Description

Technical Field

[0001] This utility model relates to the field of vibratory trowel technology, specifically to a vibratory trowel for waterproof mortar construction. Background Technology

[0002] In the construction of waterproof mortar, trowels are commonly used tools to evenly spread and compact the mortar. Traditional trowels rely on manual pressing and pushing, resulting in low construction efficiency and difficulty in ensuring mortar density, which can easily lead to problems such as hollowing and cracking of the waterproof layer. For example, Chinese patent document CN223061960U discloses a trowel with an adjustable angle cutter head structure. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a vibratory trowel for waterproof mortar construction to solve the problems mentioned in the background section above.

[0004] This utility model is achieved through the following technical solution:

[0005] A vibratory trowel for waterproof mortar application includes a trowel blade and a handle. The trowel blade has a vibration mechanism located on the back of the handle near the handle. The vibration mechanism drives the trowel to vibrate. The trowel blade and the handle are connected by a vibration isolation device, which includes a spring to reduce the vibration amplitude transmitted from the vibration mechanism to the handle.

[0006] Furthermore, the handle includes several spaced vertical tubes and a horizontal tube connecting the vertical tubes. The vertical tubes and the trowel blade are spaced apart and form a vibration space. The vibration isolation device also includes a connecting ball fixedly connected to the vertical tube and a sleeve rotatably connected to the connecting ball. The spring is sleeved on the outer periphery of the sleeve. The trowel blade passes through the sleeve from bottom to top and is engaged with the trowel blade.

[0007] Furthermore, the vibration isolation device also includes a horizontal plate fixedly connected to the vertical pipe, a connecting ball fixedly connected to the horizontal plate, an upper end of the spring abutting against the horizontal plate, and a lower end of the spring abutting against the trowel blade.

[0008] Furthermore, the distance between the trowel blade and the vertical tube is equal to the distance between the sleeve and the horizontal plate.

[0009] Furthermore, the outer surface of the horizontal tube is provided with anti-slip texture.

[0010] Furthermore, the vibration mechanism is a vibration motor or a miniature vibration motor.

[0011] The beneficial effects of this utility model are as follows: A vibratory trowel for waterproof mortar construction includes a trowel blade and a handle. A vibration mechanism is provided on the back of the trowel blade near the handle, which drives the trowel to vibrate. The trowel blade and the handle are connected by a vibration isolation device, which includes a spring to reduce the vibration amplitude transmitted from the vibration mechanism to the handle. The vibration mechanism drives the trowel blade to generate high-frequency vibration, thereby assisting in mortar laying and compaction, improving construction efficiency. Furthermore, during vibration, the spring connects the trowel blade and the handle, reducing or preventing the transmission of vibration force from the trowel blade to the handle, avoiding hand fatigue during prolonged use, and preventing issues such as reduced operational accuracy and comfort. By reducing vibration transmission, construction quality is improved. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Reference Figures 1 to 4As shown, a vibratory trowel for waterproof mortar construction includes a trowel blade 1 and a handle 2. The trowel blade 1 is provided with a vibration mechanism 3 near the back of the handle 2. The vibration mechanism 3 is used to drive the trowel to vibrate. The trowel blade 1 and the handle 2 are connected by a vibration isolation device 4. The vibration isolation device 4 includes a spring 41, which is used to reduce the vibration amplitude transmitted from the vibration mechanism 3 to the handle 2.

[0020] The trowel blade 1 is driven by the vibration mechanism 3 to generate high-frequency vibration, thereby assisting in mortar laying and compaction, improving construction efficiency. During the vibration process, the trowel blade 1 is connected to the handle 2 by the spring 41, reducing or avoiding the transmission of vibration force from the trowel blade 1 to the handle 2. This avoids problems such as hand fatigue of construction workers due to prolonged use, affecting operating accuracy and comfort, and improves construction quality by reducing vibration transmission.

[0021] Reference Figure 2 and Figure 3 As shown, the handle 2 includes several vertical tubes 21 arranged at intervals, and horizontal tubes 22 connecting the vertical tubes 21. The vertical tubes 21 and the trowel blade 1 are arranged at intervals to form a vibration space 5. The vibration isolation device 4 also includes a connecting ball 42 fixedly connected to the vertical tubes 21, and a sleeve 43 rotatably connected to the connecting ball 42. The spring 41 is sleeved on the outer periphery of the sleeve 43. The trowel blade 1 is inserted through the sleeve 43 from bottom to top and is engaged with the trowel blade 1.

[0022] Through the rotatable connection between the sleeve 43 and the connecting ball 42, the trowel blade 1 can swing and move up and down around the connecting ball 42 to a certain extent during the vibration process of the vibration mechanism 3 driving the trowel blade 1 to vibrate. The vertical pipe 21 and the trowel blade 1 are arranged at intervals to form a vibration space 5, thereby increasing the vibration amplitude of the trowel blade 1 and better assisting in mortar laying and compaction.

[0023] Specifically, the upper end of the sleeve 43 is an arc-shaped constricted structure adapted to the connecting ball 42. During assembly, the connecting ball 42 is passed from bottom to top into the sleeve 43 and is snapped in place by the arc-shaped constricted structure.

[0024] The sleeve 43 includes a straight tube section 431 and a flat plate section 432. The straight tube section 431 and the flat plate section 432 are connected by screw fastening. The flat plate section 432 is embedded in the lower end of the trowel blade 1 and is flush with the lower end of the trowel blade 1 to prevent cement mortar from entering the straight tube section 431.

[0025] If cement mortar accidentally enters the connection between the straight pipe section 431 and the connecting ball 42 from the upper end, it can be disassembled and cleaned after the vibrating trowel is used to prevent the hardened mortar from affecting the rotation of the connecting ball 42 and the sleeve 43.

[0026] The outer periphery of the vertical pipe 21 is fitted with a protective sleeve 6, the lower end of which abuts against the trowel blade 1. The protective sleeve 6 is used to further prevent cement mortar from entering the vibration isolation device 4.

[0027] Reference Figure 2 and Figure 3 As shown, the vibration isolation device 4 also includes a horizontal plate 44 fixedly connected to the vertical pipe 21, a connecting ball 42 fixedly connected to the horizontal plate 44, an upper end of the spring 41 abutting against the horizontal plate 44, and a lower end of the spring 41 abutting against the trowel blade 1.

[0028] The spring 41 acts as a buffer and shock absorber between the horizontal plate 44 and the trowel blade 1. The vertical tube 21 and the sleeve 43 limit the movement distance of the spring 41 on both sides, ensuring that the spring 41 always stays in the correct force position during operation, and preventing the spring 41 from losing its shock absorption effect due to excessive offset or deformation.

[0029] Specifically, the horizontal plate 44 and the connecting ball 42 are connected by the first screw 45, and the horizontal plate 44 and the vertical tube 21 are connected by the second screw 46.

[0030] During assembly, the connecting ball 42 is inserted into the sleeve 43 from bottom to top, and the sleeve 43 is inserted into the trowel blade 1 from bottom to top. The spring 41 is sleeved on the outer circumference of the sleeve 43. Then, the first screw 45 passes through the horizontal plate 44 and is threadedly connected to the connecting ball 42. After all the sleeves 43 and the trowel blade 1 are assembled according to the above steps, the horizontal plate 44 is inserted into the vertical tube 21. Then, the second screw 46 passes through the vertical tube 21 and is threadedly connected to the horizontal plate 44 to complete the assembly.

[0031] Reference Figure 4 As shown, the distance between the trowel blade 1 and the vertical tube 21 is equal to the distance between the sleeve 43 and the horizontal plate 44. The contact surface between the trowel blade 1 and the vertical tube 21 is a plane, and the contact surface between the sleeve 43 and the horizontal plate 44 is also a plane.

[0032] Reference Figure 4 As shown, when the user needs to flatten the mortar, pressure can be applied to overcome the elasticity of the spring 41, causing the trowel blade 1 to abut against the vertical pipe 21 and the sleeve 43 to abut against the horizontal plate 44. This mutual abutment prevents lateral displacement between the handle 2 and the trowel blade 1. By limiting lateral displacement, the stability of the trowel blade 1 during mortar flattening is ensured, avoiding unevenness of the construction surface caused by relative movement between the handle 2 and the trowel blade 1, thus significantly improving construction quality.

[0033] The outer surface of the horizontal tube 22 is provided with anti-slip texture. The anti-slip texture can significantly increase the friction between the handle 2 and the operator's hand, effectively preventing the hand from slipping and ensuring that the operator can firmly grip the handle 2.

[0034] The vibration mechanism 3 is a vibration motor or a miniature vibration motor. Both miniature and vibration motors are existing vibration devices and will not be described in detail here. The vibration motor or miniature vibration motor is easy to install on the back of the trowel blade 1, and a protective cover is provided on the outside of the vibration mechanism 3. The protective cover can effectively prevent cement mortar from entering the interior of the vibration mechanism 3, avoiding blockage or damage to the mechanical parts of the vibration motor or miniature vibration motor after the mortar hardens, thereby ensuring the normal operation and service life of the vibration mechanism 3.

[0035] Furthermore, the power supply, control switch, and other structures used to drive the vibration mechanism 3 are all existing technologies and will not be described in detail here.
