DETAILED DESCRIPTION EMBODIMENT

[0021] Please refer to Figures 1 to 5 , the embodiment of the present application provides a kind of outdoor stadium injection molding seat renovation repair equipment, for the seat of small front-back spacing in outdoor stadium, to realize the quick repair of seat seat area, the equipment includes a shell 1 and is used for repair gun head 2, the inside of shell 1 is slidably installed with the support assembly 4 for disposing gun head 2, adjusting assembly 5 is arranged on support assembly 4 and is used for adjusting gun head 2 with the inner wall of shell 1 corresponds, the inside of shell 1 is provided with the control assembly 3 of active adhesion with support assembly 4.

[0022] In the above structure, the orientation of gun head 2 in initial state is downward, which can automatically form correspondence with the seat cushion surface when moving horizontally.And gun head 2 is downward in initial state, which can also avoid injury to workers and the possibility of safety accidents.

[0023] When control assembly 3 is started, support assembly 4 and adjusting assembly 5 can be first translated to seat and approach, at this time, support assembly 4 drives gun head 2 to move synchronously, and gun head 2 can realize quick repair of seat cushion surface in this process, and finally reach the junction of seat cushion surface and back surface.When gun head 2 reaches the junction, adjusting assembly 5 can contact with the inner wall of shell 1, and then cooperate with support assembly 4 to change the orientation of gun head 2, so that it changes from downward state to horizontal state, at this time, gun head 2 can also automatically form correspondence with the back surface of seat. Then the start of control assembly 3 can drive support assembly 4 and adjusting assembly 5 to rise along the back surface of seat, at this time, gun head 2 can realize quick repair of seat back surface.

[0024] Further, the top of shell 1 is provided with air source 7 connected with gun head 2, and stable air supply is realized between air source 7 and gun head 2 through hose joint, and the hose can form self-adaptation when gun head 2 is adjusted in orientation state and horizontal state, without interfering with the movement of gun head 2.

[0025] In the embodiment, the shell 1 is detachably mounted on a trolley (not shown in the figure), and the staff can realize the rapid movement and stop of the shell 1 between the front and rear rows of seats through the trolley. Among them, the trolley, the gun head 2 and the gas source 7 are all existing mature technologies, and will not be described in detail here.

[0026] Referring to Figures 2 to 4 In the embodiment, preferably, the support assembly 4 includes a circular rod 401 which is movably attached to the control assembly 3 and is in sliding fit with the inner wall of the shell 1, and the outer surface of the circular rod 401 is sleeved with a base 402 for accommodating the adjusting assembly 5 and in rotational fit with the gun head 2. In the embodiment, the base 402 is designed in T shape and a first spring 403 is fixedly installed on the surface of the base 402 and abuts against the inner wall of the shell 1. The first spring 403 is not fixedly connected with the inner wall of the shell 1, and can keep synchronous movement with the base 402 when the base 402 moves up and down.

[0027] Further, the inner wall of the shell 1 is provided with an L-shaped groove 101 for the sliding of the circular rod 401. The L-shaped groove 101 is formed in correspondence with the seat cushion surface and the backrest surface as a whole, and is used to drive the circular rod 401 to first translate towards the seat and then vertically rise along the backrest surface of the seat. When the circular rod 401 approaches the seat, the first spring 403 is pressed by the base 402, and when the circular rod 401 rises along the seat, the first spring 403 is synchronously moved by the base 402.

[0028] Referring to Figures 2 to 4 In the embodiment, preferably, the control assembly 3 includes a gas cylinder 301 which is fixedly installed on the inner bottom wall of the shell 1, and an inclined block 302 which is movably attached to the outer surface of the circular rod 401 is fixedly installed on the output shaft of the gas cylinder 301. The side of the inclined block 302 close to the gun head 2 is provided with a plane 303 which is in size adaptation with the circular rod 401, and the top of the inclined block 302 is provided with an avoiding groove 304 which avoids the base 402. When the circular rod 401 drives the base 402 to move, the avoiding groove 304 makes the inclined block 302 not interfere with the base 402.

[0029] In the above structure, the plane 303 corresponds to the vertical part of the L-shaped groove 101 in up-down direction and is in size adaptation (left-right size), that is, after the circular rod 401 falls on the plane 303, if the inclined block 302 rises, the circular rod 401 can automatically enter the vertical part of the L-shaped groove 101. The inclined part of the inclined block 302 corresponds to the horizontal part of the L-shaped groove 101 in up-down direction and is in size adaptation (left-right size), and when the inclined block 302 rises, the inclined block 302 can push the circular rod 401 to move along the horizontal part of the L-shaped groove 101.

[0030] Referring to Figures 3 to 5In the embodiment, preferably, the adjusting assembly 5 comprises a guide column 501 slidingly installed on the surface of the base 402 close to the side of the gun head 2, a second spring 502 fixedly installed between the guide column 501 and the base 402, the second spring 502 enabling the guide column 501 to have a tendency to extend out of the base 402, and a pull rope 503 fixedly connected to the guide column 501 and wound around the gun head 2; when the guide column 501 moves with the base 402 and contacts the inner wall of the shell 1, the guide column 501 is retracted into the base 402 and presses the second spring 502, and the guide column 501 also pulls the pull rope 503 when moving, and the pull rope 503 enables the gun head 2 to change from the vertical downward state to the horizontal state.

[0031] The downward state of the gun head 2 in the initial state is automatically realized by gravity, and no resetting part is needed for the downward state of the gun head 2.

[0032] In use, the shell 1 is moved to the front side of the seat by the trolley and the gun head 2 corresponds to the seat cushion, then the cylinder 301 is started to drive the inclined block 302 to rise, the inclined block 302 drives the round rod 401 to move along the horizontal part of the L-shaped groove 101 when rising, the round rod 401 drives the guide column 501 and the gun head 2 to move synchronously through the base 402, so that the gun head 2 translates along the seat cushion in the downward state, and the gun head 2 can realize the rapid repair of the seat cushion in the process.

[0033] When the gun head 2 moves to the junction of the seat cushion and the backrest surface, the round rod 401 falls on the plane 303, the guide column 501 contacts the inner wall of the shell 1 and is retracted into the base 402, the guide column 501 pulls the pull rope 503 to enable the gun head 2 to rotate based on the base 402, and the gun head 2 changes from the downward state to the horizontal state and points to the backrest surface of the seat. At this time, the cylinder 301 is started to drive the inclined block 302 to continue rising, and the plane 303 pushes the round rod 401 to rise along the vertical part of the L-shaped groove 101, so that the gun head 2 moves along the backrest surface of the seat in the horizontal state, and the gun head 2 can realize the rapid repair of the backrest surface of the seat in the process.

[0034] Further, the second gun head 2 can be arranged on the other side of the shell 1 and synchronously lifted with the base 402, and the left and right movement of the base 402 does not affect the second gun head 2. The square frame installed on the shell 1 can be used to achieve the above-mentioned effect. The square frame is adapted to the thickness of the base 402 and can be moved left and right by the base 402. The up and down movement of the base 402 drives the square frame to move synchronously. At this time, the second gun head 2 is arranged on the other side of the shell 1 and corresponds to the back of the seat. When the base 402 moves, the seat cushion surface and the back surface of the seat on one side can be repaired quickly, and the back surface of the seat on the other side can also be repaired quickly. Of course, the above-mentioned one side and the other side are based on the front and back of the seat.

[0035] In summary, through the cooperation of the round rod 401, the L-shaped groove 101, the inclined block 302, and the base 402, the gun head 2 can be translated in a downward state first, and then the gun head 2 can be lifted in a horizontal state. The seat cushion surface and the back surface of the seat can be repaired quickly. The overall structure is combined in the shell 1, and the movement and direction adjustment of the gun head 2 can realize quick repair. The distance between the front and back seats is more adaptable, and the structure is compact, so the marginal seat can also be repaired effectively. The movement of the L-shaped track of the gun head 2 can correspond to the shape of the seat effectively, and the gun head 2 can be as close as possible to the seat repair area, thereby ensuring the renovation repair effect of the seat, and the practicability is higher. Embodiment

[0036] Please refer to Figures 1 to 8 On the basis of the first embodiment, considering that the gun head 2 will spray to a range extending outwardly from the gun head 2 during use, in order to realize effective use and saving use of the gun head 2 and the gas source 7, the gun head 2, the round rod 401, and the base 402 are improved: in the normal state, the gun head 2 includes a shunt pipe and a plurality of gun barrels fixedly installed on the shunt pipe. The shunt pipe is rotatably installed on the base 402, and the gas source 7 is connected to the shunt pipe through a hose, thereby realizing gas supply to the plurality of gun barrels.

[0037] Further, the outer surface of the round rod 401 is provided with a circulating groove 405, and the inner part of the base 402 is fixedly provided with an embedded block 406 which is slidingly engaged with the circulating groove 405, when the round rod 401 rotates, the base 402 can be driven to reciprocate along the axial direction of the round rod 401 through the circulating groove 405 and the embedded block 406. In order to realize the rotation of the round rod 401, the end part of the round rod 401 is fixedly provided with a gear 404, and the inner part of the L-shaped groove 101 is fixedly provided with a rack (not shown in the figure) which is drivingly connected with the gear 404, when the round rod 401 moves along the L-shaped groove 101, the rotation of the round rod 401 can be realized through the rack and the gear 404, and the rotation of the round rod 401 will not affect the movement of the inclined block 302. It can be understood that the rack is L-shaped due to the shape of the L-shaped groove 101.

[0038] With reference to Figure 7 and Figure 8 In the present embodiment, the circulating groove 405 is designed as a whole V shape when it is unfolded, so that the round rod 401 can drive the base 402 to reciprocate along the axial direction of the round rod 401 when it rotates through the embedded block 406. In order to avoid the self-rotation of the base 402 based on the round rod 401, an extension rod (not shown in the figure) can be fixedly installed on the base 402, and the end part of the extension rod away from the base 402 is magnetically connected with the inner wall of the shell 1, forming an adsorption to avoid the deviation of the base 402 and keeping it in a horizontal state.

[0039] Further, the surface of the shell 1 is fixedly provided with two arc-shaped edges 6 which are symmetrically distributed and correspond to the position of the shunt pipe, the sides of the shunt pipe can be bent and deformed, when the base 402 drives the shunt pipe to contact with any one of the arc-shaped edges 6, the sides of the shunt pipe can be bent and drive the most marginal barrel to move synchronously, so that the most marginal barrel forms an inwardly inclined angle offset, which can effectively correspond to the side of the seat. The arc-shaped edge 6 has a certain length in the up-down direction, so that the up-down movement of the barrel head 2 can correspondingly contact with the arc-shaped edge 6.

[0040] When in use, the gun head 2 can be first translated in a downward state and then lifted in a horizontal state to complete the repair through the structures of the round rod 401, the L-shaped slot 101 and the base 402, and the working process and effect are the same as those in Embodiment One, which will not be repeated here. The difference lies in that when the inclined block 302 and the plane 303 drive the round rod 401 to move along the L-shaped slot 101, the round rod 401 can also rotate through the gear 404 and the rack, and when rotating, the round rod 401 drives the base 402 to reciprocate along the axial direction of the round rod 401 through the circulation groove 405 and the embedded block 406, and the base 402 drives the shunt pipe and the plurality of gun barrels to move synchronously, and the shunt pipe can contact the arc-shaped edge 6 when moving to the two side edges, so that the most marginal gun barrel also forms an inward inclination adjustment, and the most marginal gun barrel can form effective correspondence with the side edges of the seat when moving to the two side edges.

[0041] Compared with Embodiment One, on the basis of the gun barrel being first translated in a downward state and then lifted in a horizontal state to complete the repair, the gun barrel can also be driven to move left and right along the seat through the cooperation of the structures of the round rod 401, the base 402, the circulation groove 405 and the gear 404, thereby effectively reducing the number of gun barrels used and saving the use of gas, and effectively reducing the overall working cost. The overall scheme is combined with the movement of the round rod 401, and the most marginal gun barrel also forms an inward inclination, thereby forming effective correspondence with the two side edges of the seat, thereby achieving effective repair of the overall seat and ensuring the overall repair effect, and the applicability is stronger. Embodiment

[0042] Please refer to Figures 1 to 10 On the basis of Embodiment Two, considering that the frontmost surface of the seat (the front side of the cushion surface) cannot form good correspondence due to the downward state of the gun barrel, and the uppermost surface of the seat (the back surface) cannot form good correspondence due to the horizontal state of the gun barrel, the repair effect of the overall seat can be further improved.

[0043] Therefore, the guide column 501 is improved: at this time, the guide column 501 includes a cross rod 5001 and a wedge block 5003 which are in sliding cooperation with the base 402, the pull rope 503 is fixedly connected to the surface of the wedge block 5003 and the second spring 502 is also arranged between the wedge block 5003 and the base 402, and the bottom of the guide column 501 is fixedly installed with a triangular block 5002 which is in active fit with the wedge block 5003; when the guide column 501 moves to any side along the length direction thereof, the wedge block 5003 can be driven to descend based on the base 402 and pull the pull rope 503 through the triangular block 5002.

[0044] In the above structure, the sliding direction of the cross rod 5001 based on the base 402 is perpendicular to the direction of the wedge block 5003 based on the base 402, and the top of the wedge block 5003 is designed in a V shape to adapt to the triangle.

[0045] Further, the end of the crossbar 5001 close to the barrel is larger than the end of the crossbar 5001 far from the barrel in the length of the extension of the base 402, and the end of the crossbar 5001 far from the barrel is in contact with the inner wall of the shell 1 in the initial state, that is, the end of the crossbar 5001 far from the barrel is retracted in the base 402 in the initial state, so that the barrel is in an inclined state pointing to the frontmost surface of the seat in the initial state. When the base 402 is moved by the round rod 401, the second spring 502 makes the wedge block 5003 rise and the two ends of the crossbar 5001 restore the state of extending from the two sides of the base 402, and at this time the barrel is in a vertical downward state.

[0046] Further, the inner wall of the shell 1 can also be fixedly installed with a protrusion (not shown in the figure) corresponding to the topmost part of the L-shaped groove 101, so that when the base 402 reaches the top of the L-shaped groove 101, the end of the crossbar 5001 close to the barrel can be in contact with the protrusion, forming the effect that the end of the crossbar 5001 far from the barrel is in contact with the inner wall of the shell 1 in the initial state, that is, the barrel is in an inclined state pointing to the topmost surface of the seat (the upper part of the back surface).

[0047] In use, the barrel head 2 is first translated in a downward state and then lifted in a horizontal state to complete the repair by the structures of the round rod 401, the L-shaped groove 101 and the base 402; the barrel can also be moved left and right along the seat to repair by the structures of the round rod 401, the base 402 and the gear 404, and the working process and effect are the same as in Embodiment One, which will not be repeated here. The difference is that when the base 402 is in the initial state, the end of the crossbar 5001 far from the barrel is in contact with the inner wall of the shell 1 and retracted in the base, so that the barrel is in an inclined state pointing to the frontmost surface of the seat in the initial state; then the barrel is turned to a downward state to complete the repair of the seat cushion surface, and then to a horizontal state to complete the repair of the back surface. Then when the end of the crossbar 5001 close to the barrel is in contact with the protrusion, the barrel is turned to an inclined state pointing to the topmost surface of the seat and completes the repair.

[0048] It should be noted that the inclination angle of the barrel is mainly controlled by the movement of the triangular block 5002 driving the wedge block 5003, and in the normal state, the inclination angle of the barrel is mainly 45 degrees.

[0049] Compared with the second embodiment, through cooperation of the cross rod 5001, the triangular block 5002, the base 402 and the wedge block 5003 and the like, the barrel can be in a tilting state corresponding to the frontmost surface and the uppermost surface of the seat, thereby effectively repairing the whole surface of the seat and further ensuring the repair effect and reducing the later intervention repair of the staff. The overall scheme is combined with the adjustment of the barrel, and the tilting of the barrel can further reduce the gas usage and the cost, thereby ensuring the overall economic benefit and meeting more needs in actual use.
