Description

Technical Field

[0001] This utility model relates to explosion-proof safety windows for mining vehicles, and in particular, explosion-proof safety windows for mining vehicles that are easy to maintain. Background Technology

[0002] In special environments such as mines, it is often necessary to install protective bars on the outside of glass vehicle windows to prevent foreign objects such as gravel from shattering the glass. However, once the protective devices are installed on the vehicle body, they are difficult to remove. Moreover, if the protective bars in the protective devices are deformed by foreign objects and need to be replaced, the entire protective device must be replaced, which is extremely inconvenient for maintenance. Summary of the Invention

[0003] The purpose of this invention is to provide a safe and explosion-proof window for mining vehicles that is easy to maintain and allows for convenient replacement of the protective rod.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] The easy-to-maintain safety explosion-proof window for mining vehicles includes a glass window installed on the vehicle body and a protective frame set on the outside of the glass window. The protective frame is fixedly connected to the vehicle body. The protective frame has an upper crossbeam and a lower crossbeam located below the upper crossbeam. The upper crossbeam is provided with multiple positioning holes and multiple connecting holes that correspond one-to-one with and communicate with the corresponding positioning holes. The diameter of the positioning holes is larger than the diameter of the connecting holes, and a positioning step is formed between the positioning holes and the connecting holes. The lower crossbeam is provided with a threaded groove, and an internal thread is provided in the threaded groove. A protective rod is inserted into the connecting hole. The lower end of the protective rod is provided with a connecting part, which extends into the threaded groove and is threadedly connected to the threaded groove. The upper end of the protective rod is provided with a positioning boss, which transitionally fits with the positioning hole. The diameter of the connecting hole is larger than the diameter of the protective rod.

[0006] With the above structure, when the guard rod is deformed by a collision with a foreign object, simply rotate the cover of the guard rod to separate the lower end of the guard rod from the lower crossbeam. Since the diameter of the connecting hole is larger than the diameter of the guard rod, even if the guard rod is bent and deformed, it can be easily pushed upward from the connecting hole and removed. Then, the intact guard rod can be replaced and tightened. This utility model can easily and quickly replace the deformed guard rod, and the maintenance process is simple, fast, and efficient.

[0007] Preferably, in order to ensure that the deformed protective rod can still be removed, the diameter of the connecting hole is D, the diameter of the protective rod is d, and the ratio of D to d is greater than 1.5.

[0008] Preferably, in order to reduce wear between the positioning boss and the positioning hole, a rubber ring is provided on the outer side of the positioning boss. Attached Figure Description

[0009] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] Figure 2 This is a schematic diagram of the assembly of the protective rod of this utility model. Detailed Implementation

[0012] like Figure 1 and Figure 2 As shown, the easy-maintainable explosion-proof safety window for mining vehicles of this utility model includes a glass window 2 installed on the vehicle body 1, and a protective frame 3 set on the outside of the glass window. The protective frame is fixedly connected to the vehicle body. The protective frame has an upper crossbeam 4 and a lower crossbeam 5 located below the upper crossbeam. The upper crossbeam is provided with a plurality of positioning holes 6 and a plurality of connecting holes 7 corresponding to and communicating with the corresponding positioning holes. The diameter of the positioning holes is larger than the diameter of the connecting holes. A positioning step 8 is formed between the positioning holes and the connecting holes. The lower crossbeam is provided with a threaded groove 9. The threaded groove is provided with an internal thread. A protective rod 10 is inserted into the connecting hole. The lower end of the protective rod is provided with a connecting part 11. The connecting part extends into the threaded groove and is threadedly connected to the threaded groove. The upper end of the protective rod is provided with a positioning boss 12. The positioning boss is transitionally fitted with the positioning hole. The diameter of the connecting hole is larger than the diameter of the protective rod.

[0013] In some embodiments, the diameter of the connecting hole is D, the diameter of the protective rod is d, and the ratio of D to d is greater than 1.5.

[0014] In some embodiments, a rubber ring 13 is provided on the outer side of the positioning boss.

[0015] With the above structure, when the guard rod is deformed by a collision with a foreign object, simply rotate the cover of the guard rod to separate the lower end of the guard rod from the lower crossbeam. Since the diameter of the connecting hole is larger than the diameter of the guard rod, even if the guard rod is bent and deformed, it can be easily pushed upward from the connecting hole and removed. Then, the intact guard rod can be replaced and tightened. This utility model can easily and quickly replace the deformed guard rod, and the maintenance process is simple, fast, and efficient.

[0016] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
