Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction tools technology, and in particular to a construction trowel. Background Technology
[0002] Plastering is a crucial step in building construction, aiming to achieve a smooth and even finish on walls or floors. Because the shape, structure, and construction requirements of walls and floors vary, different shaped plastering slabs are often used in practice. For example, when dealing with inside and outside corners, door and window edges, or walls with special shapes, specialized plastering slabs are required to ensure the smoothness and aesthetics of the plastering.
[0003] However, existing trowels usually adopt an integrated structure design. Since the trowel plate and handle are not detachable, when it is necessary to change to different shapes of trowel plates for different construction areas, construction workers have to carry multiple trowels of different specifications. This not only increases construction costs, but also brings great inconvenience to the construction workers in terms of carrying and management. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes a construction trowel, which has a trowel plate and a handle that are easy to separate, thereby facilitating the replacement of trowel plates of different shapes.
[0005] This utility model provides a construction trowel, including a trowel plate and a handle. The top of the trowel plate is provided with a connecting strip plate, and the top of the connecting strip plate is provided with multiple limiting grooves. The bottom of the handle is provided with a support cylinder, and the bottom of the support cylinder is provided with a connecting block. The connecting block is sleeved on the connecting strip plate and can slide along the length of the connecting strip plate. The support cylinder is provided with a locking device inside.
[0006] The locking component includes a sliding column, a limiting rod at the bottom of the sliding column, a compression spring sleeved on the outside of the limiting rod, a movable connecting block at the bottom of the limiting rod inserted into the inside of the limiting groove, a locking hole on the side wall of the support cylinder, and a locking rod extending from the sliding column through the locking hole to the outside of the support cylinder.
[0007] By adopting the above technical solution, a matching connecting strip and connecting block are set between the tool holder and the mud-plastering plate, making the mud-plastering plate easy to disassemble and install. This allows for the quick replacement of mud-plastering plates of different shapes according to construction needs, thus improving applicability.
[0008] Preferably, the locking hole includes a long vertical part, a turning part, and a short vertical part, and when the locking rod is engaged in the short vertical part, the compression spring is in a compressed state.
[0009] Using the above technical solution, the card hole consists of a long vertical part, a turning part and a short vertical part. The card hole is designed in the shape of "J". When the card rod is locked in the short vertical part, the limiting rod will be locked in the limiting groove.
[0010] Preferably, both the sliding column and the limiting rod are cylindrical, and the sliding column can slide up and down or rotate within the support cylinder.
[0011] Using the above technical solution, when the lever is pulled down to the turning part, it will cause the sliding column to move down and rotate. When the lever moves to the long vertical part, under the action of the spring force of the compression spring, it will cause the sliding column and the limit rod to move up, thereby realizing unlocking.
[0012] Preferably, the compression spring is disposed between the bottom wall of the sliding column and the top wall of the connecting block, and the diameter of the sliding column is larger than the diameter of the limiting rod.
[0013] Preferably, the limiting rod inserted into the limiting groove has a gap with the bottom wall of the limiting groove, and the length of the gap matches the length of the short vertical part.
[0014] By adopting the above technical solution, the gap setting allows the limiting rod to have room to move downward when the locking rod moves to the turning part.
[0015] Preferably, the cross-section of the connecting strip is I-shaped, and the bottom of the connecting block is provided with a T-shaped groove.
[0016] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: by setting a matching connecting strip and connecting block between the handle and the mud-plastering plate, the mud-plastering plate can be easily disassembled and installed, thereby allowing for quick replacement of mud-plastering plates of different shapes according to construction needs and improving applicability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] like Figure 1-3 As shown, the present invention proposes a construction trowel, which includes a trowel plate 1 and a handle 5. The top of the trowel plate 1 is provided with a connecting strip plate 2, and the top of the connecting strip plate 2 is provided with multiple limiting grooves 21. The bottom of the handle 5 is provided with a support cylinder 4, and the bottom of the support cylinder 4 is provided with a connecting block 3. The connecting block 3 is sleeved on the connecting strip plate 2 and can slide along the length direction of the connecting strip plate 2. The support cylinder 4 is provided with a locking device inside.
[0025] Among them, the cross-section of the connecting strip 2 is "I" shaped, and the bottom of the connecting block 3 is provided with a "T" shaped groove.
[0026] It should be noted that the "I"-shaped connecting strip 2 enables the connecting block 3, which is sleeved on the connecting strip 2, to have a longitudinal limiting effect, while it can slide and move out along the length direction, thus completing the separation of the connecting block 3 from the connecting strip 2.
[0027] The clamping component includes a sliding column 6, a limiting rod 8 at the bottom of the sliding column 6, a compression spring 9 sleeved on the outside of the limiting rod 8, a movable through connecting block 3 at the bottom of the limiting rod 8 inserted into the inside of the limiting groove 21, a locking hole 41 on the side wall of the support cylinder 4, and a locking rod 7 extending from the movable through locking hole 41 to the outside of the support cylinder 4 on the side wall of the sliding column 6.
[0028] It should be noted that the design of multiple limiting grooves 21 can also adjust the installation position of the handle 5, improving adaptability.
[0029] By adopting the above technical solution, by setting a matching connecting strip 2 and connecting block 3 between the tool holder and the mud-plastering plate 1, the mud-plastering plate 1 can be easily disassembled and installed, thereby allowing for quick replacement of mud-plastering plates 1 of different shapes according to construction needs, thus improving applicability.
[0030] In this embodiment, the locking hole 41 includes a long vertical part, a turning part and a short vertical part. When the locking rod 7 is engaged in the short vertical part, the compression spring 9 is in a compressed state. The compression spring 9 is disposed between the bottom wall of the sliding column 6 and the top wall of the connecting block 3. The diameter of the sliding column 6 is larger than the diameter of the limiting rod 8.
[0031] The design of the locking hole 41, which consists of a long vertical part, a turning part, and a short vertical part, makes the locking hole 41 "J" shaped. When the locking rod 7 is locked in the short vertical part, the limiting rod 8 will be locked in the limiting groove 21, thereby limiting the sliding between the connecting block 3 and the connecting strip 2.
[0032] Please see Figure 2 In this embodiment, both the sliding column 6 and the limiting rod 8 are cylindrical, and the sliding column 6 can slide up and down or rotate within the support cylinder 4.
[0033] It should be noted that when the lever 7 is pulled down to the turning part, it will cause the sliding column 6 to move down and rotate. When the lever 7 moves to the long vertical part, under the action of the spring force of the compression spring 9, it will push the sliding column 6 up, thereby moving the lever 7 to the top of the long vertical part, so that the limiting rod 8 can be moved out of the limiting groove 21, thereby unlocking.
[0034] In this embodiment, the limiting rod 8 inserted into the limiting groove 21 has a gap with the bottom wall of the limiting groove 21, and the length of the gap matches the length of the short vertical part. By setting the gap, the limiting rod 8 has room to move downward when the locking rod 7 moves to the turning part.
[0035] Working principle: The connecting block 3 is fitted onto the connecting strip 2 at the top of the mud-touching plate 1. At this time, the "T" groove at the bottom of the connecting block 3 matches the "I" shaped section of the connecting strip 2, allowing the connecting block 3 to slide along the length of the connecting strip 2, thus achieving a longitudinal limiting effect. Then, the locking rod 7 is moved from the long vertical part in the locking hole 41 to the short vertical part, which puts the compression spring 9 into a compressed state. At this time, the locking rod 7 is engaged in the locking hole 41, and the limiting rod 8 is inserted into the corresponding limiting groove 21, thus achieving a lateral limiting effect and realizing the installation between the mud-touching plate 1 and the handle 5.
[0036] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
