Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, in particular to a building fire protection pipe fitting with high buffering performance. Background Art

[0002] Fire fittings refer to pipe materials used in firefighting to connect firefighting equipment and instruments, and to transport fire-fighting water, gas or other media. Due to special needs, there are special requirements for the thickness and material of fire fittings, and building fire fittings are one of them. At present, in the field of construction, building fire fittings are required to have the ability to resist and withstand impacts. However, in the prior art, although most of them can achieve the buffering performance of the fittings by installing shock-absorbing devices, during the implementation of the above-mentioned prior art, the shock-absorbing devices still directly act on the fitting body, resulting in an insufficiently obvious shock-absorbing effect and low buffering performance. For example, the application number CN201922375675.5 is a building fire fitting that can offset impact stress. It can be seen from the specification and the drawings in the specification in the above-mentioned utility model patent that after being impacted, after being damped by the shock-absorbing device, the impact force received by the second connecting block still directly acts on the fitting body, and there is no shock-absorbing effect here. Therefore, when the current existing technology sets the shock-absorbing device for the pipe fitting, the shock-absorbing effect of the components in direct contact with the pipe fitting is ignored, resulting in that the impact force after shock absorption has no shock-absorbing effect when it acts on the components in direct contact with the pipe fitting, that is, it directly acts on the pipe fitting body, thereby making the buffering performance of the pipe fitting weaker.

[0003] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0004] In view of the above-mentioned defects, the purpose of the utility model is to provide a building fire protection pipe fitting with high buffering performance, which can achieve shock absorption of impact force through the connection between the sliding rod and the shock absorbing plate. At the same time, due to the action of several second springs on the inner wall of the shock absorbing plate, the impact force can continue to be damped before acting on the pipe fitting, thereby improving the buffering performance of the pipe fitting.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a building fire protection pipe fitting with high buffering performance, including a pipe fitting, a shock-absorbing device is installed on the outside of the pipe fitting, and the shock-absorbing device includes an arc plate symmetrically installed on the outside of the pipe fitting, and the inner wall of the arc plate is hinged with a sliding rod, and the end of the sliding rod away from the inner wall of the arc plate is located in a slide groove, and a first spring is installed in the slide groove. The slide groove is located on the shock-absorbing plate, and a plurality of second springs are installed on the side of the shock-absorbing plate away from the slide groove, and the second springs are in contact with the outer surface of the pipe fitting.

[0006] According to the building fire protection pipe fitting with high buffering performance of the utility model, the arc plate is divided into an upper arc plate and a lower arc plate.

[0007] According to the building fire protection pipe fitting with high buffering performance of the utility model, the upper arc plate and the lower arc plate are connected by a fixing piece.

[0008] According to the building fire protection pipe fitting with high buffering performance of the utility model, a bottom groove is provided inside the slide groove, and the width of the bottom groove is greater than the width of the notch on the upper surface of the slide groove.

[0009] According to the building fire protection pipe fitting with high buffering performance of the utility model, a connecting block is installed at the bottom end of the sliding rod, and the connecting block is located in the bottom groove.

[0010] According to the building fire protection pipe fitting with high buffering performance of the utility model, one end of the first spring is connected to the inner side of the slide groove, and the other end is connected to the side surface of the connecting hole.

[0011] The utility model provides a building fire protection pipe fitting with high buffering performance, which achieves shock absorption of impact force through a shock absorbing device inside the arc plate. At the same time, by utilizing the connection relationship between the second spring and the pipe fitting, it can avoid the shock absorbing device from directly acting on the pipe fitting, so that the impact force after shock absorption can still obtain the shock absorption effect when it is transmitted to the second spring that is in direct contact with the pipe fitting, thereby improving the buffering performance of the pipe fitting.

[0020] See also Figure 1-Figure 4 The utility model provides a building fire protection pipe fitting with high buffering performance, including a pipe fitting 7, a shock absorbing device is installed on the outside of the pipe fitting 7, and the shock absorbing device includes an arc plate 1 symmetrically installed on the outside of the pipe fitting 7. The symmetrically installed arc plate 1 can have a more comprehensive shock absorbing effect on the pipe fitting 7. The inner wall of the arc plate 1 is hinged with a sliding rod 2. When the arc plate 1 is subjected to impact force, the force can be diluted by sliding the hinged sliding rod 2. The end of the sliding rod 2 away from the inner wall of the arc plate 1 is located in a slide groove 3. A first spring 4 is installed in the slide groove 3. The slide groove 3 can provide a distance for the sliding of the sliding rod 2 and prevent it from coming off. The first spring 4 is deformed by the force when the sliding rod 2 slides, so as to play a rebound role for the sliding rod 2 and achieve a shock-absorbing effect. The slide groove 3 is located on the shock-absorbing plate 5. A plurality of second springs 6 are installed on the side of the shock-absorbing plate 5 away from the slide groove 3. The second springs 6 are in contact with the outer surface of the pipe 7. Through the contact between the second springs 6 and the outer surface of the pipe 7, when the impact force is transmitted from the shock-absorbing plate 5 to the second springs 6, the second springs 6 will be deformed. In the process of the second springs 6 being deformed, the rebound force can be used to dilute the impact force of the shock-absorbing plate 5, thereby avoiding the impact force from directly acting on the pipe 7, thereby improving the buffering performance of the pipe 7.

[0021] Preferably, the arc plate 1 of the present invention is divided into an upper arc plate 1-1 and a lower arc plate 1-2, and the upper arc plate 1-1 and the lower arc plate 1-2 can better fix the pipe 7 and facilitate installation and disassembly.

[0022] In addition, the upper arc plate 1-1 and the lower arc plate 1-2 of the utility model are connected by a fixing member 1-3, and the fixing member 1-3 can provide fixation for the upper arc plate 1-1 and the lower arc plate 1-2, thereby facilitating the connection and disassembly of the upper arc plate 1-1 and the lower arc plate 1-2.

[0023] Furthermore, a bottom groove 3-1 is provided inside the slide groove 3 of the utility model, and the width of the bottom groove 3-1 is greater than the width of the notch 3-2 on the upper surface of the slide groove 3. The width difference between the bottom groove 3-1 and the slide groove 3 can better position one end of the sliding rod 2 to prevent the sliding rod 2 from falling off.

[0024] Better yet, a connecting block 2-1 is installed at the bottom end of the sliding rod 2 of the utility model, and the connecting block 2-1 is located in the bottom groove 3-1. The sliding rod 2 can be better positioned through the connecting block 2-1.

[0025] Finally, one end of the first spring 4 of the utility model is connected to the inner side of the slide groove 3, and the other end is connected to the side of the connecting block 2-1. Through the connection of the first spring 4, the first spring 4 can be more easily subjected to the extrusion force, and it is also convenient for the first spring 4 to rebound against the connecting block 2-1.

[0026] The working principle of this utility model:

[0027] First, the building fire protection pipe fittings have been installed in a fixed position, and then the staff selects a position that is easily impacted in the local part of the building fire protection pipe fittings, and sleeves the upper arc plate 1-1 and the lower arc plate 1-2 on the outer surface of the pipe fitting 7, so that the second spring 6 in the arc plate 1 contacts the outer surface of the pipe fitting 7, and then connects and fixes the upper arc plate 1-1 and the lower arc plate 1-2 through the fixing member 1-3. When impacted, the arc plate 1 will move. When moving, the sliding rod 2 hinged to the inner wall of the arc plate 1 will slide along the sliding groove 3, and the sliding of the sliding rod 2 drives the sliding of the connecting block 2-1, and the connecting block 2-1 While sliding, the first spring 4 connected to the connecting block 2-1 will be squeezed, causing the first spring 4 to be deformed. The deformation of the first spring 4 will generate a rebound force, thereby generating a reaction force on the connecting block 2-1, so that part of the impact force is diluted. When the sliding rod 2 moves, it will be forced to squeeze the shock-absorbing plate 5, so that the shock-absorbing plate 5 squeezes the second spring 6. The second spring 6 is deformed by the force and also reacts the rebound force to the shock-absorbing plate 5, thereby diluting the impact force, thereby preventing the pipe fitting 7 from being directly impacted by the impact force, and avoiding the disadvantage that the internal shock-absorbing device directly acts on the pipe fitting 7, resulting in an unclear buffering effect.

[0028] In summary, the utility model provides a building fire protection pipe fitting with high buffering performance, which realizes shock absorption of impact force through the shock absorbing device inside the arc plate. At the same time, by utilizing the connection relationship between the second spring and the pipe fitting, it can avoid the shock absorbing device from directly acting on the pipe fitting, so that the impact force after shock absorption can still obtain the shock absorption effect when it is transmitted to the second spring in direct contact with the pipe fitting, thereby improving the buffering performance of the pipe fitting.

[0029] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
