Abstract

The utility model belongs to the field of sports equipment, and relates to a fixed device for tug-of-war. The device is formed by connecting a square steel pipe, a small square steel pipe, a round block, a steel chain, a steel round pipe, a handle, an indicator, a zero point, a number scale line, a plug pin, a support and a blocking sheet. The fixed device for the tug-of-war has the advantages that a user insert the plug pin into a small square steel pipe hole to control a game to start, when the tug-of-war is finished in a set time, and the indicator can indicate a score in quantification mode. When the game is finished, the round block butts against the outer lateral face of the square steel pipe to achieve a limit function, and the condition of hurt caused by the fact that a plurality of people in a winning party fall backwards collectively due to the fact that a party which already feels failure suddenly loosens a rope in the past is avoided. The fixed device for the tug-of-war is fixed outdoors so as to facilitate free use.

Description

The device that fixed tug-of-war is used

Technical field

The utility model belongs to field of sports equipment, relates to the device that a kind of fixed tug-of-war is used.

Background technology

At present tug-of-war pulls to one's own side's mode with the both sides of holding a rope with the personnel of two teams to be carried out, but has following problem: one, the beginning of rope move left and right inconvenience control match; Two, can't specifically quantize to show achievement during at the appointed time end of match; Three, above-mentioned tug-of-war mode is owing to lack the falling-resistant facility, and often generation has felt that the unexpected hand of the losing side decontrols rope, and the winner collective or many people can occur falls down backward to cause and hurt sb.'s feelings.

Summary of the invention

The purpose of this utility model is to provide a kind of and can the control match begins, quantize to show the device of tug-of-war achievement and energy falling-resistant, the technical scheme that adopts is by consisting of with lower member: the square steel tube lower end is embedded in the subsurface concrete fixing, little square steel tube passes the square steel tube upper aperture, be welded to connect respectively the circle gear at little square steel tube two ends, two the first screws pass respectively circle gear hole steel chain inner port and are fixedly connected with steel chain the inner, two the second screws pass respectively the outer end that two round metal pore steel chain external port are fixedly connected with steel chain, block end at two circles and be welded to connect handle, be welded to connect pointer in the handle middle and lower part, print and digital calibration line in the square steel tube upper surface at 0; Latch passes bracket holes, passes the catch hole again and is welded to connect, and support front end and square steel tube are welded to connect.

The beneficial effects of the utility model are: one, latch inserts the beginning that little square steel pore can be controlled match, and two, when at the appointed time tug-of-war finishes, pointer can quantize to show into achievement; Three, end of match time circle gear is against square steel tube lateral surface limit function, can avoid having felt that the unexpected hand of the losing side decontrols rope in the past, and the winner collective or many people can occur falls down backward and cause the situation of hurting sb.'s feelings to occur.Four, the utility model is fixed on the outdoor random use that made things convenient for.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is done in further detail explanation.

Fig. 1 is that master of the present utility model looks sketch;

Fig. 2 is that sketch is looked on the left side of Fig. 1;

Fig. 3 is the diagrammatic top view of Fig. 1;

Fig. 4 is that A-A of Fig. 3 analyses and observe the amplification sketch;

Fig. 5 is the simplified schematic diagram that Fig. 1 uses state.

The specific embodiment

With reference to accompanying drawing, square steel tube 8 lower ends are embedded in the 1 time concrete in ground fixing, little square steel tube 5 passes square steel tube 8 upper aperture, be welded to connect respectively circle gear 9 at little square steel tube two ends, two the first screws 4 pass respectively circle gear hole steel chain 10 inner port and are fixedly connected with steel chain the inner, two the second screws 3 pass respectively the outer end that two metal circular tubes, 2 hole steel chain external port are fixedly connected with steel chain, block end at two circles and be welded to connect handle 7, be welded to connect pointer 6 in the handle middle and lower part, print and digital calibration line 13 in the square steel tube upper surface at 0; Latch 11 passes support 12 holes, passes catch 14 holes again and is welded to connect, and support front end and square steel tube are welded to connect.

When using this device, opposing teams respectively hold metal circular tube, the referee holds handle pointer is moved to 0 point, before push and plug its front end of pin insert little square steel pore have the braking little square steel tube function, as shown in Figure 4, when the post-tensioning latch that declares the competition open breaks away from little square steel pore, little square steel tube can move left and right can play.Decidingly adopt following dual mode: win for we when drawing by square steel tube the circumference gear, as shown in Figure 5; The graduation mark of at the appointed time end of match pointed is the achievement of this innings, and it is cumulative deciding that several tolerances are changed into achievement.

Claims

1. device that fixed tug-of-war is used, it is characterized in that: square steel tube (8) lower end is embedded under the ground (1) fixing in the concrete, little square steel tube (5) passes the square steel tube upper aperture, be welded to connect respectively circle gear (9) at little square steel tube two ends, two the first screws (4) pass respectively circle gear hole steel chain (10) inner port and are fixedly connected with steel chain the inner, two the second screws (3) pass respectively the outer end that two metal circular tubes (2) hole steel chain external port is fixedly connected with steel chain, block end at two circles and be welded to connect handle (7), be welded to connect pointer (6) in the handle middle and lower part, print and digital calibration line (13) at 0 in the square steel tube upper surface, latch (11) passes support (12) hole, pass catch (14) hole again and be welded to connect, support front end and square steel tube are welded to connect.
