Description

Technical Field

[0001] This utility model relates to the field of electromechanical construction technology, and in particular to an electromechanical construction sleeve pre-embedding device. Background Technology

[0002] In electromechanical construction, pre-embedded pipe sleeves are pipe fittings pre-installed during the building structure construction phase. They are mainly used to provide channels for the subsequent laying of electromechanical pipelines (such as water supply, drainage, fire protection, electrical, and ventilation pipelines). Their core functions encompass structural protection, functional assurance, and construction convenience. They can also prevent mechanical damage during pouring and vibration, or the squeezing and damage to the pipes caused by subsequent structural settlement.

[0003] For example, CN215009380U discloses a pre-embedded device for electromechanical construction sleeves, including a main body. The main body has a first movable plate, a second movable plate and a third movable plate inside. The top of the second movable plate has several first through holes. The inside of the first through holes is a movable rod. The top and bottom of the movable rod are respectively welded with a push block and a spring. The bottom of the spring is fixedly connected to the third movable plate. The top of the first movable plate and the bottom of the third movable plate are respectively rotatably connected with a first threaded rod and a third threaded rod. The top and bottom of the main body are both provided with threaded through holes.

[0004] However, in the existing technology, most sleeve locking devices can only position a single sleeve, or require multiple sets of independent structures to lock multiple sleeves separately, resulting in cumbersome operation and low efficiency. In addition, some locking devices use a fixed-size clamping structure, which requires replacing the entire set of clamps or making cumbersome parameter adjustments when dealing with sleeves of different diameters, or even being unable to adapt. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that most existing sleeve locking devices can only position a single sleeve, or require multiple sets of independent structures to lock multiple sleeves separately, resulting in cumbersome operation and low efficiency. Therefore, this utility model proposes an electromechanical construction sleeve pre-embedding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electromechanical construction sleeve pre-embedded device, including an installation hole fixedly connected to one side of the machine of the installation plate, multiple installation holes opened on the side wall of the side plate, a track fixedly connected to the top of the side wall of the installation plate, a first support block fixedly connected to the side wall of the track, and a positioning mechanism installed on one side of the installation plate.

[0007] The positioning mechanism includes a lifting block. Two connecting frames are symmetrically fixedly connected to the bottom of the lifting block. A first movable frame is rotatably connected to the outside of one connecting frame, and a second movable frame is rotatably connected to the outside of the other connecting frame. A limit plate is fixedly connected to one end of the second movable frame. The bottom end of the limit plate abuts against the top of the first movable frame. Abutting blocks are rotatably connected to the bottom ends of both the second and first movable frames. A baffle is abutting against the bottom end of the abutting block. A movable rod is fixedly connected to the bottom of the baffle. A pressing block is fixedly connected to the bottom of the movable rod.

[0008] Preferably, a second support block is fixedly connected to the side wall of the mounting plate, and an intermediate plate is fixedly connected to the center of the side wall of the mounting plate.

[0009] Preferably, the inner side of the first support block is threaded with a threaded rod, and the bottom end of the threaded rod is rotatably connected to the top of the lifting block.

[0010] Preferably, the side wall of the mounting plate is fixedly connected to a track, and the lifting block is slidably connected to the track.

[0011] Preferably, a spring is provided between the baffle and the intermediate plate, and the spring is sleeved on the outer surface of the movable rod.

[0012] Preferably, the bottom end of the movable rod passes through the intermediate plate, and a sliding rod is fixedly connected to one side of the top of the extrusion block.

[0013] Preferably, the slide bar is slidably connected to the intermediate plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the rotation of the threaded rod drives the lifting block to move longitudinally, thereby realizing the linkage and downward movement of the first and second movable frames. During the lifting process, the limiting plate and the first movable frame form a mechanical constraint to ensure that the path is controlled and synchronous coordination is achieved. The bottom abutment block applies downward pressure after contacting the baffle, and at the same time pushes the connected movable rod to move downward. The movable rod then drives the squeezing block and the support block to cooperate to complete the stable positioning of the construction sleeve. It has the ability to lock multiple sleeves at the same time, which improves the adaptability and construction efficiency of the equipment. The top of the movable rod is equipped with a spring, which can realize the automatic reset function. This design enhances the structural flexibility and is suitable for construction sleeves of different specifications. The two movable frames cooperate under the limit guidance and form an effective linkage under the action of force, thereby ensuring the efficiency and stability of the sleeve positioning process.

[0016] 2. In this utility model, the lifting block is driven by a threaded rod to move stably up and down along the track, ensuring no deviation or shaking during the movement. This drives the first and second movable frames to rise and fall synchronously. The lower end abutment block pushes the movable rod to move axially, and the movable rod transmits the pressing force downward to the extrusion block, achieving precise extrusion and positioning of the sleeve. To prevent the extrusion block from tilting or deviating during operation, the system is equipped with a sliding rod that is linked to it. The sliding rod provides guidance and limit control to ensure that the extrusion block moves along a precise path. The entire structural design emphasizes the stability and synchronization of movement, improving the working efficiency and positioning accuracy of the device, and ensuring the structural reliability and control consistency during operation.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-4As shown, this utility model provides an electromechanical construction sleeve pre-embedded device, including an installation plate 1 with a fixed installation hole 3 on one side of the machine, a side plate 2 with multiple installation holes 3 on the side wall, a track 12 fixedly connected to the top of the side wall of the installation plate 1, a first support block 11 fixedly connected to the side wall of the track 12, and a positioning mechanism 4 installed on one side of the installation plate 1.

[0025] The positioning mechanism 4 includes a lifting block 42. Two connecting frames 421 are symmetrically fixedly connected to the bottom of the lifting block 42. A first movable frame 43 is rotatably connected to the outside of one connecting frame 421, and a second movable frame 44 is rotatably connected to the outside of the other connecting frame 421. A limit plate 441 is fixedly connected to one end of the second movable frame 44. The bottom end of the limit plate 441 abuts against the top of the first movable frame 43. Abutting blocks 45 are rotatably connected to the bottom ends of both the second movable frame 44 and the first movable frame 43. A baffle 471 is abutted against the bottom end of the abutting block 45. A movable rod 47 is fixedly connected to the bottom of the baffle 471. A pressing block 46 is fixedly connected to the bottom of the movable rod 47.

[0026] The specific settings and functions of this embodiment are described below. In this structure, the longitudinal displacement of the lifting block 42 is achieved through the rotational drive of the threaded rod 41. When the threaded rod 41 rotates clockwise or counterclockwise, relying on the characteristics of its helical transmission mechanism, the rotational motion can be effectively converted into the linear downward movement of the lifting block 42. During this process, the lifting block 42 is linked to the first movable frame 43 and the second movable frame 44, that is, the downward movement of the lifting block 42 will synchronously drive the first movable frame 43 and the second movable frame 44 to move downward as a whole.

[0027] During the linkage process, the limiting plate 441 at one end of the second movable frame 44 plays a key limiting and control role. The limiting plate 441 forms an effective mechanical constraint relationship with the first movable frame 43, guiding and restricting the movement path of the first movable frame 43 during downward movement. This structural design ensures coordinated movement between the first movable frame 43 and the second movable frame 44, thereby guaranteeing reliable force synchronization when the abutment block 45 connected at their bottom contacts the baffle 471 and applies downward pressure to it.

[0028] While the abutment block 45 applies force to the baffle 471, it pushes the movable rod 47 connected to it downward. The downward pressing action of the movable rod 47 further drives the pressing block 46 located at one end to cooperate with the second support block 14, thereby achieving stable positioning of the construction sleeve. This structure can lock multiple sleeves simultaneously, has good adaptability and reusability, and effectively improves construction efficiency and equipment versatility.

[0029] Furthermore, the movable rod 47 is designed to move vertically, and its top is equipped with a spring 49, which allows the mechanism to automatically reset through elastic recovery after force is applied. The spring 49 not only enhances the flexibility of the structure but also ensures that the first movable frame 43 and the second movable frame 44 can move in coordination under the guidance of the limiting plate 441 during the positioning of sleeves with different outer diameters. This linkage mechanism allows the two movable frames to interact under force, adapting to different specifications of construction sleeves, thereby achieving efficient locking and stable fixation of the sleeve.

[0030] Example 2: Figures 2-4 As shown, a second support block 14 is fixedly connected to the side wall of the mounting plate 1, and an intermediate plate 13 is fixedly connected to the center of the side wall of the mounting plate 1. A threaded rod 41 is threadedly connected to the inner side of the first support block 11, and the bottom end of the threaded rod 41 is rotatably connected to the top of the lifting block 42. A track 12 is fixedly connected to the side wall of the mounting plate 1, and the lifting block 42 is slidably connected to the track 12. A spring 49 is provided between the baffle 471 and the intermediate plate 13, and the spring 49 is sleeved on the outer surface of the movable rod 47. The bottom end of the movable rod 47 passes through the intermediate plate 13, and a sliding rod 48 is fixedly connected to one side of the top of the pressing block 46. The sliding rod 48 is slidably connected to the intermediate plate 13.

[0031] The overall effect of this embodiment is that when the lifting block 42 is driven by the threaded rod 41 and subjected to axial pushing force, it moves stably up and down in a set direction within the track 12. This structural design ensures that the lifting block 42 does not deviate or sway during movement, thereby stably and synchronously driving the first movable frame 43 and the second movable frame 44 connected to it to perform an overall lifting movement. During this process, the first movable frame 43 and the second movable frame 44, through the abutment block 45 set at the lower end, cooperate to push the movable rod 47 downward along the axial direction.

[0032] As the movable rod 47 moves downward, the pressing block 46 located below it is subjected to the clamping force from the movable rod 47, thus moving downward in the same direction to effectively press and position the sleeve at the preset position. To prevent the pressing block 46 from tilting, rotating, or shifting during the positioning process, a sliding rod 48 is further provided in the system, and through structural linkage, it participates in the movement along with the pressing block 46. The sliding rod 48 not only provides effective guidance for the movement trajectory of the pressing block 46, but also realizes the limit control of its displacement, ensuring that it is always pressed in a controlled manner along a precise path, thereby significantly improving the working stability and positioning accuracy of the entire device.

[0033] The device's operation and working principle are as follows: When the threaded rod 41 rotates, it pushes the lifting block 42 downwards. During this process, the lifting block 42 simultaneously drives the first movable frame 43 and the second movable frame 44 downwards. At this time, the second movable frame 44 constrains the movement trajectory of the first movable frame 43 through the limiting plate 441 at one end. When the abutment block 45 at the bottom of the first movable frame 43 and the second movable frame 44 applies force to the baffle 471, it not only pushes the movable rod 47 downwards but also allows the pressing block 46 to cooperate with the second support block 14 to position the construction sleeve, achieving synchronous locking of multiple sleeves.

[0034] Furthermore, the movable rod 47 can move flexibly under the elastic action of the spring 49. When positioning multiple sleeves, the first movable frame 43 and the second movable frame 44 move in concert due to the constraint of the limiting plate 441, and adjust adaptively through interaction force, thereby achieving locking of sleeves of different sizes.

[0035] When the lifting block 42 is pushed by the threaded rod 41, it will move steadily downward in a straight line within the track 12, ensuring smooth synchronous movement of the first movable frame 43 and the second movable frame 44. When the two movable frames push the movable rod 47 downward through the abutment block 45, the pressing block 46 is simultaneously subjected to a downward force to press the sleeve, while driving the slide rod 48 to move. Through the guiding and limiting function of the slide rod 48, the pressing block 46 is prevented from tilting during positioning.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
