can flip and fit to the surface of the marine electrical fitting through the action of the second torsion spring 205, achieving the effect of automatic fitting and extrusion; Specifically, as Figures 1 to 14 shown, the second trigger plate 204 in the above includes a first special-shaped plate 2041. Second special-shaped plates 2042 are damping slidably installed at both ends on one side of the first special-shaped plate 2041, and third special-shaped plates 2043 are damping slidably installed on the same side of the two groups of second special-shaped plates 2042. The same side of the first special-shaped plate 2041, the second special-shaped plate 2042, and the third special-shaped plate 2043 is arc-shaped.

[0036] Through the design of damping sliding of the first special-shaped plate 2041, the second special-shaped plate 2042, and the third special-shaped plate 2043, and by simulating a special-shaped vise, when the fixed plate 202 drives the second trigger plate 204 to squeeze the surface of the marine electrical fitting, it can extend into the groove part on the outer surface of the marine electrical fitting, increasing the contact area, thereby further improving the stability of the irregular-type marine electrical fitting on the fixing bracket. Therefore, the applicability range and practicality of the fixing bracket are effectively improved.

[0037] Specifically, as Figures 1 to 14 shown, ceramic bearings 2044 are rotatably installed at both ends on the same side of multiple groups of third special-shaped plates 2043; By designing that ceramic bearings 2044 are rotatably installed at both ends of the same side of multiple groups of third special-shaped plates 2043, compared with the traditional method of extrusion fixation using a solid plane, it can avoid the friction generated when the fixture fits and clamps the ship electrical fitting from damaging the surface of the ship electrical fitting when the position of the ship electrical fitting is not centered; during the clamping process, the ceramic bearings 2044 rotate due to the friction during contact, which can avoid the above situation.

[0038] Moreover, by adopting the rotational contact of the ceramic bearings 2044, in any case, the special-shaped mechanism 2 can have the possibility of movement with the ship electrical fitting, avoiding the situation where when the special-shaped mechanism 2 is jammed due to mechanical dead points inside and cannot move, it violently clamps the ship electrical fitting and causes damage.

[0039] Furthermore, the fastening component 203 includes multiple groups of fastening sleeves 2031 and transmission components. The fastening sleeves 2031 are slidably installed at one end of the fixing plate 202, and the fastening sleeves 2031 are arranged close to the second torsion spring 205. The fastening sleeves 2031 are slidably arranged in the same direction through the transmission components; the transmission components include multiple groups of mounting shells 2039, and the mounting shells 2039 are fixedly installed at one end of the fixing plate 202. A bevel gear transmission mechanism 2035 is arranged inside the mounting shell 2039. One end of an adjacent group of bevel gear transmission mechanisms 2035 is drivingly connected to a telescopic rod 2037, and a universal rod structure 2038 is arranged between one end of another adjacent group of bevel gear transmission mechanisms 2035 and the telescopic rod 2037; The other end of the bevel gear transmission mechanism 2035 is drivingly connected to a fastening screw 2036. The fastening sleeve 2031 is threadedly sleeved on the outside of the fastening screw 2036. The fastening screw 2036 is rotatably connected to the mounting shell 2039. The fastening sleeve 2031 is used to fix the second torsion spring 205. A transmission rod 2034 is rotatably installed on the outside of one of the mounting shells 2039, and the transmission rod 2034 is drivingly connected to one of the bevel gear transmission mechanisms 2035; Exemplarily, the above-mentioned universal rod structure 2038 uses the existing mature universal rod mechanism technology. Therefore, no matter how the adjacent two groups of fixing plates 202 are flipped at any angle, the adjacent two groups of bevel gear transmission mechanisms 2035 can still be drivingly connected through the universal rod structure 2038 and the telescopic rod 2037, so as to ensure that only by controlling the rotation of one group of bevel gear transmission mechanisms 2035, all the fastening screws 2036 can be driven to rotate, enabling the fastening sleeves 2031 to squeeze the convex blocks, so that the adjacent two groups of fixing plates 202 are fixed at the same angle simultaneously, thereby further improving the convenience when the positions of multiple groups of fixing plates 202 are fixed.

[0040] Specifically, as Figures 1 to 14 shown, a fastening groove is opened on one side inside the rotation groove, and the fastening sleeve 2031 is slidably installed inside the fastening groove, and the fastening screw 2036 is rotatably installed inside the fastening groove; Specifically, Figures 1 to 14 As shown, an adjusting knob 2033 is slidably mounted on one end of the outer side of the transmission rod 2034, and the adjusting knob 2033 is located outside the mounting shell 2039. A fastening nut 2032 is threadedly connected to one end of the outer side of the transmission rod 2034, so that the adjusting knob 2033 is fixed to the mounting shell 2039 through the fastening nut 2032. The design of the adjusting knob 2033 can facilitate the staff to drive the transmission rod 2034 to rotate, and the fastening nut 2032 can be used to fix the adjusting knob 2033 to prevent the adjusting knob 2033 from being easily rotated by external collisions, causing the angles of the multiple sets of fixing plates 202 to loosen.

[0041] Furthermore, the trigger component includes a bearing plate 101, a groove is provided in the middle of the upper surface of the support seat 3, and the bearing plate 101 is elastically slidably installed inside the groove, both ends of the bearing plate 101 are connected to a transmission seat 105 through a gear set, the transmission seat 105 is slidably installed on the upper surface of the support seat 3, and the transmission seat 105 is movably connected to the fixing plate 202 located below; Specifically, Figures 1 to 14 As shown, an adjustment groove is opened on the upper surface of the transmission seat 105, and an adjustment screw 6 is rotatably installed inside the adjustment groove, a threaded block 7 is slidably installed inside the adjustment groove, and the threaded block 7 is threadedly sleeved on the outside of the adjustment screw 6, and the threaded block 7 is fixedly connected to the bottom of the fixed plate 202 located below.

[0042] By adjusting the design of the screw rod 6 and the threaded block 7, the initial positions of multiple sets of fixing plates 202 on the same side can be adjusted, so that the fixing bracket can select the best fitting fixing position according to the asymmetric ship electrical equipment, thereby further improving the practicality of the fixing bracket.

[0043] Specifically, the gear set mentioned above includes a first tooth plate 102 and a second tooth plate 103, lifting grooves are provided at both ends of the groove on both sides, a reset spring 4 is fixedly installed at the lower end of the lifting groove, and the first tooth plate 102 is elastically slidably installed in the lifting groove through the reset spring 4, sliding grooves communicating with the interior of the lifting groove are provided at both ends of the upper surface of the support seat 3, and a transmission seat 105 is slidably installed in the sliding groove, a transmission gear 104 is rotatably installed in the lifting groove, the first tooth plate 102 and the second tooth plate 103 are both meshed and connected with the transmission gear 104, and the transmission seat 105 is fixedly connected to the second tooth plate 103, and symmetrical avoidance grooves are provided at both ends of the carrier plate 101, and the avoidance grooves are arranged corresponding to the second tooth plate 103.

[0044] Through the design of the first tooth plate 102, the second tooth plate 103 and the transmission gear 104, when the ship's electrical equipment is placed on the upper surface of the load-bearing plate 101, the load-bearing plate 101 drives the first tooth plate 102 to descend, and drives the second tooth plate 103 to slide through the transmission gear 104, and controls multiple groups of fixing plates 202 to approach the ship's electrical equipment for wrapping and squeezing, thereby realizing rapid positioning and fixing of the ship's electrical equipment.

[0045] It should be noted that, through the design of the avoidance groove, firstly, the second tooth plate 103 can be prevented from colliding with the load-bearing plate 101, and secondly, the second tooth plate 103 can enter the avoidance groove to prevent collision with the ship's electrical equipment, resulting in the fixing plate 202 being unable to touch the ship's electrical equipment.

[0046] Further, both ends of both sides of the groove are provided with mounting grooves, the pre-fixed component 106 is located inside the mounting grooves, and the pre-fixed component 106 is fixedly connected to the transmission seat 105; the pre-fixed component 106 includes a spring movable rod 1061 and two sets of abutment plates 1062, the spring movable rod 1061 is fixedly connected to the transmission seat 105, and the spring movable rod 1061 is slidably installed inside the mounting grooves, and the two sets of abutment plates 1062 are symmetrically rotated and installed on the movable end of the spring movable rod 1061 through the first torsion spring 1063; like Figures 1 to 14 As shown, through the design of the spring movable rod 1061, the two groups of contact plates 1062 can touch the outer surface of the ship's electrical equipment first than the multiple groups of fixed plates 202, and the spring movable rod 1061 has the movable characteristics, so that when the fixed plate 202 moves, the two groups of contact plates 1062 can first squeeze the outer surface of the ship's electrical equipment, and the symmetrical arrangement of the spring movable rod 1061 can make the ship's electrical equipment more stable on the upper surface of the bearing plate 101 to avoid shaking, so that it is not necessary to manually intervene to stabilize the ship's electrical equipment, thereby further improving the convenience of using the fixing bracket; Specifically, Figures 1 to 14 As shown, two groups of support rods 1064 are symmetrically arranged at one end of the spring movable rod 1061, and placement grooves are opened on the opposite sides of the two groups of contact plates 1062. One end of the support rod 1064 is rotatably installed inside the placement groove, and a first limit block 8 is fixedly installed inside the placement groove. The two ends of the first torsion spring 1063 are respectively fixedly connected to the support rod 1064 and the inside of the placement groove.

[0047] Through the design of the first limit block 8, the contact plate 1062 automatically rotates under the action of the first torsion spring 1063. The limiting effect of the first limit block 8 allows the contact plate 1062 to only rotate ninety degrees in one direction, thereby preventing the contact plates 1062 from being attached to each other in a horizontal state.

[0048] Through the design of two sets of rotatable contact plates 1062, the two sets of contact plates 1062 initially remain perpendicular. When contacting the sunken area on the outer surface of the marine electrical fitting, the two sets of contact plates 1062 rotate in opposite directions, and through the elasticity of the first torsion spring 1063 and the spring movable rod 1061, the outer surface of the marine electrical fitting is always squeezed to prevent the marine electrical fitting from being squeezed. The two sets of contact plates 1062 can stably fit irregular or flat marine electrical fittings, further improving the stability when pre-positioning the marine electrical fittings.

[0049] The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
