Description

Technical Field

[0001] This utility model relates to the field of building component connection technology, and in particular to a novel chimney flue fixing structure. Background Technology

[0002] Flue pipes are common smoke extraction and ventilation systems in modern buildings, and their installation quality directly affects the building's safety and functionality. During installation, flue pipes typically require fixing devices to securely mount them to supporting structures such as walls.

[0003] Existing fixing devices mostly use simple U-shaped clamps or split-type fixtures, locked with bolts. This method has significant shortcomings in operation. Operators need to manually adjust the position of the flue pipe to center it in the fixture before tightening the bolts one by one. The entire process is not only tedious and time-consuming, but it is also difficult to ensure the uniform application of clamping force, which can easily lead to uneven stress on the flue pipe and cause it to tilt, affecting the reliability of the fixing effect. When it is necessary to connect two flue pipe sections, the drawbacks of this manual adjustment become even more prominent, making it difficult to achieve quick and accurate alignment of the two pipe ends, seriously affecting installation efficiency and connection quality.

[0004] Therefore, this utility model proposes a novel chimney flue fixing structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of cumbersome clamping and fixing operations, low reliability, and difficulty in achieving rapid centering and clamping in the existing flue pipe fixing structure, this utility model aims to provide a new fixing structure with improved structure that can achieve rapid synchronous clamping and precise positioning.

[0006] This utility model provides a novel fixing structure, including a housing and a fixing mechanism disposed within the housing;

[0007] The fixing mechanism includes a second fixing post fixedly connected inside the housing, a gear rotatably mounted on the second fixing post, two racks symmetrically arranged on both sides of the gear and meshing with it, two first clamping blocks fixedly connected to the two racks respectively, a handwheel coaxially fixedly connected to the gear, and a positioning pin inserted and detachably through the second fixing post and the gear.

[0008] Both racks are slidably connected to the outer casing. By rotating the handwheel to drive the gears, the two racks can move synchronously towards or away from each other, thereby causing the two first clamping blocks to simultaneously clamp or release the object. After clamping, the gears are locked and braked to the second fixing post by the positioning pin to prevent accidental loosening.

[0009] Preferably, the fixing mechanism further includes a first fixing post, which is fixedly connected between the second fixing post and the housing. The first fixing post provides reinforced support to the second fixing post that carries the gear, effectively improving the overall rigidity and structural stability of the fixing mechanism under clamping force and preventing deformation of key components.

[0010] Preferably, the outer casing has a groove for the handwheel to move. This groove exposes part of the handwheel's structure outside the casing, allowing operators to directly and conveniently rotate the handwheel without opening or disassembling the casing. This greatly simplifies installation and adjustment procedures and improves on-site construction efficiency.

[0011] Preferably, the novel fixing structure further includes a positioning mechanism fixedly connected to the outer shell. The positioning mechanism includes a first fixing block, a lead screw rotatably passing through the first fixing block, a second fixing block threadedly connected to the lead screw, and a second clamping block fixedly connected to the second fixing block. The addition of this positioning mechanism provides a dedicated structural basis for achieving the docking and adjustment of the two flue pipe sections.

[0012] Preferably, as a further optimization of the positioning mechanism, the positioning mechanism also includes a lever fixedly connected to one end of the lead screw. The operator can drive the lead screw to rotate by turning the lever, thereby achieving precise adjustment of the position of the second fixed block, providing an intuitive and labor-saving operation method.

[0013] Preferably, to ensure the smoothness of the positioning adjustment process, the positioning mechanism further includes a slider fixedly connected to the second fixed block, and a guide groove corresponding to the slider is provided on the first fixed block. The slider slides within the guide groove. This mating structure can effectively constrain the movement trajectory of the second fixed block, preventing unnecessary rotation or swaying under the drive of the lead screw, and ensuring the stability of the second clamping block's posture.

[0014] Preferably, to achieve synchronous alignment, the lead screw includes a left-hand threaded section and a right-hand threaded section with opposite directions of rotation, and there are two second fixing blocks, which are threadedly connected to the left-hand threaded section and the right-hand threaded section, respectively. When the lead screw rotates, the two second fixing blocks will move synchronously towards or away from each other along the axis of the lead screw, thereby driving the two second clamping blocks to quickly and synchronously align and clamp the two flue pipe sections.

[0015] Preferably, in a specific application scenario, the outer shell is used to be installed on a wall, while the first clamping block and the second clamping block are used to clamp the flue pipe, thereby concretizing the function of this utility model and making it a reliable tool specifically for flue pipe installation.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by setting a handwheel, a gear, and two symmetrical racks meshing with the gear, and making the racks drive the first clamping block to move, the problem of unstable clamping of flue pipe, uneven force, and cumbersome operation in the prior art is solved, and the technical effect of synchronous, centered, fast and firm clamping of flue pipe can be achieved in a single operation.

[0018] 2. In this utility model, by setting a hand lever, a lead screw with a threaded section of opposite direction, and two second fixing blocks respectively threaded to the opposite threaded section, the problems of difficulty in manual alignment, low accuracy, and low efficiency when connecting two flue pipe sections in the prior art are solved. The technical effect of synchronous, precise fine adjustment and rapid alignment of two flue pipe sections is achieved, which significantly improves the connection quality and installation efficiency.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Example:

[0027] Please refer to Figures 1 to 4 This utility model provides a novel fixing structure, which aims to solve the problems of unstable fixing and difficult docking and adjustment of the flue pipe 3 in the prior art.

[0028] like Figure 1 and Figure 2 As shown, the novel fixing structure includes a housing 101 and a fixing mechanism 1 disposed within the housing 101.

[0029] Specifically, the fixing mechanism 1 includes a second fixing post 108, which is fixedly connected to the inside of the housing 101; a gear 104 is rotatably mounted on the second fixing post 108; two racks 102 are symmetrically arranged on both sides of the gear 104, and both racks 102 are slidably connected to the housing 101, while each rack 102 meshes with the gear 104; two first clamping blocks 103 are respectively fixedly connected to the two racks 102; a handwheel 105 is coaxially fixedly connected to the gear 104 for driving the gear 104 to rotate; the fixing mechanism 1 also includes a positioning pin 106, on which the second fixing post 108 and the gear 104 are provided with mutually engaging pin holes, and the positioning pin 106 is insertably inserted into the pin hole.

[0030] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0031] As a preferred embodiment, in order to clarify the application scenario of the present invention, the outer shell 101 is used to be installed on the wall 4, and the two first clamping blocks 103 are used to clamp the flue pipe 3.

[0032] In a preferred embodiment, to further enhance the structural strength and stability of the fixing mechanism 1, the fixing mechanism 1 also includes a first fixing column 107; the first fixing column 107 is fixedly connected between the second fixing column 108 and the outer shell 101, and provides reinforced support to the second fixing column 108 that carries the gear 104.

[0033] As another preferred embodiment, in order to facilitate the operator to adjust the fixing mechanism 1, a groove is provided on the outer casing 101 for the handwheel 105 to move; the groove is provided so that part of the handwheel 105 is exposed outside the outer casing 101, and the operator can directly rotate the handwheel 105 without opening the outer casing 101.

[0034] Furthermore, this novel fixing structure also includes a positioning mechanism 2 fixedly connected to the outer casing 101, used for docking and adjusting the two flue pipes 3. Please refer to the following for details. Figure 3 and Figure 4 The positioning mechanism 2 includes a first fixing block 202, a lead screw 203 rotatably passing through the first fixing block 202, and a second fixing block 204 threadedly connected to the lead screw 203; a second clamping block 205 is fixedly connected to the second fixing block 204.

[0035] In the preferred design of the positioning mechanism 2, the lever 201 is fixedly connected to one end of the lead screw 203 to drive the lead screw 203 to rotate. To ensure that the second fixed block 204 moves smoothly in a linear manner, the positioning mechanism 2 also includes a slider 206 fixedly connected to the second fixed block 204. The first fixed block 202 is provided with a guide groove that cooperates with the slider 206, and the slider 206 is slidably installed inside the guide groove.

[0036] In another preferred design of the positioning mechanism 2, in order to achieve synchronous centering adjustment of the two flue pipes 3, the lead screw 203 specifically includes a left-hand threaded section and a right-hand threaded section with opposite directions of rotation; correspondingly, there are two second fixing blocks 204, which respectively cooperate with the left-hand threaded section and the right-hand threaded section through internal threads.

[0037] Working principle:

[0038] When it is necessary to fix the flue pipe 3, the operator turns the handwheel 105, which drives the coaxially connected gear 104 to rotate. The two racks 102 meshing with the gear 104 move synchronously in opposite directions. The two first clamping blocks 103 fixedly connected to the racks 102 clamp the flue pipe 3. After clamping, the positioning pin 106 is inserted into the pin hole on the second fixing post 108 that can cooperate with the gear 104 to lock the gear 104, thereby ensuring the long-term reliability of clamping.

[0039] When two flue pipes 3 need to be connected, the operator rotates the lever 201, which drives the lead screw 203 to rotate. Since the lead screw 203 has a left-hand threaded section and a right-hand threaded section with opposite directions of rotation, the two second fixing blocks 204, which are threaded onto it respectively, move synchronously towards or away from each other. During this process, the sliding cooperation of the slider 206 in the guide groove ensures that the second fixing block 204 only moves in a straight line and does not rotate. The second clamping block 205 fixed on the second fixing block 204 drives the two flue pipes 3 to achieve precise alignment, solving the problem of difficult connection and adjustment.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
