[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] like Figure 1-4As shown, this utility model is an auxiliary installation tool for locking plastic parts, including a base 1, a cavity block 2, a locking wrench 3, a pin post 4, and an ejector spring 5. The base 1 is connected to the cavity block 2. The locking wrench 3 is connected to the base 1 via the pin post 4 and can rotate axially around the pin post 4. The ejector spring 5 is disposed between the locking wrench 3 and the base 1. The base 1 is provided with a guide post, and the middle of the locking wrench 3 is provided with a guide hole that slides with the pin post 4. The ejector spring 5 is an adjustable spring structure including a spring body and an adjusting screw. The connection between the base 1 and the cavity block 2 provides the locking wrench 3 with room to move, and the pin post 4 limits the axial rotation direction of the locking wrench 3. The adjustable ejector spring 5 can adjust the reset force according to the specifications of the plastic part, so that the wrench can stably reset after operation. Through the above structural cooperation, the problems of wrench offset and non-adjustable reset force are solved, improving assembly stability and adaptability.

[0019] In the above solution, the inner wall of the cavity block 2 is provided with at least two symmetrically distributed positioning protrusions. The cross-section of the positioning protrusions is trapezoidal, which cooperates with the positioning groove on the outer wall of the plastic part. The cooperation between the trapezoidal positioning protrusions and the positioning groove of the plastic part can form a precise positioning when the plastic part is inserted into the cavity block 2, avoiding assembly deviations caused by inaccurate positioning, solving the problem of low positioning accuracy of traditional tooling, and ensuring accurate positioning of the locking piece.

[0020] In the above scheme, the adjusting screw is threadedly connected to the base 1. This threaded connection allows the operator to compress or stretch the spring body by rotating the screw, thereby changing the magnitude of the return force of the ejector spring 5. This adapts to the return force required by different plastic parts, solving the problem of unadjustable return force and enhancing the applicability of the tooling to different products.

[0021] In the above solution, the cavity block 2 is detachably connected to the base 1 by bolts. The bolt connection allows the cavity block 2 to be quickly disassembled and replaced according to the specifications of the plastic part. When different types of plastic parts need to be assembled, only the corresponding cavity block 2 needs to be replaced, which solves the problem of inconvenient maintenance of traditional tooling and improves the versatility and maintenance efficiency of the tooling.

[0022] In the above solution, the handle of the locking wrench 3 is provided with anti-slip texture. The anti-slip texture increases the friction between the handle and the operator's hand, preventing the wrench from slipping during pressing, making the operation more stable, solving the problem of unstable grip during manual operation, and improving the operating feel and assembly efficiency.

[0023] In the above solution, the end of the pin post 4 is provided with an anti-loosening device, which is an elastic retaining ring. The elastic retaining ring is installed at the end of the pin post 4 to prevent the pin post from loosening due to vibration and other factors during long-term use, ensuring a stable connection between the locking wrench 3 and the base 1, solving the problem of the pin post possibly falling off, and ensuring the reliability and service life of the tooling structure.

[0024] Working principle:

[0025] This type of plastic part locking auxiliary installation fixture includes the following process:

[0026] Preparation before assembly: Select the appropriate cavity block 2 according to the specifications of the plastic part to be assembled, and fix it to the base 1 with bolts; rotate the adjusting screw to adjust the return force of the ejector spring 5 to a suitable size according to the required assembly force of the plastic part. The threaded engagement between the adjusting screw and the base 1 can accurately control the spring compression.

[0027] Plastic part positioning: Insert the plastic part along the trapezoidal positioning protrusion on the inner wall of the cavity block 2 until the bottom of the plastic part is in contact with the bottom of the cavity block 2. At this time, the positioning groove on the outer wall of the plastic part is fully engaged with the positioning protrusion, so as to achieve precise positioning of the plastic part and avoid displacement during assembly.

[0028] Locking plate pushing: The operator holds the handle of the locking wrench 3. Due to the anti-slip texture on the handle, the force can be applied stably. Press the locking wrench 3 vertically down to guide the wrench to move down in the vertical direction and prevent lateral deviation. The head of the locking wrench 3 contacts the locking structure inside the plastic part. Continuing to press down pushes the locking plate to the installation position, completing the assembly.

[0029] Wrench reset: After assembly, the operator releases the locking wrench 3, and the push spring 5 pushes the wrench upward to reset it through the adjusted reset force, so that it returns to the initial open state for the next assembly operation; the elastic retaining ring at the end of the pin post 4 always keeps the pin post connection stable, ensuring structural stability during the rotation of the wrench.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
