For ordinary skilled person in the art, the above-mentioned term can be understood by the specific meaning in the utility model through specific circumstances.

[0020] The specific embodiments of the utility model will be described in detail below in combination with the drawings.

[0021] As Figures 1-2 The utility model provides a locking structure for locking product, it includes fixture 100, grommet 200, fastening block 300, first fixed part 400 and wedge block 500, grommet 200 is set on fixture 100, fixture 100 is equipped with assembly hole 101, the first end of first fixed part 400 and assembly hole 101 fixedly cooperate, to with fastening block 300 fixed on fixture 100, grommet 200 and fastening block 300 are used for cooperating clamping product, fastening block 300 is equipped with the movable slot 301 of bottom inclined plane on the side close to the second end of first fixed part 400, wedge block 500 is set in movable slot 301 of fastening block 300 and contacts the second end of first fixed part 400, wherein, wedge block 500 moves on the inclined plane to adjust the tightness of first fixed part 400 fixed state.

[0022] Specifically, product is used to assemble to fixture 100, in this embodiment, fixture 100 selects cylindrical fixture, of course can also adopt other shape structure, fixture 100 has a flange ring protrusion, grommet 200 is set on fixture 100, to be used for extending the flange ring protrusion and enlarge the contact area to product, and grommet 200 can adopt soft material and rough surface, can improve the strong adhesion effect when locking product, grommet 200 and fastening block 300 are used for cooperating clamping product, and the first end of first fixed part 400 passes through fastening block 300 and is fixedly cooperated with assembly hole 101, when first fixed part 400 keeps penetrating assembly hole 101 and approaches fixture 100, fastening block 300 will also approach grommet 200 under the impetus of first fixed part 400, therefore the product clamped between grommet 200 and fastening block 300 is also locked.

[0023] It should be noted that the cooperation of first fixed part 400 and assembly hole 101 is fixedly cooperated in the axial direction of fixture 100. Therefore, in order to further improve the firmness of the locked product, as shown in the drawings, Figure 2As shown, the bottom surface of the movable groove 301 of the whalebone 300 is provided with an inclined surface, one side surface of the wedge-shaped block 500 is adapted to the inclined surface, so that the wedge-shaped block 500 can move smoothly on the inclined surface, and the other side surface of the wedge-shaped block 500 is in contact with the second end of the first fixing member 400, and then the tightness of the fixed state of the first fixing member 400 is adjusted by the radial movement of the jig 100, and the radial direction locking is converted into the axial direction locking mode.

[0024] Further, the locking structure further comprises a plurality of compression rings 600, and the plurality of compression rings 600 are respectively sleeved on the jig 100 and are arranged between the second surface of the product and the fastening block 300. The locking structure further comprises a gasket 700, and the gasket 700 is arranged between the second end of the first fixing member 400 and the wedge-shaped block 500.

[0025] Specifically, the compression ring 600 has the same effect as the gasket 200, and can also be made of soft material and rough surface. When the product is excessively locked, the surface of the product will not be damaged, and due to the soft material, the compression ring 600 will deform to a certain extent after being extruded, and the contact area with the product will also increase, thereby improving the strong adhesion to the product and enhancing the firmness of the locking of the product. The compression ring 600 can be provided with two or more than two, and the actual application is determined. The design of the gasket 700 is the same as that of the existing conventional gasket ring, which will not be described here.

[0026] Further, the first fixing member 400 comprises a screw, and the locking structure further comprises a second fixing member 800. The fastening block 300 is provided with a first hole 302 communicating with the movable groove 301, and the second fixing member 800 is assembled in the first hole 302 and extends to the movable groove 301 and is in contact with the wedge-shaped block 500 to push the wedge-shaped block 500 to move on the movable groove 301.

[0027] Specifically, the second fixing member 800 is the same as the first fixing member 400, and both are screw structures. Since the first fixing member 400 is fixedly connected with the assembly hole 101 in the axial direction, there is a certain error in the thread cooperation, which will cause the pressure applied to the product by the fastening block 300 and the compression ring 600 to be uneven, thereby affecting the locking of the product. Although the compression ring 600 is made of soft material and has a certain deformation ability, it can play a certain role in distributing the pressure, but the effect is small. Therefore, in this embodiment, the movable groove 301 with an inclined surface and the wedge-shaped block 500 are used. It should be noted that the wedge-shaped block is a wedge-shaped gasket 700, which is sleeved on the screw. The fastening block 300 is a fastening ring, which is sleeved on the screw. Therefore, the wedge-shaped block 500 moves on the inclined surface under the pushing of the second fixing member 800, so as to correspondingly adjust the tightness of the clamping and locking of the product by the fastening block 300 and the gasket 200.

[0028] Further, the locking structure further comprises a third fixing member 900, the screw is provided with a clamping post 401, the fastening block 300 is provided with a second hole 303 which is communicated with the central axis hole of the fastening ring, and the third fixing member 900 is assembled in the second hole 303 and extends into the central axis hole and abuts against the clamping post 401.

[0029] Specifically, the third fixing member 900 is also a screw structure, since in the embodiment, the jig 100 clamps the product, and the corresponding application scene is a rotary machining work, which brings a certain rotary force to the first fixing member 400, and the rotary force is easy to cause the first fixing member 400 to be loose, and further affect the firmness of the fastening block 300 and the gasket ring 200 clamping the product, therefore, the third fixing member 900 abuts against the clamping post 401 on the first fixing member 400, so as to reduce the influence of the rotary force on the first fixing member 400.

[0030] The above is one or more embodiments provided in combination with specific contents, and it is not considered that the specific implementation of the utility model is limited to these descriptions. Any approximation, similarity or replacement of the method and structure of the utility model, or any technical deduction or replacement under the concept of the utility model, should be regarded as the protection range of the utility model.
