Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment detection technology, specifically an adjustable fire protection maintenance device. Background Technology

[0002] A smoke gun is needed for testing and maintaining fire smoke detectors. The smoke gun is used to test the alarm function of the smoke detectors. By applying simulated smoke to the detector, it is tested whether the detector can send an alarm signal in a timely manner.

[0003] According to application number 202223392729.7 published on the China Patent Network, this application relates to the technical field of fire detection equipment, and improves the problem of the cumbersome process of splicing the handheld handle and storing fire smoke guns during use. It discloses a fire smoke gun with a smoke generator and a handheld handle. The handheld handle includes a control rod, a connecting rod, and an extension rod. The smoke generator is located at one end of the connecting rod. The control rod has a button. One end of the extension rod is hinged to the end of the connecting rod away from the smoke generator. One end of the control rod is connected to the other end of the extension rod. One end is hinged, and the hinge points of the connecting rod and the extension rod, as well as the hinge points of the control rod and the extension rod, are located on both sides of the extension rod. This application allows users to easily assemble the handle before using the fire extinguisher and also makes it convenient for users to fold and store the handle after using the fire extinguisher. However, the extension method of this fire extinguisher is to achieve the length extension by splicing hinges together. This makes it easy for the hinges to break when the user uses the fire extinguisher and it collides with an object, causing the fire extinguisher head to fall off and fail to extend, thus reducing the practicality of the fire extinguisher.

[0004] Therefore, it is necessary to improve the fire smoke gun to avoid the phenomenon that the hinge is prone to breakage when the fire smoke gun is connected by only a hinge, which is prone to breakage when it collides with an object. Utility Model Content

The surface of the push plate 10 is slidably connected to the inner wall of the transmission groove 9. A pressure block 11 is fixedly connected to the outer side of the push plate 10. The outer side of the pressure block 11 extends through to the outside of the connecting rod 3 and is slidably connected to the inner wall of the connecting rod 3. A limiting block 12 located to the right of the pressure block 11 is fixedly connected to the outer side of the push plate 10. The outer side of the limiting block 12 extends through the connecting rod 3 and into the interior of the limiting block 6. The surface of the limiting block 12 contacts the inner wall of the limiting block 6. An extension block 13 located to the right of the limiting block 12 is fixedly connected to the outer side of the push plate 10. The outer side of the extension block 13 extends through to the outside of the connecting rod 3 and is slidably connected to the inner wall of the connecting rod 3.

[0029] As a technical optimization of this utility model, by setting the transmission groove 9, push plate 10, pressure block 11, limit block 12 and extension block 13, the position of the limit block 6 can be fixed, avoiding the phenomenon that the limit block 6 is prone to loosening if it is limited by its own friction force.

[0030] refer to Figure 4 Multiple guide rods 14 are fixedly connected laterally inside the transmission groove 9. The guide rods 14 pass through the push plate 10 and are slidably connected to the push plate 10.

[0031] As a technical optimization of this utility model, by setting the guide rod 14, the push plate 10 can be guided, so as to avoid the phenomenon of tilting and jamming when the push plate 10 moves.

[0032] refer to Figure 6 Two springers 15 are arranged horizontally on the inner wall of the transmission groove 9. The front and rear sides of the springers 15 are fixedly connected to the inner side of the push plate 10.

[0033] As a technical optimization of this utility model, by setting the springback device 15, the push plate 10 can be moved outward automatically, thereby improving the performance of the push plate 10.

[0034] refer to Figure 6The front and rear sides of the connecting rod 3 are provided with protective pads 16, and the inner side of the protective pads 16 is fixedly connected to the outer side of the pressure block 11.

[0035] As a technical optimization of this utility model, by setting the protective pad 16, it is easier for the user to press the pressure block 11 inward, thus improving the user's comfort.

[0036] refer to Figure 4 A stop 17 is fixedly connected to the right side of the limiting rod 5, and the surface of the stop 17 is slidably connected to the inner wall of the extension rod 2.

[0037] As a technical optimization of this utility model, by setting the stop 17, the limiting rod 5 can be limited, thus preventing the limiting rod 5 from detaching from the extension rod 2.

[0038] refer to Figure 6 Friction pads 18 are fixedly connected to the outer side of the limiting block 12 and the outer side of the extension block 13. The friction pads 18 are used in conjunction with the limiting block 12 and the extension block 13.

[0039] As a technical optimization of this utility model, by setting the friction pad 18, the limiting block 12 and the extension block 13 can make closer contact with the inner wall of the limiting block 6, thereby increasing the contact area between the limiting block 12 and the extension block 13 and the limiting block 6.

[0040] refer to Figure 3 The front and rear sides of the inner wall of the limiting block 6 are provided with slots 19, and the outer side of the friction pad 18 extends into the inside of the slot 19 and contacts the inner wall of the slot 19.

[0041] As a technical optimization of this utility model, by setting the slot 19, the friction pad 18 can be limited, thereby improving the stability of the friction pad 18 when it is limited.

[0042] The working principle and usage process of this utility model are as follows: When in use, first press the pressure block 11 inward. The pressure block 11 drives the push plate 10 to move inward. The push plate 10 drives the limiting block 12 and the extension block 13 to move inward, so that the limiting block 12 moves away from the limiting block 6. After it moves away, the user pushes the limiting block 6 to the right. The limiting block 6 drives the push rod 7 to move to the right. The push rod 7 drives the fixing block 8 to move to the right. The fixing block 8 drives the extension rod 2, which slides on the surface of the limiting rod 5, to move to the right. After moving to the limit position, release the pressure block 11. The spring force of the spring return device 15 drives the push plate 10 to move outward. The push plate 10 drives the extension block 13 to move outward, so that the extension block 13 is inserted into the interior of the limiting block 6 to fix the limiting block 6.

[0043] In summary, this adjustable fire protection maintenance device, by setting a limiting rod 5, can guide the extension rod 2 and prevent it from wobbling during extension; by setting a limiting block 6, a push rod 7, and a fixing block 8, it facilitates the user's pushing and pulling of the extension rod 2, improving user comfort; by setting a push plate 10, a pressure block 11, a limiting latch 12, and an extension latch 13, it can fix the limiting block 6 and prevent it from moving arbitrarily. This device achieves efficient extension and solves the problem that the current method of extending the fire smoke gun by splicing hinges together makes it easy for the hinges to break when the fire smoke gun collides with an object, causing the fire smoke gun head to fall off and thus failing to extend, reducing the practicality of the fire smoke gun.
