[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] See also Figures 1-6 , shows a schematic diagram of the structure of a clamping structure of a car interior trim molding die according to the present invention, please refer to Figures 1-6 , a detailed introduction is given to a clamping-type skeleton clamping structure of an automobile interior trim molding die.

[0029] The two assembling plates 130 are fixed on the rod body of the rotating rod 120, and the left sides of the two assembling plates 130 are commonly fixed with the side plates 140 on the left sides of the two assembling plates 130. A torsion spring 150 is sleeved on the outer gap of the rod body of the rotating rod 120, and the two ends of the torsion spring 150 are respectively against the left side wall of the side plate 100 and the right side wall of the side plate 2 140. The upper ends of the sides facing the side plates 100 and 140 are respectively provided with clamping blocks 160. The two clamping blocks 160 are pressed against each other to form a clamping force under the push of the torsion spring 150; a locking component is provided on the rear assembly plate 110, and the locking component is used to lock the rotating rod 120;

[0030] The locking assembly includes a circular mounting groove 200 provided on the rear side wall of the assembly plate 110, the rear end of the rotating rod 120 is located inside the mounting groove 200 and a self-locking gear 210 is protrudingly provided, an adjusting round block 220 is provided in the mounting groove 200 for sliding in the front-to-back direction, the adjusting round block 220 is concavely provided with a self-locking tooth groove 230 near the self-locking gear 210, the shape of the self-locking tooth groove 230 is adapted to the self-locking gear 210 and is provided for the self-locking gear 210 to be inserted into, a circle of card grooves 240 is provided on the inner side of the mounting groove 200 with its own center as the center, and a circle of latch teeth 250 is provided on the outer wall of the adjusting round block 220 with its own center as the center, the shape of the latch teeth 250 is adapted to the card groove 240 and is provided for the latch teeth 250 to be inserted into.

[0031] Furthermore, the positions at which both ends of the torsion spring 150 abut against the side panel 1 100 and the side panel 2 140 are lower than the height of the rotating rod 120. After the side panel 100 is pushed by the torsion spring 150, the side panel 100 rotates around the rotating rod 120 as the axis, pressing the two clamping blocks 160 against each other to form a clamping force.

[0032] Furthermore, a first anti-slip pattern 170 is provided on one side of the two clamping blocks 160 that are tightly attached to each other. The surfaces of the two first anti-slip patterns 170 are concave and convex, and the concave and convex surfaces are staggered and engaged with each other. The first anti-slip pattern 170 increases the friction with the clamped object, thereby improving the stability of the connection between the device and the clamped object.

[0033] Furthermore, limiting grooves 180 are formed inwardly on both sides of the shaft of the rotating rod 120, and a rotating hole 190 is formed on the side wall of the assembly plate 110 for the limiting grooves 180 to pass through. The inner side of the limiting groove 180 fits with the inner side of the rotating hole 190 to prevent the rotating rod 120 and the assembly plate 110 from separating.

[0034] Furthermore, a mounting hole 260 is provided at one end of the rotating rod 120 close to the self-locking gear 210, and a spring 270 is provided between the inner cavity side wall of the mounting hole 260 and the inner side wall of the self-locking tooth groove 230. The spring 270 drives the adjusting ball 220 to be inserted into the groove of the mounting groove 200 without being pulled by an external force, and the latch 250 is inserted into the latch groove 240. At this time, the adjusting ball 220 is locked in the mounting groove 200 through the latch groove 240 and the latch tooth 250, and the rotating rod 120 The rear end is locked to the inner side of the adjusting block 220 by the self-locking gear 210 and the self-locking tooth groove 230, so that the rotating rod 120 cannot rotate; after the adjusting block 220 stretches the spring 270, the adjusting block 220 is pulled out from the groove of the mounting groove 200, and the locking tooth 250 is separated from the locking groove 240. At this time, the rotating rod 120 can drive the assembly plate 2 130 to rotate, and then pinch the lower side of the side panel 2 140 and the side panel 1 100 to loosen the two clamping blocks 160, so that the device is separated from the object.

[0035] Furthermore, the outer wall of the adjustment block 220 is provided with a circle of second anti-slip grooves 280, and the second anti-slip grooves 280 are set at a position away from the latch teeth 250. By setting the second anti-slip grooves 280, the friction between the adjustment block 220 and the user's fingers is increased, making it easier to pull the adjustment block 220.

[0036] The user then releases the adjusting knob 220 and the spring 270 drives the adjusting knob 220 to be inserted into the groove of the mounting groove 200, and the latch 250 fits into the latch 240. At this time, the adjusting knob 220 is locked in the mounting groove 200 by the latch 240 and the latch 250, and the rear end of the rotating rod 120 is locked to the inner side of the adjusting knob 220 by the self-locking gear 210 and the self-locking tooth groove 230, so that the rotating rod 120 cannot rotate, thereby further improving the stability after clamping the object.

[0037] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
