TECHNICAL FIELD
[0001] The utility model relates to the rebound hammer field, concretely relates to a concrete rebound hammer convenient to operate. BACKGROUND
[0002] The rebound hammer is mainly used for measuring the strength of concrete, when using, one hand holds the middle part of the rebound hammer to play the role of righting, the other hand holds the tail part of the instrument to apply pressure to the instrument to measure the concrete surface, the operation gist of the rebound hammer during measurement is: ensuring that the rebound hammer axis is always perpendicular to the concrete test surface, the force is uniform and slow, and the righting is aligned with the test surface to slowly push forward to quickly read the display.
[0003] The perpendicularity is a necessary condition for measurement accuracy, the existing rebound hammer is mainly in the shape of a rod, and the two hands directly hold the rod-shaped rebound hammer to measure, which is inconvenient to hold by hand, and the balance of the hand holding the tail part of the rebound hammer is required to be higher (the arm cannot be in contact with the rebound hammer in the hand holding state, and the balance is not easy to grasp), and it is difficult to ensure the balance of the tail part after long-time and multiple measurements (16 times of measurement at one point), so it is necessary to research a concrete rebound hammer convenient to operate to solve the above problems. UTILITY MODEL CONTENTS
[0004] In order to solve the above problems, the utility model provides a concrete rebound hammer convenient to operate.
[0005] The utility model is realized through the following technical schemes:
[0006] A concrete rebound hammer convenient to operate, including rebound hammer body, the tail part of rebound hammer body is provided with an auxiliary handle convenient to hold, and the auxiliary handle is connected in an anti-loosening mode through a locking assembly of the front section of the rebound hammer body.
[0007] Further, the auxiliary handle includes a sheath sleeved on the tail part of the rebound hammer body, and the lower part of the sheath is provided with a handle in an inclined mode.
[0008] Further, the locking assembly includes a conical sleeve sleeved on the front section of the rebound hammer body, and the two sides of the conical sleeve are fixedly connected with U-shaped connecting pieces binding the sheath.
[0009] Further, the two sides of the sheath are provided with insertion holes, the U-shaped connecting pieces are inserted into the insertion holes on the two sides and the two ends of the U-shaped connecting pieces extend to the two sides of the conical sleeve.
[0010] Further, the two sides of the conical sleeve are provided with connecting columns connecting the end heads of the U-shaped connecting pieces, and the outer ends of the connecting columns are screwed with nuts limiting the end heads of the U-shaped connecting pieces.
[0011] Compared with the prior art, the utility model discloses the beneficial effects are: the utility model discloses the auxiliary handle of hand -held is established to the rebound hammer body tail portion, and is firmly connected through locking assembly, and the operation rebound hammer is more convenient convenient, and the perpendicularity of rebound hammer body and concrete surface is also more accurate, and the balance of rebound hammer body is better adjusted, and the requirement of vertical stability is guaranteed. BRIEF DESCRIPTION OF DRAWINGS
[0012] Figure 1 It is the three -dimensional structure schematic diagram of the utility model;
[0013] Figure 2 It is Figure 1 another state schematic view in the utility model;
[0014] In the drawing: rebound hammer body 1, display 2, sheath 3, handle 4, jack 5, U-shaped connecting piece 6, conical sleeve 7, connecting column 8, nut 9. DETAILED DESCRIPTION
[0015] The utility model will be described further in detail below in combination with the specific embodiment and the drawing:
[0016] As Figure 1 shown, a kind of concrete rebound hammer convenient to operate, including rebound hammer body 1, rebound hammer body 1 tail portion is established to the auxiliary handle of hand -held, auxiliary handle is connected by the locking assembly of rebound hammer body 1 front section to prevent loosening, avoid rebound hammer body 1 and auxiliary handle loosening by the connection of locking assembly, guarantee the stability of connection.
[0017] As Figure 1 shown, auxiliary handle includes the sheath 3 of being sleeved in the tail portion of rebound hammer body 1, the lower portion of sheath 3 is obliquely provided with handle 4, by hand gripping handle 4, the horizontality of arm and rebound hammer body 1 can be guaranteed, to facilitate control the contact angle of rebound hammer body 1 and concrete surface.
[0018] As Figure 1 , 2 shown, locking assembly includes the conical sleeve 7 of being sleeved in the front section of rebound hammer body 1, two sides of conical sleeve 7 are fixedly connected with the U-shaped connecting piece 6 of binding sheath 3.
[0019] As Figure 1 shown, both sides of sheath 3 are provided with jack 5, by the jack 5 of both sides insertion U-shaped connecting piece 6 and its both ends extend to both sides of conical sleeve 7.
[0020] As Figure 2 shown, the connecting column 8 of the end head of U-shaped connecting piece 6 is provided on both sides of conical sleeve 7, and the outer end of connecting column 8 is screwed with the nut 9 of the end head of U-shaped connecting piece 6.
[0021] The implementation principle of the embodiment of the concrete rebound hammer convenient to operate is as follows:
[0022] When measuring the strength of the concrete surface, one hand holds the front end of the rebound hammer body 1, and the other hand holds the handle 4 of the auxiliary handle. The sheath 3 is driven to balance and adjust the tail of the rebound hammer body 1 through the handle 4. The forearm of the hand holding the handle 4 is in the same straight line opposite to the rebound hammer body 1. As long as the forearm is kept perpendicular to the concrete surface, the perpendicularity of the rebound hammer body 1 to the concrete surface is more accurate. In this way, the balance of the rebound hammer body 1 is better adjusted, and the requirement of vertical stability is ensured.
[0023] When the rebound hammer is used for measurement and needs to be stored, the auxiliary handle can be disassembled. When disassembled, the nuts 9 on both sides are unscrewed and removed, and then the front end of the elastic U-shaped connecting piece 6 is removed from the connecting column 8. The U-shaped connecting piece 6 is pushed backward and pulled out from the tail of the insertion hole 5 of the sheath 3. Then the sheath 3 is removed from the tail of the rebound hammer body 1. In this way, the disassembly of the auxiliary handle is completed. When used, the reverse steps are used for installation. Through the connection of the locking assembly, the auxiliary handle is prevented from loosening, and the stable use of the rebound hammer body 1 is affected.
[0024] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments. The above embodiments and the description in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements. These changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
