Description

Multi-functional shock-absorbing end caps for levels

technical field

The invention belongs to the technical field of spirit level accessories, in particular to a multifunctional shock-absorbing end cover for a spirit level.

Background technique

The existing spirit level body and end caps have no adsorption or vibration damping structures, which are prone to movement during use and affect the measurement accuracy; in addition, when the level is used outdoors and at high places, the level often fails due to improper operation. Falling from a high place and being damaged will cause inconvenience to the user.

Contents of the invention

The present invention aims at the deficiencies of the existing level that is easy to move during use and affects the measurement accuracy, the level has poor drop resistance, and the level is easily damaged after falling, and provides a multifunctional vibration-damping end for the level Cover, the multi-functional shock-absorbing end cap for the level can not only greatly reduce the damage caused by the level falling from a high place, but also increase the friction coefficient of the contact surface between the level and the object and have adsorption force, ensuring measurement accuracy.

The technical solution adopted by the present invention is accomplished in the following manner: a multifunctional shock-absorbing end cap for a spirit level, which includes an end cap main body, an end cap shock-absorbing cover, a spring fixing seat, and a sliding pad seat, wherein the end cap main body is Frame-shaped structure, at the upper and lower ends of the inner side of the main body of the end cover, there are tongues that match the sockets on the end face of the level ruler body, and on the front side panel of the main body of the end cover, there are screw holes that cooperate with the screws, and on the main body of the end cover There is a sliding pad mouth matched with the sliding pad on the rear side panel of the end cover, the end cover shock absorber is arranged on the outer end surface of the end cover main body, the spring fixing seat is fixed on the inner side of the front side panel of the end cover main body, and the sliding pad seat is composed of It consists of a seat frame and a panel. The length of the seat frame is larger than the opening size of the sliding gasket on the rear side panel of the end cover main body, and the size of the panel is slightly smaller than the opening size of the sliding gasket opening on the rear side panel of the end cover main body. The cushion seat is arranged on the inner side of the sliding cushion opening on the rear side panel of the end cover main body, and a spring is arranged between the spring fixing seat and the sliding cushion seat.

In the above structure, a sliding pad made of a low friction coefficient material is provided on the panel of the sliding pad seat; an anti-slip pad made of a high friction coefficient material is arranged next to the sliding pad, and the anti-slip pad is fixed on the anti-skid pad seat. On the level ruler body, wherein, the anti-skid pad is composed of a panel, a sliding pad seat frame baffle and a screw fixing post, the sliding pad seat frame baffle and the screw fixing post are fixed on the inner side of the panel, and the anti-skid pad is fixed on the The outer side of the panel of the non-slip pedestal.

In the above structure, the main body of the end cover, the spring fixing seat and the sliding seat are made of ABS engineering plastics.

In the above structure, the damping cover of the end cover is made of soft rubber material.

When the present invention is combined with a level, use screws to sequentially pass through the screw holes on the front panel of the end cover main body, the screw holes on the level body and the screw fixing column on the anti-skid pad seat, and the end cover main body, the level ruler The body and the non-slip pad seat are fastened together.

When no external force is applied to the level, under the elastic force of the spring, the seat frame of the sliding pedestal is against the rear side panel of the end cover main body, and the panel of the sliding pedestal provided with the sliding pad is lifted from the rear side panel of the end cover main body. Stretch out from the mouth of the sliding pad on the top, at this moment the height of the sliding pad is higher than the height of the anti-skid pad. When the level is in use, when the force applied to the level body is less than about 1kg, the sliding pad will touch the object, which facilitates the movement of the level body while the non-slip pad cannot touch the object. Moving up the measured object Due to the low friction coefficient of the sliding pad, the level can be easily moved to the required measurement position without scratching the surface of the measured object. When a force of more than 2kg is applied to the level body, the sliding pad retracts into the main body of the end cover. When the height of the sliding pad is lower than or equal to the height of the anti-slip pad, the anti-slip pad touches the object to be measured. The anti-slip pad is made of high friction coefficient material, which has a certain adsorption force on the object, so when the anti-slip pad is in contact with the measured object and the force applied to the level is greater, the adsorption between the level and the measured object will be greater. The firmer it is, the displacement of the level bar can be effectively prevented and the measurement accuracy can be ensured.

In use, when the level falls from a high place, the end cap shock-absorbing cover first touches the ground and acts as a buffer, effectively protecting the level from damage.

Compared with the existing level end cover, the multi-functional shock-absorbing end cap for the level of the present invention has the following characteristics:

1. It has strong drop resistance and impact resistance. When the level equipped with the present invention is in use, the level can withstand a vertical drop impact at a height of 2 meters without affecting the performance;

2. When the spirit level equipped with the present invention is in use, the spirit level can be conveniently moved on the measured object during the process of measurement and alignment without damaging the surface of the measured object;

3. When the spirit level equipped with the present invention is in use, the spirit level can be adsorbed on the surface of the object to be measured, so as to ensure that the correct position of the spirit level is not moved after measurement and alignment, and ensure the measurement and use accuracy of the spirit level.

The invention is particularly suitable as the end caps of various levels.
