Description

Technical Field

[0001] This utility model relates to the field of glass production equipment technology, and in particular to an impact pen for testing glass fragments. Background Technology

[0002] During the production and use of glass, it is necessary to test its impact resistance to ensure its safety and reliability. Traditional glass fragment testing methods usually involve manual operation, using sharp tools to impact the glass. However, this method has the following problems: firstly, it is difficult to guarantee the stability of the impact force; secondly, glass fragments are prone to flying during the test, posing a threat to the personal safety of the operators. Utility Model Content

[0003] (1) Technical solution

[0004] To address the aforementioned technical problems, this utility model provides an impact pen for testing glass fragments, comprising a base, a sleeve, an impact head, an impact rod, a retaining ring, a striking head, and a spring. The base has an anti-slip pad at its bottom and is cylindrical with a semi-circular observation port on one side. The sleeve is vertically mounted inside the base, its upper end penetrating the top of the base and integrally formed with it. The sleeve includes a cylindrical upper part and a conical lower part, with the lower end of the upper part and the upper end of the lower part connected by a thread. The impact rod is housed within the sleeve. The lower end of the impact rod is threadedly connected to the impact head. The upper inner wall of the upper part is provided with the fixing ring. The upper end of the impact rod passes through the fixing ring. The upper end of the impact rod is fixedly connected to the bottom of the striking head. The top of the striking head extends to the outside of the upper end of the sleeve. The spring is sleeved on the impact rod between the bottom of the striking head and the top of the fixing ring. The impact rod is provided with a locking rod for locking the impact rod. The upper part is provided with an inverted L-shaped locking groove for engaging the locking rod. The locking rod passes through the locking groove and extends to the outside of the sleeve.

[0005] Preferably, the outer wall of the upper part is provided with a first external thread, and the inner wall of the lower part is provided with a first internal thread for matching the first external thread.

[0006] Preferably, the upper outer wall of the impact head is provided with a second external thread, and the lower inner wall of the impact rod is provided with a second internal thread that matches the second external thread.

[0007] Preferably, the anti-slip mat is made of rubber.

[0008] (2) Beneficial effects

[0009] This invention provides an impact pen for testing glass fragments. Compared with the prior art, this invention has the following advantages:

[0010] 1. By setting a semi-circular observation port, it is convenient to observe and reduces the risk of injury to operators caused by flying glass fragments; on the other hand, it facilitates the locking between the base and the glass, ensuring the stability of the impact force.

[0011] 2. By setting a locking rod in conjunction with an inverted L-shaped locking groove, when no test is being performed, the locking rod can be lifted and locked onto the horizontal arm of the inverted L-shaped locking groove to protect the impact head. When a test is required, the locking rod can be moved out of the horizontal arm of the inverted L-shaped locking groove and into the vertical arm of the locking groove, which has a certain positioning effect on the impact rod and impact head, preventing the impact head from shifting during the impact process and ensuring the accuracy of the impact test results.

[0012] 3. The lower end of the impact rod is threaded with an impact head. This design allows for the replacement of different impact heads to meet different testing needs. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0018] like Figures 1-3As shown, the glass shard testing impact pen of this utility model includes a base 1, a sleeve 3, an impact head 4, an impact rod 5, a retaining ring 6, a striking head 7, and a spring 8. The base 1 has an anti-slip pad 2 at its bottom. The base 1 is cylindrical and has a semi-circular observation port 11 on one side. The sleeve 3 is vertically disposed inside the base 1. The upper end of the sleeve 3 penetrates the top of the base 1 and is integrally formed with the base 1. The sleeve 3 includes a cylindrical upper part 31 and a conical lower part 32. The lower end of the upper part 31 and the upper end of the lower part 32 are connected by a thread. The impact rod 5 is disposed inside the sleeve 3. The lower end of the striking rod 5 is threadedly connected to the impact head 4. The upper inner wall of the upper part 31 is provided with the fixing ring 6. The upper end of the striking rod 5 passes through the fixing ring 6. The upper end of the striking rod 5 is fixedly connected to the bottom of the striking head 7. The top of the striking head 7 extends to the outside of the upper end of the sleeve 3. The spring 8 is sleeved on the striking rod 5 between the bottom of the striking head 7 and the top of the fixing ring 6. The striking rod 5 is provided with a locking rod 9 for locking the striking rod 5. The upper part 31 is provided with an inverted L-shaped locking groove 10 for engaging the locking rod 9. The locking rod 9 passes through the locking groove 10 and extends to the outside of the sleeve 3.

[0019] The upper part 31 has a first external thread 311 on the lower outer wall, and the lower part 32 has a first internal thread that matches the first external thread 311 on the upper inner wall. This arrangement facilitates disassembly and replacement of the impact head 4.

[0020] The upper outer wall of the impact head 4 is provided with a second external thread 41, and the lower inner wall of the impact rod 5 is provided with a second internal thread that matches the second external thread 41. This arrangement allows for the replacement of different impact heads 4 to meet different testing needs. The anti-slip pad 2 is made of rubber and is designed to prevent slippage, increase friction, and ensure a stable connection between the base 1 and the glass, thus guaranteeing the stability of the impact force.

[0021] In actual operation, the operator holds the base 1 and engages the observation port 11 on the base 1 with the edge of the glass to be tested. Then, an impact hammer strikes the impact head 7, causing the impact head 4 to extend from the lower part 32 of the sleeve 3 to test the glass's impact performance. The semi-circular observation port 11 facilitates observation and reduces the risk of injury to the operator from flying glass fragments; it also facilitates the engagement of the base 1 with the glass, ensuring the stability of the impact force. When not testing, the locking rod 9 can be lifted and engaged with the horizontal arm of the inverted L-shaped locking groove 10 to protect the impact head. When testing is required, the locking rod 9 can be moved out of the horizontal arm of the inverted L-shaped locking groove 10 and into the vertical arm of the locking groove 10, providing a certain positioning effect for the impact rod 5 and the impact head 4, preventing the impact head 4 from shifting during the impact process and ensuring the accuracy of the impact test results. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0022] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
