Description

Technical Field

[0001] This utility model relates to the field of hardware technology, specifically to a fixing base. Background Technology

[0002] In many technical fields such as mechanical installation, pipeline laying, and equipment fixing, it is often necessary to use special fixing brackets to position and install components such as columnar parts and pipes to ensure the stability and positional accuracy of the components during use.

[0003] In the prior art, Chinese utility model patent with patent authorization announcement number CN 207892072 U discloses an anti-seismic single-tube base, and refers to... Figure 1 As shown.

[0004] The base includes a base plate and a tubular sleeve. The base plate is used for fixed connection to a fixed surface, while the sleeve is used to fit and connect cylindrical or tubular components. Through the tight fit between the base plate and the fixed surface, and the sleeve's containment and positioning of the components, initial fixation of the cylindrical or tubular components is achieved. This existing technical solution has a simple structure and is easy to install, meeting the foundation's fixing requirements to a certain extent, and has particular application value in seismic scenarios.

[0005] However, if the existing fixing seat only uses its own tubular structure to wrap and limit the cylindrical or tubular parts without setting a positioning and locking structure for the axial and circumferential directions of the parts, it is easy to cause the cylindrical or tubular parts connected in the sleeve to move axially or rotate circumferentially. Utility Model Content

[0006] In view of the problems pointed out in the background art, the present invention proposes a fixing base to solve the above-mentioned technical problems.

[0007] The technical solution of this utility model is implemented as follows: A fixing base includes a connecting sleeve, the lower end of which is connected to a base. The connecting sleeve is a U-shaped structure with an opening on one side. Connecting grooves are provided on three sides of the connecting sleeve, and the connecting grooves are arranged in the vertical direction. A bolt is connected in the connecting groove, and a nut is connected to the bolt. The nut is located on the outside of the connecting sleeve, and the head of the bolt is located on the inside of the connecting sleeve.

[0008] The present invention is further configured such that the connecting groove extends downward to the base, and the base is provided with an insertion hole corresponding to and communicating with the connecting groove. The diameter of the insertion hole is larger than the width of the connecting groove, so that the head of the bolt can be inserted through the insertion hole and the bolt shank can enter the connecting groove.

[0009] The present invention is further configured such that the outer diameter of the nut is larger than the diameter of the insertion hole.

[0010] The present invention is further provided that the base is provided with a fixing hole, and the insertion hole can be used as a fixing hole.

[0011] The present invention is further configured such that the head of the bolt is a cylindrical structure.

[0012] The present invention is further provided with a reinforcing rib connecting the connecting sleeve and the base.

[0013] The present invention is further provided that the base is provided with a slot corresponding to the lower opening of the connecting sleeve.

[0014] The present invention is further configured such that the diameter of the bolt shank is equal to or less than the width of the connecting groove.

[0015] The present invention is further configured such that the base and the connecting sleeve are integrally formed.

[0016] The present invention is further provided that a washer is connected to the bolt.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows: The fixing base provided by this utility model has a cylindrical component inserted into the connecting sleeve during use. The outer side of the cylindrical component is provided with a T-shaped groove structure that corresponds to the screw head of the bolt. After tightening the nut, the cylindrical component and the connecting sleeve are fixedly connected by the cooperation of the bolt and the T-shaped groove, which prevents the cylindrical component from axial movement and circumferential rotation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] For reference as follows Figures 1-6 The present invention will be described as follows: Example: A fixing base includes a connecting sleeve 1, which is a component that directly supports a cylindrical part. The lower end of the connecting sleeve 1 is connected to a base 2. The connecting sleeve 1 is a U-shaped structure with an opening on one side. The connecting sleeve 1 forms a surrounding limit on the cylindrical part through three closed sides, providing a stable mounting reference surface for the cylindrical part.

[0028] The connecting sleeve 1 has connecting grooves 3 on its three sides (the width of the connecting grooves 3 matches the diameter of the bolt 4's thread, ensuring that the bolt 4 can be smoothly adjusted along the length of the connecting grooves 3). The connecting grooves 3 are arranged vertically, and the bolt 4 is connected to the connecting grooves 3. A nut 5 is connected to the bolt 4, with the nut 5 located on the outside of the connecting sleeve 1 and the head of the bolt 4 located on the inside of the connecting sleeve 1. The threaded portion passes through the connecting grooves 3, with its head located on the inside of the connecting sleeve 1. The nut 5 is threaded onto the end of the threaded portion that extends beyond the outside of the connecting sleeve 1. This assembly structure allows the bolt 4 to move vertically through the connecting grooves 3, flexibly adapting to the fixing requirements of different height positions.

[0029] In use, first adjust the up-down position of the bolts 4 on each side along the connecting groove 3 according to the position of the T-slot on the cylindrical component, so that the head of the bolt 4 corresponds to the T-slot of the cylindrical component; then insert the cylindrical component into the sleeve from the top end of the connecting sleeve 1, ensuring that the T-slot on the outer side of the cylindrical component is accurately aligned with the head of the bolt 4. At this time, the head of the bolt 4 is embedded in the T-slot, forming a preliminary mechanical limit. After that, tighten the nut 5 on the outside of the connecting sleeve 1. The nut 5 is in contact with the outer side of the connecting sleeve 1 and generates a clamping force. This pressure is transmitted to the bolt head on the inside through the screw, so that the bolt head is pressed tightly against the groove wall of the T-slot.

[0030] When nut 5 is tightened, the bolt head fits tightly against the wall of the T-slot, generating a locking force that directly restricts the movement of the cylindrical component along its length, completely preventing axial movement and circumferential rotation. At the same time, the bolts 4 on the three sides are inserted into the T-slots of the cylindrical component from different directions. The bolt head and the longitudinal wall of the T-slot form a circumferential limit. Through the friction of the contact surface and the mechanical blocking effect, the rotation of the cylindrical component around its own axis is restricted, effectively preventing circumferential displacement.

[0031] The base 2 is connected to the lower end of the connecting sleeve 1. Its function is to provide a stable installation foundation for the entire fixed seat. When in use, the base 2 can be connected to the ground, frame and other fixed surfaces by fasteners such as anchor bolts, so that the connecting sleeve 1 remains vertical. This ensures that the column is in the preset fixed position after installation, and avoids the overall fixing effect being affected by the shaking of the base 2.

[0032] The connecting groove 3 extends downwards to the base 2. The base 2 has an insertion hole 6 that corresponds to and communicates with the connecting groove 3. The diameter of the insertion hole 6 is larger than the width of the connecting groove 3 (to provide a channel for the assembly of the bolt 4). The head of the bolt 4 can pass through the insertion hole 6, allowing the bolt 4's thread to enter the connecting groove 3. By adopting the above technical solution, it is convenient to insert the bolt 4 into the connecting groove 3, so that when the bolt 4 and nut 5 are in the connected state, the bolt 4 can be inserted into the connecting groove 3 through the insertion hole 6.

[0033] When bolt 4 is pre-connected to nut 5 (not fully tightened), the assembly of bolt 4 and connecting sleeve 1 can be completed without disassembling nut 5. The bolt head is inserted from the upper side of the base through the insertion hole 6, so that the screw enters the connecting groove 3.

[0034] The outer diameter of nut 5 is larger than the diameter of insertion hole 6. This size limitation effectively prevents bolt 4 from coming out of insertion hole 6 during assembly or use.

[0035] The base 2 is provided with a fixing hole 7, which is used to connect the entire fixing base to the ground, frame and other fixed surfaces (such as by passing an anchor bolt through the fixing hole 7 and locking it).

[0036] The insertion hole 6 can also be used as a fixing hole 7. In addition to serving as an assembly channel for bolt 4, the insertion hole 6 also functions as a fixing hole 7, meaning that the insertion hole 6 is a "one hole, two uses" structure.

[0037] The head of bolt 4 is cylindrical. Its diameter is matched with the diameter of insertion hole 6 and is smaller than the diameter of insertion hole 6, ensuring that the head of bolt 4 can be smoothly inserted into insertion hole 6 from the upper side of base 2.

[0038] The head of bolt 4 slides into the T-slot on the cylindrical part, preventing the head of bolt 4 from coming out of the T-slot.

[0039] The base 2 has a slot 9 that corresponds to the lower opening of the connecting sleeve 1.

[0040] The diameter of the bolt 4's thread is equal to or less than the width of the connecting groove 3. This allows the bolt 4's thread to slide freely up and down along the connecting groove 3 after entering it, while the groove wall of the connecting groove 3 provides lateral restraint for the thread, preventing it from shifting.

[0041] The connecting sleeve 1 and the base 2 are manufactured using an integral molding process (integrated installation), ensuring the structural integrity and basic strength of their connection. Furthermore, a reinforcing rib 8 with a triangular cross-section is provided between the outer wall of the connecting sleeve 1 and the upper surface of the base 2. The reinforcing rib 8 is fixedly connected to the side wall of the connecting sleeve 1 and the upper surface of the base 2 (integrated molding), forming a support structure for the connecting sleeve 1. When the connecting sleeve 1 bears the cylindrical component, it is subjected to radial pressure and axial force transmitted by the cylindrical component. The reinforcing rib 8 can disperse this force, preventing structural deformation or fracture due to stress concentration at the connection between the connecting sleeve 1 and the base 2. This significantly improves the connection strength and overall structural rigidity of the connecting sleeve 1 and the base 2, and extends the service life of the fixing seat.

[0042] A washer is attached to bolt 4. It is fitted onto the outside of the screw and located between the outer surface of nut 5 and connecting sleeve 1.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
